In this video, scientist Dr. Susan Prichard discusses the impact of pine bark beetles on western forests. She explains how climate change, specifically rising temperatures, is exacerbating the problem.

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.

This video examines the thawing of permafrost due to changes in climate and shows examples of the impacts that warming temperatures have on permafrost in the Arctic, including the release of the greenhouse gas methane. Dramatic results are shown, including sink holes forming on the landscape and beneath buildings, roads, and other infrastructure, causing some communities to relocate.

This video highlights specific climate change-related phenomena that are threatening the flora and fauna of Yellowstone National Park.

In this video, several scientists identify and describe examples of increasing health problems that they believe are related to climate change.

This video and accompanying essay review the impacts of rising surface air temperatures and thawing permafrost on ecosystems, geology, and native populations in Alaska.

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

In this video scientists discuss possible rates of sea level rise, storms and resulting damage, rising temperatures and melting ice, and their collective effects on ecosystems.

This narrated slideshow describes the impact of sea level rise on Tuvalu, one of the low-lying island nations in the South Pacific. As the frequency and intensity of floods and cyclones increases, the island is shrinking and saltwater intrusion is affecting local food production on the plantations. As a result, many residents are moving off the island to New Zealand, where they face major cultural changes.

This is a photo essay linked to a New York Times story about climate-related stressors on forests -- including mountain pine beetles, forest fires, forest clearance, and ice storms -- and the importance of protecting forests as an important carbon sink.
