Special Guest Posting: “Climate Change” by Jordi de la Torre (3rd Grade)

Greenhouse gases cause global warming. Greenhouse gases are gases that trap the sun's heat. One greenhouse gas is carbon dioxide. Some carbon dioxide is good because plants use it to make food. But people are adding much more. The result is that the extra carbon dioxide traps heat causing the temperature of the Earth to rise. If the temperatures keep rising it could cause extreme weather, warmer seas, changing habitats and hurt people and animals.
