Climate change is the significant change of  weather over time. This is very important. The reason that this is very important is because it ties in with many other things. One thing that it ties in with is green housing.Green housing is the  warming of the earth caused when heat from the sun is trapped by carbon dioxide and methane  in the atmosphere . Methane is a gas in the atmosphere that contributes to the greenhouse effect. It is given when an animal uses  the bathroom or burps. Carbon dioxide is a greenhouse gas that is given off when fossil fuels are burned. I am going to talk about a couple more then i am going to stop because there is a lot. A fossil fuel is a fuel such as oil and coal that has been created by the remains of living organisms that died long ago. That is mostly what climate change is.
