Controlling Global Warming and Concluding Climate Change by Reflection of Sunlight- Revolutionary or Devastating Idea?

For the progress of modern civilization using ground breaking research and development in the field of science and technology it is amazing to see that humans have learnt no limit and have achieved greater heights each day. But in the process of the scientific, technological and industrial developments human have compromised with their own home planet. The progressing civilization and industrialization is mercilessly releasing poisonous gases in atmosphere which in turn is altering the climate of Earth. These gases are known as greenhouse gases and the effect cause by these gases is known as greenhouse effect. Greenhouse effect can be described as the global rise in Earth's average temperature due to an imbalance in the amount of incoming solar radiation and outgoing terrestrial radiation caused by the green houses, mostly carbon dioxide. Millions of tons of carbon dioxide is released each day in the atmosphere mainly from industries and vehicles which allows the sun's incoming radiation to fully pass but absorbs good amount of outgoing radiation after reflection from the Earth's surface. The full incoming radiation energy cannot escape due to partial absorption by the greenhouse gases causing rise in Earth's global average temperature known ads global warming. The global average temperature has alarmingly raised than few decades ago drawing attention of global community. Countries worldwide are now campaigning and trying to control global warming by cutting down their poisonous emissions by converting those harmful greenhouse gases into less harmful ones before releasing in the atmosphere. But we have already harmed our planet so much that it will take many years for the Earth's global average temperature to be normal again. The global warming has greatly affected the normal climate of the Earth which is drastically changing now towards worse and hampering the global ecological balance. Scientists and researchers worldwide are deeply concerned with this fact now are trying to figure out solutions to reduce global warming and bring back the Earth's climate to its original condition. 

Human civilization never lack innovative and ground breaking thoughts and ideas which have lead to their evolution from stone-age beings to modern homo-sapiens. This is again reflected from the mind blowing concepts and ideas for preventing global warming and climate change by reflecting the light of the sun, as an ultimate desperate measure after failing to control alarming level of climate change. But the question lies in the fact whether this innovative idea for reflecting sunlight to stop global warming and climate change will come with revolutionary or devastating results. Some researchers pointed out the incident of eruption of Mount Pinatubo in 1991 as nature's illustration of controlling global warming. The hot ashes and gases after eruption spread in the upper atmosphere globally reflected the sun rays and cooled the planet naturally for more than a year. The idea from this is to spray aerosols using airplanes that can reflect the sunlight. One hypothesis says it will protect the crops from the extreme heat waves. But a recent publication in Nature using data from the historical eruption of two volcanoes concluded that changing the atmosphere accordingly would have no net effect on the crop yield. By altering the atmosphere though the crops will suffer less heat waves but they will also receive less photosynthesis-powering sunlight. Though no such technology exists now but it can be developed in due course for example by powering planes with special fuels to burn sulfur and spray aerosols in atmosphere. If this mega-project is undertaken in future then efficient ways have to be developed to maintain constant aerosol level in the atmosphere. The fluctuation of aerosol level will cause sudden heating and cooling and will adversely effect the Earth's habitat and ecosystem. Many other researchers are of the view that it is better not to tamper the Earth's atmosphere as it can lead to devastating consequences for mankind. The best way is to stop treating Earth as 'deposit ground' of our sewage and reduce the emission of harmful greenhouse gases to as low as possible by proper filtration of smokes and fumes before discharging them in the atmosphere. It is also necessary to plant as much amount of trees as possible rather than cutting them down to expand our own civilization. We all know that trees are the best source of filtration of carbon dioxide as they absorb lots of carbon dioxide during day time and release oxygen for us to breath. We have already harmed our Earth and changed its climatic conditions to an alarming level. Taking these steps determinedly can bring the global average temperature and climatic conditions back to normal but it will take few decades. This is the only natural process we are left with to save our Earth from destruction but our intervention by altering its atmosphere can lead to more devastating consequences.
