More and more literally devastating evidence of global warming keeps coming up from across the world. A glacier in Norway is shrinking fast and toxic Californian// seawaters are killing marine life in their thousands.
Global warming continues to wreak havoc. A couple of days ago it was reported that a Norwegian glacier had shrunk on an island 1,000 km from the North Pole, a usually frozen fjord (a long narrow arm of sea between high cliffs) is ice-free and snow bunting birds have migrated back early.
"This glacier is dying," guide Eirik Karlsen said on a visit to a tunnel through the ice left by last summer's melt water cascading through the heart of the fast-retreating 3 km long glacier above the village of Longyearbyen.
In California environmentalists reported that toxic acid emanating from a type of ocean algae had sickened and killed hundreds of birds, sea lions and dolphins.
The algae population increases or "blooms" every year as the ocean waters warm but this year's bloom seems early, extensive and "very, very thick," says David Caron, who teaches in the biological sciences department at University of Southern California.
The Norwegian tunnel, big enough to walk along with ice stalactites hanging from the roof, snakes its way 15 meters below the surface of the Longyearbyen Glacier and shows that huge volumes of water flowed down towards the valley last year.
Many residents say bone-chilling temperatures, blizzards and storms always vary drastically from year to year around the world's most northerly village, with or without global warming.
Still, U.N. climate experts says the Arctic is heating up faster than the rest of the planet because of global warming, threatening human livelihoods and species such as polar bears that depend on sea ice for hunting seals.
They say dark sea water and land, once exposed, soaks up more heat than ice and snow. Glaciers are in retreat in many pPage: 1 2 3 Related medicine news :1
