The one time a non Mercator map would have significantly helped them tell this story.. and what do they pick?
A 3D globe view "from above" was probably simplest.

In the 60s the Soviets actually considered damming off the bering strait to make Siberia warmer. Kennedy apparently wasn't even too opposed to the idea.
However the parts where the effect is bad for humans heavily outweigh the good parts. Because that's where humans live now, there's a reason we didn't live in northern Siberia much. We live where the conditions were favourable in the past and those are largely becoming less favourable. Meaning huge amounts of people wanting to move in a hurry, the kind of thing that tends to conflict.
Just want to point this out because there seems to be a lot of pooh-poohing going around right now, saying it's not so bad. But it is already bad for the places where we actually live and it's only beginning.

China is working with Russia and other countrys to build out a vast rail network that is pushing westward, and I think delivering small(token) trains to scandenavia already. The bottom line is that China can deliver what you want, where you want it, when you want it, at a price you cant say no too.

According to that graph we're not currently at the absolute record low (2020 and 2016 were lower apparently), but only because so many of the recent years were record-low years.
