Methane (CH4) is a hydrocarbon and an important greenhouse gas.
According to the IPCC’s Fourth Assessment Report in 2007, methane has a global warming potential 25 times stronger than carbon dioxide.
In general, methane is produced from:
- anaerobic (without oxygen) decomposition of waste in landfills
- animal digestion
- coal production
- decomposition of animal wastes
- incomplete fossil fuel combustion
- production and distribution of natural gas and petroleum
Positive Feedback Loop
There is an important climate feedback
regarding methane gas.
Notably, as temperatures rise worldwide, permafrost in both Northern Canada and Siberia will melt which will cause huge amounts of methane to be released into the atmosphere
Since methane is a greenhouse gas, this will cause even more global warming
which will further enhance the melting of permafrost.
