Media Can’t Agree on the Number of Climate Tipping Points, Much less When

From ClimateREALISM

Following the publication of story in The Guardian by Damian Carrington last week, titled, “World on brink of five ‘disastrous’ climate tipping points, study finds,” numerous corporate media outlets picked up the theme and ran their own stories. Based on a single study, titled “Exceeding 1.5°C global warming could trigger multiple climate tipping points,”  The Guardian and many other news outlets wrote stories treating the study’s speculative claims as proven, although they couldn’t agree on the number of tipping points: The Guardian said five, the BBC said six, and Grist says sevenCBS News, erring on the conservative side, says four.

Claims that the earth faces a climate tipping point beyond which disaster looms are not new, and the present claims are no more likely to be true or supported by evidence than previous such claims were. There is no data or measureable trend which provides scientifically sound evidence that the earth is hurtling towards an apocalyptic climate tipping point, or even that such tipping points exist.

Describing the study, Grist writes:

Giant ice sheets, ocean currents and permafrost regions may already have passed point of irreversible change

The climate crisis has driven the world to the brink of multiple “disastrous” tipping points, according to a major study.

It shows five dangerous tipping points may already have been passed due to the 1.1C of global heating caused by humanity to date.

These include the collapse of Greenland’s ice cap, eventually producing a huge sea level rise, the collapse of a key current in the north Atlantic, disrupting rain upon which billions of people depend for food, and an abrupt melting of carbon-rich permafrost.

At 1.5C of heating, the minimum rise now expected, four of the five tipping points move from being possible to likely, the analysis said. Also at 1.5C, an additional five tipping points become possible, including changes to vast northern forests and the loss of almost all mountain glaciers.

In case you are unfamiliar with what a climate tipping point is, the theory behind climate tipping points is described at Climate At A Glance: Tipping Point – 1.5 Degrees Celsius Warming

In point of fact, in the study cited by the media, the researchers used computer models to calculate 16 tipping points, with the final six requiring global temperature increase of at least 2°C to occur. According to the scientists’ computer model estimates, the tipping points would take effect on timescales varying from a few years to centuries.

Note the word “could” in the title of the original article, and the timeline uncertainty. In other words, the scientists made a guess. And, importantly, the guess is based on computer models that are known to be flawed, rather than real-world, measured, evidence.

We’ve been warned of climate tipping points before, so much so that they’ve racked up an impressive record of non-performance.

For example. Google search shows well over a hundred, here is just a few of them:

“In spite of the continued released [sic] of 90 million tons of global warming pollution every day into the atmosphere, as if it’s an open sewer, we are now seeing the approach of a global political tipping point.”–Al Gore, interview with Washington Post, Aug. 21, 2013

It seems there is always a climate tipping point in our future, and they never seem to happen. Every year we are treated to a fresh set of dire predictions, with the goal posts for when they will occur, always somewhere in the future, but never certain.

In June 2011, The University of East Anglia (UEA) saw tipping points behind every rock and tree, suggesting an “early warning system” be created. You can see the list of them in the figure below. Most of them are the same ones making the rounds in the media today and cited by the new study.

Figure 1. Presentation on a proposed “early warning system” for tipping points by UEA in 2011. Source:

But, in 2022, 11 years later, none of those catastrophes has occurred, despite no “early warning system” ever being created. Perhaps the reason is that other peer-reviewed science shows tipping points have not happened in Earth’s distant past in response to atmospheric carbon dioxide changes.

A signifcant paleoclimate study from the University of Washington says tipping points aren’t likely to ever happen from increased carbon dioxide in our atmosphere.

The press release for the study, titled “Atmospheric carbon dioxide buildup unlikely to spark abrupt climate change” says this:

There have been instances in Earth history when average temperatures have changed rapidly, as much as 10 degrees Celsius (18 degrees Fahrenheit) over a few decades, and some have speculated the same could happen again as the atmosphere becomes overloaded with carbon dioxide.

New research lends support to evidence from numerous recent studies that suggest abrupt climate change appears to be the result of alterations in ocean circulation uniquely associated with ice ages.

But even more importantly, the new study pushed by the the media in the past week based the claims of future disaster on a temperature rise of 1.5°C – the problem is, they don’t seem to realize that this has already occurred.

Below in Figure 2 is the Berkeley Earth average surface temperature record for Europe since about 1780. Europe is a good location to analyze, because some of the longest continuous temperature records are from Europe. It shows that not just 1.5°C, but 2.0°C of warming has already occurred.

