Lukewarmers: making the perfect the enemy of the good

There's a very good explanation here by Dana Nuccitelli about the recent paper by Santer and others which identified the problem with some (modest) overestimates of atmospheric warming in modelling.   (It's to do with errors in forcings estimates, not the models themselves.   Climate change denialists instead will claim the models are all wrong and cannot be relied on to make any policy decisions.)

The thing is, the latter is the whole lukewarmer argument, isn't it?   Because the models might not be precisely on point for a certain period, you can never rely on them to make policy decisions.   It's a classic case of making the perfect the enemy of the good.

Incidentally, there was a Science Show recently that gave voice to certain key climate change "skeptics" (you can read the transcript here),  but the one key impression you got listening to it was the age of the voices of the skeptics.   

Tasmanian thoughts

I've posted before about the reasonable house prices in certain parts of Brisbane, and out of curiosity, I've been looking at Tasmania for bargains as well.  

Now, it may have high unemployment and (probably) more than its fair share of ice addicts, but as long as you don't want to live at Sandy Bay in Hobart, the buying is still remarkably good.  Especially if you go to Launceston, where I'll concentrate today.  Look:

Four bedroom, two bathrooms in a pleasing expanded older house, close to the centre of town for 400 and something thousand?

What about this handsome enough looking renovated old place:

Still too expensive?:

Sure, it looks boxy, but it's pretty damn tasteful inside:

This is pretty ridiculous.

I wonder what the fishing is like in the Tamar River?   I'm feeling like a reverse Ratso from Midnight Cowboy, where he says "The two basic items necessary to sustain life are sunshine and coconut milk. Did you know that? That's a fact. In Florida, they got a terrific amount of coconut trees there."

For me, it's more like "The two basic items for life are a cheap but cosy  house, and salmon.  They've got a terrific amount of both in Tasmania."

A culinary observation

I just noticed this at The Guardian:

First, that's a very odd combination of food, if you ask me.


More importantly:   I think brownies are just about the most over rated food thing ever devised.   I mean, I like chocolate (at least, dark chocolate), but a brownie is the biggest waste of chocolate I know of.

That's all...

Diet news

I've been on a 5-2 diet maybe three times now, over a couple of years, because I do indeed put the weight back on if I stop completely.   (I really must follow Michael's advice and go on a permanent 1-6 diet if I want to keep it off.  Or get serious about exercise.) 

So I'm on it again, and I have to say, maybe I like yo-yo dieting.   I mean, as I've said before, the fasting days on the diet (600 cal allowed) really make the small amount of food you do eat taste pretty fantastically good.   (And, as I scrap up every last morsel of salad or cracker crumb, I am also always reminded of the scene in Empire of the Sun where our young hero carefully gathers all of the weevils from his rice and eats them happily.)   There is a sort of feeling of mental focus that can come with the fast days, too.

True, after a few months the novelty wears off, and the reducing speed of the weight loss encourages me to stop at "close enough".   But the early weeks of being on the diet - they feel pretty good.

In other diet news, I see that Eddie McGuire and Malcolm Turnbull have apparently both tried a severe fasting diet over 3 weeks and lost something like 15 kg.  Yeah, I agree with the experts - that's not a good idea.   It might take me a year to lose that much on 5-2, but I can enjoy life on the way.   (By the way, I should lose about 7 kg this time - I really did let myself rebound too far this time.)

She should take the train

From the BBC:

A superstitious elderly passenger delayed a flight in Shanghai after throwing coins at the engine for good luck, a Chinese airline has confirmed.

The 80-year-old woman threw her change at the China Southern Airlines flight as she crossed the tarmac to board.

She told police she launched the coins as she "prayed for safety" on Tuesday.

Of the nine coins launched, only one hit its intended target - but this was enough to force the evacuation of 150 passengers for several hours.

Police were called to Shanghai Pudong International Airport after a passenger noticed the woman's bizarre behaviour, apparently aimed at ensuring a safe flight, and alerted authorities.

Oh dear...

Once again, Helen Dale is attracting attention, and not in a good way: An Award Winning Novelist Is Lifting Viral Tweets.

(She apparently doesn't like Twitter*, so instead of retweets, she just lifts them and puts them on her Facebook page, with no acknowledgement of the source.   But I guess if they are viral, people would often be recognizing the main part as being from elsewhere - and it's not as if people would think she drew a professional cartoon or graphic.    The problem is more the words or caption in a lifted Tweet:  they make it look awfully like her either desiring, or not caring, that some people will think they were her creation too.)

* I was quoting her from the article, though I now see that she is pretty regularly using Twitter - so it seems a very odd explanation.

Update:  I had forgotten, until I re-read her Wikipedia entry, that she had been sacked from writing for the Courier Mail for not acknowledging someone else's jokes she used in a column.    And I'm pretty sure she left Catallaxy after putting up a viral giant pig photo, claiming it was genuine and from people she knew, and then people called her out about that.   It is strange behaviour, and the book tour for her next novel is likely to present more oddities, I expect...

Increasing acceptance

With legalisation of same sex marriage in Australia in the news again, it's interesting to see NPR reports on a new Pew survey result showing that, in the US, public approval of legalising it is still on the rise:

And even Republicans have weakened in opposition:

I guess it's a factor of former opponents not seeing the world change much around them after it's legalised.   There's no reason to believe it wouldn't happen similarly in Australia.

