In this activity, students conduct a life cycle assessment of energy used and produced in ethanol production, and a life cycle assessment of carbon dioxide used and produced in ethanol production.

This PBS video focuses on sea level rise in Norfolk, Virginia and how the residents are managing the logistical, financial and political implications. Science journalists who have been studying Norfolk's rising sea level problems are interviewed, as well as local residents who are being impacted.

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

In this activity, students use Google Earth to investigate ideal features of wind farms.

This Changing Planet video documents scientists' concerns regarding how melting Arctic sea ice will increase the amount of fresh water in the Beaufort Gyre, which could spill out into the Atlantic and cause major climate shifts in North America and Western Europe. The video includes interviews with scientists and a look at the basics of how scientists measure salinity in the ocean and how ocean circulation works in the Arctic.

This video provides an overview of the research of the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) on converting biomass to liquid fuels.

This lesson is an investigation of the impact of climate change on the phenology of a variety of taxa, including migrating birds and hibernating animals in the Colorado Rockies. Students analyze 40 years of data collected by Billy Barr from the Rocky Mountain Biological Laboratory.

This is a global land surface air temperature graphic showing four overlapping time-series datasets based on records from 1961 - 2000.

This series of four animations shows how some of the key indicators of climate change (average global temperature, sea level, sea ice extent, carbon emissions) have changed in Earth's recent history.
