Warm November set month's heat record for planet

Australian Broadcasting Corporation: November was a hot month for planet Earth. Government scientists reported Tuesday that last month set a heat record. They say it was the warmest November on record, across Earth, since record-keeping began in 1880. The National Oceanic and Atmospheric Administration says average global temperature, for water and land surfaces combined, was 56.6 degrees (13.7 Celsius). That's 1.4 degrees (0.78 degrees Celsius) above the 20th century average. It was the 37th consecutive November with above-average...

EPA rules on interstate air pollution get warm Supreme Court reception

Washington Post: The latest effort to address the "good neighbor' provisions was due to go into effect in January 2012. But a divided panel of the U.S. Court of Appeals for the D.C. Circuit, acting on a challenge brought by 14 of the upwind states and a coalition of industry interests, rejected the plan and said the EPA had exceeded its authority. The government appealed and appeared to get a better reception from the eight justices who participated in Tuesday's oral arguments. (Justice Samuel A. Alito Jr. recused...
Warm Arctic Waters Emit Carbon, Though Region Carbon Sink Overall
2013-12-04 20:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: The Arctic Ocean has has long been known as a carbon sink, but a new study suggests that while the frigid waters do store large quantities of carbon, parts of the ocean also emit atmospheric carbon dioxide. Researchers from MIT constructed a model to simulate the effect of sea ice loss in the Arctic, finding that as the region loses its ice, it is becoming more of a carbon sink, taking on about one additional megaton of carbon each year between 1996 and 2007. But while the Arctic is taking on...

Greenland Ice Sheet Was Smallest When Ocean Was Warm
2013-11-26 21:35:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: In the last 10,000 years, the Greenland Ice Sheet shrank to its smallest size around 3,000 to 5,000 years ago, when ocean temperatures were also quite high, a new study suggests. The finding, published Nov. 22 in the journal Geology, suggests that ocean temperatures, not atmospheric temperatures, could be a critical factor in melting ice sheets in current global warming scenarios. Understanding the reaction ice sheets like the ones covering Greenland and Antarctica will have to climate change...
Carbon in atmosphere 'could warm planet for centuries'
2013-11-24 19:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Telegraph: Carbon dioxide which is already in our atmosphere could continue warming the planet for centuries even if new emissions were entirely halted, scientists claim. A new analysis of future carbon emission scenarios found that it may take significantly fewer emissions for global temperatures to reach unsafe levels than previously thought. Carbon dioxide, the most important greenhouse gas, has long-term effects because it can remain in the atmosphere for centuries after it is emitted. To understand...
