In this activity students learn how Earth's energy balance is regulating climate. This activity is lesson 4 in the nine-lesson module Visualizing and Understanding the Science of Climate Change.

In this activity, learners observe the effects of the layering of warm and cold water and water that is more or less saline than regular water. They will discover how the effects of salinity and temperature are the root cause of thermohaline layering in the ocean.

This interactive displays how climate variables are changing over time (temperature, CO2, Arctic sea ice, solar flux, etc.) in graphical form. Students can examine data over the last 20 years or archived data.

Students explore how various energy sources can be used to cause a turbine to rotate and then generate electricity with a magnet.

As a segment in PBS's Coping with Climate Change series, Hari Sreenivasan reports on the actions the city of Chicago is taking to mitigate climate change in an urban landscape.

This video provides an overview of how computer models work. It explains the process of data assimilation, which is necessary to ensure that models are tied to reality. The video includes a discussion of weather models using the Goddard Earth Observing System (GEOS-5) model and climate models using the MERRA (Modern Era Retrospective Analysis for Research and Applications) technique.

In this activity, students research the relationship between hosts, parasites, and vectors for common vector-borne diseases (VBDs) and evaluate how climate change could affect the spread of disease.

This video highlights research conducted at Woods Hole on how heat absorbed by the ocean and changes of ocean chemistry from human activities could lead to a tipping point for marine life and ecosystems. Includes ice bath experiment that models the tipping point of Arctic sea ice.

This video profiles the Arctic Inuit community of Sachs Harbour and its collaboration with scientists studying climate change. Changes in the land, sea, and animals are readily apparent to the residents of Sachs Harbourâmany of whom hunt, trap, and fishâbecause of their long-standing and intimate connection with their ecosystem. Scientists from a climate change study project interview the residents and record their observations. The scientists can use these firsthand accounts along with their own collected data to deepen their understanding of climate change in the polar region.

This animation demonstrates the changing declination of the sun with a time-lapse animation. It shows how the shadow of a building changes over the course of a year as the declination of the sun changes.
