Global warming is a gradual increase in the temperature of the earth surface and atmosphere all around the world. It is caused due to the greenhouse effect of increased level of green house gases such as carbon dioxide, CFCs, etc. There are various types of pollutants also which involved in increasing the atmospheric temperature of the earth. Increasing use of fossil fuels by the people and deforestation is increasing carbon dioxide emissions which trap heat and cause greenhouse effect. Water vapor is also a significant greenhouse gas which is not directly produced by humankind but involve in global warming hugely. A slight increase in the level of CO2 causes marked increase in earth temperature. Green house gases absorb and re-radiate infrared radiations which ultimately cause green house effect. Because of deforestation, CO2 is not absorbed well and remain in the atmosphere for long time and trap heat. Carbon dioxide is one of the main green house gases, the increased amount of which is causing a warming effect on the earth surface which in turn causes evaporation of more water and creates water vapor (a type of greenhouse gas). In this way, the level of green house gases in the atmosphere are increasing and creating more warming effect. CO2 level is also increasing because of the burning fossil fuels. Other green house gases like Sulphur, CFCs, Methane, etc are also responsible for increasing global warming. The level of these gases is increasing due to the population growth, urbanization, industrialization, technological advancement, and deforestation. Impacts of global warming differ from region to region all over the world. Retreat of glaciers, sea ice, more frequent extreme weather events, heat waves, heavy rainfall and snowfall, droughts, floods, ocean acidification, species extinctions, etc are some huge impacts of shifting temperature regimes. In order to reduce the effect of global warming, effective societal responses are needed to be implemented and followed urgently. Global warming has now been a serious problem and we need to fight that with our positive and environment friendly activities. We need to take proper initiatives in order to save our mother earth and to do that we have to stop CO2 emission to a great extent. It is possible if we reduce the use of oil, fuel, coal, gases, etc and concentrate on renewable energy usage. Tree plantation is also a big positive initiation to reduce global warming as trees absorb CO2 in the environment and generate more oxygen; however, we need to bring a lot of habitual changes in our daily life.
Global Warming [ 500 Words]
Global Warming is a phenomenon that is occurring every minute resulting in a gradual increase in the Earth’s overall climate. Brought about by greenhouse gases that trap the solar radiation in the atmosphere, global warming can change the entire map of the earth, displacing areas, flooding many countries, and destroying multiple lifeforms. Extreme weather is a direct consequence of global warming but it is not an exhaustive consequence. There are virtually limitless effects of global warming which are all harmful to life on earth. The sea level is increasing by 0.12 inches per year worldwide. This is happening because of the melting of polar ice caps because of global warming. This has increased the frequency of floods in many lowland areas and has caused damage to coral reefs. The Arctic is one of the worst-hit areas affected by global warming. Air quality has been adversely affected and the acidity of the seawater has also increased causing severe damage to marine life forms. Severe natural disasters are brought about by global warming which has had dire effects on life and property. As long as mankind produces greenhouse gases, global warming will continue to accelerate. The consequences are felt at a much smaller scale which will increase to become drastic shortly. The power to save the day lies in the hands of humans, the need is to seize the day. Energy consumption should be reduced on an individual basis. Fuel-efficient cars and other electronics should be encouraged to reduce the wastage of energy sources. This will also improve air quality and reduce the concentration of greenhouse gases in the atmosphere. Global warming is an evil that can only be defeated when fought together. It is better late than never. If we all take steps today, we will have a much brighter future tomorrow. Global warming is the bane of our existence and various policies have come up worldwide to fight it but that is not enough. The actual difference is made when we work at an individual level to fight it. Understanding its import now is crucial before it becomes an irrevocable mistake. Exterminating global warming is of utmost importance and each one of us is as responsible for it as the next.
