Climate change is a departure from the expected average weather or climate normals. The word is derived from the Greek root paleo- , which means "ancient," and the term "climate." Paleoclimate is that which existed before humans began collecting instrumental measurements of weather (e.g., temperature from a thermometer, precipitation from a rain gauge, sea level pressure from a barometer, wind speed and direction from an anemometer).
Instead of instrumental measurements of weather and climate, paleoclimatologists use natural environmental (or "proxy") records to infer past climate conditions.
