Global warming pause 'may last for another decade' scientists suggest
2014-08-22 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Telegraph: The "pause' in global warming may last another decade before surface temperatures start rising again, according to scientists who say heat is being stored in the depths of the Atlantic and Southern Oceans. Global average surface temperatures rose rapidly from the 1970s but have been relatively stable since the late 1990s, in a trend that has been seized upon by climate sceptics who question the science of man-made warming. Climate change scientists have proposed more than a dozen theories to...

Scientists Propose Using Lasers to Fight Global Warming From Space
2014-08-22 06:24:00| Climate Ark Climate Change & Global Warming Newsfeed
Motherboard: At the world's first major geoengineering conference, two separate scientists put forward proposals to use lasers to modify the Earth's climate and fight global warming, from space. One suggested that a satellite equipped with a high-powered laser could grow clouds in the atmosphere below; the other proposed lasers that would blast greenhouse gases from orbit to effectively erase the agents of climate change. The highly theoretical proposals are still in their early stages, and easily count...

Global warming 'hiatus': Scientists duel over which ocean steals some heat
2014-08-21 20:27:00| Climate Ark Climate Change & Global Warming Newsfeed
Christian Science Monitor: The deeper researchers dig into the dramatic slowdown in global warming during the past 15 years, the more their findings point to natural climate variability as the cause rather than any purported end to human-triggered climate change. The latest example of this conclusion comes from a pair of scientists from the United States and China trying to identify where the expected heat has been hiding. They attribute the slowdown in warming, as others do, to heat taken up by the world's oceans,...

Don't be fooled by pause in global warming caused by 30 year cycle in ocean currents warn scientists
2014-08-21 19:56:00| Climate Ark Climate Change & Global Warming Newsfeed
Daily Kos: An apparent slowdown in global warming caused by a 30 year ocean cycle could lull people into a misperception that global warming has paused when it has not, reports Math McGrath of the BBC. During his phase of the cycle heat is being pulled deep into the Atlantic Ocean. This phase could last another 10 years which, if this theory is true will be followed by another 30 year period where stored up heat is disgorged back into the atmosphere adding together with the longer term global warming causing...
