What is Global Warming?


What is Global Warming? Global Warming is a climate change within the Earth’s Atmosphere. In Scientific Terms Global Warming is the increase in average temperature of the Earth’s atmosphere and oceans. The earth is naturally warmed by the sun’s rays or radiation from the Sun which passes through the earth's atmosphere and is reflected back out to space again. The Atmosphere is made up of layers which are made of gases or greenhouse gases. These Greenhouse gases maintaining the earth at a right temperature so that animals, plants, and humans can survive. But with all the greenhouse gases that have been accumulating produced by mankind it prevents the sun’s rays from leaving the Earth thus warming the Earth. Greenhouse gases are like thermal blankets that cover the earth in order to maintain a stable environment. So some global warming is good. But if extra greenhouse gases are made, the thermal blanket gets thicker and too much heat is kept in the earth's atmosphere. That's when global warming's bad. There are ways to prevent Global Warming from getting any worse. But the next blog will be about how Global Warming can affect civilization. What are the effects of Global Warming? How are we as in humans contributing to Global warming and the increase in greenhouse gases?
