Rising CO2 levels causing 'tooth decay' in sea organisms
2013-07-27 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Times of India: Rising carbon dioxide levels in the atmosphere are having a catastrophic effect on microscopic marine life, according to scientists. Experiments by the University of St Andrews show microscopic organisms, called foraminifera ('forams'), suffer the equivalent of tooth-decay as seawater becomes more acidic. Foraminifera are tiny single-celled organisms that build intricate shells to protect themselves. They feed on algal cells called diatoms, which they break open using tooth-like structures on their...

Melting Sea Ice Causing Decline in Harp Seal Populations
2013-07-23 01:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Warming temperatures in the North Atlantic Ocean have lead to a decline in sea ice, which is leaving populations of young harp seals dead in the water, according to researchers at Duke University. "Stranding rates for the region's adult seals have generally not gone up as sea ice cover has declined; it's the young-of-the-year animals who are stranding," said David Johnston, a research scientist at Duke's Nicholas School of the Environment, of the pups not even a year old. "And it's not just...
Scientists say jet stream causing weather whiplash as it wobbles
2013-07-21 17:09:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: The jet stream - the river of air high above Earth that generally dictates the weather - usually rushes rapidly from west to east in a mostly straight direction. But lately it seems to be wobbling and weaving like a drunken driver, wreaking havoc as it goes. The more the jet stream undulates north and south, the more changeable and extreme the weather. The most recent example occurred in mid-June when some towns in Alaska hit record highs. McGrath, Alaska, recorded an all-time high of 94...

What's causing oil sheens near Deepwater Horizon spill site?
2013-07-16 20:04:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: Recurrent sheens of oil in the Gulf of Mexico near the site of 2010's Deepwater Horizon oil spill have baffled researchers and led to fears that oil may once again be spewing from the seafloor well. But a study published this week in the journal Environmental Science and Technology shows that there is no new leak: The oil is coming from isolated tanks and pockets within the wreckage of the sunken rig, according to a statement from the National Science Foundation (NSF), which funded the research....

Study: Climate change causing trees to use less water
2013-07-13 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
National Public Radio: Some trees seem to be adapting to climate change by using less water, according to a study by a team of researchers from several universities, including Indiana University, that was recently published in the journal Nature. Using atmospheric devices on a 150-foot tower in the Morgan-Monroe State Forest, IU researchers measured how much water vapor and gases were being absorbed and released by the forest. That information, combined with similar data from forests around the world, has led researchers...
