Due to climate change in the Arctic, this polar region is expected to become "profoundly different" by 2050. [1]: 2321 The speed of change is "among the highest in the world", [1]: 2321 with the rate of warming being 3-4 times faster than the global average.
There are several reasons to expect that climate changes, from whatever cause, may be enhanced in the Arctic, relative to the mid-latitudes and tropics. First is the ice-albedo feedback, whereby an initial warming causes snow and ice to melt, exposing darker surfaces that absorb more sunlight, leading to more warming.
The clockwise circulation of the Beaufort Gyre is induced by the wind patterns associated with the permanent anticyclonic high pressure system over the western part of the Arctic. In a clockwise-rotating gyre in the Northern Hemisphere, the Coriolis force causes the ocean water to flow inward toward the gyre's center where it accumulates ...
The season's most drastic drop in temperatures has now engulfed the central and eastern states with dangerous wind chills and the arctic air could even topple some record lows. Extreme cold ...
A brutal Arctic blast is bringing record-low temperatures and life-threatening wind chills across a large swath of the United States as snow and ice spread from the South to New England and a new ...
Ice shoves can be caused by temperature fluctuations, wind action, or changing water levels [3] and can cause devastation to coastal Arctic communities. Cyclical climate change will also play a role in the formation and frequency of ice shove events; a rise in global temperatures leads to more open water to facilitate ice movement.
It was observed for the first time in the first decade of 2000s and is perhaps linked to recent climate change. [3] The Arctic dipole lets more southern winds into the Arctic Ocean resulting in more ice melting. [1] The summer 2007 event played an important role in the record low sea ice extent which was recorded in September. [2]
