Global Warming Thermodynamics
Thermodynamic Simulation and Analysis of Global Warming Indicators

Abstract
Historical data since 1880 shows that no correlation exists between air tem-
perature anomalies and atmospheric CO2
concentrations. However, that
strong pseudo-correlation from 1965 does exist implies
that there could be a
strong correlation between
the warming and waste heat because the latter
and CO2 are concurrent by-
products of fossil fuel combustion. Global
warming is a basic thermodynamic problem driven by huge amount of waste
heat from human activities that is about 80% of globally consumed en
ergy.
This article presents a climate change thermodynamic model of a quaternary
system consisting of air, land, oceans, and ices to investigate the warming
phenomena through a thermodynamic approach. Unique, definitive rela-
tionships exist between warming
or sea level rise and the amount of waste
heat allocated to each of the components according to their respective spe-
cific heat capacities. Simulation results of past temperature changes in air,
land, and seawaters as well as sea level rise are very well consistent with ob-
served anomalies and sea level rise measurements. The results suggest that
waste heat dominates global warming. This approach can also be used to
forecast future warming. Additionally, the climate system experienced a
transition from a cold to a warm era around 1980, before that time the sys-
tem was “heat” hungry. Reducing thermal emissions, increasing energy con-
version efficiency, and recover
ing and reusing waste heat are important
measures to effectively mitigate climate change.

1. Introduction
Global warming, or climate change, and extreme weather events threaten sus-
tainability. They occur more evidently at accelerated rates recently, and our
knowledge about them is still very limited.
1.1. GHG-Based Theory Unable to Well Explain Global
Warming/Climate Change
It is stated that about 90 percent of the infrared heat reflected upwards by the
earth’s surface after absorbing sunlight is then absorbed by atmospheric green-
house gases (GHGs) and radiated back to the earth’s surface [1]. This is referred
to as “heat trapping” or greenhouse effect. Human activities have increased at-
mospheric GHGs by over 48% since industrialization, which is believed to ex-
pand the greenhouse effect. It is also stated that “there’s a better than 95 percent
probability that human-produced greenhouse gases such as carbon dioxide, me-
thane and nitrous oxide have caused much of the observed increase in Earth’s
temperatures over the past 50-plus years” [1]. From these, it seems that GHGs
are the culprit and solar energy is the only energy source that GHGs trap and re-
flect back to the earth’s surface in the form of infrared radiation, leading to the
warming, but neglects the fact that waste heat (including residual heat) enters
the environment from human activities in the context.
Although the mainstream perceives that GHGs should be held accountable for
the warming based on the assumption that they form a “blanket” covering the
earth, exerting greenhouse effect and preventing heat radiations from escaping
to outer space, thus triggering global warming, this doesn’t seem to be supported
by the facts: 1) GHGs only share about 0.04%, a very trace amount, in the at-
mosphere; 2) GHGs have different specific gravities (air = 1, CO2 = 1.5189, CH4
= 0.5537, N2O = 1.530, O2 = 1.1044 [2]), randomly distribute in the atmosphere
spatially with CO2 and N2O mostly staying at the ground level, meaning that
they cannot form a “blanket” at a certain level with such a trace quantity; 3) ab-
sorbing and reflecting infrared radiations and other wavelengths of light are not
the unique characteristics of GHGs, everything with absolute temperature over
zero degree can absorb and emit radiations at certain wavelengths. Therefore,
other compositions in the atmosphere can also absorb and reflect radiations.
Additionally, GHGs should also absorb certain wavelengths of solar radiations.
They then emit and reflect radiations equally upwards and downwards because
of their statistically symmetrical distribution in the atmosphere, thus the solar
energy reaching the earth’s surface should be reduced after GHGs absorb its
infrared, causing a cooling effect eventually, if the theory were valid
i.e.
, GHGs
trap and reflect heat.
Further, if GHGs were responsible for the warming, they would articulate
quantitively the warmth in surface air, in land surface and sea surface as well as
the sea level rise,
i.e.
, a unique relation Δ

warming (Δ
tgw
) as well as sea level rise (Δ
Ls
). However, the fact is that no single
model can well simulate the air temperature changes, thus assembling all “satis-
factory” models’ simulations together, and taking their mean become an ap-
proach, although such an approach doesn’t make common scientific sense
(because if variables
x
and
y
correlate, theoretically only one relationship
y
=
f
(
x
) exists), the simulated results still cannot align well with the observations
(refer to Figure 9.8 in Reference [3]). Quantitatively explaining the temperature
changes in land surface and sea surface as well as sea level rise faces more chal-
lenges.
On the other hand, exploring the relation between CO2 concentration and the
surface air temperature anomalies finds that no correlation exists based on the
datasets from [4] [5] as shown in Figure 1, which exhibits the CO2 concentra-
tion (in ppm) and annual mean air temperature anomalies from 1880 to 2011.
The time span between 1880 and 2011 can be divided into four periods ac-
cording to the changes in annual mean anomalies: 1) 1880-1909 anomalies de-
creasing period; 2) 1910-1944 anomalies slight increasing period, 3) 1945-1964
anomalies very slow increasing period and 4) 1965-2011 anomalies rapid in-
creasing period as shown in the embed small figures on top of Figure 1. Clearly,
the air temperature anomalies and atmospheric CO2 concentration don’t corre-
late. However, a strong pseudo-relation does exist in the last period since 1965.
This finding is similar to Gosselin’s analysis [6]. Therefore, it is unlikely that
there is a single cause-effect between CO2 (also GHGs) and the global warming,
and even just from the pseudo-relation during the last period since 1965 to draw
that CO2 has incurred the warming is farfetched because CO2 is a concurrent
by-product with waste heat from the increased fossil fuel combustions. Adverse-
ly, CO2 and waste heat should correlate well (their relationship will be explored
later). The strong pseudo-relation between annual mean anomalies and CO2
since 1965 implies that waste heat may correlate to the air anomalies and may be
the real contributor to the temperature changes, or the global warming.
The GHG-based climate change theory has been facing strong challenges, al-
though a large number of models have been developed.
In addition, water vapor is a far more concentrated gas than GHGs in the at-
mosphere, it retains or traps much more heat than GHGs due to its greater spe-
cific heat capacity (SHC). Water on the earth and its vapor in the atmosphere
largely regulate the temperature of the environment we live in.
The climate system consists of four components: air, land, oceans, and ice. In
the previous study [7] [8], though sea ices are taken into consideration by re-
trieving their melted quantity from reported sea level rise, it is better to accu-
rately contemplate sea level rise reversely from ice melting.
Global warming is a basic thermodynamic phenomenon. Waste heat from
human activities can induce direct warming and ice melting. There should be
unique determinative relations between the waste heat and the warming in the
air, land, oceans, and ices melting as well as the sea level rise.

