Open Thread – trying out a new comment system

Hello,

Now that the move has been successful, I’m trying out a new commenting system plugin called WPDISCUZ.

You can read more about it here. https://wpdiscuz.com/

The original comment editor I installed last week didn’t work properly for everyone, and it screwed up comment indentation, so I had to disable it.

Try it out, leave a comment, leave a comment rating, try the sort features, etc. You can edit a comment up to 15 minutes after making it.

You can also visit another thread to see how it looks with many comments already in place.

-Anthony

 

UPDATE: I think I have the “reply” in nested comments working, and the EDIT function working properly. Also, the good news is that once you put in your name and email, it should always remember you….at least that is what I’m told by the documentation.

The bad news: General comment form is at the top, and there appears to be no way to change it according to this thread:

https://gvectors.com/forum/how-to-and-troubleshooting/remove-the-comment-form-to-below-comments/#post-3911

So, just use it for a general comment about the article, or scroll down and reply to an existing comment.

 

UPDATE2: You can display an image (or YouTube video) within a comment, (see examples in the thread below) but you MUST use https rather than http. Just simply insert the image URL, no tags or HTML needed.

If you use http all you’ll get is a link, but no embedded image.

Feel free to play around with inserting images or video in comments below.

Climate Change Has Run Its Course

Climate change is over. No, I’m not saying the climate will not change in the future, or that human influence on the climate is negligible. I mean simply that climate change is no longer a pre-eminent policy issue. All that remains is boilerplate rhetoric from the political class, frivolous nuisance lawsuits, and bureaucratic mandates on behalf of special-interest renewable-energy rent seekers.

Judged by deeds rather than words, most national governments are backing away from forced-marched decarbonization. You can date the arc of climate change as a policy priority from 1988, when highly publicized congressional hearings first elevated the issue, to 2018. President Trump’s ostentatious withdrawal from the Paris Agreement merely ratified a trend long becoming evident.

A good indicator of why climate change as an issue is over can be found early in the text of the Paris Agreement. The “nonbinding” pact declares that climate action must include concern for “gender equality, empowerment of women, and intergenerational equity” as well as “the importance for some of the concept of ‘climate justice.’ ” Another is Sarah Myhre’s address at the most recent meeting of the American Geophysical Union, in which she proclaimed that climate change cannot fully be addressed without also grappling with the misogyny and social injustice that have perpetuated the problem for decades.

The descent of climate change into the abyss of social-justice identity politics represents the last gasp of a cause that has lost its vitality. Climate alarm is like a car alarm—a blaring noise people are tuning out.

This outcome was predictable. Political scientist Anthony Downs described the downward trajectory of many political movements in an article for the Public Interest, “Up and Down With Ecology: The ‘Issue-Attention Cycle,’ ” published in 1972, long before the climate-change campaign began. Observing the movements that had arisen to address issues like crime, poverty and even the U.S.-Soviet space race, Mr. Downs discerned a five-stage cycle through which political issues pass regularly.

The first stage involves groups of experts and activists calling attention to a public problem, which leads quickly to the second stage, wherein the alarmed media and political class discover the issue. The second stage typically includes a large amount of euphoric enthusiasm—you might call it the “dopamine” stage—as activists conceive the issue in terms of global peril and salvation. This tendency explains the fanaticism with which divinity-school dropouts Al Gore and Jerry Brown have warned of climate change.

Then comes the third stage: the hinge. As Mr. Downs explains, there soon comes “a gradually spreading realization that the cost of ‘solving’ the problem is very high indeed.” That’s where we’ve been since the United Nations’ traveling climate circus committed itself to the fanatical mission of massive near-term reductions in fossil fuel consumption, codified in unrealistic proposals like the Kyoto Protocol. This third stage, Mr. Downs continues, “becomes almost imperceptibly transformed into the fourth stage: a gradual decline in the intensity of public interest in the problem.”

