As a car buyer, would you be willing to pay anything significant to get a vehicle with 0.011% better gas mileage? As a businessman, does a 0.011% change make a difference to your plans? Would you change your neighborhood of 20+ years for a 0.011% decrease in security risk, particularly if you knew it could reverse itself shortly thereafter?
Just to be sure we’re thinking realistically about the magnitude of 0.011%, we can also express it as only 110 in a million.
A technical paper recently published in Nature speaks breathlessly of massive volumes of ice melt in Antarctica—3 billion tons from 1992 to 2017!
But who can relate to a billion tons of ice? I confess I can’t even imagine what it would look like. If it were a cube, what would be its dimensions? If it were ten feet thick and five feet wide, how long would it stretch? How many glasses of tea would it chill? Do you have any idea, right off the top of your head? Neither do I.
And that’s what the authors of this and similar articles are depending on. They toss out astronomical numbers, confident that lay readers will have no sense of proportion for them.
However, when compared to the 27,000 billion tons of total Antarctic ice, we are worrying about a trivial 0.011% decrease over a 25-year period. That is, out of every million parts, Antarctica lost 110 in 25 years. At that rate, how long would it take to lose half of Antarctica’s ice? Over 100,000 years!
Suddenly the situation doesn’t sound quite so dire, does it?
In the real world where decisions of consequence are made, this is simply round-off—or “windage,” as a shooter pulling the trigger might say!
Yet, climate alarmists are spinning the 0.011% decrease in Antarctic ice mass over 1992–2017 as “we are in serious trouble” and “ice loss has tripled in a decade.”
Does this 0.011% decrease flood the world’s coastlines? Not unless your flood threshold is less than the width of your pinky (i.e., 0.31 inch).
As usual, alarmists project their supposed bad news forward into the future as invariably caused solely by the progress of civilization enjoying hydrocarbon fuels. If per chance this current rate of calculated rise in sea level were to continue (an assumption that has no justification other than hypothetical conjecture), then even over a period of 200 years we are looking at a sea level rise of less than 3 finger widths (i.e., 2.4 inches).
Should we panic and return to the horse and buggy to prevent it?
As for me, I sleep well knowing that 99.989% of the Antarctic ice cap is still there. And even if the loss rate of 1992 to 2017 continues for a total of 250 years, 99.89% of it will still be there.
Additionally, we must respect forces beyond our control. We have no idea whether the melt rate will remain the same, accelerate, or decline over the next century or two. That’s partly because we have no idea what energy mix the nations will use, and partly because it will be controlled primarily by natural factors like cyclical changes in
- solar irradiance, the amount of energy emitted by the sun, which affects earth’s temperature;
- solar magnetic wind , which modulates the influx of cosmic rays, which in turn affect the formation of clouds, which modulate earth’s temperature; and
- ocean currents like the proverbial El Niño/Southern Oscillation, which affects not only weather and hurricane formation along the Gulf of Mexico but also temperature worldwide.
But changes in atmospheric temperature aren’t all the forces that affect Antarctic ice formation and depletion. Volcanism is an uncontrollable threat to Antarctic ice. Indeed, there are at least 91 volcanoes in Antarctica alone.
Jesus certainly encountered those who would abuse others via political power as they strained to enforce inconsequential self-righteousness standards against others, but were willing to swallow whole systems of human cost to maintain their control of the populace.
Blind guides, who strain out a gnat and swallow a camel! Woe to you, scribes and Pharisees, hypocrites! For you cleanse the outside of the cup and dish, but inside they are full of extortion and self-indulgence. (Matthew 23:24–25, NKJV)
Are our environmental standards a blessing or a curse? Are we, including scientists who are still human in spite of rumors to the contrary, deceptive in our pursuits of government financial grants?
Swallowing the Paris Climate Agreement, or any other global warming mitigation measure, to add 0.011% more ice to Antarctica for future generations is a straining not worthy of consideration.

