To return we probably need to capture well below the "safe" boundary of 350 ppm of CO2, to engage all the feedback loops that will refreeze the arctic etc.
But also, why bother? Biggest problems from climate change are due to the fast change, which causes destruction of ecosystems (including human habitat). Even if we refreeze, we won't revert these losses.
- dr_dshiv 5y agoThat's why we do solar radiation management first (e g., Marine cloud brightening), to prevent the rapid change. Then we try to fix the atmospheric carbon balance. That will take a while.
- DemocracyFTW 5y ago> solar radiation management first [...] Marine cloud brightening you mean, like, throwing a spanner into a machinery we hardly understand and see whether "it sticks"? Give me a hundred planets and start the trials!