1.2. Energy Conservation and Waste Heat from Human Activities
According to the Law of Conservation of Energy or the First Law of Thermody-
namics, energy can be transformed from one form to another or others (e.g.,
coal through combustion to heat, electricity, and chemical energy contained in
new products), but cannot be created nor destroyed. It is obvious that while be-
ing used, part of the energy is inevitably transformed into a non-useful form as
residual or waste energy that dissipates into the environment.
Usually, we only consider how and how much energy is used, but are less
concerned about where the energy goes eventually. In fact, in every energy ap-
plication, it experiences a form transformation: from one form to another or
others. For example, when burning coal to boil water, the energy released from
combusting coal is converted to: 1) heat energy that heats up and boils the water,
2) heat energy that heats up the boiler case that eventually escapes into the envi-
ronment and 3) the energy that disperses into the environment along with flue
gas and water vapor. Among these three parts, the last two are obviously a kind
of waste heat (or waste energy) that is useless. Even for the first part, the heat
energy retained in the hot water is eventually released into the environment too
as residual heat, whether it is used for heating or for drinking. Thus, all these
three parts enter the climate system, and are referred to as waste heat.
Similarity exists in burning natural gas in the furnace, running air condition-
ers, cooking/baking, etc. in residential and commercial sectors from which the
amount of waste heat is almost the same as the amount of energy consumed [7]
[8].
In transportation, only a small part of consumed energy is used to move loads
and vehicles themselves for useful work, whereas the rest is dispersed into envi-
ronment through friction (which is then converted to heat) and sensible waste
heat from radiator, hot hood, and tail gas, etc. It’s estimated that about 75% of
the used fossil fuel energy in transportation is dispersed into the environment as
waste heat [7] [8].
In industries, the energy consumed is converted to several forms such as elec-
tricity, chemical energy retained in products and heat in addition to waste heat.
The widely used concept of energy efficiency cannot tell exactly how much
energy is ultimately converted to useful work or retained in products, it only in-
dicates how much of the input energy can be produced out during a process. For
example, when boiling drinking water using a modern kettle with an efficiency
of 90% (obviously it is very efficient), 90% of the consumed energy is used to
heat the water. However, it is unclear how much energy will be still contained in
the boiled water at its final state. Few people realize that almost all of this very
90% of the consumed energy is also released into the environment eventually, in
addition to the 10% already entered the environment even during the boiling
process. Cooking is another similar example. Thus, a new concept to describe
how much of the consumed energy is really converted to useful work or energy
retained in products is necessary, which is referred to as energy’s effective con-

Open Access Library Journal
version efficiency (EECE) [7] [8]. It is the EECE that can clearly tell how much
consumed energy is dissipated to the environment during a process.
As analyses shown in [7] [8], in the residential and commercial sectors, al-
most all the energy consumed is eventually dissipated into the environment. In
transportation, only about 25% of the consumed fossil fuels is converted to
useful work by considering the different levels of technologies across the
world, and the rest,
i.e.
, 75%, is wasted into the environment through friction
and sensible heat. In industries, it is assumed that the entire EECE is about
30% across all sectors.
According to BP [9], industries consume about 51% of the global energy, res-
idential and commercial 29% and transport 20% (these shares may vary from
time to time, but the variance should be reasonably small). Thus, it is estimated
that the global EECE is about 20%, which means about 80% of the energy con-
sumed globally enters the environment as waste heat [7] [8]. This is reasonable if
considering the different technology levels in the world, and even in the USA
with the most advanced technologies, the waste heat is reported to be about 67%
of the consumed energy because of the inefficiencies in energy application
processes, equipment [10].
BP has adjusted its estimate of a standard power plant’s thermal efficiency
from 36% in 2000 to 40.4% in 2019 [11] [12] in the last two decades, while re-
maining 36% for the period of 1965-2000, to reflect the technology advance-
ments. Nevertheless, from the perspective of global energy application, this ad-
justment would not affect much on the global EECE since the basics of the
energy application processes have not been changed radically. Therefore, assume
the EECE is 20%, although during earlier years (say, 1965 to 1979, only after that
point climate change has become more recognized) a lower EECE might exist
because of less advanced technologies, especially in developing countries.
Besides, countless flaring and spontaneous firing of surface coal and methane
from the natural reservoirs, volcanic eruptions, forestry wildfires and various
chemical fuel applications (such as space explorations, military activities, etc.)
also send a huge amount of heat to the climate system, contributing to the global
warming.
2. Climate Change Thermodynamics
The climate system consists of land, oceans, air, and ices. It receives energy from
sun, interior earth, and moon, etc. to sustain the earth environment human lives
in. The energy reaching the earth surface retains at a dynamic energy budget
balance as expressed below, which provides enough energy for the entire system.

surface is quite stable although a small temperature change of about 0.05˚C -
0.1˚C has been detected due to the variance in total solar irradiance during the
11-year solar cycle [13] [14], while the energy from moon is less studied and
very limitedly known, compared to the solar one, but consideredly remains sta-
ble in the past long history.

i.e.
, energy absorbed by and stored in plants or biomass as

energy collected through photovoltaic process, etc.
As described in [8], it is this dynamic energy budget balance that enabled the
climate system to maintain the temperatures of air, land, and seawaters relatively
stable over a long period. Any extra energy entered the system from human ac-
tivities such as combusting fossil fuels, using geothermal or nuclear energy will
certainly shift the above energy budget balance to the right side, making the air,
land, and seawaters warmer, and thawing ices. Deforestation decreases Ebio con-
verted from solar energy, thus the corresponding excessive energy contributes to
the warming. However, details on deforestation’s effect need further studies. It
also needs attention that combusting biomass releases long-term accumulated
energy back to the system concentratedly, breaking the local energy budget bal-
ance, and thus contributing to the warming.
Global warming is a basic thermodynamic problem. Warming a house by us-
ing heat energy not only warms the air in the house, but also the waters in con-
tainers, the floor, and walls, etc. Similarly, the globe warms from the surface lev-
el,
i.e.
, at surface air, land surface, seawaters surface, and ices. As indicated in the
earlier articles [7] [8], the huge amount of waste heat entered the climate system
induces the warming, following the thermodynamic laws.
As well known, heat always rises along with the air. In the climate system heat
extends towards the poles along with the vortex of air that forms around the
earth surface as the earth rotates. This attracts much heat energy to the polar
areas, especially the North since the north hemisphere is much more populated,
more energy consumed, and consequently more waste heat dissipated than in
the South. This may help understand why the “Arctic Amplification” [15],
i.e.
the evident Arctic warming happens in the last decades, where more glaciers, ice
sheets and covers melt, permafrost thaws and increasing heat waves than ever
before, as Walsh said “The Arctic has been warming twice as fast as the rest of
the world. In some seasons, it has warmed three times faster than the rest of the
globe [16].
2.1. Equivalent Climate Change Model
Equivalent Climate Change Model (ECCM) has been developed to explain the

warming phenomena, consisting of respective equivalent climate change boun-
dary layers to simulate temperature changes in surface air, land surface, and
seawaters surface [7] [8]. The results show that the simulated temperature
changes are well consistent with those observed anomalies in air, land, and
oceans, respectively. However, ice melting was not considered in the same way,
instead, it was considered through the observed sea level rise based on NASA’s
assumption that one-third of the rise is from sea water warming and two-thirds
are from ice melting [15] [17]. In fact, this is not an appropriate approach and
cannot fully explain how ices respond to human activities and how ices melt and
contribute to sea level rise.
2.2. Climate Change Thermodynamic Model
In the present study, melting of both ices (glaciers, icebergs, and ice shelves) and
sea ices (
i.e.
, ice sheets and covers) is considered thermodynamically based on
the SHC and latent heat of fusion. Incorporating this into the existing ECCM [7]
[8] constitutes a new climate change thermodynamic model (CCTM) that in-
cludes a thermodynamically equivalent climate change surface air layer (or col-
umn), a thermodynamically equivalent climate change land surface layer, a
thermodynamically equivalent climate change seawaters surface layer, and the
melting of glaciers and sea ices. They absorb the waste heat from human activi-
ties according to their respective SHC.

