Sand Dunes on the Loose Due to Climate Change

corecast@usgs.gov (U.S. Geological Survey - CoreCast Team) — Mon, 4 May 2009 12:34:29 UTC

Climate change is increasing the mobility of sand dunes in the Southwest, posing threats to roadways, infrastructure, human health, cultural practices of the Navajo Nation, and much more. Vegetation on dunes serves as a stabilizer, but as the climate warms and precipitation decreases, there is less vegetation growth.

USGS scientist Margaret Hiza and intern Leanna Begay discuss their research to understand the dunes' plant diversity and what changes are occurring.

Contaminants in 20 Percent of U.S. Private Wells

corecast@usgs.gov (U.S. Geological Survey - CoreCast Team) — Thu, 26 Mar 2009 17:27:31 UTC

More than 20 percent of private, domestic wells contain at least one contaminant at levels of potential health concern. About 43 million people—or 15 percent of the Nation's population—use drinking water from private wells, which are not regulated by the Federal Safe Drinking Water Act.

USGS scientist Leslie Desimone discusses the new study, the contaminants found, and the implications for society.

Can We Move Carbon from the Atmosphere and into Rocks?

corecast@usgs.gov (U.S. Geological Survey - CoreCast Team) — Mon, 23 Mar 2009 15:10:14 UTC

A new method to assess the Nation's potential for storing carbon dioxide in rocks below the earth's surface could help lessen climate change impacts. The injection and storage of liquid carbon dioxide into subsurface rocks is known as geologic carbon sequestration.

USGS scientist Robert Burruss discusses this new methodology and how it can help mitigate climate change.

Hazard Roundup--February 2009

corecast@usgs.gov (U.S. Geological Survey - CoreCast Team) — Thu, 19 Mar 2009 20:04:26 UTC

Slight Climate Changes May Trigger Abrupt Ecosystem Responses

corecast@usgs.gov (U.S. Geological Survey - CoreCast Team) — Mon, 16 Mar 2009 15:17:48 UTC

This is the third and final installment of a three-part series on climate change. Slight changes in climate may cause abrupt changes in ecosystems that are not easily reversible. Some of these responses, including insect outbreaks, wildfire, and forest dieback, may adversely affect people as well as ecosystems and their plants and animals. USGS scientist Colleen Charles discusses a new report on the impacts of a warming world on ecosystems.

Arctic Heats Up More than Other Places

corecast@usgs.gov (U.S. Geological Survey - CoreCast Team) — Mon, 2 Feb 2009 12:00:55 UTC

Temperature change in the Arctic is happening at a greater rate than other places in the Northern Hemisphere, and this is expected to continue in the future. As a result, glacier and ice-sheet melting, sea-ice retreat, coastal erosion and sea level rise can be expected to continue.

USGS scientist Joan Fitzpatrick discusses a new report on past climate variability and change in the Arctic.
