There may not even be a trade-off here. If we (reasonably) consider that the “End of the World” represents infinite cost, then even a very small risk is not worth taking because
small_risk * <infinity> = <infinity>. If there is any 'significant' risk that CO2 will cause the End of the World, and there is an action we could adopt to stop or slow it, we owe it to our children to engage on that, irrespective of cost (yes, nothing is irrespective of cost, please cut me some slack here; Oscar has hurt my feelings). Otherwise, the correspondent in
Orbserver's quote is right to say
we all know that carbon emissions are contributing to global warming and ecocide. But do we use our cars less for pointless journeys? Do we even eschew petrol-intensive four-wheel-drives for sane cars? No; it's me, me, me, baby, and - hey! - I hear that global warming is all a myth anyway.

Kerry should get in, but not because he might be green, and Tony should get the chop as well as Bush because they have made petrol dearer
Well, Kerry appears to be both smarter and less big business oriented than Dubya, so it might be possible to convince him by the weight of evidence that backs the “End of the World” hypothesis. Pete317 scorns scientific consensus as ineffective, but gives us no clue as to how decisions should be otherwise made. As for Tony, he has lost contact with reality, I'm afraid, and we need to get him out of the job for the sake of mercy. Although he is making a damn good job of these scameras! I can't really condemn them for the gas price though, much as I'd like to. It may be possible to pin something on them with hindsight, but that's always 20:00.

You know about satellites, so you should know about this
I'm not sure what you mean by the 'surface record'. Give me a URL so that I can check this. How are these measurements made? Indeed, I didn't know we had temperature data from space. I can only assume someone is using a geostationary weather satellite in some way, or is it a low earth orbiter with some instruments to measure radiation? If so, this is rather remote (36,000 km for a GEO and ~ 300 km for a LEO) and maybe indirect and inaccurate. I really can't say. I was involved with TVSAT1 and 2, DFS 1, 2 and 3, IRS1A, IRS1B, and IRS1C, and RADARSAT. Most of them were Geos related to TV pictures, although IRS1A was Geographic and RADARSAT carried a Sythentic Aperture Radar. This was used to scan the whole Antarctic Continent for the first time ever in September 1997. I planned the passes. The Byrd Polar Institute coordinated the project, and the guys seemed concerned about melt-off even then, although a planned follow up mission to gauge the exact rate cannot be scheduled until Radarsat II is operational.
What I can say is that a low earth orbiting satellite takes about 100 minutes per rev right around the planet, which is somewhat less than a soccer match if you include half time. When you do a pass in the control room, it takes around 45 minutes including pre-pass checks and data processing. By the time you have a cup of tea and a fag, and done a bit of fiddling with the command console, it's time to set up for the next pass. It does bring home to you how tiny the planet is, and its atmosphere (which is a smear of gas on the surface) is so very fine. As for David Bellamy, I can only say that he is a popular Sci-lebrity who may or may not have any relevance. Is he any good? I seem to recall some controversy he stirred up in Tasmania - what's the guff on that? Has someone got to him?

It was like this before in history, so what is the problem?
Yes, but in history, we didn't have a population of 6 to 10 billion. Nor did we have industrial expansion blasting out 6 billion tons per year of CO2 into the air. Nature seems to have controlled the climate within bounds recently, but now there are credible theories that the current period of stability could end abruptly if the Gulf Stream conveyor quits. As
small_risk * <infinity> = <infinity>, we should try to play it safe if we can, but I fear it has gone to long. As for the idea that past CO2 increases occurred after global temperature rise, fine. But this time the CO2 increases are occurring before it, so says the ‘scientific consensus’. Our capacity to use past performance to predict the future is diminished, due to our much-changed circumstances. Given the global rise in sea water temperature evidenced by coral reef bleaching, and the gradual erosion of island communities in the pacific and other places, it is becoming increasingly evident to many that the warming is a real effect of CO2. The fact that personal experiences and the recent hot summers corroborate this gives it further weight. In any case, even if, as you put it, the Nay Sayers are right, we can only defer the cuts in CO2 output due to oil burning for as long as the oil lasts. As you know, OPEC is at peak production, the North Sea is on the wane. Why put off the inevitable when it is risking the future or the world. The downside is huge. Yes, I know they said in the ‘70s the oil would be gone by now – I actually wish it was, because we would be compelled to finance better alternatives.

But some glaciers are advancing, you know
It is the weight of all evidence that makes the case for global worming (sorry warming) so compelling. I understand why you might want to test the data in this area, but I cannot believe that, at least in part, you have doubts. It is the pure number of events that have come together in recent times. It is my greatest wish that these dire predictions are false, but we have to hope for the best
and prepare for the worst. As for local pollution, that is not important to me (selfish as ever). In fact, I would be happier if the pollution that is created in London and other cities could be confined there! Having said that, it is possible that I could end up in one of those fleshpots again at one point, having lived in big cities before. So in principle, I like the idea of switching to estuarial, tidal, wind, wave, geothermal (the big constant one) and nuclear (the other big constant one) to give us unlimited quantities of emission free power. New cars do omit progressively slightly less CO2 (and much less other stuff) than older ones, although some studies suggest that more CO2 is created in the production of 1 new car than it ever uses in it's time on the road, so this suggests it is better to encourage the maintenance of older cars.

If it works, it's obsolete.

That could spell the end of cameras, and average speed monitoring between points would be the way it could be done, if we haven’t all been drowned by the rising sea level! However, I am loath to wax lyrical on this as much as I normally would due in case anyone has a funny turn and comes after me again.
