Abstract

Climate variability significantly influences public health, shaping disease patterns, mortality rates, and the resilience of healthcare systems. This study presents a bibliometric analysis of global research on the relationship between climate variability and public health from 2000 to 2024. Drawing data from the Web of Science and PubMed, 4,746 publications were analysed using RStudio to identify research trends, influential works, leading contributors, and thematic developments in the field. Key bibliometric techniques such as citation analysis, co-authorship mapping, keyword co-occurrence, and thematic evolution analysis were employed to uncover the intellectual structure and trajectory of this domain. The findings reveal a notable surge in climate-health research over the past five years, reflecting increased interdisciplinary collaboration across environmental science, epidemiology, and health policy. While publication output remained modest in the early 2010s, foundational work during that period contributed to the field's exponential growth in recent years. Citation metrics highlighted the most impactful studies and journals, while country-level analysis illustrated evolving global contributions. Keyword analysis identified shifting research priorities, with growing attention to adaptation, resilience, and policy integration. Patterns in authorship and institutional affiliations underscored the expanding and international nature of climate-health research. This study offers valuable insights and a forward-looking perspective to guide evidence-based strategies for addressing climate-driven health challenges.
