How Can Soil Quality Slow Global Warming?

A new study from the University of Berkeley in California has found that improving soil quality could make a substantial contribution to slowing down global warming. What’s more, the practices needed to make this scenario a reality are already widely-practiced around the world and involve little technological or financial investment to implement.

The authors of the paper found that if simple initiatives like planting cover plants, sowing legumes and optimising grazing terrain were introduced on a worldwide scale, they could reduce global warming by as much as a quarter of a degree Celsius. If the controversial additive biochar was factored in, the reductions could amount to as much as half a degree. However, none of the above will have any meaningful impact without attendant reductions in carbon emissions
