Corals can survive warmer seas if humans don't meddle

New Scientist: Coral reefs might be able to take the heat of climate change -- if left well alone. A new study suggests reefs that are spared human interference can survive episodes of severe coral bleaching. When corals are stressed - by a sudden rise in the temperature of seawater or a change in its chemistry, for instance - they can no longer provide nutrients to the photosynthetic algae that live symbiotically within them. As a result the corals lose both the algae and their rich hues, which stem from the...

'A better path' toward projecting, planning for rising seas on a warmer
2013-04-03 21:29:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: More useful projections of sea level are possible despite substantial uncertainty about the future behavior of massive ice sheets, according to Princeton University researchers. In two recent papers in the journals Nature Climate Change and the Proceedings of the National Academy of Sciences (PNAS), the researchers present a probabilistic assessment of the Antarctic contribution to 21st-century sea-level change. Their methodology folds observed changes and models of different complexity into unified...
Coastal communities need plans for warmer world

Poughkeepsie Journal: On March 6, the National Climate Seminar hosted a conversation on After Sandy, Whats Next? with Brenda Ekwurzel, a climate scientist and assistant director of climate research and analysis at the Union of Concerned Scientists. Using Hurricane Sandy as a case study, Ekwurzel explained how coastal communities are becoming increasingly vulnerable to the combined effects of both sea-level rise and extreme weather events. Ekwurzel also explained the possible solutions that coastal communities can...

Warmer climate to open new Arctic shipping routes by 2050: study
2013-03-08 22:35:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: The quickest way to get goods from Asia to the U.S. East Coast in 2050 might well be straight across the Arctic, where a warming climate is expected to open new sea routes through what is now impenetrable ice, a study reported on Monday. Most shipping traffic between these two centers currently goes through the Suez or Panama canals, and that is likely to continue even as melting Arctic sea ice makes the far north more accessible. But increasingly warm temperatures also could make the Northwest...

Warmer Arctic with Less Ice Increases Storm Surge
2013-03-06 03:08:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Rising temperatures are shrinking Arctic sea ice, and in Canada's Northwest Territories, that means more and stronger storm surges, according to a new study. An analysis of lakebed sediments from one section of the outer Mackenzie Delta shows surges have become more intense and frequent over the past 150 years as the region has warmed and ice has retreated. The sharpest increase in surge activity came after 1980, in concert with the steepest declines in Arctic sea ice cover, concludes the research,...
