This is for both sides of the argument! (by the way, that NOTJFV has become number 43 on my list LOL)
I am a middle of the road kind of guy on GW, however look at all of the bold words below, and this was just one event today with one person.
Yes we should invest in alternate forms of power, but we have not come up with any that can give us what what we currently use. Until that time comes, I am glad to be living in a time when we have all of theses comforts.
I just got done with breakfast!
1. I had 3 eggs which were brought to the store with a Semi-truck, which I cooked with Electricity
2. I had two slices of bread in which the wheat was harvested using a Tractor,which was brought to the bakery with a Semi-truck, which baked the bread using an Electric oven, which was then cut and bagged using Electricity , which was then brought to the store with a Semi-truck
3. I also had some brown and serve sausage which was made from a pig that ate grain that was harvested with a Tractor. The pig was slaughtered and processed, using Electricity, the sausage was cooked (maybe using natural gas), then it was frozen using a freezer which by the way uses Electricity, Then it was packaged using Electricity, and transported to the store with a Semi-truck. Which I heated in the microwave with electricity
4. I also had a glass of milk that came from a cow,that ate grain that was harvested with a Tractor. The milk was pumped out of the cows using electricity, which was then pasteurized using electricity, then packaged using electricity, then kept cold using electricity and finally brought to the store with a Semi-truck
5. I used my car which uses gas to go to the store to get all of the items after I used my car to back and forth to work, so that I would have money to by food and pay for the energy that I am using
PS I am sitting in an air conditioned office using a computer with light while charging my cell phone and listening to the police scanner while sipping a hot cup of coffee --- All of these items also require (d) Oil, gas, electricity just for little old me.

I am skeptical of the IPCC's position on anthropogenic global warming. I do believe that there has been an overall warming trend over the last century. I also believe that CO2 emissions have significantly contributed to an increase in atmospheric CO2, which in turn is responsible for a portion of the last century's observed warming. That is about as far as I can go on the pro-AGW side of the argument. Below is a quick list of points that further define my AGW views:
1. While I believe that warming has occurred over the last century, I think it is uncertain exactly how much. I think the historical temperature record is subject to significant errors.
2. I am not convinced that recent warming is unusual or unprecedented. I think that proxies used to estimate past temperatures are subject to significant uncertainties.
3. I don't think that natural causes for the warming of the last century have been sufficiently ruled out. Variations in cloud cover as a contributor to warming remains one possibility. The PDO also seems to correlate well with warming/cooling periods over the last century (this may be related to variations in cloud cover as well). Note that this is not intended to be an all-inclusive list by any means.
4. I think that the IPCC climate projections for the year 2100 are likely overestimated due to feedbacks assumed in the climate models used that have not been adequately observed in real life. That is not to say that feedbacks in the climate system do not exist, but I believe that our understanding of them is insufficient.
5. I also believe that the doom and gloom scenarios resulting from the IPCC's predicted temperature increases are highly uncertain.
Whew! This is getting too long so I'll truncate it here. In closing, I would like to add that I have no problem with alternative fuels. In particular, I think solar power shows some promise in some applications. I don't think the switch to alternative fuels needs to occur before they are economically viable. I think that a switch to alternative fuels will occur gradually primarily due technological advances that make them more viable as well as demand/supply issues that will eventually increase the cost of fossil fuels.
Sorry for such a long post. It will be interesting to see if any discussion occurs that rises above the typical "The debate is over and everyone who says otherwise is not credible" variety.
