What is global warming?

 Global warming is the increase of near-surface air and ocean temperatures. Greenhouse gases exist to keep the planet warm by trapping heat within it. Usually, when heat enters the atmosphere, it comes in short radiation waves. The greenhouse gases trap the heat, which causes a warming effect on Earth.
