You Ought to Have a Look: On Fixing Science

You Ought to Have a Look is a regular feature from the Center for the Study of Science. While this section will feature all of the areas of interest that we are emphasizing, the prominence of the climate issue is driving a tremendous amount of web traffic. Here we post a few of the best in recent days, along with our color commentary.

This week we focus on an in-depth article in Slate authored by Sam Apple that profiles John Arnold, “one of the least known billionaires in the U.S.” Turns out Mr. Arnold is very interested in “fixing” science. His foundation, the Arnold Foundation, has provided a good deal of funding to various research efforts across the country and across disciplines aimed at investigating how the scientific incentive structure results in biased (aka “bad”) science. His foundation has supported several high-profile science-finding replication efforts, such as those being run by Stanford’s John Ioannidis (whose work we are very fond of) and University of Virginia’s Brian Nosek who runs a venture called the “Reproducibility Project” (and who pioneered the badge system of rewards for open science that we previously discussed). The Arnold Foundation has also provided support for the re-examining of nutritional science, an effort lead by Gary Taubes (also a favorite of ours), as well as investigations into the scientific review process behind the U.S. government’s dietary guidelines, spearheaded by journalist Nina Teicholz.

Apple writes that:

In my conversations with Arnold and his grantees, the word incentives seems to come up more than any other. The problem, they claim, isn’t that scientists don’t want to do the right thing. On the contrary, Arnold says he believes that most researchers go into their work with the best of intentions, only to be led astray by a system that rewards the wrong behaviors.

This is something that we, too, repeatedly highlight at the Center for the Study of Science and investigating its impact is what we are built around.

Apple continues:

[S]cience, itself, through its systems of publication, funding, and advancement—had become biased toward generating a certain kind of finding: novel, attention grabbing, but ultimately unreliable…

“As a general rule, the incentives related to quantitative research are very different in the social sciences and in financial practice,” says James Owen Weatherall, author of The Physics of Wall Street. “In the sciences, one is mostly incentivized to publish journal articles, and especially to publish the sorts of attention-grabbing and controversial articles that get widely cited and picked up by the popular media. The articles have to appear methodologically sound, but this is generally a lower standard than being completely convincing. In finance, meanwhile, at least when one is trading with one’s own money, there are strong incentives to work to that stronger standard. One is literally betting on one’s research.”

Heavy Rains Increasing, but Not Disproportionately So

Global Science Report is a feature from the Center for the Study of Science, where we highlight one or two important new items in the scientific literature or the popular media. For broader and more technical perspectives, consult our monthly “Current Wisdom.”

A new paper has been published in the journal Geophysical Research Letters that examines trends in heavy rainfall amounts across the U.S. The paper is authored by Newcastle University’s Renaud Barbero and colleagues, and, to summarize, finds that the heaviest rainfall events of the year have been increasing in magnitude since 1951 when averaged across nearly 500 stations distributed across the U.S. (note: results from individual stations may differ from the general finding).

Someone with a critical eye might ask the real question, which is “how much?” That such a number does not jump out of this paper—a cynic would say—probably means it is very small. Read on and you will find the answer.

That rainfall on the rainiest day of the year is increasing is, of itself, hardly surprising considering that the total annual rainfall amount averaged across the U.S. has also been increasing during this same period (again, results from individual locations/regions may (and do) depart from this generality).

Changes in heavy rainfall like this are often luridly described as a “disproportionate increase” in extreme events, or that extreme precipitation increases are “worse than expected.”

Some Climate Realities for the Incoming Administration to Consider

While the twitterverse is chirping with concern over Donald Trump’s handling of the global warming science, we offer a few realities that should be key parts of any transitional team’s synthesis.

1. Carbon dioxide is a greenhouse gas that by itself will result in a slight warming of the lower atmosphere and surface temperatures, as well as a cooling of the stratosphere.

     a. All of these have been observed.

 2. Additional warming is provided by a complicated feedback with water vapor. If it were large and positive, so would be future warming.

     a. The observed warming is far below values consistent with a high temperature sensitivity. Therefore future warming will run considerably below any high-sensitivity estimate.

     b. The disparity between observed and forecast warming continues to grow.

