Wildfires are becoming a perennial favorite of our "Trend that is not a trend" series, showing how media creates trends out of single data points and even out of thin air.  Often, the evidence behind trends in media stories tends to be ... the increasing volume of media stories on that topic.  Thus the "Summer of the Shark" media fiasco.

About 98 out of 100 people I might ask would say that this is a record year for wildfires in the US.  In fact, it is, so far, one of the slowest wildfire seasons in recent memory.

Here is a screencap of the data from the National Inter-agency Fire Center.  Here is the link so you can see for yourself (though of course the data will be different over time since it shows year to date data for the day you check).

Note that there is no apples to oranges BS here -- all data for all years are for Jan 1 to July 24 of that year.  So far this year, the number of fires is 31% below average and the total acres burned is nearly 60% below average.

Postscript:  By the way, I have every reason to hate wildfires.  A wildfire in the Sedona area shut down my largest business for the year, pretty much wiping out our company's earnings for the year.

Postscript #2:  There is clearly a trend in the data for acres burned (see whole database here).  I am not denying the trend, though we can argue how much is climate and how much is forest management and how much is simply more human contact with the wilderness.   What I object to is using individual events, particularly individual events in below-average years, as proof of the trend

An Obama Administration executive order / regulation (hard to tell the difference any more)

Department of Labor
29 CFR Part 10
Establishing a Minimum Wage for Contractors; Proposed Rule

34568 Federal Register / Vol. 79, No. 116 / Tuesday, June 17, 2014 / Proposed Rules

This document proposes regulations to implement Executive Order13658, Establishing a Minimum Wage for Contractors, which was signed by President Barack Obama on February 12, 2014.

The Executive Order therefore seeks to increase efficiency and cost savings in the work performed by parties that contract with the Federal Government by raising the hourly minimum wage paid by those contractors to workers performing on covered Federal contracts to: $10.10 per hour, beginning January 1, 2015; and beginning January 1, 2016, and annually thereafter, an amount determined by the Secretary of Labor.

Liberal and leftish economists in the audience, please explain the line in bold.

The administration wants to apply this to concessionaires as well.  This will force us to raise a $20 camping rate by $4 a night.

With our new prosthetic memory, called the Internet, it should be easy to go back and look at past predictions and see how well those predictions played out.  Heck, sports talk radio hosts do it all the time, comparing their beginning of season predictions with what actually happened.  But no one ever seems to hold the government or politicians similarly accountable.

Here is one I found by accident.  In July of 2011, Kevin Drum quotes this prediction from the CMS (Center for Medicare and Medicaid Services, a government agency).

In 2014, the Affordable Care Act will greatly expand access to insurance coverage, mainly through Medicaid and new state health insurance exchanges which will facilitate the purchase of insurance. The result will be an estimated 22.9 million newly insured people.

In March of 2014 Kevin Drum quotes this from the LA Times

As the law's initial enrollment period closes, at least 9.5 million previously uninsured people have gained coverage. Some have done so through marketplaces created by the law, some through other private insurance and others through Medicaid, which has expanded under the law in about half the states.

The tally draws from a review of state and federal enrollment reports, surveys and interviews with insurance executives and government officials nationwide.

....Republican critics of the law have suggested that the cancellations last fall have led to a net reduction in coverage. That is not supported by survey data or insurance companies, many of which report they have retained the vast majority of their 2013 customers by renewing old policies, which is permitted in about half the states, or by moving customers to new plans.

This is presented as a great victory, but in fact it is nearly 60% below expectations of less than two years earlier.  We don't know the final number.  Drum, who should be expected to be on the optimistic end of projections, has upped his estimate to 11-13 million, but this is still barely half what was expected.   The disastrous Obamacare exchange rollout did one thing at least -- it hammered expectations so low that even a 50% miss is considered a great victory.

One of the great dangers of historical analysis is applying our modern standards and ex post facto knowledge to analysis of historical decisions.  For example, I see modern students all the time assume that the Protestant Reformation was about secularization, because that is how we think about religious reform and the tide of trends that were to follow a century or two later.  But tell John Calvin's Geneva it was about secularization and they would have looked at you like you were nuts (If they didn't burn you).  Ditto we bring our horror for nuclear arms developed in the Cold War and apply it to decision-makers in WWII dropping the bomb on Hiroshima.  I don't think there is anything harder in historical analysis than shedding our knowledge and attitudes and putting ourselves in the relevant time.

Believe it or not, it does not take 300 or even 50 years for these problems to manifest themselves.  They can occur in just four.  Take the recent Halbig case, one of a series of split decisions on the PPACA and whether IRS rules to allow government subsidies of health care policies in Federal exchanges are consistent with that law.

The case, Halbig v. Burwell, involved the availability of subsidies on federally operated insurance marketplaces. The language of the Affordable Care Act plainly says that subsidies are only available on exchanges established by states. The plaintiff argued this meant that, well, subsidies could only be available on exchanges established by states. Since he lives in a state with a federally operated exchange, his exchange was illegally handing out subsidies.

The government argued that this was ridiculous; when you consider the law in its totality, it said, the federal government obviously never meant to exclude federally operated exchanges from the subsidy pool, because that would gut the whole law. The appeals court disagreed with the government, 2-1. Somewhere in the neighborhood of 5 million people may lose their subsidies as a result.

This result isn’t entirely shocking. As Jonathan Adler, one of the architects of the legal strategy behind Halbig, noted today on a conference call, the government was unable to come up with any contemporaneous congressional statements that supported its view of congressional intent, and the statutory language is pretty clear. Members of Congress have subsequently stated that this wasn’t their intent, but my understanding is that courts are specifically barred from considering post-facto statements about intent.

We look at what we know NOW, which is that Federal health care exchanges operate in 37 states, and that the Federal exchange serves more customers than all the other state exchanges combined.  So, with this knowledge, we declare that Congress could not possibly meant to have denied subsidies to more than half the system.

