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
A key challenge in climate science is to distinguish temperature changes in response to external forcing (e.g., global warming in response to anthropogenic greenhouse gasses)
In a previous post, I described the concept of emergent constraints, which allow us to narrow uncertainties in climate change projections through empirical relationships that
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
The weakening of the Walker circulation in the tropical Pacific is a robust response to global warming in climate models. This can have a global
In a recent article in JAMES (Pressel et al., 2017), we explore how numerical error and subgrid-scale modeling in LES interact to determine the quality
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
