Climate change is becoming a pressing reality in the Middle East and North Africa (MENA), a region already among the hottest and driest on Earth. Some areas regularly experience summer temperatures above 50 °C, which pose serious risks to public health, strain water resources, and increase the need for energy to cool homes and buildings. The region is on track to exceed critical global warming thresholds of 1.5 °C and 2 °C above pre-industrial levels much sooner than other parts of the world. Recent climate models, using high-resolution data from CMIP5 and CMIP6, show that warming in the region is not uniform. For instance, the interior of the Arabian Peninsula is warming up to 3.5 times faster than the global average. At this rate, the region could face warming of 3 to 4 °C as early as the 2070s, decades before other regions. The most affected areas include Riyadh province in Saudi Arabia, parts of Algeria and Mauritania, and the Elbourz Mountains in Iran during winter. By 2100, the most extreme climate scenarios predict warming of up to 9 °C in the central Arabian Peninsula, an area already arid and poorly equipped to handle such conditions. This warming is worsened by the region's desert landscape, which lacks the natural ability to cool through evaporation. The consequences of these changes are far-reaching. In a scenario of intense warming, certain parts of the region could become uninhabitable for humans. Heatwaves will become more frequent, longer, and more severe, increasing the risk of dehydration, heat exhaustion, and other heat-related illnesses. Ecosystems will also suffer, with agricultural lands—already limited—becoming even less productive, worsening food insecurity. Access to water, already scarce, will become even more limited, leading to tensions over natural resources and potentially causing mass migrations to areas less affected by warming. Urban infrastructure in densely populated coastal cities like those in Oman or the Gulf is not designed to withstand such extreme temperatures. Researchers suggest that ambitious global efforts to reduce greenhouse gas emissions could slow the warming rate in the region by up to 38 percent. This will require serious commitments from both major economies and countries in the region, many of which are rich in fossil fuels. Adaptation will also be crucial. Cities in the MENA region could become testing grounds for innovative solutions to combat extreme heat, such as better-ventilated buildings, light-reflecting materials, and urban greening. Though challenging in arid regions, these initiatives could reduce the need for air conditioning and serve as models for other areas facing similar challenges. The rise in temperatures in the MENA region has broader implications beyond the environment and economy, fueling social and geopolitical tensions. Increasing food insecurity and water scarcity amplify inequalities between rural and urban communities, raising the risk of internal conflicts. On an international scale, these challenges may lead to significant waves of migration, with millions seeking refuge in areas less affected by warming. These mass displacements could destabilize existing geopolitical balances, highlighting the need for international cooperation to prevent future humanitarian crises. As the region faces more frequent heatwaves and water scarcity, countries must rethink their energy and economic models. The paradox lies in their heavy reliance on fossil fuels, both as a primary revenue source and a contributor to climate change. While some countries, such as the United Arab Emirates and Saudi Arabia, are investing in renewable energy, particularly solar and green hydrogen, the transition remains slow and uneven. The increase in temperatures also drives up electricity demand for cooling, straining energy infrastructure and increasing the use of polluting energy sources. Economic diversification and strong environmental policies will be essential to ensure the region's resilience against future climate challenges.
