Global Warming is the measurable increases in the average temperature of Earth’s atmosphere, oceans, and landmasses. Scientists believe Earth is currently facing a period of rapid warming brought on by rising levels of heat-trapping gases, known as greenhouse gases, in the atmosphere.
Greenhouse gases (like carbon-dioxide, methane, carbon-monoxide, sulphur-dioxide, nitrous-oxide etc.) occur naturally, and without them the planet would be too cold to sustain life as we know it. Greenhouse gases retain the radiant heat provided to Earth by the Sun in a process known as the greenhouse effect. Since the beginning of the Industrial Revolution in the mid-1700s, however, human activities have added more and more of these gases into the atmosphere. For example, levels of carbon dioxide, a powerful greenhouse gas, have risen by 35 percent since 1750, largely from the burning of fossil fuels such as coal, oil, and natural gas. With more greenhouse gases in the mix, the atmosphere acts like a thickening blanket and traps more heat. Unfortunately human activities such as burning fossil fuels, destruction of forests, releasing harmful chemical in the atmosphere are disrupting this natural process, with potentially dangerous consequences such as Global Warming and Climate Change.
The rise temperature of earth is melting down polar ice caps. As a result sea level is rising and soon coastal areas of many countries and some island nations will completely go under water killing a lot of people and displacing many more. Due to this Global Warming the intensity and frequency of natural disasters are increasing, that is the storms are getting stronger and they are occurring more often. Besides that, polluted air causes diseases such as lungs cancer, bronchitis, asthma and other respiratory problems. Diseases such as Tuberculosis, Pneumonia are also caused by contaminated air. The rise in temperature is also changing the climate which is destroying natural habitats of animals and plants. The food chains are disrupted and one by one endangered animals and plants are going extinct. If this process of extinction continues then soon it will be our turn to go extinct.
If the Global Warming continues to increase our home planet Earth would become inhabitable soon. We hope that we will be able to check Greenhouse Effect to ensure human survival.
