are you trying to make a claim that man has no influence on our ecosystem or climate change? Or are you just trying to paint Obama as a liar?
I think what he is pointing out is the fact that the science is far from settled, and the dissenting science is not being evaluated. How can you make a logical summary if only 1/3 of the input is considered. But yes, Obama is a liar.
And you are wrong on all counts. The science is settled, the absorption spectra of the GHGs have been known for over 150 years. We have increased the amount of CO2 by over 43%, have increased the amount of CH4 by over 250%, and added industrial gases which have no natural analog, and are as much as 1700 times as effective a GHG as CO2.
Virtually the whole of the scientific community accepts that we are raising the temperature of the planet. Where there is controversy is how much of the observed warming is anthropogenic in origin. And controversy as to the speed of the warming, and what the effects of the warming will be.
