A video that introduces permafrost and its distribution on Earth. The video also describes the changing nature of permafrost across several regions due to higher surface temperatures and the possible impact of permafrost thawing on Earth’s climate.
A set of hands-on classroom and computer-based activities for students to learn about permafrost and to explore various web-based scientific data portals to investigate permafrost distribution, characteristics of permafrost, and the effects of thawing permafrost on the atmosphere and the environment.
A reading that explains how the analyses of hydrogen and oxygen isotopes from ice cores determine past temperatures on Earth.
A set of classroom/laboratory activities to reconstruct Earth’s past climate using isotopic composition data from ice cores and to highlight the influence of orbital forcing and atmospheric carbon dioxide feedback on Earth’s climate.
A classroom/laboratory activity to learn about the isotopes of hydrogen and oxygen, analyze the isotopic composition of ice, and understand how isotopic compositions can be used to recreate past temperatures and climate.
Students will plot graphs to analyze data from the Vostok ice core in Antarctica, learn about the ice age and the gas age, calculate past temperatures using hydrogen isotope data, and discuss the possible impacts of changes in carbon dioxide (CO2) and methane (CH4) concentrations on climate.
Use this tool to help your students find answers to:
- How can you use hydrogen isotope data in an ice core to determine temperature?
- How can the isotopic composition of air bubbles in ice cores be used to recreate past climate?

A teaching module that demonstrates the use of linear and quadratic regression to analyze Arctic sea ice extent data and the use of graphs, sample correlations, and multiple regression to analyze atmospheric CO2 level data, solar irradiance data, and average global temperature data.
A classroom/laboratory activity that introduces the relationship between climate and the cryosphere, explains how sea-level rise can be predicted (based on average global temperature change), and triggers a discussion on the potential impacts of sea-level rise.
A classroom/laboratory activity to learn about glacial retreat and to predict the complete melting of a glacier (specifically, for an example in Glacier National Park).
An interactive visualization to explore the effects of melting ice sheets and the resulting sea level rise on coastal areas.
An interactive visualization to visualize the shrinking and growing of a glacier as a result of changes in snowfall and temperature.
A reading that introduces the topic of glaciers and their formation.
|This audio podcast discusses how glaciers in the Yukon are responding to climate change. It focuses on changes in the physical characteristics of these glaciers and several methods used by glaciologists to track changes due to climate and weather.|
A classroom/laboratory activity to perform linear regression on climate data from the Arctic.
A mobile app to learn about glaciers across the world.
