The change in the weather in 2012 is not weird but as a result of global warming. There are changes that are going to take place in our weather pattern but all have to do with environmental degradation.
Its just a sign that we are in the midst if an El Nino weather pattern as opposed to the La Nina pattern that brought us so much snow and ice last winter. Possibly due to global warming but more likely just a natural cycling of weather patterns. NOT a sign that the end of the world is immanent so give it a rest already!
