We know what Earth's past climate was like by studying things that have been around for a long time. For example, scientists can study what Earth's climate was like hundreds of years ago by studying the insides of trees that have been alive since then.. But if scientists want to know what Earth's climate was like hundreds of thousands to millions of years ago, they study sediment cores and ice ...

Climate change describes a change in the average conditions — such as temperature and rainfall — in a region over a long period of time. For example, 20,000 years ago, much of the United States was covered in glaciers. In the United States today, we have a warmer climate and fewer glaciers.

Hundreds of plant and animal species have already experienced changes because of climate change. The American pika, for example, is a small mammal that lives in cool mountainous areas in western North America—in fact, it can die when exposed to temperatures warmer than 78˚F.So as the mountain climate heats up, the pika climbs the slopes in search of cooler habitat.

Climate change, therefore, is a change in the typical or average weather of a region or city. This could be a change in a region's average annual rainfall, for example. Or it could be a change in a city's average temperature for a given month or season. Climate change is also a change in Earth's overall climate.
