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.

In this activity, students learn about sea ice extent in both polar regions (Arctic and Antarctic). They start out by forming a hypothesis on the variability of sea ice, testing the hypothesis by graphing real data from a recent 3-year period to learn about seasonal variations and over a 25-year period to learn about longer-term trends, and finish with a discussion of their results and predictions.

This is a debate-style learning activity in which student teams learn about energy sources and are then assigned to represent the different energy sources. Working cooperatively, students develop arguments on the pros and cons of their source over the others.

Runoff in urban areas is an increasingly important issue when it comes to water quality. It is a major hydrologic issue in New York City, as urban infrastructure creates excess runoff and impervious surfaces decrease the infiltration rate of land surfaces. This excess runoff, which often times carries with it pollutants and contaminants, has proven to create water quality issues. It has become ever more critical to try to mitigate the influx of runoff into our waterways. Urbanization increases runoff, and in NYC 64% of the area is impervious. In this module students will explore green roofs as a potential solution to the environmental impacts of increased precipitation brought on by climate change. They will evaluate data collected from studies on 15 green roofs from different areas of the US and other countries, as well as historical precipitation data from Central Park in NY to illustrate how precipitation patterns are changing and if we need to use green infrastructure, such as green roofs, to combat the symptoms of climate change. Students will also use Model My Watershed , a watershed-modeling web app, to analyze real land use data, model storm-water runoff and water-quality impacts using professional-grade models, and compare how different conservation or development scenarios could modify runoff and water quality.

This is a series of 10 short videos, hosted by the 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.

In this short video, atmospheric scientist Scott Denning gives a candid and entertaining explanation of how greenhouse gases in Earth's atmosphere warm our planet.
In this activity, students, working in small groups, respond to a series …
In this activity, students, working in small groups, respond to a series of questions asking them to analyze a diagram of the long-term, global average energy budgets for the atmosphere and the earth's surface (below). They then are asked to explain how the greenhouse effect works in terms of several basic physical principles applied to their analysis. Finally, they are asked to apply the same principles to the predict changes in global average atmospheric and surface temperatures as a result of adding greenhouse gases to the atmosphere.
In this role-play activity, students take the roles of various important players …
In this role-play activity, students take the roles of various important players in the climate change policy negotiation including politicians, scientists, environmentalists, and industry representatives. Working in these roles, students must take a position, debate with others, and then vote on legislation designed to reduce greenhouse gas emissions in the United States. Can be used in a variety of courses including writing and rhetoric, and social sciences.

This is an interactive table with a comprehensive list of 29 greenhouse gases, their molecular structures, a chart showing a time series of their atmospheric concentrations (at several sampling sites), their global warming potential (GWP) and their atmospheric lifetimes. References are given to the data sets that range from the mid-1990s to 2008.

This lesson covers different aspects of the major greenhouse gases - water vapor, carbon dioxide, methane, nitrous oxides and CFCs - including some of the ways in which human activities are affecting the atmospheric concentrations of these key greenhouse gases. This is lesson six in a nine-lesson module about climate change.

This animation allows students to explore the infrared spectra of greenhouse gases and depict the absorption spectra. Vibrational modes and Earth's energy spectrum can also be overlaid.

Students work in pairs to survey seafood items sold in local grocery stores or fish markets, recording whether items are farm-raised or wild caught, fresh, frozen or preserved, as well as country of origin. Students use the Seafood Watch website to research the status of each seafood item (e.g., best choice, good choice or avoid). Class data is compiled in an online or Excel spreadsheet. Students use class data to create bar graphs and pie charts of the data for the different categories. Students turn in individual analyses and answer questions based on class results.

The map shows a 10% probability of ground accelerations reaching or exceeding a certain % of gravity within the next 50 years. Students then adjust the acceleration value for the soil conditions/geologic materials that their home sits on. Once the acceleration hazard is determined, students equate that hazard to the Mercalli Intensity Scale and investigate the potential damage expected at their homes. Students also take into consideration housing types and the weaknesses inherent in different types/ages of structures.

In this role-playing activity, learners are presented with a scenario in which they determine whether the Gulf Stream is responsible for keeping northern Europe warm. They must also address the potential future of the Gulf Stream if polar ice were to continue melting. The students work in small groups to identify the issue, discuss the problem, and develop a problem statement. They are then asked what they need to know to solve the problem.
