    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.

    2. Has your local climate gotten noticeably warmer in your lifetime?

      I was just thinking, it does seem that where I am summers and winters are hotter than they used to be (I'm in the northern Midwestern US). Actually this winter we had a few days where it got over...

      I was just thinking, it does seem that where I am summers and winters are hotter than they used to be (I'm in the northern Midwestern US). Actually this winter we had a few days where it got over 60 degrees(!) and I do feel like it snows less than when I was a kid. But I've only been alive for less than 2 decades and I don't think the global temperature has actually risen a lot in that time? So I'm curious, has anyone else personally felt the affects of climate change in their own climate? And if so, since when?

      edit: I also remember seeing lots of fireflies when I was younger. Haven't seen one in years.
