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.

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.

    Plants need CO2 just as much as they need water and a little TLC and we need CO2 for plants for crops and to make little snowflakes whine

    There are a whole bunch of people meeting in Bonn Germany who need to know the information in this article. The problem is that they don’t want to know.
