Earth system models represent our best tool to predict and prepare for future changes to Earth’s environment. However, the immense computational cost of running these models at high resolution limits their ability to make regional projections at fine scales. Indeed, a typical limiting scale for these models is comparable in size to the island of Hawai’i (~100 km). Obtaining more granular projections, for instance at the city level (~10 km), is critical for planning everything from farming...
