Unfortunately, current weather disasters across the world too often deepen the convictions of both the human activity enhanced climate change deniers (arguing that such disaster clusters have occurred in cycles in the past) and believers (arguing that the strength and recurring frequency of these disasters during recent years illustrate an unnatural pattern that human activity is to blame).  

The believers have the better case but this fact is obscured because too many on both sides conflate weather and climate in the current debate regarding the significance of these current events.

The real focus of attention should be on the deviation from historical cyclical trends since the beginning of the Industrial Revolution & the rapid acceleration of this change over the past 4 decades or so.  Current events add data supporting the thesis that this accelerating change is occurring but (being essentially weather events) prove nothing in isolation.