But this is an ex-post-facto, fallacious argument.  The key is "what did Congress expect in 2010 when the law was passed", and it was pretty clear that Congress expected all the states to form exchanges.  In fact, the provision of subsidies only in state exchanges was the carrot Congress built in to encourage states to form exchanges. (Since Congress could not actually mandate states form exchanges, it has to use such financial carrots and stick.  Congress does this all the time, all the way back to seat belt and 55MPH speed limit mandates that were forced on states at the threat of losing state highway funds.  The Medicaid program has worked this way with states for years -- and the Obamacare Medicare changes follow exactly this template of Feds asking states to do something and providing incentives for them to do so in the form of Federal subsidies).  Don't think of the issue as "not providing subsidies in federal exchanges."  That is not how Congress would have stated it at the time.  Think of it as "subsidies are not provided if the state does not build an exchange".  This was not a bug, it was a feature.  Drafters intended this as an incentive for creating exchanges.  That they never imagined so many would not create exchanges does  not change this fact.

It was not really until 2012 that anyone even took seriously the idea that states might not set up exchanges.  Even as late as December 2012, the list was only 17 states, not 37.  And note from the linked article the dissenting states' logic -- they were refusing to form an exchange because it was thought that the Feds could not set one up in time.  Why?  Because the Congress and the Feds had not planned on the Federal exchanges serving very many people.  It had never been the expectation or intent.

If, in 2010, on the day after Obamacare had passed, one had run around and said "subsidies don't apply in states that do not form exchanges" the likely reaction would not have been "WHAT?!"  but "Duh."  No one at the time would have thought that would "gut the whole law."

Postscript:  By the way, note how dangerous both the arguments are that opponents of Halbig are using

1. The implementation of these IRS regulations are so big and so far along that it would be disruptive to make them illegal.  This means that the Administration is claiming to have the power to do anything it wants as long as it does it faster than the courts can work and makes sure the program in question affects lots of people
2. The courts should give almost unlimited deference to Administration interpretations of law.  This means, in effect, that the Administration rather than the Courts are the preferred and default interpreter of law.  Does this make a lick of sense?  Why have a judiciary at all?

The Arizona PIRG has a report that can be summarized as "transit is increasing fast, driving is falling, all of our future investment should be in transit".  The Valley Fever blog has the story:

Arizonans are driving less, and relying more on public transportation, according to a report from the Arizona Public Interest Research Group Education Fund.

The shift is causing the Arizona PIRG Education Fund to recommend that public officials shift funding away from more highway projects, and more toward other transportation options."

"We recommend that transportation officials and elected leaders look at the data today, and not outdated assumptions, to make sure that any highway projects are absolutely necessary," Arizona PIRG Education Fund executive director Diane Brown tells New Times....

In the Phoenix metro area, the light rail opened in late 2008 and is already experiencing ridership numbers that weren't projected to be reached until the year 2020. In 2013, the Valley Metro transit system experienced a record high annual ridership, and between 2007-2013, boardings on Valley Metro transit service jumped from 60 million to more than 75 million - an increase of 25 percent. The Northern Arizona Intergovernmental Public Transportation Authority recently saw its highest monthly ridership in October 2013. And in Yuma, ridership on Yuma County Area Transit has tripled since 2011.

The report suggests that public officials re-allocate their focus and funding, away from building new highways and toward more transportation options.

This is a fantasy.

There is an enormous amount of obfuscation going on here.  The percentage rise of public transit trips is actually the miracle of small numbers -- small changes on an even smaller base.  The point of these charts is to try to say that Arizonans use a lot of transit and we should dump more billions into these projects.  As it turns out, despite all the huge public investment, transit is still a rounding error.

Note that, from their own report, driving vehicle miles per capita are 9175 per person per year.  So lets look at transit.  They exaggerate by showing averages for Phoenix and Tucson, where transit use is higher, not for the whole state like they show vehicle miles.  The total state transit miles per person in the same year, using their numbers, turns out to be as low as 64 (if no one outside of Phoenix or Tucson uses transit) and as high as 110 (if everyone outside of Phoenix and Tucson uses transit at the same rate as in the cities).  The likely number is around 75.

This means that after all these billions and billions of transit spending, transit trips are 0.8% of vehicle trips (75 vs. 9175). That is a rounding error.  You sure wouldn't get that impression from the report.  The Public Interest Research Group has a funny view of "public interest", putting the desired transportation mode of the 0.8% over the desired choice of the 99.2%

Well, you say, I should compare the increase in transit to the decrease in driving.  OK.  Again using their numbers:  Vehicle driving miles went down 348 per capita over the study period.  In the same time, per capital transit miles went up by about 26 in Phoenix and Tucson (likely less in the state as a whole).  So, at best, transit ridership accounts for about 7% of the drop in driving.

This is not nothing, but hardly justifies the enormous increase in transit spending over the last 15 years and the billions and billions in capital investment.

Oh, and by the way, Phoenix Light Rail ridership has cannibalized bus ridership about 1 for 1.  That means all that investment in light rail has just shifted riders to a more expensive, less flexible transit mode.  But that is another story.

A Florida jury awarded the widow of a deceased smoker $23 Billion in punitive damages against RJ Reynolds.

Here is what confuses me -- the $23 billion is obviously not the damages to the woman and her family directly (that was a separate much lower figure) but is somehow calculated as a penalty for RJ Reynolds pursuing bad practices with everyone.  This has to be a penalty for harm to many people, perhaps to all of RJ Reynolds customers.  So what happens when there is a second suit?  Can another person get yet another $23 billion, forcing RJ Reynolds to essentially pay twice for the same bad practices?  Or if a million other ex-customers sued, could RJ Reynolds be forced to pay $23 quadrillion in total? Or should past punitive damages for the same actions be deducted from future awards, saying something like "RJ Reynolds should be penalized $23 billion but that was already paid out to someone else so the net in this suit is zero."

