It was an impressive projection and, as far as I can tell, an accurate one. Organic farming’s use of cover crops and composted manure is a remarkably effective way to sequester carbon dioxide.

As recently as a month ago, Peter Melchett, Policy Director of the U.K.’s Soil Association, championed the assertion that organic agriculture reduces global warming . He spoke ...
