Climate change, not humans, killed off megafauna

Sydney Morning Herald: It's a contentious question. Why did the giant kangaroos and rhino-sized wombats that once roamed Australia die out? Scientists agree there are two contenders: climate change and humans. But they are fiercely divided over which caused the continent's megafauna to go extinct. Now, fresh results of a study at a renowned Victorian fossil site in the Macedon Ranges town of Lancefield 73 kilometres north of Melbourne has provided an answer. The diprotodon was a rhino-sized wombat that weighed...

Bobcats moving north, climate change study finds
2016-07-02 04:44:00| Climate Ark Climate Change & Global Warming Newsfeed
Prince George Citizen: Climate change could contribute to bobcat populations shifting north and one B.C. student is turning to citizen science to help prove his hypothesis. Before T.J. Gooliaff started his research in September, he believed the bobcat's northern limit was Williams Lake but conversations with foresters, trappers and residents have reported sightings in Quesnel, Prince George and Houston. "I jumped out of my chair when those photos were sent to me," said Gooliaff, a 24-year-old biology masters student...

'Perfect Storm' of Humans and Climate Change Doomed Ice Age Giants

LiveScience: The saber-toothed cat, large ground sloth and other ice age giants of South America didn't go extinct solely because of climate change or prehistoric human activity, but because of a perfect storm of the two that hit the giant beasts at the same time, a new study finds. For years, researchers have debated what felled many of the megafauna animals that weigh more than 100 lbs. (45 kilograms) shortly after the end of the last ice age. Some scientists blamed humans, who had newly colonized the...
Climate Change and Flooding in West Virginia

National Public Radio: Catastrophic floods ravaged southern West Virginia on June 23rd, 2016. As people look to the future, many are debating the role of climate change. Lots of people who grew up and live in southern West Virginia insist flooding has never been as bad as it is today. Not everyone agrees why. It's likely a combination of forces at work, but how much of a role is climate change playing? The Debate Michael Mann is a distinguished professor of atmospheric science at Penn State University and director...

Climate Change Threatening Penguins In Antarctica: Study
2016-07-01 07:17:00| Climate Ark Climate Change & Global Warming Newsfeed
NDTV: Continued warming of Antarctica due to climate change may lead to decline of 60 per cent of Adelie penguin colonies by the end of this century, a new study has warned. Climate change in Antarctica, cooling in some places and warming in others, is causing a dramatic shift in the population of Adelie penguins, researchers said. Historic satellite observations and future climate model projections were used to estimate past and future changes in habitat suitability during the penguins' chick-rearing...
