The permafrost carbon feedback
The world is on the cusp of a “tipping point” into dangerous climate change.
The Age: At the edge of disaster – The world is on the cusp of a “tipping point” into dangerous climate change, according to new data gathered by scientists measuring methane leaking from the Arctic permafrost and a report presented to the United Nations on Tuesday.
“The permafrost carbon feedback is irreversible on human time scales,” says the report, Policy Implications of Warming Permafrost. “Overall, these observations indicate that large-scale thawing of permafrost may already have started.”
