Texto completoMarine heatwaves (MHW) have increased in frequency and intensity since the last century. High atmospheric temperatures drive MHW and are often associated with an increase in coastal recreational activities, leading to the release of Organic Ultra Violet Filters (OUVF) present in sunscreens into bathing waters. Recently, adverse effects have been documented in marine organisms exposed to MHW and OUVF. However, little is known about the ecophysiological and behavioural responses to realistic exposures. The objective of this thesis was to study these responses on two key nearshore species with different ecological functions, the blue mussel (Mytilus edulis) and the golden grey mullet (Chelon auratus). This thesis demonstrated that (1) a realistic MHW caused metabolic or behavioural adjustments in both species, which in turn limited their ability to recover from the MHW and (2) that the behaviour of individuals exposed to environmental concentrations of OUVF increased the risk of bioaccumulating these pollutants in their tissues and induced adverse physiological effects (observed in C. auratus at the cellular and organ level). This work highlights the importance of considering the ability of individuals to cope with stress, by measuring their responses at several organizational levels in order to have a holistic view of the effects

Texto completoIntensifying climate change is increasingly affecting marine life in the world's oceans. Extreme events like marine heatwaves (MHWs), associated with climate change, are projected to grow in duration, intensity, and frequency, further impacting marine ecosystems throughout the 21st century. In this dissertation, I investigated the effects of climate change and MHWs on biomass flows in marine food webs and their consequences on ecosystem structure and functioning. I developed a dynamic version of the EcoTroph model, named EcoTroph-Dyn, which represents the functioning of marine ecosystems as a single flow of biomass from primary producers to top predators. To study MHW effects using EcoTroph-Dyn, I estimated MHW-induced mortality from 1982 to 2021 based on the thermal preferences of various taxa. The results reveal that MHWs may have impacted biomass flow through the perturbation of the kinetics of biomassflow and transfer efficiency and caused biomass loss through instantaneous mortality. Secondly, using EcoTroph-Dyn, I hindcasted consumer biomass in marine food webs from 1998 to 2021. By integrating changes in temperature and primary production, marine animal biomass was estimated at each trophic level on a 1° x 1° grid of the global ocean. Findings show significant biomass loss due to MHWs, with more pronounced impacts at higher trophic levels. Finally, projections from 1950 to 2100 indicate that MHW-induced changes in biomass flows could drive a global consumer biomass decline, surpassing the impacts of background climate change. Overall, this dissertation demonstrates that climate change and MHWs jointly disrupt biomass flows in marine ecosystems, leading to reduced future ocean animal biomass with direct repercussions on fisheries

Texto completoThe Mediterranean Sea is considered a "Hot Spot" region for future climate change and depending on the greenhouse emission scenario, the annual mean basin sea surface temperature (SST) is expected to increase from +1.5 °°C to +3 °°C at the end of the 21st century relative to present-day. This significant SST rise is likely to intensify episodes of extreme warm ocean temperatures in the basin, named as Marine heatwaves (MHWs), that are known to exert substantial pressure on marine ecosystems and related fisheries around the world. In this context, the main aim of this PhD work is to study the past variability and future evolution of MHWs in the Mediterranean Sea. We propose a detection method for long lasting and large-scale summer MHWs, using a local, climatological 99th percentile threshold, based on present-climate daily SST. MHW probability of occurrence and characteristics in terms of spatial variability and temporal evolution are then investigated, using additional integrated indicators (e.g. duration, intensity, spatial extension, severity) to describe past and future events. Within the PhD and depending on the applications, the detection method is applied to various datasets : In-situ observation at buoys, high-resolution satellite product, various high- resolution and fully-coupled Regional Climate System Models including the recently developed CNRM-RCSM6 and the multi-model (5), multi-scenario (3) Med-CORDEX ensemble. The detection method is first tested on the 2003 MHW in order to assess its sensitivity to various tuning parameters. We conclude that its characterization is partly sensitive to the algorithm setting. Hindcast and historical mode simulations show that models are able to capture well observed MHW characteristics. We then assess past surface MHW variability (1982-2017) and their underlying driving mechanisms using the CNRM-RCSM6 model. We examine their characteristics from surface to 55m depth, where most thermal stress-related mass mortalities of Mediterranean ecosystems have been observed in the past. The analysis indicates an increase in duration and intensity of surface events with time, while MHWs of 2003, 2012 and 2015 are identified as the most severe events of the period. In particular, an anomalous increase in shortwave radiation and a lower-than-normal vertical diffusion and latent heat loss appeared to be responsible for the development of the MHW 2003, with wind playing a key role in the intensity of temperature anomalies at the sea surface. Differences on the dominant forcing, however, are sometimes evident in the different subbasin.We finally use the Med-CORDEX RCSM ensemble to assess the future MHW evolution in the basin over 1976-2100. Our results suggest longer and more severe events with higher global-warming rates. By 2100 and under RCP8.5, simulations project at least one long- lasting MHW every year, up to 3 months longer, about 4 times more intense and 42 times more severe than present-day events. Their occurrence is expected between June-October affecting at peak the entire basin. Their evolution is found to mainly occur due to an increase in the mean SST but an increase in daily SST variability plays also a noticeable role. Up to mid-21st century MHW characteristics rise independently of the choice of the emission scenario, whose influence becomes more evident by the end of the period

