The results? The group says Arrakis is pretty practical and habitable, for the many part. “We might need to sometimes suspend disbelief, but much of Arrakis itself would indeed be habitable, albeit unwelcoming,” they compose.
There are some noteworthy distinctions in between Herberts Dune and the modelled Dune, especially when it concerns cities. The cities of Arrakeen and Carthag are nearer the polar areas, and conditions there must be more hospitable according to the books. Not according to the design.
The design produced highs of about 45 Celsius in the tropics, which is hot however not a deal-breaker. In the coldest months, the tropics didnt drop listed below 15 C. Both those conditions are similar to Earth.
The modelled Arrakis produced its most extreme conditions in the mid-latitudes and polar areas. Summer season temperatures there reached a bone-scorching 70C in the design, with winter temperatures dropping to -70 C in the polar regions and -40 C in the mid-latitudes. The most affordable temperature level recorded on Earth was 89.2 C in 1983 at Vostok, Antarctica. Earths greatest taped temperature is 56.7 C, which was taped in 1913 at Death Valley in California.
Greater temperatures in the polar areas rather than equatorial regions are counter-intuitive to our experience on Earth. “However, in the model, the polar areas of Arrakis have significantly more atmospheric wetness and high cloud cover which acts to warm the climate since water vapour is a greenhouse gas,” the authors describe.
In the world of Dune, the planet Arrakis is seriously crucial. Its the just known source of the resource called spice melange, a psychedelic drug which when utilized by the space navigators guild permits them to take a trip between stars. Dunes severe conditions make the spice challenging to harvest.
Dune is a desert world, where it never ever rains according to Herbert. The environment is so extremely hot that anyone who ventures out into the Sun need to use a stillsuit– which cools the body and recycles the bodys moisture– or face death.
The trio of researchers wished to take a look at the imaginary Dune to see how realistic it was. To do that, they relied on present environment models. Instead of publish a paper, they presented their results in a post at The Conversation.
” We required a big supercomputer to be able to crunch the numerous countless computations required to mimic Arrakis.” From “Dune: we simulated the desert world of Arrakis to see if people could make it through there.”
A world can be both unwelcoming and habitable, much like severe environments here on Earth. The concept of an individuals like the Fremen adapted to an extreme environment like Arrakis is no stretch.
The group utilized the physical laws here on Earth as their basis, otherwise, it suggests that Dune is a complete fantasy world. With the physical laws comprehended, the group then spoke with the in-depth descriptions of Arrakis in Herberts 6 novels and in the Dune Encyclopedia.
Then they input information like the worlds topography and height of mountains, and the amount of sunshine reaching the surface area. They also input Arrakis orbit, which is nearly circular similar to Earths. The authors make special mention of the orbit, which can severely influence environment. “The shape of an orbit can actually impact the climate: see the irregular and long winters in Game of Thrones,” they write.

Dunes atmosphere is comparable to Earths, except for CO2. Its at 350 ppm rather than Earths, which is presently around 413 ppm.
The ozone is different, too. Earths ozone is in the upper atmosphere with very little in the lower atmosphere. Overall, Earths atmosphere is only about 0.000001% ozone, while Arrakis atmosphere is about 0.5%. This makes good sense given that ozone is more efficient at warming the atmosphere than carbon dioxide is.
With the environment design inhabited, the team awaited an effective computer system to run it. “Complex designs like this take time to run, in this case, more than three weeks. We needed a big supercomputer to be able to crunch the hundreds of thousands of computations required to mimic Arrakis.”.
As part of their results, the trio of researchers produced a visual climate model of Arrakis.

Herbert produced a planet with no rain, however the design didnt reproduce that. Rather, high-altitude regions in the upper latitudes did get seasonal rain. Not really much.
Herberts Dune also has polar caps, but the design was unable to replicate those. That distinction is the largest one according to the authors. “But this is where the books perhaps differ the most from our model, which recommends summertime temperature levels would melt any polar ice, and there would be no snowfall to replenish the ice caps in winter season,” they compose.
So, is the imaginary Arrakis in fact habitable? Yes, but not in the way the fictional inhabitants live there. Arrakis is a harsh world to endure on, but its possible.
In their conversation of habitability, the authors assumed that the fictional humans on Dune and we non-fictional people on Earth have the same heat tolerance. In that case, the tropics are the most habitable, rather than the polar regions.
The planet Arrakis is pretty reasonable for something developed in the 1960s. The designs say thats not practical. The mid-latitudes have monthly-average temperature levels that typically go beyond 50– 60C in the lowlands, with daily maximums reaching higher than that.
Herberts Dune has no rains and no bodies of water, so something like a stillsuit, which recycles wetness and cools the body, is needed. In any case, much of Dune is both too hot and too cold for humans to live without technological defense from the extremes.
This work is an excellent little fun, and the authors make it clear that they did this on their own time. They say that for his time, Frank Herbert did an excellent task of making a fairly believable planet, without the advantage of the climate science and computer systems and exoplanets that we have today.
Their final paragraph: “Its important to bear in mind that Herbert composed the very first Dune novel method back in 1965. This was 2 years before recent Nobel-winner Syukuro Manabe released his critical very first environment model, and Herbert did not have the benefit of modern-day supercomputers, or certainly any computer. Considered that, the world he developed looks incredibly constant 6 decades on.”.
The 3 researchers behind this effort are Alex Farnsworth, Michael Farnsworth, and Sebastian Steinig.

Science fiction author Frank Herbert is renowned for the richly-detailed worlds he developed. None of his work is more widely known than “Dune,” which took him six years to complete. Like his other work, Dune has plenty of detail, consisting of the description of world Dune, or as the Fremen call it, Arrakis.
Dune is an unforgiving desert world that suffers powerful dust storms and has no rainfall. Researchers who focus on modelling environments set out to see how reasonable Dune is compared to exoplanets. Their conclusion?
Frank Herbert did an excellent job, considering he produced Dune in the 1960s.
