SMPTE color bars – Click for your own test pattern kit

This page is for posters to test comments prior to submitting them to WUWT. Your tests will be deleted in a while, though especially interesting tests, examples, hints, and cool stuff will remain for quite a while longer.

Some things that don’t seem to work any more, or perhaps never did, are kept in Ric Werme’s Guide to WUWT.

Formatting in comments

WordPress does not provide much documentation for the HTML formatting permitted in comments. There are only a few commands that are useful, and a few more that are pretty much useless.

A typical HTML formatting command has the general form of <name>text to be formatted</name>. A common mistake is to forget the end command. Until WordPress gets a preview function, we have to live with it.

N.B. WordPress handles some formatting very differently than web browsers do. A post of mine shows these and less useful commands in action at WUWT.

N.B. You may notice that the underline command, <u>, is missing. WordPress seems to suppress for almost all users, so I’m not including it here. Feel free to try it, don’t expect it to work.

Name Sample Result
b (bold) This is <b>bold</b> text This is bold text
Command strong also does bolding.
i (italics) This is <i>italicized</i> text This is italicized text
Command em (emphasize) also does italics.
a (anchor) See <a href=http://wermenh.com>My home page</a> See My home page
A URL by itself (with a space on either side) is often adequate in WordPress. It will make a link to that URL and display the URL, e.g. See http://wermenh.com.

Some source on the web is presenting anchor commands with other parameters beyond href, e.g. rel=nofollow. In general, use just href=url and don’t forget the text to display to the reader.

blockquote (indent text) My text

<blockquote>quoted text</blockquote>

More of my text

My text

quoted text

More of my text

Quoted text can be many paragraphs long.

WordPress italicizes quoted text (and the <i> command enters normal text).

strike This is <strike>text with strike</strike> This is text with strike
pre (“preformatted” – use for monospace display) <pre>These lines are bracketed<br>with &lt;pre> and &lt;/pre>
These lines are bracketed

with <pre> and </pre>
Preformatted text, generally done right. Use it when you have a table or something else that will look best in monospace. Each space is displayed, something that <code> (next) doesn’t do.

See http://wattsupwiththat.com/resources/#comment-65319 to see what this really does.

Youtube videos

Using the URL for a YouTube video creates a link like any other URL. However, WordPress accepts the HTML for “embedded” videos. From the YouTube page after the video finishes, click on the “embed” button and it will suggest HTML like:

<iframe width="560" height="315"


        frameborder="0" allowfullscreen>


WordPress will convert this into an internal square bracket command, changing the URL and ignoring the dimension. You can use this command yourself, and use its options for dimensions. WordPress converts the above into something like:

[youtube https://www.youtube.com/watch?v=yaBNjTtCxd4&w=640&h=480]

Use this form and change the w and h options to suit your interests.

Images in comments

If WordPress thinks a URL refers to an image, it will display the image

instead of creating a link to it. The following rules may be a bit excessive,

but they should work:

  1. The URL must end with .jpg, .gif, or .png. (Maybe others.)
  2. The URL must be the only thing on the line.
  3. This means you don’t use <img>, which WordPress ignores and displays nothing.
  4. This means WordPress controls the image size.
  5. <iframe> doesn’t work either, it just displays a link to the image.

If you have an image whose URL doesn’t end with the right kind of prefix, there may be two options if the url includes attributes, i.e. if it has a question mark followed by attribute=value pairs separated by ampersands.

Often the attributes just provide information to the server about the source of the URL. In that case, you may be able to just delete everything from the question mark to the end.

For some URLs, e.g. many from FaceBook, the attributes provide lookup information to the server and it can’t be deleted. Most servers don’t bother to check for unfamiliar attributes, so try appending “&xxx=foo.jpg”. This will give you a URL with one of the extensions WordPress will accept.

WordPress will usually scale images to fit the horizontal space available for text. One place it doesn’t is in blockquoted text, there it seems to display fullsize and large images overwrite the rightside nav bar text.

