There's an enormous quantity of carbon tied up in frozen permafrost. It's starting to thaw. It's starting to release greenhouse gases that threatens to become an unstoppable process which would greatly amplify global warming.
Well, where did the greenhouse gases come from if we didn't have people to create them?
It's dead organic matter, dead animals and plants.
That's a threat that would exist if people never existed.
It's a threat that would exist, but the activities of people are unlocking that threat.
What do you say to people who theorize that the Earth is returning to its normal temperature? You don't think Maybe it was 30 degrees warmer when dinosaurs roamed the Earth?
If you want to characterize a temperature above today's temperature as normal, you're free to do that. But that doesn't mean that's a planet that we want to live on. If we let the Earth.
I don't want to get philosophical.
I'm not getting philosophical. I'm getting extremely practical.
You're what?
I'm being extremely practical.
Yeah.
