It is referring to the global warming potential. In other words emitting 1 ton of Methane warms the planet in a manner equivalent to 25 tons of CO2.
Remember, the fact that CO2 warms the planet is clearly established. The fact that methane does so at a rate 25 times as powerfully is also clearly established. The number of scientists who dispute this is Zero. It is not climate science, but rather basic chemistry.
The disputed aspect of climate change is not the chemistry, but rather whether the gasses emitted by humans has any but the most marginal affect on the overall temperature of the planet.
Denying the basic science behind the chemistry is akin to claiming the earth is flat.
CRAP!
First of all, I believe the word is gases.
What's in dispute? There has been nothing but cooling in this century regardless of CO2 levels. Thousands of summertime cool temperatures have been broken this year alone, not to mention snow in Israel and Baghdad and record cold temperatures killing wildlife in Tibet in recent winters, record ice formation in the Southern Hemisphere.
The amount of CO2 in the atmosphere (around .04%) amounts to a fart in a hurricane, and is an insignificant level regarding temperature retention.
Nitrogen and Oxygen make up 99% of the content of the atmosphere and thank God they are there acting as insulation (greenhouse gases) to keep us from alternately freezing to death at night and frying during the daytime.
99%...why aren't the Chicken Little morons screaming about the dangerous levels of Nitrogen?... Or the serious toxic tsunami of real pollution (visible from space) coming out of China and India?
The answer: Because it's not the US.
Remember, the fact that CO2 warms the planet is clearly established. ................

When the temperature monitoring equipment has been placed next to air conditioning compressors/heat exchangers and on blacktop parking lots they can't help but read higher.
There are two possibilities here. They were placed there by mistake or intentionally. If intentional, that speaks to global warming fraud. If by mistake, then they are too stupid to conduct valid, trustworthy science.
