Antarctic sea ice reaches new record maximum
2014-10-09 01:14:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Sea ice surrounding Antarctica reached a new record high extent this year, covering more of the southern oceans than it has since scientists began a long-term satellite record to map sea ice extent in the late 1970s. The upward trend in the Antarctic, however, is only about a third of the magnitude of the rapid loss of sea ice in the Arctic Ocean. The new Antarctic sea ice record reflects the diversity and complexity of Earth's environments, said NASA researchers. Claire Parkinson, a senior scientist...
Arctic ice shrinks as Antarctic ice expands

Australian Broadcasting Corporation: CHRIS UHLMANN: As Australians prepare for a long hot summer it's fair to say that not many of us are pondering the extent of sea ice in the Arctic. But scientists say we should be. The extent of the ice melt is both an important barometer and a cause of climate change. The latest satellite data shows the big melt has set in and that means big consequences for everything from walruses to the gases trapped by the permafrost. At the same time, ice closer to home in the Antarctic is growing but...

Antarctic Sea Ice Officially Hits New Record Maximum
2014-10-07 20:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: It's official: Antarctic sea ice hit its annual winter maximum on Sept. 22, reaching a record area of 7.76 million square miles, the National Snow and Ice Data Center (NSIDC) announced Tuesday. Antarctic sea ice extent for Sept. 22, 2014 was 7.76 million square miles. The orange line in the figure shows the 1981-2010 average extent for that day, and the black cross indicates the geographic South Pole. That maximum extent was 595,000 square miles above the 1981-2010 average extent, the NSIDC...
Gravity Shift Reveals West Antarctic Ice Loss
2014-09-26 22:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: The West Antarctic Ice Sheet is headed toward unstoppable collapse according to recent studies. A new visual released by the European Space Agency show what the start of that collapse looks like both for the mass of the ice sheet and its signature on the planets gravitational field. We think of gravity as a constant, holding us in place on the planet. But the reality is there are small changes in gravity all over the globe. Not enough that youll feel lighter on your feet in one place compared...
Antarctic Sea Ice Hits a Record Max, and Thats Not Good
2014-09-18 20:18:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Desk: For the third year in a row, the sea ice ringing Antarctica has set a new record. Its extent is the farthest now since observations began in the late `70s, and scientists say the growth is largely the result of climate change. Antarctic sea ice melts during the early part of the year but typically packs it back on by September. The ice broke last year`s record for extent on Monday, according to a report in New Scientist. It`s the latest evidence of a small but significant growth trend of about...
