“When we think about the challenges in agriculture, carbon—and how to sequester it—is near the top.” So said Roger Johnson, the president of the National Farmers Union (NFU), in opening the grassroots organization’s 2019 annual convention in March. Storing carbon in farm soils is an important climate change solution, but building the health of those soils is also critical for ensuring clean water for communities and helping farmers be productive while coping with the consequences of a climate that is already changing. And throughout the NFU’s three-day gathering, the phrase “soil health” and talk about strategies to achieve it seemed to be on everyone’s tongue.

The US Geological Survey has published the first-ever comprehensive estimate of carbon storage on federal lands under future climate scenarios. Initially, it looks like good news: federal lands are projected to store more carbon in 2050 than they did in 2005. However, a closer look reveals that a big chunk of these gains are dependent on the world staying on a relatively low-emissions pathway. The difference in net emissions from federal lands between high- and low-emissions climate scenarios has the potential to undercut the emission reductions expected under the Clean Power Plan. And going deeper, the study may not account for processes that could release much more carbon into the atmosphere.