I have no problem suing for actual harm and have opposed limits on regular damage awards -- who can say in advance what the actual damages might have been?  Damage caps tend to be a poor substitute for cleaning up the real problems, which include junk science, no penalty for frivolous suits, and presumption of guilt against deep-pocketed defendants.  But I have never, ever understood punitive damages.

Update:  Jacob Sullum has some related thoughts

Although the main purpose of tort litigation is supposed to be making victims whole, so-called punitive damages explicitly aim to punish wrongdoers. That is usually the function of the criminal justice system, which therefore provides additional protections for defendants, including a higher standard of proof, stricter evidence rules, and penalties prescribed by statute. Attorneys seeking punitive damages do not have to contend with any of those safeguards.

The very concept of punitive damages is oxymoronic, since actual damages (a.k.a. compensatory damages) are a measure of the harm caused by a tort. Punitive damages, by contrast, express a jury's outrage at the defendant's conduct and may be completely unmoored from the injury suffered by the plaintiff (who nevertheless gets the money). In this case, the punitive damages are about 1,400 times the actual damages, which the jury put at $16 million. That huge mutiple seems to violate Florida law, which caps the ratio of punitive to compensatory damages at three or four unless "the defendant had a specific intent to harm the claimant"—a description that clearly does not apply to a tobacco company with millions of customers, even if it prevented them from making informed decisions by hiding the dangers posed by its products.

There are a lot of things out there that generate tons of outrage that do about zero to work me up.  A good example is the recent kerfuffle over a school district assigning kids a debating assignment to argue both sides of the question "Was there actually a Holocaust?"

Certainly this was a fairly boneheaded topic to choose for such an assignment out of the universe of potential topics.   But I will say that this assignment is the type of thing that should be done a LOT more in schools, both in primary schools and in higher education.  Too often we let students make the case for a particular side of an argument without their even adequately understanding the arguments for the other side.  In some sense this brings us back to the topic of Caplan's intellectual Turing test.

I did cross-x debate all the way from 6th grade to 12th.  There is a lot to be said for the skill of defending one side of a proposition, and then an hour later defending the other (that is, if cross-x debate had not degenerated into a contest simply to see who can talk faster).

I remember a few months ago when a student-producer called me for a radio show that is produced at the Annenberg School at UCLA USC.   She was obviously smart and the nature of her job producing a political talk show demanded she be moderately well-informed.  She had called me as a climate skeptic for balance in a climate story (kudos there, by the way, since that seldom happens any more).  Talking to her, it was clear that she was pretty involved in the climate topic but had never heard the skeptic's argument from an actual skeptic.  Everything she knew about skeptics and their positions she knew from people on the other side of the debate.  The equivalent here are people who only understand the logic behind Democrat positions insofar as they have been explained by Rush Limbaugh -- which happens a lot.   We have created a whole political discourse based on straw men, where the majority of people, to the extent they understand an issue at all, only have heard one side talking about it.

I think the idea of kids debating both sides of key issues, with an emphasis on nudging them into trying to defend positions that oppose their own, is a great process.  It is what I do when I teach economics, giving cases to the class and randomly assigning roles (ie you are the guy with the broken window, he is the glazier, and she is the shoe salesman).  The problem, of course, is that we have a public discourse dominated by the outrage of the minority.  It would take just one religious student asked to defend abortion rights or one feminist asked to defend due process rights for accused rapists to freak out, and the school would probably fold and shut down the program.

Which is too bad.  Such discourse, along with Caplan's intellectual Turing test, would be centerpieces of any university I were to found.  When we debated back in the 1970's, there was never a sense that we were somehow being violated by being asked to defend positions with which we didn't believe.  It was just an excersise, a game.  In fact, it was incredibly healthy for me.  There is about no topic I can defend better than free trade because I spent half a year making protectionist arguments to win tournaments.    I got good at it, reading the judge and amping up populism and stories of the sad American steel workers in my discourse as appropriate.  Knowing the opposing arguments backwards and forwards, I am a better defender of free trade today.

The BBC has decided not to every talk to climate skeptics again, in part based on the "evidence" of computer modelling

Climate change skeptics are being banned from BBC News, according to a new report, for fear of misinforming people and to create more of a "balance" when discussing man-made climate change.

The latest casualty is Nigel Lawson, former London chancellor and climate change skeptic, who has just recently been barred from appearing on BBC. Lord Lawson, who has written about climate change, said the corporation is silencing the debate on global warming since he discussed the topic on its Radio 4 Today program in February.

This skeptic accuses "Stalinist" BBC of succumbing to pressure from those with renewable energy interests, like the Green Party, in an editorial for the Daily Mail.

He appeared on February 13 debating with scientist Sir Brian Hoskins, chairman of the Grantham Institute for Climate Change at Imperial College, London, to discuss recent flooding that supposedly was linked to man-made climate change.

Despite the fact that the two intellectuals had a "thoroughly civilized discussion," BBC was "overwhelmed by a well-organized deluge of complaints" following the program. Naysayers harped on the fact that Lawson was not a scientist and said he had no business voicing his opinion on the subject.

...

Among the objections, including one from Green Party politician Chit Chong, were that Lawson's views were not supported by evidence from computer modeling.

I see this all the time.  A lot of things astound me in the climate debate, but perhaps the most astounding has been to be accused of being "anti-science" by people who have such a poor grasp of the scientific process.

Computer models and their output are not evidence of anything.  Computer models are extremely useful when we have hypotheses about complex, multi-variable systems.  It may not be immediately obvious how to test these hypotheses, so computer models can take these hypothesized formulas and generate predicted values of measurable variables that can then be used to compare to actual physical observations.

This is no different (except in speed and scale) from a person in the 18th century sitting down with Newton's gravitational equations and grinding out five years of predicted positions for Venus (in fact, the original meaning of the word "computer" was a human being who ground out numbers in just his way).  That person and his calculations are the exact equivalent of today's computer models.  We wouldn't say that those lists of predictions for Venus were "evidence" that Newton was correct.  We would use these predictions and compare them to actual measurements of Venus's position over the next five years.  If they matched, we would consider that match to be the real evidence that Newton may be correct.

