Here is my take:
1. It is a natural cycle. The earth warms until ice-caps break off into the ocean. This cools the currents, which effects the weather, which reacts to bring the temp down. The ice-caps begin to grow again in size, and as such the weather stabilizes, and soon (geologically speaking) the weather warms, the ice drops, rince...repeat...
2. It is our responsibility to help the natural cycle remain natural. We don't really have to go to extremes, but at the same time we don't have to waste and pollute excessively either.
3. Every issue is political to someone, and to those people, there is money/power to be had, so they will push it. Can't stop it, but I for one will not be a part of it if I can help it.
4. I too believe that there will be a spiritual based end to the world long before we can destroy it ourself. That is my personal belief. Scientists are great at explaining the "how" of things, but I really need a "why", which science can't explain to me.
5 For everything else, there is Mastercard...
