The reason chimpanzees are indicative of an inherent propensity towards warfare rather than it being a learned culture trait is that chimps do not have an observed unified learned culture. Their habitat ranges from Guinea on the west coast to Uganda, and the bahavior is observed in chimp communities that have no contact with each other.
This was /exactly/ the situation that I was going to write a thought about, though I replaced stalkers with abusive ex-relationship partners for a more visible display of concern (and admittedly an appeal to more extreme possibility)
Companies need to make money to keep existing, the same way we need to breathe.
If you've ever had a tyrannical boss, you'll see sometimes the company is just their fiefdom. Feeding their ego is their prime motivation and organizing principle for the company - not generating money.
"The windows are one of the most expensive features,"
The obvious follow-up is what the 80/20 might be on these features. If going with readily available double-pane windows shaves $10,000 off the cost, it may be a decent trade-off - maybe use that money to buy some solar panels instead, aiming for net-zero?
As one noted in the article ""almost certainly an underestimate", because a number of climate-health relationships are not measurable due to lack of adequate data".
Milder winters expand the range of disease-carrying insects, increase risks of wars or famine with less water, mass migrations leading to political instability, more extreme weather events like draughts and flooding leading to failed crops and other natural catastrophes...
Meanwhile much of the WHO estimate is for people dying due to heat exposure. Easy to quantify, important to know - but nowhere near the full picture.
It depends on your risk/reward curve, and your probability estimates.
Malaria is unlikely to get much WORSE than it is now. But if you think that global warming has a chance to cause catastrophic damage, two or three orders of magnitude more than malaria is causing today, then you should estimate the probability that you can impact global warming and do the EV calculation.
I suspect they did a "conservative estimate" that pops out "almost certainly at least this many people will die due to effects we understand pretty well. Other, largely independent effects could be lurking that we don't understand."
