    The stability of the Antarctic Peninsula’s largest ice shelf may depend upon stripes of extremely strong ice running down its spine, a new study finds.

    A new study from researchers at UCLA and the University of Houston reveals estimates of significant groundwater loss in California’s Central Valley during the recent drought and sparks questions of sustainability for the important agricultural area.

    A growing number of wildfire-burned areas throughout the western United States are expected to increase soil erosion rates within watersheds, causing more sediment to be present in downstream rivers and reservoirs, according to a new study.

    Groundwater recharge in the Western U.S. will change as the climate warms--the dry southern regions will have less and the northern regions will have more, according to new research.

    Freshwater streams and rivers naturally clean up some forms of pollution originating from urban and agricultural areas, but increased storm intensity reduces this ability.

    Scientists have developed cartograms — maps that convey information by contorting areas — to visualize the risks of climate change in a novel way.

    A new study has found that dust, not spring warmth, controls the pace of spring snowmelt that feeds the headwaters of the Colorado River.

    The flow of water that supports hydro-electric and irrigation infrastructure in the mountain regions of Nepal and India is regulated by hundreds of large icy ponds on the surface of some of the world’s highest glaciers, scientists have revealed.

    The 2008 Wenchuan earthquake in Sichuan, China killed tens of thousands of people and left millions homeless. Approximately 20,000 deaths -- nearly 30 percent of the total -- resulted not from the ground shaking itself but from landslides the quake triggered. A new model can help experts address such risks by estimating the likelihood of landslides that will be caused by earthquakes anywhere in the world. The estimates can be available within minutes, providing potentially life-saving information to people who are affected by earthquakes and the agencies and organizations charged with responding to them.

    Seasonal snow and ice accumulation cause glaciers in the Cascade Range mountains to grow a little every winter and melt a little every summer. This annual melt provides water for much of the Pacific Northwest, which includes Washington, Oregon, Idaho and parts of Montana. Inhabitants of the region utilize this water for drinking, crop irrigation, generating hydroelectric power and other uses. Glacier melt provides supplementary water when less snowmelt is available, alleviating drought conditions or other impacts of dry periods.
