Very twilight zone like.
Putting out fires makes them worse, the only way to make them less intense is have more fires.
It only took 50 years to figure it out.
Oddly, I remember people saying this 50 years ago. Of course, now it's national news.

A new study by a team from San Jose State University and Stanford University has found that—even under heightened damage estimates—the additional mitigation costs of limiting global warming to 1.5 deg. C (relative to 2.0 deg. C) are higher than the additional avoided damages this century under most parameter combinations considered. An open-access paper on their work appears in the journal PLoS ONE
Specifically, the researchers found that under their central parameter values, limiting global warming to 1.5 deg. C results in a net loss of gross world product of roughly US$40 trillion relative to 2 deg. C and achieving either 1.5 deg.C or 2.0 deg. C requires a net sacrifice of gross world product, relative to a no-mitigation case, though 2100 with a 3%/year discount rate.
They found that the benefits of more stringent mitigation accumulate over time; the calculations indicate that stabilizing warming at 1.5 deg. C or 2.0 deg. C by 2100 would eventually confer net benefits of thousands of trillions of dollars in gross world product by 2300. . . .
Brown and Saunders note that efforts to mitigate global warming are often justified through calculations of the economic damages that may occur absent mitigation. Although the earliest damage estimates were speculative, more recent studies have provided empirical estimates of damages on economic growth that accumulate over time and result in larger damages than those estimated previously.
These damage estimates suggest that limiting global warming this century to 1.5 deg. C avoids tens of trillions of 2010 US dollars in damage to gross world product relative to limiting global warming to 2.0 deg. C. However, in order to estimate the net effect on gross world product, mitigation costs associated with decarbonizing the world’s energy systems must be subtracted from the benefits of avoided damages, the authors argue. . . . .
Both 1.5 C warming (world is already at 1C) and 2C warming are unlikely to be the limits to warming. 3.5C is more likely. And as the cost isn't linear, we should pay more attention to worse case.GRA wrote: ↑Sat Oct 17, 2020 12:40 amA new study by a team from San Jose State University and Stanford University has found that—even under heightened damage estimates—the additional mitigation costs of limiting global warming to 1.5 deg.

Assuming their analysis is correct, ISTM the question boils down to how much does the current generation owe to future ones, and how many generations out?
I fixed that for you.
