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.
code (use for monospace display) <code>Wordpress handles this very differently</code> WordPress handles this very differently
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:

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.

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! 🙂

Ah, some buglets appear to be invariant over years.


Wait what? (I’m trying underline) … but if it doesn’t work, how didi you?


$ latex \frac{100}{20} = 5 $


P = e\sigma AT^{4}


I’m at loss, why that works.


$ latex {10}^{-7}$ Finally right way to get an exponent?
$ latex {1010}_{2} = {10}$


$ latex {10}^{7}$


$ latex {10}^{4}$


$ latex {10}^{-7} $ Space added before ending dollar sign


$ latex {10}^{7} $


$ latex {10}^{4} $ 10⁴ 10⁷


Am I daft or why I didn’t get this already. Does it depend on newlines?
$ latex {10}^{7}$


One last try, then I’ll go and take a beer.
$ latex \frac{100}{20} = {5} $


$latex \frac{100}{20} = 5

In my previous post I use the example of the following over the next 100 years: 3 units of new energy goes to the oceans and 1 unit to the atmosphere – with all 4 units being equal in Joules. 1 unit raises the average temperature of the atmosphere by 4C or the average temperature of the oceans by 0.0003C. In this example the atmosphere warms by 4C and the oceans warm by 4 x 0.0003C or 0.0012C. It is exactly the higher heat capacity you mention that allows the heat energy to be absorbed with less movement of temperature. At the detail level maybe the top 2 inches of water gets much hotter and this will then support the physics of the more complex mechanisms you mention. But the beauty of this approach (I think – and hope) is that it doesn’t really matter how the energy gets distributed in the water with its corresponding temperature effect. Determine the mass of the ocean water you want to see affected in this model and apply the energy to it to get the temperature you would expect.

Is anyone using CA Assistant? I was using it before the migration — doesn’t work in current version and I can’t figure out why.

IIRC, I think it was written for Climate Audit and only accidentally worked here. It may be broken for good. The ItsAllText add-on may also be broken in newer Firefoxes.

Ric ==> CAsst had code that allowed it to function on Climate Etc, Climate Audit, WUWT and several others. The code was editable by the end-user to add additional sites using the standard WP format.
Still works on Judith’s site.
It is the shift to the new WP structure that has broken it.
Any hot coders out there? CA Asst is editable in Firefox with GreaseMonkey.

Is it because the “time stamp” is located at the end of the comment (at lower right-hand corner)?

We have the same issue. Does adding &xxx=foo.jpg help?

comment image


dropbox and many other image repositories use URLs that end in .jpg but return HTML. If you click on the above, you’ll see the image – but with a lot of WWW stuff around it. However, if you right click on the image, that will let you save a URL that may or not go to the .jpg, i.e.:

comment image/EOfmmrcEGLYHIAIoAg/vTZGXx1cnr1itCF7Quz5Y3b5dgdK_Ko-47O5lMJLmAk?dl=0&size=1280×960&size_mode=3

If I delete the trailing /EOfmmrcEGLYHIAIoAg/vTZGXx1cnr1itCF7Quz5Y3b5dgdK_Ko-47O5lMJLmAk?dl=0&size=1280×960&size_mode=3 , then I have a URL that might be a .jpg:

comment image

No, that trailing piece is important. If I use the full URL and append xxx=foo.jpg (no need for the “?” since there was one), I bet it won’t parse the full URL.

At this point, I don’t know how to display an image from Dropbox.

Oh wow – I’m very surprised.

I maintain this this page, part of the task is to trim people’s tests when they are stale, and I’ve been greatly remiss about that this year. I’ve done a massive amount of cleanup in the last week or two, but I don’t think I had much to your posts before June 11.

I’m catching up though! Next is to update the main post with current knowledge.

And why do you keep posting Jennifer+Love+Hewitt+04.jpg?


If I want to test posting and image,
I will test an image worth posting.

By the way, my questions were rhetorical. I was testing formatting code on images, text, and videos all of which kept disappearing then reappearing so I just typed out what I was thinking at that time.

“… the gasoline you buy might trace its heritage to carbon dioxide pulled straight out of the sky… engineers … have demonstrated a scalable and cost-effective way to make deep cuts in the carbon footprint of transportation…”

1. So their machine can recognize the difference between a CO2 molecule produced by anything transportation related, and all other CO2 molecules?
2. By “cost-effective” I assume they mean they have a product that some willing buyer someplace is willing to pay them an amount that will be greater than the cost it takes them to produce, market and deliver that product? ‘Cuz iffen they don’t, it ain’t “cost-effective”.

“…claim that realizing direct air capture on an impactful scale will cost roughly $94-$232 per ton of carbon dioxide captured…”

3. So what’s that in $/gal of gasoline? (See 2. above WRT “cost-effective”.) Will it have the same BTU/gal as gasoline?
So, yeah, other than that, Mrs. Lincoln, how did you like the play?

[Hammer is thrown at the screen]

We shall prevail!


A little late on the discussion, but this is one of the worst articles written by Dr. Ball I have read in years.

First let us start with where I take a huge exception:

This fits the Mauna Loa trend very nicely, but the measurements and instrumentation used there are patented and controlled by the Keeling family, first the father and now the son.

While C.D. Keeling was the first to measure CO2 with an IR beam (NDIR), and smart enough to make himself an extremely accurate (gravimetric) device to calibrate any CO2 measuring device with extreme accurate calibration mixtures.
The Scripps institute where Keeling worked later provided all calibration mixtures for all devices worldwide. Since 1995, calibration and intercalibration of CO2 mixtures and measurements worldwide are done by the central lab of the WMO.
Ralph Keeling works at Scripps and has no infuence at all at the calibration work of the WMO, neither on the measurements at Mauna Loa, which are done by NOAA under Pieter Tans.

As Scripps lost its control position, they still take their own (flask) samples at Mauna Loa and still have their own calibration mixtures, independent of NOAA. Both Scripps and NOAA measurements are within +/- 0.2 ppmv for the same moment of sampling. If NOAA should manipulate the data, I am pretty sure Scripps/Keeling would get them…

Beyond that, there are about 70 “background” stations, managed by different organisations of different countries, measuring CO2 on as far as possible uncontaminated places, from the South Pole to near the North Pole (Barrow), which all show, besides seasonal changes, which are more explicit in the NH, the same trend: up at about half the rate of the yearly human injection and a lag of the SH, which points to the main source of the increase in the NH, where 90% of human emissions occurs.

Thus Dr. Ball, if you want to accuse somebody of manipulation, first have your facts right.

Where is the reflection of CO2 increase due to the dramatic ocean warming and temperature increase caused by El Nino?

There is, if you look at the yearly rate of increase at Mauna Loa:


The 1998 and 2015 El Niño’s give a clear increase in yearly CO2 increase in the atmosphere. The 1992 Pinatubo explosion shows a huge dip in CO2 increase.

The reason, in part the ocean temperature in the tropics, but the dominant factor is (tropical) vegetation due to (too) high temperatures and drying out of the Amazon as the rain patterns change with an El Niño and increased photosynthesis after the Pinatubo injection of light scattering aerosols into the stratosphere:


It is pretty clear that changes in temperature rate of change lead changes in CO2 rate of change with about 6 months. The interesting point is that the δ13C (that is the ratio between 13CO2 and 12CO2) rate of change changes in opposite direction. That is the case if the increase/decrease in CO2 rate of change is caused by decaying/growing vegetation. If the CO2 rate of change was caused by warming/cooling oceans, then the CO2 and δ13C rate of change changes would parallel each other.

Again Dr. Ball, a little more research would have shown that you were wrong in your accusation.

It is getting late here, more comment tomorrow…
