Fracking Question
Social media postscript: asked here, on Twitter, on Google+, and on Quora. Apologies if you see it more than once. (Not bothering with Facebook.)

Toward Competent Reporting
Emphasis added. Paraphrase: "Scientists have been debating the respective roles of certain climate forcings and climate change in this instance of climate change."Although a normal monsoon has been forecast for South Asia this year, and rains have begun normally in many parts of the region, people are still anxious about the rainy season that lasts for four months.
Their anxiety has to do with the uncertainties surrounding the timing of the monsoon in recent years.
While the debate continues over the role of climate change, scientists have also been looking at the possible role of soot and urban smog pollution in disrupting this weather system.
OK, everybody. These things have different meanings:
anthropogenic climate change
anthropogenic climate forcing
anthropogenic global warming
carbon cycle
carbon dioxide
climate change
global climate change
global change
global warming
greenhouse effect
The best name for "the problem" is "climate disruption", which is shorthand for "dangerous anthropogenic interference in the climate system".
I am not sure I know how to reframe the offending sentence. Admittedly (if I understand their meaning) it is awkward. Perhaps:
"While climate change on the global scale may play a role, scientists have also been looking at the role of local mechanisms such as soot and urban smog in disrupting the monsoon."
The use of the word "debate" was presumably unnecessary and feeds right into denialist tropes.
Another howler:
Ramanathan's result suggested a large reduction of solar radiation at the Earth's surface simultaneous with the warming of the lower atmosphere increases atmospheric "stability". It also slows down the hydrological cycle and reduces rainfall during the monsoon."Also"? What does "stability" mean in this context? Oh, I have no idea so I'll put it in quotes.
This is the worst of it though:
The basic mechanism is agreed, and there is work to be done on quantifying it. There is nothing here resembling what a journalist would call a "debate" which is Wang's point. Such debate is rare in research meteorology. This is not because meteorologist march in lock step on pain of excommunication. It is because meteorology is actually a mature science."The consequence of these contrasting processes needs to be understood before arriving at conclusions on the aerosol impact on a regional climate system," the INCCA said in its statement.
But one of the experts in the recent UNEP/WMO report, Chien Wang of the Massachusetts Institute of Technology (MIT) said there was no confusion on the issue.
"I have to indicate that the basic conclusion that black carbon aerosol forcing over South Asia is large enough to perturb the monsoon system is reached by all the studies so far, therefore there is no different opinion here," he told BBC News.
The point about monsoons and aerosols is interesting, but WTF?
Increasingly I think journalism is too important to leave in the hands of journalists.
A Headscratcher
At first it sounded ludicrous to me. Obviously this is a person who does not Get It. But there's something to think about here.I question whether “training” is the best way to learn about Earth’s Climate System. I think it’s better to actively identify the gaps in your knowledge and seek to fill them. With access to much of written human knowledge in a matter of a few keystrokes and some great professors hanging out in places like WUWT, one isn’t reliant upon trainers. Furthermore, a diversity of sources and opinions is advantageous when studying such an uncertain subject. I think it is better to be well researched, well read, well taught and well learned, than it is to be well trained…
"a diversity of sources and opinions is advantageous when studying such an uncertain subject" is the nut of the question. How do you know that the subject is uncertain? The more diverse your sources the more uncertain you will be, but what does that actually tell you? What you need is to know the diversity of reliable sources, and coming in fresh, you do not know who the reliable sources are.
It seems to me, actually that "training" is not exactly the issue. Many an undergraduate is highly trained in mathematical methods but doesn't understand research; that is the recruiting ground for skeptics and denialists, and the place where the defense of science has been shockingly weak.
The best way to understand research is to obtain a new fact or two that is more or less recognized as such. Those who haven't achieved this are at a disadvantage in identifying where to cull the input on a question in which they take an interest. Perhaps there is some way to make the real intellectual hierarchy more apparent.
How the scientific community winnows and sifts ideas and settles on theories, that is, the details of the social mechanism, changes over time and with the technological and social context. It is in some turmoil right now, as is any communication-intensive pursuit.
The recent process has largely been invisible. It is designed to protect the egos of marginal players. This is why peer review tries to be anonymous and private. But there may be more important goals now.
The appearance of suspicious/hostile amateurs at various levels of competence and seriousness changes the balance of power quite a lot. It may be necessary for scientists to drop all the formal circumspection and be as frank (or "arrogant") in public as they are in private. This is not a time for waffling.
Almost everything is wrong. The superpower of science is the ability to say something is wrong. Jim Bouldin suggests that Wit's End is wrong about tree mortality. I wondered about that. I smell expertise here and so be it; I don't choose to argue the point. It's sort of funny but in a way his response is far more convincing to me than chapter and verse would be. Of course, and this is the point, your mileage may vary.

