Is Global Climate Change Really a Problem?

Recently on TV, in magazines, and on the radio there has been an extensive amount of discussion on global climate change and whether or not it is truly a problem worth adressing or if it is even a problem at all.  I have brought up this topic before, but never gone into much detail and have not presented the proper evidence for my opinion on the global climate change crisis.

Take a look at the graph above and analyze what you see.  Surprisingly to most people, what you will find is that in the year 860 earth's average temperature was actually higher than in the year 2007.  Yes it is 2009, and the average temperature is still lower than that of the Middle Ages, so why is it that all this commotion about greenhouse gas emissions and the human race creating global climate change still lingering?

For anyone to deny that greenhouse gases raise earth's temperature is ignorant, because they do, but to say that we are going to end up causing the ice caps to melt and a global flood or any of those theories is just as bad.  Notice after every up slope on the graph there is a down slope, and the opposite as well, so why is it that we are making a big deal about it.  Earth has fixed itself in the past, and will continue to do so.  It is illogical to say that all of a sudden the earth will stop doing what it has done for millions of years just out of the blue.  Honestly, I believe we should worry more about the next downslope and possible ice age that may follow where we are more than the current upslope.  Anyways, what if the ice caps did melt?  All that would happen is maybe an increase of about 8 inches in the total water level of our oceans.  That would hardly cause any damage, maybe a little, but not enough to constitute our exceedingly high level of concern in the topic.

What we really need to be doing is keeping an eye on the temperature, while focusing on more important problems of the present like the economy more than the environment.  There could possibly be a point when our average temperature does get too high, but that time is not now; all that is to high is our national debt.
