No. It doesn't take a scientist to realize that, when you're talking about a complex system that is billions of years old, a hundred years or so worth of data is meaningless.
It doesn't take a scientist to realize that the Earth has always experienced heating and cooling periods, all of which pre-date human industrial activity.
It takes common sense, something that most of these research-dollar starved "scientists" are grossly lacking.
There are also freeper meteorologists who don't believe in "global warming." And some very prominent mainstream scientists, including Dr William Gray and Dr Kary Mullis. Also, I believe it is incorrect to say that the majority of scientists accept it, I believe that the majority of them do not. More likely, it is a majority of politicians, not scientists, who are pushing global warming.
Earth's temperature is up .7 degrees over the last 100 years, which is to say that the difference is so slight that it's probably less than errors in measurement. However, in the last 30 years, there has been a cooling trend. The earth has generally been warmer the last couple thousand years than it is now.
Theories of global warming are based on computer models that speculate on what could happen in the future (it has not happened yet) if increased carbon is placed into the atmosphere. However, there is at least one study showing that the United States, at least, is removing more carbon from the atmosphere than it puts in, this due to extensive reforesting - tree farms planted in pursuit of profits from paper manufacturing.