Peta’s Fantastic Plan.
Unlimited Green Energy (yellow actually, read on)
Save the World.
Peta iz going to visit The Sun and bring home some that Hot Stuff.
(Someone else is already doing it, hence Sunspots. Those are actually quarries for mining energy. Seems plenty left though)
Sol is hot and rockets are, shall we say, not that reliable and a tad on the expensive side.
We will build a bridge.
(see how I passed the buck there. tiz The Modern Way. They get to pay too. ha ha)
Sol is still hot so we make this bridge using ice. Good plan so far.
Needs to be big and strong so we make it two miles wide and one mile thick.
All the way from Drax to Sol.
Nice.
Someone once burst Peta’s bubble by suggesting that Sol would vaporise the bridge inside one second flat.
Is that right……
Jim Hawthorne, an LA radio personality of many years ago, once proposed sending an oxcart to the sun, as cited in school textbooks for an example of how long it would take to get there from here.

I reckon Thor and Loki could do it with their portal bridge.
No ice needed.
No less a fantastic idea than AGW.
Damn! Just introduced the Fantastic Four into the equation. Rethink required, I’ll get back to you.
I wonder if sea levels did rise significantly that would mean the surface of the ocean was dramatically expanded. A significantly larger ocean surface area would certainly affect the climate. Have any of the modelers actually considered that? Since they seem to have tried to ignore the oceans as a major driver of climate I doubt it.
I’ve said it 3 billion times, I don’t give a straining gnat’s arse what the scaremongers say.
beng135
And I’ve told you 3 billion times not to exaggerate!
I seriously doubt that we can measure the total amount of ice to that degree of accuracy.
25 years ago that doubt increases astronomically.
MarkW
Nah. S’okay, the greens are experts at measurement. We can trust them.
“In fact, after adjusting for the recent history of solar, volcanic, and ocean current cycles, there was no room left to blame any warming on CO2 increases.”
— That’s because you’re doing it wrong. You have to start with the impact of CO2 that you believe exists, and then back into the other figures. As soon as you’ve fit a formula to the data, you can call it science.
Keith Henderson claims it is impossible to understand the meaning of total Antarctic ice loss when it is expressed as 27,000 billion tons over 25 years.. He thinks calling it a trivial 0.011% decrease is more meaningful.
Neither is meaningful. The resulting increase in sea level is meaningful: 7.6 +/- 3.9 mm/25 years or about 3 cm/century. If Keith had cited the abstract, we would have learned more.
The Antarctic Ice Sheet is an important indicator of climate change and driver of sea-level rise. Here we combine satellite observations of its changing volume, flow and gravitational attraction with modelling of its surface mass balance to show that it lost 2,720 ± 1,390 billion tonnes of ice between 1992 and 2017, which corresponds to an increase in mean sea level of 7.6 ± 3.9 millimetres (errors are one standard deviation). Over this period, ocean-driven melting has caused rates of ice loss from West Antarctica to increase from 53 ± 29 billion to 159 ± 26 billion tonnes per year; ice-shelf collapse has increased the rate of ice loss from the Antarctic Peninsula from 7 ± 13 billion to 33 ± 16 billion tonnes per year. We find large variations in and among model estimates of surface mass balance and glacial isostatic adjustment for East Antarctica, with its average rate of mass gain over the period 1992–2017 (5 ± 46 billion tonnes per year) being the least certain.
[5 +/- 46 billion tonnes per year? Please verify your typing. .mod]
The estimates of ice loss are a dreamscape of imagined pluses without the minuses and are also at odds with many other research findings. Hence, there is NO definitive link to sea level rise whatsoever, said sea level rise being likewise uncertain in the extreme due to inherent difficulties in accurate measurement.
Many of us consider all this to be excorsizing ourselves and our pocketbooks over the Earth’s natural to-ing and fro-ing, and a complete waste of time. It would be a complete waste of talent also, but we see none of that!
John: 27,000 billion tons of ice, when melted, is enough to raise sea level an average of 7.6 mm – fairly negligible. The estimate of 27,000 billion tons of ice lost could easily be very wrong, but the conversion of tons to mm is not – at least in terms of SLR averaged over the globe.

