  2. Commonly Accepted Definitions refers to the current atmospheric conditions (including temperature, precipitation, wind, humidity, barometric pressure) at a particular time and place. • Weather • Climate refers to the general weather patterns expected in a given area (sometimes based on the 30 year average weather). Climate may also be applied more generally to large-scale weather patterns in time or space (e.g., an Ice Age climate or a tropical climate). Or, in the words of a middle school student…. "climate tells you what clothes to buy, but weather tells you what clothes to wear."

  3. What tools do scientists use to study past, present, and future climates? • Past – • Present – • Future – • Recent past – weather records • Distant past – ‘proxy data’– fossils, ice cores, tree rings, pollen Sensors on satellites, sensors on towers Computer models

  4. Globally-averaged temperature over the past 140 years

  5. Concentration of Carbon Dioxide (CO2 ) Mauna Loa, Hawaii

  6. Between 1990 and 2100 global temperature are likely to rise 1.7 to 4.9 C (3.1-8.9 F). • Likely effects: • Droughts • Extreme storms • Wildfires • Vegetation changes • Melting ice • Rise in sea level
