The physical relationship between CO2 molecules and the atmosphere and the trapping of heat is as well-established as gravity, for God's sakes. It's not some mystery.

Believe in the power of your own voice. The more noise you make, the more accountability you demand from your leaders, the more our world will change for the better.
