Carbon Capture is the rage now. Even Elon Musk put out a prize of USD 100 million for anyone who could come up with a viable and scalable technology for carbon capture.
When Elon Musk shares an idea with the world and allows the world to pursue it, rest assured, there is no money to be made there. Case in point - Hyperloop. But I digress.
I can’t even begin to tell you how stupid, looking at the climate problem as uni-variate (single variable) problem, is. Instead of a long lecture, let me put it like this -
You are cooking a dish, let us say preparing some Hollandaise sauce. Assume you were sprinkling salt and all the salt in the salt shaker fell in. Also, because of could create “shareholder value” you let the sauce boil and the allowed the salt to mix. Now, if you have to set this dish right, I suppose you will add water and proportionally increase other ingredients to set it right. In other words, you will need to do a lot of engineering to remove the salt, there is no salt capture machine that will solve the problem. The salt would have already interacted with other ingredients.
Climate change is the same, but with carbon-di-oxide in the atmosphere.
Also, the situation with climate change is that we continue to add carbon to the system. The equivalent would be having a steady drip of salt going on getting added to the sauce.
