How does it come "global warming" or "greenhouse gases" are so rarely mentioned in the articles about rising temperatures at North Pole?

It seems there is among scientists a fear of retaliation by the future Trump administration if they dare write such words. Unfortunately, climate change is not a "hoax". We can feel it in Europe with high temperatures never seen before.
