U.S. Using Less Water Than It Did 35 Years Ago
Host: David Hebert
Tagged: WaterMonitoring DrinkingWater farming hydrology population water (Back to Main Page)

The United States is using less water than during the peak years of 1975 and 1980, according to USGS water use estimates for 2005. Despite a 30 percent population increase during the past 25 years, overall water use has remained fairly stable.

So what else do we know--and not know--about water use in the U.S.? Learn from a USGS scientist and partners, and hear what they're going to talk about at a water use briefing on Capitol Hill.

Attention citizen scientists: We need your help watching the way the world changes!

For nature, timing is everything. So how does climate change affect the timing of things like flowers blooming and animals migrating, and why is this so important?

Learn more, and find out how YOU can help us by observing the world around you from USGS scientist Jake Weltzin, Director of the National Phenology Network.

Farming Carbon to Help the Atmosphere and the Land
Host: James Nickles
Tagged: carbon CO2 California ClimateChange farming subsidence water (Back to Main Page)

Long-standing farming practices in California's Sacramento-San Joaquin River Delta expose fragile peat soils to wind, rain and cultivation, emit carbon dioxide (CO2) and cause land subsidence.

To capture or contain the carbon, farmers would "grow" wetlands. In doing so, they would begin to rebuild the Delta's unique peat soils, take CO2 out of the atmosphere, ease pressure on the Delta's aging levees, and infuse the region with new economic potential.

We learn more from USGS bio-geochemist Robin Miller about how this could help California, the nation, and the world.
