Meanwhile, some economic interest are quite happy with the situation
A ship has made a winter crossing of the Arctic without an icebreaker for the first time as global warming causes the region’s ice sheets to melt.

All that sloshy thin ice is now melting rapidly
In another shocking development, Alaska's Bering Sea lost a full one-third of its ice in only eight days.

Arctic melt

"It used to be just the summer when the ice was breaking low records, but we're starting to see winter really get into the act now," said Mark Serreze, the director of the National Snow and Ice Data Center.
"Both the atmosphere and the ocean are really conspiring to keep sea ice levels down," he said.
Another Record-Low Year?

As Arctic sea ice limps along toward its maximum extent, which it usually hits in mid-March, it appears to be on course for the fourth consecutive year of record lows.
"There's actually now open water in the southernmost Chukchi Sea, just north of the Bering Strait," Thoman said. The only other time on record that the Chukchi Sea has had open water this time of year was in 1989, he said.

On the Atlantic side, sea ice is also low in the Barents and Greenland seas. And in January, a tanker ship carrying liquefied natural gas from Russia became the first commercial ship to cross the Arctic's northern sea route in winter.

With sea ice levels also low in the Antarctic, the National Snow and Ice Data Center reported this month that global sea ice extent was at a record low.

"As a scientist, it's really shocking to see some of this and try to wrap your mind around what's happening and the pace that it's happening," Thoman said.

Navy to Release Arctic Strategy This Summer, Will Include Blue Water - Ice Free - Arctic Operations

Image

CAPITOL HILL — The Navy will release a new Arctic strategy this summer to reflect the potential for “blue-water Arctic” operations, service leadership said today.

Navy Secretary Richard V. Spencer told the Senate Armed Services Committee that a Navy Arctic Strategy was set for release this summer, as a follow-up to the 2014 U.S. Navy Arctic Roadmap.

Spencer noted that Russia is paving 12,000-foot runways and building up a military presence in the Arctic in the name of “search and rescue,” he said while making air-quotes. The U.S. Navy, meanwhile, does not have ice-hardened ships and has minimal presence in the region, aside from the annual ICEX submarine event.

Spencer and Chief of Naval Operations Adm. John Richardson spoke to reporters after the hearing about the Arctic strategy document. Asked what triggered the decision to revise the 2014 document now, Richardson said:
...“the Arctic triggered it” ... “the damn thing melted.”

“The Arctic ice caps are as small as they’ve been in my lifetime,” Richardson said. “And that gives rise to strategic changes. Waterways that are open. The secretary mentioned the blue-water Arctic. Continental shelves that are exposed, and the resources on those shelves. So there are strategic issues that arise from that shrinking of the icecap. And then there’s this National Defense Strategy that’s changed our focus as well. So it’s really, from a number of perspectives, about time to do that again.”

Image

OBTW, the 2014 Roadmap expected a Blue-Water Arctic after 2030 ...
Near-term: Present to 2020.
Reduction of Arctic Ocean sea ice is expected to continue, and major waterways will become increasingly open. By 2020, the Bering Strait is expected to see open water conditions up to 160 days per year, with 35-45 days of shoulder season. The Northern Sea Route (see Fig. 5) will experience up to 30 days of open water conditions, with up to 45 days of shoulder season conditions. Analysis suggests that the reliable navigability of other routes, including the Transpolar Route and the Northwest Passage, is limited in this timeframe. There will be shoulder season route variability based upon ice age, melt, and movement.

Bering Strait is already open - 2018

Image

Mid-term: 2020 to 2030.
This period will see increasing levels of ice melt and increasingly open Arctic Ocean waters. By 2025, the Bering Strait will see up to 175 days of open water (and 50-60 days of shoulder season). These figures increase to 190 days of open water (and up to 70 days of shoulder season) by 2030. For the Northern Sea Route, predictions are for up to 45 days of open water (with 50-60 days of shoulder season) by 2025, increasing to 50-60 days of open water by 2030 (with up to 35 days of shoulder season conditions). This period will begin to see greater accessibility of the Transpolar Route, which is forecast to be open for up to 45 days annually, with 60-70 days of shoulder season. Analysis suggests the reliable navigability of the Northwest Passage will continue to remain limited in this timeframe.

Far-term: Beyond 2030.
In the far-term, environmental conditions are expected to support even greater and more reliable maritime presence in the region. Major waterways are predicted to be consistently open, with a significant increase in traffic over the summer months. The Northern Sea Route and Transpolar Route should be navigable 130 days per year, with open water passage up to 75 days per year. The Northwest Passage will be increasingly open during the late summer and early fall.

Dear vtsnowedin,

the satellite image vox mundi pasted of the Bering Strait does not show much in the way of sea ice.

any comments on the discrepancy? Not sure how you can argue with a photo.

The picture Vox posted is of the very small throat of the Bering strait. Zoom out just a bit and you can see that unless you are in an aircraft carrier sized ice breaker your not going anywhere North of there for weeks or months. Saying a strait is open implies that ships can pass through it and continue on. That is not yet the case. Vox is not lying, but he is not telling the whole truth either.

Daily evolution of the record low Bering sea ice since March - now nearly all within the Bering Strait. This retreat is weeks earlier than the climatological average - crazy!

First a Geography Lesson.

I simply said the Bering Strait is Open, not the Chukchi Sea

Here's Yesterdays View of the Bering Strait - Apr 23, 2018

Image

Its 51 miles wide... See ... It's Open

Where there's slush ice, it's less than a foot thick. No Icebreaker needed.

https://www7320.nrlssc.navy.mil/GLBhyco ... nim30d.gif

The strait hasn't been this open in historic times. Normally opens end of May, beginning of June.

ImageImage

You made the strawman argument that this somehow implies something that I didn't say. You also used the NSIDC extent map which qualifies it's outline ...
... Daily extent images show ice extent at concentrations greater than 15% for a given day with an outline of the typical extent for that day. 84% Open Water is considered 100 % Ice Covered

NSIDC Sea Ice Concentration Map gives a better assessment

Hi vtsnowedin,

I don't really get your point. What does getting to Utqiaġvik (formerly Barrow) have to do with the amount of current sea ice in the Bering Sea / Strait? I think the people who follow this thread will be reasonably aware that there is still a significant amount of sea ice in the Beaufort Sea.

But at least we can agree that vox_mundi is not a liar, despite your claim that he appears to be obscuring the truth somehow.
