As interdisciplinary research attracts more attention, interdisciplinarity has become a significant factor to be explored for scientific impact. This study explored the influence of interdisciplinarity on scientific impact in the field of climate change, based on Web of Science data. Taking newly‐developed indicator DIV* and its components as interdisciplinarity measures, we used OLS regression and topic analysis to analyze their relationships with short‐term and long‐term scientific impact, respectively. We found that DIV* had an inverted U‐shaped relationship with scientific impact in overall positive correlation, and both long‐ and short‐term scientific impact increased with the growth of interdisciplinarity with a declining growth rate in most cases. For the three components of DIV*, balance and disparity are negatively and positively correlated with scientific impact, respectively, while variety has an inverted U‐shaped relationship. These findings provided theoretical and decision‐making support for evaluating the impact of interdisciplinary research in the field of climate change.
