Researchers identify possible glitch in Antarctic ice measurements
2014-07-23 17:39:00| Climate Ark Climate Change & Global Warming Newsfeed
Ars Technica: With all the attention given to every nuance of climate data, areas of research that would have never attracted much public interest sometimes find themselves in the spotlight. So it is with the process of measuring sea ice cover. People pay careful attention because it appears to be a leading indicator of climate change. In the Arctic, where the warming has been most intense, sea ice is retreating rapidly, with record lows having been set every few years over the past decades. But at the other...

Warm water likely to accelerate Antarctic ice melt and sea-level rise, Australian scientists find
2014-07-08 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Australian Broadcasting Corporation: Warm water is likely to increasingly displace cold water around the Antarctic coastline, prompting accelerated ice melt and more sea level rise, according to new Australian research. Scientists from the University of New South Wales (UNSW) have modelled how shifting wind patterns can drag warm water currents right up to the base of the giant ice shelves. "What you usually have is cold water sitting next to the ice shelves at about minus 2 degrees Celsius and then warm water further out," said...
Antarctic winds could accelerate sea level rise
2014-07-08 13:47:00| Climate Ark Climate Change & Global Warming Newsfeed
Blue and Green: Expected changes in Antarctic wind patterns may speed up global sea level rise, threatening coastal cities and low-lying countries around the world, a new study has warned. Climate scientists have already resigned to the fact that sea levels, driven by melting ice sheets and glaciers around the world, will rise. It will mean that entire countries will eventually be lost to the sea. However, now it is feared that coastal winds, which are thought to be strengthening because of a hole in the ozone...
Study shows penguins are adapting changing Antarctic environment
2014-06-22 07:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Blue and Green: Emperor penguins have shown to be not as attached to their nesting locations as previously thought, meaning that they could adapt much easier to their changing environment, which is being affected by rising global temperatures. A new study by the University of Minnesota has observed penguins` movements over the nesting period and found a new colony on the Antarctic Peninsula, which is believed to have relocated. Lead author of the study Michelle LaRue explained, Our research showing that colonies...

Unique & fragile Antarctic ecosystem threatened surge in tourism
2014-06-19 15:13:00| Climate Ark Climate Change & Global Warming Newsfeed
Blue and Green: Antarctica must be better protected from tourism and other human activities, after experts noted a surge in the number of visitors travelling to the planet`s last true wildernesses. In a new study, published in the journal PLoS Biology, researchers say that the existing protected-area system currently employed in the Antarctic is insufficient, now that 40,000 people visit each year. In 1990, only around 5,000 people frequented the continent. Most concern for the worlds coldest, most southernmost...
