Biochar and Sustainable Agriculture
Researchers at UC Berkeley found that low-tech, well-established agricultural practices such as planting cover crops, optimizing grazing, and sowing legumes on rangelands could reduce global temperatures 0.26 degrees Celsius – nearly half a degree Fahrenheit – by 2100 if instituted globally. Study senior author Whendee Silver, a professor at UC Berkeley, comments, "We found that there are a wide range of practices deployable on a large scale that could have a detectable worldwide impact. A big take-home message is that we know how to do this, it is achievable." The study also showed that by using biochar as well, these practices could offset warming potentially as much as 0.46 degrees Celsius. The caveat, Silver said, is that this "is only achievable if you couple sequestration with aggressive emissions reduction."
