Include changes in Soil, Biosphere, Oceans, and Lithosphere 2. These are very fine particles and droplets that are small enough to remain suspended in the atmosphere for considerable periods of time. They both reflect and absorb incoming solar radiation. Changing the type and quantity of aerosols in the atmosphere affects the amount of solar energy reflected or absorbed. Human Factors Affecting Climate 1.
Scientific studies show that a variety of human activities release greenhouse gases.
These include the burning of fossil fuels for producing electrical energy, heating and transportation. By increasing their concentrations and by adding new greenhouse gases like CFCs, humankind is capable of raising the average global temperature. As humans replace forests with agricultural lands, or natural vegetation with asphalt or concrete, they substantially alter the way the Earth s surface reflects sunlight and releases heat. All these changes also affect regional evaporation, runoff and rainfall patterns. Land use changes also affect carbon cycle and atmospheric aerosols.
