MOC stands for Meridional Overturning Circulation, and although it refers to the same global pattern of ocean currents (‘conveyor belt’) as the thermohaline circulation, this story shows why actually MOC is the more accurate name, as it is not just … Continue reading
Extremely cold winters for Europe persisting for several months are very rare. The last one to fit the definition occurred in 1963, almost half a century ago. Still many weather forecasters and media seem inclined (as again happened this year) … Continue reading
The cold winter of 2011-2012 that some meteorologists have predicted for Ireland, England, Scotland, France, Belgium, the Netherlands, Germany and Denmark is in fact to be called unlikely.
Is it the albedo effect? Is it increased ice dynamics? Dutch researchers add a third player to better understand why Arctic melting is happening as fast as it is. The clue is in the winter polar night skies, they say.
The Permian-Triassic Mass Extinction was the largest in our planet’s history. Enormous disruptions of the carbon cycle led to climate change, ocean acidification and ocean anoxia – and with an estimated 90 percent of all species dying out Earth almost … Continue reading
During the Earth’s ice ages the Pacific Ocean stored large amounts of carbon, which for some reason it released again close to the last glacial period’s end, warming the world and melting most of the icecaps. That is how the … Continue reading
Researchers of Utrecht University say the Greenland ice sheet may be more stable now than during the Eemian, the previous interglacial period, which lasted from 130,000-114,000 years BP. It turns out back then Arctic insolation was bigger – although still … Continue reading
Icelandic scientists say they have discovered a new overturning site, where cold, dense, deep water is formed and transported through a separate route towards the Denmark Strait and further south into the Atlantic Ocean.
From raw measurements we know that in recent years the oceans seem to take up a smaller percentage of the CO2 we emit. Analysing available data a group of three researchers finds in part of the North Atlantic this is … Continue reading
