What makes it so that Meteorologists can't accurately predict the weather a week into the future, but climatologists can accurately predict 20, 30, even 100 years into the future?

Question for you:

Roll a pair of dice, over and over. Can you predict what the next few rolls are going to be? Obviously not. Can you predict what the average roll will be over the next 1000 rolls? Quite precisely, yes.

Weather and Climate is similar, albeit a lot more complex. The short term, heavy fluctuations, often on a time scale of hours to days, make up what we call weather. Over longer timescales, these fluctuations average out, resulting in relatively stable values that we call climate. However, unlike a good pair of dice, climate can change over time, usually very gradually, currently a bit faster than we feel comfortable with.
