Ocean circulation implicated in past abrupt climate changes
2016-07-04 23:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: There was a period during the last ice age when temperatures in the Northern Hemisphere went on a rollercoaster ride, plummeting and then rising again every 1,500 years or so. Those abrupt climate changes wreaked havoc on ecosystems, but their cause has been something of a mystery. New evidence published this week in the leading journal Science shows for the first time that the ocean's overturning circulation slowed during every one of those temperature plunges - at times almost stopping. "People...

Wind-blown Antarctic sea ice helps drive ocean circulation
2016-06-27 10:14:00| Climate Ark Climate Change & Global Warming Newsfeed
PhysOrg: A team of scientists used a computer model to synthesize millions of ocean and ice observations collected over six years near Antarctica, and estimated, for the first time, the influence of sea ice, glacier ice, precipitation and heating on ocean overturning circulation. Overturning circulation brings deep water and nutrients up to the surface, carries surface water down, and distributes heat and helps store carbon dioxide as it flows through the world's oceans, making it an important force in the...
Scientists say Greenlands vast melt hasnt slowed down the Atlantic Oceans circulation yet

Washington Post: Last year, a bombshell scientific study suggested a scenario that has long worried scientists was coming to pass: a slowdown in the North Atlantic ocean currents that usually redistribute warm and cold waters, thanks to massive ice melts in Greenland and other Arctic changes. If this is really happening, its a big deal. The circulation, sometimes called the Atlantic meridional overturning circulation or AMOC, transports enormous amounts of warmth northward from lower latitudes. If it slows down,...

Intense deep-ocean turbulence in equatorial Pacific could help drive global circulation
2016-02-23 07:01:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Waves crashing on the equatorial seafloor generate centimeter-scale turbulence that is crucial for driving ocean circulation on a global scale, Stanford scientists say. The findings, presented this week at the annual American Geophysical Union Ocean Sciences conference and recently published online in the journal Geophysical Research Letters, could eventually be incorporated into global climate simulations to improve future climate forecasts. "Climate models don't do a great job of simulating global...
