Global Warming May Boost Dead Zones in Oceans
2015-02-10 15:43:00| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: The findings raise concerns about whether warming conditions will make certain parts of the ocean uninhabitable for a wide range of marine life that needs oxygen to survive. Scientists are finding clues about how climate change could affect marine life by looking deep into the global ocean's past experiences with warming. Through analysis of ocean sediment data, researchers at the University of California, Davis, found that the last time the planet underwent a major temperature change at the...

It's Not All Bad News For Earth's Oceans
2015-02-01 23:05:00| Climate Ark Climate Change & Global Warming Newsfeed
National Public Radio: ARUN RATH, HOST: A recent report on the health of the oceans includes some welcome good news. Ocean habitats seem to be in pretty good shape, at least compared to things on land. Douglas McCauley is an ecologist at UC Santa Barbara and a lead author of the study. DOUGLAS MCCAULEY: To put things into numbers, in the past 500 years, we've seen on land 500 animal extinctions occur. In the oceans - the same time period - only 15 marine animals have been driven extinct. RATH: Now, having seen the whole...
New research reveals extreme oxygen loss oceans during past climate change
2015-01-29 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: New research published this week reveals that vast stretches of the ocean interior abruptly lost oxygen during the transition out of the last ice age that occurred 17,00010,000 years ago. This event was the most recent example of large-scale global warming, and was caused primarily by changes in Earths orbit around the sun. Past climate events provide informative case studies for understanding what is currently happening to the modern climate system. For this research, marine sediment core records...

Govts Will Forge First Treaty Protect Global Oceans
2015-01-28 11:28:00| Climate Ark Climate Change & Global Warming Newsfeed
Environment News Service: Government representatives from around the world agreed Saturday to develop the first legally-binding agreement to conserve marine life in the high seas and international seabed, an area covering roughly half the planet. After four days of intense deliberations at UN Headquarters in New York, delegates reached consensus to begin negotiating a UN treaty that addresses the protection of marine life in areas beyond national jurisdiction -- the global ocean commons. Delegates leaving the UN in...

Australia: Warm oceans make 2014 the hottest year on record, Mildura Victoria's hottest town

Age: Unusually warm seas helped drive annual global temperatures to a record level in 2014 and are likely to ensure this year has a similarly hot start, climate experts say. Two leading US agencies, the National Oceanic and Atmospheric Administration and NASA, have declared last year was the hottest, based on data going back to 1880, adding to an earlier confirmation by Japan. Globally, average land and sea-surface temperatures were 0.69 degrees above the 20th century average, "easily surpassing"...
