Hi Michael, It's no surprise that the history of our planet has shown dramatic weather changes for reasons which are still unclear to us today. I don't believe either proponents or opponents of the global warming hypothesis have enough evidence either way to prove or disprove their theories. And as usual, there are always multi-factorial causes for climate changes, of which, global warming may be a contributing factor. But what cannot be disputed is that homo sapiens have changed the landscape of our planet. It is the effect of these changes which are difficult to measure.
