Yes. Remember though that some people are invested in destroying the ability of humans to live on this planet.

Christians come to mind.

Their religion teaches them that they have both a right, and in some sects, a duty to end the world so that their messiah will return and take them to heaven.

The old oil and coal men know that they'll be dead when it all happens and have been told that stopping now won't save the world at all, so they're going right ahead with business as usual.

Then you have the stupid people that won't admit that anything is wrong, no matter what happens.

No amount of superstorms, largest ever droughts, years of hottest weather ever in recorded history will change their minds. They only lose by trying to change now, so they won't, just hoping that their belief is correct, even when the facts don't support it.

On the "good" side, they're largely correct.

Human life as we know it is already doomed. Inside fifty years the worlds oceans won't be able to support half the life they do today. Land animals are dying off faster than we can count, especially insects and we do not really understand how that's going to effect other species.

Oh, the world won't die, but that doesn't mean we'll exist as we are now at all.

And nothing we can do at this point will stop it from happening.

Yay.

You wanted doom? There you go folks. You got it.
