Another positive feedback. I think Guy McPherson has given up counting the.
"N2O is a strong greenhouse gas, almost 300 times more powerful than CO2 for warming the climate. With an atmospheric lifetime of 110 years, nitrous oxide is recognized as a particularly robust contributor to climate change.
"It causes two types of atmospheric damage ~~ not only is N2O a greenhouse gas, but it's also an ozone destroyer, because the process that removes nitrous oxide from the atmosphere also depletes ozone."
Thawing permafrost will release powerful greenhouse gas nitrous oxide
New research shows nitrous oxide emissions from the warming Arctic are much greater than previously thought, and will add to climate change and damage the ozone layer. Andrew Masterson reports.

Thawing ground inside the Arctic circle could release as much nitrous oxide (N2O) into the atmosphere as tropical rainforests – previously the biggest known natural emitter of the powerful global warming gas.
