    In this article I will be discussing about the global warming which has become a very im-portant topic among the leading scientists and the common people as well. As portrayed bymany researchers of various fields,global warming is mainly the increase in average tempera-

    ture of the environment of earth,which is expected to be very much dangerous and harmfulto the life on earth. Many people has various viewpoints towards this issue and after watch-ing the two videos on global warming which have completely opposite viewpoints, I will tryto describe my own understandings and conclusions regarding the global warming in thisarticle.

    As depicted in the movie An Inconvenient Truth,there can be devastating consequencesof the increase in average temperature of the world. There can be many fluctuations in theweather of various places, mainly in coastal regions such as Central America, Japan, etc.due to global temperature increase and its effect on ocean currents. But before concludingabout the reasons and blaming the human activities for these calamities, we should try to

    understand what are the natural factors behind this and compare them with the factorsintroduced by human activities. As correctly depicted in the movie The Great GlobalWarming Swindle the natural factors affecting the temperature of the earth are far morepowerful than the factors created by human activities.

    I will try to back this viewpoint by first listing out the factors which are affecting thetemperature change and are mainly controlled by humans.These factors can be large numberof industries giving out greenhouse gases in a large amount, vehicles driven by us which emitsgreenhouse gases, rapidly increasing rate of populations which contributes in the major chunkof artificial Carbon dioxide emission, cutting of trees and vegetations which were supposedto maintain the balance of Carbon dioxide and Oxygen in the air. These are the majorfactors which increase the amount of greenhouse gases in the air and are being controlled bythe human activities. Now I will try to list the natural factors contributing to the amountof greenhouse gases in the air. Gases regularly being emitted by volcanoes, Carbon dioxidebeing emitted by the trees during night and most importantly the huge amount of life insidethe ocean emits Carbon dioxide as well and this definitely is not a small amount as only30% of earths surface is covered in land and 70% is water and inside the huge ocean thereare many known, unknown living beings who gives away Carbon dioxide. These amount ofgreenhouse gases which cannot be controlled by humans are not at all small compared tothe greenhouse gas contribution by human activities. Another important factor mentionedin the moive The Great Global Warming Swindle is the role of the Sun in controlling thetemperature of the earth. This doesnt need any proof that Sun can control the averagetemperature of the earth where all the seasons in a year are being controlled by the Sun. Sothe fluctuations on the surface on sun can largely effect our environment, not only by raisingtemperature but by many other means of radiation as well.

    So my argument is that the amount of greenhouse gases are somewhat controlled by thehuman activities but mainly controlled by natural activities on earth and without consid-ering the effect of greenhouse gases, temperature of earth itself is being controlled by thefulctuations in the radiation of the Sun which are due to solar flares. There has been manypredictions about the solar flares and the prediction of scientists were that the solar flareswould reach their peak intensity in 2013 starting from the middle of 2012. If we try tointerpret the recent data, we can easily visualise and feel the raise in average temperatureand fluctuations in the time periods of seasons in different parts of the world which can only

    be reasoned by solar flares. This is the proof which enables us to conclude the radiationfluctuations on the surface of the Sun as the most important parameter for the averagetemperature of the earth.

    So according to my understanding and by the presented data, predictions in both themovies, my conclusion would be that major reason in the global temperature increase orglobal warming is the natural causes such as solar flares of the Sun and human activitieshave very liitle contribution to the global warming. But I would like to address another issuewhich is also environmental and mainly controlled by human activities and at the same timedangerous and harmful like global warming.

    In the above descriptions I have depicted my deniel of considering the Carbon dioxideemission by human activities to be the major reason of global warming but that completelydoesnt mean that I am not against the unnecessary emission of harmful gases by the indus-tries and vehicles. These harmful gases includes oxides of Sulphur(SOx), Nitrogen(NOx),Ammonia, unburnt fuel which are very harmful for human body and can make permanentdamage to lungs and respiratory system. Even for other animals and plants these gases arevery harmful. In the industrial places concentration of these gases and Carbon dioxide is veryhigh which can cause breathing problem and not only temporary problems but permanentproblems of body parts as well. The waste materials from the industries creates soil polutionwhich directly effects our food that we take. So this is completely unjustified to emit thesepoisonous gases and wastes in an uncontrolled manner. In the later part of this article Iwill try to express my views regarding the monetary issues regarding global warming andactually what should be done.

    Another issue was rightly pointed out in the movie The Great Global Warming Swindle

    which is the investment of huge amount of money in development of new technologies andimplementation of other eco-friendly standards to reduce the emission of Carbon dioxide andother greenhouse gases. Accroding to me the motto should be to reduce the amount of thesegases not because they are involved in global warming but because they are permanentlycreating damage and harmful diseases in human bodies. Plants are most helpful in thissituation as there are several types of plants which reduces these gases from the environmentby using them in their own biological processes. Acid rain, Smog and many other poisonousenvironmental damages are due to increase in the amount of these harmful gases. So accrod-ing to me money should be invested to improve the technology and filtering processes in theindustries and other sources of such gases.

    Its the responsibility of the media and other government bodies to remove the fear ofglobal warming which is created by describing the devastating consequences of it. I certainlyagree with whatever consequence is being predicted but all the parameters which correspondsto human activities should be removed and the predictions should be refreshed. On theother hand its their responsibility to show the actual harmful effects of industrialization,deforestation and inefficient use of fuel, which has direct impact on human life. Finally Iwould like to conclude by saying that every human being on this planet should try to be asmuch efficient as possible in using the energy resources which is very important and I believethat reducing the pace of development by showing irrelevant and unjustified predictions aboutglobal warming is not at all acceptable, whereas efficient development should be encouragedwhich will lead our world to a stable and happily habitable place.
