Scientists warn that newly discovered Greenland melting could accelerate sea-level rise

ClimateWire: A large area of the Greenland ice sheet once considered stable is actually shedding massive amounts of ice, suggesting that future sea-level rise may be worse than expected, a team of scientists warned yesterday in a new study. Regional warming has triggered newly discovered ice melting in a large portion of northeastern Greenland. The area, marked NEGIS, covers about 16 percent of the island's thick ice sheet. (Most-rapid melting is indicated in red.) Map courtesy of Ohio State University. The...

Scientists probe what killed Earths megafauna: Man or climate change?

Observer: "However, it is also the case that tribes of modern humans were moving into these creatures` territories at these times - and many of us believe it is too much of a coincidence that this happened just as these animals vanished. These creatures had endured millions of years of climate change before then, after all. However, this was the first time they had encountered humans." Modern humans emerged from Africa around 70,000 years ago, travelled across Asia and reached Australia 50,000 years ago,...

Mountain thermostats: scientists discover surprising climate stabilizer
2014-03-14 19:36:00| Climate Ark Climate Change & Global Warming Newsfeed
Mongabay: What do mountains have to do with climate change? More than you'd expect: new research shows that the weathering rates of mountains caused by vegetation growth plays a major role in controlling global temperatures. Scientists from the University of Oxford and the University of Sheffield have shown how tree roots in certain mountains "acted like a thermostat" for the global climate. In warmer climates, tree roots grow faster and deeper (aided by the decomposition of leaf litter), breaking up rock...

Scientists baffled over Fukushima radiation found in park in British Columbia
2014-03-14 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
International Business Times: Radioactive activity from Fukushima has reached Fraser River Valley in Vancouver, British Columbia in Canada. Although the scientists uncovered very low levels of cesium-134 in the soil, they remain baffled as to how it arrived in the area. "The sample provided was measured and we saw cesium-134, at a very low level and not a concern to public health," Krzysztof Starosta, an associate professor of chemistry at Simon Fraser University, said. But what baffles scientists about this latest find...
