A simple warning note to some WUWT commenters

As of late, we’ve had a few commenters that have engaged in “graph wars” i.e., they throw up an image of a graph with little more than “look at this” attached to it in a comment thread. Then someone else responds in the same way.

One of the most repeated graphs in the last two days is this one, being used multiple times:

USA-maxtemps
USA-maxtemps

There are others.

These are repeatedly uploaded into comments, each time somebody wants to make the same point they’ve already made elsewhere.

The problem:

  • Repetitive images used in comments get uploaded into our database each time they are used in a comment.
  • Each image takes significant space in the database, compared to a comment, and our database of WUWT content is already overloaded.
  • An overloaded database runs slower for everyone, and costs us more in the long run.
  • Many of the people doing this are not paid subscribers, so this ends up being a loss.

Then there’s the irritation of seeing these again and again and again. It adds nothing to the discourse.

So, here’s the deal. STOP IT.

You can link to external images rather than filling up our database.

If the problem worsens, I will be forced to limit image uploads to paid subscribers.

WUWT is in good company. Despite the scientific pivot, over 105,000 papers in Google Scholar mention RCP8.5, and thousands of papers utilizing the framework continue to be published.

Well, having never learned to post an image, I’m way ahead on this one.

Some people get a little attach image icon in the lower right corner of the edit box, others don’t (like moi).

Same, Paul. I have no idea what the criteria is that allows someone to post images vs. not.

Same. Having some knowledge of WordPress, I suspect that lack of an upload icon is due a permissions/roles issue. I’m guessing, but WUWT probably has several roles, for nonsubscribers, and varying levels of paid subscribers. I’d guess that the one we belong to is missing a permission.

Neither do I. Still don’t know how to upload images.

I always post links.
Sometimes it shows as a link. Sometimes it shows as an image.
I haven’t been able to figure out why.

Some links to images don’t point directly to the image. If it doesn’t end in .jpg, .png, or other accepted image, the system won’t interpret it as an image.

Is that a WordPress thing? My browser doesn’t seem to have any problem interpreting it as an image?

Just post a URL link to the graph if it exists somewhere else on the Internet and not just on your own PC. Readers of your comment may not click on it (especially if they don’t agree with you), but at least you referenced the source to support what you are saying.

I too am not sure how to post graphs in comments, so Anthony can be sure it won’t happen with me.

One can also post a link to a previous comment that has the image.

Anthony, have you considered imgur.com as imagehost? Typically used at phpBB discussion forums.

Correct attitude with some style…glad you’re keeping the lanes open for the rest of us!

July 7, 2026 1:15 pm

I apologise. Now that I know there is an issue, I will try to use links back to previous graphs.

Well, if you just post a link to a picture elsewhere it seems to work fine – and it will not occupy any local space. This here btw. a nice summary on why “climate science” WV was a pos. feedback, while it is definitely a large neg. feedback – in every single view.

The main process by far for warming of the air is: (1) sunlight warms the earth’s surfaces, (2) air contacts warm surfaces and by conduction heats up and (3) warm air rises up and by convection heats up the atmosphere. Advection is another process for warming of air in a region. For example, hot air from desert is blown by the wind to a nearby region. Hot air coming out of desert is called a siroccos. A light warm breeze from a desert is called a zephyr.

The greenhouse effect is not the main process for warming of air. In winter H2O and CO2 hibernate.

These articles are not for children.
The solar radiation is very broad band, not just “light”
The radiation is absorbed by all of planet earth – the entire atmosphere down to the surface, all the oceans and water bodies as well as the continents and islands.
So the “temperature” of each of these components of the planet depends upon the nature of the component and there are large differences amongst them and the idea of a mean or an average temperature is simply nonsense.
The entire “climate science” challenge is to eventually discover how to measure the energy which is totally coming into the planet and totally leaving the planet.
The warming claim is that overall less energy is shed than is received.
The devil is in the detail and the task is very difficult to accomplish.
Now, from where on earth did you get the utterly ridiculous assertion that an intrinsic property particular compounds can hibernate ?!?!

What about videos for which we post the link in a comment, and which redirects to YouTube? Maybe a silly question, but I know absolutely nothing about servers and hosting.

