Yes, but these scrubbers need vast amounts of energy. Most of which emit carbon. We simply need to curb emissions. With the possible exception of basaltic rock weathering, DAC is not practical. Large DAC projects fail to reach forecasts, even when these forecasts for plants costing tens of millions of dollars only aim to extract global emissions of two or three seconds.

Extraction of the resource is not free. But with advances in solar panels and battery technology, the economic arguments for much fossil fuel use is fast disappearing. We were never going to make difficult decisions for the sakes of our grandchildren - we're much too selfish for that - but as renewables put more money in our pockets, we might just make the right decisions. Even if it is for the wrong reasons.
