Is the taxpayer-funded scientific bureaucracy self-correcting?

4 Comments

Consider this post from Evolution News which talks about a paper in the prestigious pro-naturalism journal Science that is drawing a lot of criticisms. (H/T Melissa, Jonathan)

Excerpt:

Last December we reported on a controversial paper published in Science which claimed to have discovered bacteria that feed on arsenic instead of phosphorous. According to NASA, this research promised to provide “an astrobiology finding that will impact the search for evidence of extraterrestrial life.” At that time the media reported things like:

  • scientists discovered “a bacteria whose DNA is completely alien to what we know today” (Wired)
  • the “bacteria is made of arsenic” (Wired)
  • the bacteria is “capable of using arsenic to build its DNA, RNA, proteins, and cell membranes” (Gizmodo)
  • the paper had reported “arsenic-based life” which is “very alien in terms of how it’s put together” and “NASA has, in a very real sense, discovered a form of alien life” (io9)
  • “you can potentially cross phosphorus off the list of elements required for life” (Nature)

But soon after the original Science paper was published, credible scientists began critiquing the paper’s claims. In the June 3, 2011 issue of Science, several of those scientists have published comments critiquing the original paper. Many of their criticisms focus on the claim that the original paper did not establish or rule out the possibility that the bacteria are not still living off of phosphorous.

So you have a paper being published that everyone is excited about because it helps the naturalists to close gaps in their worldview. But was it good science? The Evolution News piece goes on to list the criticisms of the paper.

And here is the result:

Of course the authors of the original paper, including lead-author Felisa Wolf-Simon, co-authored a reply to the criticisms which should also be read. But critics remain unconvinced. Nature news recently quoted Barry Rosen of Florida International University stating, “I have not found anybody outside of [Wolfe-Simon’s] laboratory who supports the work.” Likewise, Rosie Redfield observes:

“With so many mistakes pointed out, there should be at least some where the authors say, ‘you’re right, we should have done that but we didn’t’,” Redfield says. “This as an entirely a ‘we were right’ response, and that’s a bad sign in science.”

Despite the high levels of skepticism of claims of arsenophilic bacteria, Nature reports that few scientists have taken the initiative to attempt to experimentally reproduce the claims made in the original paper:

However, most labs seem too busy to spend time replicating work that they feel is fundamentally flawed and is not likely to be published in high-impact journals. So principal investigators are reluctant to spend their resources, and their students’ time, replicating the work. “If you extended the results to show there is no detectable arsenic, where could you publish that?” asks Simon Silver of the University of Illinois at Chicago, who critiqued the work in FEMS Microbiology Letters in January and on 24 May at the annual meeting of the American Society for Microbiology in New Orleans. “How could the young person who was asked to do that work ever get a job?” Refuting another scientist’s work also takes time that scientists could be spending on their own research. For instance, Helmann says he is installing a highly sensitive mass spectrometer that can measure trace amounts of elements. But, he says, “I’ve got my own science to do.”

Such admissions do not bode well for those who blindly believe in the perfectly objective, self-correcting nature of science. In this case, it seems safe to experimentally critique these claims since so many respected scientists have already expressed vocal skepticism. Yet experiments are apparently not yet forthcoming. What about areas of science where scientists are not able to express their dissent freely? For example, who would take time to experimentally critique claims that are central to neo-Darwinian theory, especially if it’s dangerous to one’s career? One hopes that science will become more self-correcting when it comes to claims made in support of materialism.

In light of what we now know about global warming research, shouldn’t we be a little more welcoming of whistleblowers and critics? Shouldn’t we be a little more careful about hastily approving research that agrees with the religion of naturalism, instead of checking it over thoroughly to make sure that it really is good science?

Jay Richards asks: what should Christians believe about global warming?

From Boundless.

Excerpt:

The big environmental issue nowadays is global warming. Anyone who watches or reads the news even occasionally has been told that humans are causing global warming through all the fossil fuels we’re burning. They’ve also been told that this warming process eventually will prove catastrophic if we don’t reverse course as soon as possible.

As thinking Christians and good stewards, how should we respond?

The short answer is, we should respond thoughtfully. Thoughtless stewards are rarely good stewards.

Notice that my brief summary of the global warming controversy bundled together several distinct claims. To think clearly about this issue, we have to tease apart this bundle of claims and consider each one. For each claim, there is a corresponding question we need to answer. And it’s only after answering these questions that we can be in a position to determine what, if anything, we ought to do about global warming.