PRESENTATION OF EVIDENCE SUGGESTING TEMPERATURE DRIVES ATMOSPHERIC CO2 MORE THAN CO2 DRIVES TEMPERATURE
By Allan M.R. MacRae, P.Eng., June 13, 2015
https://wattsupwiththat.com/2015/06/13/presentation-of-evidence-suggesting-temperature-drives-atmospheric-co2-more-than-co2-drives-temperature/

Observations and Conclusions:

1. Temperature, among other factors, drives atmospheric CO2 much more than CO2 drives temperature. The rate of change dCO2/dt is closely correlated with temperature and thus atmospheric CO2 LAGS temperature by ~9 months in the modern data record. The rate of change dCO2/dt vs. temperature plot follows:

https://www.woodfortrees.org/plot/esrl-co2/from:1979/mean:12/derivative/plot/uah5/from:1979/scale:0.22/offset:0.14

2. CO2 also lags temperature by ~~800 years in the ice core record, on a longer time scale.

3. Atmospheric CO2 lags temperature at all measured time scales.

4. CO2 is the feedstock for carbon-based life on Earth, and Earth’s atmosphere and oceans are clearly CO2-deficient. CO2 abatement and sequestration schemes are nonsense.

5. Based on the evidence, Earth’s climate is insensitive to increased atmospheric CO2 – there is no global warming crisis.

6. Recent global warming was natural and irregularly cyclical – the next climate phase following the ~20 year pause will probably be global cooling, starting by ~2020 or sooner.

7. Adaptation is clearly the best approach to deal with the moderate global warming and cooling experienced in recent centuries.

8. Cool and cold weather kills many more people than warm or hot weather, even in warm climates. There are about 100,000 Excess Winter Deaths every year in the USA and about 10,000 in Canada.

9. Green energy schemes have needlessly driven up energy costs, reduced electrical grid reliability and contributed to increased winter mortality, which especially targets the elderly and the poor.

10. Cheap, abundant, reliable energy is the lifeblood of modern society. When politicians fool with energy systems, real people suffer and die. That is the tragic legacy of false global warming alarmism.

“COLD WEATHER KILLS 20 TIMES AS MANY PEOPLE AS HOT WEATHER“
By Joseph D’Aleo and Allan MacRae, September 4, 2015

________________________________________________________________________

ADDENDA:

A. RE POINT #1 ABOVE: THE RELATIONSHIP BETWEEN THE ~9-MONTH CO2 LAG AND THE AVERAGE ~36-MONTH TEMPERATURE CYCLE IN THE EQUATORIAL PACIFIC.

Introduction:

I proved in January 2008 that the rate-of-change dCO2/dt varies ~contemporaneously with global atmospheric temperature, and its integral the atmospheric CO2 trend lags temperature by ~9 months.
http://icecap.us/images/uploads/CO2vsTMacRae.pdf
– See Figures 1 and 3

The integral of a sine curve lags the sine curve by 90 degrees, which equals 1/4 of the 360 degree full cycle.

CO2 lags temperature by about 9 months, therefore this total cycle time should be about 4×9 = 36 months.

Hypothesis:
This approx. 36 month cycle is the Equatorial Pacific Sea Surface Temperature (SST) Cycle and the Global Temperature cycle.

Equatorial Pacific Ocean SST’s and global atmospheric temperatures have a natural temperature cycle (peak-to-peak) averaging about 36 months peak-to-peak.
For example, based on UAH LT temperature peaks, the mean cycle is 36.3 months and the lag is 9.1 months vs the approx. 9 months in my 2008 icecap.us paper.

The above Hypothesis is supported by the evidence.

B. GLOBAL ATMOSPHERIC TEMPERATURES CLOSELY FOLLOW EQUATORIAL PACIFIC OCEAN TEMPERATURES WITH A 4-to-6 MONTH LAG

https://wattsupwiththat.com/2018/04/28/solar-activity-flatlines-weakest-solar-cycle-in-200-years/comment-page-1/#comment-2803244

Summary:

The Equatorial Pacific Ocean has a natural Sea Surface Temperature cycle averaging about 36 months peak-to-peak.

