20 Years of WUWT: What We’re Up Against & Why It Matters – Keynote Address at #ICCC16

For this special release, the video begins with an introduction from WUWT author and my good friend, Willis Eschenbach, whose insight and persistence have been part of the backbone of this site for many years.

What follows is my keynote address from ICCC16, marking twenty years of Watts Up With That.

Twenty years. That’s a long time to keep asking inconvenient questions.

When I started WUWT in 2006, it was a simple exercise in curiosity, looking at weather data, instrumentation, and the reliability of the systems we’re told to trust. It quickly became something more. A global platform where scientists, engineers, statisticians, and citizen researchers could examine climate claims with rigor, transparency, and a willingness to challenge assumptions.

In this talk, I walk through some of the milestones many of you helped make possible.

The Surface Stations Project; over 1,200 stations surveyed by volunteers, demonstrated that a large percentage of official temperature monitoring sites were compromised by poor siting. That wasn’t speculation; it was documented, photographed, and ultimately acknowledged.

Climategate: when thousands of internal emails revealed how data handling and peer review could be influenced behind the scenes, was another moment where WUWT stepped in early, providing analysis when much of the mainstream media hesitated.

Over time, WUWT grew into the most-viewed climate website in the world, with hundreds of millions of page views and contributions from respected scientists and independent thinkers alike.

But that’s only half the story.

Because asking questions—real questions about data quality, methodology, and conclusions—comes with a cost.

As I discuss in the keynote, the response hasn’t been limited to scientific rebuttal. Instead, we’ve seen systematic efforts to reduce visibility and limit reach. Google search delisting made it harder for new readers to find us. Advertising restrictions cut off a major source of revenue.

On a more personal level, there have been coordinated attacks; being doxed by a partisan website, facing threats, dealing with libel, and watching years of work dismissed without serious engagement.

That’s the environment independent climate analysis operates in today.

And yet, WUWT is still here.

No missed days. No editorial board filtering of what can or cannot be said. No corporate funding shaping the narrative. Just a commitment to follow the data wherever it leads—and to publish it openly.

Which brings me to the reason for this post.

WUWT has always been reader-supported. Despite years of accusations, there’s never been oil company funding. The site exists because readers decided it was worth keeping alive.

Today, that support matters more than ever.

If you value independent analysis…
If you think open debate in science still has a place…
If you believe data should be examined, not just accepted…

Then I’m asking you to help keep WUWT going.

My first published anti-CO2/global warming editorial letter was in the Colorado Springs Gazette in 1989, 37 years.
Now, if I only had a PhD w terabytes of esoteric publications I, too, could know everything about everything and never be wrong.

I would most appreciative if you could send a copy of your l etter via email to: harold.d.pierce@proton.me. I live in B.C. Canada where the industrial carbon tax is now $110 per tonne of CO2 equivilent and will rise to $130 by 2030. The consumer carbon tax of $80 per tonne of CO2 has just been terminated. B.C. was the first political jurisdiction in NA to impose a carbon tax on fossil fuels in 2009. The tax was $10 per tonne of CO2 equivilent.

The success of WUWT achieved by highly competent management has secured it an important place in the global history of computing. WUWT is a rare model of how early public computing developed into the blog that soon became a major path for those highlighting scientific findings, short of the formality of a peer reviewed published paper.
You all deserve to be proud of you place in history. Geoff S

Well done Anthony for 20 years service to science communication.

This blog is at the forefront of scientific communication on climate and energy. It is an active journal with audience participation.

I remember finding your site in 2006. You and Steve McIntyre were my introduction to the climate issue. I was impressed by your very grounded approach to errors in the temperature record because of Stevenson Screen issues. The last 20 years have been an adventure – I have appreciated the diligence with which you have kept us informed on Climate issues.
I would wish you another 20 years – but I hope the climate nonsense is resolved faster than that!

Same experience.
If WUWT exists in its current form in 2046, that would probably be bad – in the way that it would be bad if Americans today gathered round a dishwasher-sized radio in their living room to catch the latest episode of a serial drama about The Shadow or The Lone Ranger. They might instead be correcting each others’ grammar by wireless brain wave-interpreting headbands from their self driving fusion rocket cars by then.
Rather than editing an eponymous website in 2046, I hope Watts is enjoying some form of rum-and-coconut drink on the porch of a mountainside Hawaiian retirement cottage, laughing through his brainwave headband.

I have visited this site for almost as long as it has been in existence. It has been a great source of information and I thought, recently, it was about time I subscribed. I have never believed this global cooling/warming, climate catastrophe stuff as I have yet to see any evidence that supports it.
Thank you Anthony!

