In this activity, students work in groups, plotting carbon dioxide concentrations over time on overheads and estimating the rate of change over five years. Stacked together, the overheads for the whole class show an increase on carbon dioxide over five years and annual variation driven by photosynthesis. This exercise enables students to practice basic quantitative skills and understand how important sampling intervals can be when studying changes over time. A goal is to see how small sample size may give incomplete picture of data.

Students use Google Earth to analyze oil consumption per capita in the US and around the world. Students then use spreadsheets to create graphs and calculate statistics regarding per capita energy use among various categories.

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.

This video provides an excellent summary of the role of the oceans and ocean life and makes the point that despite the important role of life in the oceans, there is still much to be learned about the details of the oceanic biota.

This animated visualization of precession, eccentricity, and obliquity is simple and straightforward, provides text explanations, and is a good starting place for those new to Milankovitch cycles.

Interactive visualization that provides a basic overview of the Earth's carbon reservoirs and amount of carbon stored in each, CO2 transport among atmosphere, hydrosphere, geosphere, and biosphere, and a graph comparing global temp (deg C) and atmospheric CO2 levels (ppm) over the past 1000 years.

This video segment from the Earth Operators Manual summarizes how fossil fuels are made, provides a comparison of how long it takes to store energy in coal, oil and natural gas, and discusses how fast we're using them.

These graphs show carbon dioxide measurements at the Mauna Loa Observatory, Hawaii. The graphs display recent measurements as well as historical long term measurements. The related website summarizes in graphs the recent monthly CO2, the full CO2 Record, the annual Mean CO2 Growth Rate, and gives links to detailed CO2 data for this location, which is one of the most important CO2 tracking sites in the world.

This video highlights the work of climate scientists in the Amazon who research the relationship between deforestation, construction of new dams, and increased amounts of greenhouse gases being exchanged between the biosphere and the atmosphere.

This visualization is a website with an interactive calculator that allows for estimation of greenhouse gas production from croplands in the United States.
