Polar regions warm faster than the rest of the world. This is happening now, and also happened millions of years ago when alligators and turtles used to live in the Arctic. But most climate models are not able to produce the observed warming. Why?

The good news is that these clouds were more likely to form in the past than they will be in the future. This is due to stratospheric circulation patterns that depend on the location of continents and mountains. 6/6.

Including these clouds in climate models would therefore reduce the gap between models and climate reconstructions in the past. It might also improve our future projections. 5/6

We find that for high methane concentrations these clouds result in a radiative forcing larger than the direct greenhouse effect from the methane itself. 4/6

The role of these clouds was first hypothesized by Lisa Sloan in the early 90s. Now we have atmosphere models complex enough to test her theory. We find that for high enough greenhouse gas concentrations, these clouds could cause additional warming at the poles of over 7C. 3/6.

Our research in @NatureGeosci shows that a special type of cloud might be the reason why. They are called Polar Stratospheric Clouds. They are rare today but might become more prominent with higher GHG concentrations. They keep the surface warm, even during polar night. 2/6.

The green Sahara: why and when did the Sahara transition between a wet state, supporting river systems and vegetation, and a desert as we know it today? This new paper shows it was a combination of slow changes in solar insolation and abrupt changes in ocean circulation.
