Global Warming means that the earth is warming. Some causes on global warming is that there is too much pollution in the o-zone layer. Humans have been one of the main causes of global warming because of all the oil spills in the oceans and the pollution from cars and trucks. Mining coal and oil lets methane escape and makes greenhouse gases. Greenhouse gasses are also a problem for global warming. Greenhouse gasses are gases that occur naturally such as, water vapor, carbon dioxide, methane,and nitrous oxide. Methane, a greenhouse gas is making heat getting trapped in the earth's atmosphere. Andrew C. Revkin says that global warming has become perhaps the most complicated issue facing world leaders. Most of the information on global warming is going to be about evidence for global warming.
