Proving the Reality of Global Warming When we look at 800,000 year ice core data CO2 levels since 1950 have risen at a rate of 123-fold faster than the fastest rate in 800,000 years. When we see that this rise is precisely correlated with global carbon emissions the human link to climate change seems certain and any rebuttal becomes ridiculously implausible. The 800,000 year correlation between CO2 and global temperatures seems to be predicting at least 9 degrees C of more warming based on current CO2 levels. CO2 emissions precisely correlated to rise in atmospheric CO2 which is very strongly correlated to increases in global temperature CO2 levels are very highly correlated to global temperature for 800,000 years. http://theconversation.com/the-three-minute-story-of-800-000-years-of-climate-change-with-asting-in-the-tail-73368 Fastest rate of increase in CO2 levels measured as 97 PPM per 8,330 years beginning 340,817 years ago.