The only people affected by sea level rise are the ones who bought seafront properties as an investment.
Anyone else will move inland and abandon their properties.
Therein lies the foundation of the AGW scam. The Di Caprio’s and Gore’s scare everyone away from their beach-side properties, and they live in idyllic isolation.
Some people have bought seafront properties as investments even though they are aware of the threat that storms pose and and SLR will increase. In the US, this is often possible only because government subsidized flood insurance makes it safe for banks to loan money to finance such purchases. However, only a small fraction of the people potentially threatened by rising SLR are rich American investors who have moved knowingly moved into dangerous coast. Take Bangladesh, for example. Or the non-affluent who live in the lowest areas of New Orleans. Or the Dutch. Or those who live on atolls. Almost all major ports have some endangered areas and many of our biggest cities are ports.
Given that sea level rose 120 m due to roughly 5 degC of warming at the end of the last ice age, significant future SLR seems unavoidable. However, most SLR might not arrive for centuries, which offers plenty of time to adapt.
Normal measurement uncertainty is set at two standard deviations, but 7.6±7.8 millimeters doesn’t sound very scary.

Frank replies: I copied and pasted the words directly from the abstract. It means that the confidence interval is much bigger than the central estimate. Nothing wrong with that scientifically, but it means that the central estimate isn’t different from zero.
I found an article from the CBC in mid June which states three trillion tons in that period. Which is correct, three billion or trillion?
Either is no cause for concern, but if there is a mistake it is a rather large error.
Alarmingly, or not, no one can say!
The important thing to remember is that “alarmists” are not trustworthy:
“someone who is considered to be exaggerating a danger and so causing needless worry or panic.”
One ton of ice is about 3 feet by 3 feet by 3 feet.

Imperial or metric?
I presume imperial from your post, but some smart arse is bound to swan up and criticise you for your comparison.
I put “about” there to cover my bases…
Keith Henderson,
This is an excellent essay! It puts things in perspective!
Perspective will deliver the final blow on CAGW as well as anything else where putting things in perspective makes one think.
Analogies and perspective is a mainstay of my communication.
eyesonu
What’s my perspective of your height?
I can make a fair assessment in feet and inches (or cm if you’re so inclined) assuming I’m provided unadjusted measurements. And of course, the full facts relative to your environment, race, diet, parentage, exercise regime and, of course, posture.
Sorry, just feeling a bit pissed off tonight.
Effing banks!……If there is such a thing as AGW, I damn well hope they suffer first, and worst.
You leave me confused. I am shorter than the WTC while standing at ground level. I’m taller than the piss ants on the walkway. But that would not matter if we were discussing the distance to Jupiter.
The [unethical] omission of facts ready at hand, to the sole purpose of leaving the reader with insufficient data to make their own assessment… is one form of what I call statistical malfeasance.
Another popular tactic is to take some tiny likelihood or risk-percentage of disease or death… especially something whose true value is lost in noise or dispute… call the issue a global or national threat for the sole purpose to leverage it into the entire population to obtain an integer number of deaths of diseases. These integral maladies are then emotionally ‘canonified’, by which I mean the presenter is given free reign for depart from any discussion of method and monopolize the presentation with a purely emotional narrative. For example, spice it up by applying standard population ratios to obtain a hypothetical-upon-hypothetical count of dead babies. Top it off with a stock photo of… a baby.
Another is a manifestation of threat in which the threat is assured and inevitable beyond doubt, is not regular like clockwork, and yet we have no Monte Carlo clue as to when it will happen. So to belittle such an existential threat — which I consider to be a form of mental disorder — the presenter calculates a ‘daily probability’ based on time span since it last happened. The object may range from salving one’s (extreme) fear that it is likely to happen today… all the way to advocating that worry be shelved entirely and no action be taken, and they always have something in mind they’d rather you do first. There is NO assured future in this, but it would surely be no one’s fault when it does happen.
I thought that recently Antarctic ice was gaining in volume. Can’t seem to find the recent ref.
(because of more snowfall). etc.
