This is like using a soda straw to address a flash flood.

Will Knapp, cofounder of the CCS startup Cocoon, believes it is much easier to capture CO2 directly from places it is emitted, such as factories or steel plants, than from the general atmosphere.

That should be a no brainer, but the main problem is how efficient these efforts are. How much money does it take to "sponge" one ton of CO2? and how much energy is necessary to do it and store it permanently? The amount of space is not the bottleneck here, but the amount of resources that are necessary.

Exactly! Well said!

I have more faith in plants and algae/cyanobacteria taking care of the CO2.

Too much of anything can be a problem!

REMEMBER: Plants still need CO2 to live which affects other things. Life exisst on Earth because the environmental recipe was mwah magnifique.

We also need it to block out bad things from outer space.

Carbon dioxide in the atmosphere is at historically low levels. It would be extremely beneficial for the planet and for human beings to at least double the CO2 content in the atmosphere.

That's not the only joke around. A few days earlier I've read about a renowned 'expert', whose thesis and proposal is, that the problem is very easily and effortless solved, when everyone on this planet plants about 40 new trees which then in sum absorb all the bad atmospheric CO2. He of course didn't explain where the needed area for all the many trees comes from , especially in big cities, but anyway, he is a celebrated expert.

Your claim is false and no authority in the field supports it.

Any reference? lot of people have completely misrepresented things said by experts (for example pretending an example said precisely to prove it is not feasible was the proposed solution.

I read that as sarcasm.
