Karl Popper -- widely regarded as one of the greatest philosophers of science of the 20th century -- claimed that only statements which are falsifiable can be considered scientific. So, a theory should be considered scientific if and only if it is falsifiable.
Now, consider global warming -- er, climate change. By Popper's definition, global warming cannot be science since its claims are unfalsifiable. The so-called science of global warming cannot be contradicted. Even evidence that obviously refutes its claims is disregarded -- the evidence is already incorporated into global warming.
At its most absurd, show that temperatures are going down and the adherents of global warming say that the lower temperatures are the result of global warming. It's almost Marxian in its nonsense.
In the end, global warming is something other than science. For many, it's another means to destroy man. For others, it's the ploy that will lead to riches. And for the politicians, it's one more crisis that can't go to waste.
note: Even while the global warmists are playing the adult masses, the public schools are indoctrinating the next generation. (HT LewRockwell.com)
