Global Warming and CO2 levels
(Highly relevant to anti 4x4 lobby !!!)
Interesting documentry on channel 4 tonight about global warming. It seems that there is very strong evidence that although CO2 levels historically have been high when the earth warms up, the level of CO2 LAGS the temperature rise so isn't the cause, but a symptom. However there is historically excellent evidence that earth temperature follows sun activity. The stronger the sun activity the stronger it's magnetic field, and the more cosmic rays are deflected away from earth. Apparently the cosmic rays entering a water laden atmosphere form clouds which reflect the sun, so when the cosmic rays are at a low, so is the cloud cover and up the temperature goes. After a considerable lag the ocean temperature rises a bit, and as CO2 is less soluble in warm water than cold water, more is released into the atmosphere. Apparently the volume of CO2 dissolved in the oceans and naturally being released is orders of magnitude greater than anything man is releasing. Small changes in sea temperature alter the balance.

So, the antis were right all along and can now go back to destroying the Earth's atmosphere with a clear conscience? You mean doing things like eating? The IPCC report rated agriculture as the predominant source of methane and nitrous oxide and a significant source of CO2. They are not even sure that human intevention has anything to do with the changes, which the data from Mars suggests would happen anyway. The IPCC assessment of human intervention being responsible for various climate changes ranges from 'likely' - warmer and fewer cold days and nights over land / warmer and more frequent hot nights over land - to, for most, 'more likely than not', which means there is a high level of uncertainty. Last night's programme was as biased and one-sided as all the pro-GW programmes which went before it.

I've yet to meet someone who has had a real change of mind. I have not decided on the subject, but I have yet to see anything to convince me that changing the way we live, particularly in Britain, is going to make any difference. If we seriously want to reduce CO2 emissions, which it is far from proven will help, it would be far more effective to help third world countries achieve the same reductions we have made over the past decades. However, that is not a very visible way of doing it and therefore is not going to get a UK politician many votes. We need some *balanced* programmes with both sides represented. The IPCC report is about as balanced a view as you can get. Chapters 2 and 3 should make interesting reading when they are published. Colin Bignell |

Since all the surface conditions on this planet are directly associated with the interaction between its atmosphere and solar radiation, this should hardly be surprising, but it was. I was a little less happy with the suggestion of an 800-year lag in their claimed correlation between CO2 and temperature - no-one seemed to suggest which event in the middle ages might link to what we can observe now - but it did see to me that previous cycles of high temperature and high CO2 does rather weaken the argument that somehow we might be entering a "runaway" phase. The evidence from long-term trends was that increasing CO2 didn't apparently cause any acceleration in the warming phase. I can't follow the argument at all that says that we shouldn't tinker around with CO2 levels because we don't know how sensitive the "system" might be. Human contributions to CO2 are small and if the system was sensitively balanced then you would have to argue that the remaining 90%+ was somehow naturally invariant, and once you have added in the much much larger "greenhouse gas" effect of water vapour, this doesn't hold much weight really. A risk might be that we have managed to remove a moderating factor, and the loss of vegetation over the tropical regions is certainly of concern, not to say wasteful, but the chances are that the primary moderator of temperature and water vapour concentration and CO2 is the world's oceans.

Especially the evidence that shows tempreture rises preceed the increase in CO2. Its the greens that use the same evidence to prove CO2 causes global warming that are biased. The theory of global warming stands or falls by the effect of CO2 in the atmosphere, not by the source of the CO2. That the CO2 released by the oceans lags the increased radiation from the Sun is only to be expected. It says nothing at all about the other sources of CO2 or about the effect of CO2 on global temperature. -- Roger Chapman |

It is accepted that CO2 isn't a particularly powerful greenhouse gas.. but it is the only one *we* can control. Just how much control we have is the real question. It says nothing at all about the other sources of CO2 or about the effect of CO2 on global temperature. If it says nothing about the effect of CO2 on global temperature.. why all the fuss? |

Apparently the cosmic rays entering a water laden atmosphere form clouds which reflect the sun, so when the cosmic rays are at a low, so is the cloud cover and up the temperature goes. After a considerable lag the ocean temperature rises a bit, and as CO2 is less soluble in warm water than cold water, more is released into the atmosphere. Apparently the volume of CO2 dissolved in the oceans and naturally being released is orders of magnitude greater than anything man is releasing. Small changes in sea temperature alter the balance.

