An applet about the Milankovitch cycle that relates temperature over the last 400,000 years to changes in the eccentricity, precession, and orbital tilt of Earth's orbit.

This video, along with a background essay, focuses on impacts of climate change on the lives of Native Alaskans around Barrow, Alaska. Specific changes include the timing of the changes in the formation and breakout of sea ice and the impacts on subsistence living.

In this video a scientist explains how DNA extracted from ancient tree remains provides insights about how trees/plants have adapted, over time, to changes in CO2 in the atmosphere. Her lab research investigates changes in plant genotypes under experimental conditions that simulate potential changes in CO2 levels in the future.

This short video shows an example of melting alpine glaciers in the Austrian Alps (Goldberg Glacier). Disappearing alpine glaciers have social and environmental impacts, including the decline of fresh water supplies and contributing to sea level rise.

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

This video highlights a team of scientists who work on reconstructing the mass extinction that occurred 250 million years ago, the end of the Permian Period, and wiped out the majority of life on our planet, resetting the evolution of life. Clues suggest that deadly bacteria might have set off a chemical chain reaction that poisoned the Permian seas and atmosphere.

This video provides an overview of the Center for Transportation Technologies and Systems and its research on alternative fuel vehicles and why they have less impact than current fossil fuel-burning cars on the environment.

This is a National Geographic short video that briefly describes how succulent plants in the South African Karoo biome are dying off due to changes in climate.

This straightforward calculator provides conversions from one unit of energy to the equivalent amount of CO2 emission expected from using that amount.

This video discusses the social and economic impacts (worldwide and in the US) of sea level rise caused by global warming (aired April 1, 2011).
