Climate is like the weather that happens all the time in a specific area over a long period of time. It can be really hot or really cold in some places or it can rain a lot or not at all. Climate is affected by lots of things like how much sunlight an area gets, the amount of rain or snow that falls, and how much wind blows.
Sometimes, people do things that can change the climate like cutting down too many trees or using too much gasoline in cars. This can make the climate change and become warmer or colder than it should be. It's really important to take care of the earth so that we can keep the climate just right for all the plants, animals and people that live here.
