The UN's IPCC and its coterie of green-sharia "scientists" have long pursued a political agenda that requires all climate change and global warming to be a result of human CO2 emissions, and in addition, any solar impact on temperatures is absolutely minimal - yet, the empirical evidence does not support said political agenda, including the BEST maximum temperature dataset

Read here. The IPCC's catastrophic anthropogenic global warming (CAGW) alarmists have long predicted that increasing CO2 levels will directly cause global warming to reach anywhere from 3 to 10 degrees Celsius higher in the near future. In essence the world's maximum temperatures are being exclusively driven to dangerous heights by CO2.
But is that actually happening?
The most recent empirical evidence clearly indicates that CO2 levels are not driving the average atmospheric, global and/or ocean temperatures dangerously higher. And now comes an analysis of the BEST temperature dataset, which confirms the weak driving force that CO2 appears to be.
This graph has monthly atmospheric CO2 levels superimposed onto plots of the BEST maximum temperatures for the U.S. and a solar activity proxy (i.e. Total Solar Irradiance). The blue maximum temperature plot is in sync (up and down) with the red solar activity curve. Obviously, the ever incessant rise of CO2 levels is not in sync with the up and down movements of temperature variation.
"Recent work by NCAR senior scientists Drs. Harry van Loon and Gerald Meehl has also emphasized a physical relationship between incoming solar radiation and temperature. These scientists argue indirectly that, in testing for this relationship, daytime maximum temperature is the most appropriate criterion to use to characterize the temperature. This measure is available for the US from the BEST data set...The reconfirmation now of a strong sun-temperature relation based specifically upon the daytime temperature maxima adds strong and independent scientific weight to the reality of the sun-temperature connection...This suggests strongly that changes in solar radiation drive temperature variations on at least a hemispheric scale...Close correlations like these simply do not exist for temperature and changing atmospheric CO2 concentration."