2.3. Methods
As described in [7] [8], the feature of this study is using SHC to allocate heat en-
tered the climate system from human activities to the components: air, land,
oceans, sea ices and glaciers.
Sea ices (including ice sheets and covers) behave very differently than pure ice
because they contain brine and salts. They melt at different temperatures than
they form. Seawaters freeze at about 2.0˚C [20] - 1.8˚C [21] to form sea ices
due to the salinity. The resulting ices trap brine that either precipitates or drains
out of the ice crystal lattice [22], forming brine pockets and eventually flowing

Open Access Library Journal
into the oceans again. As a result, the bulk salinity in sea ices is much lower than
that in seawaters (34 - 35 parts per thousand,
i.e.
, ppts). For old and matured sea
ices it is estimated the salinity ranges from 4 to 12 ppts (4 ppts is widely used for
bulk sea ices) although some have lower or greater values, while for new ices or
those at the bottom of ice sheets (or covers) the salinity may be greater, for ex-
ample, new ices can be of between 12% - 20% [23] when growing from seawaters
with normal salinity of 32 - 35 ppts or greater. Further cooling during winter
reduces salinity. Therefore, it is reasonable to consider that the salinity of sea
ices melted during the melting season has reduced gradually from early years
when more new ice was formed around the matured ones, and the amount of
new ice reduces recently as the global warming proceeds.
Similar to pure ice, sea ices are resistant to melting because it needs more heat
(
i.e.
, latent heat of fusion) to go through the phase transformation. Because of
very limited knowledge and data on sea ices behavior and physicochemical
properties, details of the formation and ablation are not very clear yet, and much
less is known about how sea ices melt in the real ocean environment, however
the process is very complicated. Sea ices melt at distinguishingly higher temper-
atures than the freezing points (2.0 [20] - 1.8˚C [21]). From Spring to Au-
tumn seawaters and surface air over them become warmer, it is hypothesized
that when the in-situ temperature in the bulk sea ices exceeds a point at which
the ice - brine pocket remains at microscopic level equilibrium at the interface
[19], the melting process initiates, meltwater diluting the brine solution in the
pocket, enlarging the brine flux channel and accelerating the ice melting, as a
result, increasing sea ices melt. Towards summer, temperature becomes higher
and the melting speeds up. Sea ices can melt completely at a temperature (
Tf
)
determined by the following equation [19],
f m si
T mS=
(7)
For example, the potentially complete melting temperature is about 0.22˚C
when the salinity (
Ssi
) is 4 ppts and enough heat energy is available. However,
due to the vast volume of sea ices and relatively limited heat availability, only a
part of the ices can melt before getting into winter to re-form ices.
As such, it is anticipated that no evident phase transformation (or fusion)
from sea ices to seawaters can be observed, at a certain temperature, that can be
expected by a certain value of latent heat of fusion, instead, a transitional process
exists that merges the phase transformation into a melting process. Under such a
situation, using sea ices’ effective specific heat capacity (ESHC) [19] [22] is more
appropriate. ESHC includes the latent heat for phase transformation (
i.e.
, fu-
sion) that accompanies temperature change in sea ices [19]. Furthermore, the
latent heat of fusion is a function of salinity and temperature [19] [22] [24].
According to Ono [24], sea ices’ ESHC can be expressed as below:

Similarly, using effective latent heat of fusion to describe sea ices heat re-
quirement during phase transformation is advisable. Sea ices’ effective latent
heat of fusion can be expressed as below according to Petrich

Assuming the values of salinity of sea ices are as indicated in Table 1 for this
study period concerned, where they are decreasing gradually due to less forma-
tion of new sea ices, and this decrease escalates in recent decades as warming
accelerates.
Meanwhile, the ESHC of sea ices at −2˚C (the most conservatively highest
temperature at which it is in a steady state), the melting point temperature for
potentially melting completely as well as the latent heat of fusion at the melting
point that are calculated from Equations (7)-(9a) are also included in Table 1.
For air, its SHC depends on the temperature and the moisture content, and
the latter can be derived from relative humidity. Air SHC is calculated by the
equation in [25] with the procedures prescribed in [8],
i.e.
, obtaining the abso-
lute humidity from relative humidity and then water vapor’s SHC at the corres-
ponding temperature. Table 2 shows the surface air’s temperature, relative hu-
midity, absolute humidity, water vapor’s SHC and finally the air’s SHC. The wa-
ter vapor’s SHC at 20˚C is obtained by simple linear interpolation between 2˚C
(
i.e.
, 275 K, 1.859 KJKg−1∙K−1) and 27˚C (
i.e.
, 300 K, 1.864 KJKg−1∙K−1) [26]. The
global average of air relative humidity and temperatures are obtained from the
respective datasets [27] and [28] on an annual basis.
For seawaters, its SHC is determined by its surface temperature that is aver-
aged from the datasets [29] annually, and the corresponding SHC is about 4.004
KJKg−1∙K−1 at the corresponding temperature range of 13˚C - 14˚C [30] as
shown in Table 3.
The land’s SHC is assumed to be 0.83 KJKg−1∙K−1 from [31].
Therefore, the relative strengths of SHCs (or simply SHC shares) of air, sea-
waters, land, sea ices, and glaciers in the climate system are summarized in Ta-
ble 4 for the study period, which determines how much heat will be allocated to
each component respectively.

non-renewable energy consumption, the energy entered the climate system as
waste heat from human activities (EECE = 20% as discussed earlier), and the
energy allocated to air, seawaters, land as well as sea ices and glaciers are shown
in Table 5. The allocation is calculated based on the waste heat multiplied by the
corresponding share percentage of each component’s SHC as shown in Table 4.
It is mentioned earlier that both waste heat and CO2 are concurrent by-products
of fossil fuel burning. Figure 2 shows their strong correlation. Clearly this cor-
relation is much stronger (correlation coefficient R2 = 0.9839) than that between
the temperature anomalies and CO2 (correlation coefficient R2 = 0.8677) shown
in the small figure at the top right in Figure 1 for the same period of 1965 ~
2011, implying that air temperature anomalies could be more reasonably due to
waste heat, as opposed to increased CO2 or GHGs. It is worth noting that the

