This is an interactive graph that involves records of ice cover in two Wisconsin lakes - Lake Mendota and Lake Monona - from 1855-2010.

Animations of CO2 concentration in the free troposphere, as simulated by NOAA's ESRL CarbonTracker.

This video clip highlights the effort on by a group of young students to ban the use of plastic shopping bag in the city of Santa Monica. The video documents the effort and provides visual testimony of the effects that trash and specifically plastic bags have on the ocean ecosystem.

In this video, students explore the work of Jay Keasling, a synthetic biologist experimenting with ways to produce a cleaner-burning fuel from biological matter, using genetically modified microorganisms.

In this video, a PhD Student from the University of Maine explains how ice cores are used to study global climate change.

This video on phenology of plants and bees discusses the MODIS satellite finding that springtime greening is happening one half-day earlier each year and correlates this to bee pollination field studies.

This short video discusses where carbon dioxide, the gas that is mainly responsible for warming up our planet and changing the climate, comes from. It discusses how the rise in atmospheric carbon dioxide comes directly from the burning of fossil fuels and indirectly from the human need for energy.

This is an animated interactive simulation that illustrates differential solar heating on a surface in full sunlight versus in the shade.

These animations depict the three major Milankovitch Cycles that impact global climate, visually demonstrating the definitions of eccentricity, obliquity, and precession, and their ranges of variation and timing on Earth.

This video from the U.S. National Academies summarizes the energy challenges the United States faces, the technological challenges, and the need for behavior and policy changes required to meet the challenge.
