Climate Change, Air, Water, and Planetary Systems

A section of Challenges (ISSN 2078-1547).

Section Information

This section of Challenges explores the profound impacts of human activity on Earth’s critical systems in the Anthropocene. As we exceed planetary boundaries—including climate stability, ocean acidification, freshwater use, biogeochemical flows, air quality, and stratospheric ozone depletion—this section investigates the cascading effects on ecosystems and the biosphere. By examining the interactions between climate change, air and water systems, ocean health, and broader planetary processes, we emphasize the urgent need for solutions that restore balance. Through research on pollution reduction, sustainable water management, climate resilience, biogeochemical cycling, and mitigating ozone depletion, this section seeks to advance understanding and actions to protect Earth’s interconnected systems. We publish regular research papers, viewpoints and reviews, and invite all authors to explain the relevance of their work to advancing more sustainable human development and planetary health.
