This podcast features current research of Harvard scientists monitoring the flow of carbon through the forest, an accompanying essay, and an audio slideshow that focuses on land changes in the region over the past centuries.

This is a graphic that illustrates anomalies in tropospheric temperatures over a 50-year time period and is based on 7 different datasets superimposed on each other. It is one of 9 climate indicators documented in the AMS State of the Climate report.

One of a suite of online climate interactive simulations, this Greenhouse Gas Simulator uses the bathtub model to demonstrate how atmospheric concentrations of CO2 will continue to rise unless they are lowered to match the amount of CO2 that can be removed through natural processes.

This short video, is the fifth in the National Academies Climate Change, Lines of Evidence series. It focuses on greenhouse gases, climate forcing (natural and human-caused), and global energy balance.

This video looks at the impact of changing climate on animal habitats around the world, showing how different creatures are responding to changing temperatures and precipitation patterns.

This activity with a lab report instructs students to solve and plot 160,000 years' worth of ice core data from the Vostok ice core using Excel or similar spreadsheets to analyze data. Students learn about ice cores and what they can tell us about past atmospheric conditions and the past atmospheric concentrations of CO2 and CH4.

A short video on the causes of ocean acidification and its effects on marine ecosystems.

This graphic represents the decline in Arctic sea ice extent from the 1950's to 2010 during the month of September. The image has three graphed and superimposed datasets, demonstrating the overall decline in Arctic sea ice extent over a 60-year time scale.

In this interactive simulation, students adjust mountain snowfall and temperature to see the glacier grow and shrink, and use scientific tools to measure thickness, velocity, and glacial budget.

This activity offers an introduction to working with Geographic Information Systems (GIS) by using field data on the Urban Heat Island Effect that was collected by students. The field data is entered in the GIS, displayed in a map, and analyzed.
