Study: Melting Ice in West Antarctica Could Raise Sea Levels by 3 Meters

2015-11-03 15:09:00| Climate Ark Climate Change & Global Warming Newsfeed

Agence France-Presse: A key area of ice in west Antarctica may already be unstable enough to cause global sea levels to rise by three metres of ocean rise, scientists said on Monday. The study follows research published last year, led by Nasa glaciologist Eric Rignot, warning that ice in the Antarctic had gone into a state of irreversible retreat, that the melting was considered unstoppable and could raise sea level by 1.2 metres. This time, researchers at Germanys Potsdam Institute for Climate Impact Research...

These Ice Cellars Fed Arctic People for Generations. Now They're Melting

2015-10-30 11:00:00| Climate Ark Climate Change & Global Warming Newsfeed

National Geographic: Building an underground ice cellar to store bowhead whale and other meat in Barrow, Alaska, is no small task. Even in the summertime, permafrost is hard as a rock a foot or so below the surface. Last year Herman Ahsoak employed a jackhammer and drill to construct a cellar for the whaling crew he has captained for more than a decade. But in the spring, melting snow penetrated the hatch, and the 14-foot deep cellar "filled all the way to the top with water," Ahsoak says. Maintaining ice cellars...

Aluminum Melting and Holding Furnace has 13,700 lb max capacity.

2015-10-27 13:31:06| Industrial Newsroom - All News for Today

Along with steel plate construction and steel member-reinforced shell, aluminum melting and holding furnace (gas fired) features roof-mounted, nozzle-mix radiant burner; pneumatic flue damper; drain tap; and UL-listed control panel. Holding capacity is 13,700 lb, and melting rate is 1,500 lb/hr. While preheat hearth with full width door is used for loading ingot, clamshell door is used for loading scrap. Dip well on each side provides molten aluminum to 2 die casting machines.

Melting of Antarctic Ice Shelves Could Double by 2050, Dramatically Increasing Sea Level Rise

2015-10-13 17:00:00| Climate Ark Climate Change & Global Warming Newsfeed

EcoWatch: If countries act fast to reduce global greenhouse gas emissions, according to new research, there is still time to curtail the most cataclysmic Antarctic ice melt. However, according to a study published Monday in the journal Nature Geoscience, if fossil fuel consumption maintains its current rate, Antarctica may experience a widespread collapse of its ice shelves, which could spur significant sea level rise. Researchers employed a combination of satellite observations of ice surface melting and...

Methane release from melting permafrost could trigger dangerous global warming

2015-10-13 12:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Guardian: While most attention has been given to carbon dioxide, it isnt the only greenhouse gas that scientists are worried about. Carbon dioxide is the most important human-emitted greenhouse gas, but methane has also increased in the atmosphere and it adds to our concerns. While methane is not currently as important as carbon dioxide, it has a hidden danger. Molecule for molecule, methane traps more heat than carbon dioxide; approximately 30 times more, depending on the time frame under consideration....
