“…This strong role of convective precipitation that gives place to heavy rainfalls and flash floods can be explained by the orography surrounding the Mediterranean Sea, the high frequency of surface lows (Romero et al, 1999;Jansà et al, 2014) and the strong potential instability in low levels favored by a warm sea. Pastor et al (2020) have found a continuous warming trend of 0,035ºC/y of SST for the entire Mediterranean, that means an accumulated change of 1,3ºC between 1982 and 2019, while Cramer et al (2018) have observed an increase of 1ºC for the entire Mediterranean Region and the same period. This differential trend between SST and air temperature near surface would be indicating a worsening of the thermodynamic conditions favorable to convection.…”

“…The temperature of the Mediterranean Sea has increased by about 0.4ºC/decade between 1985 and 2006, increasing more in the East (about 0.5ºC/decade) than in the West (about 0.3ºC/decade). Recently, Pastor et al (2020) have showed that Sea Surface Temperature (SST) of the Mediterranean has increase 1.3ºC between 1982 and 2019. This warming is greatest in May, June and July.…”

Floods are the most important risk in the Mediterranean region, both due to their frequency and impact. Studies of historical floods show flood-rich periods that could be associated with climate causes, but there is also a certain growing trend as a result of changes in land use and increased vulnerability. If climate scenarios point to an increase in the torrentiality of precipitation, with longer dry periods and more intense rainfall, there is still a high level of uncertainty in their impact in floods. This paper addresses this issue, also considering the complex role of changes to hazards, vulnerability, exposure and capacity. It presents a synthesis of the state of the art, with particular incidence in the first results of MedECC and the most recent bibliography on floods trend. Conclusions show that floods in this region are mainly consequence of flash-flood events. A common positive trend of flash floods in the past probably due to land use changes and the occupation of flood-prone areas has been found (high confidence). The increase of convective precipitation could also justify this positive trend in the most recent period, in some regions (low confidence). Vulnerabilities to water related hazards are expected to be influenced by the future socio-economic conditions at the regional scale (medium confidence). Although expected changes in flood risks are not univocal, nor evenly distributed, flood impacts will increase in the entire Mediterranean region, mainly as a consequence of global changes in the catchments (land use, vulnerability, exposure), joined in the Northern part of the basin to the increase of heavy rainfalls (medium confidence).

“…Resulta muy destacable que desde el año 2000 se han observado registros de 29-30ºC en el ecuador del verano en las aguas próximas a las Islas Baleares y Argelia. Esto último repercute sobre el clima de esta región: un mar más cálido favorece el incremento de las noches tropicales en la costa (Pastor et al, 2020). Esto se debe a que la temperatura del aire no puede descender al encontrarse una masa de agua tan cálida frente al litoral, mientras que por el día las brisas pueden contribuir a incrementar la sensación de bochorno, concretamente en días en que la temperatura del Mediterráneo alcanza o supera los 28ºC en la costa, porque el mar transmite el calor y la humedad al aire situado por encima de él.…”

“…Al respecto, hay autores que señalan que esta área se ha convertido en una región-riesgo destacada a nivel mundial (Calvo, 2001). En materia climática, el litoral mediterráneo español registra ya los efectos del calentamiento térmico planetario, con manifestaciones regionales: el clima se ha vuelto menos confortable térmicamente, con extremos térmicos y regularidad de calor nocturno -incremento notable de "noches tropicales"-y más irregular en el desarrollo de eventos extremos de precipitación y viento -temporales marítimos- (Pastor, Valiente y Khodayar, 2020).…”

La educación es una acción fundamental para reducir la acción de los riesgos naturales dentro del contexto del cambio climático actual. No obstante, en los países desarrollados no ha tenido un protagonismo destacado en cuanto al diseño de las políticas de prevención de estos riesgos. Y ello, a pesar del papel que cubre en la concienciación que puedan lograr las cohortes más jóvenes de la sociedad ya que serán protagonistas de estos procesos en las próximas décadas. Este trabajo tiene por objeto proponer actividades didácticas para el tratamiento de cinco procesos principales de manifestación extrema del clima que ya afectan a la región mediterránea y que deben incorporarse en la asignatura de Geografía (Educación Secundaria y Bachillerato). Estas propuestas pretenden ser una guía de trabajo en el aula para ser implementadas en otros territorios, teniendo en cuenta sus rasgos geográficos y disponibilidad de datos. Su implementación en el aula y las ediciones futuras de los libros de texto suponen una apuesta por el factor educación como recurso básico para conseguir una sociedad más resiliente a los extremos atmosféricos vinculados al proceso de cambio climático.

Recurrent marine heatwaves threaten the resilience and viability of a key Mediterranean octocoral species

Long‐term ecological studies are essential for understanding the resilience of temperate reefs to ocean warming and the response of their habitat‐forming species to recurrent marine heatwaves (MHWs). This study evaluated the long‐term response (2005–2021) of the habitat‐forming octocoral Eunicella singularis (Esper, 1791) to recurrent MHWs in a Mediterranean marine protected area established more than 25 years ago, where restrictions on fishing and diving activities are well enforced. During the study period, there were two mass‐mortality events (MMEs), in 2007 and 2018, that dramatically disrupted the local gorgonian population. The MMEs were triggered by different temperature dynamics, which ultimately led to differential patterns in mortality rates. The record‐breaking MHW in 2018 prompted one of the largest MMEs ever recorded in the Mediterranean Sea, which affected 75% of the individuals in the gorgonian population and killed 12.5% of colonies. Furthermore, MHWs were detected in all years from 2014 to 2021, preventing injured tissues from fully recovering, leading to significant accumulated damage at the end of the study period (30 times higher than the levels prior to the first MME), and a marked decrease in resilience that threatens the population viability of this long‐lived species. The octocoral studied is one of the most important structural and biomass contributors to one of the most diverse Mediterranean communities. These results underscore the great risk that annual MHWs pose to the long‐term integrity of the circalittoral rocky bottoms of the Mediterranean coasts. In the face of climate change, MPAs must provide areas of reduced anthropic stress for gorgonian populations, enabling the restoration and maintenance of natural processes. Additionally, MPAs should serve as sentinel areas to test the effectiveness of coral restoration actions, which can help managers and scientists to estimate the usefulness of these techniques.