You Ought to Have a Look: The Interface of Climate Change Science and Climate Change Policy

You Ought to Have a Look is a feature from the Center for the Study of Science posted by Patrick J. Michaels and Paul C. (“Chip”) Knappenberger.  While this section will feature all of the areas of interest that we are emphasizing, the prominence of the climate issue is driving a tremendous amount of web traffic.  Here we post a few of the best in recent days, along with our color commentary.

We came across a pair of interesting, but somewhat involved reads this week on the interface of science and science policy when it comes to climate change. We’ll give you a little something to chew on from each one, but suggest that you ought you have a look at them at length to appreciate them in full.

First up is a piece, “The Limits of Knowledge and the Climate Change Debate” appearing in the Fall 2016 issue of the Cato Journal by Brian J. L. Berry, Jayshree Bihari, and Euel Elliott in which the authors examine the “increasingly contentious confrontation over the conduct of science, the question of what constitutes scientific certainty, and the connection between science and policymaking.”

Six Decades of Temperature and Precipitation in Kentucky

Air temperature and precipitation, in the words of Chattopadhyay and Edwards (2016), are “two of the most important variables in the fields of climate sciences and hydrology.” Understanding how and why they change has long been the subject of research, and reliable detection and characterization of trends in these variables is necessary, especially at the scale of a political decision-making entity such as a state.

You Ought to Have a Look: A Shout-Out to Lukewarming, a Look at the Republic of Science and a “Roundup” of EPA and Glyphosate

You Ought to Have a Look is a feature from the Center for the Study of Science posted by Patrick J. Michaels and Paul C. (“Chip”) Knappenberger.  While this section will feature all of the areas of interest that we are emphasizing, the prominence of the climate issue is driving a tremendous amount of web traffic.  Here we post a few of the best in recent days, along with our color commentary.

We’ve put together an interesting collection of articles this week for your consideration.

First up is a shout out to lukewarming from Bloomberg View columnist Megan McArdle. In her piece “Global Warming Alarmists, You’re Doing It Wrong,” McArdle suggests that lukewarmers have a lot to bring to the climate change table, but are turned away by the entrenched establishment and tarred with labels like climate “denier”—a label which couldn’t be further from the truth. McArdle writes:

Naturally, proponents of climate-change models have welcomed the lukewarmists’ constructive input by carefully considering their points and by advancing counterarguments firmly couched in the scientific method.

No, of course I’m just kidding. The reaction to these mild assertions is often to brand the lukewarmists “deniers” and treat them as if what they were saying was morally and logically equivalent to suggesting that the Holocaust never happened.

In her article, McArdle calls for less name calling and less heel digging and more open, constructive discussion:

There is a huge range of possible beliefs that go into assessing the various complicated theories about how the climate works, and the global-warming predictions generated by those theories range from “could well be catastrophic” to “probably not a big deal.” I know very smart, well-informed, decent people who fall at either end of the spectrum, and others who are somewhere in between. Then there are folks like me who aren’t sure enough to make a prediction, but are very sure we wouldn’t like to find out, too late, that the answer is “oops, catastrophic.”

These are not differences that can be resolved by name calling. Nor has the presumed object of this name calling – to delegitimize thoughtful opposition, and thereby increase the consensus in favor of desired policy proposals – been a notable political success, at least in the U.S. It has certainly rallied the tribe, and produced a lot of patronizing talk about science by people who aren’t actually all that familiar with the underlying scientific questions. Other than that, we remain pretty much where we were 25 years ago: holding summits, followed by the dismayed realization that we haven’t, you know, really done all that much except burn a lot of hydrocarbons flying people to summits. Maybe last year’s Paris talks will turn out to be the actual moment when things started to change – but having spent the last 15 years as a reporter listening to people tell me that no, really, we’re about to turn the corner, I retain a bit of skepticism.

How was this bit of advice from McArdle received by some of the loudest name-callers? Not well, as she describes in this follow-up:

You Ought to Have a Look: Badges, Ratings and Rewards

You Ought to Have a Look is a feature from the Center for the Study of Science posted by Patrick J. Michaels and Paul C. (“Chip”) Knappenberger.  While this section will feature all of the areas of interest that we are emphasizing, the prominence of the climate issue is driving a tremendous amount of web traffic.  Here we post a few of the best in recent days, along with our color commentary.

Badges? Do we need these stinking badges?

