The Arctic is experiencing extraordinarily hot sea surface and air temperatures which are stopping ice forming and could lead to record lows of sea ice at the north pole next year, according to scientists. Danish and US researchers monitoring satellites and Arctic weather stations are surprised and alarmed by air temperatures peaking at what they say is an unheard of 20 C higher than normal for the time of year. In addition, sea temperatures averaging nearly 4 C higher than usual in October and November. “It’s been about 20 C warmer than normal over most of the Arctic Ocean, along with cold anomalies of about the same magnitude over north-
National Snow and Ice Data Centre: At the end of November and through the first week of December 2019, daily extent was tracking third lowest in the satellite record, behind 2006 and 2016. Average ice extent for the month, however, finished second lowest in the passive microwave satellite record at 9.33 million square kilometres (3.60 million square miles). This was 670,000 square kilometres (259,000 square miles) above the 2016 record low for the month and 1.37 million square kilometres (529,000 square miles) below the 1981 to 2010 average. Regionally, extent remains well below average in the Chukchi Sea, as well as in Hudson Bay and Davis Strait. Extent is also below average in the Barents Sea, but not as pronounced as has been observed in recent years. Ice now extends to the shore along most of the Russian Arctic and along the coast of the Beaufort Sea. Extent is near average in the East Greenland Sea.
The consequences will be that more heat will be absorbed into the atmosphere and sea levels will raise due to the release of fresh water from the melting ice sheet the polar front jet stream will become more wavy and methane will increase due to the thawing of the permafrost. Winters will change and get warmer and wetter in the Northern Hemisphere.
The Arctic consists of the Arctic Ocean and parts of Canada USA Russia Greenland Norway Finland Sweden and Iceland. The area can be defined as north of the Arctic Circle the approximate southern limit of the midnight sun and the polar night. The United States government has legislatively defined the Arctic as "all United States and foreign territory north of the Arctic Circle and all United States territory north and west of the boundary formed by the Porcupine Yukon and Kuskokwim Rivers all contiguous seas including the Arctic Ocean and the Beaufort Bering and Chukchi Seas and the Aleutian chain." The Arctic contains around 10% of the world’s fresh water in the form of ice and is a giant reflector of sunlight back into space helping to keep the region and the Northern Hemisphere cool and our global climate stable.

The Arctic Resilience Report found that the effects of Arctic warming could be felt as far away as the Indian Ocean, in a stark warning that changes in the region could cause uncontrollable climate change at a global level. Temperatures in the Arctic are currently about 20 C above what would be expected for the time of year, which scientists describe as “off the charts”. Sea ice is at the lowest extent ever recorded for the time of year.“The warning signals are getting louder,” said Marcus Carson of the Stockholm Environment Institute and one of the lead authors of the report.
