Dire threats to the National Weather Service?

As I write this, there is much weeping and gnashing of teeth regarding the possibility of massive cuts to the National Weather Service (NWS), including a possible shutdown of the whole Federal government. I'm going to avoid any purely political aspects of this current situation. Instead, I want to offer some perspective on the existing financial 'crisis'.

First of all, during all my 30+ years of working for the Federal Government, I don't recall a single moment when the budget wasn't under pressure. I never experienced a time when everyone was satisfied with, and grateful for, their fiscal support -- it was only a matter of episodic fluctuations in the depth of the continuous 'crisis'! Somehow, we managed to muddle through all those crises, although I must say the long-term trend has been one of declining budgets relative to their buying power (thanks to inflation, among other things). Slowly, but surely, things have deteriorated relative to what they were -- see my essay here for an interpretation of this.

Second, let me begin by saying I'm not an enemy of the NWS! I have no vested interest in seeing them suffer. I have too many NWS friends for that, and though I have no illusions about its management, I believe sincerely that the NWS more than pays for society's investment in its services (perhaps many, many times over!), although it's difficult to put numbers on the return on investment. However -- given that we have only sketchy understanding, at best, of how valuable the NWS products are, it becomes difficult to justify the expense when we have yet another fiscal 'crisis'.

I've suggested via another medium that the cessation of products from the NWS might provide an interesting test of just how valuable their products are to the public they purport to serve. To what extent would an interruption in those services result in major problems for the broad range of public users of weather forecasts? Although I have no evidence to back up what I'm about to say, it seems clear to me that the biggest challenge to the NWS is that there might not be any noticeable effect, as perceived by the majority of the the public!!

Since the NWS has abdicated any meaningful role in product dissemination, preferring instead to leave that for the private sector, that same private sector could (and would) take up a lot of the duties abandoned by the NWS during a financial crisis. And they would do so more than a little gleefully! And it's likely that the products seen by the public would remain at some level close to what they now experience!! This could lead to some embarrassing questions, such as, "If there was so little impact, perhaps it's time for the government to divest itself of this enterprise and allow the private sector to do it?" There have been several attempts by certain political sectors to do just this in the past. Although those attempts were unsuccessful then, the time might be ripe for them finally to win this war. And those pressures will not go away even if they fail once again.

While the annual per capita cost to individual taxpayers for all the NWS services amounts to about the price of a meal at a fast-food restaurant (a huge bargain!), the biggest cost driver for the NWS operation is personnel. If you want to reduce the NWS budget to skeletal levels (e.g., only collecting observations, which the private sector doesn't want to pay for), the fastest way to do so is to cut staffing. Closing offices may be politically difficult, but it's possible that this 'crisis' or the next will see the draconian cuts that everyone in the system fears.

I don't know how to set national priorities (Does anyone?), but I believe that most people aren't particularly concerned about the weather most of the time. They want to know about when it will affect them personally, and they seem to expect perfect forecasts for those occasions when it does affect them, but -- for the majority of the time -- they have other things that concern them. Will there be a groundswell of support for the NWS this time? Maybe. Or maybe not.

Some of us have been anticipating the demise of the human forecaster in the public sector for some time, now. The economics of it are all against the humans. Automated systems run for pennies a day, never go on vacation, and don't get paid after they 'retire'. What's worse is tha human forecasters have, for the most part, chosen to allow the metastasis of meteorological cancer by not doing what it takes to add significant value to automated guidance, which only hastens the day when the economics of this will become so compelling as to result in the loss of those public sector forecaster jobs. I'm pretty confident that NWS managers aren't going to pour gasoline over their heads to help with the budget crisis, despite the bloated NOAA/NWS bureaucracy!

We may yet "weather" this crisis with minimal damage. But there is always another on the horizon. The words of the prophets are written on the Beltway walls and academic halls ... the sounds of silence may yet characterize NWS offices in the future.

Research, travel, and training are easy targets for budget cuts. The NWS does no meaningful training, of course, and they're already stingy with travel (except for bureaucrats). Cutting research will have no short-term impact, of course, but will have devastating results in the future. NWS forecasters argue that they are "essential" personnel (see above), but have little empathy for their research colleagues: when the pie shrinks, the immediate 'family' gets more pie than distant relatives.

Incompatible: Science and superstition

I was watching "How the Universe Works" on the Science Channel today -- a relatively infrequent occasion when the so-called Science Channel actually aired a program about science! -- and it got me to thinking:

If we go back to the time of ancient Greece, the first glimmerings of science began as "Natural Philosophy" with Aristotle, Plato, Socrates, Archimedes, Pythagoras, and Eratosthenes, among others. This was the beginnings of a different approach to understanding the world around us, built on logic and empirical evidence, rather than superstition, mythology, and blind faith. Greek natural philosophers were something very new!

