New AGU Presentation: ‘No Increase In Earth’s Surface Temperature From Increase In CO2’

At next month’s American Geophysical Union (AGU) Fall Meeting in New Orleans (US), an independent researcher named Trevor Underwood will be presenting an equation-rich analysis that thoughtfully undermines the perspective that increases in CO2 concentrations are a fundamental variable affecting climate.

Instead, Underwood argues that the absorption band where CO2 emissivity could have an effect is likely already saturated, precluding the capacity of increased CO2 concentrations to produce atmospheric warming.
He also advances the position that solar irradiance changes can explain modern temperature variations, which is consistent with other recent analyses. http://notrickszone.com/2017/11/09/...o-solar-forcing-not-co2/#sthash.6QrOY1IE.dpbs

It seems that more and more of these papers questioning the “consensus” view on the efficacy of the CO2 within the greenhouse effect are being considered in scientific circles. Several previous examples are listed below.

The volume of contrarian analyses would seem to suggest that the climate’s specific sensitivity to CO2 concentration changes is not yet settled.

And so the debate rages on....

WASHINGTON, DC The American Geophysical Union today released a revised version of its position statement on climate change. Titled Human-induced Climate Change Requires Urgent Action, the statement declares that humanity is the major influence on the global climate change observed over the past 50 years and that rapid societal responses can significantly lessen negative outcomes. AGU develops position statements to provide scientific expertise on significant policy issues related to Earth and space science. These statements are limited to positions that are within the range of available geophysical data or norms of legitimate scientific debate.