Note: The difference between global primary energy consumption and global consumption of non-renewable energy is the
amount of total renewable energy that includes solar, wind, hydro, and biomassreferred to as surface renewable energy (geo-
thermal should not be included in the renewable energy category, but in BP’s report [32] the geothermal is instead included in the
renewable energy. Due to its small amount this won’t affect the results).
CO2 here comes from various sources, not just combustion. However, if only
considering CO2 from fossil fuel burning, it is anticipated that the correlation
between them should be much stronger. Later, the effects of waste heat on sur-
face air, land and seawaters surface temperature anomalies and on sea level rise
will also be investigated and confirmed.
If this is true, then CO2 from combustion could serve as an indirect and easy
indicator to assess how much waste heat pumped into the system and conse-
quently how it impacts the system.

i.e.
, NASA_Lowess (5)) [33] are also shown for comparison.

also exhibited.
From Figure 3, it is clear that in most of the time, especially the last four dec-
ades, the observed anomalies are very consistent with the calculated results at the
surface air boundary layer depth between 20 - 30 meters, and the Lowess
smoothing anomalies [33] are much closer to that calculated at the depth of 25
meters.
Therefore, it is reasonable to draw that a surface air column with a depth be-
tween 20 - 30 meters can be considered equivalent in simulating its warming
trend, with a 25-meter depth being a representative. However, before late 1970s
this is not true, observed anomalies are much less than those calculated.
Plotting the calculated results of air temperature changes at the surface air
boundary layer depth of 25 meters, NASA Annual Mean and Lowess smoothing
values [33] with the energy entered the surface air obtains the left in Figure 4, in
which the corresponding trend lines are also exhibited. The black solid line on
blue dots represents the strongest relation between the simulation results and the
energy entered the air with a correlation coefficient of 1, which is understanda-
ble. The green triangles and dash line represent NASA’s annual mean anomalies,
the red squares and dot line represent Lowess 5-year smoothing values. It is no-
ticeable that the red dot line and the green dash line are almost overlapped, with
their respective correlation coefficients being 0.9361 and 0.8769 (Figure 4, Left),
advising that the correlations between these observational values and the energy
quantities are very strong. Furthermore, these trend lines of observational values
are also very close to that of the simulations.
As indicated earlier, obvious differences exist between the observations and
the simulations until late 1970s. Excluding these data points and only taking the
rest points since 1980 is indicated at the right in Figure 4. It can be seen that
while the simulations with the energy entered the surface air still show the
strongest relation with the correlation coefficient of 1, NASA’s-Annual Mean
Figure 4. Correlations between surface air temperature changes (anomalies) and the energy entered the surface air layer. Blue dots
and the black line show the relation between temperature changes calculated by Equation (2) and the energy entered the air with a
correlation coefficient of 1; Green triangles and the green dash line represent NASA’s annual mean anomalies [33]; Red squares
and the red dot line represent NASA’s Lowess smoothing results of the observations [33]. Left: during the period of 1965-2019;

and NASA’s Lowess smoothing against the energy entered the air still exhibit
respectively strong relations with big correlation coefficients of 0.8669 and
0.9618, and their trend lines are much closer to that of the simulations, and even
they almost overlap each other, compared to those in the left figure for the pe-
riod of 1965-2019. This is not by accident.
All these suggest that the temperature changes or anomalies in the surface air
are strongly linked to the extra energy (
i.e.
, waste heat here) entered the air, pro-
viding direct evidence that energy beyond the earth’s energy budget balance en-
tered the surface air caused the air temperature increase. This approach can be
used to predict the future surface air temperature rises.
3.2. Land Surface Temperature Changes
Simulations of land surface temperature changes by using Equation (3) and the
energy entered the land in Table 5 are shown in Figure 5, in which NASA’s an-
nual mean and 5-year Lowess smoothing of observed land temperature anoma-
lies [33] are exhibited as well.
Clearly Figure 5 shows the similar trends to surface air temperature changes
as seen in Figure 3. Before late 1970s the observed anomalies deviate obviously
from the simulations, with more negative anomalies; during the 1980s and 1990s
the observed anomalies fluctuate between the simulations at a boundary layer
depth of 0.015 and 0.15 meters, while in the last two decades the observed ano-
malies fall within the simulations between boundary layer depths of 0.0175 and
0.03 meters, and a depth of 0.025 meters can be a good representative since 1980.
Figure 5. Simulations of global land surface temperature changes at different land surface boundary layer depths during
1965-2019. NASA’s annual mean of observed anomalies (
i.e.
, NASA_Land_Annual) and 5-year moving Lowess smoothing (
i.e.
,
NASA_Land_Lowess (5)) [33] are also shown for comparison.

These variations may have reflected the changes in methods and technologies of
measurements as well as in natural conditions on the land surface such as vege-
tation covers as well as the effect of ice melting (the land is the most susceptible
to any heat changes because of its smallest SHC among the components).
Plotting the simulation results at the boundary layer depth of 0.025 meters,
observed anomalies (NASA_Land_Annual_mean and NASA_Land_Lowess)
against the energy entered the land surface are shown in Figure 6: Leftthe data
from 1965-2019 and Rightthe data from 1980-2019, revealing clearly that
strong relationships exist either for the NASA_Land_Annual_mean vs the ener-
gy or the NASA_Land_Lowess vs the energy, and both have big correlation coef-
ficients, while the simulation’s correlation coefficient is 1.
Again, after excluding the data before 1980, the observational trends
(NASA_Land_Annual_mean and NASA_Land_Lowess) in the right figure of
Figure 6 are much closer to the simulations than shown in the left. All these in-
dicate that strong relationship exists between the land surface temperature
change and the energy absorbed. This approach can be used to predict the future
land surface temperature rises.
3.3. Sea Surface Temperature Changes
Simulations of sea surface temperature changes by using Equation (4) and the
energy entered sea surface waters in Table 5 are shown in Figure 7, in which
NASA’s annual mean and 5-year Lowess smoothing of observed sea surface
temperature anomalies [33], NOAA’s annual anomalies [35] are exhibited too.
Similarly, before late 1970s the observed anomalies deviate obviously from the
simulations, with more negative anomalies. During 1980s and 1990s the ob-
served anomalies fluctuate between the simulations at boundary layer depth of
0.03 and 0.1 meters, while in the last two decades the observed anomalies fall

within the simulations between boundary layer depth of 0.04 and 0.08 meters,
and a depth of 0.06 meters can be a good representation since 1980. These varia-
tions may have reflected the changes in methods and technologies of measure-
ments, in natural conditions of the sea surfaces such as the chemical and physi-
cal properties of surface seawaters as well as the effect of ice melting.
Plotting the simulation results at the seawaters boundary layer depth of 0.06
meters, observed anomalies (NASA_Ocean_Annual, NASA_Ocean_Lowess and
NOAA_Ocean_Annual) against the energy entered the seawaters are shown in
Figure 8: Left contains the data from 1965-2019 and Right contains data from
1980-2019, revealing clearly that strong relationships exist either for the
NASA_Ocean_Annual vs the energy or the NASA_Ocean_Lowess vs the energy,
or NOAA_Ocean_Annual vs the energy. All these observed anomalies trend
lines have big correlation coefficients (about 0.80 or greater), and the simula-
tion’s correlation coefficient is 1.
Additionally, it is very interesting that the NOAA_Ocean_Annual trend line is
almost parrallel to the simulation one (
cf.
their slopes), which is important and
supports that the temperature changes are due to the contribution of energy. In
general, all these indicate that strong relationship exists between the sea surface
temperature changes and the energy absorbed.
This approach can be used to predict the future sea surface temperature rises.

