Global warming is a major issue all over the world |
Global warming is a major atmospheric issue all over the world.Our Earth's surface becoming hot day by day. The brightness of the sun continues to increase as the star ages and it passes on an increasing amount of this energy to Earth's atmosphere over time.'Global warming' denotes a rise in the Earth's average temperature.The primary cause of Global warming is the Green house effect, that is the entrapment of green house gases between the ozone layer and the surface of the earth, creating more heat by the day.The green house gases build up in the atmosphere the earth gets hotter. Green house gases are water vapour, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons.Green house gases traps the solar rays and prevents them from escaping the surface of the earth.
Burning fossil fuels like coal and oil puts more carbon dioxide into our atmosphere. Methane, a powerful green house gas, able to absorb far more heat than corbon dioxide. It is found in very small quantities in the atmosphere but it is able to make a big impact on warming.Rearing cattle also causes the release of methane from manure. Nitrous oxide is released from bacteria in soil. Modern agricultural practices-tilling and soil cultivation, livestock waste management, and the use of nitrogen rich fertilizers-contribute significantly to nitrogen oxide emission.
Causes of Global warming
Green house gases, variations in the sun's intensity, Deforestation, rapid industrialization, transportation, agricultural activity, termal power plants,increased using excessive automobiles, mining activities, respiration, volcanic eruptions, fossil fuels combustion
Effects of Global warming
Rising temperature, melting glaciers, rising sea levels, drastic change in rainfall patterns, depletion of the ozone layer, increased droughts, wild fires, floods, tropical storms,natural disasters, loss of wildlife and biodiversity.Animal populations are vanishing as there has been a wide spread loss of their habitat.
Solutions of Global warmingSolutions for global warming will be more effective when individuals change their life styles. Planting more trees can be a good step towards removing the problems of global warming.plants use carbon dioxide to ptepare their food and release oxygen as a by-product.To reduce global warming we can contribute by reducing the production and concentration of green house gases in the atmosphere. Recycling can help reduce open burning of garbage by reusing plastic bags, bottles, papers or glass. We must adopt an eco-friendly life style to make the future safe for our future generations.