Figure 2. (click to enlarge) Berkeley Earth average European temperature showing a 2.0°C rise since about 1820. Source: Annotated by Anthony Watts

Yet even with 2 degrees celsius of atmospheric warming since about 1820, the claimed catastrophic climate tipping points have not occurred.

Despite evidence to the contrary provided by real-world-data, climate alarmism over future tipping points seems to be a constant feature of the media, but they never happen – “its déjà vu all over again.”

Asserted disastrous “tipping points” may make for good headlines and story ledes, but there is no evidence any exist. Also, with the tremendous adaptability humans have shown to changing climate conditions across the course of time and widely varying environments, and the consistent progress society has displayed accompanied by revolutionary technological innovations, there is no reason for believing that humans face any catastrophic tipping points now.

From your link.

Fossil fuel extractors will be asked by the EU to give back 33% of taxable surplus profits for the 2022 fiscal year, in a move that could pile pressure on Liz Truss to reverse her decision not to extend the UK’s windfall tax on oil and gas companies, which is set at 25%. Truss has ruled out extending the £5bn windfall tax on energy companies introduced by the former chancellor Rishi Sunak.

This reported study appears to run counter to current orthodoxy regarding the current 0.8C of temp rise (modern thermometer measurements (ALA Mike’s Nature Trick)) over 5 decades being unprecedented. How could 0.8c over 50 years be unprecedented if studies indicate 10c over a few decades?

We don’t know what caused the previous warming episodes.
However we know for a fact that whatever did cause them isn’t causing the modern warming because the climate models have proven that CO2 is causing it.

I only wish the above was sarcasm. I’ve been told exactly that by several alarmists.

Something else I’ll be puzzling over for a while. Why are Boreal Forests doomed when the link is all about fires. After a fire has passed through the forest returns and won’t be bothered by fires again for 2 or 3 decades.

I’ve still not got a logical reason for retreating glaciers being a problem. Advancing glaciers, assuming no real change in precipitation, means a percentage of water retained annually. While the glacier is melting there will be increased river flows. Once gone the the precipitation will go into rivers that year, delayed by several months as in winter a lot will still be in the solid form of H2O.

Well it keeps the brain active

How many tipping points?

How about 2000 thunderstorms at any given time? About 16,000,000 per year. Every one of them occurred as a result of an unstable atmosphere passing a “tipping point.” So there’s that.

The climate system self-compensates so effectively because its powerful operation will not support the accumulation of heat energy at the surface to harmful effect on the planet from what non-condensing GHGs do.

September 14, 2022 6:41 am

My problem with tipping points is that they are not specific to greenhouse warming or CO2. Any perturbation in the long-term earth surface temperature would trigger them, so we’d already have tipped long ago, and now be living on a Helliconia earth.

CO2 has never been empirically demonstrated to drive the Earth’s temperature at all, so the notion that any “tipping point” will be caused by something demonstrably incapable of inducing a temperature effect to begin with is ludicrous on its face.

And previous warmer-than-today warm climate periods weren’t called “Climate OPTIMUMS” because there was anything “bad” about them. Quite the reverse – warm climate is the BEST climate. One the biggest lies they’re selling is the ridiculous notion that ‘warmer climate = worse weather’ – that’s not just wrong, it’s 180 degrees wrong.

This is truly sad. The younger generations have been taught to feel guilty, and to worry, about many un-true things. The man-made global warming, but in general any ecology things such as litter and wasting water. Also, the ethics of eating other animals.

My daughter, and another family member, went vegetarian for a while as young adults. They coincidentally had a range of health problems. They each, independently, decided to transition back to eating meat, and the health problems cleared up.

When passing through, I think it was, third grade, each of my sons learned about wasting water, and came home encouraging us to not waste water. Such as: turn off tap while brushing your teeth.

I asked them:
where does the water come from? From the water treatment plant. Where does that come from? From the Lake [we have surface water supply.]
Where does it go when I run the tap? To the water treatment plant.
Then where? To the creek.
Then where? To the ocean.
Then where? Evaporates to clouds.
Then where? Clouds drift over to land, and rain.
Where does rain go? To the Lake.

So, where did we waste the water?

They are simultaneously being taught the water cycle, and that water is being “wasted.”

The only water wasted, in the sense of the water cycle, is in drought. Don’t use it up frivolously. We have had drought, and the Lake got really low. Some summers are drier than others. We have had other seasons of flooding, and the water utility wishes all of us could run taps all day to drop the Lake level so it does not breach the dam and cause uncontrolled damage!

