This lesson plan has students working in small groups to research the Mountain Pine Beetle in Colorado and other inter-mountain Western states. Students identify the factors that control pine beetle population and research how warmer winters and decreasing spring snowpack allow the population of pine beetles to expand.

This video documents the challenges that climate change presents for four specific Arctic predators: polar bears, Arctic foxes, beluga whales, and walruses.

This video features residents of Shishmaref, Alaska, plus environmental journalist Elizabeth Kolbert and scientist John Holdren, exploring the human impacts of global climate change.

This video highlights a team of scientists who work on reconstructing the mass extinction that occurred 250 million years ago, the end of the Permian Period. This event wiped out the majority of life on our planet, resetting the evolution of life. Clues suggest that deadly bacteria might have set off a chemical chain reaction that poisoned the Permian seas and atmosphere.

This video on phenology of plants and bees discusses the MODIS satellite finding that springtime greening is happening one half-day earlier each year and correlates this to bee pollination field studies.

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

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 teaching activity addresses environmental stresses on corals. Students assess coral bleaching using water temperature data from the NOAA National Data Buoy Center. Students learn about the habitat of corals, the stresses on coral populations, and the impact of increased sea surface temperatures on coral reefs. In a discussion section, the connection between coral bleaching and global warming is drawn.

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.
