Global warming is an increase in the average temperature of the earth's atmosphere. Many people believe in these statements, but there are many people around the world that refuse to believe that human contributions are the main cause of global warming, saying that the increase is part of the natural climatic change of earth.

Some people do support this issue, like John Christy, director of the Earth System Science Center at the University of Alabama in Huntsville. Christy says, "The carbon dioxide from fossil fuels is distributed evenly around the globe and not concentrated in the Arctic, so we can't blame greenhouse gases for the Northern Hemisphere warming over the past 27 years. The most likely thing for global warming is a natural climate change or cycle that we didn't expect or just don't understand”. People have
