Genome editing, mainly through CRISPR-Cas9 technology, presents a transformative approach to develop climate-adaptive crops. As climate change poses unprecedented challenges to agriculture, such as extreme weather events, pests, and diseases, there is an urgent need to enhance crop resilience and productivity. This review examines the potential of genome editing to introduce desirable traits into crops, including drought tolerance, heat resistance, and improved nutrient use efficiency. We explore recent advancements in genome editing technologies, their application in major crops, and the ethical and regulatory considerations surrounding their use. By leveraging genome editing, we can accelerate the development of crops capable of thriving in changing climates, ensuring food security and sustainable agriculture.
