Global warming is caused by greenhouse gases such as carbon dioxide and methane released into the atmosphere from human activities like burning fossil fuels and deforestation. If left unaddressed, global warming is expected to raise sea levels and temperatures worldwide, threatening coastal cities, causing more extreme weather, and potentially disrupting ecosystems and causing some plant and animal species to go extinct. Individual actions like recycling, using less energy, and opting for more sustainable transportation can help reduce the impacts of global warming.
