The earth has always had periods of warming and cooling, and it is my understanding that over the last 160,000 years the earth has mainly been under the control of ice except for two warming periods known as the Eemian Interglacial and the Present Interglacial. These larger cycles can be broken into periods of short cycles lasting around 400 years and then broken down to 40 years period. We see this in recent history with the Medieval Warming period and the Little Ice Age (400 year cycle example). Our current broad cycle, the Present Interglacial is about 18000 years into it so we can estimate that at sometime in the next 2000 years our planet should cool and possibly enter a new Ice Age. So in my own opinion I believe we are seeing a period of warming and that at some point we will see (or our descendants will see) a cooling period. Bottom line, the climate of this planet changes for a variety of reasons (humans being a very small percentage of that) and we need to be aware that of its own accord it changes and we should be ready to adapt to those changes. I like this quote the best: "Since the climate has always been changing and will likely continue of its own accord to change in the future, instead of crippling the U.S. economy in order to achieve small reductions in global warming effects due to manmade additions to atmospheric carbon dioxide, our resources may be better spent making preparations to adapt to global cooling and global warming, and the inevitable consequences of fluctuating ocean levels, temperatures, and precipitation that accompany climatic change."

I'm just guessing but is it possible that it may be melting because of some kind of cycle?

Finally, the article that proves it is all a hoax. I guess the question remains why is the ice melting?
My understanding from past list administrator statements is that this kind
of post is "okay" here.

Hacked emails from the Climatic Research Unit (Britain's University of East Anglia) appear to implicate leading climatologists with scientific fraud.
