This is a common denialist talking point. It glosses over the ‘inconvenient truth’ that warming due to increased CO2 (or other greenhouse gases) causes there to be more water vapor in the atmosphere, so water amplifies the effects of the other greenhouse gases.

None of the climate models could get anywhere close to realistic results about even the current climate if they did not take the effects of water vapor into account.

At some point, co2 effects do diminish, as you can only hold in all the heat. At that point added amounts don’t matter much.

The ultimate limit is demonstrated by the planet Venus, where the atmosphere is 90 times as thick as Earth’s, mostly CO2, and the surface is hot enough to melt lead. Earth won’t reach this state in the next billion years or so, and certainly won’t from the current bout of CO2 emission, but this does show the ultimate limits are not very hospitable.

I think it is a liberal conspiracy to take away my right to divine prosperity.

But anyways, as someone working in renewable energy in Nigeria, I found many of the assertions and arguments to ring particularly false to the reality on the ground. These four points in particular:

– “The polices being pushed to prevent global warming are having a disastrous effect on the world poorest people.” The only part of the Kyoto Protocol’s climate change policy that directly affects developing countries is the opportunity for partial sponsorship of clean energy projects in developing nations through carbon trading schemes such as the Clean Development Mechanism. CDM has been estimated to free up around $10 billion for clean energy projects in developing nations. The issue with CDM is that Africa is currently getting a meager share as governments like China and India’s were more able to organize to access this funding. I don’t think that’s quite the “disastrous effect” Paul Driessen alleges. Since there are no proposed policies that I’m aware of requiring Africans to limit their CO2 emissions, I’m not quite clear what policy he’s referring to…

– The implication that all renewable energy, particularly solar, is too expensive and inadequate. (via one improperly sized photovoltaic system!) The claim that renewable energy is three times more expensive than conventional grossly oversimplifies energy costs in Africa – where cost per unit energy can be many times that of North America. For instance, the convention in Nigeria is that anyone who can afford it buys a generator as a backup power source since the grid is only up about a third of the time. The office I’m working estimates they spent the equivalent of 10 bucks a day on fuel alone or about $50/week. Since we installed a $6000 solar system 2 months ago, we’ve only had to use the gen once (when the grid was off for a week straight). So our PV system will pay for itself in a little more than two years while most of the components (excluding the batteries) are supposed to last for 15-20 years. However, the majority of people don’t have that much cash to put up at the onset and interest rates are 18-30% here… assuming one could get a (very scarce) loan approved for something as uncommon as a PV system. So solar is too expensive much the same way buying a house is too expensive compare to renting – it actually can be cheaper in the long term but only if people can access loans. Granted, there are quite a few other issues with solar, but it’s deceptive to claim nobody in Africa can afford it.

– Africa is being told by climate change activists “Don’t touch your resources” Well yes, they’re right that Africa has oil. But no one, not even environmentalists, would or could argue that Africa shouldn’t benefit from it. Let’s just be practical about who is currently benefiting from those resources. In Nigeria, only one thousandth of the oil produced here is used by Nigerians. And the profits from the exports mainly go to the international oil companies and very rich politicians. The current climate change movement is not playing an even incremental role in keeping Africans from benefiting from their resources, especially compare to the (incredibly complex) economic and political systems that have evolved over the past two centuries. Please, let’s be realistic – if this is seriously a concern then climate change is the wrong scapegoat.

– Energy infrastructure in developing nations is being [though I’m assuming they meant ‘should be’ ] restricted to wind and solar as part of the global warming campaign. No one is actually advocating this. There are certainly people encouraging alternative energies to be included in a diverse energy mix and for very good reasons: Africa is still expanding its energy infrastructure which making both grid connected and decentralized alternative energy option cost-competitive in some situations. However, since these technologies aren’t as well-established they may not otherwise be considered. Diversification of non-fossil fuel energy also makes nations less vulnerable to fossil fuels’ unpredictable costs. Most developed nations planned their infrastructure in an era when fossil fuels were assumed to be endless and benign. Now they have a host of issues because of it. Shouldn’t developing countries learn from this and use it as an opportunity to develop better than the West? Due to the vastly different situations pertaining to North American and African electricity development the ‘We’re slow at adopting alternative energies and it’s even more difficult for them to’ line doesn’t necessarily hold. But that’s not to say that renewables, especially solar, don’t have some major challenges in order to be effectively utilized. (Detailed post on that here: http://my.ewb.ca/home/ShowPost/14177 ) Some of those challenges do require large scale action, but not one simple solution (that would make the topic too easy and uninteresting :)

Unfortunately most of the discussion in the UK media falls well short of that and there are similar examples in the postings here. I can fully understand why Channel 4 felt it needed to take the contrary shock position against the combined weight of the political lobby and most of our media (that is not to defend the methods of the programme or the shocking response of Martin Durkin to Carl Wunsch’s polite and reasoned critique on the selective editing of his contribution).

Karl Popper wrote at length on the philosophy of science in Conjectures and Refutations. Science should be based on properly developed theories that can be tested and then rejected if found not to accord with experimental evidence.

Science is clearly quite limited when it comes to dealing with complex natural phenomena and the best it seems we can do at the moment – as Carl Wunsch admits – is to take an insurance policy approach.

But it is also quite wrong to mindlessly attack those who question the orthodoxy through genuine scientific inquiry. We are not getting the reasoned refutation at the moment but the proverbial kicking – but then Marcus Brigstock had a go at Lily Allen the previous week so that’s alright then.

This is an immensely difficult area with many unknowns as Carl Wunsch calmly admits. There are also a lot of people with vested interest on both sides of the “argument”. Forgive me if I don’t immediately trust our politicians to tell me about science when they see new industries and new ways of taxing us.

So I freely admit to feeling deeply sceptical about many of the arguments, filtered as they are by “freakanomic” vested interest. I can agree with the insurance policy stance but at the same time I also feel I should finish Svensmark and Calder’s book and explore the possibility that the earth is going to warm up whatever we do. This conjecture appears to be well reasoned and backed up by experimental evidence – which of course does not mean that it will not be refuted at some point in the future.

Channel 4 is normally, I’m sad to say, not actually ‘dodgy’. It broadcasts overall a good selection of stuff – films, documentaries (Dispatches, for instance, which had George Monbiot examining HMG’s laughable attempts to cut our carbon output) and the best US programmes.

But it also has a fatal weakness for shlock, which is why we got the Big Brother debacle from them, and this pile of crap, which C4 thinks was made to stimulate ‘debate’. Indeed, they tried to defend it on the grounds that because part of their remit is to cater for minorities, it was OK programme because a ‘small minority of ‘scientists’ agreed with the programme…
Actually it was incrediably biased, with the usual suspects coming up with long debunked ideas.
Whats really frightened me is the huge number of posts to various newspaper and TV websites saying they were pleased with the programme, they agreed with it, and think that it should repeated! The tone is almost cult-like, with the same discredited points being made over and over again.
There are those of us that do try to post links to the usual websites, but they are simply ignored. Add to that the occasional positive TV review (check out the Times for the 9th), and I’m worried that C4 gave the deniers a massive shot in the arm.
Frankly, it seems many of my fellow countrymen are total idiots, but then again, I shouldn’t be surprised, considering how many of the buy the Sun. But I didn’t think they could switch on a computer, never mind type..
