Arctic Ocean overheating

By |2022-12-05T10:37:38+00:00December 5th, 2022|

Arctic sea ice extent was 10.31 million km² on December 4, 2022. At this time of year, extent was smaller only in two years, i.e. in 2016 and 2020, both strong El Niño years. With the next El Niño, Arctic sea ice extent looks set to reach record lows. 

The NOAA image on the right indicates that, while we’re still in the depths of a persistent La Niña, the next El Niño looks set to strike soon.

The image below shows high sea surface temperature anomalies near the Bering Strait on December 2, 2022, with a “hot blob” in the North Pacific Ocean where sea surface temperature anomalies are reaching as high as 7°C or 12.6°F from 1981-2011. The Jet Stream is stretched out vertically from pole to pole, enabling hot air to enter the Arctic from the Pacific Ocean and from the Atlantic Ocean.

The image below shows a forecast for December 5, 2022, of 2m temperature anomalies versus 1979-2000, with anomalies over the Arctic Ocean near the top end of the scale.

The situation is dire and the right thing to do now is to help avoid or delay the worst from happening, through action as described in the Climate Plan.
