But what is provable, documented and undeniable is that co2 does cause warming. There have been several events in our planets history where run away co2 warming has occurred. But the co2 levels were way higher than 400 ppm, more like 300,000 ppm in the case of snowball Earth.
I am a math and science kinda guy and I just go where the science takes me. AGW appears to me to be junk science, notice I said appears. Climate is to complex a system for humans to understand with certainty what will happen if X or Y changes by Z amount. So for the time being I am a man made global warming skeptic but I do not deny that co2 does cause warming. I just do not think man is putting enough co2 into the atmosphere to make much of a difference one way or the other.
the Sun which is a star , and which a million Earths could fit into does affect the Earths climate. without the Sun the Earth would be the temperature of interstellar space which is around -400 degrees . The earth is a cold little insignificant rock compared to the sun and the immensity of the universe. in your little brainwashed by the media minds you think that a gas that is 0.039% , that is 4 hundredths of 1%, of the atmosphere affects the Earth's climate . to do that this increase which is a percentage of that 0.039% would have to over come the Sun's influence which is a massive nuclear furnace , a star. you leftists can't fool someone that is an independent thinker. and yes i ‘ll tell you something that will hurt you more than anything :i am for freedom and I will never anything you say, nor believe your mainstream media , nor your stupid scientists , nor your gov agencies, so I am Republican. and I'm Republican for life . and i know that hurts you socialists more than anything that I remain Republican. nothing you can say can influence what I think
