This short video clip summarizes NOAA's annual State of the Climate Report for 2009. It presents a comprehensive summary of Earth's climate in 2009 and establishes the last decade as the warmest on record. Reduced extent of Arctic sea ice, glacier volume, and snow cover reflect the effects of rising global temperature.

Students will work with short-term and long-term air temperature data in order to better understand the differences between weather and climate.

This online quiz tests knowledge about climate change, its impacts, how we know about earth's climate, and potential solutions.
