The BC3 Basque Centre for Climate Change opens a competitive call for applications for predoctoral fellows in the context of the María de Maeztu award. The fellows will contribute to the BC3 Strategic Plan (2018-2021). This Strategic Plan is aligned with six objectives and two cross cutting themes, which include a further step moving towards solutions co-designed with decision makers in the post-COP21 and Sustainable Development Goals world (transdisciplinary science).
