Global warming is responsible for an alarmingly low amount of cyclone activity.

All snark aside, I would certainly not be surprised if there is global warming activity and that we are causing it. I proceed on the assumption that we are until proven otherwise, being the cautious person I tend to be when issues like potential global cataclysms come to the fore. But after hearing that cyclones and hurricanes would dramatically increase in number, thanks to global warming, this should show that we have not yet fully mastered the art of predicting what Nature will do. A little humility is in order.
