Winter Storms in California that Could Cause $300 Billion in Damage

Kara Capelli — Thu, 13 Jan 2011 00:00:00 EDT

Beginning on Christmas Eve, 1861, and continuing into early 1862, an extreme series of storms lasting 45 days struck California. The storms caused severe flooding, turning the Sacramento Valley into an inland sea. The storms were caused by atmospheric rivers, a hurricane-like phenomenon that occurs on the west coast. A storm comparable to that of 1861-1862 could occur again. To prepare for a storm of this magnitude and greater, a team of atmospheric scientists, U.S. Federal and State agencies and academic institutions have created a model scenario, called ARkStorm, for understanding the damage and impacts from a California winter storm. The scenario estimates that the State's flood protection system would be overwhelmed and more than $300 billion in damage would result. Kara Capelli spoke with Lucy Jones, chief scientist for the USGS Multi-Hazards Demonstration Project, about the results of this emergency-preparedness scenario.

Farming Carbon to Help the Atmosphere and the Land

jnickles - at - usgs.gov (James Nickles) — Mon, 29 Sep 2008 00:00:00 EDT

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.