Sea level rise consists of the following: 1) added depth from melted ices (or
meltwaters), 2) added depth from meltwaters due to thermal expansion from
melting point to the average of global sea surface temperatures, 3) added depth
of meltwaters due to thermal expansion from seawaters warming and 4) added
depth due to thermal expansion of bulk seawaters warming.
Specifically, the contribution from sea ices melting can be calculated as below:
1) added depth from melted sea ices;
2) added depth from melted sea ices due to thermal expansion from melting
point (Table 1) to the average of global seawater surface temperature. The aver-
age seawater surface temperature during the melting season (May ~ Sept) is de-
termined from the NCEI’s ERSST V4 datasets [29] as shown in Table 3;
3) added depth from melted sea ices due to thermal expansion from the sur-
face seawaters warming,
i.e.
, seawater surface temperature rising as discussed in
the foresaid section “Sea Surface Temperature Change”. The value of tempera-
ture rising is that calculated at the sea surface boundary layer depth of 0.06 me-
ters.
The contribution from glaciers can be calculated as below:
1) added depth from melted glaciers;
2) added depth from melted glaciers due to thermal expansion from melting
point (
i.e.
, 0˚C) to the corresponding global average seawater surface tempera-
ture (Table 3). The corresponding average seawater surface temperature at the
melting seasons (May ~ Sept) is determined from the NCEI’s ERSST V4 datasets
[29];
3) added depth from melted glaciers due to thermal expansion from the sur-
face seawater warming,
i.e.
, seawater surface temperature rising as discussed in
the foresaid section “Sea Surface Temperature Change”. The value of tempera-
ture rising is that calculated at the seawater surface boundary layer depth of 0.06
meters.
Seawaters (including the deep waters) are subject to thermal expansion due to
the cumulated entrained heat energy. According to Luann D. and Rebecca L.
[36], “the 1993-2020 heat-gain rates (in oceans) were 0.37 - 0.41 Watts per
square meter for depths from 0 - 700 meters, depending on which research
groups analysis you consult. Meanwhile, heat gain rates were 0.15 - 0.31 Watts
per square meter for depths of 700 - 2000 meters. For depths between 2000 -
6000 meters, the estimated increase was 0.06 Watts per square meter for the pe-
riod from June 1992 to July 2011”, the average temperature rise due to this heat
gain is estimated about 3.23446E05˚C per year for the full ocean depths. Sup-
pose this temperature rise applies to the entire period of this study and a depth
of 2000 meters is taken as a representative for the entire ocean depths, seawaters’
thermal expansion coefficient is 1.57E4 K−1 under the pressure of 2000 decibars
(in oceans one meter depth is about equivalent to 1 decibar) and 5˚C at a salinity
of 35 ppts [37].
The simulated global sea level rise (GSLR) that accumulates annually is shown

in Figure 10, where the measured global mean sea level rise (GMSL, mm) [38] is
also exhibited. Clearly, they have similar trends. Since the GMSL is an accumu-
lated record since 1880, and in 1965 its value is 86.8 mm, adjusting the GMSL by
subtracting 85 mm can easily compare with the simulations which start from
1965. The adjusted GMSL (
i.e.
, GMSL-85) is also shown in Figure 10. Clearly at
an early time the simulation is very close to the measurements, however, an in-
creasing departure from the simulation appears with time especially in the last
two decades. The potential reasons for this departure may be attributed to 1)
volcanic eruptions, wildfires, coal fires [39], natural gas fires and explosions [40]
[41], flares as well as various chemical fuels used in military and space explora-
tions, etc.; 2) increase in the amount of melted multiple-year sea ices in which
salinity is very low and even close to zero (0), compared to simulations with
higher salinity.
Increased volcanic eruptions have been reported since 2000 [42], although the
actual number may be greater and possibly remain unchanged due to inaccessi-
bility and technological difficulties. Volcanic eruptions eject substantial energy
into the climate system that can change the climate, for example, the eruption of
Mount St. Helens in 1980 released 24 megatons of thermal energy, equivalent to
1600 times the size of the atomic bomb dropped on Hiroshima [43], that is about
0.1E+15 KJ. However, huge amount of volcanic dust, etc. may also shelter solar
radiations, leading to a decrease in the temperature in the system afterwards.
Additionally, wildfires occur recently more frequently and intensively such as
those in California and Australia. According to Jonathan [44], the annual energy
released from wildfires in Western United States is about 1.4E+15 KJ. Although
these wildfires are fueled by the biomass that is included in the earth’s energy
budget balance during a long growing time, the concentrated burning and

release of this cumulated energy in a short time will impact the system’s behavior.
These compounding effects are significant on the system.
Figure 11 plots the sea level rise (both simulated sea level rise,
i.e.
, cumulated
calculated GSLR and GMSL-85) against the energy associated with ice melting
(
i.e.
, the sum of the energies melting sea ices and glaciers respectively). Poly-
nomial regressions show clearly that both the measurements and the simulations
have strong correlations with the energy.
According to the regression of GMSL-85 in Figure 11, the energy that melted
ices (
i.e.
, sea ices and glaciers) in 2019 should be 339.84E+15 KJ, compared to
the allocated waste heat of 324.02E+15 KJ, the difference of 15.82E+15 KJ could
be the extra energy coming from those forementioned energy sources. It is
known that in 2019 the energy allocated to melting sea ices and glaciers is about
78.65% of total waste heat entered the climate system, thus this extra energy
melting the ices corresponds to a total extra energy of 20.12E+15 KJ. That would
contribute to extra temperature rises in air, land, and oceans of about 0.021˚C
(depth: 25 m), 0.028˚C (depth: 0.025 m) and 0.014˚C (depth: 0.06 m), respec-
tively. These correspond to adjusted simulation results of 0.97˚C, 1.34˚C and
0.67˚C, being much closer to their corresponding observations: 0.99˚C, 1.44˚C
and 0.68˚C [33].
Furthermore, Figure 12 shows the contributions to sea level rise of sea ices
melting, glaciers melting and bulk seawaters warming on an annual basis (top)
and cumulated basis (bottom) when sea ice salinity changes from 12 (1965) to 4
ppts (2019). Clearly, on an annual basis (top), the melting of sea ices is the do-
minant contributor to sea level rise, sharing about 90.2% - 95.6%, and glaciers
contributing about 3.6% - 9.5% while bulk seawaters warming only contributes
about 0.4% - 1.2%.

