<u>Global Warming</u>
Global warming is the long-term rise of temperatures in Earth's climate. Global warming is caused mostly by increasing pollution. The pollution, whether from nonrenewable energy sources, farming, or deforestation is sending carbon and other greenhouse gases into the environment. The gases are part of the greenhouse effect, which traps the warmth from the sun in the earth. Global warming will cause melting of glaciers and ice sheets which will rise ocean water levels, flooding many coastal areas and cities. That is only one problem of global warming. Global warming is on the rise and the effects are very dangerous.