Texto completoAn exceptional heat wave occurred during august 2003 in France, leading to more than 14,800 deaths estimated. We characterized all 'serious' adverse drug reactions (ADR) occurred in patients older than 70 years between 1st July and 31st August 2003, recorded in the French PharmacoVigilance Database, and related to excessive heat (n=68). The most frequently ADRs were metabolic. Drugs more frequently involved were diuretics, angiotensin converting enzyme inhibitors, and antidepressants. During another summer with a heat wave in 2006, diuretics were more frequently involved, whereas the number of ADRs was similar. In 2007, we performed a multicentric case-control study in 3 university hospitals in France, to compare drugs taken by patients hospitalized for a 'serious' hyperthermia and/or dehydratation with controls. Cases took more drugs than controls (4. 3 vs 3. 9; p<0. 001), particularly neuroleptic drugs (3. 6% vs 0. 5%; p=0. 007), and presented more severe renal impairment. This pilot work could allow improving methodology of further studies on drugs during heat waves

Texto completoExtreme temperature events largely impact socio-economic and environmental systems. Combining statistical analyses and modelling experiments in Europe, I show that in winter, global climate models simulate cold waves and associated climate variables. However, they overestimate their number by about 40%. A correct representation of snow cover and of the snow/atmosphere feedback reduces this bias in the models. In summer, they also simulate heat waves but tend to underestimate some linked physical mechanisms. Soil-moisture/atmosphere feedback explains the asymmetric predictability of heat waves: while high spring precipitation in Southern Europe contribute to their inhibition, in case of deficit, heat waves can develop or no. As soils become drier, this seasonal predictability is likely to be reduced in the future

Texto completoThis thesis deals with the study of the climate of West Africa using the global model developed at the Pierre Simon Laplace Institute and observations mainly acquired during the Multidisciplinary Analysis campaign of the African Monsoon AMMA. The work of the thesis aims more specifically at improving the representation of the West African climate by reducing the biases observed in the intercomparison exercise of coupled models CMIP5, in particular from atmosphere-surface interactions, with the aim of better predict the distribution of rainfall over the region but also extreme events such as heat waves. The results showed that the representation of seasonality of temperatures and rainfall in West Africa was altered by strong biases on the surface energy budget and large-scale circulation (latitudinal positioning of the key elements of the monsoon). The first part of the work consists of implementing an evaluation technique based on two experimental protocols and aimed at: i) distinguishing the biases due to the circulation of those due to the energy budget at the surface, ii) facilitating the exploitation of data on sites, iii) isolating the effect of parameterizations. In this section, the biases on circulation and water budget are illustrated. This study first demonstrates the great interest of the nudging method for the confrontation of a GCM with station data and for analyzing the effect of model parameterizations in West Africa. Then, The in-situ data are used to: 1) identify the biases on the energy budget, 2) link these biases to the defects of the parameterizations used in order to find ways to improve. With this study, a number of problems, such as a poor specification of bare soil albedo and different plant functional type or "bug" in the coupling between thermal inertia and soil moisture have been identified . Some are now corrected in recent versions of the model developed for the CMIP6 exercise. Also in this manuscript, we show the progress achieved through this methodology on the representation of the water and energy budget, as well as the remaining problems. Finally, one of the major aims of this study is the work on the role of aerosols in the representation of the West African climate and in the setting up of heat waves. In this part, we introduced a representation of dust interactive with meteorology and calculated its impact on the representation of the energy budget at the surface. Then, in the framework of the ANR ACASIS, we studied the heat wave of 2010. This work allowed us to highlight the link between aerosols and the increase of precipitable spring water and to demonstrate by this is the importance of aerosols in the representation of heat waves. Finally, we discussed the issue of dynamic-physical coupling using a new experimental protocol and through the analysis of the aerosols impact on monsoon rains
