Is it a myth that "Road Warrior" has subtitles in American English, where "Road Warrior" is the 1st version of "Mad Max 2: Road Warrior" in cinemas in the United States of America (where it had not been presented as a sequel to "Mad Max", which supposedly had not yet been released in the U.S.A.)?

It is not a myth that I in the West did watch English subtitles on TV of a non-"Road-Warrior" video of a man speaking in Australian English. These subtitles are for all viewers (i.e. not just persons who cannot easily hear). They are not for a comedic effect.

A teacher in the United States of America wrote to the SciFraud LISTSERV (Discussion of Fraud in Science): |-----------------------------------------------------------------------------| |"Dewey, | | I feel bad that I put you in a not-so-cheerful mood. Some explanation is | |necessary. | | | | >What are you trying to state, or imply, in this message? That you | |caved in to parental pressure, and GAVE a mediocre student an "A" grade?< | | | | I was threatened and intimidated by these people. Despite what I value as | |a strong sense of integrity, I was going to give the girl an A. I have a | |family to support. I mentioned that story to point out that I was prepared to| |fudge the grade for my own self-preservation and that the existence of | |conditions which would actually favor the parent in this situation, should | |not exist. It has become so common for parents to browbeat teachers, with the| |support of their local school boards, that most teachers wouldn't dare to | |challenge the system by setting standards which would make them stick out | |like a sore thumb. | | When I first started teaching, I heard a principal challenging a teacher | |because his students got almost all A's and B's in his classes. About ten | |years later, I heard a principal criticize a teacher for giving too many D's | |in a gifted and talented class. This was the consequence of parental | |pressure. Times had changed quickly. Two years ago, I asked the principal why| |a legal absence is given to a student who took four days extra vacation and | |didn't even have the required note prior to the absence. He responded by | |telling me the absence was legal because he said so. These things happen | |constantly. When students start their summer vacations two or three days | |before the end of the school year, we are specifically instructed to | |calculate the student's grade on the basis of the work possible as of the | |time of the student's departure. No extra work has to be submitted. | | So yes, as a matter of confession, and one of which I am not proud, I was | |afraid to give the student anything but an A when the parents threatened to | |have my job. For two years, our principal published grade stats by | |department, making sure to commend those with the highest grades for being | |the most successful teachers. He announced at a parent back-to-school meeting| |that the goal for the year was "success for all students at all times." I was| |probably the only teacher who really listened to this and I was extremely | |stressed out at the implications of how such a thing could be achieved. | | My story was not to support the notion of grade inflation. I was, in a | |self-effacing way, pointing out how I, as a teacher, have been a victim of | |the trend. Furthermore, I know that the principal has the authority to order | |me to change a grade or suffer disciplinary action for insubordination, | |ultimately ending with his authority to change the grade anyway. (BTW, this | |wasn't a high schooler, it was a sixth grader in Technology Education, | |formerly Industrial Arts.) What I didn't say is that the student's B was | |largely due to the fact that she had not completed a major project. After I | |got roasted and was clearing out the room after students had left for the | |summer, I found the part of the girl's project which had been missing. She | |had put it in the wrong place. One simple step now, and the project was | |finished. The missing part was an assembly which constituted most of the | |work. Fortunately, I didn't have to lie about her grade, but I am pretty sure| |I would have. | | | |>And that their current difficulties must be the fault of the | |university professor--because they KNOW that they are "A" students. Because | |their high school teachers said so.< | | | | The girl was an excellent student. She had always made straight A's. I | |know this doesn't mean as much as some would like it to. I also know that my | |subject can often be inconsistent with other grades, either to the student's | |advantage OR disadvantage. Most parents realize how different my subject is, | |especially for 6th graders, and usually accept that as an explanation for an | |unexpected grade. Some students are successful in school, not so much because| |of their raw intellectual ability, but more because of their ability to | |conform and anticipate. The methods and activities in my subject do not | |follow the format to which many of these children have become accustomed. | |Some weaker students benefit from this and some stronger students have | |trouble making the adaptation.

We had a monstrous winter storm and a deadly avalanche near Truckee recently.

This morning, the freeway near here (in Sunny California) was shut down from black ice. The US northeast has had unprecedented cold... ask Phil about that.

Cold kills.

TDS isn't healthy either.

There are easy ways around that, but you'd have to take lessons in being nice.

Be nice. Give it a try.

Yes, it's been (brr) cold here. We had about 10 inches of that damn global warming fall on us 3 weeks ago, and another potentially significant snowstorm is predicted for NYC this weekend. (I'm roughly

20 miles from both Phil and NYC)

Anthropogneic global warming has already raised sea surfaces temperatures by more than one degree Celcius over pre-industrial levels. That 10% more water vapour in the air above the oceans, and 10% more energy to drive extreme weather events. The average temperature is up a bit, but the extremes are covering a wider span. Temperatures extremes at either end of the range do kill people

Not a appreciating how much damage Donald Trump is doing is the real Trump derangement syndrome. You are suffering from a bad case of it.

Where would that energy have gone otherwise?

The pre-industrial baseline was the Little Ice Age. People ice skated and had winter faires on the Thames.

Presumably radiated back into space.

But computer simulations are cheap and very cooperative.

Apparently the few giant dram and flash makers are *not* ramping up capital investment and production to meet the AI demand, but raising prices and assuming that AI will mostly crash.

That's sound business planning.

I just bought a couple of laptops

and was surprised at the price. They seem to be pretty good. One is for a student at Cal Poly who will help us with an FPGA design. We bought him a scope too.

That's amazing, 4 channels at 250 MHz and a decent signal generator.

It can't do 50 ohm inputs and comes with 2 probes, but that's easily fixed.

