Good news - prescient

Looks like President Trump is building ice breakers - ships rated for sailing through pack ice in the arctic.

The US Navy returns to an increasingly militarized Arctic
The U.S. Navy’s Barents Sea patrol is the latest sojourn into an increasingly militarized Arctic, where questions of international law are proliferating.

For the first time since the end of the Cold War, the U.S. Navy is making regular trips to the Arctic Circle, with the four-ship patrol sailing in the Barents Sea. Three of the four ships, which sailed alongside the British Royal Navy frigate Kent, were destroyers based in Rota, Spain, as part of an operation spearheaded by the U.S. Navy’s 6th Fleet.

The trip into Russia’s backyard was the latest in what the U.S. Navy has made clear will become a habit in the frigid waters of the Arctic. And that it was carried out by Europe-based destroyers could herald even more operations in the High North as the service plans to grow to six destroyers forward-deployed there from today’s four.

The patrol in the Barents Sea, much of which is part of Russia exclusive economic zone, follows high-profile patrols by the American aircraft carrier Harry S. Truman in 2018 and a surface action group patrol in 2019. And while a Naval Forces Europe news release made clear Russia was given advance notice of the patrol to avoid confusion, the message is still pointed: The U.S. Navy is back in the Arctic Circle after being gone for 30 years.

A lot of mineral and oil wealth up there and no clear "owners".

Also, maritime activities will be impacted by the climate either way - I am seeing a coming cold period of 50-300 years duration. These have happened before. Our sun is at a very low output - lowest since 1913. 1913 was when the Modern Warm Period started. The 1960's through the 1980's were a time of major solar activity and are the times when our climate warmed the most. Now, things are cooling off again. Either way and for whatever reason, we need to maintain an enhanced presense up there and it looks like our President is laying the groundwork for just that.