The other waste of water is when it becomes intoxified with chemicals or Nukular energy. We have to watch those.

“We” have water desalination technology, and other technology. When water scarcity becomes enough of a problem in the Levant, or California, “we” will invest in desalination plants hearty enough to support everyone.

In the meantime, I watered my lawn in this summer’s drought and had my water bill go from $70 to $120. If water is so rare, how can it be so affordable to broadcast it willy nilly all over the yard?

“There have been instances in Earth history when average temperatures have changed rapidly, as much as 10 degrees Celsius (18 degrees Fahrenheit) over a few decades”

Yes, there is evidence for two regimes in climate, delightfully warm and frigging cold. There is no paleo evidence for rapid and significant change from warm state to a much warmer state. A minor increase in a trace atmospheric gas cannot flip the climate to a hot house earth.

What I always find strange about such lists is that when I look at actual data, I just can not see any reason for concern.

The things that concern me about the climate/weather are never listed or discussed.

The earth is overdue for a smack from a CME. The data is clear. They happen regularly (every 150 years.) Is the world ready for another Carrington Event? What about a much strong solar event?

The weakening of the Earth’s magnetic field gets little attention. I just don’t understand why. Watching the drift of the poles towards each other is fascinating. While I’m not exactly sure how fast it’s weakening, it started in the 1800s, if not earlier. Is it now weakening at 5% per decade? If it continues, the effect on weather/climate could be significant.

Any guesses (other than I am just stupid) as to why these obvious risks get little attention?

Ahhhh, I see your problem.

Silly! The tipping point problem of today is different from the tipping point of 1750. That was obviously a 0.8C higher tipping point back then because we measure 1.5C from 1850, not from 1750 when the Earth was colder and had yet to go back to the normal temperature it had been for over 2,000 years, except for the odd Medieval Warm Period and Little Ice Age. And because of the Little Ice Age that came after the Medieval Warm Period, all the melted ice from the MWP was there as water to freeze back into ice during the LIA, making SO much more ice by 1850 when fossil fuels started the postMWP extra ice melting again, today physics and people are different. Because climate change changes everything including scary movies about Climate Change, which you should see because Climate Change is really scary!

I hope this clears things up.

I’d love to see the actual math on how mankinds affect on less than .1% (CO2 and CH4) of the atmosphere is 100% responsible for anything but hyperbole.

That’s ‘hyperbowl’ according to our illustrious female ex PM but are you sitting down relaxed and comfortable? Because after years of painful onerous study I have finally discovered a report of a natural event that has not been blamed on CO2 dooming and hereby publish that result for peer reviewing-

Also, with the tremendous adaptability humans have shown to changing climate conditions over time and widely varying environments and the consistent progress society has displayed accompanied by revolutionary technological innovations, there is no reason for believing that humans face any catastrophic tipping points now.”

Yes, humans are a species with great skill at adapting. That said, at no time prior to now that I know of, have humans had world leaders and power brokers so very determined to eliminate all the human mechanisms of adapting to climate change i.e. A/C, heating, transportation et al, all powered by fossil fuels.
Unfortunately, everything possible is being done to prevent human adaptations not only to climate change but to living comfortably with our current climate.
It is incomprehensible but it is what it is, astonishing and evil as it may be. Mankind has always been evil. I guess climate change policies are just the latest iteration of that evil.

There are no ketchup-effects in the climate system. The heat flow is wide open.

As if true positive feedbacks can exist everywhere in nature.

The never-ending atmospheric evolution that causes weather and climate are mathematically chaotic. Mathematical chaos theory, I believe, uses the term “phase changes” to describe the popular term “tipping points” in a chaotic system. It makes two predictions about such tipping points: 1) their TIMING cannot be predicted and 2) their SIGN cannot be predicted.

Thus, any actual scientist who talks seriously about tipping points is either an ignorant scientist or being deliberately deceptive. Most climate reporters are likely just the former of those two possibilities and can, perhaps, be forgiven. Scientists… not so much IMO.

What differentiates a “study” from a “major study”? Boy howdy, the latter sure sounds serious!

I must be missing something here, but if a number of these tipping points have already passed, why according to the UN’s own statistics has the world’s population, along with life expectancies and agricultural output, continued to grow, while poverty levels decrease? Maybe the planet and its inhabitants are a lot more resilient than the climate alarmists care to concede.
