Rising greenhouse gases have cooling effect on Antarctica’s atmosphere

New Scientist

A "negative greenhouse effect" means rising concentrations of CO2 and methane have slightly cooled parts of Antarctica’s upper atmosphere, but that could change as the air becomes more humid

CMIP6: Not-so-sudden stratospheric cooling

Real Climate

As predicted in 1967 by Manabe and Wetherald , the stratosphere has been cooling. The dominant factors are changes in CO2 (a cooling), ozone depletion (a cooling), warming from big volcanoes, and oscillations related to the solar cycle. But why is the stratosphere increasingly chill? The basic concept is easy to grasp though.

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.” It’s not hard to understand. Gray areas show lack of data.

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.

A Dangerous Disruption

First, the cooling from the reflective materials they will inject, for which they are already selling carbon credits, charging $10 per gram of SO 2 released (!) Pinatubo, widely used as an analogy for SAI, put about 15M tons of sulfur aerosols in the stratosphere and cooled the Earth a little less than 1°C over the following year.
