In this short video, host Dr. Ryan interviews graduate student Amy Steiker at the Institute of Arctic and Alpine Research about her research, using isotopes of nitrous oxide, connecting human activity to greenhouse gas emissions.

This video provides an overview of changes happening in the Arctic.

This video introduces phytoplankton - the base of the marine food web, the source of half of the oxygen on Earth, and an important remover of CO2 from the atmosphere. The video also explains how satellites are used to monitor phytoplankton and how warming waters and acidification negatively affect phytoplankton.

In this activity, students use Google Earth and information from several websites to investigate some of the consequences of climate change in polar regions, including the shrinking of the ice cap at the North Pole, disintegration of ice shelves, melting of Greenland, opening of shipping routes, effects on polar bears, and possible secondary effects on climate in other regions due to changes in ocean currents. Students learn to use satellite and aerial imagery, maps, graphs, and statistics to interpret trends accompanying changes in the Earth system.

In this activity, students collect weather data over several days or weeks, graph temperature data, and compare the temperature data collected with long-term climate averages from where they live. Understanding the difference between weather and climate and interpreting local weather data are important first steps to understanding larger-scale global climate changes.

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.

This hands-on activity introduces students to the process of fermenting different carbohydrate sources into ethanol. Teachers demonstrate yeasts' inability to metabolize certain food sources.

This activity engages students in a role play to negotiate an agreement between the United States and China about climate change policies. Students use given background material or can do their own additional research to present their assigned stakeholder's position in a simulated negotiation.

This interactive map allows students to experiment with decadal average temperature projections. Overall temperatures are expected to rise throughout the century and this tool demonstrates those projected measurements.
