Global warming is one of the most serious challenges facing our planet today. It occurs due to the increase of greenhouse gases in the atmosphere, such as carbon dioxide and methane. These gases trap heat, causing the Earth's temperature to rise. This leads to severe consequences, including melting ice caps, rising sea levels, and extreme weather events. To combat global warming, people can reduce fossil fuel consumption, use renewable energy sources, and plant more trees. Everyone has a role to play in protecting the environment and ensuring a sustainable future.