Special characters in comments

Those of us who remember acceptance of ASCII-68 (a specification released in 1968) are often not clever enough to figure out all the nuances of today’s international character sets. Besides, most keyboards lack the keys for those characters, and that’s the real problem. Even if you use a non-ASCII but useful character like ° (as in 23°C) some optical character recognition software or cut and paste operation is likely to change it to 23oC or worse, 230C.

Nevertheless, there are very useful characters that are most reliably entered as HTML character entities:

Type this To get Notes
&amp; & Ampersand
&lt; < Less than sign

Left angle bracket

&bull; Bullet
&deg; ° Degree (Use with C and F, but not K (kelvins))








Superscripts (use 8304, 185, 178-179, 8308-8313 for superscript digits 0-9)




Subscripts (use 8320-8329 for subscript digits 0-9)
&pound; £ British pound
&ntilde; ñ For La Niña & El Niño
&micro; µ Mu, micro
&plusmn; ± Plus or minus
&times; × Times
&divide; ÷ Divide
&ne; Not equals
&nbsp; Like a space, with no special processing (i.e. word wrapping or multiple space discarding)
&gt; > Greater than sign

Right angle bracket

Generally not needed

Various operating systems and applications have mechanisms to let you directly enter character codes. For example, on Microsoft Windows, holding down ALT and typing 248 on the numeric keypad may generate the degree symbol. I may extend the table above to include these some day, but the character entity names are easier to remember, so I recommend them.

Latex markup

WordPress supports Latex. To use it, do something like:

$latex P = e\sigma AT^{4}$     (Stefan-Boltzmann's law)

$latex \mathscr{L}\{f(t)\}=F(s)$

to produce

P = e\sigma AT^{4}     (Stefan-Boltzmann’s law)


Linking to past comments

Each comment has a URL that links to the start of that comment. This is usually the best way to refer to comment a different post. The URL is “hidden” under the timestamp for that comment. While details vary with operating system and browser, the best way to copy it is to right click on the time stamp near the start of the comment, choose “Copy link location” from the pop-up menu, and paste it into the comment you’re writing. You should see something like http://wattsupwiththat.com/2013/07/15/central-park-in-ushcnv2-5-october-2012-magically-becomes-cooler-in-july-in-the-dust-bowl-years/#comment-1364445.

The “#<label>” at the end of the URL tells a browser where to start the page view. It reads the page from the Web, searches for the label and starts the page view there. As noted above, WordPress will create a link for you, you don’t need to add an <a> command around it.

One way to avoid the moderation queue.

Several keywords doom your comment to the moderation queue. One word, “Anthony,” is caught so that people trying to send a note to Anthony will be intercepted and Anthony should see the message pretty quickly.

If you enter Anthony as An<u>th</u>ony, it appears to not be caught,

so apparently the comparison uses the name with the HTML within it and

sees a mismatch.

I just had another thought about underlines.
I think I discovered that if I could get around the automatic spam trap by writing Anthony with an empty HTML command inside, e.g. Ant<b></b>hony .
What happens when I try that with underline?
Apologies in advance to the long-suffering mods, at least one of these comments may get caught by the spam trap.

I remember seeing this test pattern on TV late at night after the National Anthem and before the local station broadcast came on early in the morning while the biscuits, bacon and oatmeal were still cooking. The first show after a weather report was “Dialing For Dollars” and you had better know the count when your phone rang…. 1 up and 3 down… to get the cash.

I have been looking for a way to create a table.
How did you do it?

He used the <pre> command, it’s described in the main article. Pre is for preformatted text and displays in monospace and with all the spaces preserved.

WordPress only displays images for URLs on their own line and ending with a image file extension. If I delete the attribute string above, i.e. ?token=I7JQbQli1swRgik%2BKnIKAmCk52Y%3D then what’s left should work:

Here’s an image that I think has never been displayed by WP, with a suffix that in the past would prevent WP from displaying an image:

Now one that would permit image display:
Update: Right clicking to get the image’s url gave me a URL that goes through WP’s cache via (slashes replaced by spaces, periods by dashes) i2-wp-com wermenh-com images winter0708 P3020227_snowbank7-jpg

Now just the image without a suffix:
Update: This image uses the same URL as the previous cached image. That means we can’t use a changing suffix to force a trip around the cache any more for HTTP images. I’ll play with HTTPS later.

