Atmospheric rivers getting warmer along U.S. West Coast

Most of the West Coast of the United States relies on a healthy winter snowpack to provide water through the dry summer months. But when precipitation falls as rain rather than snow, it can diminish summer water supplies, as well as trigger floods and landslides. A new study in AGU’s Journal of Geophysical Research: Atmospheres finds atmospheric rivers –plumes of moisture that deliver much of the west’s precipitation—have gotten warmer over the past 36 years.

Could “cocktail geoengineering” save the climate?

Geoengineering is a catch-all term that refers to various theoretical ideas for altering Earth’s energy balance to combat climate change. New research from an international team of atmospheric scientists published by Geophysical Research Lettersinvestigates for the first time the possibility of using a “cocktail” of geoengineering tools to reduce changes in both temperature and precipitation caused by atmospheric greenhouse gases. Carbon dioxide emissions from the burning of coal, oil, and gas …
