Shrinking ice worries Great Lakes scientists
2013-03-09 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Lansing State Journal: The crew of the U.S. Coast Guard cutter Bristol Bay has battled pretty much everything the Great Lakes can think up. Theyve battled 14-foot swells that left even experienced guardsmen heaving in the head. Theyve rescued stranded animals that floated out too far and barges stuck in shallow shores. The one thing they dont see as much of at least not anymore is ice. One of the Detroit crews primary responsibilities is icebreaking during the winter clearing Great Lakes waterways of...

Scientists Find an Abrupt Warm Jog After a Very Long Cooling
2013-03-07 20:11:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: There`s long been a general picture of the climate of the Holocene, the period of Earth history since the last ice age ended around 12,000 years ago. It goes like this: After a sharp stuttery warm-up following that big chill - to temperatures warmer than today - the climate cools, with the decline reaching bottom around 200 years ago in the period widely called the "little ice age." (A graph produced by Robert Rohde for his Global Warming Art Web site years ago nicely captures the general picture.)...
Scientists Say Earth Hotter Now Than Most of Past 11,300 Years

Bloomberg: The Earth is warmer now than during 70 to 80 percent of the time stretching back to the last Ice Age, according to researchers from Oregon State and Harvard universities who studied data from more than 73 global sites. The findings also show that temperature-change rates are accelerating, Shaun Marcott, a scientist at Oregon State in Corvallis and one of the papers authors, said yesterday in an interview. The study was published today by the journal Science. The research is the longest global...

Australia: Scientists study reef remnants to understand climate change
2013-03-06 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Canberra Times: Scientists have mapped and filmed the remnants of a coral reef off the NSW mid-north coast in an effort to better understand the effects of climate change. Using multi-beam sonar imaging and video cameras a team of scientists from the University of Wollongong, Geoscience Australia and the NSW Department of Primary Industries surveyed a reef near Lord Howe Island, about 600km east of Port Macquarie. Core samples, videos and a topographical map of the sea floor were captured during the two-week...

US scientists report big jump in heat-trapping CO2
2013-03-05 21:46:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: The amount of heat-trapping carbon dioxide in the air jumped dramatically in 2012, making it very unlikely that global warming can be limited to another 2 degrees as many global leaders have hoped, new federal figures show. Scientists say the rise in CO2 reflects the world's economy revving up and burning more fossil fuels, especially in China. Carbon dioxide levels jumped by 2.67 parts per million since 2011 to total just under 395 parts per million, says Pieter Tans, who leads the greenhouse...
