What is Global Warming?

Global warming is the increase of the temperature on the earth. This increase is caused by humans who burn fossil fuels. The gases that are produced by the burning are trapped in the atmosphere and cause pollution. When the gas is stuck, the heat increases and the light does not reflect away from the earth.
As a result of global warming the sea level rises and the air gets polluted. People get affected by these results because less drinking water is available, and many plants and animals die because of the heat.
Some countries are worried and think that it is a major problem, and as a solution they put laws on factories and companies to decrease the amount of fuel that is burned. Many countries do not care about this danger and continue burning and increasing the global problem.
