If you think any of the preceding facts can falsify global warming, you're hopelessly naive. Nothing creates cognitive dissonance in the mind of a true believer. In 2005, a Canadian Greenpeace representative explained “global warming can mean colder, it can mean drier, it can mean wetter.” In other words, all weather variations are evidence for global warming. I can't make this stuff up.
Global warming has long since passed from scientific hypothesis to the realm of pseudo-scientific mumbo-jumbo.
Karl Popper in the 1930’s famously argued that Freudian Psychology failed this test, it was an ideology rather than a scientific theory. Who is the Karl Popper for today?
An hypothesis is simpler than a theory, it is a unitary falsifiable assertion. The assertion, “All swans are white.” is false and falsifiable. Whether or not it is true, it does not explain other observations about swans, or make any predictions beyond predicting any swans observed in the future will be white.
General Relativity famously accounted for the precession of the perihelion of Mercury (past observation) and successfully predicted the deflection of starlight by the sun during an eclipse. But GR is more than a series of hypothesis, it is a coherent (and validated) model of reality.
Global warming has long since passed from scientific hypothesis to the realm of pseudo-scientific mumbo-jumbo downright damned foolishness.
There -- fixed it.
