Impacts on oceans need urgent attention in climate talks, researchers say

2015-11-13 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed

InsideClimate: Warming waters, rising sea levels, ocean acidification and changing water currents caused by climate change are having devastating effects on marine environments, scientists say. But despite these effects, which researchers say will intensify and spread inland as the planet warms, oceans have not been a focus of international climate negotiations. The authors of a set of five studies on oceans and climate change in a special issue of the journal Science published Thursday hope to change that. ...

Warmer oceans mean some cod stocks will never fully recover

2015-10-29 19:20:00| Climate Ark Climate Change & Global Warming Newsfeed

New Scientist: ailure to include changes in sea temperature in fisheries models has led fisheries managers to overestimate some stocks by two to five times, leading to overfishing. Now warmer water may make the recovery of one cod fishery to previous levels impossible. Cod off the north-east coast of North America has historically been one of the worlds great protein resources. But overfishing caused a crash in the biggest stocks off Newfoundland and Labrador, where cod fishing has been banned since 1992. The...

Seagrass gardens are needed to cap the carbon bomb in the oceans

2015-10-21 01:01:00| Climate Ark Climate Change & Global Warming Newsfeed

New Scientist: Stopping the underwater carbon emissions time bomb could require widespread seagrass transplantation. Seagrass is up to 35 times more efficient at sequestering carbon than rainforests, and stores it for millennia in the sediment below. But over the past century 29 per cent of global seagrass has been destroyed and as a result it has been estimated that it is releasing carbon at a rate similar to the emissions of Australia and the UK combined. Now an analysis of a seagrass disturbance shows that...

Climate change is killing the unsung heroes of the oceans: Krill

2015-10-20 23:14:00| Climate Ark Climate Change & Global Warming Newsfeed

Grist: Have you thought about krill recently? No? Weird. Well then, allow me: Krill those tiny, shrimp-like crustaceans that are among the most important marine wildlife are falling victim to climate change. And because of krills position on the food chain, this could be a very big problem. While you might not eat krill, that fish you had for lunch probably does, the New York Times reports: In the Southern Ocean, most marine life is a direct predator of krill or just one step removed. Diminishing...

Warming Oceans May Threaten Krill, a Cornerstone of the Antarctic Ecosystem

2015-10-19 12:00:00| Climate Ark Climate Change & Global Warming Newsfeed

New York Times: Every day for a week, So Kawaguchi peered intently into the jars of cold water holding harvested krill eggs. None were hatching. In his laboratory in Hobart, Tasmania, on the edge of the Southern Ocean, he could see that the carbon dioxide he had pumped into the icy seawater had killed the eggs. Stories from Our Advertisers We thought the krill might be more robust, said Dr. Kawaguchi, a biologist who works for the Australian governments Antarctic Division. We were not expecting such a clear...
