One of the potential solutions to our current carbon dioxide problem is the effective yet controversial use of carbon scrubbers. Carbon scrubbers absorb excess carbon from the atmosphere and store it or process it for recycling. Critics argue that simply taking out carbon from the atmosphere is more costly and less effective than the simple solution of stopping excess carbon dioxide release in the first place, yet scientists do see the need for such a direct way of controlling carbon outputs. In this recent article by the Christian Science Monitor, new developments in carbon scrubbers are outlined, and scientists speak out about its benefits and shortcomings.