So it is not the existence of the models or their output that are evidence that catastrophic man-made global warming theory is correct.  It would be evidence that the output of these predictive models actually match what plays out in reality.  Which is why skeptics think the fact that the divergence between climate model temperature forecasts and actual temperatures is important, but we will leave that topic for other days.

The other problem with models

The other problem with computer models, besides the fact that they are not and cannot constitute evidence in and of themselves, is that their results are often sensitive to small changes in tuning or setting of variables, and that these decisions about tuning are often totally opaque to outsiders.

I did computer modelling for years, though of markets and economics rather than climate.  But the techniques are substantially the same.  And the pitfalls.

Confession time.  In my very early days as a consultant, I did something I am not proud of.  I was responsible for a complex market model based on a lot of market research and customer service data.  Less than a day before the big presentation, and with all the charts and conclusions made, I found a mistake that skewed the results.  In later years I would have the moral courage and confidence to cry foul and halt the process, but at the time I ended up tweaking a few key variables to make the model continue to spit out results consistent with our conclusion.  It is embarrassing enough I have trouble writing this for public consumption 25 years later.

But it was so easy.  A few tweaks to assumptions and I could get the answer I wanted.  And no one would ever know.  Someone could stare at the model for an hour and not recognize the tuning.

Robert Caprara has similar thoughts in the WSJ (probably behind a paywall)  Hat tip to a reader

The computer model was huge—it analyzed every river, sewer treatment plant and drinking-water intake (the places in rivers where municipalities draw their water) in the country. I'll spare you the details, but the model showed huge gains from the program as water quality improved dramatically. By the late 1980s, however, any gains from upgrading sewer treatments would be offset by the additional pollution load coming from people who moved from on-site septic tanks to public sewers, which dump the waste into rivers. Basically the model said we had hit the point of diminishing returns.

When I presented the results to the EPA official in charge, he said that I should go back and "sharpen my pencil." I did. I reviewed assumptions, tweaked coefficients and recalibrated data. But when I reran everything the numbers didn't change much. At our next meeting he told me to run the numbers again.

After three iterations I finally blurted out, "What number are you looking for?" He didn't miss a beat: He told me that he needed to show $2 billion of benefits to get the program renewed. I finally turned enough knobs to get the answer he wanted, and everyone was happy...

I realized that my work for the EPA wasn't that of a scientist, at least in the popular imagination of what a scientist does. It was more like that of a lawyer. My job, as a modeler, was to build the best case for my client's position. The opposition will build its best case for the counter argument and ultimately the truth should prevail.

If opponents don't like what I did with the coefficients, then they should challenge them. And during my decade as an environmental consultant, I was often hired to do just that to someone else's model. But there is no denying that anyone who makes a living building computer models likely does so for the cause of advocacy, not the search for truth.

As a former hater, I have really enjoyed the World Cup this year.  I think an unsung part of why so many people have been coming around in the States is having ESPN broadcast every game, instead of just seeing two or three here.  Seeing all the games lets one start getting to know the players and the teams, develop favorites, etc.

However, like most Americans, I do find it, at best, humorous to watch folks act like they have been gut-shot every time someone brushes their jersey.  I talked to a friend of mine who used to manage NHL teams, and said that it would be funny to do a parody with ice hockey players falling and writhing on the ground every time they were touched.  There would be 10 guys laying on the ice in about 30 seconds.

Not quite the same idea, but I thought this parody was pretty funny

I was watching some excellent videos of recent Phoenix dust storms roll across the city.  I started thinking about a joke story:

Scientists report that the number of Phoenix dust storms have likely increased substantially since 1990.  Before that date, almost no cell phone videos exist of large dust storms in Phoenix.  Today, one can find hundreds of such videos on Youtube, mostly from the last three or four years.  Obviously we are seeing some sort of climate change

This would clearly be absurd -- there has been a change in measurement technology.  No cell phone cameras existed before 1990.  But equally absurd examples can be found every day.

• With the summer of the shark, an increase in frequency of media coverage of shark attacks was mistaken for an increase in frequency of shark attacks themselves.
• With tornadoes, improving detection of smaller twisters (e.g. by doppler radar and storm chasers)  has been mistaken by many (cough Al Gore cough) for an increase in the frequency of tornadoes.  In fact, all evidence points to declining tornado frequency
• With electrical grid disturbances, a trend was created solely by the government owner of the data making a push with power companies to provide more complete reporting.
• I have wondered whether the so-called cancer epidemic in India is real, or the results of better diagnosis and longer life spans

Postscript:  I remember when I first saw one of these storms rolling towards me after I moved to Phoenix.  Perhaps I should not have read Stephen King's The Mist, but I honestly wondered for a minute if I would live to regret not hopping in my car and racing to stay ahead of the wall coming towards me.

"Trend that is not a trend" is an occasional feature on this blog.  I could probably write three stories a day on this topic if I wished.  The media is filled with stories of supposed trends based on single data points or anecdotes rather than, you know, actual trend data.  More stories of this type are here.  It is not unusual to find that the trend data often support a trend in the opposite direction as claimed by media articles.

I really am not a productivity app sort of guy.  I have a lot of games, but most apps strike me as just dedicated browsers for someone's web site.    To date I am a big user of the Kindle app and the Feedly RSS feed reader app and the Gmail app.   Oh, and Google maps (the Apple maps program still sucks).   And that is about it.

But I have been using Tripcase (free) to bring together all my travel info and I really like it.  All one has to do is forward airline, hotel, car rental, restaurant, etc confirmations to a certain email address and the program parses out what information it needs.  The only work is that each confirmation gets set up as a separate trip, but it is easy to merge three or four together to get all of one trip in a single record.  It provides a nice interface with travel information and provides notifications for such things as flight delays and gate changes.

