This article discusses how arctic bogs hold a global warming risk that could cause significant problems for us. As warming brings earlier spring rains in the Arctic, more permafrost thaws, releasing more methane in a difficult-to-stop feedback loop, research shows.
Increasing spring rains in the Arctic could double the increase in methane emissions from the region by hastening the rate of thawing in permafrost, new research suggests.
“Our results emphasize that these permafrost regions are sensitive to the thermal effects of rain, and because we’re anticipating that these environments are going to get wetter in the future, we could be seeing increases in methane emissions that we weren’t expecting,” said the study’s lead author, Rebecca Neumann, a civil and environmental engineering professor at the University of Washington. The study appears in the journal Geophysical Research Letters.
