Scientists may have missed massive ocean warming
2014-10-06 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Science Mag: Earths oceans have absorbed more than 90% of the warming caused by greenhouse gases, researchers estimate, with the stored heat showing up as warmer seawater. But a new analysis suggests scientists may have underestimated the size of the heat sink in the upper ocean--which could have implications for researchers trying to understand the pace and scale of past warming. Seas pose a formidable challenge to climate scientists. On one hand, they are as big a player in the global climate system as...

The world is warming faster than we thought

New Scientist: It's worse than we thought. Scientists may have hugely underestimated the extent of global warming because temperature readings from southern hemisphere seas were inaccurate. Comparisons of direct measurements with satellite data and climate models suggest that the oceans of the southern hemisphere have been sucking up more than twice as much of the heat trapped by our excess greenhouse gases than previously calculated. This means we may have underestimated the extent to which our world has been...
Depth key to ocean warming trends

BBC: The deeper half of the ocean did not get measurably warmer in the last decade, but surface layers have been warming faster than we thought since the 1970s, two new studies suggest. Because the sea absorbs 90% of the heat caused by human activity, its warmth is a central concern in climate science. The new work suggests that shallow layers bear the brunt of ocean warming. Scientists compared temperature data, satellite measurements of sea level, and results from climate models. Both the...
Concerned scientists say climate warming killing forests in the Rockies

PBS: Rocky Mountain forests as we know them are in great peril, according to a new report from the Union of Concerned Scientists and the Rocky Mountain Climate Organization, with many having already been substantially damaged by the triple threat of beetle kill, wildfire and heat-related drought. The report presents new evidence that human-caused climate warming is driving those components of forest destruction. The National Climate Assessment published earlier this year included similar material,...

Warming of Indian Ocean may weaken monsoon: Study
2014-10-02 18:40:00| Climate Ark Climate Change & Global Warming Newsfeed
Times Of India: A recently published study says the Indian Ocean has been warming consistently for over a century and at a faster rate than any other region of tropical oceans - and this may weaken the monsoon. The study by scientists from Pune's Indian Institute of Tropical Meteorology (IITM), Sorbonne University in Paris and Pune's Fergusson College found the warming of the Indian Ocean has been a major contributor to the total global sea surface warming, which may have long-term effects on the climate such...