The "Little Ice Age" seems to have been restricted to the areas around the North Atlantic. The north Atlantic multidecadal osciilation seems to have had something to do with it. Meandering ocean currents in other regions have produced similar effects at different times.

Sea surface temperatures averaged over the whole world are more stable, but wandering ocean currents introduce some low frequency noise.

The global monitor - going back about a million years - are isotope ratios in the Antarctic ice cores. The climate change denial propaganda you recycle here isn't aimed at sophisiticated readers.

Obviously into warming the oceans even more. This decreases the amount of CO2 they can take up, but since CO2 levels in the atmosphere are going up a lot faster than the oceans are warming up, this is a long term problem. At the moment about half the extra CO2 we are emitting ends up in the oceans

Some of it is re-radiated back into space.

The sort of computer simulation that models the planet as a whole isn't cheap, and not in the least cooperative.

IEEE Spectrum ran an article "cloud computing" a few years ago on the difficult to making climate simulations fine-grained enough to model cloud cover. Apparently the then current state of the art worked with tiles about 100 miles by 100 miles, and cloud cover was averaged over the entire tile. The ambition was to get down to cloud sized tiles, but that was someway off.

That's wishful thinking. It always easier to do nothing and raise your prices. AI isn't wildly useful, but it does seem to work well enough that people with use it, if mainly to make plausible propaganda aimed at gullible twits like you. That's a mass market. People who do gear up to cater for it will make money - if almost certainly not as much as the stock market currently seems to think. The dot com bubble wasn't a bubble because international communications didn't take off, but because they didn't take off quite as fast as people had hoped.

<snipped the boasting about some new toys>

A wam ocean leads to more cloud cover which reflects more energy into space which reduces the overall energy input from the Sun. Sounds as though the system might be stable in the long term.

It doesn't. Clouds form in rising air as it cools and dissipate when the same air hits the tropopause and starts falling and getting warmer. Cloud cover pretty much has to be stable at 50%.

If you have a multilayer atmosphere it gets more complicated, but we don't.

It wasn't stable enough for the last couple of million years to stop us flipping between ices ages and interglacials, and there was an episode of natural methane release about 55.8 million years ago

formatting link
when global temperatures went up by between 5 and 8 degree Celcius for about 200,000 years. The methane turned into CO2 pretty rapidly, so it's a good model for out anthopogenic global warming.

The initial rate of carbon injection back then was slower than what we've achieved recently - the initial temperature rise took about ten or twenty thousand years.

The system wasn't stable back then, and it's a bit optimistic to think that it might be more stable now. People who make a lot of money out of digging up fossil carbon and selling it as fuel are naturally more optimistic, and want the rest of us to share their unrealistic optimism.

Pretty obviously we have negative feedbacks, otherwise we'd be Venus.

The AGW industry has to invent and simulate positive-feedback tipping points. Their funding depends on it.

The dot.com bubble was driven by absurd amounts of money invested in way too many idiotic ideas. Read

great fun.

There's a part of San Francisco that used to be quiet, a mix of old brick factories and Victorian houses. It's called The Arena now, rents are crazy, and parking is impossible. All because of AI.

My wife has her speech therapy office in a big building with a lot of small units. It used to have a lot of hair stylists and tattoo salons and artists and units available to rent, with lots of space in the parking garage. Now it's jammed with AI geeks and here's no parking available. This has got to crash.

If AI is so good, why would any AI company need more than four employees?

I'm not boasting. Anybody could buy these things, even you.

Of course thare are negaive feedbacks. First, as temperature grows Earth emits more heat radiation. This grows with fourth power of temperature, so it is pretty strong effect.

But you ignore simple thing: system with negative feedback and delay will oscilate. And there are a lot of delays in the system. There is also a lot of nonlinearties. When you gradually turn on power to an oscilator it will probably not surprise you that with growth of supplay voltage you get bigger amplitude of oscilations on the output. Depending of details it would not surprise me seeing negative peaks going lower with bigger voltage. Yet, when you see oscilations in natural system you act as you never saw an oscilator.

Concerning limits, I do not think Venus-like scenario is possible for Earth. But having Carbon again wound be very hard for people. Tropical areas probably would be inihibitable by humans in such a case. There would be disastrous impact on agriculture: plants that we know how to handle and which we selected over thousends of years would be badly adapted. Antarctica would melt signifcantly reducing habitable land. More energy in atmosphere means strongee winds, torndoes, flooding etc. Our current architecture is build on certain assumptions about climate, with changed climate many current buildings will be destroyed and we will need new ones.

It is not clear to me if attemps to stabilize temperature at level as it was 100 years ago is wise. Namely there are natural variations and fighting natural change may take too much effort. But our current impact is larger than natural variations on similar time scale and without global climate control policy will grow.

Of course, so people want to be "free riders", that is collect benefits but let the other do the work. This seem to be current US policy. And of course much of business works on principle "get money now", leaving troubles to government and future generations. Of course, there is hipocrisy too: European governments are much less eager to adapt electric cars now, when it turned out that Chinese ones are better than European ones.

But believing that nothing serious is happening to climate is just ignores solid data (which a lot of politicians like to do).

I design stable high-order negative feedback systems. Mine don't oscillate.

Plants love CO2. Veggies are grown in hothouses at 1000 PPM of CO2.

In past times, when life flourished on earth, CO2 was 5000 PPM.

Plants are near starving now. I'm thinking that something like 700 PPM would be good.

Comparing temps to "pre-industrial times" clearly has instrumentation hazards. We are taking millions of times more measurements than we did in 1800.

We're lucky to be living in an interglacial. What will be serious is the next ice age.
