Groundwater makes up 30 to 50 percent of California’s water supply, but until recently there were few restrictions placed on its retrieval. Then in 2014 California became the last Western state to require regulation of its groundwater. With deadlines starting this year, for the first time water managers in the nation’s premier agricultural region – the state’s Central Valley – are tasked with estimating available groundwater. It’s a daunting technological challenge.

The image of huge chunks of ice breaking away from glaciers and ice sheets, then floating out to sea in Earth’s most remote places, may be the most iconic symbol of a warming planet. And while most people will never see these familiar phenomena up close, what’s happening within some of the iciest settings still affects people and regions thousands of miles away.

Ecologist Heidi Steltzer, a Fort Lewis College professor and member of the Department of Energy’s Watershed Function Scientific Focus Area (SFA) project led by Lawrence Berkeley National Laboratory, studies how reduced snowpack and earlier snowmelt caused by climate change impact water supply in high-mountain areas..

Tiny Toxins: How Algal Blooms Affect Coastal Systems Through A Complex Web Of Interactions

Think summertime and the mind usually wanders to warm thoughts of sand, sunscreen, and fireworks. But increasingly summertime fun is being interrupted by algal blooms. From the Atlantic seaboard to the Gulf of Mexico, from the Great Lakes to the Pacific coast, harmful algal blooms are shutting down beaches, killing fish, birds, and other wildlife, and contaminating drinking water. The economic impacts of an algal bloom can be severe, especially if the algae become toxic.
