The recent arctic blast has pushed ice cover on the Great Lakes to levels not seen since 2022. Lake Erie in particular has become mostly ice covered in quick order. As of January 23, ice cover has ...
Younger ice (first-year ice) is shown in darker shades, while older ice (four-year or older) is shown in white. This visual shows the Arctic sea ice change and the corresponding absorbed solar radiation change during June, July, and August from 2000 through 2014. The Arctic ice pack is the sea ice cover of the Arctic Ocean and its vicinity. The ...
An arctic blast disrupts a mild winter The winter of 2022-2023 was warmer than normal, but the region was hit with a brief arctic blast in early February that set two daily records .
The Arctic Ocean is the mass of water positioned approximately above latitude 65° N. Arctic Sea Ice refers to the area of the Arctic Ocean covered by ice. The Arctic sea ice minimum is the day in a given year when Arctic sea ice reaches its smallest extent, occurring at the end of the summer melting season, normally during September.
The Arctic sea ice covers less area in the summer than in the winter. The multi-year (i.e. perennial) sea ice covers nearly all of the central deep basins. The Arctic sea ice and its related biota are unique, and the year-round persistence of the ice has allowed the development of ice endemic species, meaning species not found anywhere else.
A tornado watch has been issued for parts of western Oklahoma and northwest Texas until 1 p.m. Saturday, with the potential for tennis ball-sized hail and winds reaching up to 70 mph, per CNN.
[54]: 1249 In September 2020, the US National Snow and Ice Data Center reported that the Arctic sea ice in 2020 had melted to an extent of 3.74 million km 2, its second-smallest extent since records began in 1979. [55] Earth lost 28 trillion tonnes of ice between 1994 and 2017, with Arctic sea ice accounting for 7.6 trillion tonnes of this loss.
Ice shoves can still occur when there are ice-free summers in the Arctic, which studies suggest can happen occasionally as soon as 2050. [15] In the case of no future reduction of carbon dioxide emission it is suggested that ice-free Arctic winters are also possible, [15] potentially leading to a reduction of Arctic ice shove occurrences in ...
