Reported by: Nicole Kilmer/Newsroom Solutions Monday, Mar 3, 2008 @04:27pm CST WTVO/WQRF - Each year, long-distance winds drop up to 900 million tons of dust from deserts and other parts of the land into the oceans.
Scientists suspect this phenomenon connects to global climate - but exactly how - remains a question. Now a big piece of the puzzle has fallen into place - with a study showing that the amount of dust entering the equatorial Pacific spikes sharply during repeated ice ages - then declines when climate warms. Researchers at the Earth Institute at Columbia University say it cements the theory that atmospheric moisture - and thus dust - move in close step with temperature on a global scale. The team says that the finding could advance the idea that seeding oceans with iron-rich dust may mitigate global warming. The study appears in the February 28 edition of Science Express - the advance online edition of the leading journal Science. |
