Thom Hartmann Does It Too
I mostly like Thom Hartmann, because he seems thoughtful. At least, more thoughtful than the right-wing commenters, by far. But he also seems very biased towards the left, sometimes reflexively so.
Some caller to his show was asking about solar energy, and Hartmann's response was that solar was cheaper than all other sources and he didn't know why the media wasn't reporting this, but it was probably because Big Oil/Gas/Coal had bought the media with ads and other payoffs.
And that was disappointing, because I had just happened to read a very good article about this, and it made a solid impression on me, so I knew immediately that Hartmann was wrong. What's worse is that he immediately dived to a token extreme left position -- media bought off by corporate America -- when he had no evidence of that and, worse, no understanding of the real situation at all (which is always more complex that can fit into their small thoughtless catch phrases).
Simply because I read this one article, and understood it, Hartmann looked very small and very stereotypical, and not in a good way. Those kind of instances come along from time to time -- for you too I'm sure -- and they color what you hear/read afterward. It's kinda of a quantum change.
Hartmann was just flat out wrong. As was his excuse. As this Bloomberg Technology article covers in good detail, solar is now cheaper where electricity demand is growing and where the capitalization costs of its plants (or farms) competes directly with capitalization costs of coal/gas plants.
That's the case in many nations, in Africa, in Asia, and the like -- but not the case in the US. Here coal plants, and many gas plants, have already been built and are either paid off or are being paid off. They have a big jump on capitalization costs, and, I don't know for sure, but suspect, on writing off those capitalition costs.
Solar farms are new right out off start. The Ivanpah solar farm in Nevada cost $2.2 B to construct before any electricity was ever delivered. That's a lot of headway.
--
My purpose here isn't to compare prices per kWh to the nearest tenth of a penny and do a full life-cycle cost projection. It's just to point out how eager Thom Hartmann was to blame Big Corp when he really had no understanding of the issue at all.
I found that disappointing.
I sent an email to Hartmann about this, but of course never heard back.
And isn't that the world we live in these days? The bigger their audience, the bigger their lies -- oops, their misspeakings -- and all the less interest they have in trying to be right, admist all the complexity.
Hartmann, Limbaugh, Hannity, all of them -- they don't care about the truth. They just want to spout, and get to the next commercial.
Hell, if they ever wavered, or said they just didn't know, we're probably all punch the button for the next channel we have stored in our console.
The next many years are looking to be a lousy time for anyone who cares about the truth and thinks it isn't all that simple at all. Perhaps.
You really can't ever ask enough questions. Don't trust anyone, as far as possible.

Suyts likes to insult everyone, while using a fake name himself. I resolved to show him how that felt. Clearly I made that clear to him, and it stung.

