The epic battle for control of the Strait of Gibraltar waged by Castile, Morocco, and Granada in the late thirteenth and early fourteenth centuries is a major, but often overlooked, chapter in the history of the Christian reconquest of Spain. After the Castilian conquest of Seville in 1248 and the submission of the Muslim kingdom of Granada as a vassal state, the Moors no longer loomed as a threat and the reconquest seemed to be over. Still, in the following century, the Castilian kings, prompted by ideology and strategy, attempted to dominate the Strait. As self-proclaimed heirs of the Visigoths, they aspired not only to reconstitute the Visigothic kingdom by expelling the Muslims from Spain but also to conquer Morocco as part of the Visigothic legacy. As successive bands of Muslims over the centuries had crossed the Strait from Morocco into Spain, the kings of Castile recognized the strategic importance of securing Algeciras, Gibraltar, and Tarifa, the ports long used by the invaders.At a time when European enthusiasm for the crusade to the Holy Land was on the wane, the Christian struggle for the Strait received the character of a crusade as papal bulls conferred the crusading indulgence as well as ancillary benefits. The Gibraltar Crusade had mixed results. Although the Castilians seized Gibraltar in 1309 and Algeciras in 1344, the Moors eventually repossessed them. Only Tarifa, captured in 1292, remained in Castilian hands. Nevertheless, the power of the Marinid dynasty of Morocco was broken at the battle of Salado in 1340, and for the remainder of the Middle Ages Spain was relieved of the threat of Moroccan invasion. While the reconquest remained dormant during the late fourteenth and early fifteenth centuries, Ferdinand and Isabella conquered Granada, the last Muslim outpost in Spain, in 1492. In subsequent years Castile fulfilled its earlier aspirations by establishing a foothold in Morocco.

Twenty-first century projections for the Mediterranean water properties have been analyzed using the largest ensemble of regional climate models (RCMs) available up to now, the Med-CORDEX ensemble. It is comprised by 25 simulations, 10 historical and 15 scenario projections, from which 11 are ocean–atmosphere coupled runs and 4 are ocean forced simulations. Three different emissions scenarios are considered: RCP8.5, RCP4.5 and RCP2.6. All the simulations agree in projecting a warming across the entire Mediterranean basin by the end of the century as a result of the decrease of heat losses to the atmosphere through the sea surface and an increase in the net heat input through the Strait of Gibraltar. The warming will affect the whole water column with higher anomalies in the upper layer. The temperature change projected by the end of the century ranges between 0.81 and 3.71 °C in the upper layer (0–150 m), between 0.82 and 2.97 °C in the intermediate layer (150–600 m) and between 0.15 and 0.18 °C in the deep layer (600 m—bottom). The intensity of the warming is strongly dependent on the choice of emission scenario and, in second order, on the choice of Global Circulation Model (GCM) used to force the RCM. On the other hand, the local structures reproduced by each simulation are mainly determined by the regional model and not by the scenario or the global model. The salinity also increases in all the simulation due to the increase of the freshwater deficit (i.e. the excess of evaporation over precipitation and river runoff) and the related increase in the net salt transport at the Gibraltar Strait. However, in the upper layer this process can be damped or enhanced depending upon the characteristics of the inflowing waters from the Atlantic. This, in turn, depends on the evolution of salinity in the Northeast Atlantic projected by the GCM. Thus a clear zonal gradient is found in most simulations with large positive salinity anomalies in the eastern basin and a freshening of the upper layer of the western basin in most simulations. The salinity changes projected for the whole basin range between 0 and 0.34 psu in the upper layer, between 0.08 and 0.37 psu in the intermediate layer and between − 0.05 and 0.33 in the deep layer. These changes in the temperature and salinity modify in turn the characteristics of the main water masses as the new waters become saltier, warmer and less dense along the twenty-first century. There is a model consensus that the intensity of the deep water formation in the Gulf of Lions is expected to decrease in the future. The rate of decrease remains however very uncertain depending on the scenario and model chosen. At the contrary, there is no model consensus concerning the change in the intensity of the deep water formation in the Adriatic Sea and in the Aegean Sea, although most models also point to a reduction.

