Scientists measure how plants change the amounts of gases in the air. Changes in amount of greenhouse gases can change the amount of greenhouse effect and global warming.

Living Things Affect Climate
There are many different ways that the plants, animals, and other living things affect climate. Some produce greenhouses gases that trap heat and aid global warming through the greenhouse effect. Others take greenhouse gases out of the air. Here are some examples:
- Plants take greenhouse gases out of the air. During the night, plants release some back into the air. They take much more greenhouse gas out of the atmosphere than they put in.
- Farm animals like cows and sheep make greenhouse gases when they digest their food.
- Wetlands and rice patties and the tiny, microscopic bacteria that live there make greenhouse gas.
- Factories and power plants release greenhouse gas into the atmosphere when fossil fuels are burned.
- Cars and trucks release greenhouse gas when they burn fossil fuels.
- We use fertilizers to help plants grow but they also make greenhouse gas when they break apart in the soil.
- Wildfires put greenhouse gas into the atmosphere as they burn. But if the forest grows back, it will take greenhouse gas out of the atmosphere.
Humans control many things that produce greenhouse gases. Today, more greenhouse
gases are put into the atmosphere than are taken out. This is causing out planet
to become warmer because of the greenhouse
effect.
