Critically examining research funding patterns for climate change and human health

Many actors have recently launched significant new initiatives in the domain of climate change and health. Given this important nexus, we undertook a review of funding patterns from 1985 – 2022, using the NIH RePORTER database for the United States and the Dimensions database globally. This includes an assessment of more than 9 million publicly funded projects across both databases with a collective budget of more than $3 trillion. We estimate that between 1985 and 2022 only 0.26% of research funding awarded by the NIH related to climate change, and only 0.70% of funded projects in the Dimensions database related to climate change and human health. Moreover, we thematically map funding patterns according to four thematic areas: changes in climate, the effects of climate change, health impacts, and interventions and strategies. More funding is needed to better anticipate and prepare for the projected health impacts of climate change.