John Fleck's "Water is for Fighting Over"
The first thing to realize is that the title is intentionally misleading, even a little risky. It's full title is, "Water is for Fighting Over: And Other Myths About Water in the West."
The subtitle makes all the difference.
Because Fleck took a different, refreshing turn on the subject.
Disclosure: I know John and have had dinner with him a time (or two?) when I was back in Albuquerque on family business. (My mother, now deceased, lived there, and my dad still does. I went to the University of New Mexico after we moved there in the late 1970s,after the steel industry fell apart in southwestern Pennsylvania. I was an undergraduate there for three years, and graduated with a BA in math and physics.) John is a really great guy, and maybe that influences my review here a little bit. Frankly, it should.
It's easy to look at the Colorado River, which not long ago didn't release a cubic centimeter of water into the Gulf of California. Seven US southwestern states all wanted a share of the river's water. State-by-state quotas were established in the 1920s, the worse time of all because the river was then at long-term highs, not at all typical of the present decades, or of today's droughts.
There were arguments and lawsuits. Every state struggled to get as much water as it could with the 1922 Law of the River, an edict that sounds like something happy out of Middle Earth. Issues went to the Supreme Court, some cases lasting more than a decade.
The glory of Fleck's book is that he saw through all these struggles between one state's agency's position, Mexico's interests (often ignored), California's seemingly inexhaustible thirst (kind of a bully), thirsty Arizona and Las Vegas, and the ever-forgotten Native Americans.
He recognized that these had, in recent years, been superceded by a network, a network of people from state agencies, tribes, environmental groups and more, who came to realize that working together, quietly in the background, hashing out their differences at conferences of specialists and friends, at happy hours afterward, at small gatherings at hotels in the region -- that this approach worked better, more smoothly, more fruitfully in overcoming differences and finding a way to real agreements. Person-to-person. And to this day.
That's not easy for a writer to recognize. It would have been much easier to write a book about all the looming shortages of Colorado River water, how (it's claimed) it simply cannot meet all the water needs of the big southwestern cities, and southern California as well. But Fleck drove all over the southwest, watching dams open and talking quietly to the state and national officials who made those happen. The water kept flowing.
That's Fleck's second significant realization -- that, when water is scarce, regions and cities and states learn how to make due with less. It isn't a mano-to-mano struggle over every last drop of water -- water managers have learned that there is no hope for one if there isn't hope for all. Albuquerque, Las Vegas, LA -- all have made major strides in water conservation. And John had the foresight to recognize that, and write about it.
So this book isn't an update to Marc Reisner's 1986 Cadillac Desert. Fleck's book looks deeper, for the real story, the human story of how people are making it work, and it finds optimism. And that isn't a message a writer finds every day, or, either, that the reader hears every day.
John blogs here.
Legal Action Against Joanne Codling (Jo Nova)
Every bit of her post here is a lie, and libelous, and she hasn't any proof at all except hearsay and the lies of others:
This lie comes from "Phil Jourdan" (who I've heard might be "mpainter" who was banned from Roy Spencer's blog). You'll notice he accused me of "stalking and threatening children," which in no way does his citation support. He's on the list too.
This also is full of lies, which he said came from the fake name "Suyts" at Wordpress, real name "James Sexton":
BTW, James Sexton wrote this over three years ago, but I pay so little attention to him I didn't see it until now.
I have already been in touch with Wordpress about Sexton's libelous post.

Arctic Sea Ice Volume Now Down 45%
(Have I said yet how crappy Windows 10 is? And Excel 365? They are barely worth a beta release; I will never buy anything made by Microsoft ever again. Same with Hewlett Packard -- I bought an HP ENVY in late June for $700, and so much doesn't work on it that I'd like to throw it across my fence and be done with it. Extremely disappointing. I've bought HP products before -- a laptop and more than one printer -- but this product is a complete piece of junk. And, no, I'm not willing to spend endless hours on a phone with a technician trying to make all the mistakes better.)
Anyway, Arctic SIV is declining steadily and scarily. In less than just 40 years.

