Global warming is caused by the increasing concentration of greenhouse gases, such as carbon dioxide, in the Earth's atmosphere.

Global warming is caused by the increasing concentration of greenhouse gases such as carbon dioxide in the atmosphere. When sunlight enters the Earth's atmosphere, some of it is reflected back into space, while some of it is absorbed by the Earth's surface and re-emitted as heat. Greenhouse gases, like carbon dioxide, trap some of this heat in the atmosphere, leading to an overall increase in the Earth's surface temperature. This phenomenon is known as the greenhouse effect, and it is the primary cause of global warming.
