Global Warming
The earth's climate is driven by a continuous flow of energy from the sun. Heat energy from the sun passes through the earth's atmosphere and warm the earth's surface. As the temprature increases, the earth sends heat energy (infrared radiation) back into the atmosphere. Some of this heat is absorbed by gases in the atmosphere, such as corban dioxide, water vapour, methane, nitrous oxide and halocarbons. Because of this action the earth's temprature is good for life but the percentage of these gases are increasing and the earth's temprature is also increasing. Which is very dangerous for our life. Today we are seeing the impact of climate change around the world. Melting glaciers, rising sea levels stronger storms, higher floods, less snow north and more drought south. Now the time has come to control global warming.People must aware of this. There is some ideas to control global warming. 1.plant more trees. 2.don't waste water. 3. don't use and burn plastics. 4. stop misusing the resources. 5.population should be in control. 6.Use solar energy.
