Special Issue Information

Dear Colleagues,

Recent observations and modelling highlighted the Eastern Mediterranean (EM) as an important climate change hotspot. Over the last few decades, the EM’s atmosphere has been warming at a rate almost double the global average, while greenhouse gas emissions in the EM and Middle East regions are also growing at high rates. Seawater temperature is increasing rapidly and “marine heatwaves” have been frequently observed over the last few years, thus facilitating the migration of invasive species. Recently, the IPCC highlighted that extreme weather events including wildfires, floods, drought frequency and severity, as well as aridity, agricultural and hydrological droughts, desertification, and sea-level rise will increase in the coming years. These events will significantly affect infrastructures, human activities, and the economy in a wide range of sectors, including agriculture, forestry, health, ecosystem functioning, displacements, and migration.

The Special Issue entitled “The Drivers and Impacts of climate change over the Eastern Mediterranean” aims to provide an updated overview of the drivers affecting climate change in the region and highlight the impacts of climate change on various societal sectors, as well as the need for tool development for early warning systems. Although it will be largely based on results obtained during the implementation of the CLIMPACT initiative, additional contributions are also welcome.

Appropriately designed and implemented climate mitigation actions have multiple co-benefits (yet some trade-offs cannot be excluded) that result in substantial social and economic value beyond their direct impact on reducing energy consumption and GHG emissions. Despite their wider acknowledgement by the research community, decision makers and the public have incomplete information on these multiple effects. This paper has a twofold objective: First, through analytical bottom-up approaches, it assesses, in quantitative terms, the macroeconomic effects and the public health benefits attributed to a variety of mitigation actions under consideration in the context of the Greek Energy and Climate Plan. Second, it investigates, through a social survey, how citizens perceive climate change and value these multiple impacts of mitigation actions, and to what extent they are willing to pay for them and support the adoption of policy measures aiming at the green transition of the Greek economy. We show that mitigation actions bring about significant health benefits, particularly in cities, and generate significant positive macroeconomic effects, particularly if mitigation actions focus on the decarbonization of the building sector and on the exploitation of local renewable sources. We also argue that most people do not realize that climate mitigation actions can have wider benefits for society, such as tackling energy poverty, improving public health, and creating new jobs. Unwillingness to pay tends to be the prominent attitude. People who are more reluctant to cover a part of the cost of environmental protection are less likely to perceive that climate change is one of the main challenges at global and national level and support the adoption of climate mitigation policies. In this context, the national strategy for climate change should focus on effectively informing and engaging the public in climate mitigation strategies, strengthening the public trust in government institutions, promoting mutually acceptable solutions with the local communities, and providing incentives for changing citizens’ behavior towards climate-related actions.

Climate change is expected to significantly affect countries in Southern Europe and the Mediterranean Basin, causing higher-than-average temperature increases, considerable reductions in rainfall and water runoff, and extreme events such as heatwaves. These pose severe threats to local energy systems, requiring a reliable and quantitative risk analysis. A methodological approach is thus proposed which covers both energy supply and demand, utilizing the latest climate projections under different greenhouse gas emissions scenarios and an appropriate scale for each energy form. For energy supply technologies, risks are assessed through statistical regression models and/or mathematical equations correlating climatic parameters with energy productivity. To analyze climate risks for energy demand, bottom–up models were developed, integrating both behavioral and policy aspects which are often considered in a very limited way. The results show that climate change will mainly affect electricity generation from hydroelectric and thermal power plants, with variations depending on the plants’ locations and uncertainties associated with precipitation and runoff changes. The climate risks for solar and wind energy were found to be low. Energy consumption will also be affected, but the range of risks depends on the ambition and the effectiveness of measures for upgrading the thermal performance of buildings and the intensity of climate change.
