What is Global Warming? Global warming , also known as climate change, is the gradual increase in the overall temperature of the Earth's atmosphere, primarily caused by human activities that release greenhouse gases, such as carbon dioxide and methane, into the atmosphere. Causes of Global Warming 1. Burning of Fossil Fuels : The burning of coal, oil, and gas for energy releases large amounts of carbon dioxide into the atmosphere. 2. Deforestation : The clearance of forests for agriculture, urbanization, and other purposes releases carbon dioxide and reduces the ability of forests to act as carbon sinks. 3. Agriculture : The production of meat, especially beef, and other animal products leads to the release of methane and nitrous oxide. 4. Industrial Processes : The production of cement, steel, and other industrial processes release large amounts of greenhouse gases. Effects of Global Warming 1. Rising Sea Levels : The melting of glaciers and ice sheets, and the expansi...
