María Paula Rodríguez Peñaranda - 2170061 1.What natural factors affect global warming? Natural factors do not affect global warming, because if they were, then the response to natural factors should match the observed temperature. If you add the natural factors together you simply don’t add them. It really is the greenhouse gases that contribute to global warming. 2. How do these natural factors contribute to global warming? Please explain briefly. Greenhouse gases heat the atmosphere. Aerosols cool it down. Ozone changes and land use add and subtract a bit. Together they match the temperature observed, particularly since 1950. 3.What are the human factors that have the least impact on global warming? Humans have cut, plowed and paved more than half the earth’s surface. Dark forests are yielding to lighter patches, which reflect more sunlight, and have a slight greenhouse effect. Some pollutants cool the atmosphere, such as sulphate aerosols from coal burning. These aerosols offset so