Need, perhaps not, but apparently some of us actually want them and will go to lengths to get them. We‘re not talking about badges for say, for example, being a Federal Agent At-Large for the Bureau of Narcotics and Dangerous Drugs:

But rather badges like these, being given out by the editors of Psychological Journal for being a good data sharer and playing well with others:

A new paper, authored by Mallory Kidwell and colleagues, examined the impact of the Psychological Journal’s badge/award system and found it to be quite effective at getting authors to make their data and material available to others via an open access repository. Compared with four “comparison journals,” the implementation of the badge system at Psychological Journal led to a rapidly rising rate of participation and level of research transparency (Figure 1).

You Ought to Have a Look: Our Energy Future, Science Regress, and a Greening Earth

You Ought to Have a Look is a feature from the Center for the Study of Science posted by Patrick J. Michaels and Paul C. (“Chip”) Knappenberger.  While this section will feature all of the areas of interest that we are emphasizing, the prominence of the climate issue is driving a tremendous amount of web traffic.  Here we post a few of the best in recent days, along with our color commentary.

We’ll jump right into this week by highlighting an appearance by Manhattan Institute senior fellow Mark Mills on The Federalist’s Radio Hour. During his time on the show, Mills explains how the foreseeable future is going to play out when it comes to global energy production and why he says that even if you were concerned about climate change, “there really isn’t anything you can do about it.” 

Mills is one of the leading thinkers and analysts on energy systems, energy markets, and energy policy, bringing often overlooked and deeply-buried information to the forefront.

During his nearly hour-long radio segment, Mills discusses topics ranging from climate change, the world’s future energy mix, the role of technological advances, and energy policy as well as giving his opinions on both Bills Gates’ and Pope Francis’ take on all of the above. It is an entertaining and informative interview.

As a taste, here’s a transcript of a small segment:

In the life we live, and the world we live in, we have to do two things, one is deal with reality [current understanding of physics] and the moral consequences of that, and we can have aspirations. If the aspiration, which Bill Gates’ is, is to use fewer hydrocarbons, we need to support basic research.

We don’t subsidize stuff. The reason we don’t subsidize stuff and make energy more expensive, is because, for me, it is morally bankrupt to increase the cost of energy for most people in most of the world. Energy should be cheaper, not more expensive. We use energy to make our lives better. We use energy to make our lives safer. We use energy to make our lives more enjoyable. Everything that we care about in the world, safety, convenience, freedom, costs energy. [emphasis added]

Mark Mills’ sentiment closely matches that which Alex Epstein explained to Congress a few weeks back and that we highlighted in our last edition. 

If you can find any time to listen to a little or a lot of Mills’ full interview, you’ll probably find that what he says to make a lot of sense. Funny, though, how much of it seems to have escaped some folks.

Next up is an article in the current issue of First Things authored by Walter Wilson titled “Scientific Regress.” If you think the title is provocative, you ought to have a look at the rest of the piece beginning with the first line “The problem with ­science is that so much of it simply isn’t.” Instead, it reflects the results of a gamed system driven by pre-conceived ideas often emanating from the science/political establishment.

Two Millennia of Snowfall Accumulation in Antarctica

Providing the rationale for their work, Roberts et al. (2015) write that “the short and sparse instrumental record in the high latitudes of the Southern Hemisphere means investigating long-term precipitation variability in this region is difficult without access to appropriate proxy records.” It was therefore the objective of this team of nine researchers to extend the duration of the Law Dome, East Antarctica, snowfall accumulation record back in time an additional 750 years so that it would cover over two millennia.

The resultant 2035 year-long proxy (22 BC to 2012 AD) is presented in the figure below. As reported by the authors, the average long-term snow accumulation rate was calculated as 0.686 m yr-1 (27 inches) ice equivalent, which rate they say “is in agreement with previous estimates, and further supports the notion that there is no long-term trend in snow accumulation rates, or that any trend is constant and linear over the [2035-year] period of measurement.”

If this number seems low for such an icy continent, the fact is that most high-latitude locations in both hemispheres would qualify as deserts based upon annual precipitation. In many places, it is literally “too cold to snow” as the frigid air can hold only tiny amounts of moisture.

There were several decadal-scale oscillations in the record, described by the authors as “common,” with “74 events (33 positive and 41 negative) of at least a 10-year duration in the record.”  The three longest periods of above average integrated snowfall occurred over the intervals 380-442, 727-783, and 1970-2009, while the three longest periods of below average integrated snowfall occurred during 663-704, 933-975, and 1429-1468.
