Limits of Climate Science

The problems presented by climate modelling are very serious and are known to be very serious. It is mathematically impossible (and always will be) to create precise climate models because there are too many unknown and estimated variables involved in the equations (it is called a chaotic or nonlinear system). Only probabalistic estimates are possible. Note that this is why anyone who professes certainty about the future of the climate is a liar or hopelessly ignorant about the issue, regardless of which side he is on--these mathematical issues are not points of contention, they are an obvious fait accompli. Some question how accurate these probabilities are and this is a legitimate (perhaps the most legitimate) line of skepticism. Most climatologists believe the probabilities incline toward the theory that certain gases warm the atmosphere and they primarily focus on trying to calculate how much warming is likely to result, not whether warming will result. The balance of evidence I have seen leads me to agree with these scientists.
