This clickable visualization demonstrates the catastrophic effect that follows the removal of a key producer or consumer in the Arctic food chain.

The Climate Momentum Simulation allows users to quickly compare the resulting sea level rise, temperature change, atmospheric CO2, and global CO2 emissions from six different policy options: 1) Business As Usual, 2) March 2009 Country Proposals, 3) Flatten CO2 emissions by 2025, 4) 29% below 2009 levels by 2040, 5) 80% reduction of global fossil fuel plus a 90% reduction in land use emissions by 2050, and 6) 95 reduction of CO2 emissions by 2020). Based on the more complex C-ROADS simulator.

This video is the second of a three-video series in the Sea Change project, which follows the work of Dr. Maureen Raymo, paleogeologist at Columbia University's Lamont-Doherty Earth Observatory, who travels with fellow researchers to Australia in search of evidence of sea level that was once higher than it is today.

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.

This animation demonstrates the changing declination of the sun with a time-lapse animation. It shows how the shadow of a building changes over the course of a year as the declination of the sun changes.

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

This video profiles the Arctic Inuit community of Sachs Harbour and its collaboration with scientists studying climate change. Changes in the land, sea, and animals are readily apparent to the residents of Sachs Harbourâmany of whom hunt, trap, and fishâbecause of their long-standing and intimate connection with their ecosystem. Scientists from a climate change study project interview the residents and record their observations. The scientists can use these firsthand accounts along with their own collected data to deepen their understanding of climate change in the polar region.

This interactive contains four animated slides that introduce the greenhouse effect. An additional animation offers to 'explore more'.

Video presents a broad overview of what (NASA) satellites can tell us about how climate change is affecting oceans.

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.
