"A small plane with two sick U.S. workers arrived safely in Chile late Wednesday after leaving Antarctica in a daring rescue mission from a remote South Pole research station, officials said."
Antarctica & Arctic
Here are some recent Congressional Research Service reports relevant to the environment and energy beat, thanks to the Federation of American Scientists' Government Secrecy Project.
"Extraordinary melting in Greenland's ice sheet last summer was linked to warm air delivered by the wandering jet stream, a phenomenon that scientists have increasingly tied to global warming."
"A Spanish oil company has become the latest to abandon its federal drilling leases in the Arctic’s Chukchi Sea."
"While Arctic ice is melting at a record pace, a team of NASA-led researchers say they can explain why Antarctic sea ice has been edging in the opposite direction. That paradox has puzzled scientists for years and given climate-change deniers fodder to dispute global warming."
"After plunking down more than $2.5 billion for drilling rights in U.S. Arctic waters, Royal Dutch Shell Plc, ConocoPhillips and other companies have quietly relinquished claims they once hoped would net the next big oil discovery."
"Two years ago, a pair of scientific studies documented that the glaciers of West Antarctica, which hold back over 3 meters (nearly 10 feet) of potential sea level rise, are melting and retreating from below. The cause? It appears that these glaciers, which are perched on the seafloor deep below the ocean surface, are being lapped at by flows of warm ocean currents."
"A 187,000 square-mile swath of land and sea in Alaska was restored by a federal appeals court as a “critical habitat” for polar bears, a boon for the endangered species and yet another blow to Alaska’s tumbling petroleum industry."
"Long winters in -30C temperatures they can handle, but now Norway’s indigenous people are fighting to protect ancient reindeer grazing land from development".