Is there something wrong with latex support on the test page?

Error in the third line can’t use \\ in the latex code.
m_{H2O} \propto A_{surface}
E_{total} \propto \int_{A_{surface}}FdA \mbox{(where } F \mbox{ is the flux in watts per square meter)}
dT \propto \frac {E_{total}}{m_{H2O}}

Owen in GA

E_{total} \propto \int_{A_{surface}}FdA \mbox{(where } F \mbox{ is the flux in watts per square meter)}
a mistake in this line maybe?

Owen in GA

The first two lines
m_{H2O} \propto A_{surface}
E_{total} \propto \int_{A_{surface}}FdA \mbox{(where } F \mbox{ is the flux in watts per square meter)}
Will they show?

Owen in GA

\frac{\partial T}{\partial t} = \frac{\int_{SA}FdA}{SA \times d \times \rho} \times \frac{\partial T}{\partial Q} =\frac{F \times SA}{SA \times d \times \rho} \times \frac{\partial T}{\partial Q} =\frac{F}{d \times \rho} \times \frac{\partial T}{\partial Q}

Yep, they’re the same.

Reply to Ric W ==> Thanks — I was fielding comments on an essay using an unfamiliar tablet, and wasn’t sure which and/or both were part of HTML5. I usually use the old ClimateAudit comment Greasemonkey tool, even though its formatting is funky these days, for the tags. Don’t suppose you could update that add-in?

IIRC, Greasemonkey was written for CA, which uses a different theme that does WUWT.
I don’t have the time to figure out the JavaScript code or whatever it’s written in, and I don’t have the ability to make changes that deep in WUWT.
Instead of Greasemonkey, I often use https://addons.mozilla.org/en-US/firefox/addon/its-all-text/ . It can open up an external editor, so it has saved my butt a few times when WP loses a post I was making.

Hey, what happened to the old smiley face?? When I tried to post it, this appeared:

I wonder if WordPress changed any others?
 ☹ ☻
The old smiley was more subtle; less in-your-face. The new one is way too garish.
If WP keeps that up, I’ll just have to use this lame replacement:
Or even worse:

The old ways are the best ways! 🙂

“Trenberth’s calculation is very simple. It just multiplies the world’s average rainfall (about 900 mm/yr) by the latent heat of evaporation. Do you think the basis is wrong? Or the rainfall is underestimated”