Equatorial average air temperature and humidity follow Equatorial Pacific Ocean temperature – about 3 months after the Nino34 SST Anomaly and about 5 months after the East Equatorial Upper Ocean Temperature Anomaly.

Global average air temperature follows Equatorial average air temperature and humidity about 1 month later – about 4 months after the Nino34 SST Anomaly and about 6 months after the East Equatorial Upper Ocean Temperature Anomaly.

Notes:
“Sato” is an adjustment for the Sato Global Mean Optical Depth Index – the volcanic atmospheric aerosol index.
Formula: UAHLTcalc Global (Anom. in degC) = 0.20*Nino3.4IndexAnom (four months earlier) + 0.15 – 8*SatoGlobalMeanOpticalDepthIndex
Data: Sato Global Mean Aerosol Optical Depth at 550 nm https://data.giss.nasa.gov/modelforce/strataer/tau.line_2012.12.txt

C: ALSO RE POINT #1 ABOVE: HUMLUM ET AL REACHED SIMILAR CONCLUSIONS IN 2013:
https://www.sciencedirect.com/science/article/pii/S0921818112001658

“Highlights:
– Changes in global atmospheric CO2 are lagging 11–12 months behind changes in global sea surface temperature.
– Changes in global atmospheric CO2 are lagging 9.5–10 months behind changes in global air surface temperature.
– Changes in global atmospheric CO2 are lagging about 9 months behind changes in global lower troposphere temperature.
– Changes in ocean temperatures explain a substantial part of the observed changes in atmospheric CO2 since January 1980.
– Changes in atmospheric CO2 are not tracking changes in human emissions.”

D. CONCLUSIONS:

I suggest that the global warming alarmists could not be more wrong. These are the true facts, which are opposite to their alarmist claims:

1. CO2 is plant food, and greater atmospheric CO2 is good for natural plants and also for agriculture.

2. Earth’s atmosphere is clearly CO2-deficient and the current increase in CO2 (whatever the causes) is net strongly beneficial.

3. Increased atmospheric CO2 does not cause significant global warming – regrettable because the world is too cold and about to get colder.

Hi again Anthony and Moderators:

I changed all http to https and your new Comments system still deleted many urls, while displaying some of them.

Also, most of the url’s that did appear did not work but instead displayed error messages.

If it helps to diagnose problems, let me know and I will email you the full post – it is difficult to diagnose here because parts of it are just gone – url’s deleted – and most of the url’s that do appear no longer work – instead get error messages.

So my original comment stands – this post is trashed by your new Comments system – and probably also every other long post I have made on wattsup, where I often support my claims and/or shorten my posts with supporting url’s.

If I am doing something wrong then let me know – but I have to assume that all my previous long posts that include url’s have been similarly trashed.

Best personal regards, Allan

Hate it so far Anthony, but maybe I just don’t understand all the features.

How do you record a link in your own records to your post so you can refer to or find your post later?

So far this system has trashed my older posts, dropping urls irregularly, messing up line spacing, paragraphs, figures, etc.

It has features I will never use, and drops the ones I do use.

Apologies – this has put me in a really bad mood – I think I will now go and kick the cat.

How do you record a link in your own records to your post so you can refer to or find your post later?

There is an icon to the right of your name representing two links in a chain.
Click it, then try to navigate around the stupid social networking icons that pop up over the URL so that you get get a cursor on the URL,
then swipe the URL with your mouse, copy it,
paste it into your address bar and save it as favorite/bookmark.

.e.g: direct link to your comment:

Ghostery for either Chrome or Firefox is an add on. I am giving up on Firefox though, and sticking with Chrome. Gostery gives great control over trackers on all sites, except for here where it is best to disable it. It speeds up page loading quite a bit when it shows you which tracker is impeding the page the most. You then block that one and a page may go from 6 or 8 seconds down to 2 or 3 seconds on loading. Quite a nice difference, imo.

