The ancient reserves of methane gas seeping from the melting Arctic ice cap told CHANS-Net member Jeff Chanton and fellow researchers what they already knew: As the permafrost thaws, there is a release of methane, a powerful greenhouse gas that causes climate warming.

The trick was figuring out how much, said Chanton, the John W. Winchester Professor of Oceanography at Florida State University.

Early human activity has left a greater footprint on today's ecosystem than previously thought, says a CHANS-Net scientist working with colleagues at the University of Pittsburgh and in the multidisciplinary Long Term Ecological Research (LTER) Network, created by the National Science Foundation to investigate ecological processes over long temporal and broad spatial scales. Highlighted in the June issue of BioScience, the study shows how historic human actions caused changes in nature that continue to reverberate throughout present-day ecosystems.
