Climate Detectives
Scientists have to think like detectives. They look for clues to help them understand how the world works. Then they investigate the clues to find evidence – real facts that can give them a better idea of what is going on. Here are some of the ways that scientists gather evidence about climate, both past and present.
Weather Stations
Weather stations help us find out the temperature on the surface of the Earth. Weather stations use special thermometers that tell us the temperature. They can be set up almost anywhere on land.
Weather Balloons
Weather balloons are released to float high up into the atmosphere. They carry special instruments that send all kinds of information about the weather back to people on the ground.
Ocean Buoys
A buoy is an object that floats on water, and is often used to warn boats away from dangerous places in the ocean or on a river. But some buoys have special instruments on them. These buoys can tell us the temperature and other information.
Weather Satellites
Scientists send satellites into space to travel around the Earth. The satellites send back information to scientists on the ground. Some of the information they give us is about the weather and the Earth’s temperature.
