It may seem like a simple process of just looking at the temperature from year to year, but it is SO MUCH MORE than that! Our understanding of the global climate comes from a compendium of data including measured and tracked temperature, humidity, wind speed, and barometric pressure, spanning over 100 years of observation!! To study this massive amount of information and be able to surmise that the increasingly extreme and bizarre weather patterns are a result of human influence... it's truly an incredible accomplishment. So everyone who says during a blizzard "so much for global warming"... shut up. You're wrong.
