Never argue against global warming/climate change.
You are playing on their turf if you do that.
Argue that humans have not demonstrated any ability to control the climate. The planet has been going from tropical periods much warmer than now to ice ages all by itself for billions of years. Ask how will they put a stop to that, and why would that be a good thing?
And ask how upsetting the natural climate of the planet is going to turn out, assuming they can. They can’t know, which means they need to stop trying before they screw up.
I have to disagree.
I know a con when I see one,a deal on magazine subscriptions or a guy saying he can asphalt my driveway.
global warming/climate change is a con.
