This publication introduces two parameters related to cumulative CO2 emissions. The first parameter is "Velocity of Change in Cumulative CO2 Emissions", VCCO2. This parameter represents an average annual change in cumulative CO2 emissions and is expressed in ton of CO2 per year. The second parameter is "Acceleration of Change in Cumulative CO2 Emissions, ACCO2, and is expressed in ton of CO2 per year, per year (tCCO2/y 2). These two parameters are in addition to the parameter "Global Warming Rate", GWR [°C/y], and "Global Warming Acceleration", GWA [°C/y 2 ], described in the previous publication. The velocity of change in cumulative CO2 emissions, VCCO2, is +35.33 GtCCO2/y in the last 11 years, the acceleration of change in cumulative CO2 emissions, ACCO2, is +0.559 GtCCO2/y 2 in the last 31 years, and the minimum increase of ACCO2, is +1.2%/y.

This publication includes details regarding the online converter of global warming baselines "Global Warming Online Baselines Converter, °C" available on the Internet site nowagreen.com/globalwarming. This converter displays the conversion factor from any period to any period in the range 1850-2021 for land+ocean, 1880-2021 for ocean-only, or 1750-2021 for land-only.

Changes in this version: added original baselines data, added formula for conversion from the original baseline to 1850-1900 baseline, including relevant conversion factor.

Global warming datasets converted to the uniform baseline. NASA, NOAA and Berkeley Earth datasets of global surface temperature changes in the period 1850-2021 for land+ocean, 1750-2021 for land only and 1880-2021 for ocean only, converted to the 1850-1900 baseline.
This publication includes global warming databases converted to the uniform baseline. The publication includes NASA, NOAA and Berkeley Earth databases of global surface temperature changes in the period 1850-2021 for land+ocean, 1750-2021 for land only and 1880-2021 for ocean only. The databases are converted to the 1850-1900 baseline showing minor differences between them. 61 years linear trendlines indicate constant increase of global warming reaching in 2021 0.017 °C/y for land+ocean, 0.026 °C/y for land only, and 0.012 °C/y for ocean only.
This publication analyzes changes of global warming rates (GWR) expressed in Centigrade per year (°C/y) and introduces a parameter “global warming acceleration” (GWA) expressed in Centigrade per year per year (°C/y2). GWA may be applied for prediction of the GWR for the next decade. If the current decrease of GWA will continue for the next 11 years, Global Warming Rate will increase from the current +0.017 °C/y to +0.019 °C/y, for land+ocean.

This publication includes a conversion table between various baselines of global surface temperature changes. The conversion factor from 1951-1980 to 1850-1900 baseline is +0.31°C for land+ocean, +0.49°C for land only, and +0.29°C for ocean only. Glossary Ave average BL baseline CF conversion factor between baselines or reference periods DB dataset, database Units The temperature change unit in this work is °C.
Annual averages of global surface temperature changes for land only based on Berkeley Earth monthly dataset above the 1951-1980 baseline. The dataset is from 1750 in °C, 3 decimal places.

Two completely different monitoring systems were applied to analyze annual air temperature differences. The first monitoring system for analysis of changes in air temperature in Jerusalem is a meteorological station at Jerusalem University. The second monitoring system for analysis of surface temperature changes globally and locally in Israel is applied by NASA and further analyzed and detailed by FAOSTAT. Both monitoring systems indicate an average temperature increase since the starting year of the Jerusalem database, 1993.
