You got it: global warming.
Global warming was the cause of too many hurricanes, and also the lack thereof. In fact, says David Freddoso at National Review, Global warming is now invoked as the cause of almost everything--including things that are entirely opposite one another:
We know the possible consequences of tinkering with our environment, causing unprecedented changes. This is how we approach the subject of man-made global warming. Wherever there is change, we turn immediately to global warming to explain it. Heat and cold, drought and downpour, famine and plenty — all can be caused by global warming. It can cause more foliage and less foliage; a slower-spinning earth and a faster one; more snow and less snow; a sun-scarred desert world, or a new ice age. Climate change makes mountains grow and it makes mountains shrink.Want to know how many different things are explained by global warming? Try going here.
It is not impossible that all (or at least most) of these theories are simultaneously true. But they also have the advantage of making global warming an unfalsifiable theory. Not only can no possible event disprove it, but it can actually serve as an explanation for any natural event worthy of note.
I'm just waiting for all those people who talk about how science must be falsifiable to denounce global warming as a pseudo-science.
