Temperature slider drives real satellite data visualization better than static climate maps.

Strengths

•Per-pixel rendering from actual elevation and satellite data, not fake graphics
•Honest methodology docs admit models are approximations tuned for visual accuracy
•Click-anywhere snowfall projections add useful local context to global view

Weaknesses

•Author admits these aren't proper climate simulations, limiting scientific utility
•Climate visualization space already has NASA, Climate Central, and academic tools

Post Description

I built an interactive 3D globe to visualize climate change. Drag a temperature slider from -40°C to +40°C, set a timeframe (10 to 10,000 years), and watch sea levels rise, ice sheets melt, vegetation shift, and coastlines flood... per-pixel from real elevation and satellite data.

Click anywhere on the globe to see projected snowfall changes for that location.

I'm an amateur weather nerd who spends a lot of time on caltopo.com and windy.com tracking snow/ice conditions. I wanted to build something fun to imagine where I could go ski during an ice age.

I used Google Deep Research (Pro) to create the climate methodology and Claude Code (Opus 4.6 - High) to create the site.

The code: https://github.com/travistruett/terrashift

The models aren't proper climate simulations, they're simplified approximations tuned for "does this look right?" but more nuanced than I expected them to be. The full methodology is documented here if anyone wants to poke holes in it.
