Not exactly.
The atmosphere and enviroment are very complex. Mostly, nobody really knows what's going to happen and why. 30 years ago scientists were predicting the next ice age was right around the corner. What scientists have to say today are really best guess predictions, with very little hard science. We simply don't know.
Also, statics used to measure the changes are highly suspect. Temperatures were not always measured by satellites, and much of the historical data is measured at ground stations in or near to large cities. This could have a huge impact when you consider the size and population density a huge gathering of humans has on the immediate area. New York, a fairly small state shows temperature increase in NY city, but in a smaller city only 80 miles away a slight decrease over the past 15 years. Shouldn't "Global Warming" apply globally? How can there be such a discrepency only 80 miles apart?
