The rise of air temperatures near Earth's surface over the past century is known as global warming. Earth has experienced periods of gradual wanning and cooling throughout its existence due to natural causes, such as volcanic eruptions and variations in the un 's output. However, scientists have attributed the current increase in global temperatures to human causes-primarily the release of certain gases into the atmosphere as a result of industrial activity. The e gases collecrively termed greenhouse gases-absorb and trap heat emitted from Earth's surface through a phenomenon known as the greenhouse effect.In addition to the rise in near- urface air temperatures, global warming encompasses other climatic changes caused by this warming, such as variations in precipitation patterns, winds, and ocean currents. For this reason, the terms global warming and climate change are sometimes used interchangeably.
