There's no record and/or proof that man can predict global weahter 100 years in advance accurately yet you claim it is much easier than predicting short term weather fluctuations accurately. Interesting.

These are two different things. Short term forecasts are for the presence of local clouds/rain and local temperature. Climate change forecasts are for the temperature of the whole system given x input of sunlight and y concentration of heat trapping gas (basic physics). Because the system is effectively isolated, you can make pretty solid predictions on its state given various inputs. The only complications are the feedbacks present in the system, which may either mitigate or amplify the effects.

A simple analogy is turbulent water in a pipe. It's impossible to predict the pattern of water flow at any particular point for a reasonable length of time, but looking at whole system, you can tell where it's flowing.

So you're saying it's easy to predict weather 100 years from now? Anyway the poster I responded to explained his points and we moved on. I'm aware of the difference between climate and weather.
