All I know is I know nothing.

With all this complicating knowledge on what is true knowledge and what is not knowledge has got me all confused. I have been writing my social essay, I decided on the topic of Global warming. At first i believed global warming was caused by humans. then after some research discovered about world cycles related to the amount of magnetic variation the sun produces and there was alot of supporting evidence. However there was alot of supporting evidence that it is solely related to human gas emissions. So in my distress I went to an older friend (supposedly the elder are wiser) he told me that it is only warming up in some places its getting coled in some places as well so it is more or a climate change overall. He believed that the poles were just shifting, due to the amount of oil taken out of the ground. Lets do a thought experiment. Imagine a ball spinning around along an axis, now take a bunch of weight off of one side then the ball would not be balanced if it were spinning along the same axis the axis would end up shifting toward the heavier side so it to maintain its rotation. With these three points i have not an idea of what side i am supporting to do my essay on.
