In this video, Michael Mann and Stefan Rahmstorf explore some of the information from the 2013 IPCC 5th report in light of public perceptions of climate science.

Students conduct a greenhouse gas emission inventory for their college or university as a required part of the American College and University Presidents Climate Commitment.

This is a video overview of the history of climate science, with the goal of debunking the idea that in the 1970s, climate scientists were predicting global cooling.

In this activity, students use climate data to develop a simple graph of how climate has changed over time and then present the result in a blog, emphasizing effective science communication.

This video highlights the Pentagon's focus on climate change as the military examines potential risks, strategic responses, and impacts of climate change on future military and humanitarian missions. In 2010, for the first time, the Pentagon focused on climate change as a significant factor in its Quadrennial Defense Review of potential risks and strategic responses. Rear Admiral David Titley, Oceanographer of the Navy, explains why the US military sees clear evidence of climate change and how those changes will affect future military and humanitarian missions.

This is a multi-step activity that helps students measure, investigate, and understand the increase in atmospheric CO2 and the utility of carbon offsets. It also enables students to understand that carbon offsets, through reforestation, are not sufficient to balance increases in atmospheric C02 concentration.

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 static graph of changes in CO2 concentrations goes back 400,000 years, showing the dramatic spike in recent years.

The Climate Momentum Simulation allows users to quickly compare the resulting sea level rise, temperature change, atmospheric CO2, and global CO2 emissions from six different policy options projected out to 2100.

This visualization provides an informative summary of the quarterly seasonal global weather and climate using the 3-D Science on a Sphere format. These video summaries use animations of recent NOAA data and an engaging commentary to review the climate highlights of the past 4 seasons. Topics include, El Nino/La Nina, temperature trends, extreme weather, and emerging climate research.
