Key to speeding up carbon sequestration discovered

From EurekAlert.org via Proceedings of the National Academy of Sciences, comes some very hopeful news for the planet:

Scientists at Caltech and USC have discovered a way to speed up the slow part of the chemical reaction that ultimately helps the earth to safely lock away, or sequester, carbon dioxide into the ocean. Simply adding a common enzyme to the mix, the researchers have found, can make that rate-limiting part of the process go 500 times faster.

A paper about the work appears online the week of July 17 ahead of publication in the Proceedings of the National Academy of Sciences.
