This NOAA visualization on YouTube shows the seasonal variations in sea surface temperatures and ice cover from 1985 to 2007. The visualization is based on data collected by NOAA polar-orbiting satellites. El NiÃo and La NiÃa are easily identified, as are the trends in decreasing polar sea ice.

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 is a short NASA video on the water cycle. The video shows the importance of the water cycle to nearly every natural process on Earth and illustrates how tightly coupled the water cycle is to climate.

This short animation compares graphs of the natural variation in the sun's energy striking the upper atmosphere vs global surface temperature over a 30-year period to make the point that natural variations do not account for the rising trend line in surface temperatures.

This is an animation from the US Environmental Protection Agency's Students Guide to Global Climate Change, one of a series of web pages and videos about the basics of the greenhouse effect.

This animation depicts real-time wind speed and direction at selected heights above Earth's surface, ocean surface currents, and ocean surface temperatures and anomalies.

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.

An interactive that illustrates the relationships between the axial tilt of the Earth, latitude, and temperature. Several data sets (including temperature, Sun-Earth distance, daylight hours) can be generated.

This qualitative graphic illustrates the various factors that affect the amount of solar radiation hitting or being absorbed by Earth's surface such as aerosols, clouds, and albedo.

An interactive simulation of Earth's seasonal dynamics that includes the axial tilt and other aspects of Earth's annual cycle.

This is part of a larger lab from the University of Nebraska at Lincoln:
