If prices are getting very high, Satoshi would not really need hundreds of billions of Dollars, it makes more sense if he is voluntarialy organizing a serious "giveaway" and distributed it to non-profitable organizations working agains climate-change, to red-cross, fund educational programs, etc...
He would remain very, very rich, would make Bitcoin safer and definitely write his name in history.
Satoshi is not stupid enough to believe in the climate change garbage. A religious nut could not have made something like bitcoin.
I don't want to be carried off-topic and I also don't know how things are in the US much (where seemingly most of the religious nuts and climate-deniers are), but I would associate religious nuts with denying climate change, not the other way round as your statement suggests. Why do you think that religious nuts in particular are those supporting scientifically evidenced climate change? (When they opposed scientifically evidenced evolutionary theory, for instance.)
Too bad, we are officially derailed.
The so-called manmade global warming shit is pure politics and superstition. The science is, in fact, divided on how much and even if we make a meaningful difference, what the factors are and useful responses to it.
But even if we pretend we are in fact warming the planet, that is vastly preferable to keeping the pre-oil and coal status quo because that would result in another ice age. We are at the tail end of one of the short warm periods, so keep on burning that coal and oil. If they are right there is a nonzero chance we are warding off an ice age, and if they are wrong any attempts to "fix" things would just be money out the window.
Additionally, just for completeness sake, keep in mind there are no actual "climate scientists". There is no such thing, it doesn't exist. There are geologists and meteorologists and such, but there are no actual climate scientists. It's a term the media made up.
