Cleaner atmosphere means more Arctic sea-ice melt, study says

Anchorage Daily News: To protect human health and safeguard the environment, governments and utility companies around the world have worked -- successfully -- to reduced the amount of sulfur dioxide released into the atmosphere. But there's a downside to cleaning the air of sulfur dioxide and similar pollutants: Arctic sea ice is more exposed to solar heat, and more of it melts. Now, Environment Canada researchers, in a study published in Geophysical Research Letters, have put a number on the sea-ice melt that reduced...

Fossil Forests Found In Arctic Circle; Drastic Climate Shifts 380 Million Yrs Ago
2015-11-23 06:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: "It's amazing that we've uncovered one of the very first forests in the very place that is now being used to preserve the Earth's plant diversity," Dr. Chris Berry, a professor in Cardiff University's School of Earth and Ocean Science, said in a news release. "These fossil forests show us what the vegetation and landscape were like on the equator 380 million years ago, as the first trees were beginning to appear on the Earth." During the Devonian period (420-360 million years ago) there was a...

Fires rapidly claim more forests and peatland in Arctic
2015-11-20 18:53:00| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: David and Kristen Olesen, their two daughters, and 44 sled dogs lived at a homestead at the edge of the boreal forest on a sandy peninsula at a spot where the Hoarfrost River meets the Great Slave Lake near the Arctic Circle. In the wintertime, fog rises off the river and coats spruces in moisture that crystallizes to ice in a phenomenon called "hoarfrost." Their home was 25 miles from the closest settlement of Reliance. That summer afternoon, Kristen watched a rabbit tear out of the woods. A...

Climate change: Warm water is mixing up life in the Arctic
2015-11-20 18:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: The warming of arctic waters in the wake of climate change is likely to produce radical changes in the marine habitats of the High North. This is indicated by data from long-term observations in the Fram Strait, which researchers from the Alfred Wegener Institute (AWI) have now analysed. Their most important finding: even a short-term influx of warm water into the Arctic Ocean would suffice to fundamentally impact the local symbiotic communities, from the water's surface down to the deep seas. As...
Polar bear numbers to fall as Arctic ice shrinks: Study
2015-11-19 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Polar bear populations are likely to fall by more than 30 percent by around mid-century as global warming thaws Arctic sea ice, experts said on Thursday in the most detailed review of the predators to date. The report, by the IUCN (International Union for Conservation of Nature), estimated there are between 22,000 and 31,000 polar bears in the Arctic and said they will be increasingly vulnerable as their habitat shrinks. "Climate change will continue to seriously threaten polar bear survival...
