A Review of Physics in Climate Studies

Abstract

Climate studies are fundamentally rooted in physical principles governing the Earth’s atmosphere, oceans, cryosphere, and land systems. Physics provides the theoretical framework to understand energy balance, fluid dynamics, radiation transfer, thermodynamics, and phase transitions that collectively drive climate variability and change. This review presents a comprehensive examination of the role of physics in climate science, focusing on atmospheric dynamics, radiative forcing, ocean circulation, cloud physics, and feedback mechanisms. A comparative analysis of physical climate processes highlights their relative influence on climate sensitivity and predictability. The review further discusses modeling challenges, observational constraints, and future research directions, emphasizing the indispensable role of physics in understanding and addressing climate change.
