The Upper Atmosphere Is Cooling, Prompting New Climate Concerns

Yale E360

A new study reaffirming that global climate change is human-made also found the upper atmosphere is cooling dramatically because of rising CO2 levels. Scientists are worried about the effect this cooling could have on orbiting satellites, the ozone layer, and Earth’s weather. Read more on E360 →

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?

Some new CMIP6 MSU comparisons

Real Climate

This ensemble samples model structural variability (vertical resolution, model top, interactive composition) and some aspects of forcing uncertainty (notably for aerosols and ozone), as well as the initial-condition (‘weather’) variability we are used to seeing. As above, the GISS ensemble diverges slightly from the observations.

EPA's GreenChill Program Recognizes Environmentally Friendly Refrigerant Management In Supermarket Industry, Including Weis Markets, The Giant Company, ALDI In PA

PA Environment Daily

Environmental Protection Agency’s GreenChill Program recognized 12 food retail companies and one manufacturer of advanced refrigeration systems for their exceptional achievements to reduce the use of ozone-depleting substances and/or climate-damaging refrigerants.

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.

The CO2 problem in six easy steps (2022 Update)

Real Climate

The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium. in IPCC TAR).
