Antarctic melt could raise sea levels faster

Deutsche-Welle: Cold, white, forever icy the Antarctic should be the last place to melt in a warming climate. But a new study shows the ice continent could become the major contributor to sea level rise before the end of the century. Melting ice from the frozen continent of Antarctica currently makes up less than 10 percent of the observed rise in global sea levels - the rest comes from the thermal expansion of warming seas, and from melting glaciers and the Greenland ice sheet. But a new analysis by an...
Error identified in satellite record may have overestimated Antarctic sea ice expansion

Guardian: There has been a lot of attention on ice at the southern pole of the Earth. To be clear, the Earths climate is changing and the Earth is getting warmer. This means that the oceans are warming, the atmosphere is warming, sea levels are rising, and ice is melting. In fact, the Earths ice is melting almost everywhere. In the Arctic, sea ice is in a long-term retreat, the Greenland ice sheet is melting, so is the Antarctic ice sheet as are the worlds glaciers. But, there is a perplexing anomaly. The...

Antarctic fur seals, once hunted to near extinction, now face climate threat
2014-07-25 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Christian Science Monitor: Climate change appears to be pulling the ecological rug out from under a once-stable population of Antarctic fur seals. Their numbers on a remote island in the South Atlantic are falling, even though an increasing proportion of survivors are displaying greater genetic variation a trait generally thought to boost an organism's ability to adapt to environmental stress. That's the pattern a pair of scientists has detected in a new study of the seal population, which researchers have been scrutinizing...
Climate change ravaging Antarctic fur seals

Agence France-Presse: A food shortage likely caused by climate change is shrinking a South Antarctic fur seal colony and changing the profile of its surviving members, researchers said Wednesday. South Georgia island's Antarctic fur seal pups have a lower average birth weight, and there are fewer breeding adults -- who hold out longer to reproduce than in the past, according to study results published in the journal Nature. Only the biggest animals survive to adulthood and reproduce. These are classic symptoms...
