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? How well do the models do?

Climate Change Threatens Already Poor Air Quality in California’s Central Valley

Union of Concerned Scientists

California’s Central Valley consistently experiences the country’s worst air quality, and climate change is poised to make air quality even worse. In a region known for its exceptional agricultural productivity, climate change is quickly amplifying a dangerous type of climate risk in California’s Central Valley: air pollution.

Climate Change and Me

Academy of Natural Sciences

The first climate change presentation I saw was back in the 1970s when I was working for the National Weather Service. Murray Mitchell, was the top climate scientist for NWS. While that got the bulk of the publicity, Dr. Mitchell assured us that the warming of the climate would be the biggest problem in the future.

This Climate Debate is a lot of Hot Air

Legal Planet

We’ve been hearing a lot lately about geoengineering – the various scientific theories and governance ideas that could eventually lead to technological interventions to help cool the planet. Take this recent CNN story titled “Supporters of a controversial climate solution say it could be key. Anyone can float a balloon.

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

I followed with great interest the launch of the sixth assessment report Working Group 1 (The Physical Science Basis) from the Intergovernmental Panel on Climate Change (IPCC) on August 9th. In addition, ozone depletion higher up in the stratosphere has caused a cooling high up in the atmosphere.
