Did you know that Venezuela’s last glacier was just demoted to an icefield? Or that this tropical, nearly equatorial, nation even had glaciers? [emphasis, links added]
Well, it was and it did.
And a reader asked us how to answer an alarmist claim that the demotion proves there’s a man-made global heating crisis, which of course is being bleated in unison by the herd of independent media minds around the world, none of whom of course hitherto knew or cared that said glacier even existed until it afforded this week’s opportunity to bang the climate apocalypse drum.
To which we said, as we usually do, check how long it’s been melting, because as a rule, the shrinking of glaciers demonstrates not that man is warming the planet but that the planet is warming man.
Then, and yes in true scientific fashion, we checked it ourselves to see if our hypothesis was sound. Si señor. It most certainly is.
The thing’s been melting since before World War I, most of the melting happened before World War II, and whenever the man-made climate breakdown thingy hit, surely it wasn’t 1938.
The ex-glacier in question is the Humboldt Glacier, “struggling for survival in the Sierra Nevada National Park” according to the Times of India. Brave glacier! (And not to be confused with Greenland’s “Humboldt Glacier“.)
Mind you the South American one is not going to make it, given that Venezuela is not merely tropical but very nearly touches the equator, and is not a major mountaineering destination because its highest one, Pico Bolívar (not to be confused with Colombia’s Pico Simón Bolívar, a massive 5,730 meters high) tops out at just under 5,000 meters above sea level (4,978) and the ice field in question is on Pico Humboldt (please give now to alleviate the name shortage) at 4,925 meters.
Not where you’d store your ice if you cared about it.
Euronews.green complains that:
“Venezuela has lost its last glacier, making it the first nation in modern history to hold this unenviable record. At least five other glaciers have disappeared in the South American country within the last century as climate change drives up temperatures in the Andes. The country lost 98 per cent of its glacial area between 1952 and 2019, research shows.”
Note again that climate change is some weird mystical thing that surrounds us and penetrates us and causes temperatures to rise. It is not a description of them doing so. And of course when “research shows” mere citizens fall silent.
Despite this we did go and look at the actual research and, persevering down to Figure 5, found this map proving we were completely right all along and these journalists don’t know how to fact-check:
It’s a nice piece of work graphically speaking, with bright colors easy to follow, based on a reconstruction of the various glaciers going back to 1910, and the key here is that all the purple stuff is what melted between 1910 and 1952.
Big splotches, aren’t they? And look at the other two areas: they were half gone by 1952 and dwindled to specks or vanished by 1998, a full 26 years ago (the blue stuff being what vanished between 1952 and 1998). Showing crucially that major melting started over a century ago, at a minimum.
We don’t know what happened before 1910 because ice doesn’t leave much in the way of a fossil record.
The pattern of Venezuelan glaciers is not anomalous. Rather, all glaciers have been retreating for centuries, with most of the melting predating the recent past.
Where we know in more detail, most of it happened before the 19th century. For instance, look at the map of Alaska’s famed glaciers published by W.S. Cooper in 1923 (below) and compare the ice extent in Alaska’s Muir Inlet as of 1880, compared to 1916. Or the Reid and Torr inlets from 1879 to 1916:
Or, for a prettier version, look at this 2013 brochure given to one of us when we visited:
Look at the ice in 1750 and 1880, and then from 1880 to today. There was some mighty climate change back in George Washington’s day, that’s for sure. Caused by climate change, no doubt.
But not by us and our horse-drawn buggies. As is also true of the Franz Josef Glacier in New Zealand, in case anyone tries to tell you the Little Ice Age was regional.
All of this does not prove that something weird started in 1958, 1988, or 2000, or whatever the alarmists currently claim. On the contrary, it proves the exact opposite.
We are in a long-term warming trend that is overwhelmingly natural unless you believe that human CO2 not only causes artificial heating but shuts off the natural kind through some hitherto unknown process incompatible with the laws of physics and chemistry as we know them.
People get it wrong all the time because they’re so dogmatically certain that they do not check either facts or reasoning.
As we noted back in 2020, claims that the shrinking of France’s largest glacier was “irrefutable proof of global warming” were dead wrong. It was the opposite.
The glacier had grown dramatically in the 18th century, peaked around 1850, and then shrank dramatically.
Glacier disappearance goes back much farther than 1800, too. As one paper safely published back in 1992 put it, concerning Hannibal’s apparently eccentric decision to bring elephants through the Alps:
“By the 3rd century BC the Alpine glaciers were in a backward position compared with their position in 900-350 BC. This fact and the mildness of the climate, inferred from tree-ring analyses, suggest that ice conditions were not severe in the Alps in 218 BC.”
And the two main primary sources, Livy and Polybius, stress the appalling geography of whichever pass or passes he used but do not mention ice or glaciers. So possibly some countries that now have at least residual glaciers did not then. Which again rather proves our point.
Nowadays everybody’s so sure of the opposite that they find it whether it’s there or not. The research that says claims that:
“Glacier retreat in mountainous regions has accelerated worldwide within the last fifty years, triggering efforts to document what will soon become legacy landscapes (Barry 2006; Zemp et al. 2015; Huss et al. 2017). In the tropical Andes, the rate of glacier retreat after 1950 is above the world’s average, with a notable increase after 1970 (Rabatel et al. 2013; Veettil and Kamp 2017).”
And nobody saw it coming that the place they were studying would be going up in flames faster than the average. But the rest of the statement is also nonsense.
They have no idea what the rate of retreat of the glaciers in this region was before 1900 so they can’t compare it to the present.
Besides what “rate” are they talking about? Distance? Volume? Percentage? If the latter it’s a cheat, because of course as it gets smaller, the rate of percentage decrease will accelerate.
But as we’ve shown before, only an insane person would maintain that the rate of glacier retreat in Alaska’s Glacier Bay National Park was slower 200 years ago than recently, or that it doesn’t have mountains.
Wikipedia predictably claims that:
“Most of New Zealand’s large glaciers shrank significantly towards the end of the 20th century, a consequence of global warming.”
But after that ritual genuflection, it blurts out that:
“Franz Josef Glacier advanced rapidly during the Little Ice Age, reaching a maximum in the early 18th century. When Haast became the first European to see the glacier it was still much longer than today, and the ice surface was 300 m higher. Between its first official mapping in 1893 and a century later in 1983, Franz Josef Glacier retreated 3 km up the valley.”
Note the “still”. That mapping was in 1893 and it had already retreated an enormous distance.
Like the Humboldt, it responded to natural warming long ago, and the fact that it still is doesn’t mean the warming suddenly started recently or changed its nature and cause. It means it’s a continuation of a long, natural, cyclical rebound from the Little Ice Age.

More reasons to stop believing the M.S. Media Bottom Feeders
It is well documented that glaciers have been declining before man made climate change was suppose to be a factor. I should point out that this is part of a positive feed back loop though probably not a major one. Ice reflects more sunlight back into space than the soil or rocks under the ice. When the ice melts, more energy remains on the ground. To whatever extent this causes warming, there will be more melting of the glaciers.
Where were they when the last N. American glacier melted? All due to human-caused global warming, back 12,000 years ago?
