Earlier quoted context omitted.
You realize that would cause countless death _today_ if you don’t replace the oil with something else? People will starve, become homeless, and maybe anarchy will reign. Not just in the developed world but globally.
What do you think will happen if the temperatures keep rising, the oceans keep rising, and currently livable areas of land that hold billions of people become inhabitable?
People have been screaming "everyone will die!!!" via religious based prophecies for... all of human history. The Cult Of Climate Change is no different: a little bit of truth and a lot of faith in Revelations and the unavoidable apocalypse.
Prophecies like "all the icecaps will be gone by 2020" and "billions will die from starvation" (hint: those forecasts failed)

This is no different than the people who follow the pastor that's wrong about the date of Jesus' second coming. every year he looks at the numbers and says "next year, on x date". That date comes. and goes. and the faithful see the failed prophecy and he goes "oh look... I was wrong... it's really next year on y date". The faithful see this each year and their faith grows stronger as each failed prophecy means the next one MUST be true.
What do we think will happen? More failed prophecies. The Church of Climate Doom faithful becomes more convinced that theirs is the One True Faith as each prediction continues to prove them right.
