German and Spanish researchers have discovered that the Greenland ice sheet may be more vulnerable to the effects of global climate change than initially thought.
These researchers assert that the Arctic is already suffering some of the effects that, according to The Intergovernmental Panel on Climate Change (IPCC), correspond with a "dangerous climate change". Currently, the rate of climatic warming exceeds the rate of natural adaptation in arctic ecosystems.
A drastic decrease in atmospheric carbon dioxide levels appears to have been the catalyst that led to the formation of the Antarctic ice sheet.
A new study of dust-like particles of soot in the air — now emerging as the second most important — but previously overlooked — factor in global warming provides fresh evidence that reducing soot emissions from diesel engines and other sources could slow melting of sea ice in the Arctic faster and more economically than any other quick fix.
Scientists said Monday that a better monitoring network for greenhouse gases is needed to warn of significant changes and to help countries keep their emission levels honest.
A new paper appearing in the Proceedings of the National Academy of Sciences (PNAS) suggests that people, governments, and institutions that shape the way people interact may be just as important for determining environmental conditions as the environmental processes themselves.
High-Resolution Video, Photos Available Upon Request New York (Vocus/PRWEB) January 20, 2011 New research shows that 2010 set new records for the melting of the Greenland Ice Sheet, expected to be a major contributor to projected sea level rises in coming decades. "This past melt season was exceptional, with melting in some areas stretching up to 50 days longer than average,â€ said Dr.
