This video shows the potential of dendrochronology (tree ring study) to shed light on climatic conditions of the past. Scientists at Columbia University's Lamont-Doherty Earth Observatory read the growth rings of ancient trees to understand the history and workings of the monsoon. In addition, historical accounts are correlated with data from tree rings to better understand these events.
This video explores the work of environmentalist John Hart, a Professor of Environmental Science at U.C. Berkley. In the Rocky Mountains of Colorado, Dr. Hart has established an experimental laboratory in which he has artificially created and maintained a 3-degree increase in surface temperature of a plot of land, and documented the impact on plant species occupying the plot.
Teaching Climate –This narrated slideshow describes the impact of sea level rise on Tuvalu, an island nation 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. Many residents are moving off the island to New Zealand, where they face major cultural changes.
In this video, students see how data from the ice core record is used to help scientists predict the future of our climate. Video features ice cores extracted from the WAIS Divide, a research station on the West Antarctic Ice Sheet.
In this activity, students research various topics about ocean health, e.g. overfishing, habitat destruction, invasive species, climate change, pollution, and ocean acidification. An optional extension activity has them creating an aquatic biosphere in a bottle experiment in which they can manipulate variables.
This interactive map from National Geographic shows selected geographic locations for a number of impacts of global warming (on freshwater resources, food and forests, ecosystems, etc). Impact overview is summarized for each highlighted impact.
