The largest industrial carbon capture facility we have built will mitigate ~3 seconds of global warming in a year. It won't get us anywhere without net zero emissions, even if we assume improvements of multiple orders of magnitude. Even a magic material that perfectly binds to atmospheric CO2 would require rounding up molecules in numbers I don't know the English for. This does open up the possibility of using the 1/3rd of arable land (26% of the terrestrial surface) being tied up growing feed as forests again, though. According to Current Affairs, re-foresting 70% of our terrestrial surface (not possible without drastic food production and consumption changes) would mitigate 1/10th of our global emissions. It's a lot of CO2 we're talking about, your car (if you have one) on average releases a metric ton of the stuff every 2000 miles. |
