Debate? You see, that is the problem. Climate change is an event, like earthquakes, the sun rising, and cargo ships running into a pier. It is not like a gun control debate or an abortion debate where opinions matter. Climate change simply happens.
True, now tell that to all those lunatics that say it is human made for certain, and never debate (oh well, there should be a debate) how to deal with a natural climate shift, but just say we must do this or that to prevent it (like it was assured that we can prevent it).
The reason people are suspect when they criticize the overwhelming evidence that exists right now is because there are substantial political and corporate interests that support framing it as uncertain or as a debate.
The same reason goes for all those mediocre scientists (the vast majority of them) who could never dream of topping the bill if there wasn't some heavy controversial and popularized debate like this. If there is no debate, it is because every thing that happens is dismissed as "it's all according to the models", yeah, how could it be differently? There are literally thousands of different models, predicting all and its contrary. But, yes, it is an event and there must be no debate, because it is certain and all according to the models. Mind you, I believe (that's the correct term) that there is a climate change, but everything beyond that is just to early to call.
