Climate models have falsely assumed a (strong) cloud brightening cooling feedback, researchers of Yale University (Ivy Tan & Trude Storelvmo) and the Lawrence Livermore National Laboratory (Mark Zelinka) write in Science. Refining cloud behaviour in a warming atmosphere leads to … Continue reading →
We could say clouds are too complicated for climate science – and ignore them forever. We could also just try to incorporate them in the models. If you do, chance is you’ll find climate sensitivity is underestimated, a very interesting … Continue reading →
As a regular you will be well aware that some clouds cool the climate and other clouds warm. Determining the exact balance of the cloud-climate feedback will help decrease uncertainty margins for 21st century warming forecasts. Unfortunately it’s a complicated … Continue reading →
Clouds have a profound effect on the climate, but we know surprisingly little about how they form. Erika Sundén has studied how extremely small cloud particles can dispose of excess energy. This knowledge is necessary to understand processes in the atmosphere that affect global climate change.
Says an international research group led by Gothenburg University. It serves to show individual climate sensitivity studies are never conclusive but add up bits of fresh understanding to an already enormous pile of data and knowledge.
The mainstream and long-held view of clouds in relation to climate change is that clouds are acting as a feedback in response to temperature changes caused by human activity. Some sceptics however argue that it is the other way around … Continue reading →
Clouds can have a large impact on global climate. Depending on conditions they can either trap or reflect the sun’s heat. Scientists at CERN have now determined that organic vapours released by Earth’s organisms play a far more significant role … Continue reading →
