Legal Planet

To recap: The unanimous opinion found that nations of the world have a legal obligation to limit their emissions of greenhouse gases or else pay reparations for the harms of climate change. Mackintosh has closely followed the case which was first filed in 2018 by Vanuatu, an archipelago in the Pacific Ocean.

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.

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. mm increase every year.

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.
