The fifth Intergovernmental Panel on Climate Change (IPCC) report states with 95 percent confidence that humans are the main cause of the current global warming. Many media outlets have reported that this is an increase from the 90 percent certainty in the fourth IPCC report, but actually the change is much more significant than that. In fact, if you look closely, the IPCC says that humans have most likely caused all of the global warming over the past 60 years.
Why is the IPCC AR5 so much more confident in human-caused global warming?
I have to agree with the Nutter about this. Data tampering by government climate scientists is likely responsible for 100% of the warming shown in their graphs since 1940.
Temperatures were much hotter during the 1930s
