I can understand that. The problem with this kind of science is that you actually have to believe the scientists, no-one other is capable of having a relevant opinion. It's exactly like a dentist. Why ask anybody who's not a dentist why your tooth aches? If all climate scientist in the world (minus a handful who've been showed to be funded by the fossile industry and whose studies have ALL been found to be flawed) agree, the sane and responsible thing to do is to take their word for it.
