How does global wormong happen?

Global warming occurs primarily due to the increase of greenhouse gases in the Earth's atmosphere, mainly from human activities such as burning fossil fuels, deforestation, and industrial processes. These gases trap heat from the sun, leading to a rise in global temperatures. Additionally, land-use changes and agricultural practices contribute to the release of carbon dioxide and methane. The cumulative effect of these actions disrupts natural climate systems, resulting in various environmental impacts.
