Carbon Capture and Storage

A huge question mark that hangs over the accuracy of climate projections is related to carbon capture and storage (CCS): how much will we counter our ongoing carbon emissions by grabbing CO₂ and putting it where it does no harm, such as in porous rocks deep underground?

Not much, finds a Propublica analysis.

In a summary that is short on jargon and long on lovely handcrafted illustrations, it argues that CCS technology faces insurmountable hurdles at the kinds of scales that some projections rely on.
