The WCRP Climate Science Week, taking place this week as part of the American Geophysical (AGU) Fall Meeting, began with a Joint Early Career Researcher (ECR) Workshop on Water Cycle in a 1.5° Warmer World: Interdisciplinary Approaches. The workshop attracted 44 early career researchers, from many disciplinary backgrounds and geographical locations, who discussed fundamental science - interactions and feedbacks; uncertainties in near-term predictions to projections and future evolution; and impacts and implications for society - themes from the Intergovernmental Panel on Climate Change (IPCC) Working Groups I, II and III. Participants also discussed, together with representatives of the WCRP leadership, how ECR research and ideas can best be integrated into the new WCRP Strategic Plan. The outcomes of the meeting will provide input into discussions on the implementation of the WCRP Strategic Plan and will be presented by Gaby Langendijk at the WCRP 40th Anniversary Symposium (Sunday 8 December 2019).

The workshop was jointly organized by the Young Earth System Scientists (YESS) community, the Young Hydrologic Society (YHS) and the Association of Polar Early Career Scientists (APECS).
