A new study regarding the rate of sea level rise shows that the rise of ocean levels may be accelerating faster than the steady increase that was previously assumed, and may result in double the height of sea levels previously projected for the end of the century.

Previous studies made their projections based on a constant rate of sea level rise, but according to study lead Steve Nerem, professor of Aerospace Engineering Sciences at the University of Colorado Boulder, the acceleration of ice melt in Antarctica and Greenland is also accelerating the effect on the amount of water being added to the sea.

The polar vortex has divided into two sections, allowing warm air from the northern Pacific ocean to extend into the Arctic, while displacing cold Arctic air south along the west coast. While the resulting forecast means that the east coast will see milder temperatures in the coming weeks, it also calls for colder than average temperatures in the west, and yet more above-average warmth in the Arctic, already suffering from record-low sea ice levels.

A recent survey of Arctic permafrost has revealed that the northern tundra holds the world’s largest reserve of mercury, with its size estimated to be in the tens of millions of gallons. Ordinarily, the presence of the toxic metal wouldn’t be a problem, as it is locked away in the frozen soil, but researchers are concerned that as the permafrost melts due to global warming, that mercury trapped there could be released into the environment.

While the global average temperature continues to rise, it does so disproportionately around the world: the closer to the poles one gets, the more drastic this temperature rise becomes, a phenomenon in climate science called Polar Amplification. This effect has become so drastic that some areas of the Arctic, such as the Barents and Chukchi seas, are up to 4ºC (7.2ºF) warmer than average. And now these temperature extremes are breaking climate data algorithms, such as in the case of climate data being recorded in Utqiagvik, Alaska.
