Climate Change: Mountain Ponds Dried Up in the Heat Leaves Amphibians Starving for Water

Nature World: Between less winter snowfall, increased evaporation and the lengthened period of drought occurring in the Pacific Northwest, amphibians are stressing as they lose their mountain pond habitats. "We've seen that the lack of winter snowpack and high summer temperatures have resulted in massive breeding failures and the death of some adult frogs," Wendy Palen, co-author and associate professor at Canada's Simon Fraser University, said in a news release. "More years like 2015 do not bode well for the...

Crucial Food Chain Bacteria Altered by Climate Change
2015-09-06 15:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Climate change will have irreversible and unprecedented impacts on crucial ocean microorganisms that could trigger dramatic effects further up the food chain, according to scientists. The bacteria trichodesmium is known for surviving in nutrient-poor parts of the ocean, where it converts nitrogen gas into a material that can be used by other forms of life -- from plankton to whales -- which all require it to grow. This process of "nitrogen fixation' makes the bacteria "the fertilizing agent...

Why are climate change talks always in rough weather?

Livemint: All major world leaders agree that climate change is a massive threat. The problem is that they have not yet been able to hammer out a global deal to limit the damage. Their ability to walk the talk will once again be tested in December, when representatives of 190 countries will assemble in Paris to chalk out a plan for collective action. History is not on the side of optimism. The last time world leaders sat together to discuss climate change, in 2009 at Copenhagen, there was chaos, and the...

4 Ways Polar Bears Are Dealing With Climate Change
2015-09-04 19:12:00| Climate Ark Climate Change & Global Warming Newsfeed
National Geographic: It's a tough time to be a polar bear. The Arctic predatorswhich depend on constantly diminishing amounts of sea ice to catch marine mammals such as sealsare declining in number, and fast. There are fewer than 25,000 polar bears left in the wild, according to the nonprofit organization Polar Bears International. Near the southern Beaufort Sea (map), for instance, the population has dropped about 40 percent between 2001 to 2010, from 1,500 to 900 bears. And as their habitat shrinks, they've have...

Maya Permanently Altered Environment to Respond to Climate Change, Study Says
2015-09-04 19:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: Mayan activity more than 2,000 years ago contributed to the decline of Central America's tropical lowlands and continues to influence the land and environment today, say researchers at the University of Texas at Austin. Evidence shows that during the "Mayacene" a period from 3,000 to 1,000 years ago when humans began greatly affecting the environment the Maya's advanced urban and rural infrastructure altered tropical forest ecosystems. Clay and soil sequences indicate erosion and land-use changes,...
