The ‘Mother Earth’ has been cooling for the last decade. Poles of the planet are gaining about as much ice as they are losing. It is worth mentioning that since past 420,000 years, Earth’s atmospheric temperature is changing even before carbon dioxide emission by humans. There is no scientific evidence to back claims of man-made global warming period. Anyone who tells you that scientific research shows warming trends – be they teachers, newscasters, Congressmen, Senators, Vice Presidents or Presidents – is wrong. In fact, scientific research through U.S. government satellite shows that the earth’s atmospheric temperature is actually cooling – very slightly by 0.037 °C. Generally carbon dioxide is considered to be a principle greenhouse gas. From 1998 until 2009 the Earth has cooled about 25 °C despite the fact that CO2 level has continued to climb up. Moreover, as the concentration of CO2 gas in the environment increases, the ocean has also increased its absorption of CO2 from roughly 2.0 Pg to 4.2 Pg. The readings taken for last three summers shows that the global sea level this summer is a quarter of an inch lower than last summer. Sunspots activities help provide an explanation for the continuous up and down jiggling of the earth’s temperature that even more complicates the problem. Changes in global temperatures are natural. This study has concluded that the global warming problem is not initiated by human kind. It was present already even before a century. This has been proved by the presence of 40% more oxygen in the atmosphere before 5.3 million years. Of course we, human being, are contributing a minor portion resulting to greenhouse effect. But, it is important to understand that this is Earth’s cycle which is natural. The paper intends to present the facts proving greenhouse effect and global warming are natural phenomena, not manmade. INTRODUCTION:
One of the fundamental tenets of our justice system is one is innocent until proven guilty. While that doesn’t apply to scientific discovery, in the global warming debate the prevailing attitude is that human induced global warming is already a fact of life and it is up to doubters to prove otherwise. Did you know that the Earth has been cooling for the last decade? Did you know that the poles of the planet are gaining about as much ice as they are losing? Did you know that for 420,000 years changes in the Earth's temperature have happened before changes in atmospheric carbon dioxide? These are not things that you are likely to learn by listening to the mainstream media…. GLOBAL WARMING AND ITS CAUSES:
Global warming is continuing rise in temperature of earth’s atmosphere and ocean. When we talk about global warming the first thing that comes to our mind is ‘Green House Effect’. Green house effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric green house gases (Water vapor, carbon di oxide, methane, nitrous oxide and ozone), and is re-radiated in all directions. Since part of this re-radiation is back towards the surface energy is transferred to surface and lower atmosphere. As a result, the temperature there is higher than it would be if direct heating by solar radiation were the only warming mechanism Its causes are as follows:
a) Anthropogenic (manmade) causes
b) Natural causes
a) Anthropogenic causes( according to manmade global warming theory): Anthropogenic causes for global warming are those which are caused due to human activities. The most prominent cause being man-made pollution. A large part of this pollution can be attributed to the burning of fossil fuels. This includes burning coal to produce electricity as well as burning gasoline to power internal combustion engine vehicles. When these fossil fuels are burnt,...
