Don't you know that dropping temperatures prove global warming?

"Don't you know that dropping temperatures prove global warming?"
Don't laugh. I've actually heard people try to make that arguement.
Global Warming is an unfalsifiable hypothesis. All observations confirm it, at confidence level of 100%. I suggest that it is the only scientific theory we need, any that contradict it are false (heresy) and any that agree with it are superfluous.