That said, a defensible conservative position remains to have civil unions for those who want the equivalent rights as heterosexual marriage,  but which leave millennial long understandings of the meaning of "marriage" alone.

Sea level rise and climate change

Seems there's a significant new paper on the increasing rate of sea level rise at Nature Climate Change.  I'm waiting for some better explanation of its significance, though.

It is, of course, important to remember how "lumpy" sea level rise will be across the globe.

Hail and climate change

It usually crosses my mind at least once every summer, particularly if hail is falling outside, what effect a warming atmosphere might have on its frequency and size.

Well, some scientists have looked at this for the United States, where it is expected to make a difference:

Anthropogenic climate change is anticipated to increase severe thunderstorm potential in North America, but the resulting changes in associated convective hazards are not well known. Here, using a novel modelling approach, we investigate the spatiotemporal changes in hail frequency and size between the present (1971–2000) and future (2041–2070). Although fewer hail days are expected over most areas in the future, an increase in the mean hail size is projected, with fewer small hail events and a shift toward a more frequent occurrence of larger hail. This leads to an anticipated increase in hail damage potential over most southern regions in spring, retreating to the higher latitudes (that is, north of 50° N) and the Rocky Mountains in the summer. In contrast, a dramatic decrease in hail frequency and damage potential is predicted over eastern and southeastern regions in spring and summer due to a significant increase in melting that mitigates gains in hail size from increased buoyancy.

Reminds me a bit of the complexity of rainfall changes under climate change - with rainfall intensification, but increased drying on hotter days, you might end up with roughly the same amount of rainfall over (say) a year, but more damage caused by the intensity when it does fall.

A Liberal split?

Is it too much to hope for that the Liberals could rid itself of the climate change denying Right in a major party split that was actually initiated over Pyne's not particularly shocking comments that he favours gay marriage coming in soon?   I doubt it will happen - there are too many of them who would need to leave, I think.   But I can't see the conservative forces getting the upper hand in the party room for a leadership spill either - surely they could not contemplate an Rudd-like Abbott rerun, and Dutton has not the slightest hint of any charm that a leader needs.   Who else is there that conservatives could be happy with?

Mind you, it's sort of fun watching the culture warrior Right gnashing their teeth over the centrists in the Liberals having the upper hand.

Wow apology

I've been a bit remiss, because it's been a few weeks since I read this article in Discover magazine on 8 June pretty much debunking the claimed identification of the Wow radio signal as coming from comets.  (Which I had posted about on 6 June.)

Turns out I had very good reason to be skeptical that comets would make a radio signal  of sufficient strength to be mistaken for the Wow signal (or, indeed, that they make radio signals at all.)

So, it's back to the drawing board, I reckon.

Frum on the Republicans

I think David Frum's lengthy article on what has happened with the Republicans sounds pretty convincing.   Worth a read. [Oh wait - it's an old article, just it is popular at the moment in the sidebar at the Atlantic.  I might even have recommended it before!]

Upset at Obama's response to what didn't happen?

It seems to me that there is less outrage in the liberal media than I would have expected with Trump tweeting blame at Obama for not taking more action against the Russians for election interference that Trump has always insisted was "fake news".

Perhaps it's just because no one's surprised anymore by any ridiculous turnaround by this ridiculous President, and how his support base - at the moment - don't care how ridiculous he is.  (Will Steve Kates, the most ridiculous politically commentating economist in Australia, and that's saying something, comment on the turnaround?  I would love to see how he spins it.) 

It's going to take some spectacularly awful stuff to shake his base awake, it would seem.   (Or maybe, just enough incrementally awful stuff - but it's still too soon after the election to see that happen yet.)

Photos from Science

These just caught my eye:

I didn't realise that giraffe skulls looked so much like a dino skull.  Don't you think?

But real dinos were really big: 

 

And numbats are remarkably attractive:

Failure unforeseen (and an excuse to talk about Tom Cruise)

We get Graham Norton's UK chat show about 3 or 4 weeks after it screens there, and it's often very funny.  (It is just about the most relaxed celebrity chat show ever made, I reckon - is it because of the alcohol served?)

Anyway, last night's episode featured Tom Cruise promoting The Mummy (along with his female co-star whose name I don't recall), and Zac Efron, appearing to promote Baywatch.

Both movies were - shortly after that show was taped - pretty much panned by most critics and are already considered box office failures.  (Although, I see that The Mummy has made $300 million internationally in a few weeks of release, so at a claimed production cost of $120 million, it's not a complete disaster - even allowing for the rule of thumb that a movie has to make about 3 times its production costs before it becomes profitable.  Baywatch is doing considerably worse.  But for a complete, it won't even make its production cost disaster, look at Guy Ritchies' King Arthur movie.  Why does anyone employ him?)

However, on last night's appearance on Norton, both Cruise and Efron seemed very genuinely positive about their respective movies.   Either they are really good at faking it; really unable to see defects in their own movies; or the movies are better than what most critics and audiences seem to think.  (I seriously doubt that with respect to Baywatch, where even Zafron was talking about its high quotient of  penis jokes.)

Anyway, somehow while browsing the net after the show, I stumbled across a Simon Pegg twitter account, and he was talking about being in Queenstown, New Zealand, shooting for Mission Impossible 6.  Indeed, it has been in the New Zealand media.  I wonder if NZ is standing in for some other country?
