Average Arctic sea ice extent for May 2022 was 12.88 million square kilometers (4.97 million square miles) (Figure 1). This was 410,000 square kilometers (158,000 square miles) below the 1981 to 2010 average, yet it was the highest May extent since 2013. As was the case for April, sea ice extent was slow to decline, losing only 1.28 million square kilometers (494,000 square miles) during the month. Ice loss in May occurred primarily in the Bering Sea, the Barents Sea, and within Baffin Bay and Davis Strait. However, several openings, or polynyas, in the pack ice have started to form, particularly within the eastern Beaufort Sea, the Chukchi Sea, the Laptev Sea, and around Franz Joseph Land in the northern Barents Sea. Ice also started to pull back from the shores of Russia in the Kara Sea. In Hudson Bay, the ice started to melt out in the south within James Bay and off of Southampton Island in the north. Overall, the daily sea ice extent tracked within the interdecile range (encompassing 90 percent of the 1981 to 2010 daily values) for much of the month. By the end of the month, extent was close to the sea ice extent observed in late May 2012.

June 5 2023 The seasonal decline in Arctic sea ice extent was moderate through much of May before picking up pace over the last few days of the month. Meanwhile, Antarctic sea ice extent remained far below previous satellite-era record lows for this time of year.
Most of the Arctic Ocean in May was dominated by below average sea level pressure, as much as 10 millibars below average north of the Laptev Sea (Figure 2b). This type of pattern is known to be generally associated with below average air temperatures over the Arctic Ocean.

I look at the long term trends though and there is no doubt in my mind that the planet's ice is vanishing at a "geologically" alarming rate. This is the key to understanding what's happening in the cryosphere, the melt over the time period. We are seeing melt measured in decades that would under normal cycles take hundreds or thousands of years.

The state of Alaska where I live is basically a huge peninsula sticking out into the Arctic Ocean and the Bering Sea. Our weather is strongly influenced by the amount of sea ice covering the Bering Straights and the Arctic Ocean. In the past during the winter the Arctic Ocean and the Bering Straights would freeze up and basically Alaska would become an extension of Siberia, with no open water in between, and then it would slowly melt back a bit in the summer. But now there is much much less ice and much much much more open water around Alaska, and our climate here is changing very very quickly.
It's very interesting to watch everything change all around me here in a funny "I'm-living-in-a-climate-disaster-movie" kind of way.
Cheers!

One summer soon all that ice will be gone up where you are, Antarctica will begin shedding vast amounts of it's land based ice and peak oil constraints will be felt in every corner of the globe.

I enjoy your posts a lot. Unlike a certain dullard who posts mostly childish ad homs at this site, you've always got something interesting and new to say.
Happy day ahed hey to you too.
Or as I like to say...
HAVE A GOOD ONE.
Cheers!

In 2007 a shift in surface circulation currents and extreme melting reduced this 50 percent of very hard older ice down to about 20 percent. Of the 30 percent lost about half or about 15 percent melted in place and the rest was driven out of the basin and down the coast of Greenland on the east coast as icebergs that melted in the North Atlantic some time that summer and fall.

sea ice extent
Up here in Alaska the winter sea ice extent is just as important as the summer sea ice extent because it controls our winter weather...
Arctic sea ice extent settles at record seasonal minimum
September 19, 2012
... Summer temperatures across the Arctic were warmer than average, but cooler than in 2007. The most notable event was a very strong storm centered over the central Arctic Ocean in early August. It is likely that the primary reason for the large loss of ice this summer is that the ice cover has continued to thin and become more dominated by seasonal ice. This thinner ice was more prone to be broken up and melted by weather events, such as the strong low pressure system just mentioned. The storm sped up the loss of the thin ice that appears to have been already on the verge of melting completely.
