Arctic cold is forecast to surge through much of the Lower 48 starting later this week into next week. Bitterly cold wind chills are possible over many areas. See our Key Messages below.
In winter, this relatively warm water, even though covered by the polar ice pack, keeps the North Pole from being the coldest place in the Northern Hemisphere, and it is also part of the reason that Antarctica is so much colder than the Arctic. In summer, the presence of the nearby water keeps coastal areas from warming as much as they might ...
On 20 June 2020, for the first time, a temperature measurement was made inside the Arctic Circle of 38 °C, more than 100 °F. This kind of weather was expected in the region only by 2100. In March, April and May the average temperature in the Arctic was 10 °C (18.0 °F) higher than normal.
The colder, stabler East Antarctica had been experiencing cooling until the 2000s. [34] [35] Around Antarctica, the Southern Ocean has absorbed more oceanic heat than any other ocean, [36] and has seen strong warming at depths below 2,000 m (6,600 ft). [37]: 1230 Around the West Antarctic, the ocean has warmed by 1 °C (1.8 °F) since 1955. [33]
Earth’s poles are undergoing simultaneous freakish extreme heat with parts of Antarctica more than 70 degrees (40 degrees Celsius) warmer than average and areas of the Arctic more than 50 ...
"The Arctic air coming through Jan. 15th can be the coldest of the winter so far," Anderson said. "This batch of Arctic air will have a vast zone for fresh snow cover to work with and a direct ...
Antarctica may have up to 17,000 species; [109] while 90% of the ocean around Antarctica is deeper than 1,000 m (3,281 ft), only 30% of the benthic-sample locations were taken at that depth. [110] On the Antarctic continental shelves, bethnic-zone biomass may increase due to oceanic warming, which is likely to be of most benefit to seaweed ...
