Global Warming is essentially the increase in the earth’s average temperature. As to what has been projected, the world would be completely swayed by its affect by 2100. Scientists, studying the subject, share the opinion that human activities, primarily the emancipation of green house gases from smokestacks, vehicles and flaming forests, are the leading causes for Global Warming. These gases not only allow sunlight to enter and help the greenhouse effect, but also stop some of the resultant heat from radiating back to space. Besides this, there are many more facts that throw light on the topic.
Facts /Causes of Global Warming
- The emission of green house gases is the strongest factor which is contributing to the ghastly disorder of global warming. Green house gases, such as, carbon dioxide, methane, nitrous oxide etc, are contributed mainly by human activities.
- Power plants are the major source of carbon dioxide, emitted by burning of fossil fuels.
- About 20% of carbon dioxide in the environment comes from gasoline, burnt in vehicles’ engines.
- Be it a residential or commercial, construction of buildings requires a lot of fuel to be burnt. It develops great amount of carbon dioxide in the atmosphere which ultimately results in warming.
- Deforestation, which is actually cutting and burning of forests intended for residence and industrialization, is another reason for global warming. Fewer trees indicate less carbon dioxide conversion to oxygen. Moreover, human beings are emitting carbon dioxide at a much faster rate than plants can absorb.
- Being the powerful trap of heat, Methane is 20 times more dangerous than carbon dioxide. Methane emits from resources, like rice paddies, bovine flatulence, bacteria in bogs and fossil fuel manufacture.
- Use of fertilizers, cars with catalytic converters, and burning of organic matter, also leads to emission of gas like nitrous oxide that ultimately acts as a heat trap.
- All these gases, whether carbon dioxide or methane, persist for years in the atmosphere, implying that even if such discharge are abolished now, it would not right away stop global warming.
- Concentrations of water vapor have been tremendously augmented by industrialization, deforestation, and pollution.
- Since water vapor structures 60% of the Greenhouse gases, it is also related to global warming.
- In the future, warming could become unmanageable because the increasing temperatures could release other greenhouse gases by releasing methane in permafrost and undersea deposits, emancipating carbon trapped in sea ice and causing augmented evaporation of water.
