Click to Play! A Guide to Climate Change for Kids. What's in the Atmosphere? What Is Climate Change? What Is the Greenhouse Effect? Weather or Climate?
The water cycle is the path that all water follows as it moves around Earth in different states. Liquid water is found in oceans, rivers, lakes—and even underground. Solid ice is found in glaciers, snow, and at the North and South Poles. Water vapor—a gas—is found in Earth’s atmosphere.
Mystery. Big Questions. What does global climate change mean? What is the big deal with carbon? What is the greenhouse effect? How do we know the climate is changing?
The Short Answer: Climate change describes a change in the average conditions — such as temperature and rainfall — in a region over a long period of time. NASA scientists have observed Earth’s surface is warming, and many of the warmest years on record have happened in the past 20 years.
Have you heard your parents or people in videos talking about climate change? Ever wondered what it is and why we care about it so much? NASA scientists have been studying Earth’s climate for more than 40 years. We used what we’ve learned in that time to answer some of your biggest questions below!
NASA has observed increases in the amount of carbon dioxide and some other greenhouse gases in our atmosphere. Too much of these greenhouse gases can cause Earth's atmosphere to trap more and more heat.

The Brief Overview. Weather is a specific event—like a rainstorm or hot day—that happens over a few hours, days or weeks. Climate is the average weather conditions in a place over 30 years or more. NASA has observed that Earth's climate is getting warmer.
