CMIP6: Not-so-sudden stratospheric cooling

Real Climate

So SSU me Like MSU trends, these records reflected a weighted average of atmospheric temperatures, and the three SSU channels progressively weight higher levels in the stratosphere, roughly centered on 30km, 40km and 45km above the surface but with quite a bit of overlap. 9919-9933, 2018.

News Flash! International Cooperation on the Environment Remains Possible

Law and Environment

Today, the New York Times reported that a recent assessment shows that the world is on track to reach pre-1980 levels of upper atmosphere ozone by roughly 2040. That is in spite of the discovery in 2018 of “rogue” use of chlorofluorocarbons, probably from factories in China.

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

Another clue indicating a shortcoming is if you look at the atmospheric CO 2 -concentrations over time to see how much impact the IPCC reports have had on the real policy-makers in the world (Figure below). The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.

From Research to Action: The Growing Impact of Attribution Science

Union of Concerned Scientists

A study of a 2018 South African drought found that climate change made it three times more likely. This research determines the relative contributions of different emission sources, including the oil and gas, agricultural, industrial, and transportation sectors, to the overall increase in heat-trapping gas concentrations in the atmosphere.
