essay on global warming
Answers
Global warming is working like a demon on the earth as it is warming the planet continuously year by year. Actually, global warming is not created itself, it is a man created demon affecting the whole world gradually but regularly. There is an increase in temperature of the whole planet by around 0.8 degree Celsius however it is estimated to be raised more by the end of 21st century (around 2-5 degree Celsius). Global warming is a big trouble to all of us and animals including plants and other living beings.
Global warming is getting worse day by day because of the phenomenon known as greenhouse effect. Greenhouse effect is caused by the green house gases like carbon dioxide and methane which trap heat inside and make earth’s environment hotter. Green house gases work like the curved glass around the planet. Natural greenhouse effect is good for the planet as without it earth may be too cold and do not support the diversity of life here. However, huge increase in the amount of green house gases by the human activities is not good as it is creating gigantic effects all over the planet.
Earth’s temperature starts increasing. This happens because industry, fossil fuels, agricultural processes caused by human, natural, and other gas emissions, this factors increase greenhouse gases, greenhouse gases are made up of carbon dioxide, methane and nitrous oxide. The greenhouse gases stay in the atmosphere and prevent the suns warming rays to leave the Earth. So the sun’s warming rays stay inside the Earth increasing its average temperature. Global warming isn’t the end of the world, it’s just a natural process in which the Earth cleans or rinse organisms.
Now a days the Automobiles, heat from homes and businesses, and factories are responsible for about 80% of today's carbon dioxide
Lastly many bodies of water become polluted thanks to all the gasses in the atmosphere that mix with the clouds and fall as acid rain polluting rivers, and lakes and killing many animals. All of theses factors change our daily life and can ruin whole species, and all of this is because of temperature changes.
Many scientific methods of controlling or lowering the Earth’s temperature are being researched; these can also be called geoengineering. Geoengineering is a method in which scientists can change the levels of greenhouse gases directly or indirectly. Also there could be methods that prevent greenhouse gasses to be emitted. There have never been any geoengineering solutions done on a global scale since it has to be almost proof less. But there have been some ideas that are being use on a small scale like the iron fertilization; this is a process in which iron is injected into the oceans to speed up the reproduction of plankton which breath carbon dioxide and emit oxygen, this is one solution that seems to have the least side effects thanks to the reason I just presented and also due to that plankton are the base of many marine animals food chain. So this method is being widely researched to see if it can be done on a global scale. Not only is lowering the levels of gases in the air important,
