Why are long-term weather forecasts less accurate?
BONUS: What does this have to do with the "butterfly effect"?
Weather models are better at predicting short-term weather conditions - we don't know how conditions may change.
BONUS: Something very small, such as a butterfly flapping its wings, could change the weather outlook.
