By Richard Heinberg 10 January 2012 From competition among hunter-gatherers for wild game to imperialist wars over precious minerals, resource wars have been fought throughout history; today, however, the competition appears set to enter a new—and perhaps unprecedented—phase. As natural resources deplete, and as the Earth’s climate becomes less stable, the world’s nations will likely […]
By David Archer7 January 2012 Let’s suppose that the Arctic started to degas methane 100 times faster than it is today. I just made that number up trying to come up with a blow-the-doors-off surprise, something like the ozone hole. We ran the numbers to get an idea of how the climate impact of an […]
Visit msnbc.com for breaking news, world news, and news about the economy December 30 (MSNBC) – Jim Maceda travels to Siberia to interview Sergei Zimov, who has published a series of scientific papers exposing the importance of permafrost and high-latitude carbon dioxide and methane emissions in the global carbon cycle. Zimov initiated the Pleistocene Park […]
By Bill Rigby27 December 2011 SEATTLE – Scientists in Alaska are investigating whether local seals are being sickened by radiation from Japan’s crippled Fukushima nuclear plant. Scores of ring seals have washed up on Alaska’s Arctic coastline since July, suffering or killed by a mysterious disease marked by bleeding lesions on the hind flippers, irritated […]
By JUSTIN GILLIS20 December 2011 In my article over the weekend about the climate risks from buried Arctic carbon, I omitted any discussion of one issue that sometimes appears in the news: methane deposits under relatively shallow seawater near the coasts of Siberia, Canada and Alaska. It was a purposeful omission because my piece focused […]
By Alan Buis, Alan.buis@jpl.nasa.gov, 818-354-0474, Jet Propulsion Laboratory, Pasadena, CADecember 14, 2011 PASADENA, California – By 2100, global climate change will modify plant communities covering almost half of Earth’s land surface and will drive the conversion of nearly 40 percent of land-based ecosystems from one major ecological community type – such as forest, grassland or […]
By JUSTIN GILLIS16 December 2011 FAIRBANKS, Alaska – A bubble rose through a hole in the surface of a frozen lake. It popped, followed by another, and another, as if a pot were somehow boiling in the icy depths. Every bursting bubble sent up a puff of methane, a powerful greenhouse gas generated beneath the […]
By Nataliya Vasilyeva, AP Business Writer 17 December 2011 USINSK, Russia – On the bright yellow tundra outside this oil town near the Arctic Circle, a pitch-black pool of crude stretches toward the horizon. The source: a decommissioned well whose rusty screws ooze with oil, viscous like jam. This is the face of Russia’s oil […]
Contact: Sofia Holmgren, Department of Earth and Ecosystem Sciences, Lund UniversityTel. +46 709 289778, Sofia.Holmgren@geol.lu.se 16 December 2011 Nitrogen from human activity has been polluting lakes in the northern hemisphere since the late 19th century. The clear signs of industrialisation can be found even in very remote lakes, thousands of kilometres from the nearest city. […]
Preparing for the winter storms, a bulldozer piles up a protective bank on the north shore. The coastline has become increasingly vulnerable to erosion as the sea ice retreats. More open water allows waves to build up in the fierce Arctic winds. Point Hope lies south of lease site 193 where oil giant Shell plan […]
