@lednaBM It's quoting a March 1912 Popular Mechanics article titled "Remarkable Weather of 1911: The Effect of Combustion of Coal on the Climate: What Scientists Predict" by Francis Molena, at https://archive.org/details/sim_popular-mechanics_popular-mechanics_1912-03_17_3/page/340/mode/2up?q=%22uniting+with+oxygen%2C+it+adds%22

The article ends with "generations to come shall enjoy milder breezes and live under sunnier skies."

The image from the NZ press you show "is likely a composite of two images: the newspaper's masthead patched above the paragraph about coal consumption." https://leadstories.com/hoax-alert/2021/08/fact-check-1912-newspaper-did-publish-on-effect-burning-coal.html
