Global Warming: An Inconvenient Truth

It was not only the people of the United States of America but the whole world was awakened when the documentary slide presentation turned film, An Inconvenient Truth by former Vice President Al Gore was shown in theaters on the 24th of May, 2006.The film persuasively contrives the science of global warming with Al Gore's effort of conducting lectures to different universities in different states and in different parts of the world.This has been his remarkably passion since he was in college.When Al Gore was asked by Oprah Winfrey about global warming in her show "Oprah," he explained:"As humans add pollution like carbon dioxide (also known as CO2) into the air, the Earth’s atmosphere becomes thicker. The thicker atmosphere traps more of the reflected radiation, raising overall temperature. This process is what we call “global warming.” Other major factors adding to global warming, Gore says, include the burning of coal, oil, gasoline and forests.
However, a number of scientists threw their punches to Al Gore;s argument.His contemporary stand about global warming is said to be very weak and that what he implies about carbon dioxide as one contributing factor in the changes of the Earth;s temperature is mute.Professor Tim Patterson, a paleoclimatologist from Carletone University, as he appeared before the Commons Committee on Environment and Sustainable Development in 2005, addressed that ;there is no meaningful correlation between (CO2) levels and Earth’s temperature over this [geologic] time frame.In fact, when CO2levels were over ten times higher than they are now, about 450 million years ago, the planet was in the depths of the absolute coldest period in the last half billion years.”Patterson asked the committee, “On the basis of this evidence, how could anyone still believe that the recent relatively small increase in CO2 levels would be the major cause of the past century’s …
