GREEN HOUSE EFFECT 6 The greenhouse effect refers to the change in the steady state temperature by the presence of an atmosphere containing gas that absorbs and emits infrared radiation. The greenhouse gases trap heat within the surface-troposphere system. Water vapour, carbon dioxide, ozone, methane, nitrous oxide, and chlorofluorocarbons absorb heat and trap heat within the surface-atmosphere system, leading to increase in atmospheric temperature. Nitrogen, oxygen, and argon make up 98 per cent of the atmosphere, but they do not absorb significant amounts of infrared radiation. Thus, these gases do not contribute to the greenhouse effect. Of the greenhouse gases produced by humans, carbon dioxide (CO2) contributes the bulk of radioactive forcing. Increased industrial activity (fossil fuel burning) and other human activities such as cement production and tropical deforestation have increased its concentration in the atmosphere. The concentration of carbon dioxide (CO2) in the atmosphere has increased from 285 ppm at the end of the nineteenth century, before the industrial revolution, to about 385 ppm in the new millennium. This increased emission, particularly of CO2, has affected the natural balance. Excess CO2 remains in the atmosphere, generating abnormal heat. This imbalance results in climate change. Unpredictable weather has an adverse impact on habitats across the world as well as sustainable development.
SUN 1 Solar radiation passes through the clear atmosphere. ATMOSPHERE 2 Some Solar radiation is reflected by the atmosphere and Earth’s surface GREENHOUSE GASSES 4 Some of the infrared radiation is absorbed and re-emitted by the greenhouse gas molecules. The direct effect is the warming of the Earth’s surface and toposphere. Surface gains more heat and infrared radiation is emitted again 3 Solar energy is absorbed by the Earth’s surface and warms it and is converted into heat causing the emmission of longwave (infrared) radiation back to the atmosphere EARTH 5 Some of the infrared radiation passes through the atmosphere and is lost in space 1
