About the game
World Climate Lab is a real-time planetary climate simulator. Import your own terrain or sculpt a world in the topography editor, then watch a living climate emerge from physics: winds, oceans, cloud bands and ice. Every climate is calculated, not painted.

AI Generated Content Disclosure
The developer filed this on the Steam store page. It is not a guess by active.games.
AI was used to help localise languages I do not currently have resources for (Russian, German and Chinese), but will be entirely human by full release once the final UI and text are finalised.

Settle starts from the world’s own star, tilt and orbit. Cool-star worlds no longer begin 20 degrees too warm; strongly tilted worlds no longer begin with Earth’s pattern; a world far from balanc…

World Climate Lab 0.1.8 update (opens in new tab)
