Barbecue summer - the sequel!

Oh, I suppose I shouldn't poke fun. Having got their fingers burnt last year - or perhaps I should say, having had their parade thoroughly rained on - the UK Met Office is declining to offer public forecasts, but is still doing "experimental" research on seasonal prediction and has obviously given a nod and a wink to the author of this Times article.

Of course we all know how the last "barbecue summer" turned out:

“Well, let’s put it this way. I’ve put my barbecue in the shed,” Dave says. “I don’t want it to get any rustier.”

I'm going to be in the UK for a chunk of the summer, so I hope they have got it right this time.

I am reminded that earlier this year, the BBC put out its weather contract to tender. Rumour has it that the esteemed Piers Corbyn, in a change of focus from his current work in volcano and earthquake prediction (no I'm not joking on that bit), is putting in a strong bid.

Climate Physics forum

A new bulletin board for climate science has been set up here. Apparently there used to be a climate section on physicsforums but they closed it down, so one participant (Chris Ho-Stuart) has set one up himself, with the motivation:
Our aim is to support substantive discussion of the science of climate, especially the underlying physics. We focus on ideas that have been published in the mainstream scientific literature. This still allows for all kinds of competing ideas to be considered, while hopefully avoiding distraction from ideas that have no credible basis.
There is already some discussion of the awful G&T paper there (CHS co-authored the comment), and plenty of space for more discussion...

Comment on “Influence of the Southern Oscillation on tropospheric temperature” by J. D. McLean, C. R. de Freitas, and R. M. Carter

Well, it's not really news, but since the energiser bunny was boasting about his comment recently, here is ours, newly published for real:

Comment on “Influence of the Southern Oscillation on tropospheric temperature” by J. D. McLean, C. R. de Freitas, and R. M. Carter

And to save you from the effort of clicking the link, here's the abstract:
McLean et al. (2009) (henceforth MFC09) claim that the El NiƱo–Southern Oscillation (ENSO), as represented by the Southern Oscillation Index (SOI), accounts for as much as 72% of the global tropospheric temperature anomaly and an even higher 81% of this anomaly in the tropics. They conclude that the SOI is a “dominant and consistent influence on mean global temperatures,” “and perhaps recent trends in global temperatures.” However, their analysis is inappropriate in a number of ways and overstates the influence of ENSO on the climate system. This comment first briefly reviews what is understood about the influence of ENSO on global temperatures and then shows that the analysis of MFC09 greatly overestimates the correlation between temperature anomalies and the SOI by inflating the power in the 2–6 year time window while filtering out variability on longer and shorter time scales. The suggestion in their conclusions that ENSO may be a major contributor to recent trends in global temperature is not supported by their analysis or any physical theory presented in their paper, especially as the analysis method itself eliminates the influence of trends on the purported correlations.
Unlike Eli, our comment was so devastating that the original authors were unable to come up with a coherent reply. Oh, ok, that's not so different from Eli's case then!

Here's James exploring some more of "real Japan" on our holiday in April.

Coincidentally, James, after giggling at my pitiful state earlier in the week, is now a quite peaky himself. I hope the rest of JUMP don't get it.

...well - it was time we dieted a bit after our recent extravagances...but it is also sad cos we wanted to climb a snowy mountain this weekend, and now we are far too feeble.

Alternative Voting systems

So the Nasty Party is back in power (I told you before, this blog is strictly neutral on political matters) with the help of the weaselly LibDems. I don't really blame the latter, they had little choice given that Lab/Lib was not viable without numerous fringe parties. I don't think there is much chance of it lasting once the economy heads south, but we will wait and see.

The biggest item of interest to me is the possibility of electoral reform, especially as the economy doesn't affect me so much. It has always seemed absurd that the country should have a dominant Govt supported by only about 35-40% of the voters (which means less than 25% of the electorate by the time the turnout has been accounted for). LDs are supposedly set on "proportional representation" but I haven't actually seen them specify this in detail (nor have I looked). Cons have offered a referendum on Alternative Vote. I think this would be a very big improvement on the current system and think that the arguments against are very weak.

