SUMMIT COUNTY — Instead of absorbing heat-trapping gases, Arctic near-shore seas are becoming sources of carbon dioxide, accorindg to researchers from Sweden’s University of Gothenburg. With careful measurements, the scientists found that the amount of CO2 being absorbed by the oceans is decreasing.
That leads to an increase of greenhouse gases in the atmosphere and an increased rate of warming in the Arctic in a self-reinforcing climate feedback loop that includes some unexpected factors. For example, increased coastal erosion carries more organic matter into the sea, where it breaks down and releases even more CO2. (more…)
