Well, to be fair, fossil fuels is like the cheat code to the game. We had been burning stuff since time immemorial, made sense to burn this new oil and gas stuff we dug out of the ground as it burned really well, and why stop burning coal?

If anything, we are extraordinarily lucky we got solar and wind to work as well as we have in time. Reports coming out now are starting to indicate we have a good chance at limiting ourselves to 2c warming. If it all works out, I think our future descendants might view fossil fuels as the necessary evil that brought us into the green age... or so one can hope...
