This narrated slide show gives a brief overview of coral biology and how coral reefs are in danger from pollution, ocean temperature change, ocean acidification, and climate change. In addition, scientists discuss how taking cores from corals yields information on past changes in ocean temperature.

In this learning activity, students use a web-based carbon calculator to determine their carbon footprint on the basis of their personal and household habits and choices. Students identify which personal activities and household choices produce the most CO2 emissions, compare their carbon footprint to the U.S. and global averages, and identify lifestyle changes they can make to reduce their footprint.

This video addresses the impact of climate change on several butterfly populations. Warming temperatures lead to shifts in location of populations of butterflies or die-offs of populations unable to adapt to changing conditions or shift to new locations.

This animated visualization was created for the planetarium film 'Dynamic Earth'. It illustrates the trail of energy that flows from atmospheric wind currents to ocean currents.

This short video, the sixth in the National Academies Climate Change, Lines of Evidence series, explores the hypothesis that changes in solar energy output may be responsible for observed global surface temperature rise. Several lines of evidence, such as direct satellite observations, are reviewed.

This short video, adapted from NOVA, explains how Earth's position relative to the Sun might be responsible for the dramatic shift in the climate of what is now the Saharan nation of Djibouti.

This video from ClimateCentral looks at the way climate conditions can affect vegetation in the West, and what influence this has on wildfires. Drought and rainfall can have very different wildfire outcomes, depending on vegetation type, extent, and location.

As a segment in PBS's Coping with Climate Change series, Hari Sreenivasan reports on the actions the city of Chicago is taking to mitigate climate change in an urban landscape.

This video reviews how photovoltaic (PV) cells work, noting that technological innovations are decreasing costs and allowing PV use to expand.

This interactive world map shows the impact of a global temperature rise of 4 degrees Celsius on a variety of factors including agriculture, marine life, fires, weather patterns, and health. Hot Spots can be clicked on to get more specific information about the problems in different regions.
