CO2 and methane released from permafrost
Unexpectedly large amts of CO2 are released into the atmosphere as result of "feedback loops" that are speeding up natural processes...a cycle in which higher temperatures are beginning to melt the arctic permafrost, which could release hundreds of billions of tons of CO2 and CH4 into atm. Permafrost holds 1 trillion tons of carbon, and as much as 10 percent of that could be released this century. Melting permafrost also releases CH4, 25 times more potent a GHG than CO2.
