Ranges of projected 21st century snowpack loss in the U.S. West. California could experience episodic low-to-no snow as early as the late 2040s and persistent low-to-no snow in the 2060s, according to one high-resolution climate projection. For other parts of the western U.S., persistent low-to-no snow emerges in the 2070s. Graphic: Erica Siirila-Woodburn and Alan Rhoades, 2021 / Nature Reviews Earth and Environment
