Melting ice sheets changing the way the Earth wobbles on its axis, says Nasa
2016-04-09 02:35:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Global warming is changing the way the Earth wobbles on its polar axis, a new Nasa study has found. Melting ice sheets, especially in Greenland, are changing the distribution of weight on Earth. And that has caused both the North Pole and the wobble, which is called polar motion, to change course, according to a study published on Friday in the journal Science Advances. Scientists and navigators have been accurately measuring the true pole and polar motion since 1899, and for almost the entire...
Melting of Arctic Sea Ice Already Setting Records in 2016
2016-04-08 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: The decline of Arctic sea ice is already setting records in 2016, with the winter peak in March clocking in as the lowest since satellite records began, scientists say. A new and fuller summary of this years Arctic winter by the U.S. National Snow and Ice Data Centre (NSIDC) confirms the preliminary announcement last week that sea ice reached its annual maximum extent on March 24 this year. Covering an area of 14.52m square kilometers, this years peak winter extent is a shade smaller than...
Summer melt-driven streams on Greenland's ice sheet brought into focus
2016-04-07 01:05:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Erosion by summertime melt-driven streams on Greenland's ice sheet shapes landscapes similarly to, but much faster than, rivers do on land, says a University of Oregon geologist. The approach used to study the ice sheet should help to broaden scientific understanding of melt rates and improve projections about glacial response to climate change, says Leif Karlstrom, a professor in the UO Department of Geological Sciences. The study, online ahead of print in the journal Geophysical Research Letters,...

Shrinking Arctic ice is impacting Greenland melting
2016-04-02 01:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: Vanishing Arctic sea ice. Dogged weather systems over Greenland. Far-flung surface ice melting on the massive island. 'Blocking-high' pressure systems spawn most of the warming that melts Greenland surface ice Rutgers study says. These dramatic trends and global sea-level rise are linked, according to a study coauthored by Jennifer Francis, a research professor in Rutgers University's Department of Marine and Coastal Sciences. During Greenland summers, melting Arctic sea ice favors stronger...

Ice wall at Fukushima plant switched on, but will it work?
2016-03-31 15:43:27| Energy - Topix.net
In this March 10, 2014 file photo, workers wearing protective gears install a trial model of the underground frozen wall at the Fukushima Dai-ichi nuclear power plant in Okuma, Fukushima prefecture, northeastern Japan in their attempt to stop the leakage of radioactive water that has accumulated at the crippled nuclear power plant. Japanese regulators on Wednesday, March 30, 2016, approved the use of a giant refrigeration system to create an unprecedented underground frozen barrier around buildings at the Fukushima nuclear plant in an attempt to contain leaking radioactive water.
