Some Antarctic glaciers reached tipping point in 2009
2015-05-22 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Australian Broadcasting Corporation: THE FIRST SIGNS Antarctic glaciers have reached some kind of melting 'tipping point' have been noticed by scientists from Europe. The group of eight scientists, led by Dr Bert Wouters from the University of Bristol used sophisticated satellite measurements of the Antarctic glaciers that empty into the Bellinghausen Sea, on the Southern Antarctic Peninsula which reaches up almost to South America. Glaciers are in effect, frozen rivers of snowpack, moving incrementally towards the ocean. These...

Antarctic Peninsula experiences dramatic ice melt
2015-05-22 10:50:00| Climate Ark Climate Change & Global Warming Newsfeed
Blue and Green: An equivalent of the UKs annual domestic water supply is being lost in ice melting in the Antarctic Peninsula according to new satellite research led by the University of Bristol. The Antarctic Peninsula is experiencing dramatic losses in ice mass according to new research published on Friday. Studies of satellite data led by researchers at Bristol revealed that around 60 cubic kilometres of ice is melting every year, equating to the annual domestic water supply to the UK. Published in the...

Antarctic in 'dramatic' ice loss
2015-05-22 00:44:00| Climate Ark Climate Change & Global Warming Newsfeed
BBC: Satellites have seen a sudden dramatic change in the behaviour of glaciers on the Antarctica Peninsula, according to a Bristol University-led study. The ice streams were broadly stable up until 2009, since when they have been losing on the order of 56 billion tonnes of ice a year to the ocean. Warm waters from the deep sea may be driving the changes, the UK-based team says. The details of the satellite research are published in Science Magazine. They include more than 10 years of space...

Glaciers in Antarctic thought stable suddenly melting massive rate
2015-05-21 19:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Independent: A sudden and massive melting of glaciers in a part of the Antarctic that was thought to be relatively stable has been detected by satellites monitoring the polar ice sheet, scientists have said. Many glaciers in the Southern Antarctic Peninsula have become unstable since 2009, releasing vast amounts of ice into the sea equivalent to about 56bn tonnes of meltwater each year, the researchers said. Multiple glaciers along a stretch of coastline 750km long have suddenly and consistently started...

Major Antarctic Ice Shelf May Disappear by 2020
2015-05-19 17:04:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: With climate change heating things up, and the Earth's poles rapidly melting, it should come as no surprise that a major Antarctic ice shelf may completely disappear by 2020, according to a new NASA study. The last remaining section of the Larsen B Ice Shelf, which partially collapsed in 2002, is quickly weakening, flowing faster, and becoming more and more fragmented as well as developing large cracks. This, plus the fact that two of its tributary glaciers are also flowing faster and thinning...