On the cumulated basis (bottom), the melting of sea ices still dominates the
sea level rise, with its contribution ranging from 93.6% - 95.5%, glaciers melting
contributes about 3.6% - 5.8% and bulk seawaters warming only shares about
0.5% - 1.2%.
We can therefore forecast future sea level rise if the salinity in sea ices and the
global EECE as well as global energy consumption, etc. are known.

3.5.1. Cold Era and Warm Era
According to NOAA [45], the Earth has experienced a gradual warming since
the early 1900s as indicated in Figure 13 in which before 1900 the globe was
cooling gradually from 1880. The fluctuations in temperature anomalies between

Figure 13. Global land and ocean (
i.e.
, surface air) temperature anomalies from 1880 to 2020 based on NOAA’s analyses [45].
Earth was in a gradual cooling period until the early 1900s, then turned to gradually warming although there were fluctuations in
the temperature anomalies between the 1940s and late 1970s, which might be attributed to ENSO cycles: El Niño and La Niña, etc.
the early 1940s and late 1970s suggest that this is a transitional period and sus-
ceptive to any disturbance due to the ENSO cycles,
i.e.
, El Niño and La Niña, etc.
Alternatively, when looking at the heat content in oceans (Figure 14), a simi-
lar phenomenon is observed that before around mid-1980s the heat energy in
the top half-mile depth of the oceans is negative compared to the average be-
tween 1955 and 2006 [36], which indicates that the oceans were heat energy
“hungry”,
i.e.
, “aggressively” absorbing heat, and after that the oceans are “rich”
in heat and storing more heat.
These suggest that the globe has experienced a change from a “cold” era to a
warm one as the warming proceeds. These changes are generally consistent with
the changes in sea surface temperatures as shown in Figure 15 [29], where, si-
milarly, the temperature was declining before 1904 and thereafter turning to an
increasing trend journey, which coincides with Figure 1. This can be attributed
to the industrialization that has consumed increasingly more fossil fuels and dis-
sipated more waste heat into the climate system, driving the warming.
However, a time lag (several decades) exists between the two phenomena
shown in Figure 13 and Figure 14, which is dependent on the baseline used and
due to the difference between their medium’s SHC. Although the time points at
which the values of temperature anomalies and heat content turn from negative
to positive are different, it is reasonable to believe that the Earth entered a warm
era from around 1980.
This cold-to-warm-era transition can easily explain what we’ve seen in the

simulations of temperature changes in surface air, land surface, and seawaters
surface in the early years where the simulation results are always greater than the
measurements. This is due to in the cold era the system (including air, land,
seawaters, especially ices and possibly permafrost) needs great deal of heat to
balance its energy requirement. However, we need more knowledge about the
system then to better understand its behaviors.
Additionally, permafrost may also contribute to the early “abnormal” beha-
viors in air, land, and seawaters’ temperature anomalies by absorbing much heat
before exhibiting evidence of “thawing”. As discussed above, large amount of
waste heat has been cumulated towards the polar areas, especially the North be-
cause of the densified population, increased fossil fuel consumption and thus in-
creased associated waste heat release, via the atmospheric vortexes.
3.5.2. Global Warming Forecast
Figure 16 shows the waste heat energy distribution in the climate system where
the steps indicate the change of salinity in sea ices. Among the total energy that
entered the climate system, about 92.8% - 96.8% entered the oceans through
melting sea ices and glaciers, warming surface seawaters (this aligns well with
the estimate by Luann D. and Rebecca L. [36], and Figure 14 above), 1.9% -
4.3% absorbed by air, with the remainder (about 1.3% - 2.9%) absorbed by the
land. Oceans therefore become the primary energy storage, the buffer and regu-
lator of temperature changes in the system.
If the energy (mainly non-renewable energy) consumption, energy effective
conversion efficiency and the salinity in sea ices are known, it is possible to

forecast the temperature increases in surface air, land, and oceans as well as sea
level rise with very good certainty and reliability.
There are two methods that can be used for forecasting future temperature
rises in air, land and oceans, and sea level rise. One is based on the thermody-
namic equations as discussed earlier; and another is based on the empirical re-
gression equations found in the corresponding regression figures above.
Using the thermodynamic equations and the 2020 global energy consumption
[32], the calculated temperature rises in surface air, land, and oceans are 0.90˚C,
1.24˚C, 0.62˚C, respectively, and the sea level rise is 104.7 mm. They are close to
the observations: surface air 0.98˚C, land surface 1.58˚C, sea surface 0.75˚C [46],
sea level rise 91.3 mm [47], although differences exist that can be attributed to
the extra heat energy from natural sources and chemical fuels as discussed earli-
er. If considering these extra energy contributions, these simulated values will be
much closer to what observed. Remember that 2020 was the second warmest
year in the 141-year record for air surface, and the hottest one for land surface
[48] (large scale wildfires might have contributed to the hottest land surface),
this may help to understand why such differences exist.
BP’s 2020 Energy Outlook [49] imagines three possible scenarios
i.e.
, Rapid,
NetZero and Business-as-usual (BAU), regarding how the energy economy
would be transitioned in future. The energy consumptions in 2050 are estimated
in Table 6 where renewables consist of wind, solar and biofuels. It is noted that
the biofules also include geothermal. The latter is a non-surface renewable ener-
gy and should be considered in the simulation, but its amount is very small, thus
its impacts on the earth’s energy budget balance can be negligeable. Besides, the
non-combusted fossils such as feedstocks for petrochemicals, etc. are excluded
from this calculation.
Assuming that in 2050 the salinity in sea ices remain 4 ppts, global sea surface
temperature about 14.5˚C and the polar areas’ sea surface temperature in the
melting season is about 0.2˚C, the EECE is 20% under BAU, 30% under Rapid

and 25% under NetZero scenarios. The forecast values of the climate change in-
dicators (temperature risings of surface air, land surface, sea surface and sea level
rise) are shown in Table 7. The forecast for temperature changes is performed by
the two aforesaid methods: theoretical methods with Equations (2)-(4); Regression
equations of simulated results and regression equations of measurements in Fig-
ure 4, Figure 6, Figure 8 and Figure 11, respectively. With the endeavors and
measures to be taken, the climate change indicators are remarkably suppressed
under the forecast energy consumption scenarios compared to the current levels.
The results produced by different methods are very close for temperatures.
With respect to sea level rise, the situation is little different as shown in Table
7, because decreased fossil fuels and increased surface renewables will be con-
sumed. Using the theoretical method produces similar results under the three
scenarios, which is very reliable by comparing to the current rise in sea level.
Under BAU using three methods creates slightly different results, with the big-
gest one from Adjusted GMSL regression, while under Rapid and NetZero sce-
narios, the two regression methods produce much less results than those by
theoretical method. Among the three methods, using Cumulated Calculated
GSLR regression produces the smallest results under all three scenarios. Conse-
quently, using the theoretical approach provided by this thermodynamic model
to forecast sea level rise is highly effective and recommended. Using empirical
regression methods largely underestimates concentratedly-consumed surface
renewable energies’ impacts

