Building Earth
Interactive climate simulation built from first-principles physics
Visit earth.crackalamoo.com ↗What is Building Earth?
Building Earth is a browser-based 3D climate simulator that constructs Earth's climate system from the ground up, starting with sunlight hitting bare rock and progressively adding physical processes. Each layer of physics is introduced separately so you can observe how atmospheric effects, radiation, and weather patterns emerge.
Designed for anyone curious about climate science, the tool uses fundamental constants and elevation data rather than machine learning. An integrated language model analyzes simulated data and explains the physics at work. The maker says it was built over six months almost entirely with Claude Code, using Claude Opus 4.6.
