Is global warming man made - Essay Example

In short, nobody has any doubt about the fact that atmospheric temperature is showing abnormal increases in recent times. On the other hand, many people believe that global warming is a scam or manmade issue in order to exploit the sentiments of people for commercial purposes. “Global warming skeptics consider that the weather models used to establish global warming and to forecast its impacts are distorted”1. They are of the view that some scientists raise this issue in order to make money in the name of global warming researches.

This paper critically analyses whether global warming is manmade or not. Prominent scientists, such as Frederick Seitz, Ph.D., Richard S. Lindzen, Ph.D., S. Fred Singer, Ph.D, Patrick J. Michaels, Ph.D. and Robert C. Balling, Jr., Ph. D.2 have expressed doubts over climate change and challenged the consensus of mainstream scientists3. Greenhouse gas emissions from automobiles and industrial units are often cited as the major reason for global warming. According to scientific principles, gases in atmosphere should expand when they get heated and travel in the upward direction.

If that is true, air pressure at earth’s surface should be dipped. However, such dip in atmospheric pressure near earth’s surface has been never observed. . Also the warming can be due to the variation in cloud cover4. Lord Crimson (n. d) has quoted the opinions of 19,000 scientists in order to reject the idea of global warming. He has pointed out that these scientists are of the view that global warming is probably natural and not a crisis5. It should be noted that it is impossible for mankind to make any changes in in solar output or variations in cloud cover.

Under these circumstances, the opinion of meteorologist John Coleman, founder of the Weather Channel, is very much important. He said that “even if global warming is something to worry about, it's dangerous to look to government to fix the climate”6. Stephen Mulholland (2009) approached global warming issue from a different angle. In his opinion, “We have one of mankind's greatest scams: climate change and anthropogenic global warming (AGW), in which we're asked to expend trillions of dollars now so that events which may, or may not, take place when we've been dead for centuries don't take place”7. In Dr. Sami Solanki’s (the director of the renowned Max Planck Institute for Solar System Research in Gottingen, Germany) opinion, “Sun has been at its strongest over the past 60 years and may now be affecting global temperatures”8.

In other words, we have to look upwards to identify the villain who causes global warming instead of looking around. Some scientists believe that the intensity of solar radiations increases and decreases periodically in every 1000 years of time period. In their opinion, sun is currently going through a period in which its radiations are intensified and there is nothing to worry about it since such increases in temperature may not go beyond certain
