In this activity students work with data to analyze local and global temperature anomaly data to look for warming trends. The activity focuses on the Great Lakes area.
Paul Andersen explains how the climate on the earth is affected by …
Paul Andersen explains how the climate on the earth is affected by the amount of solar radiation and the greenhouse affect. The addition of anthropogenic greenhouse gases has led to global warming which is impacting humans on the planet. A discussion of the greenhouse effect and greenhouse gases (including water vapor, carbon dioxide, methane, nitrous oxide, and CFCs) is included. Countries have committed to reduce through both the Kyoto Protocol and the Paris Agreement.
Students learn how the greenhouse effect is related to global warming and …
Students learn how the greenhouse effect is related to global warming and how global warming impacts our planet, including global climate change. Extreme weather events, rising sea levels, and how we react to these changes are the main points of focus of this lesson.
How might Earth's temperature change in the future? Use this model to …
How might Earth's temperature change in the future? Use this model to explore how changing human emissions of greenhouse gases might affect the temperature. The model incorporates positive and negative feedback loops. Ice cover and cloud cover change in response to the level of water vapor and temperature in the model.

The activity follows a progression that examines the CO2 content of various gases, explores the changes in the atmospheric levels of CO2 from 1958 to 2000 from the Mauna Loa Keeling curve, and the relationship between CO2 and temperature over the past 160,000 years. This provides a foundation for examining individuals' input of CO2 to the atmosphere and how to reduce it.
In this activity, students will practice the steps involved in a scientific …
In this activity, students will practice the steps involved in a scientific investigation as they learn why ice formations on land (and not those on water) will cause a rise in sea level upon melting. This is a discovery lesson on ice and water density and displacement of water.

This is lesson five of a 9-lesson module. Activity explores the effects of climate change on different parts of the Earth system and on human well-being: polar regions, coral reefs, disease vectors, extreme weather, and biodiversity.

This short video reviews how nations and individuals can work together to reduce the emission of CO2. It discusses strategies to reduce greenhouse gas emissions (energy conservation, renewable energies, change in energy use) and the role that government can play in this process.
This video is one of a seven, Climate Change: Lines of Evidence …
This video is one of a seven, Climate Change: Lines of Evidence series, produced by the the National Research Council. It outlines and explains what evidence currently exists in support of humans playing a role in contributing to the rise in atmospheric carbon dioxide levels.
This video features changes in the land, sea, and animals that are …
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.

In this activity, students download historic temperature datasets and then graph and compare with different locations. As an extension, students can download and examine data sets for other sites to compare the variability of changes at different distinct locations, and it is at this stage where learning can be individualized and very meaningful.
This activity uses two interactive simulations to illustrate climate change, 1) at …
This activity uses two interactive simulations to illustrate climate change, 1) at the micro/molecular level - modeling the impact of increasing concentrations of greenhouse gases in the atmosphere on surface temperature and 2) at the macro level - modeling changes in glacier thickness and flow as a result of rising surface temperature.
This short video illustrates how warming ocean temperature is a major factor …
This short video illustrates how warming ocean temperature is a major factor in climate change, particularly the increase in severity of extreme weather (notably storms and drought).
This is a classroom activity about the forcing mechanisms for the most …
This is a classroom activity about the forcing mechanisms for the most recent cold period: the Little Ice Age (1350-1850). Students receive data about tree ring records, solar activity, and volcanic eruptions during this time period. By comparing and contrasting time intervals when tree growth was at a minimum, solar activity was low, and major volcanic eruptions occurred, they draw conclusions about possible natural causes of climate change and identify factors that may indicate climate change.
