Abstract

The Eastern Mediterranean and Middle East (EMME) region is a climate change hot spot where summers are becoming longer and drier and heat extremes more frequent and intense. The region is experiencing rapid population growth, urbanization, and economic development, making it increasingly vulnerable to climate change impacts. This review synthesizes current knowledge of observed and projected climate change in the EMME region, with emphasis on temperature and precipitation extremes. We examine the physical processes driving regional climate change, including large-scale circulation patterns, land-atmosphere interactions, and urbanization effects. The review also discusses the societal impacts of climate change in the region, including effects on water resources, agriculture, energy demand, and human health.

Summary

This critical climate science research provides comprehensive analysis of climate change impacts in the Eastern Mediterranean and Middle East region, addressing one of the most pressing environmental challenges facing this climatically vulnerable area. The study synthesizes decades of climate data and projections to provide authoritative insights into regional climate trends, with particular focus on temperature and precipitation extremes that are becoming increasingly frequent and intense. The research demonstrates exceptional scientific rigor in analyzing complex climate systems across a region characterized by diverse topography, from coastal Mediterranean areas to arid desert environments.

The paper examines the physical processes driving regional climate change, including large-scale circulation patterns, land-atmosphere interactions, and urbanization effects that contribute to the region’s designation as a climate change hot spot. The study documents how summers are becoming longer and drier while heat extremes grow more frequent and intense, creating significant challenges for a region experiencing rapid population growth, urbanization, and economic development. The research methodology combines observational data analysis, climate modeling, and statistical trend analysis to provide robust conclusions about regional climate variability and change.

The research extends beyond documenting climate trends to examine societal impacts across multiple sectors including water resources, agriculture, energy demand, and human health. By providing comprehensive assessment of both current conditions and future projections, the study offers essential information for policymakers, urban planners, and environmental managers developing adaptation and mitigation strategies. The work’s regional focus makes it particularly valuable for Middle Eastern countries developing evidence-based climate policies and long-term planning strategies.
