We have nothing to do on that question. This is not our business.
Are people arguing in their daily life of the relevance of using ethanol as a solvant in an organic synthesis? No of course not! They don't give a fuck and even if they'd do they know they don't have the skills required to understand fully the process. They let this question for the chimists.
So why don't we just stop discussing climate change and listen to the scientists results?
I don't know about you, but I am educated enough in science to know that man made climate change is complete horse shit. One or two big volcanic eruption puts more CO2 into the atmosphere than all of humanity ever has. I don't have to believe in tinkerbell because I know it is a fairy tale. You keep clapping your hands though if it makes you feel like you are doing something.
Seems like you're not. This why you shouldn't talk about things you don't have a clue about.
"Our studies show that globally, volcanoes on land and under the sea release a total of about 200 million tonnes of CO2 annually. " http://hvo.wr.usgs.gov/volcanowatch/archive/2007/07_02_15.html
the global fossil fuel CO2 emissions for 2003 tipped the scales at 26.8 billion tonnes
It means it would take 1000 years of eruption to compensate one year of human made CO2.
But please, continue to show us how educated you are.
