Excerpt: Climate sensitivity to future increases in CO2 concentration is calculated to be 0.50K, including the positive feedback effects of H2O, while climate sensitivities to CH4 and N2O are almost undetectable at 0.06K and 0.08K respectively. This result strongly suggests that increasing levels of CO2 will not lead to significant changes in earth temperature and that increases in CH4 and N2O will have very little discernable impact...This is an unfortunate situation since world governments are implementing ambitious and expensive plans to limit the increase of global temperatures by reduction of CO2 emissions to atmosphere, and to achieve a net zero carbon economy, in the belief that CO2 emissions are the main driver of global temperature increases...

An increase in average Relative Humidity of 1% will result in a temperature increase of 0.03Kelvin. By comparison, CO2 is a bit player.

Dr. Curry: "Climate change is a grand narrative in which manmade climate change has become the dominant cause of societal problems. Everything that goes wrong reinforces the conviction that there is only one thing we can do to prevent societal problems – stop burning fossil fuels." ...

"According to the IPCC, there is not yet evidence of changes in the global frequency or intensity of hurricanes, droughts, floods or wildfires.  In the U.S., the states with by far the largest population growth are Florida and Texas, which are warm, southern states.  Property along the coast is skyrocketing in value.  Personal preference and market value do not yet regard global warming as ‘dangerous.’"

The researchers find that the current levels of atmospheric CO₂ and water vapor are close to saturation. Saturation is a technical term meaning that the greenhouse effect has already had its maximum impact and further increases in concentration will cause little additional warming.