(EECE) at various processes, sea ices salinity, melting point and thermodynamic
properties of permafrost (density, SHC, melting points, etc). Therefore, collect-
ing more accurate and reliable data will be crucial to allow accurate future mod-
elling.
Additionally, greater attention should be paid to the relationship between ex-
treme weather events and the heat accumulated in the environment, especially in
oceans.
4. Conclusions
From these analyses, it is clear that there is no correlation between atmospheric
CO2 or GHGs and the surface air temperature anomalies, which means GHGs
and global warming don’t have a cause-effect relation. CO2 (and other GHGs)
and waste heat are concurrent by-products of fossil fuel combustions, they cor-
relate strongly.
Global warming correlates strongly with the waste heat. A huge amount of
waste heat from human activities provides enough energy to warm the climate
system: arising temperatures of air, land, and oceans as well as melting ices (sea
ices and glaciers) to raise sea level. Waste heat distributes among the compo-
nents of the climate system according to their specific heat capacities, about
92.8% - 96.8% entered oceans through melting ice and warming seawaters, 1.9%
- 4.3% into the air and 1.3% - 2.9% into the land. The climate system had transi-
tioned from a cold to a warm era around 1980.
Thermodynamic simulations by means of the climate change thermodynamic
model are well consistent with the observations in air, land and oceans’ temper-
ature anomalies and sea level rise, providing direct evidence that the warming is
caused dominantly by the waste heat. Other extra energies entered the system
also contribute to the warming. Both approaches of using thermodynamic model
and using regression equations can be used for future temperature change fore-
casting.
Sea level rise comes from 1) meltwater, 2) meltwater thermal expansion from
melting point to the average surface seawater temperature, 3) meltwater thermal
expansion due to the surface seawater warming and 4) thermal expansion of
seawaters by the retained heat energy. Using the thermodynamic approach to
forecast future sea level rise is recommended.
Based on these, efficiently fighting global warming needs to control and re-
duce waste heat from human activities. Increasing energy’s effective conversion
efficiency (EECE), rather than only increasing energy efficiency, changing so-
cietal and personal behaviors, and reducing energy consumption through tech-
nology advancements and retrofits, as well as largely developing and prudential-
ly planning the use of surface renewable energies are vital. Recovering and reus-
ing waste heat from the environment will also help greatly mitigate climate
change.
These findings invite the international communities to further review and

re-investigate the real root cause of the current climate change from different
angles: is it GHGs or waste heat or other factors? So that the right, effective and
efficient solutions can be developed.

... Quantification of anthropogenic heat releases has been proposed in the literature but estimates were limited to urban areas or do not involve evaporation mainly because of a lack of data and of the number of factors involved [24][25][26]. Unlike sequential natural heat sources (day not night, in summer more than in winter, in Northern and Southern hemispheres alternatively), many of the anthropogenic heat sources listed above are active almost permanently, a fundamental unfavorable difference in terms of the dynamic of management and elimination of heat. Indeed, periods of low activity of natural warming favor radiative elimination while permanent AHR reduced the efficiency of the elimination process and feed global warming when natural sources do not. ...
... Thermal films on windows, limiting the power of cars, replacing paving stones and bitumen by earth or grass, favoring white surfaces, covering roofs with grass or thatch, favoring woody houses and wooden cladding, improving yields in work and using waste heat as secondary source of energy, etc., are examples of medications against AHR. However, in terms of AHR and justification of an energy transition, the gains brought by these solutions require the quantification from the cradle to the grave as is done for life cycle assessments [26], this for electricity and carbon energies comparatively. ...
... To the main contributions of heat brought discontinuously by natural sources (Sun, volcanoes, forest fires, etc.) are now added anthropogenic contributions, many continuously, due to the undeniable anthropogenic heat released at the production stage of the various energies and when fossil fuels combustion and electricity are used by trains and cars, thermic and nuclear plants, boats, planes and space rockets, missiles and bombs, computers, data storage centers, arsons, phones, garbage burning, etc. Humans, cattle, and hot blood animals are also contributors. Anthropogenic heat is increasingly regarded as sources of environmental heating [10][11][12][13][14][15]. Recently, a quantitative correlation between waste heat and global warming was attempted that included waste heat dispatched between land, ocean, and air. ...

IPCC's predictions of climate deterioration include increases in temperature and in ocean level, as well as local climate events, all attributed to a surplus of carbon dioxide source of radiative forcing that has been building up in the oceans since carbon-based fossil compounds are exploited to generate energy. This mechanism is only consensual and is therefore subject to more and more criticisms without echo because of absence of an alternative mechanism. Selected unusual reasons are first presented to convince non-specialists that greenhouse effect and radiative forcing lack solid scientific basis. As according to physics and thermodynamics, the management of heat inputs in the atmosphere and in the environment must be independent of the source, a recently proposed mechanism based on ice melting and water evaporation is recalled and justified by its extension to distant pass climate fluctuations. Given the major roles attributed to anthropogenic heat releases, in particular waste heat, on the climate, the future depends on the evolution of the anthropogenic/solar heat input ratio. Three scenarios are discussed with respect to reported climate fluctuations for the last 8,000 years of the current interglacial plateau. To position the current times with respect to these scenarios, heat and waste heat generated by the different energy sources and their uses must be assessed from cradle-to-grave to complete the life cycle assessment. With regard to electricity, such assessment must include, for each source, the production mode, in particular for renewable resources, as well as the transport and uses with the aim of increasing efficiency to produce work and minimize waste heat emissions.
... Pandey [19] points out that human intervention through industrialization and deforestation has caused ecological and environmental imbalances, making survival difficult, and global warming is one of the main threats to human survival caused by this imbalance. Bian [20] suggests that waste heat dominates global warming. Wu and Jiang [21] points out that the destruction of the ozone layer, continental storms and Asian brown clouds are the causes of global warming. ...

