High Arctic temperatures drive sea ice to record low
2016-02-06 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Discover: The plot above shows how Arctic region air temperatures at about 3,000 feet above the surface varied from average in January 2016. The North Pole is at the center of map. The air temperature for the region at this height was about 13 degrees F above the 1981-2010 mean -- a record. At the surface, January saw an average temperature that was 11 degrees above normal, also a record.

Antarctic sea ice set for record high as Arctic heads for sixth lowest extent
2014-09-17 10:59:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: The extent of sea ice in Antarctica is set to reach a record high, scientists said on Tuesday, as they announced that Arctic sea ice appeared to have shrunk to its sixth lowest level ever. The NSIDC said that satellite data was expected to shortly confirm whether the maximum extent of sea ice at the opposite pole, in Antarctica, had set a new record. Antarctic sea ice is poised to set a record maximum this year, now at 19.7 million sq km (7.6m sq m) and continuing to increase, the centre,...
How High Will Sea Levels Go by 2100?
2013-09-24 19:15:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: Rising sea level is among the most potentially catastrophic effects of human-caused climate change. Increases in sea level strengthen the destructive power of storms, and threaten to swamp major coastal cities, as well as small-island and low-lying nations. In the United States alone, more than 8 million people live in areas at risk of coastal flooding. During the 20th century, global sea levels crept up by about 6.7 inches (17 centimeters), and the rate of increase appears to have accelerated...

Greenhouse Gas Associated With High Sea Levels Over Past 40 Million Years
2013-01-03 19:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: Researchers based at the National Oceanography Centre, Southampton, have found that greenhouse gas concentrations similar to the present almost 400 parts per million -- were systematically associated with sea levels at least 30 feet above current levels by comparing reconstructions of atmospheric CO2 concentrations and sea level over the past 40 million years. The study, published online in the Proceedings of the National Academy of Sciences (PNAS), determined that the "natural equilibrium"...
