Global warming, or Greenhouse, is defined as the rise in the average atmospheric air temperature found in the lower layer of the Earth’s surface over the past century or two. This phenomenon occurs when the sun's heat is trapped or trapped in the Earth's atmosphere after it enters it, which raises the temperature of the earth and makes it warmer, and this is done by absorbing atmospheric gases such as carbon dioxide for the sun's energy and trapping it near the earth, which contributes to the warming of the earth.
