I quite frequently see scientists directly quoted in news reports as saying that man-made global warming is "established scientific fact". Very rarely do they ever strike me as being interested in debating the issue and very rarely do I ever hear them say things such as "I believe it's a fact, but it's possible that I'm wrong."
There are skeptics on the subject to be sure, but you have to admit that they usually tend to be ridiculed.
The mechanics of global warming do occur. The differences all amount to the significance of the effects and what should be done. The warmists overstate the significance of the effects and often invent effects.
