This is why most scientists now refer to it as global climate change rather than global warming. The skeptics like to point out that fact and claim that it is a denial of the original global warming theory. In reality it is the same thing. On the average, worldwide temperatures have increased but that does not mean that every location on earth is warmer every single day. By the same reasoning, it does not mean that a cold winter in Chicago means that the entire earth is suddenly colder. The fact is that average world temperatures are on the rise.
