I also want to research global warming what it is and its effects on the earth. Ive found that global warming is the tempurture increase around the world. And natural disaters becoming mor frequent. my research shows that global warming is not natural it is caused by man. I have found that the sun is the earths major source of enery. The sun heat is so hot the we can feel it 150mollion kilometers away. Ywo thirds of this heat is absorbed by the water and land . Some of the heat goes back to space and some is stored in the atmosphere. This is called the greenhouse effect. This layer of the atomosoher traps in heat. this is the simplest way to explain global warming in just one paragraph.
