This post was inspired by a post by a friend (sharing the news article) and a response by one of his friends. To be clear, I don’t think this friend was a MAGA. But I do think that Dunning-Kruger was strong with him. There were so many factual errors that I strongly considered replying (usually a bad idea - the whole “answer a fool according to his folly” thing.) However, I was in the middle of a concert week and had better things to do.
Instead, I decided it would make an interesting blog post, particularly since I am in the middle of a bunch of books but haven’t finished one recently. Also, because I care a LOT about maps. (See below.)

So, here is the kerfuffle. The United Nations recently passed a resolution encouraging the replacement of the Mercator Projection with the Equal Earth projection. And also to teach that no projection can accurately represent the sphere of the earth. This isn’t a mandate. It is just an encouragement to schools and other institutions to make the change.
The reason for this is pretty clear: the Mercator Projection distorts the relative size of continents and countries, making those in the north (such as Europe, Canada, and Russia) substantially bigger than they are, and those near the equator (particularly Africa but also South America) look significantly smaller.
In practice, this has led to widespread belief that Africa is smaller than the United States or Europe.
[True story: during the last Ebola outbreak, my wife had to calm some staff down about the admission of a visitor from the opposite side of Africa. People have no idea where the countries are anyway, but also failed to realize the vast distance between eastern and western Africa.]
While a handful of eastern European countries abstained from the vote, the only no vote was….the United States.
Because we are currently led by a pack of vicious racists, they whinged that this was a “radical ideological project.” Because of course they did.
And yes, this is totally embarrassing for many of us Americans.
But, the right wing here is nothing if not completely allergic to change, and if the Mercator was good enough for their grandparents, gosh darn it MUST be preserved for eternity.
And also: racism.

Before I dive into the debunking of the misinformation this guy posted, let me establish my bona fides for this topic.
I have loved maps since I was a small child. Our house always had a globe and a variety of maps, and I spent many hours with them.
I grew up in the Los Angeles area, and, for anyone of my generation, we had a Thomas Guide. This was a spiral-bound book of street maps for Los Angeles County. (You can also get them for Orange County and San Diego County.) If you can drive there, it’s on these maps. I poured over them regularly as a child.
Because of this, from the age of about 12, I could draw the Southern California freeway system from memory. I probably can still do that. I also was able to name all the primary and secondary streets of the San Fernando Valley in order, south to north, and east to west. I’m a bit out of practice on that one, since I haven’t lived there in 35 years. Well, I can probably still do the primary streets.
Also around this time, my brother and I created an entire neighborhood which we drew on paper. As in, every street, house, business. If we laid out all the pages, it was probably bigger than our house.
Anyone who has traveled with me knows I have a strong sense of direction. On a clear day or night, I quickly orient myself to cardinal directions, and can think in terms of a map - I absolutely have a map in my head wherever I go.
Same thing hiking in the wilderness. I usually bring a map and compass, not a GPS, and I am oriented to where I am at all times. On several occasions, I have done route finding off trail with others, and I’m generally the one who knows where to connect to other trails.
Even though I do use navigation software at times, I really prefer paper maps, and will tend to study routes in advance so I know where I am.
All this to say that I care deeply about maps and have since childhood. I know a good bit about them, can use them (including map and compass navigation), and have spent a lot of time thinking about things like projections for literally decades. I’m not glomming on to recent news and conjuring up an opinion.
I should also mention that my brother has been on a one-man anti-Mercator crusade for decades. So believe, me, I have heard all the arguments for or against all the major projections. For what it’s worth, I kind of like the Goode Projection, because it’s a bit quirky and also preserves shape and size remarkably well.
Also, here is a plug for Simon Garfield’s delightful book, On the Map. Check it out.

