Document Summary

Intro to climate change: weather is the state of the atmosphere (temp, humidity, precipitation) in a particular location during a short period of time. Time averages conditions of the atmosphere over a short period of time (hours) Fluctuates greatly and is dif cult to predict: what we get, measurements of conditions over a short time will de ne weather. Climate is the time averaged weather in a given geographical region (conditions of the atmosphere over relatively long periods of time: much more stable and easy to predict, what we expect. The average of the conditions over a long period will de ne climate. Both measures use the same variables (temperature), but their difference is the time scale. Global climate change: statistically signi cant changes in earth"s climate occurring over a time scale of centuries or decades. Measured as the surface temperature of the land and ocean. Graph represents the mean surface temperature, and any deviations from this mean.
