In 2016 two influential new publications raised the possibility of a rapid acceleration of sea level rise in the 21st century – to ±2 metres (DeConto & Pollard) or more (2-5m, Hansen et al). In this background article we take … Continue reading →
Here at Bitsofscience.org we’ve written quite extensively on why a direct shutdown of the Gulf Stream is unlikely – and that the collapse scenario featured in that one movie we only ever saw the trailer of probably did not even … Continue reading →
“The Southern Ocean is a large window by which the atmosphere connects to the interior of the ocean below” – Jean-Baptiste Sallée from British Antarctic Survey, lead author of new publication in the August edition of Nature Geoscience.
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 →
As the climate changes, so does the face of local meteorology. In the Arctic it appears the Beaufort high is gradually making place for increased dominance of low pressure systems, leading to a more dominant positive phase in the Arctic … Continue reading →
Of course you know these people that by now feel a bit cornered and say ‘okay, perhaps temperatures are going up. But that’s what it does, the global climate changes all the time.’ Well, to keep things simple: no, it … 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 →
Glacials and interglacials on the northern and southern hemisphere somehow do not seem to correspond. This has led to a ‘thermal bipolar seesaw theory,’ whereby an off-mode in the thermohaline circulation leads to an ice age in Europe, but excess … Continue reading →
