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

This video is the second of three short videos showcasing the dramatic changes in Alaska's marine ecosystems. The video highlights the marine mammals and birds and how they depend on Arctic sea ice, as well as questions about how these animals will cope in the face of climate change.

This video from a 2005 NOVA program features scientists who study the Jakobshavn Isbrae glacier in western Greenland. The glacier is shrinking and moving faster due to increased melting in recent years. The video includes footage of scientists in the field explaining methods and animation of ice sheet dynamics leading to faster glacier movement.

In this activity, students learn about the urban heat island effect by investigating which areas of their schoolyard have higher temperatures - trees, grass, asphalt, and other materials. Based on their results, they hypothesize how concentrations of surfaces that absorb heat might affect the temperature in cities - the urban heat island effect. Then they analyze data about the history of Los Angeles heat waves and look for patterns in the Los Angeles climate data and explore patterns.

This video on phenology of plants and bees discusses the MODIS satellite finding that springtime greening is happening one half-day earlier each year and correlates this to bee pollination field studies.

This activity involves plotting and comparing monthly data on atmospheric C02 concentrations over two years, as recorded in Mauna Loa and the South Pole, and postulating reasons for differences in their seasonal patterns. Longer-term data is then examined for both sites to see if seasonal variations from one site to the other carry over into longer term trends.

This NASA animation of the Five-Year Average Global Temperature Anomalies from 1881 to 2009 shows how temperature anomalies have varied in the last 130 years. The color-coded map displays a long-term progression of changing global surface temperatures from 1881 to 2009. Dark red indicates the greatest warming and dark blue indicates the greatest cooling.

After 90 percent of the town was damaged or destroyed by a tornado, Greensburg, Kansas, and Kiowa County Memorial Hospital developed a Long-Term Community Recovery plan to rebuild for resilience.

Food Sovereignty, Climate Change, and The Three Sisters: Mandaamin (Corn), Mashkodesimin (Bean), Okosimaan (Squash, Pumpkin)Grade Level: 9 -12Content Area: Science, Indigenous knowledgeAuthor: Wendy Fuller, Lac Courte Oreilles Ojibwe School, High School Science TeacherIn an effort to encourage students to learn where their food comes from, make more informed decisions about what they eat and how what they eat impacts the environment, students are introduced to indigenous teachings regarding companion planting of food crops. In this remix of an earlier project, students expand their understanding of food sovereignty and the impact of climate change on the beings, The Three Sisters.

In this activity, students explore past examples of climate variability in three locations: the Peruvian and Bolivian Andes, Central America, and coastal Greenland, and consider differences between climate variability and climate change.

Trees within a city can help reduce urban heat, control stormwater, and provide habitat to local wildlife. As climate conditions change, a Chicago group is working to enhance its urban forest so that the city can continue to receive these benefits.

This lesson has students exploring the consequences of burning fossil fuels: air pollution and the greenhouse effect.

This video features the story of a multi-generational, family-run dairy business in Oregon. The family strives for sustainability in their operations by conserving energy and reducing greenhouse gases across many aspects of their business.

In this activity, students investigate what causes the seasons by doing a series of kinesthetic modeling activities and readings.

Urban governance comprises the various forces, institutions, and movements that guide economic and physical development, the distribution of resources, social interactions, and other aspects of daily life in urban areas. This course examines governance from legal, political, social, and economic perspectives. In addition, we will discuss how these structures constrain collective decision making about particular urban issues (immigration, education‰Ű_). Assignments will be nightly readings and a short paper relating an urban issue to the frameworks outlined in the class.

In partnership with the National Science Digital Library and Apple, NCAR and UCAR offer podcasts that provide a brief and accessible overview on climate and climate change. These podcasts, short 5-8 minute videos you can download on your computer or iPod, are a part of the NSDL on iTunes U collection.

In this classroom activity, students analyze regional energy usage data and their own energy bills to gain an understanding of individual consumption, regional uses, costs, and sources of energy.

In this activity, students will use oxygen isotope values of two species of modern coral to reconstruct ambient water temperature over a four-year period. They use Microsoft Excel, or similar application, to create a spreadsheet of temperature values calculated from the isotope values of the corals by means of an algebraic equation. Students then use correlation and regression techniques to determine whether isotope records can be considered to be good proxies for records of past temperatures.

This site provides a useful set of graphical representations of mean temperature change in different land/ocean surfaces over the past 120+ years.

Global Global warming is primarily a problem of too much carbon dioxide (CO2) in the atmosphere which acts as a blanket, trapping the heat and warming the planet.
