Also, it's not a problem that threatens the continued existence of human life on Earth.

I've seen zero evidence, even with the most extreme climate models, that human existance is threatened.

Saying stuff like that feeds right into the deniers.

I did exaggerate, sorry. There is some credible possibility of this happen, but our current models don't predict it. [1] I think it is fair to say that climate change could be very disruptive to civilization. Eg, it could cause famines, refugee crises, collapse of some societies, etc.
