The document discusses global warming, describing it as the increase in temperature around the world caused by pollution gases like carbon dioxide and methane that are trapped in the atmosphere by clouds, enhancing the natural greenhouse effect. It notes global warming could significantly impact the environment, food, water, weather, health and more within 100 years if left unaddressed, and that industries like energy, agriculture, and tourism may be affected.

up the earth

6. How does it happen?
