Earth-Solar Cycle Spurs Greenhouse Gases, Studies Show
May 23, 2006 12:00 AM - Deborah Zabarenko, Reuters
Greenhouse gases are known to spur global warming, but scientists said Monday that global warming in turn spurs greenhouse gas emissions -- which means Earth could get hotter faster than climate modcorresponding drop in greenhouse gas emissions, the scientists reported.
Report Says Ozone Hole May Disappear by 2050
May 22, 2006 12:00 AM - Associated Press
The ozone hole over the Antarctic is likely to begin contracting in the future and may disappear by 2050 because of a reduction in the release of chlorofluorocarbons and other ozone-depleting gases, according to a team of Japanese scientists.

Climate -- Not Humans -- Killed off Mammoths, Research Suggests
May 11, 2006 12:00 AM - Reuters
Climate shifts were probably responsible for the extinction of the mammoth and other species more than 10,000 years ago, not over-hunting by humans, according to new research published on Wednesday.
Dolphins, Like Humans, Recognize Names

Scientists have found about 10-20 new species of tiny creatures in the depths of the Atlantic in a survey that will gauge whether global warming may harm life in the oceans, an international report said on Thursday.
Zanzibar Dolphin Deaths Puzzle Scientists
May 4, 2006 12:00 AM - Ali Sultan, Associated Press
Preliminary investigations have failed to yield an explanation of why hundreds of dolphins left their deep offshore habitat, got stranded in shallow waters and later washed up dead on Zanzibar's northern coast, a scientist said.
Global Warming Weakens Vast Pacific Climate System
May 4, 2006 12:00 AM - Deborah Zabarenko, Reuters
Climate scientists identified a likely new victim of global warming Wednesday: the vast looping system of air currents that fuels Pacific trade winds and climate from South America to Indonesia.
Ozone Layer Shows Signs of Recovery, Scientists Claim
May 4, 2006 12:00 AM - Patricia Reaney, Reuters
The ozone layer is showing signs of recovering, thanks to a drop in ozone-depleting chemicals, but it is unlikely to stabilise at pre-1980 levels, researchers said on Wednesday.
