New Report Examines Complex Threats Facing Our Oceans
2013-11-04 18:35:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: A new study, Valuing the Ocean from Stockholm Environment Institute, takes an in depth look at the various challenges that threaten the health and stability of our oceans health. The study has divided the threat to the oceans into six categories: acidification, warming, hypoxia, sea level rise, pollution, and the overuse of marine resources. Acidification is direct consequence of increased carbon dioxide (CO2) emissions, as the ocean has absorbed 25-30 percent of these emissions over the last...

Oceans heating up faster now than in the past 10,000 years, says new study
2013-11-01 11:58:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: If the latest research is correct, our oceans are heating up much faster now than they have in the past 10,000 years. This is one of the conclusions that is drawn from a recently published paper in Science. The researchers (Yair Rosenthal, Braddock Linsley, and Delia Oppo) cleverly traveled back in time to explore how ocean temperatures have changed. Comparison of those temperatures to today's helped them quantify the impact that human greenhouse gas emissions are having on the planet. The story...
Oceans Warming Faster Than They Have Over Past 10,000 Years
2013-11-01 04:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Times: A new study finds that the oceans could be holding the missing heat from global warming. The experts at the U.N.`s Intergovernmental Panel on Climate Change (IPCC) had a particularly pressing challenge as they prepared the newest assessment on global warming science, the first chapter of which was released in September. The problem was that the climate wasn`t acting the way they`d expected. In recent years, global greenhouse gas emissions had kept rising--hitting an all-time record in 2012. Yet...

Acidification of oceans threatens change entire marine ecosystem
2013-10-26 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Vancouer Sun: Ocean acidification due to excessive release of carbon dioxide into the atmosphere is threatening to produce large-scale changes to the marine ecosystem affecting all levels of the food chain, a University of B.C. marine biologist warned Friday. Chris Harley, associate professor in the department of zoology, warned that ocean acidification also carries serious financial implications by making it more difficult for species such as oysters, clams, and sea urchins to build shells and skeletons from...

Warming oceans will affect the planet's poorest
2013-10-23 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: Greenhouse gas emissions from industry and power generation have begun to trigger ocean changes that will impose huge costs to the poorest people on the planet. Only in the polar regions would there be any increase in productivity or in oxygen levels. Nowhere would there be any cooling. These changes are likely to cascade through marine ecosystems and habitats to the deep ocean itself, and to affect humans along the way, according to a report published this month in the journal Public Library of...
