When it comes to science, you start with measurements, then you postulate a theory and if the theory is right it will predict the future measurements. It all comes down to measurements – and in the case of the Climate, the key measurement is atmospheric temperature. And the most accurate way to do that is to have a consistent satellite based radiometer. There is a satellite that measures lower tropospheric temperature and since 1979 it shows a rise of about 0.3deg C although in the last 11 years it has been steady.
So measurements do not support the theory – at least not so far. Maybe the theory is wrong? 
At face value, if it takes 30 years to increase 0.3deg, then it will take 200 years to increase 2deg. Not quite the immediate disaster we are told about. Or let me be pessimistic – look at the graph from 1993 to 2009 – it rose 0.48deg in that time. So at that rate it would still take 66 years to increase 2 deg. But looking at the trough to peak is not good math or good science – is that what the scientists have been doing?
The good news is that the public is finally waking up to this poor science. “Global warming” is more like a religion that people want to believe. The ether was once believed as a sure thing as the medium for radio waves – it HAD to exist – what other explanation was there? But then along came skeptical Einstein.
