Now much change

There is a leveling off after "W" took office and Cheney released his energy report. It was that report that destroyed aspects of the clean water act that would have prohibited horizontal drilling.

Methane (CH4) (click here) Methane is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from livestock and other agricultural practices and by the decay of organic waste in municipal solid waste landfills.

Enteric fermentation which was discussed last week and manure management are 35% of methane emissions.

Methane can be reduced and captured by altering manure management strategies at livestock operations or animal feeding practices. Learn more about EPA's AgSTAR Program.

So while The amount of Methane is only 16 % of all greenhouse gas emissions according to the ipcc in 2015 (the graph below). There is an CO2 equivalent that must be accounted for: every methane molecule is the equivalent of 25 carbon dioxide molecules.

When that is viewed correctly, the percents of CO2 equivalents change dramatically and methane is a very big threat.

Methane 16 percent by volume X 25 it's CO2 equivalent = 400

If the graph to the right (click here) were to reflect only CO2 and CH4 (methane) the appearance changes dramatically since CO2 is currently 65 percent by volume.

The bottom graph to the right is accurate to 2010.
