Fifty years ago today, millions gathered in demonstrations, teach-ins, and community-cleanups, with words and deeds demanding a more sustainable future. The first Earth Day marked the
There are several questions that have been asked frequently about our recent paper in Nature Geoscience. There is a blog post with answers to some of
Climate projections continue to be marred by large uncertainties, which originate in processes that need to be parameterized in models, such as clouds, turbulence, and ecosystems. But
Various attempts have been made to narrow the likely range of the equilibrium climate sensitivity (ECS) through exploitation of “emergent constraints.” They generally use correlations between
How much does a cloud weigh? That was the question Karen LaMonte asked us in an email a year and a half ago. LaMonte—an artist who
Last Friday, on the eve of Earth day, Congressman Adam Schiff hosted a town hall on climate change at Caltech. Schiff and Francesca Hopkins from
How low clouds respond to warming remains the greatest source of uncertainty in climate projections. Climate models projecting that much less sunlight will be reflected
We are organizing a summer school for graduate students and early career scientists on Fundamental Aspects of turbulent flows in climate dynamics, to take place
Through their reflection of sunlight and absorption/re-emission of thermal radiation, clouds regulate Earth’s energy balance. But it remains uncertain, in particular, how the fraction of
