While I do not have a degree in Climatology I did work with the State Climatologist of New Jersey for a summer while pursuing a degree in Meteorology at Rutgers, not that it means anything. :-)
So here's my expert contribution:
While global warming 'might' be occurring (I say might because in geologic time 50 or 100 years is merely a spit in the ole' bucket) I do not see it as a problem that humans can, in all reality, either control or significantly influence. Mother Earth certainly retains that province. And, within her sphere of influence, there are patterns that have been observed over long periods of time. (I'm going to cut a lot of meteorolocal details here in the interest of not globally warming this particular thread. :-) :-) ) The bottom line is... and *this* has been clearly observed in the past... that as the earth, or more specifically the Northern Hemisphere, warms to the point of losing substantial polar ice, a mechanism that has, again, in the past, been at the root of glacier formation and extreme winters in general kicks in. This rapidly(geologically speaking) cools the Northern Hemisphere. IOW, it precipitates an Ice Age. One extreme leads to another. We 'may' be influencing the earth's warming rate. But we are certainly *not* the master of it's climate.
