New misguided interpretations of the greenhouse effect from William Kininmonth

Real Climate

Another clue is William Kininmonth’s ‘rethink’ on the greenhouse effect for The Global Warming Policy Foundation. When looking at the effect of changes in greenhouse gases, one must look at how their forcing corresponds to the energy balance at the top of the atmosphere.

The CO2 problem in six easy steps (2022 Update)

Real Climate

Step 1: There is a natural greenhouse effect. This means that there is an upward surface flux of IR around (~398 W/m 2 ), while the outward flux at the top of the atmosphere (TOA) is roughly equivalent to the net solar radiation absorbed (~240 W/m 2 ). Step 2: Trace gases contribute to the natural greenhouse effect.

60 Scientists Call for Accelerated Research Into ‘Solar Radiation Management’ That Could Temporarily Mask Global Warming

Inside Climate News

Their public letter comes after an even larger group of scientists and academics called for a strict ban on such “geoengineering,” saying it could divert attention and resources from needed greenhouse gas cuts.

Glossary of Greenhouse Gas Terms

Greenbuilding Law

With proposed federal regulation of greenhouse gas emissions by the Securities and Exchange Commission requiring GHG disclosure and new state statutes, including a new Maryland law that requires not only disclosure, but also a mandated reduction in GHG emissions, a greater appreciation of the subject of GHG appears in order.

Science denial is still an issue ahead of COP28

Real Climate

It is 33 years now since the IPCC in its first report in 1990 concluded that it is “certain” that greenhouse gas emissions from human activities “will enhance the greenhouse effect, resulting on average in an additional warming of the Earth’s surface.”

The definitive CO2/CH4 comparison post

Real Climate

So this is an attempt to put all of that in context and provide a hopefully comprehensive guide to how, when, and why to properly compare the two greenhouse gases. You might recall that GWP is defined as the ratio on per-kg basis of the temperature impact of other greenhouse gases compared to CO 2 over a specific time period.

CMIP6: Not-so-sudden stratospheric cooling

Real Climate

That means the greenhouse substances are basically just CO2 and ozone, and they absorb in quite different parts of the spectrum. In the band of radiation where CO2 absorbs a lot (~15 $mu$m), increasing CO2 levels in the troposphere make it ever harder for those photons to get to the stratosphere or above.
