In true science when the predictions of the theory fail to match the observed data, then the theory is rejected. However, the man caused CO2 driven theory of global warming is rooted in politics not science so it cannot be rejected. Finally people are realizing that all the predictions of global warming have not come true especially as we experience another round of polar vortexes.
The politics of Federal additional taxation without the science to back it up.
That is why the EPA refuses to release to Congress the methodology of how it determined the significance of CO2 to "Glow-Bull" warming,
because there is no science to back it up - just Obama politics !
