And its used to grow plants that need high temperatures. This is to illustrate an example of howman could be causing changes to the climate. These changes result from increasing the carbon dioxide levelsin the atmosphere, thus raising the surface temperature of the Earth. And this is known as the GreenhouseEffect.CO2 is a normal component of the atmosphere and until recently has not been considered an air pollutant.But average global CO2 concentrations have been increasing since 1860, with particularly sharp increase in1958. The main reason for this continuous increase in CO2 build-up is the burning of fossil fuels. During thepast 100 years, the CO2 content of the atmosphere has already risen by about 15% - from about 290 to about340 parts per million. And its still rising.Although the CO2 content of the atmosphere is only about 0.032%, its a major factor in determining averageg lobal temperature. Incoming sunlight consists of many wavelengths including some very dangerous ones.But ozone in the upper atmosphere and water vapor and CO2 in the lower atmosphere filter out or destroymost of the harmful wavelengths, so what reaches the Earth is mostly visible light. Its absorbed by land, seaand cloud and is reradiated in the atmosphere as longer wavelength infrared radiation, or heat, as t he Earthcools. Much of this infrared radiation is absorbed by CO2. The CO2 then radiates a portion of the absorbedheat energy back to the Earth to warm the atmosphere. Rather like the glass in a greenhouse or a car windowo n sunny day, CO2 in the atmosphere acts as a one-way filter that allows visible light to enter the Earthsatmosphere, but prevents longer wavelength heat radiation from leaving. Assuming that energy is arrivingfrom the sun at a constant rate, then as the level of CO2 increases, the average surface temperature of the Page 1 of 4 Mã đề 002earth should rise.9.
