Test your memory while you learn about the chemistry of Earth's atmosphere! 

Explore how everyday choices add up to make your carbon footprint, and what the effect would be on the climate if everybody acted the same way as you in the future.

This simple interactive shows how Earth's temperature rises as the amount of carbon dioxide in the atmosphere increases.

Sort photos of clouds by altitude, by composition, and into groups based on whether they are smooth or turbulent.

Test your memory while you learn about clouds! Click on tiles to reveal photos of clouds - and try to find a matching pair.

Compare possible future carbon dioxide emissions and average global temperatures during the coming century as provided by the Intergovernmental Panel on Climate Change (IPCC).

Compare maps side-by-side of sea ice extent in the Antarctic over several decades.

Compare maps side-by-side of sea ice extent in the Arctic over several decades.

Compare maps of future regional climate projections to assess projected changes in temperature and precipitation.

Compare images of the Sun side-by-side with this interactive viewer. What features can you see in ultraviolet or infrared images?

Compare photos of different solar eclipses side-by-side.

Explore the factors that combine to create a snowstorm in this interactive.

See how Earth's temperature would change if the Sun's brightness increased or dimmed or if Earth's albedo was different.

Help the Joules family make choices that keep their greenhouse gas emissions low.

Can you predict the path of a hurricane? Learn how hurricanes move across an ocean and see if you can determine which cities will be impacted by a hurricane.

Congratulations! You have a new job as a Global Energy Advisor and the people of the planet need your help. You must choose a new mix of energy sources to limit emissions while generating enough energy and keeping costs low.

Sort these molecules as greenhouse gases, borderline cases or not greenhouse gases.

Make a hurricane and learn how sea surface temperature, moisture and wind conditions determine how strong the storm will be.

Make a thunderstorm! Choose the right mix of temperatures and humidity to create a big thunderstorm.

How well can you identify cloud types? Try this game and test your skill!

Explore relationships between pressure and fluid flow in this virtual lab.

In this collection of games, young learners can make a raindrop, steer a hurricane, help a dog keep cool, dress a yeti for the weather, and help a community fight climate change.

Test your memory while you learn about eclipses of the Sun. Click on tiles to reveal pictures of solar eclipses and maps of the path of the November 2012 eclipse in Australia. Try to find matching pairs of pictures.

Sort pictures of El Niño and La Niña conditions based on sea-surface temperatures.

Test your memory while you learn about the Sun, space weather, and Earth's magnetosphere and upper atmosphere.

Sort pictures of the Sun and its features by temperature or by time in the sunspot cycle.

Use this model to explore the relationships between carbon dioxide in Earth's atmosphere and our planet's average global temperature. Try out some "what if" scenarios to see how much our climate may warm during the coming century.

Match tree ring patterns to decode climate clues from the past.
