I don't see how these claims are supported by the research in question?
The main reason is that the article is paywalled (disappointed to see the authors chose to publish in a non-open access journal in 2024) but judging purely by the abstract it seems like this is just a study showing an association between being a black woman in Georgia and signs of stress-induced health issues? Also, they didn't seem to have a control group?
The negative effects of chronic stress are well-known but in the linked article this is spun into a weird narrative about microaggressions with seemingly no evidence for it? I am surprised to see the first author of the scientific article deviate so much from the published findings in her journalistic article.
Interesting article but it bizarrely completely misses what is likely to be by far the biggest source of climate change-related death: famine. Humans can shelter from the heat and we can displace our air pollution (thanks EVs) but our crops are still stuck in the field and you can pretty accurately predict yield losses from increased temperatures and increased/decreased rainfall.
This is bad enough in developed nations, where food prices will increase, choice will decrease, and general inequality will worsen. But things will become way worse in developing nations. These mostly practice inefficient, environmentally-damaging subsistence farming and when they start to produce even LESS food, they will just become failed states and hotbeds of civil war. This will bring about much more death and migration, most of it only visible to your average westerner on their TV screen as talk points for your local left/right-wing politicians.