The Forbes’ Quarry and Devil’s Tower partial crania from Gibraltar are among the first Neanderthal remains ever found. Here, we show that small amounts of ancient DNA are preserved in the petrous bones of the 2 individuals despite unfavorable climatic conditions. However, the endogenous Neanderthal DNA is present among an overwhelming excess of recent human DNA. Using improved DNA library construction methods that enrich for DNA fragments carrying deaminated cytosine residues, we were able to sequence 70 and 0.4 megabase pairs (Mbp) nuclear DNA of the Forbes’ Quarry and Devil’s Tower specimens, respectively, as well as large parts of the mitochondrial genome of the Forbes’ Quarry individual. We confirm that the Forbes’ Quarry individual was a female and the Devil’s Tower individual a male. We also show that the Forbes’ Quarry individual is genetically more similar to the ∼120,000-y-old Neanderthals from Scladina Cave in Belgium (Scladina I-4A) and Hohlenstein-Stadel Cave in Germany, as well as to a ∼60,000- to 70,000-y-old Neanderthal from Russia (Mezmaiskaya 1), than to a ∼49,000-y-old Neanderthal from El Sidrón (El Sidrón 1253) in northern Spain and other younger Neanderthals from Europe and western Asia. This suggests that the Forbes’ Quarry fossil predates the latter Neanderthals. The preservation of archaic human DNA in the warm coastal climate of Gibraltar, close to the shores of Africa, raises hopes for the future recovery of archaic human DNA from regions in which climatic conditions are less than optimal for DNA preservation.

Spring 1937. In the four years since she left England, Maisie Dobbs has experienced love, contentment, stability -- and the deepest tragedy a woman can endure. Now, all she wants is the peace she believes she might find by returning to India. But her sojourn in the hills of Darjeeling is cut short when her stepmother summons her home to England; her aging father Frankie Dobbs is not getting any younger. But on a ship bound for England, Maisie realizes she isn't ready to return. Against the wishes of the captain who warns her, \"You will be alone in a most dangerous place,\" she disembarks in Gibraltar. Though she is on her own, Maisie is far from alone: the British garrison town is teeming with refugees fleeing a brutal civil war across the border in Spain. Yet the danger is very real. Days after Maisie's arrival, a photographer and member of Gibraltar's Sephardic Jewish community, Sebastian Babayoff, is murdered, and Maisie becomes entangled in the case, drawing the attention of the British Secret Service. Under the suspicious eye of a British agent, Maisie is pulled deeper into political intrigue on \"the Rock\" -- arguably Britain's most important strategic territory -- and renews an uneasy acquaintance in the process. At a crossroads between her past and her future, Maisie must choose a direction, knowing that England is, for her, an equally dangerous place, but in quite a different way.

The principal argument in Gibraltar and Empire is that Gibraltarians constitute a separate and distinctive people, notwithstanding the political stance taken by the government of Spain. Various factors - environmental, ethnic, economic, political, religious, linguistic, educational and informal - are adduced to explain the emergence of a sense of community on the Rock and an attachment to the United Kingdom. A secondary argument is that the British empire has left its mark in Gibraltar in various forms - such as militarily - and for a number of reasons. Gilbraltar and Empire's exploration of the manifold reasons why the Gibraltarians have bucked the trend in the history of decolonization comes at a time when the issues in question have come to the fore in diplomatic and political areas.

Estimating long-term modifications of the sea surface temperature (SST) is crucial for evaluating the current state of the oceans and to correctly assess the impact of climate change at regional scales. In this work, we analyze SST variations within the Mediterranean Sea and the adjacent Northeastern Atlantic box (west of the Strait of Gibraltar) over the last 37 years, by using a satellite-based dataset from the Copernicus Marine Environment Monitoring Service (CMEMS). We found a mean warming trend of 0.041 ± 0.006 ∘ C/year over the whole Mediterranean Sea from 1982 to 2018. The trend has an uneven spatial pattern, with values increasing from 0.036 ± 0.006 ∘ C/year in the western basin to 0.048 ± 0.006 ∘ C/year in the Levantine–Aegean basin. The Northeastern Atlantic box and the Mediterranean show a similar trend until the late 1990s. Afterwards, the Mediterranean SST continues to increase, whereas the Northeastern Atlantic box shows no significant trend, until ~2015. The observed change in the Mediterranean Sea affects not only the mean trend but also the amplitude of the Mediterranean seasonal signal, with consistent relative increase and decrease of summer and winter mean values, respectively, over the period considered. The analysis of SST changes occurred during the “satellite era” is further complemented by reconstructions also based on direct in situ SST measurements, i.e., the Extended Reconstructed SST (ERSST) and the Hadley Centre Sea Ice and Sea Surface Temperature dataset (HadISST), which go back to the 19th century. The analysis of these longer time series, covering the last 165 years, indicates that the increasing Mediterranean trend, observed during the CMEMS operational period, is consistent with the Atlantic Multidecadal Oscillation (AMO), as it closely follows the last increasing period of AMO. This coincidence occurs at least until 2007, when the apparent onset of the decreasing phase of AMO is not seen in the Mediterranean SST evolution.
