JA I've been preoccupied with making arrangements to view a DVD from Philip M 'The Global Warming Swindle'. Herewith the three comments you made to my last post Peer review of unproven, unprovable supposition by supporters of the same worldview are meaningless to truth seeking. So much science has nothing to do with testable-repeatable stuff but with interpreting things so they fitt the world-view. And that boils it down to faith. How then would you organise so as to discover truth? For that matter, how would you recognise truth? When a fact is taken and interpreted according to a world-view and then the interpretation is presented as fact, you are not engaged in "scientific practice" you are engaged in "trust in what other people say with no evidence". The problem is, that if your world-views match, than it would be extremley hard to recognize the difference. I'm sorry -- I can't get the gyst of what you are saying here. [1] This is where I want to hear the evidence that makes it "undeniable" that mans activity is additive and [2] the additive amount equals massive trouble that requires action. [3] You are still dismissing the possiblity that the sun is solely responsible for any meaningfull change in global temperatures. I've broken this into three parts. First. If you create two boxes from plywood, one metre in all directions, paint them black and put them in the sun with temperature sensing probes inserted, then after some time you will note that the temperature will have risen equally in each box, more or less stabilising after some time. Later in the day as the Sun passes the zenith and sinks toward the horizon, the indicated temperatures will be found to fall, also equally. If tomorrow you repeat the experiment but with a lighted candle in one box, you will note that the temperatures will again track, but the one with the candle in it will be marginally higher. Second. This is not certain. I have not claimed that it is. But I have claimed that it is prudent to consider the possibility that it is. I still so claim. Third. Yes -- because, as explained above, you could only claim this to be so if you took Man and his activities out of the equasion. I note however your use of 'meaningful'. My comment ignores this. From an earlier post From Paul Deema Sat Jun 16 23:11:59 2007-- (you in red). You could start with facts - but be ready to be challenged on whether you've actually given a fact or simply an interpretation based on a worldview. A body, wholly or partially immersed in a fluid experiences an up thrust equal to the weight of the fluid displaced. Testable in any suburban kitchen. When rolling down an incline at a given angle, all spheres will out accelerate all disks which will out accelerate all hoops. A bit harder but you should be able to test this in your garage. A syphon will transfer liquids from one vessel to another only while the height of the surface in the source vessel remains greater than the height of the surface in the destination vessel. Testable in any suburban laundry. And here's a beauty! We've all seen the experiment where a lighted candle placed in a bowl of water is covered by an inverted cylindrical glass jar whose rim is pushed down below the surface of the water. What happens initially is that the water in the jar is pushed down below the level of the surface in the bowl but that presently the candle extinguishes and shortly after, the water rises in the jar about 20% of the height and we are told that this demonstrates that the oxygen content of the air is about 20% by volume since it was used up by the combustion. Well this is wrong. I have done an experiment which shows that this is wrong. Further I have deduced why the explanation is wrong. To this date (30 years have elapsed) I have not received a summons to answer charges of scientific heresy. I look forward to your comments on these four examples I gave you four examples. I'm still looking forward to your comments.
