    Here Peter Raymond et al. examine carbon export by the Mississippi River in the form of inorganic carbon, the byproduct of natural rock-weathering processes that consume atmospheric carbon dioxide. Analyzing century-long records from the water-treatment plants of New Orleans, they find that shifting agricultural practices have had a greater impact than climate change on this carbon flux. Emilio Mayagora discussed the paper in a News and Views article (http://www.nature.com/nature/journal/v451/n7177/full/451405a.html), which we reprinted in this month's Nature Reports Climate Change (http://www.nature.com/climate/2008/0802/full/451405a.html).
