As far as global warming/climate change, I tend to agree with Eric. The climate of our planet is a massively complex system. To be able to accurately model the climate, we also have to accurately model everything that affects the climate. Not to mention we have historical records for what, 100 years or so? The rest of our records are deduced from ice core data. Take all that into consideration, and it seems rather presumptuous to think that we can accurately model the climate for the future.
We have a hard enough time making weather models that can predict the weather 1 week ahead of time (most of our predictions are made by taking a bunch of weather models and averaging out the results).

That being said, nothing seems too weird here(SC). Last 2 winters were pretty cold, but its happened before. Summer is always hot. Everyone always complains there isn't enough rain (seems to have more to do with el nino/la nina than anything).
