New Study: Record Deep Ocean Turbulence Discovered - Impact On Climate
August 14, 2007 12:25 PM - By Libby Fairhurst, FSU
Scientists have discovered deep sea turbulence packing an energy wallop equal to about five million watt. That's comparable to output from a small nuclear reactor, according to a landmark study led by Florida State University researcher Louis St. Laurent. The discovery is described in the August 9 edition of the journal Nature.

No Development, No Peace
August 11, 2007 02:09 PM - , Global Policy Innovations Program
When a war erupts, as in Darfur, most policymakers look for a political explanation and a political solution. This is understandable, but it misses a basic point. By understanding the role of geography, climate, and population growth in the conflict, we can find more realistic solutions than if we stick with politics alone.
What A 250-Million-Year-Old Extinction Event Tells Us About Earth Today
