Yep. At first a few rogue scientist find something new. Then that 'something new' gets peer reviewed, discussed about, put through scientific screening, whatever. After that a few rogue scientists do NOT think the scientifically model is correct enough. (or the other way around)
We now have a whopping 97% of scientists thinking the models of global warming and the human factor therein is correct. So at some point 97% of scientists did not believe that global warming existed and / or was man made. The scientific advance is that we now have models that imply global warming is real and man-made. Is that what you wanted to say?