A Sticking Point About the Movie "Alliance"
This isn't giving anything away that's not in the trailers, until I warn you. In the picture to the right is symbol containing a sentence (or some complicated thought) of the alien's language. The plot evolves around a linguist's (Amy Adams) ability to translate such symbols and so try to communicate with the aliens. Before this she approached them with a whiteboard on which she'd write her name or a word from English, but that didn't work.
Instead she works on translating their language. The way they show her doing this is good stuff -- she tries to break down parts of the loop (and they're always loops) into individual "words" or "thoughts" or "feelings" or the equivalent. Eventually she succeeds somewhat, but it's too late and the politicans of the world take to aggressively dealing with what they see as a massive threat to the and to Earth. (There are about 12 of these ships at various points around the globe.) Of course that ruins everything.
Now you should stop here if you don't want to risk any spoilers.
Slate had a interesting interview with a real linquist who gave some insight into how different language structure words or thoughts. And a summary of what the plot means.
Apparently the aliens experience "nonlinear time." (I didn't get this this until I read about the movie afterward.) Their loops contains subsymbols that aren't necessary in a linear time order -- the aliens think about time cyclically instead of in a straight line. Slate: "As Louise [the lingust] learns the language, she also begins gradually experiencing visions of her future, a sign that she too is beginning to experience time differently."
I don't know what nonlinear time is. I don't see how it wouldn't violate causality. I don't see how the speed of light could be a constant in all reference frames, as we know it is. (Einstein assumed that as a postulate of special relativity, and by the accuracy of its predictions we take it now as a fundamental property of the universe.) If time is cyclic, couldn't you, in particular, travel from where you are today and when and come back to the same place and time? Or at least the same time? What then if you didn't do the same thing you did the first time? How can these aliens be just a few feet from humans and experience time so radically different?
That's just one thing that bothered me. The other is that, here are these aliens who managed to come here, en masse, from who knows where in the universe. They also know something about antigravity, or altering the direction of gravity, as the early parts of the show make clear; also their spaceships hang silently several meters above the ground.
So these beings know how to do all this, and we have to translate their language?? They can't translate ours? Nonlinear time presumably has linear time as its zeroth-order leading term, and but they don't understan that? They are clearly very intelligent compare to us, but they can't translate a simple linear language?
I didn't find that convincing. Of course, the plot hangs on the struggle to understand their language before Earth's countries try to bomb them to hell out of them (trivial for them to handle). Without that struggle, the plot would collapse into much less than it is, and probably not enough.
So in these senses the movie isn't exactly hard scifi -- it alters reality for the sake of its plot. Just when they started getting to the good stuff, they pull a deus ex machina. The fact that a lot of people needed the plot explained to them afterward shows this didn't really work.
Still, it's a movie well worth seeing.

Krugman Does It Again
And he has an almost school-boyish, smartest-kid-in-the-class aversion to ever being called wrong:
Trump was elected on 11/8. That night the Dow futures tanked, as did the Nikkei Index. But on 11/9 the S&P 500 went up 1.1% from its previous close. The next day it was up another 0.2%. At that point Krugman cried "uncle." Not very impressive.
But he's sure in the long run Trump will be a disaster. I'd like to think so too, but it's not clear to me at this point. Already he is showing signs of compromising his campaign promises -- on the wall, on the Affordable Care Act, on a Muslim ban, and on same-sex marriage.
Anyway, Krugman says Trump will bring "runaway climate change." If he means "runaway" in the scientific sense, a la Venus, he's wrong -- the Earth isn't close enough to the Sun to undergo such a runaway (but only by a few million km). Even if we burn all the fossil fuels available -- about 12,500 Pg carbon, according to Swart and Weaver 2012 -- we'd get 9 to 33 C of warming. Serious shit, but not runaway.
Maybe Krugman thinks Trump will keep us on RCP 8.5. Probably, but the world is on that anyway. Nothing the US can do individually to stop it, and I don't see the US killing the Paris agreement alone. If anything there might be some retaliation. I hope there is -- that's the best way to enforce a global carbon tax.

Callendar's 1938 Figure
Note Callendar didn't attribute all the temperature rise to CO2. I don't see in his paper (though I haven't read it carefully) where he considered possible changes in solar irradiance (or, for that matter, a reduction in volcanic cooling that was part of the Little Ice Age). But those would be small, perhaps just a few hundreths of a degree (climate sensitivity to changes in solar radiance is small, about 0.1°C/(W/m2), for solar radiance measured at the top of the atmosphere; see the IPCC 5AR).

The Dirt from Anthony Watts and His Blog
I predict Worrall's string of failures, shown below, won't change his inept and stubborn mind one bit.
"Everyone knows the Paris agreement was dead on arrival."

