When President Shitstain's Nominees Speak, Remember: Humans Driving 100% Of Warming Since 1951

The latest Intergovernmental Panel on Climate Change (IPCC) report – which summarizes the latest and greatest climate science research – was quite clear that humans are responsible for global warming:

It is extremely likely [95 percent confidence] more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic increase in greenhouse gas concentrations and other anthropogenic forcings together … The best estimate of the human-induced contribution to warming is similar to the observed warming over this period … The contribution from natural forcings is likely to be in the range of ?0.1°C to 0.1°C, and from internal variability is likely to be in the range of ?0.1°C to 0.1°C.

In fact, the report’s best estimate was that humans are responsible for all of the global warming since 1951, and greenhouse gases for about 140%. That’s because natural factors have had roughly zero net effect on temperatures during that time, and other human pollutants have had a significant cooling effect. In other words, the Earth’s surface warmed about 0.65°C between 1951 and 2010. Human greenhouse gas emissions caused temperatures to be about 0.9°C hotter than they would have otherwise been. But other human pollutants caused about 0.25°C cooling, and natural factors had a very small effect.

EDIT

This expert conclusion is quite different from the comments of Trump’s cabinet nominees, who were all very consistent in admitting that there is “some connectivity,” as Trump put it, between human activity and global warming, but claimed that the degree of human influence remains open for debate.