Well, we had just a mess of problems here.  We have had off and on DOS attacks for a week or so, and then last night I managed to embed some oddball code in a quotation in one of yesterdays posts that caused other heartache.

After a lot of debugging, I am hoping all is well again.  I have changed the caching and security options at Incapsula, which I use as a gateway for traffic.  For many of you, you will see substantial performance improvements but at the cost of some caching which may delay your comments showing up by 10 minutes or so.

One of the factors in the financial crisis of 2007-2009 that is mentioned too infrequently is the role of banking capital sufficiency standards and exactly how they were written.   Folks have said that capital requirements were somehow deregulated or reduced.  But in fact the intention had been to tighten them with the Basil II standards and US equivalents.  The problem was not some notional deregulation, but in exactly how the regulation was written.

In effect, capital sufficiency standards declared that mortgage-backed securities and government bonds were "risk-free" in the sense that they were counted 100% of their book value in assessing capital sufficiency.  Most other sorts of financial instruments and assets had to be discounted in making these calculations.  This created a land rush by banks for mortgage-backed securities, since they tended to have better returns than government bonds and still counted as 100% safe.

Without the regulation, one might imagine  banks to have a risk-reward tradeoff in a portfolio of more and less risky assets.  But the capital standards created a new decision rule:  find the highest returning assets that could still count for 100%.  They also helped create what in biology we might call a mono-culture.  One might expect banks to have varied investment choices and favorites, such that a problem in one class of asset would affect some but not all banks.  Regulations helped create a mono-culture where all banks had essentially the same portfolio stuffed with the same one or two types of assets.  When just one class of asset sank, the whole industry went into the tank,

Well, we found out that mortgage-backed securities were not in fact risk-free, and many banks and other financial institutions found they had a huge hole blown in their capital.  So, not surprisingly, banks then rushed into government bonds as the last "risk-free" investment that counted 100% towards their capital sufficiency.  But again the standard was flawed, since every government bond, whether from Crete or the US, were considered risk-free.  So banks rushed into bonds of some of the more marginal countries, again since these paid a higher return than the bigger country bonds.  And yet again we got a disaster, as Greek bonds imploded and the value of many other countries' bonds (Spain, Portugal, Italy) were questioned.

So now banking regulators may finally be coming to the conclusion that a) there is no such thing as a risk free asset and b) it is impossible to give a blanket risk grade to an entire class of assets.  Regulators are pushing to discount at least some government securities in capital calculations.

This will be a most interesting discussion, and I doubt that these rules will ever pass.  Why?  Because the governments involved have a conflict of interest here.  No government is going to quietly accept a designation that its bonds are risky while its neighbor's are healthy.  In addition, many governments (Spain is a good example) absolutely rely on their country's banks as the main buyer of their bonds.  Without Spanish bank buying, the Spanish government would be in a world of hurt placing its debt.  There is no way it can countenance rules that might in any way shift bank asset purchases away from its government bonds.

Mostly, we use prices to match supply and demand. When supplies of some item are short, rising prices provide incentives for conservation and substitution, as well as the creation of creative new sources of supply.

When we abandon prices, often out of some sort of political opportunism, chaos usually results.

California, for example, has never had the political will to allow water prices to rise when water is short. They cite all kinds of awful things that would happen to people if water prices were higher, but then proceed instead with all sorts of authoritarian rationing initiatives that strike me as far worse than any downsides of higher prices.

In this particular drought, California has taken a page from Nazi Germany block watches to try to ration water

So, faced with apparent indifference to stern warnings from state leaders and media alarms, cities across California have encouraged residents to tattle on their neighbors for wasting water — and the residents have responded in droves. Sacramento, for instance, has received more than 6,000 reports of water waste this year, up twentyfold from last year...

Some drought-conscious Californians have turned not only to tattling, but also to an age-old strategy to persuade friends and neighbors to cut back: shaming. On Twitter, radio shows and elsewhere, Californians are indulging in such sports as shower-shaming (trying to embarrass a neighbor or relative who takes a leisurely wash), car-wash-shaming and lawn-shaming.

“Is washing the sidewalk with water a good idea in a drought @sfgov?” Sahand Mirzahossein, a 32-year-old management consultant, posted on Twitter, along with a picture of a San Francisco city employee cleaning the sidewalk with a hose. (He said he hoped a city official would respond to his post, but he never heard back.)

Drought-shaming may sound like a petty, vindictive strategy, and officials at water agencies all denied wanting to shame anyone, preferring to call it “education” or “competition.” But there are signs that pitting residents against one another can pay dividends.

All this to get, in the best case, a 10% savings. How much would water prices have to rise to cut demand 10% and avoid all this creepy Orwellian crap?

One of the features of Nazi and communist block watch systems was that certain people would instrumentalize the system to use it to pay back old grudges. The same thing is apparently happening in California

In Santa Cruz, dozens of complaints have come from just a few residents, who seem to be trying to use the city’s tight water restrictions to indulge old grudges.

“You get people who hate their neighbors and chronically report them in hopes they’ll be thrown in prison for wasting water,” said Eileen Cross, Santa Cruz’s water conservation manager. People claim water-waste innocence, she said, and ask: “Was that my neighbor? She’s been after me ever since I got that dog.”

Ms. Franzi said that in her Sacramento neighborhood, people were now looking askance at one another, wondering who reported them for wasting water.

“There’s a lot of suspiciousness,” Ms. Franzi said. “It’s a little uncomfortable at this point.” She pointed out that she and her husband have proudly replaced their green lawn with drought-resistant plants, and even cut back showers to once every few days.

Update:  Seriously, for those that are unclear -- this is the alternative to capitalism.  This is the Progressive alternative to markets.  Sure, bad things happen in a free society with free markets, but how can anyone believe that this is a better alternative?

