Sorry, I didn't reply about the climate point.

Certainly the climate is changing: we are still coming out of an ice age. But it's not due to anthropogenic carbon dioxide.

The environment suffers from other forms of pollution, and overfishing, for example.

But I don't waste my time trying to convince people about the CO2 point. They have been subjected to too much repetition, and most haven't had sufficient education in degree-level physical chemistry to read the papers.

A better route is to make people aware of other lies, so that they begin to understand how much they are lied to, and why, and by whom. E.g. see talks by Mike Yeadon, which you will find on Rumble, Odysee, etc - the uncensored sites.
