Biochar is similar to the burnt remains of a campfire and is an emerging climate solution because it can help soil store more carbon and retain water.Casper Hedberg/Bloomberg Philanthropies Biochar is a soil additive that can help store carbon dioxide for centuries. Cities in Minnesota and Nebraska plan to build biochar plants similar to those in Nordic countries. Climate scientists estimate 10 million metric tons of carbon removal is needed annually by 2050. A decade ago, Jim Doten was on a tour in Afghanistan with the Army National Guard searching for ways to help farmers improve soils depleted of nutrients and carbon.The geohydrologist came across some studies on biochar, a material not unlike the burnt remains of a campfire.Doten's biochar program in Afghanistan was short-lived, but the idea stuck.
