Abstract

Since 1950 CO2 has been increasing at least 100 times faster and has risen 32% greater than in the prior 800,000 years. C02 is currently higher than it has been in 15 million years. The recent CO2 increase was directly measured by instruments and the 800,000 year old values were directly measured from air bubbles trapped in columns of ice.
Proving severe anthropogenic climate change
Since 1950 CO2 has been increasing at least 100 times faster and has risen 32% greater than
in the prior 800,000 years. C02 is currently higher than it has been in 15 million years.
The recent CO2 increase was directly measured by instruments and the 800,000 year old
values were directly measured from air bubbles trapped in columns of ice.
"Based on the best historical data that we have available CO2 is probably increasing at a rate
at of least 100 times faster than at any time in the last 800,000 years."
Pieter Tans (lead scientist of NOAA's Global Greenhouse Gas Reference Network)
CO2 emissions are precisely correlated to rise in atmospheric CO2 which is very
strongly correlated to increases in global temperature for 800,000 years.

CO2 levels are very highly correlated to global temperature for 800,000 years.

When we look at the most reliable geological data we see that global CO2 has not been as
high as it is now for nearly 15 million years.

According to the Shakun et al. data, approximately 7% of the overall glacial-interglacial global
temperature increase occurred before the CO2 rise, whereas 93% of the global warming
followed the CO2 increase.

The average rate of increase CO2 since 1950 of 1.43 PPM per year is 113 times faster
than the next fastest rate in ALL climatological data: 0.0127 PPM per year.
This is the most granular ice core air bubble CO2 data available
the oldest 500 years of data has CO2 air samples that vary by only 40 years
The newest data is much more precise because it is directly measured by instruments in Hawaii.

The following data shows that the time frames of the air samples are very short providing great precision.

CO2 increasing much faster than ever before and its rate of increase is also increasing.
