Among the worrisome environmental effects of global warming is the thawing of Arctic permafrost---soil that normally remains at or below the freezing point for at least a two-year period and often much longer. Monitoring changes in permafrost is difficult with current methods, but a study by University of Michigan researchers offers a new approach to assessing the extent of the problem. The new study approach, which relies on chemical tracers in stream water, is described in the journal...