Here are the four central questions:

  1. Is the earth warming?
  2. If the earth is warming, is human activity (like carbon dioxide emissions) causing it?
  3. If the earth is warming, and we’re causing it, is that bad overall?
  4. If the earth is warming, we’re causing it, and that’s bad, would any of the proposed “solutions” (e.g., the Kyoto Protocol, legislative restrictions on carbon dioxide emissions) make any difference?

Former alarmist scientist admits global warming is a “fiction”

Leave a comment

David Evans consulted full-time for the Australian Greenhouse Office (now the Department of Climate Change) from 1999 to 2005, and part-time 2008 to 2010, modelling Australia’s carbon in plants, debris, mulch, soils, and forestry and agricultural products. And then he stopped working for them. Now that he is no longer obligated to toe the party line, he explains what global warming really is about. (H/T Neil Simpson)

Excerpt:

The debate about global warming has reached ridiculous proportions and is full of micro-thin half-truths and misunderstandings. I am a scientist who was on the carbon gravy train, understands the evidence, was once an alarmist, but am now a skeptic. Watching this issue unfold has been amusing but, lately, worrying. This issue is tearing society apart, making fools out of our politicians.

Let’s set a few things straight.

The whole idea that carbon dioxide is the main cause of the recent global warming is based on a guess that was proved false by empirical evidence during the 1990s. But the gravy train was too big, with too many jobs, industries, trading profits, political careers, and the possibility of world government and total control riding on the outcome. So rather than admit they were wrong, the governments, and their tame climate scientists, now outrageously maintain the fiction that carbon dioxide is a dangerous pollutant.

The evidence that was ignored by the global warming alarmists:

Most scientists, on both sides, also agree on how much a given increase in the level of carbon dioxide raises the planet’s temperature, if just the extra carbon dioxide is considered. These calculations come from laboratory experiments; the basic physics have been well known for a century.

The disagreement comes about what happens next.

The planet reacts to that extra carbon dioxide, which changes everything. Most critically, the extra warmth causes more water to evaporate from the oceans. But does the water hang around and increase the height of moist air in the atmosphere, or does it simply create more clouds and rain? Back in 1980, when the carbon dioxide theory started, no one knew. The alarmists guessed that it would increase the height of moist air around the planet, which would warm the planet even further, because the moist air is also a greenhouse gas.

This is the core idea of every official climate model: For each bit of warming due to carbon dioxide, they claim it ends up causing three bits of warming due to the extra moist air. The climate models amplify the carbon dioxide warming by a factor of three — so two-thirds of their projected warming is due to extra moist air (and other factors); only one-third is due to extra carbon dioxide.

That’s the core of the issue. All the disagreements and misunderstandings spring from this. The alarmist case is based on this guess about moisture in the atmosphere, and there is simply no evidence for the amplification that is at the core of their alarmism.

Weather balloons had been measuring the atmosphere since the 1960s, many thousands of them every year. The climate models all predict that as the planet warms, a hot spot of moist air will develop over the tropics about 10 kilometres up, as the layer of moist air expands upwards into the cool dry air above. During the warming of the late 1970s, ’80s and ’90s, the weather balloons found no hot spot. None at all. Not even a small one. This evidence proves that the climate models are fundamentally flawed, that they greatly overestimate the temperature increases due to carbon dioxide.

This evidence first became clear around the mid-1990s.

At this point, official “climate science” stopped being a science. In science, empirical evidence always trumps theory, no matter how much you are in love with the theory. If theory and evidence disagree, real scientists scrap the theory. But official climate science ignored the crucial weather balloon evidence, and other subsequent evidence that backs it up, and instead clung to their carbon dioxide theory — that just happens to keep them in well-paying jobs with lavish research grants, and gives great political power to their government masters.

These revelations should mark the end of global warming alarmism, but they won’t, because global warming is such a useful fiction for so many people. As the article noted, it’s a source of endless research grants and prestigious travel budgets for researchers in academia who must apply for government money before they can prove what the governments wants them t0 prove – namely, that government needs to control individuals and corporations. It provides those who reject traditional morality with a way of feeling better about themselves by being “moral” about recycling, turning of their lights and not having any children. It gives people a feeling of pride, because they are better than those greedy oil companies that pay a 40% tax rate, much higher than the 0% paid by companies that are favored by the Democrat Party, like GE. It also provides a useful fiction for the socialists to mislead the public into voting for them to “solve” the “crisis” with bigger government, higher taxes and less individual liberty.
