Warming Was Top Factor in 2005 Hurricanes, New Data Says

Following the devastation caused by Hurricane Katrina, climate scientists began a heated debate: Was last year’s superstrong hurricane season a result of global warming?

Several experts say no, pointing to a natural long-term fluctuation in sea-surface temperatures in the Atlantic Ocean called the Atlantic multidecadal oscillation(AMO).

Few scientists doubt that human-induced global warming is occurring. But some maintain that a natural cycle played a larger role in creating last year’s bumper crop of storms.

Now a new study argues that global warming is probably the larger of the two factors.

NASA Satellite Positioning Software May Aid In Tsunami Warnings

” University scientists using Global Positioning System (GPS) software developed by NASA’s Jet Propulsion Laboratory, Pasadena, Calif., have shown that GPS can determine, within minutes, whether an earthquake is big enough to generate an ocean-wide tsunami. This NASA-funded technology can be used to provide faster tsunami warnings.”
