During the 46-year period when weather records were kept on Shemya Island, in the southern Bering Sea, the average temperature of the coldest month (February) was −0.6 °C (30.9 °F) and that of the warmest month (August) was 9.7 °C (49.5 °F); temperatures never dropped below −17 °C (1 °F) or rose above 18 °C (64 °F); Western Regional ...
Some parts of the Arctic are covered by ice (sea ice, glacial ice, or snow) year-round, especially at the most poleward parts; and nearly all parts of the Arctic experience long periods with some form of ice or snow on the surface. Average January temperatures range from about −40 to 0 °C (−40 to 32 °F), and winter temperatures can drop ...
In the Arctic, the sea ice extent was close to its 30-year average from 1991-2020 until July, when it began to fall below average. Its annual minimum low extent in September was the fifth lowest ...
The current multi-century period is the warmest in the past 100,000 years. [3] The temperature in the years 2011-2020 was 1.09 °C higher than in 1859–1890. The temperature on land rose by 1.59 °C while over the ocean it rose by 0.88 °C. [3] In 2020 the temperature was 1.2 °C above the pre-industrial era. [4]
The agency also said Arctic sea ice reached its fourth lowest monthly extent for October, at 19% below average. Sea ice extent is a measure of the surface area of the ocean which is covered by ice.
Last year was the hottest ever recorded, according to data from the National Oceanic and Atmospheric Administration (NOAA) released Friday. In 2024, Earth overall saw its highest global ...
The warmest years in the instrumental temperature record have occurred in the last decade (i.e. 2012-2021). The World Meteorological Organization reported in 2021 that 2016 and 2020 were the two warmest years in the period since 1850. [51] Each individual year from 2015 onwards has been warmer than any prior year going back to at least 1850. [51]
Svalbard is located in between two ocean currents – the warm Atlantic West Spitsbergen Current and the cold Arctic East Spitsbergen Current. [3] These currents have a large impact on the climate of Svalbard and in the distribution of sea ice. The warm Atlantic current on the west coast leads to an average sea temperature of 5–7 °C. [4]
