climatology is still a relatively new science, and many (along with leftist media) are trying to make long term assumptions based on limited data (20-30 years or so). They like to come up with possible causes, and completely ignore the probable/likely causes...
Truth of the matter is, for years of dramatic climate climate, there's always a major natural event preceding them; whether it be varying solar activity, major volcanic eruptions, or a dozen other things that can severely impact weather.
Given that historical records and witness accounts of such occurrences pre-date the industrial revolution by hundreds or even thousands of years, any logical sane mind should come to the same conclusion...
That man made climate change is complete and utter horse shit...
