How to Code a Climate Spiral
2,482Learn to create your own climate spiral using p5.js and temperature data. Originally designed by the climate scientist Ed Hawkins, the climate spiral is a visual representation of the changing temperatures over time, illustrating the urgent need to address climate change.
