Clouds and Climate Change
Prof. Tom Choularton, Centre for Atmospheric Science, University of Manchester
Cloud feedbacks are a fundamental and persistent problem in climate science and are the dominant uncertainty in assessing global and regional climate sensitivity. The talk will begin with an overview of what is known about clouds and climate based on the 2013 IPCC 5 th Assessment report. There will then be a discussion of some recent projects designed to increase our understanding and produce better treatments of clouds in Global Models. The projects described will address issues concerning warm (liquid clouds) and mixed phase or ice clouds. Finally it has recently been proposed that cloud seeding can be a possible method of geoengineering to reduce the effects of increasing greenhouse gases. These ideas will be discussed.
