In this activity, students explore how, in New England, the timing of color change and leaf drop of deciduous trees is changing.

This narrated slide presentation shows the carbon cycle, looking at various parts of this biogeochemical sequence by examining carbon reservoirs and how carbon is exchanged among them and the atmosphere.

This video, from ClimateCentral, features a team of scientists from the Northern Greenland Eemian Ice Drilling Project (NEEM), who study atmospheric air bubbles trapped in an ice core from a period in Greenland's ice sheet which began about 130,000 years ago and lasted about 10,000 years; a period known as the Eemian. The air bubbles from the ancient atmosphere - all aligned on the same time scale - reveal what happened with climate change over that period of time.

In this activity, students construct a Global Warming Wheel Card, a hand-held tool that they can use to estimate their household's emissions of carbon dioxide and learn how they can reduce them. One side of the wheel illustrates how much carbon dioxide a household contributes to the atmosphere per year through activities such as driving a car, using energy in the home, and disposing of waste. The other side shows how changes in behavior can reduce personal emissions.

This video is essentially an infomercial about electric cars - components, challenges, benefits - narrated by Antonio Neves of the.News and featuring various members of the auto industry.

This video shows some of the most dramatic fluctuations to our cryosphere in recent years, using visuals created with a variety of satellite-based data.

This is a series of 10 short videos, hosted by National Science Foundation, each featuring scientists, research, and green technologies. The overall goal of this series is to encourage people to ask questions and look beyond fossil fuels for innovative solutions to our ever-growing energy needs.

As a segment in PBS's Coping with Climate Change series, Hari Sreenivasan reports on the actions the city of Chicago is taking to mitigate climate change in an urban landscape.

This lesson is comprised of three activities (three class periods). Students use web-based animations to explore the impacts of ice melt and changes to sea level. Students are introduced to topographic maps by doing a hands-on activity to model the contours of an island. Students examine the relationship between topography and sea level change by mapping changing shorelines using a topographic map.

This is the first of three short videos showcasing the dramatic changes in Alaska's marine ecosystems through interviews with scientists and Alaska Natives. This introduction to the impacts of climate change in Alaska includes interviews with Alaska Natives, commentary by scientists, and footage from Alaska's Arctic.
