Capacity building for advancing climate-change leadership has become a critical workforce development requirement for both professionals and front-line workers. As the World Economic Forum Jobs 2020 report noted, there is an increasing need to provide short-timeframe opportunities for reskilling and upskilling that will keep step with the increasing issues of the climate crisis. Micro-credentials have been proposed as a strategy to enable the ongoing development of knowledge and skills to address this workforce development requirement, which we examine in the context of a university initiative that has prototyped skill pathways to address key climate adaptation themes. We report and discuss the strategic use of the Climate Adaptation Competency Framework (2020)--a Creative Commons-licensed (CC) open competency framework--along with the use of open educational resources to create agile pathways to skill development for climate adaptation and action. The pathways we have designed and are testing combine self-directed learning resources, individual and group activities, and authentic assessment practices to validate skill development. Micro-credentials are awarded from a university continuing and professional studies division to learners from multiple practice domains for demonstrations of competence.
