Climate models must account for numerous factors, including overlooked natural processes like soil degradation. Soil, holding 80% of the Earth’s carbon, releases greenhouse gases under drought conditions, potentially exacerbating climate change. New research highlights the importance of incorporating soil health into climate predictions and advocates for sustainable land use to mitigate these effects.
However, some other natural processes have been overlooked. Farshid Vahedifard, professor and Louis Berger Chair in civil and environmental engineering, points to an important one that lies directly beneath our feet and covers most of our planet above water.
