Ozone hole decreasing - not a good thing ?
last update: Jan 28, 2010 01:49 PM
From a "The Hindi" article: The Antarctic ozone hole is now steadily closing. What was once regarded as one of the biggest environmental threats could now actually cause an increase of temperatures in the southern hemisphere, British scientists have claimed.
Prof Ken Carslaw, one of the researchers from the University of Leeds, and co-author of the study that said high-speed winds in the area beneath the hole have led to the formation of brighter summertime clouds, which reflect more of the sun’s powerful rays, stated “These clouds have acted like a mirror to the sun’s rays, reflecting the sun’s heat away from the surface to the extent that warming from rising carbon emissions has effectively been cancelled out in this region during the summertime. If, as seems likely, these winds die down, rising CO2 emissions could then cause the warming of the southern hemisphere to accelerate, which would have an impact on future climate predictions.”
