People love apocalyptic rhetoric about climate change - we're going to destroy the Earth, make it "uninhabitable," etc.
Keep in mind that there has been life on this planet for billions of years. During the Eocene -- just a blink of an eye ago, in geologic terms -- the Earth was 14 degrees C warmer than it is now.
Oh, and more than 99% of all species that have ever existed went extinct before humans started using fire.
I know it is easier to talk big about topics over which we have no control. But IMO, we should focus on actually making a difference.
