national geographic is entertainment (read: misinformation, owned by disney). this article uses dramatic photography and liberally employs weasel words like "could" and "might". even "linked" isn't as strong as you might think, as that only implies correlation, not causation. it mentions no counter-factuals or alternate hypotheses, just drives boldly forward with the messaging.

as for the second, i agree that pollution and climate change are linked, but why address the boogeyman when we have the villian right in front of us? [insert tribal, mediopolitical reasons unrelated to making lives better.] pollution is clearly a problem now. climate change might be a problem in decades/centuries. and the causation is pollution -> climate change, not the other way around, so fixing pollution (not simply CO₂) is win-win, but not the other way around.

a long arc of digesting and triangulating information has led to my understanding of the problem, which doesn't easily link to a study or two. i'm a proponent of sensible environmentalism, not tribal bandwagoning. i was a member of https://netimpact.org/ in business school and took courses on sustainability (i.e., i've studied the problem using primary sources rather than relying on mass media to tell me what to think).
