People can deny the idea of global warming all they want, but as the climate changes so do the weather patterns...and I have witnessed a MASSIVE change in that where I live in just the last 28 years or so. When I was a little girl we would get snow pretty much from November till mid March, sometimes light, but for the most part it was the big, gorgeous, drifting, snowbank making storms. Now we're lucky if we have 3 or 4 major snowfalls in a season...and usually they don't even start until mid January. Just take a look at the weather, compare the differences between now and 30 years ago...then come back and tell me that the climate isn't changing.
Sorry, but if people really paid attention to the world around them they would see the changes...but such is the self-centered nature of the majority of human beings.
