> Kobuk Valley National Park has warmed by 2.4 degrees Celsius (4.32 degrees Fahrenheit) since 2006 and could get another 10.2 degrees C hotter by 2100, a greater increase than projected for any other national park.

Holy shit. 10°C is currently the difference between NY and DC, or Ohio and the Gulf of Mexico, or Montana and Southern California...

What nobody ever talks about is that some of the old organic stuff (roots, leaves) in the thawing permafrost did not grow there in recent times because that stuff won't grow in permafrost . This means the thawing of the permafrost is not new and that the area used to have more stuff growing there than it does now. We should expect a greening of parts of Alaska if the warming continues and growth resumes.

Wonder if anything might still be alive in there?

>" The only constant in the Universe is change... " Seems obvious now, doesn't it.

I don’t get it.

Why do you think people should be talking about that more? I would think people aren't talking about it much because, well, it's kind of obvious.

Earlier quoted context omitted.

I don’t get it.

In almost all Spiritual/Religious teachings - they say "The only constant in the universe is change" - so Its kind of banal to say "Scientists who studied the rivers simply allot it to Climate Change" as if its the profundity of Science here...
