Dust in the Wind Could Speed Greenlands Ice Melt
2014-06-08 19:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Despite it's name, Greenland is predominantly white, as snow and ice cover the majority of the country. New research indicates that Greenland's main color may be starting to fade and in fact darken, though, thanks to a widespread increase of dust across the ice sheets. That darkening could speed up surface melt, and with it, sea level rise around the globe. More than three-quarters of Greenland is covered by a massive ice sheet that's up to 2 miles thick in spots. It contained 684,000 cubic miles...
Big Waves Bust Up Sea Ice, May Be Playing Role in Melt
2014-05-28 19:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Big ocean waves whipped up by storms hundreds or even thousands of miles away from Earth's poles could play a bigger role in breaking up polar sea ice and thus contributing to its melt more than had been thought, a new study suggests. The study, detailed in the May 29 issue of the journal Nature, found that these waves penetrate further into the fields of sea ice around Antarctica than current models would suggest, breaking up the ice well away from the edge of the ice. And previous studies have...
Records melt across country as capitals experience weeks of unseasonably warm weather

News.com.au: COSY blankets and jumpers have remained in the wardrobe for much of May - and southeast Australia should prepare for a warmer-than-average winter. Records have melted across our capital cities as much of the nation enjoys an unseasonably warm month. The sun continues to shine on New South Wales, where Sydneysiders have experienced a run of 16 days above 22C, which is unheard of for May. The May mean maximum temperature is 23.3C - 3.9C above what Sydney usually experiences at this time of...

As mountain snow fails and glaciers melt, Pakistan faces water threats
2014-05-24 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Farmers in the valleys of northern Pakistan fear for the survival of their summer crops after a short winter of low snowfall altered the flow patterns of mountain streams, potentially robbing the farmers of water they rely on to irrigate their fields. Experts at the Pakistan Meteorological Department (PMD) and senior weather observers posted at stations in Pakistan's Upper Indus Basin (UIB) say last winter's snowfall in most of the valleys of the Gilgit-Balistan province was as much as 70 percent...

Glacial melt pours iron into ocean, seeding algal blooms
2014-05-23 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: A decade ago, a common hypothesis was that rivers and dust supplied the ocean with most of its iron. Since then, scientists have reported in several papers that icebergs and deep-sea hydrothermal vents also may be significant contributors. Scientists report in a new study this week that glacial melt may be funneling significant amounts of reactive iron into the ocean, where it may counter some of the negative effects of climate change by boosting algal blooms that capture carbon. The paper, published...
