Global warming is the increase in the average temperature of the Earth's surface due to the effect of greenhouse gases, such as carbon dioxide emissions resulting from the combustion of fossil fuels or deforestation , which trap that heat that would otherwise escape from the Earth. With more heat trapped on Earth, the planet will become hotter, meaning the weather across Earth will change. For example, summers will become hotter and so will winters. It might seem like a good idea, but the conditions we live in are perfect for life, and a sharp increase in temperature could be terrible for us and every other living thing on Earth. The atmosphere contains numerous gases, often in small quantities, that trap heat emitted by the Earth. To ensure that Earth's temperature remains constant, the balance of these gases in the atmosphere must not be upset. Climate change is any substantial change in the Earth's climate that lasts for a prolonged period. Global warming refers to climate change causing an increase in the average temperature of the lower atmosphere. According to the EPA, global warming can have many differences...
