We've known about climate change for more than a century, but we're pigs, we don't care.

I think it’s important not to use the “we” word here.

1) Many people know and care. 2) some people lie for profit 3) other people are willfully ignorant and allow the liars keep at it because it’s more convenient.

And even among those who know and care there’s different amounts people are willing to do about it. I imagine you (who theoretically know and care) still drive, fly, use plastic, Eat foods grown with petroleum based fertilizers, buy products shipped long distances with petroleum. (As do I)

The key is to go after the liars so we can set sane policies based on findings of fact pursued in good faith.
