Raver32 writes: "Global warming is destroying ponds that have supported life in the Arctic for thousands of years — bad news for the North and an ominous warning to the rest of the world, says a new report by two Canadian scientists. The small, shallow ponds on Ellesmere Island, high in Canada's Eastern Arctic, are drying up and could begin to release greenhouse gases that make the problem worse, says John Smol, a biologist at Queen's University in Kingston. "What happens in the Arctic will affect us all, and not in good ways," says Smol, co-author of the report with Marianne Douglas of the University of Alberta in Edmonton. It is being published in the Proceedings of the National Academy of Sciences. Their findings are the latest in a series of troubling studies that show how global warming is transforming the Arctic. The region is heating up further and faster than any other place on Earth, and "it's the first to show signs of change," Smol says. It's like the canaries that were kept in mines to warn of bad air: "The canary is singing — it's coughing and choking.""
