    1. If all ice on Earth melts, how will coastlines change? I made a rough sketch with a website and video

      I'm a web developer who got inspired by NASA's imagery (and my abundant climate anxiety) to make an interactive map and video visualizing how sea levels could change if all ice on Earth melts....

      I'm a web developer who got inspired by NASA's imagery (and my abundant climate anxiety) to make an interactive map and video visualizing how sea levels could change if all ice on Earth melts. Most estimates that I've seen for potential sea level rise vary from 60 to 75 meters, some higher. This map shows roughly 65 meters. It's not a scientifically useful tool (there are many good ones!) but I like the result and wanted to share.

      I made it using NASA's Blue Marble Next Generation, topography, and bathymetry. Unfortunately the land imagery is from 2004. Would be interesting to compare it to an updated version. The song is "Winter" by Alexander Nakarada.

      On the technical side it uses WebGL for the map via PixiJS, and Svelte for the rest of the app. I originally wrote it all in Svelte but the DOM isn't up to the task. If you're curious you can switch to the DOM renderer by pressing ctrl+backtick on the map and clicking "webgl". The source code readme has more info.

      I'm happy to answer questions, not about the science though, I just make websites.
