Arctic sea ice disappearing fast

Above image, from the National Institute of Polar Research in Japan, shows Arctic sea ice extent at a record low for the time of year, on July 4, 2021, at 8.4 million km².

Subsequently, the NSIDC also indicated that Arctic sea ice was at record low extent for the time of year, on July 5, 2021, at 8.867 million km² (image above).
This situation is the more remarkable given that we're in a La Niña period, as illustrated by the NOAA image on the right showing a forecast issued July 5, 2021, and indicating that La Niña is expected to reach a new low by the end of 2021.
Arctic sea ice is getting very thin rapidly, threatening the latent heat tipping point to get crossed soon.
The U.S. Navy animation on the right shows Arctic sea ice thickness (in m) for the 30 days up to July 4, 2021, with eight days of forecasts included.
