Did Your SUV Cause the Haiti Earthquake?

The other day, environmental blog the Thin Green Line wrote:

At the American Geophysical Union meeting late last month, University of Miami geologist Shimon Wdowinski argued that the devastating earthquake a year ago may have been caused by a combination of deforestation and hurricanes (H/T Treehugger). Climate change is spurring more, stronger hurricanes, which are fueled by warm ocean waters....

The 2010 disaster stemmed from a vertical slippage, not the horizontal movements that most of the region's quakes entail, supporting the hypothesis that the movement was triggered by an imbalance created when eroded land mass was moved from the mountainous epicenter to the Leogane Delta.

I have heard this theory before, that landslides and other surface changes can trigger earthquakes.  Now, I am not expert on geology -- it is one of those subjects that always seems like it would be interesting to me but puts me in a coma as soon as I dive into it.   I almost failed a pass-fail geology course in college because in the mineral identification section, all I could think to say was "that's a rock."

However, I do know enough to say with some confidence that surface land changes may have triggered but did not cause the earthquake.  Earthquakes come from large releases of stored energy, often between plates and faults.  It's remotely possible land surface changes trigger some of these releases, but in general I would presume the releases would happen at some point anyway.  (Steven Goddard points out the quake was 13km below the surface, and says "It is amazing that anyone with a scientific background could attempt to blame it on surface conditions.")

The bit I wanted to tackle was the Thin Green Line's statement that "Climate change is spurring more, stronger hurricanes."   This is a fascinating statement I want to attack from several angles.

First, at one level it is a mere tautology.  If we are getting more hurricanes, then by definition the climate has changed.   This is exactly why "global warming" was rebranded into "climate change," because at some level, the climate is always changing.

Second, the statement is part of a fairly interesting debate on whether global warming in general will cause more hurricanes.  Certainly hurricanes get their power from warm water in the oceans, so it is not unreasonable to hypothesize that warmer water would lead to more, stronger hurricanes.  It turns out the question, as are most all questions in the complex climate, is more complicated than that.  It may be hurricanes are driven more by temperature gradients, rather than absolute temperatures, such that a general warming may or may not have an effect on their frequency.

Third, the statement in question, as worded, is demonstrably wrong.  If he had said "may someday spur more hurricanes," he might have been OK, but he said that climate change, and by that he means global warming, is spurring more hurricanes right now.

Here is what is actually happening (paragraph breaks added)

2010 is in the books: Global Tropical Cyclone Accumulated Cyclone Energy [ACE] remains lowest in at least three decades, and expected to decrease even further... For the calendar year 2010, a total of 46 tropical cyclones of tropical storm force developed in the Northern Hemisphere, the fewest since 1977. Of those 46, 26 attained hurricane strength (> 64 knots) and 13 became major hurricanes (> 96 knots).

Even with the expected active 2010 North Atlantic hurricane season, which accounts on average for about 1/5 of global annual hurricane output, the rest of the global tropics has been historically quiet. For the calendar-year 2010, there were 66-tropical cyclones globally, the fewest in the reliable record (since at least 1970) The Western North Pacific in 2010 had 8-Typhoons, the fewest in at least 65-years of records. Closer to the US mainland, the Eastern North Pacific off the coast of Mexico out to Hawaii uncorked a grand total of 8 tropical storms of which 3 became hurricanes, the fewest number of hurricanes since at least 1970.

Global, Northern Hemisphere, and Southern Hemisphere Tropical Cyclone Accumulated Energy (ACE) remain at decades-low levels.

The source link has more, and graphs of ACE over the last several decades (ACE is a sort of integral, combining the time-average-strength of all hurricanes during the year.  This is a better metric than mere counts and certainly better than landfall or property damage metrics).

So, normally I would argue with alarmists that correlation is not causation.   There is no point in arguing about causation, though, because the event he claims to have happened (more and stronger hurricanes) did not even happen.  The only way he could possibly argue it (though I am pretty sure he has never actually looked at the hurricane data and simply works from conventional wisdom in the global warming echo chamber) is to say that yes, 2010 was 40-year low in hurricanes, but it would have been even lower had it not been for global warming.  This is the Obama stimulus logic, and is just as unsupportable here as it was in that context.

Postscript: By the way, 2010 was probably the second warmest year in the last 30-40 years and likely one of the 5-10 warmest in the last century, so if warming was going to be a direct cause of hurricanes, it would have been in 2010.    And yes, El Ninos and La Ninas and such make it all more complicated.  Exactly.  See this post.

