This article is nonsense. It takes observational data from a survey, averages it, doesn’t control for obvious medical factors that more strongly influence the observed data than climate (e.g. illnesses), and then asserts that the correlation is causative.
It is not science. It’s just propaganda.
To what end? Either there’s a global conspiracy to destroy the planet or theres’s a global conspiracy to save the environment?
I look forward to reading your research article refuting this one. Please let us know the arxiv url when you're ready to publish.
Fairly sure "may" means something different to "is" but maybe I'm just not the target audience and am reading it wrong.
