When an El Nino hits, the lives of penguins are in peril.  During the 1997 El Nino the penguin population fell by a third. During Climate Change a difference in temperature of at least one degree can be a life and death situation for penguins.  Researchers followed a group of about 15 breeding penguins from 1992 to 2010 on the […]

Antarctic ice sheet is more vulnerable to carbon dioxide than expected

Results from a new climate reconstruction of how Antarctica’s ice sheets responded during the last period when atmospheric carbon dioxide (CO2) reached levels like those expected to occur in about 30 years, plus sediment core findings reported in a companion paper, suggest that the ice sheets are more vulnerable to rising atmospheric CO2 than previously thought. Details appear in two […]

Life abounds under Antarctic ice

Despite no exposure to sunlight or fresh air for more than a million years, a lake located half a mile beneath the Antarctic ice sheet sustains an entire ecosystem, scientists have confirmed—raising the prospect that life might exist in similar environments elsewhere in the universe. Researchers had long suspected the existence of tiny life-forms living below the ice pack, and […]
