Vast methane plumes have been discovered boiling up from the seafloor of the Arctic ocean on the continental slope of the Laptev Sea by a dream team of international scientists. Over the last decade a warming tongue of Atlantic ocean water has been flowing along the Siberian Arctic ocean's continental slope destabilizing methane ice, hypothesize the team of Swedish, Russian and American scientists.

The Arctic ecosystem, already under pressure from record ice melts, faces another potential threat in the form of rapid acidification of the ocean, according to an international study published on Monday.

Acidification, blamed on the transformation of rising levels of the greenhouse gas carbon dioxide from the air into carbonic acid in the sea, makes it harder for shellfish and crabs to grow their shells, and might also impair fish reproduction, it said.

UNITED NATIONS, Jan 17 2014 (IPS) - The widespread sectarian violence and ongoing military conflicts in several political hotspots, including Syria, Iraq and Lebanon, have not only claimed thousands of human lives and devastated fragile economies but also undermined the U.N.’s longstanding plans to eradicate hunger and extreme poverty worldwide.

WASHINGTON, Aug 6 (Reuters) - Last year was one of the 10 hottest on record, with sea levels at record highs, Arctic ice at historic lows and extreme weather in various corners of the globe signaling a "new normal," scientists said Tuesday in the 2012 State of the Climate report.

Meant to be a guide for policymakers, the report did not attribute the changes in climate to any one factor, but made note of continued increases in heat-trapping greenhouse gases including carbon dioxide, methane and nitrous oxide.