It should not be necessary to say this, but apparently it is:

• The government's reluctance to ban an activity does not constitute an endorsement
• The government's refusal to subsidize an activity does not constitute a ban

Supposedly, there is this huge trend in Millennials graduating college, failing to find a satisfactory job, and ending up living at home.  Almost every media outlet known to man has written about it.  They have anecdotes and pictures of individuals to prove it.  But there does not seem to be an actual trend:

It turns out that the share of young people 18-24 not in college but living at home has actually fallen.  Any surge in young adults living at home is all from college kids, due to this odd definition the Census uses

It is important to note that the Current Population Survey counts students living in dormitories as living in their parents' home.

Campus housing, for some reason, counts in the census as living at home with your parents.  And since college attendance is growing, thus you get this trend that is not a trend.

"Trend that is not a trend" is an occasional feature on this blog.  I could probably write three stories a day on this topic if I wished.  The media is filled with stories of supposed trends based on single data points or anecdotes rather than, you know, actual trend data.  More stories of this type are here.  It is not unusual to find that the trend data often support a trend in the opposite direction as claimed by media articles.

I have yet to meet a skeptic who reports getting any money from mysterious climate skeptics.  A few years ago Greenpeace had a press release that was picked up everywhere about how Exxon was spending big money on climate denialism, with numbers that turned out to be in the tens of thousands of dollars a year.

The big money has always been in climate alarmism.  Climate skeptics are outspent a thousand to one.  Here is just one example

It sounds like the makings of a political-action thriller. The National Geospatial Intelligence Agency (NGA) has awarded Arizona State University a five-year, $20 million agreement to research the effects of climate change and its propensity to cause civil and political unrest.

The agreement is known as the Foresight Initiative. The goal is to understand how climate-caused disruptions and the depletion of natural resources including water, land and energy will impact political instability.

The plan is to create visually appealing computer models and simulations using large quantities of real-time data to guide policymakers in their decisions.

To understand the impacts of climate change, ASU is using the latest advances in cloud computing and storage technologies, natural user interfaces and machine learning to create real-time computer models and simulations, said Nadya Bliss, principal investigator for the Foresight Initiative and assistant vice president with ASU's Office of Knowledge and Development.

I can tell you the answer to this study already.  How do I know?  If they say the security risks are minimal, there will be zero follow-up funding.  If they say the security risks are huge, it will almost demand more and larger follow-up studies.  What is your guess of the results, especially since the results will all be based on opaque computer models whose results will be extremely sensitive to small changes in certain inputs?

Postscript:  I can just imagine a practical joke where the researchers give university officials a preview of results.  They say that the dangers are minimal.  It would be hilarious to see the disappointment in the eyes of all the University administrators.  Never in history would such a positive result be received with so much depression.  And then the researchers would say "Just kidding, of course it will be a catastrophe, it will be much worse than predicted, the badness will be accelerating, etc."

I don't think anyone would say:

• Help!  I have been denied access to housing because my employer won't pay my mortgage
• Help!  I have been denied access to clothing because my employer won't pay my Nordstrom bill
• Help!  I have been denied access to leisure because my employer won't pay my resort bill
• Help!  I have been denied access to child care because my employer won't pay my nanny
• Help!  I have been denied access to food because my employer won't pay my grocery bill

Yet half the country seems to be saying

• Help!  I have been denied access to birth control because my employer won't pay for it

I cannot find a single opposition statement to the Hobby Lobby decision that does not contain some variant of this:

Today, the Supreme Court ruled against women’s basic access to contraceptive healthcare. This decision opens up the door for for-profit companies to impose their personal beliefs on their employees and deny them basic contraceptive care.

Basic healthcare decisions shouldn't be subject to the whims of bosses and employers. ...

I will continue to fight for the right of every woman to make her own private medical decisions. #notmybossbusiness

It seems that a huge number of Americans, even nominally intelligent ones, cannot parse the difference between banning an activity and some third party simply refusing to pay for you to engage in that activity.  This really does not seem to be a complicated distinction, but yesterday I watched something like 40% of America fail to make it.  How is it possible to make any progress on liberty and individual rights if peoples' thinking is so sloppy?

By the way, the passage above is from the Facebook page of Hanna-Beth Jackson, a California state senator.  The reason I find her faux libertarianism initeresting is that Ms. Jackson is co-sponsor of the bill requiring explicit verbal or written consent for each sex act (and each step of the sex act) in California colleges.  A woman's body may not be her boss's business but it appears it is the California government's business, at least according to Ms. Jackson.  This is typical of the abortion and birth control issues, where supporters use libertarian-ish arguments narrowly to defend abortion and contraception rights, but then go all-in for authoritarianism everywhere else.  Jackson's bedroom regulation bill is co-sponsored by Kevin De Leon, who said yesterday "No boss should have the power to interfere with a worker’s personal health decisions."  Because that's his job, I guess.

Stop calling me and other skeptics "climate deniers".  No one denies that there is a climate.  It is a stupid phrase.

I am willing, even at the risk of the obvious parallel that is being drawn to the Holocaust deniers, to accept the "denier" label, but it has to be attached to a proposition I actually deny, or that can even be denied.

As help in doing so, here are a few reminders (these would also apply to many mainstream skeptics -- I am not an outlier)

• I don't deny that climate changes over time -- who could?  So I am not a climate change denier
• I don't deny that the Earth has warmed over the last century (something like 0.7C).  So I am not a global warming denier
• I don't deny that man's CO2 has some incremental effect on warming, and perhaps climate change (in fact, man effects climate with many more of his activities other than just CO2 -- land use, with cities on the one hand and irrigated agriculture on the other, has measurable effects on the climate).  So I am not a man-made climate change or man-made global warming denier.

What I deny is the catastrophe -- the proposition that man-made global warming** will cause catastrophic climate changes whose adverse affects will outweigh both the benefits of warming as well as the costs of mitigation.  I believe that warming forecasts have been substantially exaggerated (in part due to positive feedback assumptions) and that tales of current climate change trends are greatly exaggerated and based more on noting individual outlier events and not through real data on trends (see hurricanes, for example).

Though it loses some of this nuance, I would probably accept "man-made climate catastrophe denier" as a title.

