    The title falsly implies that mercator is “incorrect”. Mercator is an angle preserving projection, meaning all angles are true to real life. The “equal earth” map is an area preserving projection, meaning it retains the true area of countries, but in return the angles are all wrong. This makes equal earth unsuitable for navigation for example.

    It is also false to imply that this is some kind of new development. This was very much known all along, mercator simply became the default because world maps used to be primarily for navigation.

      Traditional navigation is so cool, I had to learn the basics of it a few years ago as part of a course I was on. I suspect it’ll feel rather less ceremonial in the future if GPS jamming and spoofing continue to become more common.

      The title is incomplete, but then again the title is already pretty big without being “The UN has backed replacing the 500-year-old Mercator projection with maps that conform to the actual surface areas of the continents, including the Equal Earth cartographic projection, were appropriate”

      how is Canada smaller than the USA in this “equal earth” map when it’s supposed to display true areas? or is the pic in this post just shitty?

        Canada (without the various arctic islands) is considerably smaller than the contiguous (sans Alaska and Hawaii) US.

          It’s bigger even if you include Alaska (and Hawaii, but you can ignore Hawaii because it’s small).

          We’re repeatedly told in school and all throughout our media that Canada is the “second largest land mass in the world”. Is that not true?

            Land mass or country? Because the Americas make us the second largest land mass with Eurasia and Africa because the largest.

              Isn’t Africa connected to Eurasia? So we have the Americas and AfroEurasia plus some islands. Which is why “continents” has no meaning and is another social construct unless you divide them in a way that makes zero sense to anyone who isn’t a geologist.

                We should divide the continents in:

                Continents: the actual land, so we have the Americas (i’d count them as one as they are almost one), AfroEuroAsia

                Sub continents: their definition is cultural so we have north and south america, Africa, Europe, Asia and Oceania

                Don’t take anything too seriously, i thought about this on two feets around 2 years ago and forgot about that until now

                  I know at the end of the day it doesn’t really matter, but it always rubbed me the wrong way when Europeans claim that The Americas are one continent because it’s one connected landmass, but somehow Europe is it’s own continent. North/South America at least came from different super continents and only recently collided. Europe (minus the Balkans) and Asia (minus Arabian and Indian peninsulas) have been together since at least Pangaea.

                Which is exactly why I said Eurasia AND Africa. I also never said continent. I said LND MASS which is what was previously said.

                Work on your reading comprehension.

          Smaller in area?

          According to wikipedia, these are the total areas of both countries:

          USA: 9,833,520 km2 Canada: 9,984,670 km2

          I am certain I am just misunderstanding the system behind this new projection but reading it is supposed to display accurate area, it seems Canada should show up bigger.

          Canada is slightly larger than the US in total area. The US is a tiny bit larger when you just count land-area.

              Canada total area: 9,984,670 km^2

              USA total area: 9,866,624 km^2

              Have a look a the respective 2nd digits of those numbers and consider that 9 is indeed bigger than 8.

                Total land area: 9,093,507

                You are counting ocean as part of Canada, a thing not represented on maps.

                Imagine being this condescending and wrong.

                  No oceans were counted. But the total area does includes lakes and rivers.

                  And I already said earlier that the US slightly larger when you just look at land area. It’s no where near 10% though.

        They look about the same size to me and they should be about the same size. So that checks out.
