Well, clearly "hmmmm" doesn't have a degree in any of the sciences, or else he would know that the earth is very dynamic. Weather isn't as easy to predict as most people think. It's a hard job, so give the meteorologists a break will ya? People don't come to you belittling your job by saying "oh, all they do is guess, they don't know anything, probably just flips a coin and BOOM! gets paid for doing nothing."
