“…The authors modified a well-used climate model for exoplanet research and applied it to the planet in Dune. The work was carried out in their spare time and is intended as an appropriate outreach piece to demonstrate how climate scientists use mathematical models to better understand our world and exoplanets…”

Looks like the Kingdom of Jordan to me. 😉

Is Dune scientifically plausible? We ran a climate model to find out.
