Did James Hansen Unwittingly Prove The Null Hypothesis Of AGW?

Hansen limited his research and climate models to human causes of climate change. He made two projections that argued CO2 would continue to increase. In doing so, he predetermined the outcome. He confirmed his hypothesis that continued human production would cause global warming, but only in the models. However, apparently driven by his political agenda, he had to convince politicians that a reduction in CO2 output would solve the problem. To do this, he ran his model to show what happens with no CO2 increase. It produced a curve that fits the actual temperature trend in the intervening 27 years. This is the result you expect if you accept the null hypothesis that CO2 from any source is not causing global warming.
