If it takes > 100 years and all the energy of tens of billions of tonnes of fossil fuel to put us in a state of extreme peril then yes, it will at least * take another 100+ years and all the energy of tens of billions of tonnes of fossil fuel to reverse out of that position.

* Thanks to the arrow of time, the issue of unbreaking a glass, methane release and other factors it very realistically could take more time and energy to get out of the hole we seem intent upon driving into.
> Technology is for solving problems.
It's not 'magic' though and I have little time for green washing or praying to the technology fairy.
