Reducing CO 2 levels in the atmosphere will take more than cutting emissions—we will also need to capture and store the excessive volumes of already-emitted carbon. In an opinion paper publishing in the journal Trends in Plant Science on September 21, a team of plant scientists argue that arid lands such as deserts could be one answer to the carbon-capture problem. The authors argue that we could transform arid ecosystems into efficient carbon-capture systems with improved soil health, enhanced photosynthetic efficiency, and larger root biomass by engineering ideal combinations of plants, soil microbes, and soil type to facilitate a naturally occurring biogeochemical process called the oxalate-carbonate pathway to create below-ground carbon sinks.
