One thing it predicts (in general) is weather instability. Some places will be drier, and some will be wetter. The patterns we have come to rely on will change. However, I don’t know if it’s possible to extrapolate the effects down to specific incidences like this. It’s like the people who look at winter storms and say that global warming is invalid because winter exists. In this case, I’ve heard it’s a bunch of ice that’s damming things up that’s the problem, but not the absolute cause. In 1997, it was an abnormal thaw that did it. Proximal causes vary, so it’s hard to pin something like that on Global Warming/Climate Change, but the idea that we’d have instability and more abnormal events seems to be holding, um, water.
