Point Of Order - a belief is not a fact! It is an opinion. You believe the ecology is going to pieces, requiring drastic immediate changes. I don't have the same belief. You undoubtably have facts that buttress your beliefs, as I do mine. Such facts can be discussed and compared, hopefully dispassionately, and might even change one or the other's beliefs, depending on whether the facts drive the beliefs or whether the beliefs drive the facts. But I can't accept changing the world, and causing tremendous damage to billions of lives, over an opinion. I don't have that right, nor do I believe you have that right. Even if I grant you beliefs (I don't, but I will accept them for the sake of discussion.), they don't all have the same timeline. Piles of trash will have a longer term degradation effect than, say global warming. It's not everything, all at once. I'll pitch some facts at global warming, as it's the hottest (pun intended) problem currently. Yep, we're pitching lots of CO2 in the atmosphere. And yes, its a greenhouse gas. These are facts. So are sunspots. Almost nobody talks about them. We're at a what we think is a peak of a peak of a cyclical peak in sunspots. Maybe we are, maybe we aren't. The future is a projection. But study the history of the "little ice age" in the 1600's. There were no sunspots for nearly a hundred years. Coincidence? Sunspots and global mean temperature track pretty well, as least as well as CO2 and temperature. We don't know the causality, just the correlation. Do you include sunspots in your global warming facts? How long will we be pitching CO2 in the atmosphere, at the current rate? All I see is straight-line projections for at least the next 50 years. I'm sorry, it's not going to happen, with or without command and control intervention. Why? Because the "invisible hand" of economic is going to change it. Personally, I like solar. I like using waste space (my roof) for economic gain. Right now it's too expensive. The price of crystaline silicon has gone from $5 a pound in 2000 to $50 a pound in 2007. Why? Too much demand from solar power and too little supplyof processed silicon. Lots of crystaline silicon plants coming on line in the next year or two. And that's not the CIGS technology trying to come on-line, or Cadmium Telluride that already on line (at half of silicon prices, building a new big plant every six months from the profits of the existing plants...) and a half a dozen technologies in the teething stages that may cut costs 10 fold in the next 10 years. The ramp up for conversion will be starting soon. Now it will take 20 years to complete, all big changeovers do, but the economics will become cost effective in 5 years. then it will be a matter of producing and installing enough product to make the changeover. What will happen to the CO2 curve then? Now these are opinions. But my opinions are just as valid as your opinions are. Because of my opinions, based on the facts and evaluations above, I see no need to panic and be overly concerned about global warming. I certainly don't see any need for draconian controls over it. Me, I'm planning to convert when the 20 year amortization shows a profit over the previous 5 year electricity average cost. I'm already saving my pennies. And that's not because I care a fig about global warming, but because I want to save money and get the CO2 whiners off my back! (The more money I save, the more polar bear hunts I can go on... ![]() Last edited by Greg Anos; 07-21-2008 at 09:54 AM. |

Intersting points, guys. Of course, people of my belief system (I always struggle with what word to use ... since Buddhism is not a "religion" in the true sense of that word) do not believe in a 'creator god." Although, we are also taught to believe that all faiths are worthy of the highest respect to the extent that they are based in compassion for others. Which is why I've always enjoyed discussing religion with people ... especially when it comes to the history and evolution of the belief structure. Someone here in Texas once asked me why there didn't seem to be any Buddhist "missionaries." I opined that it was probably because to try to change the faith of another person would be to cause them to suffer ... and the whole idea of Buddhism is to try to relieve suffering. Every person has to find their own path to enlightenment ... you can't force someone to have faith in something. And, requiring people to believe in something that is just plain wrong ... is just plain wrong. ![]() As the Dalai Lama said (and I'm seriously paraphrasing here so I won't use quotes ...) If modern science proves something to be false, then it is false. It doesn't matter if Buddha himself believed it to be true and stated that it is true ... it is still false. Buddha was enlightened, but he was still a human being, and as a human being capable of being wrong. |

I also like a bit I heard of from Chinese mythology, where the creation myth began with "First there was nothing. Then there was something, and the something was Pan Ku" The Hindi mythology has Mahasamatman, the dreamer, dreaming all the worlds, and that bit maps neatly the the concept that our universe is a bubble in a multi-dimensional hyper cosmos, where other bubbles also exist. A Hindu friend years back once told me that there were portions of the Hindu scriptures reserved for the advanced that talked about what happened when the dreamer woke up, but I never found out more about it. ______ Dennis |

