Location location location



Barely two week after we put a sign on the gate, we have sold Sea Neuk. At least, the sale is agreed in principle and it's in the hands of the lawyers. The Scottish system (which I've never been involved in before) doesn't seem quite as different from the English one as it is sometimes said, and there is no legally binding contract at this point so I'm not going to say too much about it in case it falls though. But at the time of writing both sides seem very keen to see things through to completion fairly speedily. Having the survey and valuation done in advance does mean there is less to go wrong at this point.

It turned out to be remarkably easy at least in some respects: all we really had to do was to hang a sign on the gate and wait for the crowds to flood in. We also had a short list of people who had said over the years "if you are ever thinking of selling..." and several of them were still seriously interested. We originally set out intending to use an agent, but that didn't work out for various reasons. Of course it was hard work doing the viewings (my sister did the bulk of this), but the whole process only took 2 weeks from start to finish. A standard way of arranging a sale in Scotland is to ask for sealed bids by a specific closing date, but since we were there and able to talk to the hopeful buyers directly we ended up just accepting a verbal (actually emailed) offer which was then repeated formally through the solicitors. I wouldn't necessarily recommend our course of action to everyone trying to sell a house, but it seems to have worked out reasonably well given the circumstances.

Still got the house clearance to think about, but perhaps life will return to normal soon after that...

Boing

Just in case you needed another reason for buying Sea Neuk, it comes with a limitless supply of tasty wild rabbit, like this one which has just had a few hours in the slow cooker with some red wine and a large bunch of rosemary.



My bloodthirsty hungry sister tells me that she's bagged one since I was last there. Actually, before I get savaged by the bunny-huggers, I should let on that I didn't shoot this one either.

Spot the difference

This Greek thing seems to be all the rage on some blogs I could mention, but I struggle to get excited by it. According to the Grauniad website today, The IMF views a debt-to-GDP ratio above 120% as unsustainable. Here, for some context, are some recent data for a couple of countries:



I won't be offering prizes for guessing the identities of Countries A and B. One of them has a collapsing population (1 million down in the past 5y, will be dropping at a rate of 1m per year by 2030), a flatlining economy, and a skyrocketing worker-to-dependent ratio that will exceed unity by the middle of the century (and keep on getting worse). The other is Greece.

Sea Neuk is for sale


Just along the shore from the glass eyesore mentioned in this post, (which incidentally is down to 1.25 million but is still just as ugly and hopelessly overpriced) is a beautiful Victorian villa, which was the first house to be built in the area in the early 1860s. My grandfather bought it in 1953, and for many years my grandmother spent all her summers there (living a short drive away in Edinburgh).

More recently, we've all been living much further away and it hasn't seen so much use. So after a bit lot! of dithering, we have finally and somewhat reluctantly decided to sell it. See more at seaneuk.uk. Serious enquiries welcome.

[jules' pics] garden

flower-1
Almost a year since we completed on our house in Settle. The garden is a bit over-occupied. Being not that large and yet with 5 woodland trees it has an almost continuous canopy to offset its unremittingly sunny aspect. It is similarly full of flowers. They are mostly new to me so I have been mostly just watching them this year. I think the previous people planted a lot of stuff, and there could also a villageurbia effect of things escaping from nearby gardens.

EGU Open discussions

The Hansen paper (submitted manuscript!) has provoked me into mentioning that the EGU are in the process of revamping the discussion phase of their on-line open access publications. There have been a number of complaints over the years that the open publication of the pre-review manuscript can be confusing, as it may lead people to think that these are peer-reviewed publications (which they are not). I've never been particularly convinced by this, and you only have to look at the process to see what is going on, but then again, if people are going to be confused, maybe it is reasonable to wonder if the process could be clarified. A “watermark” on the title page was already added a few years ago, and they have also recently improved the way that the website links and indexes the manuscripts - pointing more clearly to the final paper when available, so people do not read and cite the original version unless they specifically want to.

I'm not sure quite how finalised the new plans are, but at the time of the last EGU meeting one of the proposals was that the authors' own typset manuscript (eg a fairly plain LaTeX template) would be posted up as-is rather than being formatted into the in-house EGU online style. I don't really like the EGU style so that's already an improvement from my perspective. Another potential benefit is that this would eliminate one source of up-front cost which may pave the way for normalising the publiction fee model to a pay-on-(peer-reviewed)-publication model rather than pay-on-submission. There are arguments on both sides of this - pay on submission may reduce the number of poor submissions, but it can be administratively difficult and may lead to both a presumption of acceptance and hard feelings when a paper is rejected.

