Climate models are a main source of future climate information, but they are extremely expensive and slow to run. Studies concerned with the effects of climate change on human and natural systems often need climate information for emissions trajectories not run by climate models. Previously, emulators have attempted to create climate information for these trajectories. However, they usually fall short of the information demands of increasingly sophisticated impact models.

STITCHES, a new emulator, works by stitching together building blocks of actual climate model experiment outcomes to create new trajectories. By construction, STITCHES’ output has the same complexity and richness of climate model output to meet the needs of impact modelers.
