That seems a bit unlikely to me. Surely the issue is how potent is the extra co2, is a slightly warmer world such a disastrous thing and how many other factors are driving the climate. Lets hypothesise that Co2 is not known to change climate but the world was either warming or cooling -who would be held to blame , would there be such a huge bandwagon and would there be the same hysteria. I doubt it very much. They global cooling scare of the seventies didn't catch fire so to speak, like AGW did why? Well I believe the difference was with global cooling the left had no one to blame but with AGW it was the perfect weapon with which to bash capitalism and boy oh boy has it done so. Utter idiot. |

This posting is quite surreal. You say you have a better insight into systems than the meteorologists. Meteorology involves more than just systems - physics for example. It's just possible that they have a better insight into meteorology than you - they ought to, with no disrespect. Pack this up - you're in danger of becoming a laughing stock.

One of the silliest responses I've ever seen. Cite them. Cite Lindzen (debunked) Miscolczi (debunked) and others. How on earth do you know they are "half way there"? It is unlikely that I will win the lottery tomorrow but someone will. In fact someone has just won £1,000,000 twice. So the fact that it is unlikely does not mean it is not possible. Absolutely not. It is also not impossible that the USA did not actually land on the moon and it is possible that the twin towers really were a CIA plot and Elvis lives, in his dotage, in Cleckheaton. You believe in things simply because they are not impossible?? But the people who are investigating the climate system are meteorologists, physicists and mathematicians. I am a retired system engineer so have a better insight into systems than them. You are joking.

You live in cloud cuckoo land. PS Tell us how cold radiation is a fact, despite the laws of thermodynamics telling you it is impossible. |

This is a good place to start to see what climate models the IPCC is using for it's reports. http://www.ipcc.ch/pdf/assessment-report/ar4/wg1/ar4-wg1-chapter8.pdf Plenty of detail about the models. Some are open source so you can download the model and source code and compile and run it for yourself. |

I tend to ignore the IPCC reports which I see as over 1000 pages of waffle. But I have read the FAQ which repeats the theme of the radio programs - the models don't work but we believe them because they are based on SCIENCE. FAQ 8.1 it says: "How Reliable Are the Models Used to Make Projections of Future Climate Change? There is considerable confidence that climate models provide credible quantitative estimates of future climate change, particularly at continental scales and above. This confidence comes from the foundation of the models in accepted physical principles and from their ability to reproduce observed features of current climate and past climate changes." Yet the models failed to predict the increase in Antarctic sea ice, and Jane Francis admitted that the models do not agree with her paleoclimate data. "Model global temperature projections made over the last two decades have also been in overall agreement with subsequent observations over that period (Chapter 1)." Oh yea? What about the hiatus? "Nevertheless, models still show significant errors." True. "Significant uncertainties, in particular, are associated with the representation of clouds, and in the resulting cloud responses to climate change. Consequently, models continue to display a substantial range of global temperature change in response to specified greenhouse gas forcing (see Chapter 10)." Aren't clouds rather fundamental? If I recall correctly in both radio programs it was emphasised that all scientists are sceptics. Anyone else here call themselves a scientist :-) |

There is, because the whole atmosphere radiates in the infrared. Yes, you are quite right. (Just testing you :-) What I should have written is that, like the radiation at the base of the atmosphere, the outgoing radiation at the top of the atmosphere is saturated.. So increasing the concentration of CO2 raise the height from which the radiation emitted. It is argued that since it is coming from a greater altitude in the troposphere it will be at a lower temperature and so decrease. But it will still also be made up of emissions from the stratosphere, mesosphere which will increase because the CO2 there is denser. Moreover, the CO2 band is already attenuated. Decreasing a small amount results in a small decrease. But that is not how it works. The clue is in your term "percolates down". The change in TOA OLR can be rectified if the TOA warms. There is no guarantee/mechanism to ensure the surface warms because the TOA cools. I don't think I have really answered your objection, but thanks for raising it. It is the weak point in my theory which I must address. |
