Climate change drove woolly mammoths to extinction, say scientists

LiveScience: The mighty megafauna of the last ice age, including the wooly mammoths, short-faced bears and cave lions, largely went extinct because of rapid climate-warming events, a new study finds. During the unstable climate of the Late Pleistocene, about 60,000 to 12,000 years ago, abrupt climate spikes, called interstadials, increased temperatures between 7 and 29 degrees Fahrenheit (4 and 16 degrees Celsius) in a matter of decades. Large animals likely found it difficult to survive in these hot conditions,...

Tropical fish in WA Kimberley facing extinction from climate change, researchers say
2015-07-12 00:24:00| Climate Ark Climate Change & Global Warming Newsfeed
Australian Broadcasting Corporation: Entire species of tropical fish could be wiped out by climate change, according to a research team that has spent months carrying out a study in Western Australia's north. The team from the University of Melbourne is looking at how sensitive freshwater species are to small increases in water temperatures. PhD student Matthew Le Feuvre said the results were cause for concern. "We're finding a lot of species are living potentially very close to their maximum thermal limit, so these species...

Study: world in period of mass extinction
2015-06-22 18:25:00| Climate Ark Climate Change & Global Warming Newsfeed
Blue and Green: The world is currently in a period of mass extinction, according to a new study. Human activities have been linked to the falling populations of many species but the research also warns that extinction on a large scale could threaten human existence. The study, which has been published in Science Advances, calls for fast actions to protect threatened species, populations and habitat. It estimates that species are disappearing up to about 100 fasters than the normal rate between mass extinctions,...
Earth stands on brink of its sixth mass extinction and fault is ours

Guardian: Life on Earth is in trouble. That much we know. But how bad have things become and how fast are events moving? How soon, indeed, before the Earths biological treasures are trashed, in what will be the sixth great mass extinction event? This is what Gerardo Caballos of the National Autonomous University of Mexico and his colleagues have assessed, in a paper that came out on Friday. These are extraordinarily difficult questions. There are many millions of species, many elusive and rare, and inhabiting...
Sixth mass extinction is here: Humanity's existence threatened
2015-06-19 23:03:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: There is no longer any doubt: We are entering a mass extinction that threatens humanity's existence. That is the bad news at the center of a new study by a group of scientists including Paul Ehrlich, the Bing Professor of Population Studies in biology and a senior fellow at the Stanford Woods Institute for the Environment. Ehrlich and his co-authors call for fast action to conserve threatened species, populations and habitat, but warn that the window of opportunity is rapidly closing. "[The study]...
