Introduction: Greenhouse Effect The normal temperature of the Earth's surface is slowly rising because of things people do, mostly putting greenhouse gases like carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O) into the air. The earth gets warmer because these gases trap heat from the sun. This is called the "greenhouse effect." Why the Earth is warming up: 1. Burning fossil fuels: When coal, oil, and natural gas are burned for energy, a lot of CO₂ is released into the air. 2. Destruction of forests: Cutting down trees lowers Earth's ability to take CO₂ from the air. 3. Agriculture and Livestock: Methane is released by livestock, especially cows, and nitrous oxide is released by fertilizers. Both are very strong greenhouse gases. 4. Activities in the industrial sector: Many greenhouse gases and pollution are released into the air by factories. What global warming does: 1. Rising temperatures : The average temperature around the world is going up, which...