** Postscript -- as a reminder, there is absolutely no science that CO2 can change the climate except through the intermediate step of warming.   If you believe it is possible for CO2 to change the climate without there being warming (in the air, in the oceans, somewhere), then you have no right to call anyone else anti-science and you should go review your subject before you continue to embarrass yourself and your allies.

I watched the Lego Movie last night, and I found it had something very much in common with the recent Transformers franchise movies -- and its not the fact that they both began as marketing platforms for toys.

I don't think it is too much of a spoiler to say that the Lego movie has all kinds of frankly absurd, sometimes nonsensical, plot lines and dialog (though it is surprisingly entertaining at times none-the-less).  What you find out when the camera pulls back midway through the movie is that the first part of the movie is actually pouring from a little boy's imagination as he plays with his Lego blocks.  We are watching a kid playing alone in the basement, making up stories with his toys.

The Lego Movie is the perfect way to understand the most recent Transformers movies.  The Transformers movies don't make a lot of sense in terms of plot and dialog.   But they make perfect sense if you think of them as Michael Bay playing with his digital toys.  The Transformers movies are a little boy running around his room with a couple of action figures yelling "pew pew" and "kaboom", perhaps in front of the Megan Fox poster on the wall, with Michael Bay as the little boy.  The $150 million in digital effects and some irrelevant live actors barely change this fact at all.  (By the way, I have great respect for Bay being able to have fun with his toys and make a billion dollars in the process).

A few thoughts

1. This is one of those "bad policy conflicts with bad policy" decisions that I have trouble getting excited about.   The government should not be mandating tiny details of health insurance policies.  On the flip side, personal religious beliefs should not trump the rule of law (example:  the fact someone has a religion that says it is legal to beat his wife should not create an exception allowing spouse abuse).
2. That being said, the case only seems legally difficult if one completely ignores the existence of the 1993 RFRA, which most on the Left seem to want to ignore.
3. I have zero patience with the facile argument that corporations have no individual rights.  Corporations are just assemblies of people.  Our right to assembly should not cause us to lose our other rights.  If I have freedom of speech as an individual, I don't give it up when I create a corporation.
4. I am even more exhausted with the argument that opposing government subsidies of an activity is the same as opposing the activity itself.  Though half the readers who see this post will assume that I am anti-abortion or anti-contraception, which I am not. (Update:  This seems to be a prevalent argument today, though -- see here)
5. The most ignored fact of this case in my mind is the absolute insanity of the government mandating that regular, predictable purchases be covered in an insurance policy.  Intelligent health insurance policies should no more cover routine contraception than home insurance policies should cover the cost of light bulb replacements.   Sure, I have no problem if some private person wanted such a policy and a private company offered one -- but mandating this craziness is just amazingly bad policy.
6. If you really want to help women and reduce their net cost of contraception, stop requiring a prescription for certain contraceptives, like birth control pills.

Steven Goddard of the Real Science blog has a study that claims that US real temperature data is being replaced by fabricated data.  Christopher Booker has a sympathetic overview of the claims.

I believe that there is both wheat and chaff in this claim, and I would like to try to separate the two as best I can.  I don't have time to write a well-organized article, so here is just a list of thoughts

1. At some level it is surprising that this is suddenly news.  Skeptics have criticized the adjustments in the surface temperature database for years
2. There is certainly a signal to noise ratio issue here that mainstream climate scientists have always seemed insufficiently concerned about.  Specifically, the raw data for US temperatures is mostly flat, such that the manual adjustments to the temperature data set are about equal in magnitude to the total warming signal.  When the entire signal one is trying to measure is equal to the manual adjustments one is making to measurements, it probably makes sense to put a LOT of scrutiny on the adjustments.  (This is a post from 7 years ago discussing these adjustments.  Note that these adjustments are less than current ones in the data base as they have been increased, though I cannot find a similar chart any more from the NOAA discussing the adjustments)
3. The NOAA HAS made adjustments to US temperature data over the last few years that has increased the apparent warming trend.  These changes in adjustments have not been well-explained.  In fact, they have not really be explained at all, and have only been detected by skeptics who happened to archive old NOAA charts and created comparisons like the one below.  Here is the before and after animation (pre-2000 NOAA US temperature history vs. post-2000).  History has been cooled and modern temperatures have been warmed from where they were being shown previously by the NOAA.  This does not mean the current version  is wrong, but since the entire US warming signal was effectively created by these changes, it is not unreasonable to act for a detailed reconciliation (particularly when those folks preparing the chart all believe that temperatures are going up, so would be predisposed to treating a flat temperature chart like the earlier version as wrong and in need of correction.
   
