The importance of context

As a science communicator, I found this fascinating.

The following is an email that was sent in 2003 by a very senior scientist, Stephen Schneider, to a long list of other senior scientists about an article in a newspaper by an economist. Read it and see what you think of the economist, Ross McKitrick at the end. Hello all. Ah ha-the latest idiot-McKitrick-reenters the scene. He and another incompetent had a book signing party at the US Capitol-Mike MacCracken went and he can tell you about it-last summer. McKitrick also had an article-oped, highly refereed of course-in the Canadian National Post on June 4 this year. Here is the URL that worked back then:

It was a scream. He argued there is no such thing as global temperature change, just local-all natural variablity mostly. To prove this he had a graph of temperature trends in Erie Pennsylvania for the past 50 years (this is from memory) which showed a cooling. THat alone proves nothing, but when reading the caption I noticed the trend was for temperature in October and November!! So one station for two months consitituted his "refutation" of global warming-another even dumber than Lomborg economist way out of depth and polemicizing. I showed it to a class of Stanford freshman, and one of them said: "I wonder how many records for various combinations of months they had to run through to find one with a cooling trend?" THe freshman was smarter than this bozo. It is improtant to get that op-ed to simply tell all reporters how unbelievably incompetent he is, and should not even be given the time of day over climate issues, for which his one "contribution" is laughably incompetent. By the way, the Henderson/Castles stuff he mentions is also mostly absurd, but that is a longer discussion you all don't need to get into-check it out in the UCS response to earlier Inhofe polemics with answers I gave them on Henderson/Castles if you want to know more about their bad economics on top of their bad climate science

Double disaster

My latest Mind and Matter column for the Wall Street Journal is about the possibility that big meteorites can trigger volcanic activity:

About 65 million years ago, the dinosaurs and maybe two-thirds of all other species suddenly died out. For three decades, the dominant explanation for this mass extinction has been that it was probably caused by the impact of a large meteorite.

A layer of iridium-rich rock from roughly the right date is the fingerprint that convicted this extraterrestrial killer (iridium is more common in space than in the Earth's crust). Even the bullet hole has apparently been found in the shape of a 110-mile-diameter crater called Chicxulub off the coast of Mexico. The explosion would have been the equivalent of two million hydrogen bombs.

Man-made earthquakes

My latest Mind and Matter column from the Wall Street Journal: Earthquakes are natural disasters. However much culpability there is afterward about the building standards that may have worsened the death toll or the response of the emergency authorities, nobody is to blame for the actual shock.

At least, not normally. An exception is the phenomenon of "induced seismicity," whereby human activity such as geothermal energy projects, mining, gas drilling or the filling of reservoirs apparently sets off swarms of very small earthquakes where there are susceptible geological faults and in certain kinds of underlying rock.

A recent report from the U.S. Geological Survey concludes, for example, that a nearby shale gas well probably caused a swarm of 43 very small earthquakes (largest magnitude, 2.8) in Garvin County, Okla., last January. A few hours before the quakes began, the well had ceased hydraulic fracturing or "fracking": that is, injecting high-pressure water into the ground to crack deep rocks.

Mr Darcy's lack of deodorant

Here's an interview I did for the Globe and Mail in Toronto during my recent visit to Canada.

Nova Demolishes Klein

Joanne Nova has a really fine essay on Naomi Klein. This is great writing, easily as fluent as Klein herself, only rational. An excerpt:

By building her whole argument on un-scientific quicksand, Klein makes mindless statements that unwittingly apply more to her own arguments than anyone elses. She explores "how the right has systematically used crises-real and trumped up-to push through a brutal ideological agenda designed not to solve the problems that created the crises but rather to enrich elites."

No one uses trumped-up-crises better than the left: Which team is demanding billions to "stop the storms"? And which elites will be enriched? The carbon traders and financiers.


My latest Wall Street Journal Mind and Matter column:

The list of scientific heretics who were persecuted for their radical ideas but eventually proved right keeps getting longer. Last month, Daniel Shechtman won the Nobel Prize for the discovery of quasicrystals, having spent much of his career being told he was wrong.

"I was thrown out of my research group. They said I brought shame on them with what I was saying," he recalled, adding that the doyen of chemistry, the late Linus Pauling, had denounced the theory with the words: "There is no such thing as quasicrystals, only quasi-scientists."

You can't change human nature?

Latest Mind and Matter column in the Wall Street Journal:

"You can't change human nature." The old cliché draws support from the persistence of human behavior in new circumstances. Shakespeare's plays reveal that no matter how much language, technology and mores have changed in the past 400 years, human nature is largely undisturbed. Macbeth's ambition, Hamlet's indecision, Iago's jealousy, Kate's feistiness and Juliet's love are all instantly understandable.

Recently, however, geneticists have surprised themselves by finding evidence of recent and rapid changes in human genomes in response to the pressures of civilization. For example, fair skin allows more absorption of the sun's ultraviolet rays necessary for the skin to make vitamin D. So when the northern Europeans, living in a climate with little sunshine, started to farm wheat, a food low in vitamin D, they evolved fair skin to compensate and get more of the vitamin.

reactionary, nostalgic pessimists

There's a fine article at Spiked by Tim Black exposing what Robert* Malthus actually said. Malthus was a reactionary nostalgic pessimist who was not just wrong about population growth outstripping food supply. He was also wrong in his cynicism about helping the poor lest they breed more.

(*Everybody calls him Thomas these days, whereas his contemporaries all called him Robert, which was his second name. Calling him Thomas is like calling the first director of the FBI John Hoover.)

Scientific heresy

Mylecture on scientific heresyto the RSA this week has been reprinted, where it has generated much discussion. Thanks to Andrew Montford and Antony Watts for their interest.