"It seems likely Lord Deben’s concerns about the Paris Climate Treaty are shared by other prominent green politicians."
- Eric Worrall, WUWT 3/9/16
"If the Paris Climate Agreement was already a joke, the Chinese electricity export plan is surely the punchline."
- Eric Worrall, WUWT 4/17/16
"Aussie academic David Holmes, of the University of Melbourne, suggests that Politicians are using the Paris Agreement to defuse climate concerns, by claiming Paris “solved” the climate crisis – and he’s not happy about it."
- Eric Worrall, WUWT 5/23/16
"The initial explosion of green Euphoria at the announcement of the COP21 climate agreement, is rapidly giving way to dismay, as various environmentalists and other expectant parties realise how feeble their climate “victory” really is."
- Eric Worrall, WUWT 12/15/15
"It’s been a few weeks since the U.N.’s Paris Climate Conference (COP21) ended. Mainstream media from around the globe praised the impotent agreement, as though anyone expects political promises to be kept. The COP21 agreement reminded me of the proverb A promise is a comfort for a fool."

When Bob Dylan Defended Zionism
Lyrics:
Neighborhood Bully
His enemies say he’s on their land
They got him outnumbered about a million to one
He got no place to escape to, no place to run
He’s the neighborhood bully
The neighborhood bully just lives to survive
He’s criticized and condemned for being alive
He’s not supposed to fight back, he’s supposed to have thick skin
He’s supposed to lay down and die when his door is kicked in
He’s the neighborhood bully
The neighborhood bully been driven out of every land
He’s wandered the earth an exiled man
Seen his family scattered, his people hounded and torn
He’s always on trial for just being born
He’s the neighborhood bully
Well, he knocked out a lynch mob, he was criticized
Old women condemned him, said he should apologize.
Then he destroyed a bomb factory, nobody was glad
The bombs were meant for him. He was supposed to feel bad
He’s the neighborhood bully
Well, the chances are against it and the odds are slim
That he’ll live by the rules that the world makes for him
’Cause there’s a noose at his neck and a gun at his back
And a license to kill him is given out to every maniac
He’s the neighborhood bully
He got no allies to really speak of
What he gets he must pay for, he don’t get it out of love
He buys obsolete weapons and he won’t be denied
But no one sends flesh and blood to fight by his side
He’s the neighborhood bully
Well, he’s surrounded by pacifists who all want peace
They pray for it nightly that the bloodshed must cease
Now, they wouldn’t hurt a fly. To hurt one they would weep
They lay and they wait for this bully to fall asleep
He’s the neighborhood bully
Every empire that’s enslaved him is gone
Egypt and Rome, even the great Babylon
He’s made a garden of paradise in the desert sand
In bed with nobody, under no one’s command
He’s the neighborhood bully
Now his holiest books have been trampled upon
No contract he signed was worth what it was written on
He took the crumbs of the world and he turned it into wealth
Took sickness and disease and he turned it into health
He’s the neighborhood bully
What’s anybody indebted to him for?
Nothin’, they say. He just likes to cause war
Pride and prejudice and superstition indeed
They wait for this bully like a dog waits to feed
He’s the neighborhood bully
What has he done to wear so many scars?
Does he change the course of rivers? Does he pollute the moon and stars?
Neighborhood bully, standing on the hill
Running out the clock, time standing still
Neighborhood bully

