"John Rowland" wrote in message ... You sound like a knowledgeable bloke, but if global warming is hokum, why does New Scientist tell me it's real? Is this to do with research grants, like the asteroids heading towards the Earth that the astronomers find whenever they are trying to get increases in funding? Global warming is real, but it's a natural phenomenon, not man-made. Maybe it is , maybe it isn't. But do you care to explain why most climate experts (which I'm guessing you're not) have a different point of view? Or are they all part of some conspiracy or just plain deluded? Also I'd love for people like you to explain how its ok to accept as a fact that the CO2 in the air keeps the planet warmer than it would otherwise be but when the CO2 percentage rises , well , that won't make any difference. Right? Presumably because CO2 has some kind of magical thermal cutoff limit that means it won't cause anymore warming beyond a certain point no matter how much of it there is. Right? And the temperature on venus (which has a 99% CO2 atmosphere) is just a one off fluke. Right? B2003 |

"Global warming is real, but it's a natural phenomenon, not man-made." (You) "While the curves do not match perfectly at any time, they start to diverge noticeably by the 1980's. We interpret this widening gap as evidence for an additional influence on the temperature - over and above what the Sun is causing. We think this is likely to be due to the anthropogenic greenhouse effect" (Your ref above) So now I am confused. What do you in fact believe? What you said above? Or what your reference said? John |

Did you look at the first graph on the page, and read what it says about it? They don't know why there is a recent divergence. They are postulating.

Did you look at the first graph on the page, and read what it says about it? I looked at both graphs and the accompanying story, a few months ago in the New Scientist, and again yesterday. Neither supports what you are trying to make it support. They don't know why there is a recent divergence. They are postulating. Man-made additions to the CO2 in the atmosphere did not suddenly start in the 1980s. Indeed not. If the scientific mainstream (say 9 out of 10 scientists who study this kind of thing for a living), and also the article *you* chose to highlight your argument, both disagree with you, please do tell why your opinion is nonetheless right.

CO2 is only one of the infra-red absorbing gases in the atmosphere. Methane CH4 is another and is a stronger absorber than CO2, but the most abundant and most effective is water vapour. Even moreso when it condenses into clouds. Waters influence on climate varies depending on where it is and what state its in eg stratosphere or troposhere , ice crystals or droplets. CO2s influence is contstant. As for methane it reacts with O2 fairly quickly and is converted into C02 so its long term impact on climate is not that important. There is a natural CO2 cycle, which involves its conversion by vegetation into Oxygen and organic material, by photosynthesis. The more CO2 there is in the atmosphere, the more this reaction can proceed. The CO2 also It may well speed up but not necessarily at the same rate and this is obvious given that C02 levels are rising. PLus man cutting down whole swathes of vegetation that could mop up this extra CO2 doesn't help. dissolves in water falling as rain, as a further part of this cycle, and some will be absorbed by the oceans, in turn to be taken up by shellfish to help make their shells. It's all to do with reaction equilibrium. Have a look at http://www.metoffice.com/research/ha...cle/index.html for more information. Venus is irrelevant in this context. Really? I think its highly relevant in that it shows exactly what could happen if a gunaway greenhouse effect takes hold. Our only saving grace is that we're 50% further from the sun than venus so if it ever took hold here the temperature might only rise to 500K instead of 750K. B2003 |

Do you know the history of the atmosphere of Venus? Or of Venus itself, for that matter? I know what I've read. The general consensus seems to be that billions of years ago it had large amounts of water but also large amounts of CO2. The CO2 heated the planet up beyond the boiling point of water despite the sun being weaker then and the rest is history. Anyway , this is getting way off topic. The point is more CO2 = more heat trapped. Thats simple physics and you cannot argue your way out of it. B2003 |
