> so it should be much easier to predict right? Yes, because the goals of the forecast are different. A weather forecast seeks to predict a future position within the phase space of the system; a climate forecast seeks to predict the overall shape of that phase space. "It will be 1C warmer in February on average" is a useless prediction if I'm deciding whether or not to wear a heavy coat tomorrow, since day-by-day variability swamps that average. But it is a very useful prediction if I'm designing infrastructure that needs to last 50 years.
