This review critically examines the effects of elevated carbon dioxide (CO2) levels and temperature on nutrient properties in various ecosystems. With rising atmospheric CO2 concentrations and global temperatures, understanding how these environmental changes influence nutrient dynamics is crucial for predicting their impact on ecosystem functioning and productivity. Elevated CO2 levels can affect nutrient availability, uptake, and allocation in plants, leading to alterations in nutrient cycling and ecosystem processes. Similarly, increasing temperatures can influence nutrient mineralization rates, microbial activity, and soil nutrient availability, further shaping ecosystem nutrient dynamics. By synthesizing current literature and research findings, this review provides insights into the complex interactions between elevated CO2, temperature, and nutrient properties, highlighting the importance of considering multiple factors in assessing ecosystem responses to climate change.
