A Ten Year Contradiction

For the past seven blogs I have argued that Global Warming does exist, and given facts to support this.  However, recently I found a little gem by a journalist Timothy Ball, explaining that global temperatures have on average been decreasing for the last ten years. His article can be found here. http://www.canadafreepress.com/2007/global-warming020507.htm
  The article explains that there was a period of cooling that began in the 1600's known as the Little Ice Age.  Global temperatures at this time were also cooler on average, and that several such small fluctuations have occurred in the past.  These fluctuations, according to Ball, are the result of changes in the sun.  At first I was very impressed with this article, until I tried to find further sources to validate his information.  According to one of my previous blogs, the same source explaining earth's axil tilt also discussed the rise in temperature for not just one but several past decades.  While it is true that within the last ten years, temperatures have gone down some half a degree, Farenheight, over the past fifty years, average temperatures have risen between two and three degrees, Celcius. In case anyone was unfamiliar, a difference in a Celcuis degree is around two and a third in Farenheight. Not only does Bell's article make a mountain out of a molehill, he also degrades the idea of a university.  He does raise a good point about political corruption of ideas, but the hard data doesn't back up his claims well at all. The only example he gives that denies the possibility of a warming climate are the last ten years of temperature data from scattered weather stations. 
  I am willing to accept any sort of denial for such a grave view of where the earth is going, but if the most popular source of information against global warming are opinionated articles set more on downgrading people trying to protect the planet from our own mistakes than finding real data of their own. 
  It makes me wonder, what if Global Warming IS nothing but a giant hoax?  Well, all we can be left with after trying to fix the planet is cleaner air, more fuel efficient vehicles and water that doesn't get entire third world countries sick with Cholera.  The earth is the only place we have to live, and if there's even a tiny chance it's in danger, isn't that something worth worrying about?
