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 projected out to 2100.

This video features changes in the land, sea, and animals that are being observed by the residents of Sachs Harbour, Northwest Territories, Canada â many of whom hunt, trap, and fishâbecause of their long-standing and intimate connection with their ecosystem. Scientists interview the residents and record their observations in order to deepen our understanding of climate change in the polar region. Background essay and discussion questions are included.

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

A short video on the causes of ocean acidification and its effects on marine ecosystems.

This carbon calculator, developed by the EPA, guides students in calculating their carbon footprint and then using that information to make decisions about how to reduce their carbon emissions.

A short video on how changing climate is impacting the ecosystem and thereby impacting traditional lifestyles of the Athabaskan people of Alaska.

This slideshow lays out a photo story with short descriptions of how designers of city buildings all over the world are taking climate change and rising sea level seriously.

A simple three-part diagram from UNEP GRID Vital Water Graphics showing how global warming could impact coastlines and populated areas of Bangladesh with a 1 and 1.5 meter sea level rise relative to the current coastline.

This is a slideshow without audio about the effects of sea level rise on a Louisianan coastal community - the Isle de Jean Charles -- and focusing on the human impact of disappearing land.

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.
