While the title here isnt exactly inaccurate, I will say, for the people that read the headline and not the article, that this doesn't say what I would have expected to, with that title. I was expecting it to be about the simulated climate effects of a geoengineering effort being worse than expected, ie "the side-effects are underestimated and show up when we gamed things out", wheras the article barely even touches on what the simulated results for the climate were, and is instead meaning more "people proved unable to cooperate on this and powerful countries preferred to develop their own geoengineering programs and sabotage efforts to make them work with their rivals by lying about everything"
