Quote from futurecurrents:
But CO2 is a greenhouse gas and it's levels have gone up 40% over the last two hundred years mostly from the burning of fossil fuels. These are indisputable facts.
So what? Where's the data that says 40% has any impact? How do we know that 400% would have an impact measurable on a geological scale?
I'm not arguing with you on greenhouse gas qualifications or the amount CO2 has gone up (I don't know enough about it to say either way).
