There are several causes of recent climate change, but individuals all share something in common. Recent warming, like driving vehicles, heating houses, operating plants, and changing forests into cities, is a side effect of many things people do. The responsibility for recent climate change is even on our landfills and farm animals. The climate is moving. The surface temperature of the Planet during the 20th Century increased by 0.6 ° Celsius (1.1 ° F). Although the atmosphere has changed over the evolution of the World, this is the first time that the primary cause is mankind. greenhouses produce gas such as carbon dioxide into the atmosphere by burning fossil fuels such as coal, oil, and gas. In the atmosphere that was on its way out to space, these gases trap heat, allowing the greenhouse effect of Earth to become more intense, warming the world. Changes in the way land are used also change the environment as well. For example, as trees and other trees are taken down to make room for new houses or parking lots, the world warms because, without the vegetation, less carbon dioxide is produced from the atmosphere. Plus, concrete and houses continue to keep on to more heat than trees and grass, so they remain warm for some time until warmed by the sun. While we’re going to see a certain level of global warming due to our actions in the past century, there are also options to help slow down the pace of warming. Currently, the range of future warming over this century is mostly because we are not aware of how the world will be influenced by humans. It will cause less pollution if it adds fewer greenhouse gases to the atmosphere. With people, the actions of people as well as the sun and volcanoes influence the atmosphere. Once the systems produced human activity that produced a rise in the volume of greenhouse gases in the atmosphere, what happened to Earth’s temperature over the past century was fairly correctly expected. Without people, the atmosphere is primarily influenced by sunshine fluctuations and volcanic eruptions. In those scenarios, the simulations find that during the past century, the Planet would have cooled somewhat, which does not match what really occurred.
