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. So the net effect is less absorption and more emittence, and thus they give a cooling.

How not to science

Real Climate

McNider and Christy, Feb 19th 2014, Wall Street Journal Most of the op-ed is a rather tired rehash of faux outrage based on a comment made by John Kerry (the then Secretary of State) and we can skip right past that. Remember ‘satellite cooling’?]. The version of the MSU2R product at the beginning of 2014 was version 5.5,

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air. Carbon dioxide (CO 2 ) is the most important greenhouse gas that we have added to the atmosphere, however, some of it has been absorbed by land and oceans.

Phantastic Job!

Real Climate

It is not as though people have not tried – we discussed this here in 2014, where we made a plea for better graphs of the global temperature. All of which adds to the uncertainty. Now, 10 years later, we finally have something. The first factor increases the apparent sensitivity, and the second decreases it.

Disinformation Alert: Fossil Fuel Interests Preparing to Deploy False Claims about New EPA Rules

Union of Concerned Scientists

After the EPA proposed the Clean Power Plan in 2014, for example, fossil fuel interests and their backers tried to argue that the proposal’s 2030 emission-reduction targets were completely unrealistic, and that the country would see astronomically high costs and blackouts due to the rule.