So, on to the debunking.
Misleading claim: The Mercator Projection is useful for navigation
This is at best a half truth, but is misleading.
First, the history.
Belgian mapmaker Gerardus Mercator first created the map in 1569. His intent was to provide a better map to be used by sailors in transoceanic voyages. And it worked pretty well for its time in history.
The basic idea was that you could follow straight lines of latitude across the ocean.
So, the true part of this is that the Mercator Projection was once useful for transoceanic sailing using a map, compass, and sextant.
It had its flaws, however, one of which was that it was actually ahead of its time. While the technology of the time could accurately determine latitude, there was no great way of determining longitude.
It’s not that people of the 16th Century didn’t know how to do this. You simply need an accurate way of determining global time. But creating a reliable and accurate clock that would work in extreme conditions such as violent weather at sea was devilishly difficult. In fact, the chronometer wouldn’t be created and used until 200 years after Mercator created his map.
Once this happened, global travel exploded: the golden age of sail that has inspired literature and art ever since.
I’ll also recommend reading about Nathaniel Bowditch, one of my heroes, who was instrumental in creating detailed star charts and calculations for navigation. Oh, and he also was a big deal in the areas of trust, insurance, banking, and higher education. Seriously, one of the greatest men few have heard of.
[Side note: the fact that the Polynesians managed to navigate accurately long before Europeans, and without modern technology, is astonishing. It required huge amounts of memorization as well as skill in reading the ocean and atmosphere.]
So, here is where the claim is misleading:
The Mercator Projection was once useful for a specific kind of navigation: transoceanic voyages using compass, sextant, and eventually a chronometer. It was never useful for terrestrial or coastal navigation - for those you need a detailed map of the particular area, not one with straight latitude lines.
These days, literally no one uses the Mercator Projection for navigation. It is beyond useless for the Great Circle routes our aircraft fly. And, for that matter, the routes our ships travel. Straight lines on a globe are not straight on a Mercator-based map.
So, the better way to put this is that the Mercator Projection used to be useful for navigation, but has been outdated for, well, at least a century.
False claim: All of our current maps, including computer navigation, are based on the Mercator Projection
This is straight-up bullshit.
To even claim this shows a gross ignorance about maps, mapmaking, and projections.
Here is a somewhat oversimplified version of what mapmaking does:
When taking a spherical earth and converting it to a flat map, the first thing you have to do is determine where you are going to center it. Basically, put a pin where the page touches the sphere. At that point, the map is accurate for both page and ball, and as you get further away from that point, it gets increasingly inaccurate.
For Mercator, his map touches the globe at the equator. As the map gets further from the equator, it gets increasingly inaccurate.
When mapmakers create maps for smaller areas, they don’t just cut a piece of the Mercator projection. They instead pick a center, and work outward from there.
This is blindingly obvious if you have ever spent time with an atlas or with maps in general.
Seriously. Go get yourself a map of a state like, say, Colorado. Here is one from Britannica.
Notice anything weird about it?
Oh yes, it isn’t as rectangular as a Mercator map would make you believe.
Instead, the top and bottom curve a little, and the top is narrower than the bottom. Why is that?
Well, the lines of latitude are not actually straight on a globe. They curve. And the lines of longitude aren’t parallel at all. They converge at the poles.
This map is, in a very real sense, more accurate than a Mercator map would be. It better represents the actual shape of the state of Colorado, and is thus better for actual navigation.
My guess is that to make this map, the mapmaker put a pin in the middle of the state, and worked outward from there.
Again, anyone who has spent any meaningful time with an atlas would know this - every state is drawn to be as accurate as possible. Same thing with the United States, which displays the same curves and corrections in any good map.
The exact same idea is how our digital navigation maps work. Except they constantly readjust the center to be where you are at any given time. (That’s literally the basis for GPS mapping - it is a three-dimensional map of the globe, and the computer calculates where you are and draws the area around you.
It is easy to miss the way GPS maps work, because they display such a small area. The curvature of the earth is pretty negligible at a smaller scale - if I build a table I don’t have to account for it at all. But the towers of the Golden Gate Bridge are nearly two inches further apart at the top than the bottom. A few inches is not noticeable on a map covering a couple miles at most. But I can tell you that GPS apps do not distort more and more as you go toward the poles. They simply re-center and adjust.
This is precisely what the Mercator Projection does not do.
A second issue here is the claim that “nobody is switching their GPS maps to the Equal Earth Projection.” Of course they aren’t. Global projections aren’t used for local maps. And nobody is or ever has used the Mercator Projection for local maps either.
This is a red herring and a distraction from what the UN resolution actually is about. It is about which projection is used for teaching and other places where a global projection is needed or useful. It has nothing to do with local maps or GPS software.
False claim: The Mercator Projection accurately shows shapes, unlike other projections
Again, clearly bullshit if you actually know maps.
Every projection distorts shapes to some degree, and the Mercator Projection is actually one of the worst.
It’s not like Mercator didn’t try to compensate - he did so by expanding the latitude lines toward the poles so that the vertical dimension got bigger along with the horizontal dimension.
But that doesn’t actually preserve accurate shapes.
On a Mercator map, a rectangle would become a trapezoid, bigger at the top than the bottom (in the northern hemisphere.) Check out the difference between how Russia (to use an example) looks on a Mercator projection compared with a more accurate map using Russia as the center pin. It’s not even close.
Now, take a look at the Equal Earth Projection. It is actually quite a bit more accurate as to shape than the Mercator. Perhaps the main objection is that at the edges, it gets a bit less accurate. Meaning the United States, of course. But one could center the map wherever - and online versions let you spin the globe, so to speak.
For nerds: yes, the Equal Earth Projection is based on the Robinson Projection, but compensates more to preserve relative size. This means a bit of elongation for some areas of the map. Again, every projection distorts to a degree. The Mercator is one of the worst offenders.
Misleading claim: Digital maps have mostly replaced printed maps
This is at best a partial truth. Yes, most people these days rely on GPS navigation apps. I think this is a horrible development in that fewer and fewer people seem capable of orienting themselves without a device. Heck, it seems most people can’t even walk in an unknown city without staring at their phones to get around. If the networks go down, there are going to be a lot of lost people. Sigh.
Anyway, the point of the UN resolution isn’t to replace digital maps (which don’t use the Mercator Projection anyway - see above), but to replace the global maps we use for teaching.
Come on, all of us had maps in our classrooms, right? And my kids seem to have them in theirs. From a young age, all of us are taught about the world, and a map of the planet is a part of that.
I think globes should be used more too, but they are bulky and more easily broken (and more expensive to replace) than a laminated paper map on a wall.
The UN does have a point here too: the use of the Mercator Projection has indeed created generations of people who think Canada is far bigger than Africa. In subtle ways, this leads to implicit bias in how we think of the world and how we should view the other humans who live in it.
Is a new map going to fix everything? Of course not. Neither is accurately teaching that projections are only approximations of three-dimensional reality. But they are a small change that can nudge our thinking.
Which is, of course, why the Orange Fascist and his government are stoking outrage about it. Anything that might possibly make black people look more important infuriates them.

