Thawing Permafrost Could Release Vast Amounts of Carbon and Accelerate Climate Change by the end of this Century
*New computer modeling study, led by a Berkeley Lab scientist, could help revise understanding of permafrost’s role in global warming*
Billions of tons of carbon trapped in high-latitude permafrost may be released into the atmosphere by the end of this century as the Earth’s climate changes, further accelerating global warming, a new computer modeling study indicates.
The study also found that soil in high-latitude regions could shift from being a sink to a source of carbon dioxide by the end of the 21st century as the soil warms in response to climate change. (more…)
