Answer:
Global warming is the increase in the earths atmosphere from several things. Pollution is the main cause of this. "Global warming" is the overall effect and "climate change" is what is happening to our planet currently.The average global tempature is increasing at a very high rate and is getting worse very quickly. Scientists say that unless we slow down global-warming emissions, average U.S. temperatures could increase by up to 10 degrees Fahrenheit over the next century. Pollutants can last over a year in our atmosphere these pollutants trap the heat and cause our atmosphere to become warmer (green house effect). The biggest source of climate change is the burning of fossil fuel :coal, petroleum, natural gas, oil shales, bitumens, tar sands, and heavy oils.
