Erik, Water is a major problem with current techniques for oil shale production, but if in-situ methods can be used and much of the water recycled, than it may not be as much of a problem. I certainly would want any oil shale production to be done in the most environmentally friendly way possible. It is something that deserves careful and reasonable consideration since we have potential recoverable oil shale reserves in Colorado, Utah and Wyoming of over one trillion barrels - more than the total Middle East conventional reserves. "Still the question remains what would have happened in middle ages if man was putting the gases in the air we are today. Would man have been adversely affected if our population numbers of today existed then." I don't know. But I think we need an open and complete debate about the causes and mechanisms of climate change. In Monday's Wall Street Journal they interviewed many prominent people about global warming including Al Gore on one side and Vaclav Klaus, President of the Czech Republic on the other. Klaus, who was trained as an economist, stated: " As a person who spent almost 50 years of his life in a communist country, I know how crazy it is to introduce schemes like cap and trade and similar ideas, how devastating and damaging for the economy all those ideas really are." And "I am afraid that a serious debate about the issue (global warming) has not yet started. What we are witnessing are monologues, a conference of believers in (manmade) global warming. The debate has not yet started. Nevertheless, I'm afraid the politicians have already accepted the idea, understood that it's a good political project, and now things are moving in a way which I consider extremely dangerous. He then adds, " But I would like to make one thing clear, lets really differentiate the protection of the environment from the debate about global warming and decarbonizing the economy. I am not against the protection of the environment. I am against global-warming alarmism. Those are conceptually, structurally, two totally different issues."... "To win an argument you must have a potential place to argue, but I am afraid that does not exist anymore. And to speak of scientific consensus about global warming, it's not true. To speak about a very strong relationship between carbon dioxide and the temperature in the world, again, not true. And I am really frustrated, I must say." The proposals to reduce greenhouse gas emissions will hurt the poor the most as Roy Inniss, National Chairman, Congress of Racial Equality (CORE), has been proclaiming. Lower energy costs correlate with people getting out of poverty worldwide, while high energy cost force many into poverty and even starvation. The cap and trade proposals will substantially drive up energy prices worldwide. Let's have a real debate about the causes of climate change before spending trillions to fight a problem that may not exist.

Don,
I looked at both you links thanks. I have not seen what they think the cause of the Middle Ages warming was. The graph did appear to be slanting upward, it will be interesting to see what happens in next five years. If it ticks up again it seems that will indicate gradual warming. Not using tree-ring data does seem valid but it does not contain much data of upper atmosphere vs lower atmospheric temperatures. Still the question remains what would have happened in middle ages if man was putting the gases in the air we are today. Would man have been adversely affected if our population numbers of today existed then. It seems premature to claim man can't effect it. IE: Increasing Greenhouse Gases unchecked for next 50 years. If extreme warming can occur period (with or without mans influence), shouldn't we a least plan for the future? Some of what Plan B calls for. I am interested in your opinion on Oil Shale. Can it be practical to produce a lot of Oil? or: Do the water demands dictate that it can be developed only on a very limited basis? Erik See
