A new study finds that a substantial chunk of summer sea ice loss in recent decades was due to natural variability in the atmosphere over the Arctic Ocean. The study, from the University of Washington, the University of California Santa Barbara and federal scientists, is published in Nature Climate Change.

UCLA and Lawrence Livermore researchers have found that most climate models overestimate the increase in global precipitation due to climate change. Because this acts as such a strong lever on global precipitation changes, the models are likely overestimating the increase in global precipitation with global warming.
