Climate change initiatives have to deal with, yes C02 (carbon dioxide), but methane has to be dealt with as well. Some scientists think a frightening climate tipping point will occur when permafrost melts, releasing deeply held methane.
The EPA said ...
Methane (CH4) is a greenhouse gas that remains in the atmosphere for approximately 9-15 years. Methane is over 20 times more effective in trapping heat in the atmosphere than carbon dioxide (CO2) over a 100-year period and is emitted from a variety of natural and human-influenced sources. Human-influenced sources include landfills, natural gas and petroleum systems, agricultural activities, coal mining, stationary and mobile combustion, wastewater treatment, and certain industrial process.
