Climate change is considered one of the most significant challenges facing the field of Civil Engineering in the modern era due to its direct impact on the safety of structures, infrastructure, and the efficiency of engineering projects. The role of the civil engineer is no longer limited to designing and constructing facilities only; rather, it has become closely associated with achieving sustainability and the ability to cope with changing environmental conditions. With the increasing temperatures and the rising frequency of floods, storms, and heavy rainfall, concrete structures, bridges, roads, and infrastructure networks have become more vulnerable to damage and deterioration. High temperatures cause the expansion of construction materials such as concrete and steel, leading to cracks and weakening of structural elements over time. Sudden temperature fluctuations also result in rapid expansion and contraction of materials, negatively affecting the lifespan and stability of structures. Furthermore, floods and rising water levels are among the most dangerous factors affecting civil engineering works, as they directly impact foundations, cause soil erosion and deterioration of construction materials, and may lead to partial or total collapse of buildings, bridges, and roads, especially in areas with weak drainage systems. Heavy rainfall and flash floods also cause severe damage to road networks and infrastructure, in addition to soil settlement and cracking beneath foundations, which affects the stability of engineering structures in general. Strong winds and storms impose additional loads on buildings and structures, requiring civil engineers to adopt modern design standards that consider resistance to harsh climatic conditions and ensure the safety and continuity of structures. The impacts of climate change are not limited to structural aspects only, but also extend to operational aspects, as the demand for cooling systems and energy increases due to rising temperatures, resulting in higher energy consumption, pressure on electrical grids, and reduced efficiency of various operational systems. Consequently, the role of Civil Engineering has emerged in providing sustainable solutions through designing resilient structures capable of adapting to climate change, using environmentally friendly construction materials, developing modern drainage systems, and relying on renewable energy and green building technologies. These efforts are directly linked to the Sustainable Development Goals adopted by the United Nations, which aim to achieve a safer and more sustainable future for humanity. Goal 9 focuses on building resilient and sustainable infrastructure and promoting industrial innovation, while Goal 11 calls for creating sustainable cities and communities capable of facing disasters and environmental changes. Goal 13 emphasizes taking urgent action to combat climate change and strengthen resilience to its risks, in addition to Goal 7, which encourages the use of clean energy and improving energy efficiency. The United Nations Sustainable Development Goals confirm that the SDGs represent a global plan to protect the planet and ensure prosperity for all. The United Nations Sustainable Development Platform also indicates that climate action and sustainable infrastructure are among the essential pillars for achieving sustainable development by 2030, while Goal 9: Industry, Innovation, and Infrastructure highlights the importance of establishing strong and resilient infrastructure capable of supporting economic and social development and confronting the impacts of climate change. Therefore, Civil Engineering today represents the first line of defense against the challenges of climate change through the development of sustainable engineering designs that contribute to protecting structures and achieving a safer and more sustainable urban environment for future generations.