During and after the Renaissance, in fact, the increasingly empirical science being done ran headlong into those entrenched followers of superstition. Copernicus, Galileo, Bacon, Bruno, and many other scientists in Europe suffered persecution and even death at the hands of the Catholic Church because their findings were seen as heretical -- they were incompatible with biblical scriptures. Of course, many famous scientists of the time were faithful christians, as well, including such luminaries and Newton, Leibniz, and Kepler.

Today, we see the same conflicts wherever science offers an interpretation of the way the world works that contradicts cherished scriptural superstitions (and no conflicts where science fails to intersect with scripture). Fortunately, the power of the church (in nontheocracies) has declined to the point where it can't enforce its teaching with torture, imprisonment, and death! Wherever religion and politics are deeply intertwined, of course, the church continues to show its claws when it comes to doubters and unbelievers!

Evolution, deep geological time, modern cosmology -- they all clash with various religious writings and teachings, so we have the growth of a profoundly anti-science movement that coincides with the growing acceptance of religious beliefs here in the USA. That this religious revival is associated with an anti-science movement is not an accident of history. And, as in the past, we have scientists who somehow manage to embrace both science and religion (although they represent a minority among scientists), which I maintain are so diametrically opposed as to deny any rational acceptance of both. I take it as a given that as the stature of the scientist grows, the fraction accepting deistic religious belief declines. The question becomes -- how to explain those scientists who do embrace belief in a deity!

Many aspects of science seem mysterious to non-scientists -- in particular, some say that science requires the same sort of faith that is embodied in religion. This is nothing less than a profound misunderstanding of science. Science offers hypotheses about the natural world that can be tested against evidence, not unsubstantiated claims. The acceptance of a hypothesis requires that it be consistent with the evidence, but its acceptance is always provisional, never final. New evidence may require a revision of the hypothesis, or it may re-affirm the acceptability of an existing hypothesis. The more tests a scientific idea can pass, the more highly regarded that idea becomes, but never to the point of becoming dogma, to be accepted on faith. And, contrary to the claims of some believers, science is never arrogant in its claims to understanding -- good science always is associated with humility in the face of all that scientists have learned we don't yet understand in the very process of gaining new understanding! We labor long and hard to learn the limits to our understanding, and typically resent those who come by their ignorance the easy way!

Religion (at least the major monotheistic faiths that dominate the western and middle eastern world) demands blind faith. Its highest ideal is absolute, child-like obedience and unquestioning faith. Doubt is not permitted, and considered heretical, to say nothing of pointing out religious contradictions with reality. Religion claims sole possession of truth for itself and its self-appointed leaders. When science and religion happen to clash on a subject, the faithful are required to reject science.

Consider what science has given us:
  1. We now know that stars are suns, powered by thermonuclear fusion
  2. We now know that all the matter of the Universe is the condensed energy from the 14 billion year-old "Big Bang" and that the Universe is not at all static and unchanging
  3. We now know that our solar system, with the Sun at its heart, is about 5 billion years old, and includes a host of objects besides the Earth: planets (that are not stars at all, but other worlds), asteroids, comets. etc.
  4. We now know that life has evolved from its earliest beginnings (as yet unexplained) into complex life forms, including we humans, during the existence of the Earth
  5. We now know that volcanoes and earthquakes result from plate tectonics and the processes driven by the heat within the Earth's interior
  6. We now know that storms are the result of processes associated with unequal heating

Many of the gaps in our scientific understanding have been filled, no longer requiring a role for a deity as an "explanation" for that phenomenon. At points in the past, all these things (and more) were not known, and various myths were proposed to "explain" such things, many of which revolved around some deity (many have been postulated!) whose wrath at our lack of belief was responsible for these natural events. Most human beings over the history of our species have lived out their entire lives with only superstition and mythology to explain what they saw around them. They never knew what stars are, they had no idea how we humans came to be here on Earth, and they had no clue as to why they experienced geological and meteorological hazards. Myths were an early, unscientific way, to try to explain things, but science has no place for the "God Hypothesis" as it offers no explanation at all. Gods are the ultimate deus ex machina.

It seems very strange to me to embrace both science and religion, since they involve such contradictory methods regarding knowledge of the world around us. It's at best a monument to the ability of humans to compartmentalize their thinking. The lifelong habits of successful science should disallow the very notion of accepting someone's ideas on faith, without question or doubt.
