Answer as written by the student:
Good evening, respected principal, teachers, and my dear friends. Today, I am going to talk about global warming, its causes, and how to mitigate it.
Global warming is the phenomenon of rising average air temperatures near Earth’s surface over the past 100 to 200 years. It is caused by human activities that increase the concentration of greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, in the atmosphere. These gases trap the sun’s heat and prevent it from escaping into space, creating a greenhouse effect.
