I took a look at your link, and all you show is that CO2 concentrations are rising and temps are also rising (and results from rising temps).  That is called correlation.   Correlation is not causation, nor is it evidence.  Do you have any evidence that CO2 concentrations changing from 250ppm to 600ppm will result in X change in climate?  Lots have built models, but they are very weak evidence, as they are full of assumptions and unknowns.