Post-Apocalyptic Detroit

Some cool pictures of abandoned buildings in Detroit.   How do you abandon a public library and leave all the books?  All these buildings appear vandalized.  Could it be a sign of Detroit's problems that no one bothered to even steal the books?

I can't find the link right now, but these pictures remind me of ones posted a few years ago of Russian towns abandoned after Chernobyl.

My Speaker Project, and Thoughts on a Businesses Liability Kills

I am in the process of building some speakers for my home theater.  This is something I have never done before, but the idea has always intrigued me.  So much so I have actually played around with software and designed a lot of cabinets and crossovers, but never built them.  I am finally going to build an L-C-R for my home theater, and since they go behind my projection screen (the screen is perforated for sound transmission, just like in movie theaters) the pressure to produce flawless cabinetry is reduced significantly.  In fact they will probably be built out of raw MDF finished in black, though I will try to make them look nice just for the practice.

Anyway, one of the reasons I have put off this endeavor is that I do not own a some of the key tools, and do not have the space for these tools.  I have a nice router, belt sander, jig saw, etc.  but I do not have, and really don't have the space for, either a table saw or a drill press.

Which led me to wonder if folks had well-outfitted workshops that they lease out by the hour for such work.  After all, with a good plan in hand, I probably don't need more than an hour on a table saw to get what I need -- most of the project will be in routing the speaker holes and counter sinks, assembly, and sanding/finishing which I can do at home.

Of course, I could not find such a thing.  I could not even find a storage locker that would let me use it as a work shop.  Thinking about this, I am not surprised.   No matter what I get a customer to sign, now matter how well maintained the tools, if someone cuts their hand off using a tool in a stupid and careless way, there is likely going to be a jury somewhere that still wants to assign me liability.

My readers tend to be very nice about rushing to help -- I got about 10 emails offering to help me with my server migrations.  I turned them down because part of the point was to learn to do it myself, and my learning process tends to be by trial and error doing things myself.  Anyway, please do not offer me your shop -- I have found a local community college that allows its shop to be used after one has completed a training and familiarization course (which seems a reasonable precaution).

I am excited about getting started, and am just starting to accumulate the materials.  BTW, in case it becomes relevant to you in the future, a full 4x8 sheet of 3/4-inch MDF is really heavy.

Postscript: I will let you in on my secret ambition.  I really, really want to build a pair of line arrays, as much for their shear bad-ass looks as anything else.  Of course, my wife would freak and I am not sure where they would go in my house, but someday....

Current Law Requires Bastiat's Unseen to Remain Unseen

I find it hard to be surprised nowadays by how low trade policy can sink.  So I was depressed rather than surprised when I read this update on Magnesium trade.

Those of us who complain about protectionism often complain that its proponents mindlessly cite the seen (ie jobs lost to foreign competition) without taking into account the unseen (numerous consumers and consumer industries benefited by imports).  What I did not know is that this is not just bad economics, but is cemented into legislation:

In 2005, U.S. Magnesium Corporation, the sole producer of magnesium in the United States, succeeded in convincing the U.S. International Trade Commission and U.S. Commerce Department to impose duties on imports of magnesium from competitors in Russia and China. Before toasting this outcome with some clichéd or specious utterance about how the antidumping law ensures fair trade and a level playing field for U.S. producers, it is important to understand that downstream, consuming industries (those U.S. producers that require for their own production the raw materials and intermediate goods subject to the antidumping measures) have no legal standing in these cases. Statute forbids the U.S. International Trade Commission from considering their arguments or projections about the likely consequences of prospective duties. Statute requires that the ITC consider only the conditions of the petitioning industry.  In other words, the analysis is slanted.  The antidumping law codifies these evidentiary asymmetries, which makes it easier for U.S. suppliers to cut-off their U.S. customers’ access to alternative sources of supply.

In other words, in the case of magnesium, on the interests of the US Magnesium Corporation can be considered by the US Government in evaluating trade policy - the interest of the other 300 million of us is illegal even to mention.

This was also funny, from the government as Abbot and Costello files:

But on trade policy formulation, it seems that the right hand doesn’t always know what the left hand is doing. Last year, while magnesium imports from China were subject to U.S. antidumping duties, the Obama administration launched a WTO case against China for its restraints on exports of raw materials, including magnesium. That’s right. The U.S. government officially opposes China’s tax on exported magnesium because it imposes extra costs of U.S. consuming industries, but it insists on enforcing its own antidumping duties on magnesium imported from China despite those costs.