First, those in favour of the current system - usually referred to as "first past the post" which seems bizarre when in fact there is no post, and being first to any specific number of votes is not relevant. Wikipedia calls it "Plurality" which is also a bit cryptic. The supporters seem to believe that what this country needs is "Strong Government", which they claim is best achieved by awarding over 50% of MPs to the party with the most votes, even if a large majority of the electorate opposes them. To those who say, look what FPTP has done for the UK over the past few decades, I reply, yes, by all means look at what it has done, and do you really think that it's worth defending? Lurching from a dominant right-wing govt to an dominant ultra-right-wing government every few years just means they spend most of their time trying to undooutdo the damage that their predecessor did. But mostly, I object to its intrinsic unfairness, invitation to tactical voting and the implication that your vote doesn't matter unless you are in a marginal constituency.

Other possible criticisms of PR are that it may remove the local link from voter to MP, and also that it hands too much influence in the hands of fringe parties like the UKIP, BNP and Greens. On the former point, that is true of some approaches, but not AV. As for the latter, obviously Stoat would like this, but not many others. However, all reasonable proposals like STV generally include a threshold that cuts off the loonies, so this seems like generalised scare tactics rather than a sensible argument. And it doesn't apply to AV in the first place.

I'm disappointed that the Electoral Reform Society has chosen to put such a misleading spin on AV, describing AV as "very much like FPTP" and making a set of amazingly weak and duplicated criticisms in its list of "drawbacks". Yes, AV is not fully proportional, but since no-one advocates fully proportional systems in the first place, this seems somewhat of a straw man. And although there is a theoretical opportunity for tactical voting (as there is in all systems) this is hardly plausible in reality. As obvious and substantial benefits over FPTP, there are no "wasted votes" for minor parties, there is a strong incentive to vote honestly rather than tactically, and the outcome would in practice be substantially closer to proportional (as this BBC page shows for the last election). Their preferred option of STV is not perfect either, but they don't have any list of arguments against it at all!

It should not be overlooked that one large advantage of AV is that it would be simple to implement as a change to the current system. It does not require redrawing boundaries, zoning into regional groups, and (perhaps more importantly) nationally-controlled party lists of top-up MPs that some systems involve. The latter would be an easy target for the press and other critics to oppose.

Enoch was right!

I may have mentioned before how Japan and the Japanese continue to find ways of amusing us, even after almost a decade here...

According to Wikipedia:

"'Enoch was right' is a phrase of political rhetoric, employed by the far right, .... The phrase implies criticism of racial quotas, immigration and multiculturalism."

Oh, but that description relates to "In the United Kingdom, particularly in England". Here in Japan, it's merely the dinner-party conversation of the educated internationalised elite at a highly multicultural gathering.

(Japanese) Jungle Crow, originally uploaded by julesberry2001.

Ever since discovering the cool Yellowstone Ravens last year, I've been trying to enpixelate one of our jungle crows.These birds are big, aggressive, audacious scavengers that shape the way rubbish collection is organised in Japan; it is only put out on the morning of the collection, and covered with netting, or put in crow-proof crates.

It understandable that their relationship with humans is not that great, and I think this might be why they are hard to photograph. They fly away as soon as they see that you are interested in them.

Anyway, this is the best pic so far. I would have liked to have included the tail and more of the red bridge in the photo, but I wasn't quick enough... it flew away before I could frame a better shot.

Wisteria at Hachimangu, originally uploaded by julesberry2001.

Sometimes the extra height of the bipod can really make the picktur. I'm so lucky to have a bipod while all the Japanese have to carry stepladders around...

I wonder what would happen if I bought a blue camera with a flip-out screen as an accessory for my bipod so the automatic composition system could work while the "arms" are fully extended. Could it be that the world is even more exciting viewed from 7.5 feet in the air?
