I disagree, AGW is a scientific theory, (without merit I might add).
The microclimate effect of cities, ie. Paved Roads and building albedo changes the climate far more than a few extra CO2 particles in the air.
So as long as we don’t cover the whole world with cities we should be okay.
But most libs live in cities and they have no idea the climate outside the city just 20 minutes away is far colder in the winter. No wonder they believe in gore-bull warming.
