That article says the study found that grazed beef release more carbon than the carbon offset by soil sequestration. It doesn't say it releases more carbon then grain-fed, and actually, while I haven't read the source study, the general implication in the article seems to lean toward grazed beef releasing less than grain-fed (just not, according to the researchers, enough less to be carbon-neutral).
