Climate change biology is a field of research that investigates the impacts of anthropogenic climate change on biological systems across all levels of organization, from molecular to ecosystem scales. This interdisciplinary domain examines how changing climate variables, including temperature, precipitation, and extreme events, influence the physiology, behavior, evolution, distribution, and interactions of organisms, as well as the structure and function of populations, communities, and ecosystems. Its significance lies in understanding current and predicting future biological responses to climate change, informing conservation efforts, adaptation strategies, and policy development to mitigate biodiversity loss and maintain ecosystem services.
