Its the World Met office thats gone wonky not the weather ! Evidence? Apparently there are plans to cut their budget so they feel the need to cobble together some ******** to justify their existence Evidence? -DESMODUS Sadly, nothing at all justifies your existence. |

Let's also keep what the WMO had to say in some kind of perspective, shall we? A heat-wave in India that had a high mortality rate? How is that different from the heat-wave last year there? Or the year before? Or the year before? Something that happens every year can hardly be called unprecedented, now can it. More life-saving air-conditioners for India, and nuclear plants to run 'em, sez I! -dl |

I'll ask the question again: have you seen some scholarship that proves a definitive link between the tornado outbreaks in May in the US and climate change? If so, please provide a citation. What you are doing would be akin to noticing that when the sun goes down, local temperatures typically start to fall. In your science, that's all you need: an observation. After that, you can make up what the cause is as you go along. It could be the loss of insolation or it could be an amazing show of will-power from your Aunt Molly's pet sheep, Henrietta. Sorry, but the science I learned was a wee bit more involved. Data requires careful analysis. One does not leap from data to conclusion without taking the necessary steps in between to make sure that the conclusions are correct. The WMO press release makes note of the extreme weather around the world, but makes no conclusions other than that it could have climate change footprint. Given the state of the science that is entirely appropriate. What the media have done with it, and what you are attempting to do with it, is inappropriate. It is not supported by the current science. You and others who write like you are setting up straw men. It is not possible to show "cause and effect" as if weather were a simple laboratory experiment.

I don't know where you got your PhD or what discipline it is in, but clearly you skipped the part about having evidence and taking a proper systematic approach to dealing with it. I can also make the distinction between a press release and a legitimate study. |

It is not possible to show "cause and effect" as if weather were a simple laboratory experiment. There are none so blind as those who will not see. This is, to some degree true. Because of the multivariate and semi-chaotic nature of weather and climate it is very hard to find causal factors. We may never have an adequate causal mechanism, and yet we CAN do modelling studies which illuminate that the link IS present. Kind of touchy feely but it can amount to proof with enough studies. Kind of like mathematical proofs provided by exhaustive testing of all possibilities. You see it, you acknowledge it, and a half hour later you are hungry for more. Just not satisfying. |

The only value of annecdotal evidence is to prompt a search for the mechanism by suggesting hypothetical links. It is bad enough have David spouting that BALLocks, without you parroting it as well! It is not ********. It is a principle on which science is based. I learned it in university. It is not my fault that you apparently failed to learn the basics. The scientific method is to produce hypotheses, No. The scientific method is to observe the world, and note patterns(correlations). Then produce hypothesis(mechanisms) that might explain these patterns or correlations, and seek to prove the mechanism. The mechaniism will usually have other effects secondary to the observed ones and the finding of these secondary effects can be strong evidence that the mechanism is in fact in operation, expecially if no other mechanism would produce similar results. then to devise experiments with which to test them. Science does not demand experiments. Only observation. Sometimes there is no way to experiment. In other cases the equivalent to an experiment is observed ( such as the temperature drop following a volcanic eruption ) that are impossilbe for man to generate. If the tests are met, then the theory is upheld. Or if the hypothesised mechanism can make a prediction that can be observed. In this case the hypothesis is that if we add CO2 to the atmosphere, global temperature will rise. Assumption. Global average temperatures, both in time ( one year ) and in space ( over the planet ). Record temperatures are being recorded throughout the world. Record temperatures are peak and nothing in global warming makes predictions that the peak values will increase. In fact, since the global warming must be averaged over all the planet, nothing in regional extremes is connected to the global warming theory. You would have to introduce another theory tying increases in global average temperatures to local regional extremes. Therefore the theory that CO2 causes global warming is upheld. Rather, the measurement of the global average temperature and it's rise shows that global warming is occuring. The local extrema are not relevant and prove nothing. Note I did not say proved, because you cannot prove any theory. I have no objection to the normal usage of 'proof' as the dominant consensus of the experts in the field. David's claim that higher temperatures don't prove global warming, is just a straw man! No. Higher peak temperatures do not prove global warming. Higher global average temperatures, after dissecting their causal mechanisms ( solar, aerosol, and ghgs) do prove global warming. No one is saying they prove the theory. We are saying they uphold the theory, which they DO! They neither deny nor uphold the global warming theory. It does not predict peak values or regional climate. Note also the fundamental point that meteorology and especially climatology are not experimental sciences in the true sense. As noted, science does not demand experiment. We cannot raise CO2 levels and keep everything else constant, to measure the effect of CO2. Any earth scientist knows that. You are taught it in the first lesson of the first year at college. And yet their is a science of meteorology, etc. Therefore science is not exclusively by expeirement. One can merely observe as the system changes and deduce the mechanisms of that change. This is very much the way that many such fields work such as particle physics and astronomy. David may be a qualified meteorologist, but that mean it is impossible for him to get simple facts like that wrong. It is just that it is impossible to get him to admit it! Why would he admit that you are wrong? Try getting a clue Alistaire. You are making way too many mistakes in your arguments here. I appeal to you Ian, to look and see just what David is doing. I do. I agreee with him that there is no causal connection provable. At least not yet. I posted a message saying that the North West Passage would be open this summer. He changed that thread into an argument about the difference between association and correlation. How is that going to add even one ice floe to the NWP? His agruments are complete non sequiturs. Not really . I was going to post a correction to it to note that correlation is association but association is not necessarily correlation but held off figuring you were having too many points demolished as it is. David is correct in that regional climate change, and local meterology is the dominant 'cause' of weather and weather extremes. He is just a charlatan with a very loud voice. Surely you can see that? The fact that he always gets the last word is purely because he never gives up or has the wit to see he is wrong. I gather you looked in a mirror to generate this paragraph? The description is of you. However, between the two of your David is more correct in terms of science. This does not mean that we should not view such conditions as warning in terms that unusual conditions are increasing and this may indicate a basis such as GW. What it means is that you cannot say you can PROVE that the conditon is due to global warming. And he seems to have more time to waste here than anyone else. Since he is paid by the Canadian taxpayer, I would have thought that might concern you too! Anyway I have wasted enough time composing this reply. Way too much time as it says nothing you have not tried to claim before. To make your case you must uncomver and be prepared to describe the causal links. Cheers, Alastair. |

Not that it is a scientific work or has any point or merit that I might consider useful. The plain fact that it is from the UN is a big enough blot to render it valuless. Did it say anything about the monstrous way that agriculture has changed the way the weather behaves or about the way our rivers are controlled? Not that I am interested it's just that for reasons best known to themselves global warmers seem to think that the sun gets hotter without our knowing it. Or is that just my uneducated, hidebound, misanthropic pessimism showing through my carefully guarded herbacious borders? |

Idiot. Science is building testable theories upon observations.
Observations can come from many sources, and tests can also come from many sources. "David Ball" wrote in message ... On 05 Jul 2003 02:30:25 GMT, "Claire W.
