There is little to no scientific support of green house gases produced by humans as being significant to measure on a global basis, let alone causing global warming. Mt St. Helens spewed so much CO2 that was detected all over the world. For humans to match, our CO2 production would be have to increase at unrealistic exponential amounts.
There have been many ice ages, most of which existed before humans arrived - and these same people just ingore the little fact of Global Warming (even though there is no proof of current Global Warming) is a natural and repeating phenomenom that we can't do sheet about.
The whole environmentalist issue is just a facade to destroy our way of life. They can't get their way taking us head on, so they create fake issues and act like they are trying to make the world a better place, when in reality, they are just pissed off and bitter that we are the most successful country in the world in history. The more we prove them wrong, the more pissed off and angry they get....kind of like my ex-wife! LOL!! These socialists are angry that their ideas of society will never work and hate us slapping them in the face with success.
God bless America!
