  Datafication -- the increase in data generation and advancements in data
analysis -- offers new possibilities for governing and tackling worldwide
challenges such as climate change. However, employing new data sources in
policymaking carries various risks, such as exacerbating inequalities,
introducing biases, and creating gaps in access. This paper articulates ten
core tensions related to climate data and its implications for climate data
governance, ranging from the diversity of data sources and stakeholders to
issues of quality, access, and the balancing act between local needs and global
imperatives. Through examining these tensions, the article advocates for a
paradigm shift towards multi-stakeholder governance, data stewardship, and
equitable data practices to harness the potential of climate data for public
good. It underscores the critical role of data stewards in navigating these
challenges, fostering a responsible data ecology, and ultimately contributing
to a more sustainable and just approach to climate action and broader social
issues.
