Exactly that's what I think too. We have to do the removal much faster than we did the actual burning. And the removal will only cost us money, not fuel our economy. I just don't see this happening at significant enough scale. And the capture will have lots of environmental impact too if we do it at that massive scale.

And I agree about the carbon tax. It could even pay for some of the removal.

The strange thing here now in Europe is that greener alternatives like trains are taxed much higher than dirtier ones like airplanes. Because trains have VAT taxes on them, but the planes fly on kerosene that's exempt from tax and the price kept down due to international agreements.

As a result trains aren't a reasonable alternative and won't be for at least the next 20 years or so (as the train network would have to be scaled up significantly which would have been happening already if it was more a better alternative to flying). It's a shame because Europe is a great place for this with lots of short-distance trips.
