Wir haben kaum die Oberfläche der direkten Luftkarbonerfassung zerkratzt, aber wir verlassen uns darauf, um den Klimawandel in Schach zu halten. Direktluftfassungssysteme verbrauchen viel Energie und produzieren toxische Nebenprodukte.

Will Direct Air Capture scale in the ways we need it to? Or is it just a dream?
Just imagine all the effort that went into putting the carbon in our atmosphere in the first place. It would take a similar effort to put it all back. It seems impossible or at least not likely.
The article says we currently remove 51 megatons per year, and that the figure is hoped to be 7 times that in a decade. Extrapolate that another 2 decades and we’d be at 17.5 gigatonnes annually, or 787 gigatonnes by 2100 at a constant rate from then (year 2055) on. It doesn’t seem unfeasible to pull it off, I think he bigger problem will be in preventing emissions from growing exponentially as well.
Edit for the math: 51 * 7^3 * 45=787185
