The Telegraph reported "For many years now, human-caused climate change has been viewed as a large and urgent problem. In truth, however, the biggest part of the problem is neither environmental nor scientific, but a self-created political fiasco. Consider the simple fact, drawn from the official temperature records of the Climate Research Unit at the University of East Anglia, that for the years 1998-2005 global average temperature did not increase (there was actually a slight decrease, though not at a rate that differs significantly from zero)."
I believe the concept of 'Global Warming' is often used by certain groups and individual to promote some type of political agenda. I will be the first to agree that the weather seemed unusually bazaar over the last few years. I will also agree that we should reduce or eliminate the use of any form of pollution.
The real truth could be that our world is going through a standard shift in its climate. There are also natural forces that can cause climate changes, such as erupting volcanoes (i.e.: the Tambora volcano in 1815 in Indonesia), large asteroids hitting the earth (i.e.: the 1908 Siberia Explosion), etc.
All I am trying to say, is that sometimes we have to think different and be different. There are times we need to be the sheep and go with the crowd, and there are times we need to be the dog herding the sheep.
