In the last century, the earth’s surface temperature has increased 0.45-0.60 degrees

celsius. Although some scientists believe global warming is not a problem, many

scientists believe that global warming is a serious problem, and can not be ignored.

Global warming, as the term implies, is the increasing temperature of earth. A

factor that is believed to play a part in this is the greenhouse effect, which is the

effect in which greenhouse gasses, such as carbon dioxide allow incoming solar

radiation to enter into the earth’s atmosphere, but prevent part of the infrared

radiation from the earth’s surface, and lower atmosphere from escaping into outer

space.The greenhouse effect, makes it possible to live on earth, as without it, life as we

know it would be impossible. The temperatures here on earth would be too low for

survival. However, with the greenhouse effect, the earth’s average temperature is

60 degrees fahrenheit. However, the global warming problem lies in the greenhouse

effect, many believe.

As the amount of “greenhouse gasses” in the air increases, so will the power of the

greenhouse effect. The major greenhouse gasses are carbon dioxide, methane, and

nitrous oxide. For instance, the concentration of carbon dixoide in the air since the

beginning of the industrial revolution have increased 30%, with nitrous oxide

concentrations increasing as much as 15% in some areas.

Believers of global warming fear the effects global warming can have on society.

They fear that the warming will eventually cause the ice caps to melt, with the sea

levels rising. Evidence of global warming is that sea levels have risen 4-10 inches

over the past century worldwide. However, rising sea levels are not the main

concern of global warming.

As a result of these other effects in earth, the fear lies in the fact that along with

these effects, there is an excellent chance that with this, a widespread outbreak of disease in both humans and animals will occur. These serious disasters,

scientists believe, is reason enough to be alarmed by global warming.

However, some people still feel there is nothing to be alarmed by. We call

these, the skeptics. The skeptics of global warming believe that the ice caps and

coast-lines are by no means, in danger of melting away or disappearing. They feel

that the earth’s warming is nothing to fear. Climate models of global warming are

believed to be mis-represented by the skeptical point of view. The skeptics are also

knowledged of the temperature fluctuating throughout time. Another thing that may

be contributing to the global warming scare is that the temperatures are read mostly

in cities, or airports. In both places, temperatures have potential to be much higher.

However, one can not ignore the evidence. The temperatrure has definitely

increased in the places that it has been measured from, and the sea level has risen.
