Hardly anybody is qualified to build or interpret climate models. We are all beholden to what the experts say. Even if a layman sets out to study the competing claims of climate scientists carefully, he still is pretty much restricted to comparing theories/conclusions and has a hard time critiquing their underlying methodologies systematically by measuring them against experience.The "experts" want you to be beholden to what they say and Peter has closed his eyes and walked blindly into their trap.
Virtually all of climate science is based on typical everyday experience and a few minor and easily understood bits of physics. We've all noticed that sunlight (also called visible radiation) makes objects warmer when it strikes them and that when those heated objects are moved out of the sun they begin to cool but we can't visibly see the warmth emanating from them. We've all noticed that hot air rises (in a hot-air balloon, thermal, etc.) and that when the hot air is also moist (humid) that clouds form when it cools sufficiently as it rises. Etc., etc.
The climate is difficult to predict not because the physics is difficult, but because it is so chaotic. All the bits of earth, ocean, and atmosphere heating and mixing at different rates and interacting with each other produces really, really complex responses that are impossible to characterize analytically. So scientists make statistical climate models to try and mimic the past and predict the future. They are really little more than software hackers and statisticians and know little more science (physics) of relevance to their task than the average layman.
So no, we aren't beholden to the priests of warmenism unless we want to be.
