Ron Barmby is an engineer with four decades of geoscience experience who has authored two books challenging mainstream climate nonsense.

What historians will definitely wonder about in future centuries is how deeply flawed logic, obscured by shrewd and unrelenting propaganda, actually enabled a coalition of powerful special interests to convince nearly everyone in the world that CO2 from human industry was a dangerous, planet-destroying toxin. It will be remembered as the greatest mass delusion in the history of the world - that CO2, the life of plants, was considered for a time to be a deadly poison.
– Richard Lindzen, Atmospheric physicist and former MIT professor
His books Sunlight on Climate Change: A Heretic's Guide to Global Climate Hysteria and Sunset on Net Zero: A Heretic's Guide to the Futile CO2 Target argue that climate emergency declarations are politically motivated rather than scientifically based, examining the physical limitations of carbon dioxide as a greenhouse gas and describing Net Zero policies as "pointless, unachievable, and unfair".

Describing himself as a "heretic, not a denier," Ron contends that global warming has a large natural component and that future human CO2 emissions will have insignificant warming effects whilst helping to feed the global population.
When I listen to the public debates about climate change, I am impressed by the enormous gaps in our knowledge, the sparseness of our observations and the superficiality of our theories.
– Freeman Dyson, Theoretical physicist and mathematician

Ron laid this down in a kind of Q&A style. Highly recommended listening.
