Rivers flow across many kinds of terrain, interacting with soil, rocks, microbes, and roots. River water therefore carries signatures of everything it interacts with, and its chemistry reflects the response of the critical zone—the region of the planet stretching from the tops of trees to the bottom of groundwater—to changing climate. River chemistry is likely to change with a warming climate, yet most climate-related research studies have focused on changes in river flow.
