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.

This lesson explores the chemistry of some of the gases that affect Earth's climate. It is the 3rd in a series of 9 lessons from an online module entitled 'Visualizing and Understanding the Science of Climate Change'.

This video discusses the differences between climate and weather by defining and presenting examples of each. When presenting examples of weather, the video focuses on severe events and how meteorologists predict and study the weather using measurement, satellites, and radar. The climate focus is primarily on an overview of climate zones.

This video describes how Colorado has planned for and uses clean energy resources to reduce its carbon footprint.

In this video from the Polaris Project Website, American and Siberian university students describe their research on permafrost.

This video takes viewers high into the Rocky Mountain snowpack, where researchers dig snow pits to explore the source of Colorado's water supply. Highlights how important snowpack is to the supply of fresh water available in western and southwestern states. Snowmelt dynamics are discussed, including the impact of a warming climate on these dynamics.

In this activity, students distinguish between directly and indirectly transmitted diseases and participate in a group game to simulate the spread of vector-borne diseases. They then research a particular pathogenic disease to learn how global warming and biodiversity loss can affect disease transmission.

This static graph of changes in CO2 concentrations goes back 400,000 years, showing the dramatic spike in recent years.

This activity is the first of five in the High Adventure Science Energy module and focuses on sources of electricity in the US by state as well as consumption in the US by sector and globally per capita.

This introductory video covers the basic facts about how to keep residential and commercial roofs cool and why it is important to reducing the heat island effect and conserving energy.
