  • Reasons for recommending:
    In a Nature News & Views article that we've reprinted this month (http://www.nature.com/climate/2008/0804/full/452162a.html), Sybil Seitzinger explains how this 'study of unparalleled scale' replaces a muddy mix of data on the ability of river sediment bacteria to convert nitrate pollutants into nitrogen gas and the the greenhouse gas N2O. It turns out that the more nitrates we load into rivers, the worse they sponge it up.