Two points,

a) I frequently receive duplicate emails to the same address (see below)
b) much prefer reading on the iPhone WordPress app but since the change, all I see is just the first paragraph of the post and nothing more. Will this be fixed?

Did you see the editorial in this week’s Oil & Gas Journal (4th June), I’d send you a link if I knew how. Very good article about the struggle between Alberta and BC over the way the central government have, essentially nationalised the Kinder Morgan Trans Mountain pipeline project after it was blocked by the activist (propped up by greens) government in BC? It’d be worth a comment on WUWT.

Testing a tweet link…

First, here’s what the link looks like (mobile version, with some zero-width spaces inserted so WordPress won’t recognize it as a URL):

https​:​/​/​mobile.​twitter.​com/DrAndreaDutton/status/1002949534597746690

This is the mobile version:

https://mobile.twitter.com/DrAndreaDutton/status/1002949534597746690

This is the non-mobile version (same URL as mobile version, but with the “mobile.” deleted):

https://twitter.com/DrAndreaDutton/status/1002949534597746690

Well, that’s not good. ☹️
 

Hmmm… it doesn’t update the URL in the address bar, either, though I guess the link symbol 🔗 feature is almost as good.
 

“ ” works properly to add an extra line of space—that’s a good thing—one of my favorite little formatting tricks, in fact.

June 4, 2018 10:33 pm

OK, I’ll use this opportunity to ask a question I always want to ask.
Am I wrong in the following statement about Einstein’s equivalence principle — and, if so, where I am wrong?

Rocket acceleration and gravitational acceleration are different things, there is no equivalence between them if the observer uses precision plumb lines and atomic clocks. If one installs three plumb lines on the ceiling of the windowless experimental chamber, and two atomic clocks, one on the ceiling and one on the floor of the same experimental chamber, under rocket acceleration of 1g plumb lines will be parallel, and atomic clocks will be synchronous. Under gravitational acceleration of 1g plumb lines will point at the center of the mass (not parallel), and the atomic clock on the ceiling will be ahead of the clock on the floor.

Where’s equivalence here?

P.S. Editing works!

Reply to  Alexander Feht
June 4, 2018 11:06 pm

The atomic clocks are each experiencing different accelerations because their distance r to the center of the Earth is different. The clock closer to the center has more acceleration due to gravity on it, and thus it runs slower.
If you saw the movie Interstellar, they use this trick where 3 astronauts go into deep gravity well planet for only a few hours by their clock, yet their companion who stays outside the well ages like 15 years.
Atomic clocks exeriencing the same force due to gravitational acceleration will not measure any time dilation due to differences in how fast they tick. And if that force is due to linear (or centripetal) acceleration, the clock will not show any delta t.

Centripetal acceleration also has GR effects known as frame dragging. Frame dragging has been observationally verified with satellites and I think in paired magnetars.
https://en.m.wikipedia.org/wiki/Frame-dragging

What you are describing is tidal force. WIth those two clocks spaced at different r from center of Earth, thus the force due to gravity is different, and solid objects get stretched (because they are extended bodies) by tidal forces and not mathematical points.

Black holes with sharp event horizons “spaghetti-fy’s” matter as it enters due to tidal stretching. Not pretty if you are an astronaut approaching the event horizon. An extremely massive black hole though the tidal forces may be so low that matter can survive event horizon passage. No one in this universe knows what comes next.

Reply to  Alexander Feht
June 4, 2018 11:33 pm

As far as the difference in line spacing between plumb lines at the top and at the bottom near the plumb, that has nothing to do with GR. One problem with your experimental setup is the top bar the strings are attached to is linear, not curved. So the center line is closer to the ground than the two outer lines, unless you curve the top bar to the produce the same r from the center of Earth. The lines still would not be parallel though. That is the geometry of the forces.

Importantly though the tension (force) on all three strings though is equivalent if the plumb bob masses are equivalent whether the acceleration is due to gravity or linear acceleration.