Ultimately, I don't think these changes will have much effect on the rare cases where people deliberately publicise their submitted manuscrips, as Hansen appears to have done. Most journalists won't understand, or care about, the details of the peer-review process. Nevertheless, I don't have much sympathy for Ken Caldeira's claim that publishing the review process is a form of “pollution” of the peer reviewed literature. No-one sane would routinely read the discussion phase of the journal, and the point behind the publication of these manuscripts is not to double the amount of material that scientists are supposed to read, but to give people the chance both to look at how a particular paper passed through the peer-review process, or to comment on a manuscript that is particularly noteworthy. To that end, I'm happy to see that the Hansen manuscript is well on its way to being the most heavily-commented paper on ACPD, though predictably most of the comments seem to be from crazies. At least they are thereby distracted from commenting on my blog :-)

BlueSkiesResearch.org.uk: Evaluation of CMIP5 palaeo-simulations to improve climate projections


Our latest paper has just appeared in Nature Climate Change: "Evaluation of CMIP5 palaeo-simulations to improve climate projections". It was mainly the brainchild of Sandy Harrison, intended as a response/update to the "preview" paper "Evaluation of climate models using palaeoclimatic data" which promised that the PMIP component of CMIP5 would
provide assessments of model performance, including whether a model is sufficiently sensitive to changes in atmospheric composition, as well as providing estimates of the strength of biosphere and other feedbacks that could amplify the model response to these changes and modify the characteristics of climate variability.
So, how did PMIP do? Well, when we started writing the paper, we looked to see what work had been published that addressed these questions. There was not perhaps quite as much as we might have hoped, but enough to say that
Palaeo-evaluation has shown that the large-scale changes seen in twenty-first-century projections, including enhanced land–sea temperature contrast, latitudinal amplification, changes in temperature seasonality and scaling of precipitation with temperature, are likely to be realistic. Although models generally simulate changes in large-scale circula- tion sufficiently well to shift regional climates in the right direction, they often do not predict the correct magnitude of these changes. Differences in performance are only weakly related to modern-day biases or climate sensitivity, and more sophisti- cated models are not better at simulating climate changes. Although models correctly capture the broad patterns of climate change, improvements are required to produce reliable regional projections.

We started work on the paper around the time we visited Reading last summer, and mostly finished it during our trip to France. Most of the time since then it’s been sitting in limbo waiting for space to be published. It’s pleasing that this travel actually generated a tangible result, which doesn’t always turn out to be the case. And also pleasing that jules and I can continue to make contributions to the literature despite the lack of grey cubicles to spend our days in :-)

4 figures summarise the main results. The first shows that large scale behaviour of the models is consistent between past and future climates (top plots) and that the past climates are consistent with data (bottom plots).
fig1 
However, when we look at some smaller (but still quite large) areas there are substantial problems, with the modelled mid-Holocene monsoon not adequate to support the vegetation that was present in what is now the Sahara desert. In some places, the models barely register any changes at that time, or move in the opposite direction to the data.
fig2 
We summarised the climatologies with a Taylor diagram: the Last Glacial Maximum results show at least a positive correlation between models and data (the temperature results are fairly good), whereas for the mid-Holocene, the model results are clustered close to the zero correlation line (vertical line in the diagram below) and have far too little spatial variability. Pale colours are the older PMIP2/CMIP3 results where available, showing that things have not changed significantly with the new generation of models.
fig3
We also re-examined the question of equilibrium climate sensitivity. This had been raised in the context of CMIP3 by Hargreaves et al in 2012 who asked "Can the Last Glacial Maximum constrain climate sensitivity?" Our answer there did point to the importance of checking this somewhat tentative result with the new CMIP5 results when they became available, and the new results are not so encouraging. In short, there is no detectable correlation between the equilibrium sensitivity of the models, and their simulated LGM cooling. Not that the results are particularly incompatible with the correlation we had previously found either, they just form a rough ball in the right place without a slope either way. There is, perhaps, room to explore this in more detail, and a new paper by Hopcroft and Valdes (which seems to have been written while our paper was in the publication queue) does exactly this. There are question marks over one or two of the models but it’s perhaps a mistake to go too far down this route, as the risks of cherry-picking and post-hoc justification are strong when the ensemble is so small to begin with.

Not much of Harrison et al. will come as a huge surprise to those working in the field, as this paper is basically a review of recent literature rather than hot-off-the-press results. We hope it will serve as a useful summary and perhaps provoke further research in this area.

'Mini ice age' coming in next fifteen years!

Oh no it isn't, despite what you can read in the Indescribablyoverhyped. At most, a solar min might make a detectable reduction in the warming trend. It won't cause significant cooling.

It is not clear to me who is responsible for this made-up story, it could be due to exaggeration from the scientists, a badly worded press release, or a journalist trying to get their story published. But in any case, it's not true.

Oh, thanks to ATTP, the press release seems ok, I can see how the journalist might have got confused. I wonder if she actually spoke to any scientists - solar or climate - before writing her piece.

Wha daur say mass in ma lug?

All this fawning over the pope leaves me rather depressed. So, maybe he happened to say something that was not completely stupid and backward. I suppose perhaps if you are feeling particularly optimistic, that's something to be mildy positive about. But that hardly outweighs the downside of having some cult-leader wielding such authority. It would be far better to not listen to him at all.
