The greenhouse effect is the rapid warming of the Earth due to the trapping of heat in the
atmosphere. Greenhouse gases are able to allow light energy to enter the atmosphere, but

The greenhouse gases are carbon dioxide, methane (both of which are produced in large
quantities by human related activities), water vapor, and chlorofluorocarbons . These are
constantly insulting the atmosphere.
The greenhouse effect is something that is needed for life to exist on Earth. The problem
lies with the intensification brought on by humans. The main contribution to greenhouse
gases that we make is from energy consumption.
There are many things that can occur with global warming. There will be a decline in
biological productivity, the melting of the Arctic, and major disruptions to all
ecosystems. Many more are listed in the chapter.
