Can Soil Microbes Slow Climate Change?

“With global carbon emissions hitting an all-time high in 2018, the world is on a trajectory that climate experts believe will lead to catastrophic warming by 2100 or before. Some of those experts say that to combat the threat, it is now imperative for society to use carbon farming techniques that extract carbon dioxide from the air and store it in soils. Because so much exposed soil across the planet is used for farming, the critical question is whether scientists can find ways to store more carbon while also increasing agricultural yields.”


“Johnson asserts that if his approach were used across agriculture internationally, the entire world’s carbon output from 2016 could be stored on just 22 percent of the globe’s arable land. He says that would provide net benefits of $500 to $600 per acre rather than net costs, if credits are provided for carbon capture and related benefits are counted, such as reduced irrigation and increased soil fertility.” Read more . . .
