If I read it corre...Thanks very much for all this. If I read it correctly (and please someone correct me if I don't), the Stern Review is quoting as credible an estimate of a 2 to 20% chance of climate sensitivity of greater than 5 C if GHG concentrations stabilised at today's level of approx 430ppm CO2e (part 1, page 9). That is, the Review is suggesting we take seriously the possibility that there is already an up to 1 in 5 chance of an outcome likely to be catastrophic even if all emissions were to stop today. <br /><br />I agree with what you say about the Gordian knots of collective action and intergenerational equity (much of it for babies that don't even look like "us"). These look like incredibly hard challenges to sell to European, or any, publics. ( I have tried to put a brave face on one aspect of part of one of them with a post titled "China: time for a politics of climate change (2)" at jebin08: http://jebin08.blogspot.com/2006/11/china-time-for-politics-of-climate.html. And it is interesting to read that Margaret Beckett has reportedly been feisty in a similar vein in India - see http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2006/11/04/nclim04.xml )<br /><br />I have a lot more to digest in Stern. Does, for example, the Review take account of a range of scenarios of very large refugee flows into Europe (or the costs of keeping people out)? Dealing with blowback from big conflicts resulting from severe water shortage etc in Europe's "near abroad" (Mid East and large parts of Africa) could be more expensive, and more difficult than flood proofing homes in Essex.Caspar Hendersonhttps://www.blogger.com/profile/04667141284390082748noreply@blogger.comtag:blogger.com,1999:blog-28078378.post-37275002259484316872006-11-05T16:45:00.000+00:002006-11-05T16:45:00.000+00:00Greetings Anon...
I agree the report is a good as...Greetings Anon...<br /><br />I agree the report is a good assessment and I think that Stern's 'middle ground' in this debate marks great progress in understanding the risks... My feeling was that the message was just <i>too</i> reassuring - the Chancellor was quick to say that Stern proved that the goal of long-term sustained growth was compatible with fixing the climate. Even if the cost is one percent of GDP (a managaeble £10 billion pa for the UK), the difficulties only begin with this, because there is such tremendous inertia in stock of energy assets and in human behaviour. <br /><br />I may not have read it properly, but my reading of the section on burden sharing and diagram I reproduced is that a cut of 80% would be required for UK/EU by 2050 to achieve a 550ppm stabilisation using the four methodologies mentioned briefly on p. 474-5, rising to about 90% for 450ppm. It looked to me like the report had been 'reviewed' to make sure it was consistent with UK policy of a 60% cut by 2050 being compatible with its findings. Hence the weakness of this section. Too cynical? <br /><br />I was drawing attention to that not because I think an 80% cut by 2050 will be possible or good policy, but because it shows why cracking the collective action problem will be so hard... anything remotely fair and applying objective principles to allocating rights to the global carbon sink, will almost certainly cause the shutters to come down in the developed countries. The collective action problems deepen still further when the intergenerational dimension is included, as you point out. <br /><br />Meanwhile our supposed leadership in this are has barely tamed carbon emissions, which have been rising in the UK - most of our achievement being from the dash for gas in the early 1990s. It makes the 60% cut target look very challenging indeed and will need policy measures far stronger than we have seen so far - and a way of delivering them that does not cause the public to vote out those proposing them. That's a mighty political project! And more than just top slicing one-percent of the economy... <br /><br />All the same, the Stern Review a terrific advance and I still have much of it to digest.Clive Bateshttps://www.blogger.com/profile/15614056019814665135noreply@blogger.comtag:blogger.com,1999:blog-28078378.post-39499479100902175752006-11-05T15:56:00.000+00:002006-11-05T15:56:00.000+00:00I think the Stern Review has struck the right midd...I think the Stern Review has struck the right middle ground – I notice that he has both been criticised by some for being ‘too dramatic and doom mongering’ whilst also being criticised by some environmentalists for being too optimistic in assuming that stabilisation could be achieved at around 550ppm. The Government’s backing of 60% by 2050 target – which its now making statutory – is largely predicated on a stabilisation concentration of 550 ppm. But many studies have recently shown that achieving a stabilisation level of 2 degrees would require an emissions concentration of at least 450 ppm. But the implication of that – as you say – is that the 2050 target would require an 80% perhaps 90% cut in emissions. I think we recognise that asking the public and business to accept such as massive cut would be near impossible. We can’t even currently achieve the manifesto target of 20% by 2010 and whilst Stern is optimistic he is being politically pragmatic. <br /><br />What struck me about the Stern Review was that the ‘economic costs’ of adaptation doesn’t sound all that bad – the additional costs of making new buildings resilient to climate change in the OECD countries is estimated at between 0.05% and 5% of GDP - $15 to $150 billion per year is virtually nothing to developed nations when you put it into perspective. For the UK, the annual flood losses of warming of between 3-4 degrees is actually very small – a cost of 0.2%-04% of GDP by the middle of the century – suggesting we could easily ‘pay’ to adapt to the effects of climate change. Unfortunately, some could therefore use this to interpret that the ‘rich’ developed world therefore needs to do little as ‘we’ll be alright’…. What’s not new is that learning that the real losers will be those in developing countries who will have to deal with the extreme effects of drought and sea level rise and who are less able to bear the costs. The problem that Stern highlights and politics is not well equipped to deal with is that we are in effect asking people in the developed world to make significant changes to their behaviour – purchase less climate impacting products and services and move towards cleaner sources of powering our societies – not necessarily for the benefit of poorer people in developing countries right now – but their children who aren’t even born yet. Try selling that politically.Anonymousnoreply@blogger.com
