Actually around 97% of climate scientists do make such claims.
That claim itself is excellent example of the nonsense that gets repeated in the media but is basically false. The 97% refers to a study where a group of scientists were asked if GHGs contributes to warming - a statement that I also agree with. What makes it false is people like you try to take a response to a very narrow question and use to claim that any alarmist statement is equally supported by scientific evidence.
And honest debate requires that every individual claim be evaluated on its own. i.e. if someone claims that warming is causing hurricanes then we need to the look at the evidence for that claim. The fact that GHGs cause warming has no bearing on whether that particular claim is correct or reasonable.
