Last month’s split in the Polar Vortex caused two distinct sections of the typically-persistent low-pressure zone to push south; one into western North America, and the other into northern Siberia. In North America, this resulted in a massive cold snap on the west coast, while the east experienced above-average temperatures.
Earth’s climate has entered the state of chaos I have been predicting since the publication of Nature’s End in 1984. The terrible fires predicted on the west coast in that book started to happen this year, and the great midwestern drought will inevitably follow, when I cannot tell. But with arctic temperatures soaring beyond all expectation, even beyond belief, it must happen. With it will come reduced grains production and, quite possibly, for the first time in American history, food shortages.
Last week, temperatures in the Arctic once again went above freezing, following a split in the Polar Vortex that allowed warm air currents to flow into the region, with some stations recording temperatures 25ºC (45ºF) above normal. This event accompanies an abrupt retreat of sea ice in the Bering Sea, having lost almost one-third of its coverage in just over a week.
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.
