Background: Climate change poses a significant threat to global food and nutritional security, driven by increasing greenhouse-gas emissions and rising temperatures due to the greenhouse effect. Objective: This paper reviews the literature on climate change, focusing on its causes, projected impacts, and implications for agriculture, including physiological and metabolic plant activities, growth, productivity, pest infestation, and mitigation strategies. Key Aspects: 1. Causes of Climate Change: Greenhouse-gas emissions, particularly CO2, contribute to the greenhouse effect, resulting in rising global temperatures. 2. Projected Impacts: The average global temperature is projected to increase by [insert degree] Celsius, leading to substantial economic losses worldwide. Climate change affects crop respiration rate, evapotranspiration, pest infestation, weed flora, and crop duration. 3. Impact on Agriculture: Climate change influences physiological and metabolic activities of plants, leading to changes in growth and productivity. It also exacerbates pest infestation, affecting crop yield and quality. 4. Mitigation Strategies: Various mitigation strategies are discussed, including measures to reduce greenhouse-gas emissions, improve soil health, enhance crop resilience, and implement sustainable agricultural practices. Conclusion: Understanding the impacts of climate change on agriculture is crucial for developing effective mitigation and adaptation strategies. Addressing this challenge requires interdisciplinary efforts to promote sustainable agricultural practices and safeguard global food security
