In the south the temperatures are about 45 °F (7 °C), decreasing north to 40 °F (4 °C) or less; a maximum of 60 °F (16 °C) is hardly ever reached except at the heads of fjords as in southwestern Greenland, where marine influences are less marked. 4Korea Polar Research Institute, Incheon, Republic of Korea

At +1.9°C, the mean annual surface air temperature (SAT) anomaly for October 2018-September 2019 for land weather stations north of 60° N, relative to the 1981-2010 mean, is the second highest value (after 2015/16) in the observational record starting in 1900 (Fig. The summer is everywhere a time of sudden changes. These results are consistent with a National Snow and Ice Data Center study that found record loss of sea ice around Greenland’s periphery in 2002. “Climate change is the challenge of our generation, and NASA’s vital work on this important issue affects every person on Earth,” said NASA Administrator Charles Bolden. 7Geophysical Institute, University of Alaska Fairbanks, Fairbanks, AK, USA
the American McMurdo station - Continental High Latitude Coast The record-breaking year continues a long-term warming trend — 15 of the 16 warmest years on record have now occurred since 2001. Comparing this more recent trend with long-term data, scientists are trying to determine to whether this 25-year warming trend will continue, or is part of a longer-term cycle of ups and downs.

Only in the central polar basin does the annual net radiation fall below zero. The first half of the 20th century saw climatic amelioration in the Arctic, with higher temperatures found particularly in winter and especially around the Norwegian Sea. Arctic Data Sets from the Polar Science Center at University of Washington/Applied Physics Laboratory ; Historical data from the First International Polar Year, 1881-1884 from NOAA ; Freshwater Switchyard of the Arctic Ocean - from the University of Washington Polar Science Center At this time sea ice failed to leave coastal areas in the summer in the eastern Canadian Arctic for the first time in living memory. the Drift, Thickness and Mass Balance of Arctic Sea Ice, CPC/NCEP
Seasonal air temperature variations are divided into autumn 2018 (October, November, December [OND]), and winter (January, February, March [JFM]), spring (April, May, June [AMJ]), and summer (July, August, September [JAS]) of 2019 (Fig. station consists of 6 months when it is fairly stable from April March was exceptionally warm over much of Alaska, the Yukon, and western Northwest Territory, where most places set all-time record high monthly means, in some cases 3°C warmer than any previous March. 2016; Kim et al.

UK. Red bars represent global temperature anomalies in El Niño years, with the red line showing the trend. Occasional storms originating in the Barents and Bering seas may penetrate the adjacent sectors of the polar basin and bring a temporary rise in temperature accompanied by snow or blowing snow.

Especially warm localized air temperatures during spring and summer over west Greenland supported extensive ice sheet melt events and early regional snow melt. 2018), and decreased air pollution (Acosta Navarro et al. while(x=eval(x)); In the south the climate of the inland ice cap has maritime characteristics with heavy precipitation, mainly snow from passing cyclone disturbances.
