There seems to be lots of questions on this global warming issue. Anonymous Guy and Andy just go back and forth quoting things that make there point of view true. It is like one of you saying the way to heaven is to follow the Koran and the others says to follow the Bible. Your only proof of who is correct comes from those books you are promoting. Is it possible that the Jews know the way to heaven too? To finish the analogy are human actions the absolutely only reason the Earth is currently warming? If not how much effect do human actions have on it?

I thought Pack04 brought up an excellent point. When I discuss Global Warming face to face with people, I don't have the ability to insert a hyperlink to make my case. Instead, I rely on logic, and hope to give the person some direction to go do their own research. I am going to do my best to do that here. Hopefully this will help shed some light on my thoughts on global warming, and might give you some food for thought.
A little about my background. I have been writing about global warming on here since 2007. I have been reading about the topic longer than that. I studied geophysics in college as a minor. Does that make me an expert in the field? Absolutely not. It does give me a few tools to understand some of the science behind the arguments. Truthfully, I think most of this debate can be understood by anyone, if they can keep a few points in mind. As you read the rest of this article, try to put aside what you currently know about the debate on global warming. Then, after reading this, go back to what you previously thought with, hopefully, a slightly different perspective.
First, it's important to remember that the Earth's climate and temperatures are constantly changing. If you could magically transport all humans, and every piece of our technology and pollution off the planet, the Earth would probably still be warming. At the very least, the temperature would continue to change. Before man arrived, the Earth went through natural warming and cooling cycles. This will continue long after we leave. The question both sides debate is: How much warming is due to man?
Secondly, remember that all future predictions (dire and otherwise) are based on computer models. Computer models are a very complicated set of predictions and assumptions an individual makes. In every other scientific or engineering field, once a computer model is created, it is tested with a known set of data with known results. For example: if you were creating a climate model, you might plug in data from 1900 to 1960 to see if your model could accurately predict the weather of the 1970's and 1980's. If it does, you have a good model. If it doesn't, your model still needs work. Here is the second important point: No model currently out there will predict previous years climate. None of them.
One of the assumptions built into climate models is how clouds act. Climatologists on both sides agree that clouds are an important component (some have argued they are a primary component) of what our climate does. However, climatologists don't understand how or why clouds form, or how and why the disappear, or even why they appear in some locations and not in others. As a third important fact, this means all computer models incorporate a guess on how clouds do what they do. This starts the model with an error before the first piece of data is entered.
Now let's pretend we could accurately predict the climate, and we knew it was in fact warming. That still doesn't end the debate. There is no proof that global warming is a bad thing. If the planet was to increase its temperature by 1 degree over the next 100 years, that might be beneficial. It could cause an increase in plant life and human life. Hot weather kills less than cold weather. If we knew a 1 degree increase might cause an additional 1000 deaths in the summer, but save 10,000 lives in the winter, would that be bad? This debate hasn't happened yet, and until it does, we shouldn't spend fortunes trying to correct something we don't really understand.
We aren't sure how accurate our predictions are, and we aren't sure if global warming would truly be a bad thing. Now, let's look at some solutions. If you have read about this topic, you are familiar with the Kyoto treaty. In a nutshell, the Kyoto Protocol is a international treaty that sets targets for reductions of greenhouse gases. The United States is has not ratified this treaty. However, if every nation in the world signed on to Kyoto and met its requirements, it wouldn't stop global warming. The best it would do is to reduce global temperature increases by approximately 0.01 degree Celsius. And this relatively insignificant reduction would come at a fortune of money, technology, and even quality of life.
However, just because I don't believe in man-made global warming doesn't mean there aren't solutions I would support. I do believe conservation is important. I recycle in my own home. I also believe that if the United States did a major push to increase our nuclear energy facilities, there would be a number of benefits. More US nuclear energy would mean more energy here, less money going over seas, more jobs in the United States, and if you believe in Global Warming, a clean energy source. I am always suspicious of people who claim to believe in man-made catastrophic global warming, but aren't willing to discuss more nuclear facilities in the United States. This is a compromise that should generate support form Democrats and Republicans alike.
The next time you read a global warming article (regardless of the point of view of the article) keep these points in mind. I think you might be surprised with what conclusions you reach on your own if you ignore the propaganda, and just look at the facts. Regardless, like any other issue, if you are going to make an informed decision, you will need to do some homework. I hope this helps to give you a framework to start digging around with.