The calculation may be simple but the issue clearly isn’t! Just the thought of the “Pan Evaporation Paradox” and the countless papers attending to it, make it clear that the issue is far from simple; but isn’t that the heart of the criticism of it here!
It is not very hard to see, that “the basis is wrong” and that “rainfall is underestimated”!
As for the basis, you are making the argument – for Trenberth – that evaporation is the only way to get H2O (In any or all its phases) into the atmosphere, are you not.
Now I’m immediately thinking how it can** and to quote the poet – “Let me count the ways”! 😉
Speaking of numbers, there are approximately a “gazillion” 😉 papers that have been peer reviewed and published in the last century on what is arguably the single most important “way”.
Known to the layman as sea spray it is technically called “entrainment”. And this contribution from the ocean atmospheric boundary layer under windy conditions is well know and understood to be huge!
Huge enough, that it “is necessary to take into account storm-caused enhancement of the energy and mass transfer through the ocean surface when constructing climate models and models of general circulation of the atmosphere and ocean, and also when devising methods of long-term weather forecasting.” (Dubov), (Marchuk).
So, we have according to a vast body of literature* that via this mechanism: “even during a brief stormy period, the ocean is able to deliver to the atmosphere enormous amounts of extra heat and moisture, which can alter substantially the state of the atmosphere over vast regions.” (R.S. Bortkovskii)
And the key here, is that it is kinetic energy that delivers the water vapour to the atmosphere and not the latent heat of evaporation (The temperature of the boundaries determines how much heat is also exchanged but vaporisation is not dependant on the relative temperatures). Additionally, regarding this heat flux:
“When the air temperature is quite low (in high latitudes, for example) the spray sensible heat flux can be roughly as large as the spray latent heat flux. In temperate and tropical latitudes, however, the spray latent heat flux virtually always dominates the sensible heat flux. The magnitude of this flux can be quite large. In a 20-m/s wind, in low latitudes, a typical magnitude for the spray latent heat flux is 150 W/m(squared), which is the same order of magnitude as the interfacial latent heat flux.
Now on a personal note and at the risk of sounding Willis-like, I came across one of the “other ways” while in Zermatt Switzerland! Last year, in the European Alps, I observed and photographed a well known phenomenon, powder snow blowing off the high peaks and forming cirrus clouds:
Later, in the Dolomites of Italy at altitude again, I met a meteorologist measuring ice core temperatures and we discussed my observation. It wasn’t at all new to him that water vapour in the atmosphere could find its way there independently of the latent heat of evaporation!
There is much more to this but it it is now very late in a very long day!
*See Edgar L Andreas, 1992, Sea Spray and Turbulent Air-Sea Heat Fluxes
**Wind! Think, the Southern Ocean and The Roaring Forties. It’s as good or better than insolation or LWIR!
Every turbulent stream rapid or waterfall on earth that did or didn’t cast a rainbow.
Geothermal (Think, magma meets water/ocean… since time began!)
Storms, cyclones and tornadoes of course and waterspouts at sea – observed much in my youth – that suck up ocean water and anything in it. (My good friend’s ship got hit by one and it disgorged a tonnage of water. And here in Australia, in my lifetime there have been two occasions when fish fell from the sky – along with precipitation – many miles inland!;-)

It’s all evaporation. And it all takes heat from the surface and transports it (as LH) to higher altitude.

No Nick, even Trenberth admits that the points I’ve raised are worthy of ongoing study. Latent heat is not the only and singular path for water vapour in the atmosphere! And for what it’s worth, I have read his infamous papers!


Talk about Ozploitation!
This toilet paper has got to go down in history as the finest example of political talking points parading as science, ever written.
It is so dumb it’s not even wrong!
For a start, at the time humans arrived, Australia’s inland was covered by vast mega lakes – the remains of the Eromanga Sea:

…the environment was already changing by the time the first Australians arrived. The overflowing mega-lakes of pre-50,000 years ago had begun to shrink, and reliable supplies of freshwater were in a state of collapse.

The point is, humans arrived at a time of lowering sea level when the inland was a drying sea. From that time to the present date the inland extent actually expanded while sea levels slowly rose, enough to inundate the shallow land bridge but not the – below sea level – basins of the outback!

These inland mega-lakes were fed by big rivers such as Cooper Creekand the Diamantina River, which pumped large volumes of water into the continental interior every year to fill the lakes to the levels shown by the position of their ancient beaches. Mega-Lake Eyre held roughly ten times the water volume achievable under today’s wettest climate, and if present now would rank among the ten largest lakes (in area) on Earth. This truly was the inland sea that proved so elusive to Charles Sturt and other 19th-century colonial explorers.

It is interesting to note:
“To the surprise of the early mariners who explored Australia’s coastline none of them discovered the mouth of any great river. Consequently, explorers including Flinders, Banks, Oxley, Sturt and King, all assumed that rivers flowing inland from the Great Dividing Range must flow towards an Inland Sea (Flannery 1998, 226; Johnson 2001, 21).”
They never found the Sea but a huge body of water still exists today, not on the surface but hidden beneath: The Great Artesian Basin.
“The basin occupies roughly the same area as the Eromanga Sea, the major portion of the water flowing slowly underground from the Great Dividing Range in north Queensland towards South Australia.”
* “Species-specific responses of Late Quaternary megafauna to climate and humans”: Nature 479, 359–364 (17 November 2011) doi:10.1038/nature10574

Talk about natural climate variation, Lake Eyre fills only intermittently today:

Minor Flooding: Up to 2 m water covering half the lake: once in 3 years.
Major Flooding: Up to 4.5 m water covering all 8,000 [km.sup.2] of the lake: once in 10 years.
Filling: Filling another 50 cm: 2-4 times per century.
Great Filling: More than 5 m water: 2-4 times per millennium. (Kotwicki 1986)

“Odyssey from Africa (and the Adventures of Ipiki)” is an epic narrative poem telling the story behind the 60,000 years-ago exodus of modern humans from Africa that populated the rest of the world.

