Eiffel Tower-Sized Channels Discovered Beneath Antarctic Ice Shelf
2013-10-07 13:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: The discovery of hundreds of kilometers worth of channels beneath a floating ice shelf in Antarctica could help experts understand how the ice will respond to changes in environmental conditions, according to a study published Sunday in the journal Nature Geoscience. Researchers from the University of Exeter, Newcastle University, the University of Bristol, the University of Edinburgh, the British Antarctic Survey and the University of York located the channels using satellite images and airborne...

Vast streams found beneath Antarctic ice sheet

Telegraph: The streams of water, some of which are 250m in height and stretch for hundreds of kilometres, could be destabilising parts of the Antarctic ice shelf immediately around them and speeding up melting, researchers said. However, they added that it remains unclear how the localised effects of the channels will impact on the future of the floating ice sheet as a whole. The British researchers used satellite images and radar data to measure variations in the height of the Filchner-Ronne Ice Shelf...
Risks grow for Antarctic life

Age: Turns out it's the little things we need to worry about in climate change. When they are in trouble a great polar ecosystem might also be having problems. The oceans are absorbing so much carbon dioxide that they are acidifying at an unprecedented rate, the International Program on the State of the Oceans said. Geological records show the current acidification is unparalleled in at least the last 300 million years, IPSO's latest report said. ''We are entering an unknown territory of marine...

Polar opposites: Why climate change affects Arctic & Antarctic differently
2013-10-02 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: The sea ice around Antarctica reached a record high in August of 7.2 million square miles (18.6 million square kilometers) -- the greatest extent observed since recordkeeping began in 1979. But as Antarctic sea ice grows, the sea ice of the Arctic is shrinking dramatically. The Northern ice cap reached a record low of 1.32 million square miles (3.42 million square km) in September 2012, due to warming air and waters. If the Earth is warming, and both ends of the planet are affected by climate...
