Current rate ocean acidification eclipses ancient extinction event

Blue and Green: The acidification of the worlds oceans, occurring today because of manmade carbon emissions, is happening 10 times faster than it did 56 million years ago, when many species were wiped out as a result. Around 9 million years after the extinction of the dinosaurs, between the Paleocene and Eocene epochs, a mysterious climate event caused global temperatures to soar and killed off many forms of marine life. Scientists are uncertain of the causes of the PaleoceneEocene Thermal Maximum (PETM),...

World On The Brink Of A Sixth Great Extinction
2014-05-31 14:58:00| Climate Ark Climate Change & Global Warming Newsfeed
Design and Trend: A new study has revealed that plant and animal species are becoming extinct at least 1,000 times faster than they did before humans entered the picture. The study claims the world is "on the brink of a sixth great extinction" The study compared past and present rates of extinction, and found a lower rate of extinction in the past than scientists had thought. Species are in fact disappearing from the planet about 10 times faster than previously believed. Stuart Pimm of Duke University, and...

Climate changes push native Montana trout toward extinction -study
2014-05-28 20:12:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Climate changes that have made Montana streams much warmer over the last 30 years are helping invasive trout push their native cousins toward extinction, researchers said on Tuesday, saying study is an example of global warming reducing biodiversity. The study led by ecologists with the U.S. Geological Survey links warming streams and reduced spring flows in the Flathead River basin in western Montana and Canada to a sharp rise in interbreeding between rainbow trout introduced by government fishery...

Climate warming driving native trout to extinction, study says
2014-05-26 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
NBC: Montana fly fishing guide and shop owner Jason Lanier hooks a feisty rainbow trout almost every day he hits the waters in the lower valley of the Flathead River system. From an angler's perspective, the catch is a thrill. Rainbows put up a good fight, much better than the one offered by the state's native westslope cutthroat trout. "And cutthroats that have some rainbow genetics in them typically fight harder for sure," the owner of the Bigfork Anglers Fly Shop told NBC News. About 20 million...

Long lives, big impacts: human life expectancy linked to extinction
2014-04-15 22:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Mongabay: Since the arrival of Homo sapiens, other species have been going extinct at an unprecedented rate. Most scientists now agree that extinction rates are between 100 and 1000 times greater than before humans existed. Working out what is driving these extinctions is fiendishly complicated, but a new study by scientists from the University of California, Davis and the Nebraska Cooperative Fish and Wildlife Research Unit suggests that human life expectancy may be partly to blame. Increased life expectancy...
