I think I might know a bit, but I can tell you what I do know.
Once upon a time, there was a girl called Chloe.One day, she was at her school called Southbound elementary school, when her teacher asked her whether she knew what Climate change was.
Chloe knows a little bit about climate change, and she is going to tell you
The heat ray sfrom the sun enter the atmosphere of the earth
Well done Chloe!!!
Thousands of years ago, the atmosphere was quite thin. However, because we are producing so much pollution, it has got thicker. This is because the carbon dioxide and the other chemicals are being released into the air which is making it thicker.
So, when the heat rays enter the atmosphere, they are trapped into the surrounding air, eventually heating up the whole earth.
