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. Thompson et al. We are using the NOAA-STAR version 3.0 of these products (Zou et al.,

Phantastic Job!

Real Climate

There was a workshop in 2018 (that I attended) to discuss how one might go about doing something better – updating the data, improving quality control, and using models to better connect local or regional signals to the global means. and, like many of us, had found the then-current literature somewhat unsatisfactory. 0.6ºC (95% CI).

Fortunately, Manabe recently wrote a retrospective on his early work in response to receiving the Crafoord prize in 2018. 2018 ), but I think it’s fair to say that few modelers think it’s a useful tool anymore. In his 2018 retrospective, Manabe doesn’t discuss the issue at all. 9335-9350, 2018.

Getting physical with the climate crisis

Physics World

Extreme heat is not just an abstract notion: if we can’t cool our bodies enough, we’re in danger of neurological failure, organ failure and even death, with the risks highest for children and the elderly. On balance, clouds nearer the stratosphere warm us, whereas low-lying clouds tend to cool us because their greenhouse effect is smaller.

Antarctic extreme events: ‘All-time records are being shattered not from decades ago, but from the last few years and months’

Frontiers

For example, Antarctica acts to cool our planet by reflecting solar radiation back to space by virtue of the brightness of its snow surface. In the ocean, 19 marine heatwaves have been recorded between 2002 and 2018. In the Arctic this has led to regional warming four times faster than the global average.
