The first issue is your source. PragerU is not a credible source. I have no issues with Richard Lindzen, other than appearing in a YouTube video that has no credibility. Which in return damages his credibility. He would have been better served to simply make the video under his own name.
The second issue is his "Group 1" in which he claims are "scientists with the
International Panel on Climate Change." When in reality it it is
Intergovernmental Panel on Climate Change and consists entirely of politicians, not scientists.
The third issue is the amount of temperature change since 1880. According to NASA's GISS data the mean temperature increase between 1880 and 2011 is only 0.51°C (0.936°F) which is half of what he is claiming because he is getting his misinformation from the extremely leftist and highly political IPCC.
