These changes may be natural, but since the 19th century, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels, such as coal, oil and gas, which produce gases that trap calories. . Causes and consequences of climate change. Climate change is one of the greatest challenges facing the planet. Human activity is its main origin and its effects can be devastating. The Earth's atmosphere is made up of different gases whose function is to maintain an appropriate temperature for life. This natural phenomenon is called the greenhouse effect. It is necessary that there is a balance in the emission of greenhouse gases to maintain its fair proportion. However, human activities have increased the production of these gases causing the so-called global warming, the main cause of climate change, and little by little it will get out ...
