Well, call any anthropogenic CO2 amount in the atmosphere "battery" then...
Next Tuesday? Sometime this summer? Next year? A decade from now? 2070?
Everybody knows there are problems with producing too much CO2. However, nearly everyone’s hoping (but not saying) that the bill doesn’t come fully due until they’re dead. And by “fully due” I mean “directly effects their day-to-day life in a truly drastic way.”
There's a reasonable case that this gained force _last_ summer, i.e. in 2020

But yeah, it takes a few decades for the bill to come fully due from a "decline in birth rate".
Stop the supply of money, it goes away.