Again About the Word Denier
I was lead to the quote below from a New York Review of Books article about the recently released movie Denial, which is about the David Irving vs. Deborah Lipstadt and Penguin books trial in the UK in 2000.
Lipstadt had published a book in 1993, Denying the Holocaust, in which she called the British amateur historian David Irving “one of the most dangerous spokesmen for Holocaust denial.” Irving actually confronted her in the middle of a class lecture at Emory University, and went on to sue her and her publisher. But instead of sueing them in the US where the book was published, he filed his suit in the UK, where those who make potentially libelous remarks must prove they are true. The trailer is a good introduction to the film, which came out about three weeks ago.
Lipstadt's lawyers attacked Irving hard, simply on the facts, and made Lipstadt stay quiet during the proceedings. She, being Jewish, was more emotional about all of it because she considered herself to be defending her people, but her lawyers opted, no doubt correctly, that the case would be won on the facts and not on emotions.
This is from Irving's opening statement:
"The book purports to be a scholarly investigation of the operations of an international network conspiracy of people whom the Second Defendant has dubbed "Holocaust deniers." It is not. The phrase itself, which the Second Defendant prides herself on having coined and crafted, appears repeatedly throughout the work, and it has subsequently become embedded in the vernacular of a certain kind of journalist who wishes to blacken the name of some person, where the more usual rhetoric of neo-Nazi, Nazi, racist, and other similar epithets is no longer deemed adequate. Indeed, the phrase appears over 300 times in just one of the Defendants' experts reports!We Americans take free speech for granted, and it's easy for us to question German and French laws against denying the Holocaust. But I'm sure we have little idea of the paroxysms and spasms that shook German society, or Europe, after the war.
"It has become one of the most potent phrases in the arsenal of insult, replacing the N-word, the F-word, and a whole alphabet of other slurs. If an American politician, like Mr. Patrick Buchanan, is branded even briefly a "Holocaust denier," his career can well be said to be in ruins. If a writer, no matter how well reviewed and received until then, has that phrase stuck to him, then he too regard his career as rumbling off the edge of a precipice.
"As a phrase it is of itself quite meaningless. The word "Holocaust" is an artificial label commonly attached to one of the greatest and still most unexplained tragedies of this past century.
"The word "denier" is particularly evil: because no person in full command of his mental faculties, and with even the slightest understanding of what happened in World War II, can deny that the tragedy actually happened, however much we dissident historians may wish to quibble about the means, the scale, the dates and other minutiae.
"Yet meaningless though it is, the phrase has become a part of the English language. It is a poison to which there is virtually no antidote, less lethal than a hypodermic with nerve gas jabbed in the neck, but deadly all the same: for the chosen victim, it is like being called a wife beater or a pƦdophile. It is enough for the label to be attached, for the attachee to find himself designated as a pariah, an outcast from normal society. It is a verbal Yellow Star.
"In many countries now where it was considered that the mere verbal labelling was not enough, governments have been prevailed upon to pass the most questionable laws, including some which can only be considered a total infringement of the normal human rights of free speech, free opinion and freedom of assembly."
Irving's attack on the word "denier" appear pompous and bombastic (as he came across in person, too). I've never seen anyone hint that their use of it was akin to "being called a wife beater or a paedophile." I see it as a word, with a definition that predated the Holocaust, that has a certain meaning that conveniently and accurately describes the cruder blunt dismissals of anthropogenic climate change -- denying the greenhouse effect, the enhancing greenhouse effect, basic measurements, ridiculing and attacking scientists, always finding an excuse to dimiss the evidence one doesn't want to hear, etc. I suspect it comes more from a mindset than anything else -- some climate deniers seem to be conservatives who disagree with the general direction of the USA & World, a mindset that has infected the GOP in the age of the Internet, or just like being contrary.
Some people deny basic climate change; wilder ones deny the Sandy Hook shootings. A few crazies still deny the Holocaust. But if Irving was so upset about the word "denier," then clearly complaints about the word don't simply spring from a simaliarity to Holocaust denial but have an earlier origin, and those now using it aren't "global warming Nazi's," a rather ironic turn of phrase.
Irving, of course, played the victim, as you can read thoughout his opening statement. He lost the case, and, on appeal a year later, the case was dismissed.
After the trial, he was asked, "Will you stop denying the Holocaust on the basis of this judgment?" Irving replied, "Good Lord, no."

