Climate change and permafrost thaw alter greenhouse gas emissions in northern wetlands

icted. But over time high methane emissions will balance or outweigh the reduction of carbon in the atmosphere.

Not all ecosystems underlain by permafrost will respond the same way, Turetsky cautioned. It will depend on the history of the permafrost and the nature of both vegetation and soils.

What is clear, she said, is that not even northern ecosystems can escape the wide reach of climate change.
