We think of Florida or Aruba having a warmer climate, compared to Maine or Canada. > Weather is short term, whereas climate is long term. > As NASA explains: >> The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time. >> What is meant by “long periods of time”? Given the Earth’s age of around 4.5 billion years, one might think these long periods of time should be in the millions of years. But instead scientists look at averages over extremely short periods of time, e.g., 30 years.
