  • Essay / How greenhouse gases increase atmospheric temperature

    Trapped greenhouse gases increase the temperature of the atmosphere, oceans and land masses, creating a ripple effect that disrupts the cycle rains, causing more heavy precipitation. Subsequently, due to trapped greenhouse gases, the Earth's temperature increases; which makes it much hotter than it should be. The increase in temperature in turn melts the polar ice caps, causing sea levels to rise; as a result, more land is lost by being swallowed up by the Earth's increasing water mass. The natural ecosystem is then negatively affected by extreme weather and rising sea levels. For example, animals that live in the tropics can see their habitat destroyed by violent typhoons, while animals like polar bears lose their habitat when ice caps melt. According to the U.S. Environmental Protection Agency (EPA), “the global average temperature has increased by more than 1.4°F over the past century.” (Climate Change Facts, EPA). Of the 100% of energy that the Earth receives from the sun, only 30% is absorbed by the Earth, while the remaining 70% bounces back. The earth then emits absorbed energy because it is significantly hotter than the sun; However, greenhouse gases prevent this from happening, causing the Earth to warm. In addition to natural sources of greenhouse gases such as volcanoes, human activities such as deforestation have a reducing effect on greenhouse gases. This is evidence that the Earth's temperature has increased due to trapped solar radiation that enters the atmosphere but cannot escape. The latest global environmental problem is overpopulation; this is when a specific population exceeds the optimal capacity of its ecological niche. As mentioned before, humans are in the middle of paper...... the year 1999 was 6 billion and predicted that by 2050 they will be 9.2 billion and further increasing over the years. This is an important problem because if people do not use contraception or implement proper family planning, natural resources will be depleted. The UN has stated that if fertility is not maintained at 1995-2000 levels, the world will suffer from overpopulation, reaching 244 billion by 2150 and 134 trillion by 2300. In addition, the he human population has increased. pollution in many third world countries. For example, the rate of overpopulation in Africa is very high and as a result, many live unhappily and are prey to disease. For example, because family planning is not practiced and medicines are difficult to access, diseases such as malaria and HIV are widespread across the continent...