Congratulations Anthony.
It was around 2008 and thanks to the Daily Telegraph’s (late, great) Christopher Booker & James Delingpole promoting your site, many of your UK followers would never have known WUWT existed. I don’t post so much now, but do enjoy my daily WUWT fix! Thank you.

Same here, GeeJam. I had been concerned about dodgy ‘environmental’ science for a while, but it was a relief to find others thinking the same way. Thank you to Anthony and all at WUWT, and thank you to (the late great) Christopher Booker and James Delingpole for pointing me in this direction. Further back, thank you to Matt Ridley, for his contributions to the Economist, when it was a newspaper worth reading on these subjects. And thanks to Aaron Wildawsky, who confirmed my sense that we should keep asking ‘but is it true?’, however apparently ‘virtuous’ the cause.

I must have been one of the earliest contributors and have enjoyed it throughout.
The feedback helped me to arrive at what I now believe is a definitive answer on the issue in that the enhanced surface temperature of a planetary surface beneath an atmosphere is a by product of convective overturning of atmospheric mass and therefore nothing to do with atmospheric composition. Variations in composition are neutralised by changes in the rate and distribution of overturning.
That is still not generally accepted even though it is implied within the science that was accepted prior to the warming scare.
Science generally has been hugely damaged by the CO2 farrago.

Agreed, and this is confirmed by a physicist who discovered, by comparing Venus and Earth temperatures at the same atmospheric density, that the only differentiating factor necessary to explain the temperature difference…

is the distance from the Sun.

Mark Twain observed, “The trouble with most of us is that we know too much that ain’t so.”

Adding to the “Δ33C without an atmosphere” (see other article) that completely ain’t so is the example of Venus.

Venus, we are told, has an atmosphere that is almost pure carbon dioxide and an extremely high surface temperature, 750 K, and this is allegedly due to the radiative greenhouse effect, RGHE. But the only apparent defense is, “Well, WHAT else could it BE?!” (besides/also molten core volcanism)

Well, what follows is the else it could be: (Q = U * A * ΔT) aka a contiguous participating media.

Venus is 70% of the Earth’s distance to the sun, its average solar constant/irradiance is about twice as intense as that of earth, 2,602 W/m^2 as opposed to 1,361 W/m^2.
But the albedo of Venus is 0.77 compared to 0.31 for the Earth – or – Venus 601.5 W/m^2 net ASR (absorbed solar radiation) compared to Earth 943.9 W/m^2 net ASR.
The Venusian atmosphere is 250 km thick as opposed to Earth’s at 100 km. Picture how hot you would get stacking 1.5 more blankets on your bed. RGHE’s got jack to do with it, it’s all Q = U * A * ΔT.

The thermal conductivity of carbon dioxide is about half that of air, 0.0146 W/m-K as opposed to 0.0240 W/m-K so it takes twice the ΔT/m to move the same kJ from surface to ToA.

Put the higher irradiance & albedo (lower Q = lower ΔT), thickness (greater thickness increases ΔT) and conductivity (lower conductivity raises ΔT) all together: 601.5/943.9 * 250/100 * 0.0240/0.0146 = 2.61.

So, Q = U * A * ΔT suggests that the Venusian ΔT would be 2.61 times greater than that of Earth. If the surface of the Earth is 15C/288K and ToA is effectively 0K then Earth ΔT = 288C. Venus ΔT would be 2.61 * 288 C = 748.8 K surface temperature.

All explained, no need for any S-B BB LWIR RGHE hocus pocus.
Simplest explanation for the observation.

Well, you’re most definitely up against mad Ed Miliband, who doubtless considers the estimable Mr Watts to be nothing short of a climate vandal. And a persistent one at that. Funnily enough, throughout the current ‘cost of living/energy’ crisis Miliband has vanished into thin air and has not been seen since the news broke that he directed Starmer to block Trump’s use of British bases.

We have a rather unique problem, a PM who has lied time and again and now all the party leaders are calling for his resignation, but he will not go. Mad Ed hasn’t said he can.

We have a new joke; Nothing ever goes across Starmer’s desk, so why not put his desk in the English channel?

Anthony, thanks for the 20 years and keep up the good work. My first letter to the Editor, Reno Gazette Journal, about globull warming and the Geologic Record, was in 2002. This resulted in a phone call inviting me to come outside, where a man and his son were waiting, and to get tuned up by them for advocating pollution. I stuck 14 good friends of mine into the belt in my back and went outside, where a man shouted something and took off.

I hate to think what your experiences have been, but please hang in there.

Anthony is a meteorologist, which if I’m not mistaken, is considered a science.

While specific, early, or inaugural comments from Steve Case on Watts Up With That?

He remains a regular contributor to the site, offering critiques of climate models and data analysis through at least 2026. For more on his contributions, visit Watts Up With That?.
