Global Warming Skeptics

Skeptics of global warming think that global warming is not an ecological trouble. According to the global warming skeptics, the recent enhancement in the earth's average temperature is no reason for alarm. According to them earth's coastlines and polar ice caps are not at a risk of vanishing. Global warming skeptics consider that the weather models used to establish global warming and to forecast its impacts are distorted. According to the models, if calculations are made the last few decades must have been much worse as compared to actually happened to be.

According to the global warming skeptics temperature rises happened before the extensive discharge of carbon dioxide in the middle of the 20th century. According to the skeptics, the earth’s climatic system is far stronger than being effected by minor changes in the emission of carbon dioxide. Also if CO2 reasons to global warming, then the warmed air should rise, dipping air pressure at the surface. All this has never been observed. Also according to the skeptics the nature of observations of the global warming scientists is not actually correct because most of the observations are taken in cities or airports where temperatures may be skewed higher.

Most of the global warming skeptics believe that the global warming is not actually occurring. They stress on the fact the climatic conditions vary because of volcanism, the obliquity cycle, changes in solar output, and internal variability. Also the warming can be due to the variation in cloud cover, which in turn is responsible for the temperatures on the earth. The variations are also a result of cosmic ray flux that is modulated by the solar magnetic cycles.

The global warming skeptics are of the view that the global warming is a good phenomenon and should not be stopped. There are various benefits of global warming according to them. According to the skeptics, the global warming will increase humidity in tropical deserts. Also the higher levels of carbon dioxide in the atmosphere trigger plant growth. As predicted, due to the global warming the sea levels will rise. But this can be readily adapted. Another argument of global warming skeptics is that earth has been warmer than today as seen in its history. The thought is that global warming is nothing to get afraid of because it just takes us back to a more natural set of environment of the past. Animals and plants appeared to do just fine in those eras of warm climate on the earth. According to few skeptics, the present chilly climate on the earth is an abnormality when judged over the geographical scale. Over geologic time, the earth’s mean temperature is 22 degrees C, as compared to today's 15.5 degrees C.

The global warming skeptics say that the attempts to stop global warming will do a greater harm. Global warming is much better than the mitigation strategies and Kyoto protocol, which is an international agreement to cut global warming emissions. According to global warming skeptics, the scientists that are involved in the climatic study are just making the matter of global warming, as a way of gathering publicity for themselves.
