In this video, several scientists identify and describe examples of increasing health problems that they believe are related to climate change.

A set of eight photographs compiled into a series of slides explain how urban areas are facing challenges in keeping both their infrastructure and their residents cool as global temperatures rise. Chicago is tackling that problem with a green design makeover. This report is part of PBS's Coping with Climate Change series and could challenge students to consider engineering designs to help their own cities be greener.

This article and slide show from the New York Times, features several scientists from the University of Alaska, Fairbanks, who study the effects of thawing permafrost in Alaska.

This video describes how Colorado has planned for and uses clean energy resources to reduce its carbon footprint.

This animated visualization represents a time history of atmospheric carbon dioxide in parts per million (ppm) from 1979 to 2011, and then back in time to 800,000 years before the present.

In this activity, students learn about sea ice extent in both polar regions (Arctic and Antarctic). They start out by forming a hypothesis on the variability of sea ice, testing the hypothesis by graphing real data from a recent 3-year period to learn about seasonal variations and over a 25-year period to learn about longer-term trends, and finish with a discussion of their results and predictions.

This introductory video summarizes the process of generating solar electricity from photovoltaic and concentrating (thermal) solar power technologies.

This hands-on activity explores the driving forces behind global thermohaline circulation.

This video provides an overview of the research of the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) on converting biomass to liquid fuels.

This visualization shows in five steps how ice cores provide a measure of the temperature in the past.
