People might be surprised to see how today's frigid Greenland looked during the last two interglacial periods. Today, northwest Greenland hovers in the 30s and low 40s Fahrenheit and weathers snowstorms in summer. But average summer temperatures in the early Holocene (8,000 to 11,000 years ago) and Last Interglacial (116,000 to 130,000 years ago) climbed well into the 50s. www.sciencedaily.com/releases/2018/06/180604151150.htm
The temperatures have been higher than normal in the winter months and lower in the summer for the past few years. This might be due to increased cloud cover which is blocking incoming sunlight when the sun shines in the summer and blocking the outgoing radiation in the winter when the sun never shines.
“If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen.” -Samuel Adams

2021 daily NSIDC sea ice extent is in 11th place for 8.24.
We are 1 - 3 days behind 2009, 2010, 2013, and 2014.
It is possible, we will fall into 15th place within the next week.
Additionally, it has been anomalously cold in the western arctic for the past several weeks. There are already reports of melt ponds freezing over in the high arctic. The cold anomalies have been centered outside of 80 north. With positioning and orientation of the ice pack, could we make history and see a record early minimum this year? Looking at the daily trend line, we will almost certainly see an earlier than average minimum (daily losses continue to be below average, and average losses with respect to time, continue to decrease ahead of the average pace).
Ufa, Artic temperatures from Climate4you don't look especially cold. I am still puzzled why the sea ice extent seems to be holding up so well Hopeful of a modest recovery this year. If Astro is right we might see a further recovery next year
I noticed NSIDC stated "The Northern Sea Route appears closed off in 2021, despite being open each summer since 2008" This certainly suggests a big change this year.