Reply to  Joel O’Bryan
June 5, 2018 1:08 am

Thank you very much for your explanation.
Since the pace of time indicated by atomic clocks depends on the distance from the center of mass, there is a difference in their readings. In the case of rocket acceleration there would be no such difference. Therefore, there is an experimental way to determine the nature of acceleration (gravitational vs. rocket-produced)? Even if there are no other means to observe or establish this result (in otherwise identical conditions)? Do I understand it correctly?

I thought you were already married to the lady with the gun.

I am certain that in the above comment eyesonu tab#1 was playing edit tricks on eyesonu tab#2 by changing the comment repeatedly. eyesonu tab#2 could not respond ’cause the comment kept changing every time he ‘refreshed’. eyesonu tab#2 was not going to play eyesonu tab1’s game.

Just think …. flexible, movable goal posts and everyone gets to move them. Let’s have a new game called “Goal posts you can’t believe in because everyone is moving them”. Give me an Ouija board for confidence.

Ugh!

I tried to post a long comment, a reply to my own comment. It didn’t seem to work. It did the “Knight Rider back-and-forth wait thing” and then… nothing. I was still looking at the bottom half of my long comment.

Tried a few more times, with the same result.

Eventually I scrolled up in just time to see a very brief error message at the top of my comment, which was just disappearing as I glimpsed it:

    We are sorry, but this comment cannot be posted. Please try later.

This commenting system is pretty bad, from a usability point of view. Look at all the problems with that behavior:

1. The error message is far from where your eyes are focused: the “Post comment” button is at the bottom of the comment, but the error message is at the top — which is hidden off the screen under some circumstances.

2. The error message goes away almost before you have time to read it. In fact, it took about 3 or 4 tries to selected it and copy to clipboard fast enough to catch it.

3. An error message which doesn’t say what is wrong, nor what to do about it. (Well, it says what to do about it (“try later”), but that advice is wrong.)

I spent the next twenty minutes of so trying to narrow down the cause of the problem.

The actual problem turned out to be that my original comment was gone!

I guess that’s an artifact of the malfunctioning new anti-spam feature. So, more problems:

4. It flagged non-spam as spam. (But Akismet often did this, too.)

5. It hid the message, without telling the user. (Akismet did this, too, but at least with Akismet you could tell that it had happened.)

6. It wouldn’t let me post a repy to it, and didn’t say why not, and wasted a bunch of my time trying to figure it out.

It is also annoying that you see only a small snippet of a comment until clicking “Read more” — and the formatting is mangled in that small snippet.

And why is the text size so tiny in the replies?

I like the long edit time. I dislike the lack of a countdown timer. I typed an elaborate edit, but when I tried to post it I got an error:

    Sorry, this comment no longer possible to edit

So, the 15 minute timer runs silently, and it doesn’t reset when you post an edit. In other words, if you make an edit at 10 minutes, you only have 5 minutes left to make another edit. That’s not ideal for OCD guys who want to keep tweaking the comment and inspecting the result, to get it just right.
 

Here’s what I was trying to test (in my rejected “edit,” above). I was trying to make tweets non-invisible.

First, I showed what I was going to enter (with zero-width spaces added, and < as &lt;, to prevent WordPress’s magic, so you can read it):

<a href=”https​:/​/mobile.twitter.com/DrAndreaDutton/status/1002949534597746690″>http​s:/​/mobile.twitter.com/DrAndreaDutton/status/1002949534597746690</a>

And here it is without the obfuscation:

https://mobile.twitter.com/DrAndreaDutton/status/1002949534597746690

And her’s the non-mobile version:

https://twitter.com/DrAndreaDutton/status/1002949534597746690

And here’s the non-mobile version with zero-length spaces obfuscating only the inner URL:

https:​//twitter.com/DrAndreaDutton/status/1002949534597746690

And here’s a simpler attempt: the non-mobile version with the “https:​//” deleted from the inner URL ((instead of inserting zero-length spaces to obfuscate it):

https:​//twitter.com/DrAndreaDutton/status/1002949534597746690

Well, how about that?
