"This much is clear: the Arctic is warming fast,..." No it isn't. Arctic sea ice extent is normal and cyclical as can be seen from the Danish meteorological institute's data here: http://ocean.dmi.dk/arctic/icecover.uk.php

That graph literally shows the average for 1981-2000 and the last 4 years, which are consistently and significantly below the average.

Yes it is: https://nsidc.org/cryosphere/arctic-meteorology/climate_chan...

"Over the past 30 years, it has warmed more than any other region on earth"

For those who haven't been watching this topic for the past few years: permafrost melt is the most probable factor for the possibility of a near-term extinction event.

I'm pretty sure it's well known that we're currently in one of the largest extinction events.

I wish I could downvote this 100 times. I wonder how future generations will explain our decision to just stand in front of an oncoming freight train.

I remember growing up as a kid watching the intro sequence to the road warrior and thinking it was entertaining but pretty unlikely that we’d screw up that badly. But now it seems pretty prophetic.

Here's a question: What if I don't care about "future generations"?

Not a problem at all. Just admit it so we can be honest about where your arguments come from.

A species that destroys its habitat will go extinct.

So I guess we’ll see if natural selection removes people like you from the gene pool so the species itself can continue to evolve or if the dynamics are too extreme and this is part of the great filter.

From another perspective, we are "one of the largest extinction events".
