In this experiment, students investigate the importance of carbon dioxide to the reproductive growth of a marine microalga, Dunalliela sp. (Note that the directions are for teachers and that students protocol sheets will need to be created by teachers.)

This animation illustrates how the hardiness zones for plants have changed between 1990 and 2006 based on an extensive updating of U.S. Hardiness Zones using data from 5,000 National Climatic Data Center cooperative stations across the continental United States.

This video follows biologist Gretchen Hofmann as she studies the effects of ocean acidification on sea urchin larvae.

This is the first of three short videos showcasing the dramatic changes in Alaska's marine ecosystems. This introduction to the impacts of climate change in Alaska includes interviews with Alaska Natives, commentary by scientists, and footage from Alaska's Arctic.

This interactive tool allows viewers to explore, by county, the areas of California threatened by a rise in sea level through this century.

This video discusses observations of two key warning signs of global change effects on the Southern Ocean: changes in Antarctic bottom water and ocean acidification.

This video production is a part of a four-panel report from the National Academies' America's Climate Choices project. The video maps out the realm of our accumulated knowledge regarding climate change and charts a path forward, urging that research on climate change enter a new era focused on the needs of decision makers.

This PBS video focuses on sea level rise in Norfolk, Virginia and how the residents are managing the logistical, financial and political implications. Science journalists who have been studying Norfolk's rising sea level problems are interviewed, as well as local residents who are being impacted.

This visualization explains in simple and easy-to-understand visuals the causes of sea-level change.

This video provides a comprehensive introduction to the role of coral reefs, the physiology of corals, and the impacts of both ocean warming and acidification on coral survival. It highlights experts from the Bermuda Institute of Ocean Sciences and the University of Miami.
