Cloudy feedback on global warming

Lawrence Livermore National Laboratory researchers have identified a mechanism that causes low clouds -- and their influence on Earth’s energy balance -- to respond differently to global warming, depending on their spatial pattern and location. The results imply that studies relying solely on recent observed trends underestimated how much Earth will warm due to increased carbon dioxide...

Climate scientist aims to clear the air on clouds

Mark Zelinka has his head in the clouds.The researcher in the Program for Climate Model Diagnosis and Intercomparison is delving into research on how climate change affects cloud properties and vice versa.Using detailed data from satellites and climate models, Zelinka, who was recently converted from a postdoc to staff scientist, examines the vertical structure and optical properties of...