Background Pursuing GHG reductions by means of all resources and efforts has turned out no result to stop or even slow the global warming: the globe still gets warmer and warmer, especially in the recent years, at record-breaking rate almost each single year. Additionally, no definitive relationship has been found between the warming and the atmospheric GHG concentration. The link between them even in IPCC’s report lacks support and is unconvincing. All these imply that something else is responsible for the warming. On the other hand, huge amount of residual heat or waste heat from human activities has been poured into the climate system but has not been considered seriously in the context of global warming or climate change. Results This article features deploying the basic principles of thermodynamics and applying a new model, Equivalent Climate Change Model, to analyse the currently available data on world energy consumption between 1965 and 2017, and to study the relation between the global warming and the waste heat entered the climate system. The results show that the temperature changes in air, oceans and land are definitively correlated to the respective heat allocated from the waste heat stream based on their specific heat capacities, with high certainty and reliability. The observed anomalies in air fall within a range of simulations at an equivalent climate change surface air boundary layer depth between 50 and 100 m (60 ~ 100 m in recent decades due to more establishments of high-rising heat discharging sources); the anomalies in oceans fall within a range of simulations at an equivalent climate change waters surface boundary layer depth between 0.10 and 0.20 m (0.125 ~ 0.20 m in recent decades); and the anomalies in land fall within a range of simulations at an equivalent climate change land surface boundary layer depth between 0.05 and 0.10 m (0.06 ~ 0.10 m in recent decades). The simulation results at the air layer depth of 70 m are almost the same as NASA’s Lowess smoothing trend. Forecast of future global warming based on this model under the scenario of business as usual indicates that the possible air temperature risings will be in the range of 0.68 ~ 1.13 °C in 2030 and 0.73 ~ 1.22 °C in 2040; the possible sea temperature risings will be in the range of 0.61 ~ 0.98 °C in 2030, 0.66 ~ 1.05 °C in 2040; and the possible land temperature risings will be in the range of 1.02 ~ 1.71 °C in 2030, 1.10 ~ 1.84 °C in 2040. However, if the energy conversion efficiency increased by 10% by 2030 and another 10% by 2040, then the possible air temperature risings would be in the range of 0.54 ~ 0.90 °C in 2030 and 0.44 ~ 0.73 °C in 2040; the possible sea temperature risings would be in the range of 0.49 ~ 0.78 °C in 2030, and 0.40 ~ 0.64 °C in 2040; and the possible land temperature risings would be in the range of 0.81 ~ 1.36 °C in 2030 and 0.66 ~ 1.11 °C in 2040. The observed global average air temperature changes and the Lowess Smoothing values in 2018 and 2019 fall within the range set by the air layer depth between 60 and 100 m, are consistent with the forecast under the scenario of business as usual, further confirms the reliability of this approach. Conclusions Greenhouse gases are not the culprit of the current global warming, instead, huge amount of residual heat or waste heat discharged into the environment from human activities has dominated the warming (beside of solar irradiance and volcano eruptions). Pursuing GHG reductions is bound to be ineffective in preventing the globe from further warming but increases unnecessary burdens. Switching to 100% of surface renewable energies is the ideal solution to completely solve further warming problem. However, geotherm does cause global warming although it is a type of renewable energy. Increasing energy’s conversion efficiency can effectively help slow down the warming, it requires vast investment and will embrace breakthroughs in technologies. Changing human’s behavior individually and socially and retrofitting can decrease the energy consumption and the amount of heat entering the environment and thus help mitigate climate change and its impact in the most cost-effective way. Unlike the General Circulation Models that can only simulate the past air temperature changes with greater uncertainty, the Equivalent Climate Change Model can not only trace the past temperature changes in air, oceans and land, but also can predict the future changes in them, respectively, with high certainty and reliability.

Scrutiny and analysis of various energy applications show that the energy conversion to useful work or new products has been systematically inefficient. The global energy’s total effective conversion efficiency is estimated only about 20% and about 80% of the energy has been discharged into the environment. It is this energy that leads to the unbalance of the climate system’s energy budget balance and causes the global warming. This article presents a simple equivalent climate change model to track the past global warming and to predict the future change trend at the global scale. The model comprises of an equivalent climate change surface air boundary layer, an equivalent climate change land surface boundary layer and an equivalent climate change seawaters surface boundary layer. It produces unique definitive relationships between the temperature changes and the heat entered the air, waters and land. The model can also be used to forecast future non-renewable energy consumption needed to keep the temperature rising under Paris Accord. Analysis of currently available data by using this model confirms that temperature changes in air, seawaters and land closely correlate to the amount of heat discharged into the climate system from human activities. NASA and NOAA’s observations of temperature anomalies for the surface air, sea surface and land surface are well consistent with the temperature changes calculated by this model, especially the calculated results at the depth of 70 meters of the surface air boundary layer and NASA’s Lowess Smoothing trend are very close. Flaring intensifies global warming. Reducing use of fossil fuels, nuclear and geothermal energies, developing surface renewable energies and increasing energy’s total effective conversion efficiency and thus reducing the amount of residual/waste energy are the paths to effectively and efficiently control global warming.

Significant changes in the state of the Arctic ice cover are occurring. As the summertime extent of sea ice diminishes, the Arctic is increasingly characterized by first-year rather than multi-year ice. It is during the early stages of ice growth that most brine is injected into the oceans, contributing to the buoyancy flux that mediates the thermo-haline circulation. Current operational sea-ice components of climate models often treat brine rejection between sea ice and the ocean similarly to a thermodynamic segregation process, assigning a fixed salinity to the sea ice, typical of multi-year ice. However, brine rejection is a dynamical, buoyancy-driven process and the salinity of sea ice varies significantly during the first growth season. As a result, current operational models may over predict the early brine fluxes from newly formed sea ice, which may have consequences for coupled simulations of the polar oceans. Improvements both in computational power and our understanding of the processes involved have led to the emergence of a new class of sea-ice models that treat brine rejection dynamically and should enhance predictions of the buoyancy forcing of the oceans. © 2015 The Author(s) Published by the Royal Society.

Many of the processes that make sea ice such an important aspect of the polar oceans occur at small scales, ranging from the sub-millimetre to the metre scale. An understanding of how large-scale behaviour of sea ice monitored by satellite relates to and depends on the processes driving ice growth and decay requires an understanding of the evolution of ice structure and properties at these finer scales & is the subject of this chapter. This chapter gives an introduction and overview of fundamental processes of sea ice, focussing on un-deformed first-year ice.

During the initial freezing of the tropical ocean on Snowball Earth, the first ice to form would be sea ice, which contains salt within inclusions of liquid brine. At temperatures below −23°C, significant amounts of the salt begin to crystallize, with the most abundant salt being hydrohalite (NaCl·2H2O.) These crystals scatter light, increasing the ice albedo. In this paper we present field measurements of the albedo of cold sea ice and laboratory measurements of hydrohalite precipitation.Precipitation of salt within brine inclusions was observed on windswept bare ice of McMurdo Sound at the coast of Antarctica (78°S) in early austral spring. Salinity and temperature were measured in ice cores. Spectral albedo was measured on several occasions during September and October. The albedo showed a gradual increase with decreasing temperature, consistent with salt precipitation.Laboratory examination of thin sections from the ice cores showed that the precipitation process exhibits hysteresis, with hydrohalite precipitating over a range of temperatures between −28°C and −35°C but dissolving at about −23°C. The causes of the hysteresis were investigated in experiments on laboratory-grown sea ice with different solute mixtures. All mixtures showed hysteresis, suggesting that it may be an inherent property of hydrohalite precipitation within brine inclusions rather than being due to biological macromolecules or interactions between various salts in seawater.

Solar irradiance reconstructions back to 1874 are used to estimate the effect of the Sun on global-mean temperature. The importance of the history effect of the Sun on global-mean temperature. The importance of the history effect, whereby recent temperature changes may be influenced significantly by past forcing changes, is evaluated. Modelled temperature changes are shown to be relatively insensitive to model uncertainties. The overall range of modelled temperature variations is extremely small, 0.05C.