NASA: Hubble May Have Detected Water Plumes on Europa
It's not a definite discovery. They observed Europa transiting in front of Jupiter -- an idea from what's being done with exoplanets -- in the UV, and on 3 of 10 transits saw evidence of water vapor from water plumes off Europa's southwest limb:
It's the green flares at about five thirty to nine o'clock that represent the possible plumes. Seeing this evidence on three times out of ten means the plumes may be intermittent.
If true, this could be significant, because it means access to Europa's ocean -- which is global, saline and beneath miles of ice, and could potentially host life -- would be available near the surface, without having to drill through miles of ice (which, on a foreign moon, only looks easy in the movies).
Here's an artist's interpretation of one possible scenario:
I guess you could call these Europaean fistules. But plumes sounds better.
The surface tempeature of Europa is about -160 C (-260 F) at the equator and no higher than -220 C (-370 F) at the poles. So any water is going to instantly freeze. I guess the idea is to look for signs of life -- or at least organic compounds -- in the refrozen surface ice. Unless the plumes are huge and powerful, that's going to limit any detected life to microbes and not alien tuna.
Here's another scenario that was presented, expanding on one section above, which looks more amenable to finding tuna:
A paper is coming out soon in the Astrophysical Journal -- I'll try to remember to link to it.
The scientists said they were stretching Hubble's capabilities to the limit, so this isn't a definite discovery, and they "remain cautious."
Finally, here's another image that was presented, with a self-explanatory caption:

Latest on the Not-Happening La NiƱa
NASA’s Goddard Space Flight Center say there is unlikely to be a La NiƱa event in late 2016.We may be stuck with this El Nino warmth after all -- NOAA just posted the warmest August in their records, which go back to 1880. Warmer (more anomalous) than May 2016, or June '16 or July '16.
In fact, every month since May 2015 is the warmest in the record. 16 straight months now.
At this point we really have to start asking, not if AGW is true, but is it accelerating, and if so, by how much?
Deep Ocean Warming: How Much?
You can read the abstract here, but deep ocean heating is only about 1/10th of total ocean heating. I guess we'll know more when deep Argo comes out, which I suspect will reduce the error bars significantly. Not sure when that will be, though.
Remember, it's only been since 2005 that Argo has been measuring the temperature and salinity of the top half (< 2000 m) of the ocean. If deep Argo happens by, say, 2020, that will be an amazing achievement -- because ocean heat content is by far the best way to measure the global energy imbalance that causes global warming.
Can 375 Great Scientists Correct Donald Trump on Climate Change?
But still, yesterday 375 members of the National Academy of Science published a letter saying
Human-caused climate change is not a belief, a hoax, or a conspiracy. It is a physical reality. Fossil fuels powered the Industrial Revolution. But the burning of oil, coal, and gas also caused most of the historical increase in atmospheric levels of heat-trapping greenhouse gases. This increase in greenhouse gases is changing Earth’s climate.
...During the Presidential primary campaign, claims were made that the Earth is not warming, or that warming is due to purely natural causes outside of human control. Such claims are inconsistent with reality.That's a good, strong phrase -- "inconsistent with reality."
The letter isn't addressed to anyone specific, but it's said to be directed at Donald Trump.
Unfortunately, Trump shows little interest in knowledge, and I doubt this is going to change his climate idiocy, even if he is elected.
I doubt Trump has the guts to do this, but a few of these scientists should get together and offer to go to Trump and, in one hour, present him the evidence behind manmade climate change. Like those brave scientists did for the governor of Florida. Publicize the hell out of the offer, and, if it happens, of the followup.
As it is, I wonder if a single debate moderator -- who think they are "journalists" -- is going to ask a single question of either presidential candidate about the most important topic of the 21st century.
Unfortunately, the moderators of the first debate have announced their topics, and it looks to be the usual network fluff that makes intelligent people want to vomit.
Anyway, so who do we know? Well, for me, a lot of scientists I know and/or have interviewed and/or recognize and respect a great deal. (I'm always surprised at how many great scientists I don't know, like when it comes to the Nobel Prize announcements or NAS inductions):
Personally I think Adam Riess ought to run for President. He's young, well spoken, and really smart. Just what the American people are looking for, right?
Right?