Science and Complexity: The Convergence of Climate and Economics

I continue to be fascinated by the similarity between climate science and macro-economics.  Both study unbelievably complex multi-variable systems where we would really like to isolate the effect of one variable.  Because we only have one each of climates and economies  (we can define smaller subsets, but they are always going to be subject to boundary effects from the larger system) it is really hard to define good controlled experiments to isolate single variables.  And all of this is done in a highly charged political environment where certain groups are predisposed to believe their variable is the key element.

In this post by Russ Roberts, one could easily substitute "climate" for "economy" and "temperature" for "unemployment."

Suppose the economy does well this year–growth is robust and unemployment falls. What is the reason for the improvement? Will it be because of the natural rebound of an economy after a downturn that has lasted longer than people thought? The impact of the stimulus finally kicking in? The psychological or real impact of extending the Bush tax cuts? The psychological or real impact of the November election results? The steady hand of Obama at the tiller? All of the above? Can any model of the economy pass the test and answer these questions?

The reason macroeconomics is not a science and not even scientific is that the question I pose above is not answerable. If the economy improves, there will be much talk about the reason. Data and evidence will be trotted out in support of the speaker’s viewpoint. But that is not science. We don’t have a way of distinguishing between those different theories or of giving them weights to measure their independent contribution.

I’m with Arnold Kling. This is a time for humility. It should be at the heart of our discipline. The people who yell the loudest and with the most certainty are the least trustworthy. And the reason for that goes back to Hayek. We can’t measure many of the things we would have to measure to have any reasonable amount of certainty about the chains of connection and causation.

I have heard it said that the only way nowadays to advance pure science is to be working on arcana like the first microsecond of the universe or behavior of the 9th dimension in string theory.   There is still room for a ton of useful work on the analysis, solution, and forecasting of complex multi-variable systems, even if it is just a Goedel-like proof of where the boundaries of our potential understanding can be drawn.

By the way, I wrote my own piece about the limits of macroeconomics here.

News from the Corporate State

I have argued for a while that Obama is building a European-style corporate state, where a troika of powerful government officials, unions, and the largest corporations run the country for their own benefit.  As far as the economy is concerned, this means legislation that cements the position of large, powerful competitors against smaller competitors or future upstarts.  You can see this in Europe, where for decades the list of largest corporations seldom turns over, as they have entrenched themselves in government to protect their position  ().

Here is today's episode, from the Obamacare law:

Under the headline, "Construction Stops at Physician Hospitals," Politico reports today that "Physician Hospitals of America says that construction had to stop at 45 hospitals nationwide or they would not be able to bill Medicare for treatments." Stopping construction at doctor-owned hospitals might not seem like the best way to boost the economy or to promote greater access and choice in health care, but that exactly what Obamacare is doing.

Kenneth Artz of the Heartland Institute explains, "Section 6001 of the health care law effectively bans new physician-owned hospitals (POHs) from starting up, and it keeps existing ones from expanding." Politico adds, "Friday [New Year's Eve] marked the last day physician-owned hospitals could get Medicare certification covering their new or expanded hospitals, one of the latest provisions of the reform law to go into effect."

This little-noticed but particularly egregious aspect of Obamacare is, by all accounts, a concession to the powerful American Hospital Association (AHA), a supporter of Obamacare, which prefers to have its member hospitals operate without competition from hospitals owned by doctors.

Great Model Railroading

For those of you who, when I mention model railroading, think of Lionel trains on a grass mat with a few plastic buildings, check out some of the examples on this site.  In particular, you can't get a much better introduction to fine model railroad craftsmanship than the work of Karl Osolinski.  Enjoy.

Feed Test

Sorry for the feed spam.  A few of you may be using legacy feed addresses that I will have working by the end of the day.  Of course, as I write this I realize that if you are in this situation, you won't be getting this post.  Wow, maybe I should work for the government - spending time and money on public service messages guaranteed not to reach those who might benefit from them.

For the record, the best feed address is always http://feeds.feedburner.com/coyoteblog, which if I have set things up right should be the feed you get when you click the orange feed icon up in the address bar of most browsers.

Site Mostly Fixed

OK, the site is mostly fixed after the site migration.  Had to just let it go down for a while because the site had a permanent forward whose removal took a long while to propagate through the webs.  Still need to rebuild the sidebar but I can do that later today when I get more time.  Hopefully the site will fun faster now -- it certainly is much more responsive running the dashboard.
