Runaway climate change? It's more likely than we thought
2013-07-30 17:20:00| Climate Ark Climate Change & Global Warming Newsfeed
Mother Nature Network: Theres been much talk in recent years of climate feedback loops and runaway climate change, whereby the warming of our climate through man-made greenhouse gas emissions triggers further warming in the form of natural responses such as the release of methane and carbon dioxide by melting permafrost or the huge emissions caused by out-of-control wildfires. Respected NASA scientist and vocal advocate for climate action James Hansen has even claimed a runaway climate change scenario could destroy...
Global-warming Armageddon? It may be more likely than you thought
2013-07-29 16:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Independent: A runaway greenhouse Armageddon in which the oceans boil dry could theoretically happen on Earth, researchers claim. The good news is that human activity on its own will probably not be enough to trigger such an end-of-the-world scenario in the near future. Previously it was thought more energy from the sun would be needed for global warming on Earth truly to spin out of control. But new calculations from Canadian and US scientists show that catastrophic warming can occur more easily than had...

East Antarctica's ice sheet not as stable as thought
2013-07-22 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceNOW: Earth continues to hit temperature and greenhouse gas milestonesjust a couple of months ago, multiple stations measured carbon dioxide concentrations in the atmosphere of 400 parts per million, the highest in several million years. Many studies have tried to estimate how much and how rapidly the two great ice sheets covering Greenland and Antarctica might meltand the one reassuring point has been the apparent relative stability of the eastern (and, by far, larger) half of the Antarctic Ice Sheet....
Oceanic Iron content more variable than thought
2013-07-22 14:31:00| Climate Ark Climate Change & Global Warming Newsfeed
EurekAlert: The supply of dissolved iron to oceans around continental shelves has been found to be more variable by region than previously believed with implications for future climate prediction. Iron is key to the removal of carbon dioxide from the Earth's atmosphere as it promotes the growth of microscopic marine plants (phytoplankton), which mop up the greenhouse gas and lock it away in the ocean. A new study, led by researchers based at the National Oceanography Centre Southampton, has found that...
