Data are provided as temperature anomalies against the seasonal average over a past basis period, as well as in absolute temperature values. The baseline period for the published temperature anomalies was changed in January 2021 from 1981-2010 to 1991-2020. [4] All the data products can be downloaded from the UAH server. [5]
Climate models predict that the temperature increase in the Arctic over the next century will continue to be about twice the global average temperature increase. By the end of the 21st century, the annual average temperature in the Arctic is predicted to increase by 2.8 to 7.8 °C (5.0 to 14.0 °F), with more warming in winter (4.3 to 11.4 °C ...
A reconstruction of Arctic temperatures over four centuries by Overpeck et al. 1997 reached similar conclusions, but both these studies came up against the limitations of the climate reconstructions at that time which only resolved temperature fluctuations on a decadal basis rather than showing individual years, and produced a single time ...
[15] [16] Since 2013, Arctic annual mean surface air temperature (SAT) has been at least 1 °C (1.8 °F) warmer than the 1981-2010 mean. In 2016, there were extreme anomalies from January to February with the temperature in the Arctic being estimated to be between 4–5.8 °C (7.2–10.4 °F) more than it was between 1981 and 2010. [17]
The new record should be a wake-up call for the rest of the world, scientists say, because it means the planet is growing warmer.
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 Arctic ice pack undergoes a regular seasonal cycle in which ice melts in spring and summer, reaches a minimum ...
A United Nations agency confirmed today that an arctic temperature record of more than 100.4 degrees Fahrenheit was reached in a Siberian town last year.
The cities of Banak, Norway, and Utsjoki, Finland, are shown on a map depicting warm conditions on July 7, 2021. Exceptional warmth has seeped well into the Arctic Circle in the northernmost parts ...
