Working Group 1 identifies, assesses and models key interactions that regulate the state of the planetary (i.e., the physical climate system, the cryosphere, oceans, terrestrial biosphere systems, cycles of water, nutrients and carbon), and human systems. This informs setting targets for a stable and safe planet, and helps us in developing and understanding pathways that are compatible with these targets.