Chairman Mao essentially became the Emperor. That wasn't what he called himself, but that was the position he effectively occupied. And despite supposedly being an egalitarian and classless society, there was still enormous concern, even among the Communists, with rank and precedence. Some years back, during the early stages of mainland China's push to industrialize and move to a capitalist economic model, a senior Chinese official was asked about the moves, and gave a remarkably pragmatic response. If it worked, it was a triumph of the glorious People's Revolution. If it didn't work, it was a product of the decadent Western imperialists. Use whatever worked, and change the name to make it politically acceptable... ______ Dennis |

Too many posts to comment on portions individually. I'll just add that there is something between "facts" and "opinions/beliefs" called "theory" or perhaps "hypothesis." We include all the best facts we can find in our working hypotheses, and adjust them as new facts come to light and are tested and validated. My current working hypothesis, based on my reading of scientific evidence, is that human-induced climate change is real and is a problem. (Yes, I've looked at the sunspot theory. I don't find it compelling, and neither do many other scientists who've also looked at the available evidence.) Regarding projections, no one can know the future, but one of the main goals of science is to attempt valid predictions. Models can be tested, validated, and improved. It makes sense to build the best models we can and to try to act appropriately based on their predictions, knowing that we may have to change the models as new facts come to light.
Meanwhile, we are left with the question of what actions to take now. I'm repeating myself, but given the obvious tendency most people have to base their decisions on personal costs, e.g. the cost of solar panels vs. the cost of purchased energy generated by coal or nuclear plants, if the long-term costs of generating power by various means are not passed on to the consumer, consumers will continue to make decisions with long-term detrimental effects for short-term reasons. None of the power generation vendors are going to be the first to include the costs of pollution mitigation and cleanup in their consumer prices, because that would create a competitive disadvantage in the marketplace. Again, this is where government regulation is appropriate. Of course, it's much more fun to rail on about how others are trying to deny one's personal liberties than to address whether government regulation should enforce the free market by requiring all costs to be included in a consumer commodity. ![]() The only other thing I'll add is that I've heard quite a large number of Muslims speaking out against the radical actions of the violent minority. They don't tend to get much air time in the U.S. They make the situation much more complex. A simple "news" story that plays up the role of the fanatics is more catchy and probably sells more advertising. ![]() |

Is that a reference to the Maunder Minimum?
There was some sunspot activity during that period. http://en.wikipedia.org/wiki/Maunder_minimum |

As for global warming, it think it's clear there is a warming trend. The question is the cause and what we may do to address it. My feeling is that we are are seeing the results of long term cycles over which we have little control. Human history and development begins in a time when the Earth was just coming out of a period of glaciation, and the trend was warmer. In prehistoric times when the dinosaurs roamed, there was a period when the entire Earth was tropical. Then things got cooler. While human activity certainly adds to the warming trend, it's doubtful it created it. At the time the glaciers began to retreat, there weren't human beings to do anything to cause or add to it. So the big questions are "How much is human activity affecting the trend?" and "How much impact can our efforts have in reducing or reversing it?" For the first, I don't know. For the second, I'm all in favor of efforts to reduce pollution and greenhouse gasses, simply on principle, but I don't see those efforts stopping or reversing the trend. The best I think we can hope for is to slow the rate of change, and give ourselves more time to adapt to the changes. Quote:
Whether the true costs of power generation get passed on tends to vary by locality. There are electrical utilities that are explicitly for-profit that do so, yet offer rates competitive with other utilities in the industry. Quote:
If you don't take it personally and feel it's all about you, it becomes easier to explore alternatives. But as mentioned up thread, once people have a worldview, the primary goal is to defend it. Suggestions that implicitly challenge that worldview will get nowhere. ______ Dennis |

Dennis, I see your point about the glaciers, though I think the current trend is more sharply defined than that. It's an area in which reasonable people can certainly disagree; since there are so many other problems associated with pollution that is generated along with the CO2, not to mention the geopolitical instabilities around fossil oil, I'd say we're better off to act now to look for better energy sources. It seems we may be in agreement there, in any case.
But then again, my willingness to accept ambiguity and try to see multiple sides of an argument may be another one of those unstated assumptions I absorbed from an early age-- my parents (particularly my mother) are much the same way. ![]() |

Actually, I follow C.P. Snow's falsifacation concept. Take all the fact you know on a particular item. Make a theory that covers all the facts. Then try to find facts that disprove the theory. When you do, make a new theory covering the old fact and the new facts. Repeat the cycle. You never find the absolute truth this way. You just narrow the range of answers the truth is in. But you don't allow yourself to fall in the logical trap of treating a false premise as a true premise that you can't/don't question... (Modern physics is probably in that kind of trap today. They have set certain things as constants, beyond question. If they are less than completely correct, then they're going down a blind alley, with no way out, because the guild doesn't allow the constants to be questioned....and then wonder why there hasn't been a new Einenstein in over a 100 years.) |