Reply to  Charles Armand
July 7, 2026 2:46 pm

If you are posting a link its basically a redirect to the actual content. All that should wind up in the database is the link itself, not the content. I say “should” because WordPress is a very convoluted environment that can have unexpected consequences to what looks like a simple code change.

I run several WP sites. Unless there is some weird plugin, no, links do not store the content in the WP database or on the server.

I upload my own graphics to a flickr account and hyperlink to them in my comments. WordPress then does the work of presenting them.

I keep a list of the individual flickr hyperlinks with descriptions of their contents so that when I want to reuse one, it’s right there.

I usually compose my comments in a text file, save it into a folder on my PC, and then load it into the WUWT comment box.

When it’s posted, I will then add the WordPress hyperlink for that particular comment into the text file.

I’ve got a text copy of nearly every comment I’ve made on WUWT going back twelve years or so.

July 7, 2026 2:29 pm

It seems there are two routes to slap an image up on WUWT.

(1) That little icon in the lower right on the posting dialog box is one that apparently loads into WUWT’s web page, delivers a reduced image at the bottom of your post that readers can click on that opens a new tab with the full size image displayed. I’m guessing that’s the one that chews up WUWT memory.

(2) Find or upload an image to an independent web page, copy the URL and paste it in your message. It will appear here at WUWT just fine.

I’m guessing I can continue to slap my favorite Eagle Eating Wind Mill up here at WUWT as often as I like if I use method (2)

If I’m wrong about all that please let me know.

Steve, hopefully this works. The link you created looks like this: 
“http://eagle%20eating%20wind%20mill/”
which will actually load in a browser as:
“http://eagle eating wind mill/” 
since the %20 represents a Space, which is invalid as it then contains spaces.
The best way to insert a link is to visit the page you wish to display and then Copy the url at the top and then Paste it into the link.

It might be good if the image file is as small as possible to save space.
I compared some different image formats:
a48ntv68.png: 1,095,538 bytes
gif: 251,756 bytes
jpg: 238,090 bytes

Better to just post the link, that’s usually 100 bytes or less.

The only problem is that some of the internet imagery that doesn’t support the MSM meme has a habit of disappearing. Thus, if one makes a claim and it is contested, it might be impossible to backup the claim. What might be helpful would be a list of WUWT images and a large ‘thumbnail’ so that if a commenter needs to remind someone of a point, they can provide a link to something that is already archived here.

July 7, 2026 2:41 pm

What are you storing the data on exactly?

Modern storage uses deduplication to solve this exact problem. The cheapest of the cheap storage arrays don’t have this feature but that’s a tiny sliver of the market. Message me directly if you want to explore this.

In some WP setups, users can access their own subset of the Media Library in WP. That means they can access items they’ve uploaded before and point them to the current comment. It’s understandable that WUWT doesn’t so this, as that can cause a bit of unnecessary overhead on the server.

But generally, you’re right.

Reply to  Jeff Alberts
July 7, 2026 9:06 pm

That’s the advantage of doing storage layer deduplication. It has no load on the servers, and its completely invisible to WP, users don’t need to have access to anything. Bonus, if someone quotes another comment in their own post, that gets deduplicated too. Someone could quote from a ten year old comment and it would get deduplicated.

Victor
July 7, 2026 2:47 pm

I usually use this method when the image is already uploaded, I right-click the image and select Copy image address or Copy image link. This copies the image’s direct URL to my clipboard.
Then I right-click in the comment and choose Paste. The link to the image is pasted into the comment.

Reply to  Victor
July 7, 2026 5:20 pm

Good tip! You are not uploading a new image, you are linking to an image that has already been previously uploaded to WUWT.

Now if I can just find my list of already-uploaded images. 🙂

When I read the heading: “A simple warning note to some WUWT commenters”, I assumed it would be about the frequent ad hominem attacks which many commenters on this site use in place of counter-arguments.

Anthony, does “upload into comments” only mean to use the little “Attach an image to this comment” button?
comment image

Or does it also mean images done the way I just did that one: by posting a link to a .png file hosted elsewhere?

As you know, I very often include multiple graphs and other images in my comments, by linking to .png, .jpg, and/or .gif files which reside on my sealevel.info website. Here’s an example from 20 days ago.

The images show up inline in my comments here on WUWT. Does that contribute to the problem, or is it okay?

I think the images are being loaded from my site, rather than your database, but can you please confirm that I’m not overburdening your server?
