More accurate predictions of future climate and improved understanding of today’s warming are possible with new data from the first comprehensive reconstruction of an extreme warm period. Past warm periods provide real data on climate change and are natural laboratories for understanding the global climate system. USGS scientists Harry Dowsett and Marci Robinson discuss this research and implications.

The USGS estimates that there are 85.4 trillion cubic feet of undiscovered, technically recoverable gas from natural gas hydrates on the Alaskan North Slope. This is the first-ever resource estimate of technically recoverable natural gas hydrates in the world. This assessment shows that gas hydrates could add significantly to the U.S. energy mix. The Alaskan North Slope holds one of the nation’s largest deposits of technically recoverable natural gas. USGS Director Mark Myers and USGS scientist Timothy Collett discuss the assessment and its results.

Early this morning, October 29, 2008, a magnitude 6.4 earthquake struck near Quetta, Pakistan. Twelve hours later, a second 6.4 struck in the same area. Dr. Harley Benz, Scientist-in-Charge at the USGS National Earthquake Information Center, fills us in with the details.

What if you knew that a magnitude 7.8 earthquake would happen in less than three weeks? In this video interview, USGS earthquake scientist Dr. Lucy Jones explains that millions of Southern Californians will be preparing as if they do know, thanks to the Great Southern California ShakeOut.

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.
