Yea, both methane and CO2 have natural and man-made emission sources. However, the emission rate of methane is significantly lower than that of CO2. Also, the chief warmer among them all is water vapor but we've got no control over that.
Thanks for taking the time out to read my piece.
Always a pleasure, @gentleshaid. Thanks for your response.
As a major producer of natural gas, the U. S. is responsible for releasing a lot of methane into the atmosphere. Many people don't pay attention because it's not carbon dioxide.