I am also puzzled by the faux-outrage about this. My parents were and are pretty right wing, but we were taught accurate information about globes and maps and the relative sizes of the continents. It wasn’t even controversial.
These days, however, anything, no matter how innocuous, that in any way challenges white supremacy, triggers right wingers. Even attempts to bring our maps forward 450 years.
Because of this, I want to address two more of the false claims in that comment.
False Claim: There are real injustices that need addressing, so we shouldn’t be talking about maps
I am so sick of this distraction and redirection.
First, it is possible to work on multiple problems at the same time. One can work on smaller, more symbolic issues at the same time one works on addressing larger injustices! Seriously.
Second, I find it interesting who the people are that keep harping about how we shouldn’t spend any time on symbols are. As in the case with this guy, it is pretty much always white people. Who dismisses the removal of Confederate monuments as meaningless? Pretty much only white people. And usually white men.
This is what you get when the symbolism of our world almost entirely glorifies you and people like you. You don’t notice the constant pernicious effects of symbolism. Think of what happens whenever Jesus is portrayed as a color other than white. People flip out, right? Because the symbolism matters.
And that is the point. Symbolism matters a lot more than middle class white guys realize. At least until they see a symbol changed from them to other kinds of people. As Robert Dussey, Togo’s foreign minister, said before the vote:
“Maps shape our understanding of the world. They guide education, nourish the imagination, and influence collective perceptions.”
This is why I think that the argument of “we shouldn’t focus on the symbols” has a significant racist (and sexist and classist, etc.) thread to it. The UN resolution was raised by a group of non-Americans, mostly from Africa.
As I note below, combine this with the “don’t make the racist right wing extremists mad” thing, and it all starts to look like it is more about white comfort than anything else.
False Claim: The UN resolution ultimately hurts the left
This is one of the most idiotic jingoistic piles of bullshit I have heard.
The vote at the UN was 164 to 1. We were literally the only country to object.
What is more accurate to say is that our white supremacist fascist government decided to throw a tantrum about a change to a more modern map, calling it a “radical ideological project.”
The only people who actually think that are apparently….white racist Americans. Full stop. Countries that range from relatively leftist to relatively right wing were fine with the change. It wasn’t even controversial at all.
Only here, where the Orange Fascist and his goons and ghouls are obsessed with ethnic cleansing and American jingoism is this an issue.
And, stay tuned for the book-banning crowd to now go on a jihad against the non-Mercator maps that are in classrooms around our country already.
And you know what? I am so beyond caring what racist right wingers think. Every time we cave to them, we let the Overton Window get dragged ever further rightward. I’ve had enough.
Let’s call this what it is: a racist right wing extremist tantrum. And an absolute embarrassment to our country and most of us Americans.
By opposing the resolution and throwing a racist tantrum, all that has been accomplished is to further convince the rest of the world that the United States is freaking insane and dangerous and deeply stupid. Which, unfortunately, is not inaccurate.
Those of us (like my friend) who are pointing out what an embarrassment this is and that it is a symptom of deep racism and jingoism are not the problem. The racist right wing extremists in our government are the problem. Whether you want to admit that truth or not.

If you like the Mercator Projection, for whatever reason - nostalgia is probably the most likely - go ahead. Feel free to defend it on its merits.
But don’t make misleading or false claims about it. And don’t pull the “we shouldn’t upset racist right wing extremists by calling out their embarrassing bigotry” card.
