“…In short, the decadal analysis of climate trends in Annaba city spanning from 2000 to 2029, including projections from 2024 to 2029, revealed significant shifts in temperature and precipitation patterns. The consistent warming trend observed, particularly in the last four years, aligns with global climate change patterns and presents challenges for various sectors including infrastructure planning, public health, and water resource management [16,55]. The fluctuations in precipitation levels and declining mean wind speeds underscore the need for adaptive measures to address the evolving climate dynamics in the region [56,57].…”

“…Moreover, the transition between seasons in the Mediterranean climate is marked by noticeable shifts in temperature and precipitation, with spring and autumn characterized by moderate temperatures and increasing rainfall as the region transitions from one extreme to another [31][32][33]. As part of the global climate change effects, urban areas within Mediterranean regions are facing challenges related to global warming, where built-up areas tend to retain heat and stagnant atmospheric conditions, resulting in higher temperatures compared to surrounding rural areas [16,34,35]. These effects are compounded by other factors such as reduced green spaces and increased energy consumption, contributing to heatwaves and elevated temperatures within Mediterranean cities [36,37].…”

“…This observation underscores the abnormal rhythm of climatic changes and provides a familiar framework for understanding and adapting to seasonal fluctuations in temperature and humidity. In contrast, the last decade (2020-2029) fully departed from the traditional seasonal variations experienced throughout the year, reflecting a notable shift in climatic seasonality characterized by two main seasons-moderate and challenging-and reflecting the evolving climatic conditions, emphasizing the need for adaptive design solutions that prioritize occupant comfort, energy efficiency, and environmental sustainability [16,59]. The prolonged duration of extreme climate conditions underscores the importance of implementing robust building performance standards and integrating renewable energy systems to enhance building resilience and reduce greenhouse gas emissions.…”

Global warming is one of the most pressing challenges of our time, contributing to climate change effects and with far-reaching implications for built environments. The main aim of this study is to assess the extent to which Annaba city, Algeria, as part of the Mediterranean region, is affected by global climate change and its broader influences. The study investigated climatic shifts in Annaba city, using a multi-step methodology integrating data collection and analysis techniques. Data collection included 23 years of climate data (2000–2023) from Annaba’s meteorological station, on-site measurements of microclimatic variations, and a questionnaire survey. The collected data underwent four main analyses: a time series analysis to describe climate parameters over 23 years, a statistical analysis to predict potential future climatic conditions (2024–2029) and the correlation of various climatic variables using specialized bioclimate tools to highlight seasonal variability, a spatial study of the urban heat island (UHI) phenomenon and perceived climatic shifts, and an analysis of extreme weather events characterizing heat atmospheric events in the context of urban climate change in the Mediterranean region. The findings revealed a consistent warming trend in Annaba city, with prolonged extreme climate conditions observed, particularly in the last four years (2020–2023). Significant temperature fluctuations were emphasized, notably in July 2023, with record-breaking maximum temperatures reaching 48.2 °C, the hottest on record with an increase of 3.8 °C, and presenting challenges amplified by the urban heat island effect, causing temperature differentials of up to 6 °C within built-up areas. Projections for 2029 suggest a tendency towards heightened aridity with a significant shift towards a new climate seasonality featuring two distinct main seasons—moderate and hot challenging. The abrupt disruption of calm weather conditions in Annaba on 24 July 2023 highlighted the influence of atmospheric circulation within the Mediterranean region featured for both anticyclones and atmospheric blocking phenomena on local weather patterns.

“…Climate change is producing high global warming in a short period of time, causing health, the economy and the environment to be negatively affected, such as the heat waves present in large cities [1][2][3]. This situation especially affects the Mediterranean area, whose temperatures exceed the global average by 1.4 • C [4]. Therefore, it is necessary for buildings to mitigate these effects and respond to future needs [4,5].…”

Within a context in which temperatures are increasing due to global warming, it is important to assess the capacity of buildings, old and modern, to respond to this new situation. Recent studies have highlighted the importance of understanding more about the thermal properties of traditional constructions. This study quantifies the impact of the high summer temperatures typical of the Mediterranean climate on traditional farmhouses in Eastern Almería (Spain). The study group of farmhouses was divided into three models representative of the different types of Eastern Almería vernacular architecture. Energy consumption in the three models was simulated using EnergyPlus. The three models were assessed in free-floating conditions. The window-to-wall ratio and U-factor values were studied in order to evaluate potential benefits in terms of energy efficiency. Outdoor and indoor temperatures were compared. Finally, an adaptive thermal comfort analysis was performed according to ASHRAE 55. Results highlight the ability of Eastern Almería farmhouses to mitigate extreme temperatures.

The Mediterranean region contains some of the areas with the highest urban density in the world, and these areas keep expanding, making this region a “hotspot” of climate change. Life in the Mediterranean unfolds predominantly outdoors throughout the year, exposing its inhabitants to an evolving climate that is progressively harsher and punctuated by increasingly frequent extreme weather events. More and more people are going to be exposed to severe heat waves, droughts, water shortage, dust storms, forest fires and poor air quality on the one hand, and torrential rains and floods on the other hand. The urban heat island further increases thermal stress of city dwellers and plays a key role in citizens' health and well‐being. In this exhaustive review, based on state‐of‐the‐art studies we delve into the realm of climate change and extreme weather phenomena as they intersect with urban populations in Mediterranean cities, both in the present and in the foreseeable future. Our focus lies on identifying knowledge gaps, inconsistencies in observed climatic hazards and shortcomings in assessing the associated risks and their societal and environmental ramifications. Moreover, we undertake a comprehensive survey of future predictions exploring the variables thermal stress, air pollution, air quality and characteristics of the hydro‐climatic systems, that is, droughts, fires and floods. Yet, critical knowledge gaps persist in understanding the science, the coping mechanisms, the strategies for preparedness and adaptation and the intricate interplay between these facets and societal dynamics. The developing countries in the Mediterranean region stand exceptionally vulnerable. It is imperative for more affluent nations to share their expertise and extend assistance to less developed counterparts, aiding them in navigating climate‐related challenges, devising adaptive strategies and facilitating their implementation.
