Sea ice optional [image credit: BBC]
Not an indicator of supposedly dire global warming this season then? Groans from climate obsessives perhaps. Nothingburgers all round.

Arctic sea ice appeared to have hit its annual maximum extent on Feb. 25 after growing through the fall and winter, says NASA (via Phys.org).
This year’s wintertime extent is the 10th-lowest in the satellite record maintained by the National Snow and Ice Data Center, one of NASA’s Distributed Active Archive Centers.
Arctic sea ice extent peaked at 5.75 million square miles (14.88 million square kilometers) and is roughly 297,300 square miles (770,000 square kilometers) below the 1981-2010 average maximum—equivalent to missing an area of ice slightly larger than Texas and Maine combined.
This maximum ties with 2015 as the third earliest on record.
Sea ice waxes and wanes with the seasons every year. In the Arctic, it reaches its maximum extent around March after growing through the colder months, and shrinks to its minimum extent in September after melting through the warmer months.
In the Southern Hemisphere, Antarctic sea ice follows an opposite cycle.

Reblogged this on Climatism and commented:
Steady as she goes. Hardly the ‘crisis’ that they belt us all around with 24/7.
43 years? Compared to a lifetime, it’s a long period, but looking at the whole context, it’s just a spit in the ocean. In other words, cherry picking … How was the ice extent 22,000 years ago? [ret]
Roger,
The sea ice experts, “so called experts” have studied sea ice since they put up satellites to watch. They still do not understand.
We have ice core records that go back thousands of years.
Ice core records show that sequestered ice on land in polar regions grows fastest when the temperatures are the warmest and it gets colder after hundreds of years now, before 20k years ago, after thousands of years. Ice core records show that sequestered ice on land in polar regions grows slowest when the temperatures are the coldest and it gets warmer after hundreds of years now, before 20k years ago, after thousands of years. That means the oceans and the climate is cooled the most and sea ice forms when the most land ice is being dumped into the warm tropical ocean currents, causing the formation of sea ice and shutting off the snowfall until the ice depletes, then it warms and the cycle repeats. Warm times with low sea ice are necessary for evaporation and snowfall and sequestering of land ice in Polar regions.

10th lowest? So up on last year I assume?
As for the “size of Texas” its less than 5% below the average. Probably within the variability of that average.
Cooling ‘slows down’ warming 🤔
Research: North Atlantic Cooling is Slowing Down Mass Loss of Icelandic Glaciers
First published: 24 January 2022
Plain Language Summary
Icelandic glaciers are currently losing mass, but with a recent slowdown in the last decade. We show that this slowdown coincides with the development of an area of regional cooling in the North Atlantic Ocean to the south of Greenland, called Blue Blob. Cooling in the Blue Blob has been mitigating atmospheric warming in Iceland since 2011, reducing glacier melt. In a future warmer climate, North Atlantic cooling is projected to persist until the mid-2050s, further slowing down mass loss of Icelandic glaciers. High mass loss resumes thereafter as the regional cooling in the Blue Blob weakens.
