This activity engages learners in exploring the impact of climate change on arctic sea ice in the Bering Sea. They graph and analyze sea ice extent data, conduct a lab on thermal expansion of water, and then observe how a scientist collects long-term data on a bird population.

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 interactive map allows the user to explore projected alterations of land surfaces in coastal communities, based on different scenarios of sea level changes over time.

This very short video introduces the concept of sea level rise and ties it back to global warming. The video is brief, basic, and clear. It can be used for a quick introduction, but nothing deeper than that.

Students use long term sea-level rise data set to create models and compare short-term trends to long-term trends. They then determine whether sea-level rise is occurring based on the data.

This video features Katharine Hayhoe presenting a lively discussion of impacts that the Midwestern US is experiencing due to climate change. It steps through evidence for how climate change is affecting agriculture, tourism, drought and flood, water cycles and freshwater availability, the spread of invasive species and disease, as well as other topics.

C-ROADS is a simplified version of a climate simulator. Its primary purpose is to help users understand the long-term climate effects (CO2 concentrations, global temperature, sea level rise) of various customized actions to reduce fossil fuel CO2 emissions, reduce deforestation, and grow more trees. Students can ask multiple, customized what-if questions and understand why the system reacts as it does.

This video describes how field research -- in this case, making water measurements in rugged mountain locations -- helps us to understand the complex relationships among changing climate, populations, and water usage.

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

The video offers a simple and easy-to-understand overview of climate change. It poses basic questions such as 'What is it?' and 'How will it effect us?' and effectively answers those questions.
