I think there is no denying that global temperatures are rising. Alaska is the perfect example of that by just looking at our glaciers. That being said, the earth has cycles. We have only been keeping accurate records for about 100 years. The possibility of there being a cycle larger than 100 years is entirely possible. We have no idea. The real argument is whether or not global warming is man made and whether or not global warming is a naturally occurring cycle of the earth. I for one believe the cycle of the earth is larger than we know and it is natures way of balancing things out. Throughout history, humans have a way of thinking the earth revolves around them. As history shows, we once thought the world was flat, because we couldn't comprehend that it would be anything different than our minds could fathom. Is it possible we could be off base here in our assessment of global warming? The earth wasn't flat after all....
