From a reader:

I just checked current tropical storm conditions online (http://www.wunderground.com/tropical/). Here we are at the end of September and there’s nothin’ cookin’ in the way of tropical storm formation anywere in the Northern Atlantic. Surely this fact can be twisted and contorted in some way to show that this (lack of) development can somehow be attributed to global warming – surely. I need to hear an explanation from a scientist (even a botanist will do).