Employment infographics.
US employment compared to other recessions:
Fastest growing and fastest shrinking categories below. "Other Information Services" includes “publishing and/or broadcasting content exclusively on the Internet”.
Bodes ill for America, but nicely for Texas, don't it? Well, for a few years, anyway. (Where would we be without fracking? And where will we be once we're all fracked out?)
Does anyone seriously those yahoos in the other party could do better? I seriously doubt it - they're the ones that kicked us off the cliff in the first place, remember?
Growth is over, I think. Back to the drawing board.

Rent Seeking, Corruption and Madness
"rent-seeking is an attempt to derive economic rent by manipulating the social or political environment in which economic activities occur, rather than by adding value. An example of rent-seeking is the limitation of access to skilled occupations imposed by medieval guilds."
Washington, D.C. is considering a bill that would require every cab driver in the city to own a special permit called a medallion. The total number of medallions would be capped at 4,000, which would reduce the current number of cabs by more than one-third and put thousands of drivers out of business. (The city government has no idea how many licensed cabs are in the district, though estimates range from 6,500 to 10,000.)
If that weren't bad enough, most drivers wouldn't have the option of buying a medallion. The first set of medallions would be offered for sale to the minority of cabbies who have been driving for at least five years and who live in Washington D.C. (Again the city government has no idea how many current drivers meet this criteria, but rising real estate prices and weak city services have led many drivers to leave the district.)
Who will be offered the next set of medallions, according to the bill? That would be cab companies, who could then rent medallions to drivers. This system would destroy the relatively open-access taxi industry in D.C., in which the majority of drivers are owner-operators free to make their own schedules and keep whatever money they earn on the job. In cities such as New York and Boston, drivers pay upwards of $800 a week to rent their medallions.
A libertarian blog comments:
You can think of two theories of government. One theory is that government exists to correct externalities and provide public goods. The other is that government uses the language of helping people to justify giving stuff to the politically powerful out of the pockets of the rest of us. Here’s some evidence for the second theory.My sympathies are entirely with the small-timers who choose their own hours and can scale their efforts informally to match available demand. Here is a case where the diseconomy of scale is absolutely obvious.

Heartland Musings
I thank Willard for pointing me to a moving piece by Wit's End: "Beware the Banality of Evil - Heartless at the Heartland Institute SICCC"
and Brian Dupuis for alerting me to Chris Mooney's "In the Climate Debate, the Misunderstanding is Mutual", along with (so far) two very interesting replies in the comments thereto.
I'll be responding to the latter myself, shortly. Any others?

Japan national record high for June broken
Sataima sees 39.8 C as heatwave covers JapanTemperatures soared across the Japanese archipelago Friday [June 24 2011], with the mercury reaching 39.8 C in Kumagaya, Saitama Prefecture, a record high for June, due to hot and humid wind flowing from the south, the Japan Meteorological Agency said.
The scorching heat observed in Kumagaya at 2:20 p.m. exceeded Japan’s previous record for June of 38.3 C logged on June 27, 1991, in Shizuoka city, Shizuoka Prefecture.

The Requisite Kluge
King of the Road will be able to picture the scene without any difficulty. I was sitting around Joe Galvin's room doing the usual sort of thing we did in Joe Galvin's room. I recall running the theory by Joe twenty years later and he saud he remembered the conversation much as I did.
Over the Top at Watts Up
"If Tobis took the time to notice, he would see that the rise in [harmless, beneficial] CO2 has been stagnant since the beginning of the year."Oh, well. Just documenting for the ages. For what its worth, this year's CO2 cycle is about 2 ppmv higher than last year's. But I suspect it was the skepticism thing that got me purged.
OK. I just looked. That is wrong. ftp://ftp.cmdl.noaa.gov/ccg/co2/trends/co2_weekly_mlo.txt
You guys are being fed a lot of made up stuff. If you applied a tenth of the skepticism to the stuff you like or wish were true as to the stuff you don't like or hope is false, you might make more progress in understanding what's going on.