4. However, manual adjustments are not, as some skeptics seem to argue, wrong or biased in all cases.  There are real reasons for manual adjustments to data -- for example, if GPS signal data was not adjusted for relativistic effects, the position data would quickly get out of whack.  In the case of temperature data:
   • Data is adjusted for shifts in the start/end time for a day of measurement away from local midnight (ie if you average 24 hours starting and stopping at noon).  This is called Time of Observation or TOBS.  When I first encountered this, I was just sure it had to be BS.  For a month of data, you are only shifting the data set by 12 hours or about 1/60 of the month.  Fortunately for my self-respect, before I embarrassed myself I created a spreadsheet to monte carlo some temperature data and play around with this issue.  I convinced myself the Time of Observation adjustment is valid in theory, though I have no way to validate its magnitude  (one of the problems with all of these adjustments is that NOAA and other data authorities do not release the source code or raw data to show how they come up with these adjustments).   I do think it is valid in science to question a finding, even without proof that it is wrong, when the authors of the finding refuse to share replication data.  Steven Goddard, by the way, believes time of observation adjustments are exaggerated and do not follow NOAA's own specification.
   • Stations move over time.  A simple example is if it is on the roof of a building and that building is demolished, it has to move somewhere else.  In an extreme example the station might move to a new altitude or a slightly different micro-climate.  There are adjustments in the data base for these sort of changes.  Skeptics have occasionally challenged these, but I have no reason to believe that the authors are not using best efforts to correct for these effects (though again the authors of these adjustments bring criticism on themselves for not sharing replication data).
   • The technology the station uses for measurement changes (e.g. thermometers to electronic devices, one type of electronic device to another, etc.)   These measurement technologies sometimes have known biases.  Correcting for such biases is perfectly reasonable  (though a frustrated skeptic could argue that the government is diligent in correcting for new cooling biases but seldom corrects for warming biases, such as in the switch from bucket to water intake measurement of sea surface temperatures).
   • Even if the temperature station does not move, the location can degrade.  The clearest example is a measurement point that once was in the country but has been engulfed by development  (here is one example -- this at one time was the USHCN measurement point with the most warming since 1900, but it was located in an open field in 1900 and ended up in an asphalt parking lot in the middle of Tucson.)   Since urban heat islands can add as much as 10 degrees F to nighttime temperatures, this can create a warming signal over time that is related to a particular location, and not the climate as a whole.  The effect is undeniable -- my son easily measured it in a science fair project.  The effect it has on temperature measurement is hotly debated between warmists and skeptics.  Al Gore originally argued that there was no bias because all measurement points were in parks, which led Anthony Watts to pursue the surface station project where every USHCN station was photographed and documented.  The net results was that most of the sites were pretty poor.  Whatever the case, there is almost no correction in the official measurement numbers for urban heat island effects, and in fact last time I looked at it the adjustment went the other way, implying urban heat islands have become less of an issue since 1930.  The folks who put together the indexes argue that they have smoothing algorithms that find and remove these biases.  Skeptics argue that they just smear the bias around over multiple stations.  The debate continues.
5. Overall, many mainstream skeptics believe that actual surface warming in the US and the world has been about half what is shown in traditional indices, an amount that is then exaggerated by poorly crafted adjustments and uncorrected heat island effects.  But note that almost no skeptic I know believes that the Earth has not actually warmed over the last 100 years.  Further, warming since about 1980 is hard to deny because we have a second, independent way to measure global temperatures in satellites.  These devices may have their own issues, but they are not subject to urban heat biases or location biases and further actually measure most of the Earth's surface, rather than just individual points that are sometimes scores or hundreds of miles apart.  This independent method of measurement has shown undoubted warming since 1979, though not since the late 1990's.
6. As is usual in such debates, I find words like "fabrication", "lies",  and "myth" to be less than helpful.  People can be totally wrong, and refuse to confront their biases, without being evil or nefarious.

Postscript:  Not exactly on topic, but one thing that is never, ever mentioned in the press but is generally true about temperature trends -- almost all of the warming we have seen is in nighttime temperatures, rather than day time.  Here is an example from Amherst, MA (because I just presented up there).  This is one reason why, despite claims in the media, we are not hitting any more all time daytime highs than we would expect from a normal distribution.  If you look at temperature stations for which we have 80+ years of data, fewer than 10% of the 100-year highs were set in the last 10 years.  We are setting an unusual number of records for high low temperature, if that makes sense.

Loved this passage from Glen Reynolds on the VA:

There's a naive tendency to believe that whatever a government agency's mission is supposed to be, is really the mission that its people pursue. That's seldom the case for long.

Science fiction writer Jerry Pournelle, observing such things, has formulated what he calls the Iron Law of Bureaucracy: In every organization there are two kinds of people: those committed to the mission of the organization, and those committed to the organization itself. While the mission-committed people pursue the mission, the organization-committed people take over the organization. Then the mission-committed people tend to become discouraged and leave.

As a result, the strongest priority of most bureaucracies is the welfare of the bureaucracy and the bureaucrats it employs, not whatever the bureaucracy is actually supposed to be doing. That's worth remembering, whenever someone says they've found something else that we should "choose to do together."

This is not unique to government, but a rule for all organizations.  However, in a private-sector, organizations that devolve in this way get slaughtered (except of course for crony favors and bailouts, but that is another topic).  Accountability never ever comes to government organizations.

Update:  One other observation -- in criticizing Obamacare in advance of its implementation, I never mentioned computer systems problems.  And I always assumed that if you threw enough money and mandates at the problem, the number of uninsured (not to be confused with the number of people with access to quality care) would be reduced.  So all the current triumphalism around Obamacare are about issues that were in fact never raised in advance as criticisms.

One issue that was raised time and again was the information and incentives issues that make it almost impossible to government health care to deliver quality care at a reasonable price.  And the heart of the VA disaster is all an incentives issue.  And it will not get solved.  In part because the incentives issues are endemic to monopoly government services (see: public high schools).  But the government is not even trying to solve the incentives issue.

I read this today in our local paper.  It is written by a local police sergeant and is entitled "Safety tips: How to talk to an officer if you're pulled over"

First, be polite. No good will come of the situation if you are immediately argumentative or uncooperative. Tell your passengers to do the same. You may not agree with the reason for the stop or the outcome, but the side of the road is not the place to debate this. If issued a ticket, you will have your time in court to present your case to a judge or hearing officer....

Do not address the officer with any slang terms or comments. Treat the officer as you would like to be treated, with respect.

Being polite is a nice thing to do.   But no one would write a "safety tip" article about being polite to your Starbuck's server.  Everyone knows the above guidelines are good safety tips (though Chris Rock said it better), but no one mentions the real elephant in the room:  That if you are not polite or not obeisant or somehow "disrespect" an officer, he may well arrest you on a trumped up charge or even physically abuse you.  The stories of this are ubiquitous, and everyone has heard them.  Essentially, the officer writing this is saying to the rest of us that "beware, some police officers are thin-skinned, short-tempered jerks and will abuse you if you do not kowtow to them like some Mandarin emperor."

I guess there is something to be said for the truth in advertising here.  Next week I suppose the DMV will write an article on getting a drivers license that emphasizes bringing a book because their process is so slow and horrible that you are likely to be there all day.
