For an overall look at the 2012 Hurricane Season I recommend Jeff Masters’s Summary.
I said ‘weird’ and he says ‘bizarre’ but the tropical storms this year didn’t act like they should have. The track forecasts were really good this year, no matter what the Republicans may think. The problem was the wind speeds were much lower, and the storms much bigger that would be expected. The storm surges were higher than normal for the category of the storms, and the pressures lower.
While Issac provided some drought relief in the Mississippi Valley, its effects didn’t last, and barge traffic on the river may end at any time without significant rainfall over the system. On the Missouri they are limiting flow to preserve water for irrigation, industry, and drinking, but if the barges stop, they may have the water to grow crops and make things, and end up with no good way to ship them to market. Meanwhile the coasts are getting more rain than they want.
The climate isn’t governed by what people believe, it is governed by atmospheric conditions. Global climate change is here, and people need to start taking drastic action, because it is decades too late for gradual solutions.
