Large and increasing methane emissions from northern lakes
2016-01-04 13:00:00| LifeSciencesWorld
[NEWS] Methane is increasing in the atmosphere, but many sources are poorly understood. Lakes at high northern latitudes are such a source. However, this may change with a new study published in Nature Geoscience. By compiling previously reported measurements made at a total of 733 northern water bodies - from small ponds formed by beavers to large lakes formed by permafrost thaw or ice-sheets - researchers are able to more accurately estimate emissions over large scales. <…

Climate Change Warming Worlds Lakes, Says Study
2016-01-02 16:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: A new study by NASA and the National Science Foundation reveals that climate change is rapidly warming lakes around the world, according to findings in Geophysical Research Letters. The study, published last month, used temperature data taken via satellites and ground measurements from 235 lakes around the world and analyzed temperature changes over 25 years. "What we wanted to do was see how lakes were changing over the entire globe and look at what variations there were in the warming rates...

Great Lakes leading U.S. in national marine sanctuary efforts
2015-12-29 22:49:34| Chemicals - Topix.net
At some point in the next few years, it's very likely that an 875 sqaure-mile section of Lake Michigan off Wisconsin will officially become the second freshwater national marine sanctuary in the country . But, if a handful of communities scattered across the Great Lakes have any say in the matter, it won't be the last.

Climate change is impacting lakes faster than oceans
2015-12-22 14:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: Climate change is rapidly warming lakes around the world, threatening freshwater supplies and ecosystems, according to a new NASA and National Science Foundation-funded study of more than half of the world's freshwater supply. Using more than 25 years of satellite temperature data and ground measurements of 235 lakes on six continents, this study -- the largest of its kind -- found lakes are warming an average of 0.61 degrees Fahrenheit (0.34 degrees Celsius) each decade. The scientists say this...

Earth's Lakes Are Warming Faster Than The Oceans And Atmosphere
2015-12-21 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: Some of the world's biggest temperature jumps are happening in lakes an ominous sign that suggests problems such as harmful algae blooms and low-oxygen zones hazardous to fish will get worse, says a newly released scientific report. An analysis of 235 lakes that together hold more than half the earth's fresh surface water found they have warmed an average of 0.61 degrees Fahrenheit or 0.34 degrees Celsius per decade, the report said. While seemingly insignificant, the increase is bigger than...