We could be aiming to do that on a global - indeed extra-global level (and maybe even aiming to protect 100% of the population). Or we could sit around squabbling while it all happens. Perhaps it's time for a B-Ark :-) [1] typical lawyer/politician knee-jerk response: "who's to blame?" [2] with the possible exception of some religious nutters who'd say it was the Sky Fairy's will and we should sit back and take it up the botty. |

(Highly relevant to anti 4x4 lobby !!!) Interesting documentry on channel 4 tonight about global warming. It seems that there is very strong evidence that although CO2 levels historically have been high when the earth warms up, the level of CO2 LAGS the temperature rise so isn't the cause, but a symptom. However there is historically excellent evidence that earth temperature follows sun activity. The stronger the sun activity the stronger it's magnetic field, and the more cosmic rays are deflected away from earth. Apparently the cosmic rays entering a water laden atmosphere form clouds which reflect the sun, so when the cosmic rays are at a low, so is the cloud cover and up the temperature goes. After a considerable lag the ocean temperature rises a bit, and as CO2 is less soluble in warm water than cold water, more is released into the atmosphere. Apparently the volume of CO2 dissolved in the oceans and naturally being released is orders of magnitude greater than anything man is releasing. Small changes in sea temperature alter the balance.

It's all true, but against the flow (until temperatures begin to fall) Quite. If one simply enters "carl wunsch" as search terms in Google, there are a slew of articles in publications ranging from the Economist to the Royal Society where he has said essentially the same things, so it isn't as though what he said in the C4 program was new for him. Then one asks the obvious question of surely he saw the program before it went out. Now he is complaining *after* it went out, one can only assume that he has been leaned on in some way or decided that he doesn't want to be marginalised. It's disappointing, but I suppose not surprising when science becomes so heavily influenced by populism rather than its core business. -- ..andy |

Global Warming and CO2 levels
Sorry missed out the quote: http://entertainment.iafrica.com/tel...ion/671607.htm TASHI'S TV 'The Great Global Warming Swindle' Tashi Tagg Fri, 09 Mar 2007 A juicy new documentary called The Great Global Warming Swindle has just been broadcast (on 8 March, 2007) on the UK's Channel 4. Based on the thesis presented in the book The Chilling Star by Danish scientist Henrik Svensmark, the documentary claims that humans have absolutely no control over Global Warming and that all the hype about it is simply propoganda inspired by the huge amounts of money given to what's become a popular cause. I caught an interview with one of the scientists involved with it on CNN on Thursday night and everything he had to say made total sense. The argument the scientists are making is that the sun impacts on clouds and clouds impact on how the suns rays get distributed, which results in changes to the earths temperature. They're saying that carbon dioxide omissions have a miniscule, if any, impact on this process and that it's proven by the fact that most Global Warming took place prior to 1940 - before people started pumping out CO2 gasses. The mouldy oldy Einstein dude being interviewed (I can't remember his name) said that huge amunts of information gets kept from the public about what's actually happening with the earth and used Antarctica as an example. He referred to all the media reports about the icecaps melting and the pictures they show etc and said that these are simply around the edges of Antarctica and that at it's core it's actually getting colder. He also said that something we're never told is that the earth's global temperature has remained constant for the past five years. When asked why we'd be misled like this he said that the scientific studies into the impact of CO2 gasses on the climate started in the 1980's and had tons of cash injected into it. For such an investigation to get more money they obviously need to make dramatic discoveries to justify why more cash needs to spent on further studies and action, so the more hype and fuss they could make about people's responsibility, the more cash everyone's been prepared to spend. To me it really sounds like it's the truth. In a climate that's so socially aware with people so keen to show how much they care while blaming everyone for everything it makes sense that tons of cash can be made by appealing to people's sense of guilt. Also, he mentioned that scientists who didn't support the theory were constantly at threat of having their funding pulled. That's the way money operates all the time so it gives the argument further credibility. The trouble is - will anyone want to back down on madly Going Green now that everyone's made such a big deal about it? As we speak there's some big summit about Global Warning featuring all the worlds leaders discussing solutions and looking special. I just don't see them suffering the embarassment of suddenly saying that it's all been a scam and that we're simply at the earth's mercy. On the other hand they can't just ignore it and carry on wasting people's taxes. Apparently the documentary also looks at the impact the whole trend has on poorer nations who are being told to spend money and do stuff that's hindering them instead of helping. Let's hope we get to see the show soooon. It's sounds like a very plausible theory don't you think? -- Jim S Tyneside UK http://www.jimscott.co.uk |
