Enabled by climate change right? Wonder which ports and countries will benefit from lesser ice in future.

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.