Yes, and this theory aligns with the measured data!
This post also highlights a feeling I’ve had for some time, that both sides are going out of their way to avoid discussing the Pan Evaporation Paradox.
I think it is because they all have a dog in the game. The data is disruptive because the cause doesn’t have to be explained for the damage to be done and a number of precious theories have been struck a mortal blow!

If climate is warming, a more energetic hydrologic cycle is expected implying an increase in evaporation. However, observations of pan evaporation across the U.S. and the globe show a decreasing trend in pan evaporation. – J.A. Ramirez, Colorado State University

And it doesn’t matter where it is measured – wet or dry, desert or tropics, the trend has been down for 68* years to date!
*For 50 years(1950-2000) the trend was sharply down, before a slight recovery 2000-2010 but sharply down again since then(Back to the near lowest levels of 1993).


Are These Coal Plants “tripping off” because of over heating?
It seems like news reports are written in a way that suggest that the coal plants are overheating. Poster benben seems to think similarly. The second quote below indicates the media suffers from lousy standards of clarity in it’s reporting.
For example:

The Australia Institute, which has documented the coal outages this year and produced a report on the intermittency of coal generators, argues that there should be a reliability obligation for coal and gas plants.
The report found that over the month of February in 2017, 14 per cent (3600MW) of coal and gas electricity generation capacity across the NEM failed during critical peak demand periods in three states as a result of faults, largely related to the heat.

A certain irony in this context of the idea of a “reliability obligation”!
Refers to a report by the Energy Security Taskforce.
The report was commissioned by the NSW government to examine risks to the resilience of the state’s electricity system after it came under pressure on in February during a late summer heatwave, when four major coal and gas units failed in the heat.
The incident, on February 10, 2017, saw the state narrowly escape a major, grid-wide outage when the capacity of available large thermal generators fell by about 805MW during the peak demand period, largely due to high ambient temperatures and cooling pond temperature limits.
“Risks from extreme weather are likely to continue to increase and test the resilience of the (NSW) system”, the report says. “Large coal thermal plant generally will not perform as well in extreme hot weather and can also have output limited by environmental constraints, for example, cooling pond temperature limits.”
A reasonable working theory is:
I1) A failure of all the recent Assie administrations to deal with the conditions of the climate that we have now and have had for some decades if not the entire history of the Australian electrical grid.
2) That politicians and campaigners can point fingers at coal plants and warming is a bonus in a game of denial and diversion.
A missing piece of the data are the recent trends in summer electricity demands.


It doesn’t if you take the full Mauna Loa CO2 data series and the HadCRU4 temperature series. By using the satellite era you don’t include part of the 1945-1975 period where temperature went down while CO2 went up.
Either you match the slopes or you match the amplitudes, not both at the same time.


Fascinating. I see not one, but three subduction zones near the northern and eastern borders of Bangladesh.comment image
Also this from wikipedia about the effects of the 2004 Indian Ocean Earthquake:

“There was 10 m (33 ft) movement laterally and 4–5 m (13–16 ft) vertically along the fault line. Early speculation was that some of the smaller islands south-west of Sumatra, which is on the Burma Plate (the southern regions are on the Sunda Plate), might have moved south-west by up to 36 m (120 ft), but more accurate data released more than a month after the earthquake found the movement to be about 20 cm (8 in).[38] Since movement was vertical as well as lateral, some coastal areas may have been moved to below sea level. The Andaman and Nicobar Islands appear to have shifted south-west by around 1.25 m (4 ft 1 in) and to have sunk by 1 m (3 ft 3 in).[39]”
