It's worth watching a new Netflix show called "The Polar Sea".
There's a bunch of save the world drivel in it, but, there are amazing contrasts as well. The best may be the last 3 episodes, but all worth seeing. The NOAA monitoring station and reports directly address the impact of man's involvement, so they say.
My favorite of many is the Inuit lady who likes that things are warmer, and that plants are now growing up there. She was forced to live up there to cement Canada's claim to those lands in the 50's. Canada built military bases up there (now gone), much like China is building islands in the South China Sea.
