Der volle Inhalt der QuelleENSO is the dominant mode of climate variability in the Pacific, having widespread socio-economical impacts. ENSO characteristics have been observed to exhibit substantial irregular variability from decadal to millennial timescales. The origin of such richness in ENSO variability timescales is likely due to the combined effects of timescales interaction processes within the tropical Pacific (through self-sustained nonlinear dynamics) and to external forcing (e. G. Volcanic activity, changes in greenhouse gases. . . ). In this thesis, we propose a new statistical framework that allows documenting high statistical moments in observed and simulated timeseries and that provides a robust estimation of nonlinearity in the tropical coupled system. As a first step, from the analysis of long-term CGCM simulations and extended reconstructed SST data sets, it is demonstrated that an interaction between interdecadal mean state changes in the tropical Pacific and extreme El Niño events probability occurs. This supports the hypothesis of ENSO variability being rectified at a wide range of frequencies by the slowly varying mean state through nonlinear processes phase-locked to the seasonal cycle alternatively in the Western and Eastern tropical Pacific. We then question to which extent the increase in greenhouse gases can alter the ENSO properties with a focus on its nonlinear character. Taking advantage of the IPCC database and different projections scenarios, nonlinearities are diagnosed in a model ensemble; and a relevant metric of the change in nonlinearity due to climate change is defined. This new metric allows highlighting a zonal see-saw in nonlinearity patterns associated with the change in El Niño characteristics observed in recent years. The traditional 20th century El Niño fingerprint, localized in the Cold Tongue, is robustly displaced westward in a warmer climate leading to El Niño Modoki-type patterns. We relate this switch in El Niño types to a change in nonlinearity pattern from present-day climate to a warmer climate. Secondly, we focused on the eastern tropical Pacific and the Humboldt Current System modelling and especially on the ability of Galapagos Islands and intra-seasonal activity in rectifying their mean state. Unlike recent studies, we put into perspective the role of this archipelago in altering this regional mean state. On the other hand, the intra seasonal Kelvin waves activity has the potential to revitalize the local mean circulation, the vertical stratification and therefore the Eastern Pacific dynamics, which in turn may have the potential to affect ENSO through upscaling effects

Der volle Inhalt der QuelleTransition risk, inherent in the shift to a low-carbon economy, presents significant challenges and opportunities for financial markets. This thesis aims to quantify and analyze the influence of this risk on stock returns, taking into account regulatory, technological, and consumer and investor preference developments. Taking part initially in the debate on the most appropriate measure to approximate a company’s contribution to transition risk, in Chapter 1, we propose the use of verified carbon emissions to assess the impact of transition risk on companies participating in the EU ETS. Our results show that the emissions trading system alters the risk-return profile of stocks, which can provide a financial incentive to consider emissions in investment decisions. Next, recognizing the pivotal role of central banks in the transition to a low-carbon economy, Chapter 2 provides an evaluation of the environmental footprint of U.S. monetary policy concerning transition risk. The main conclusion of non-neutrality in U.S. monetary policy, favoring polluting companies, leads to the third chapter. This chapter, also focused on the United States, explores how transition risk is taken into account in market valuation and how climate regulation can influence this integration. Our results suggest that the long-term impact of U.S. laws on the relationship between carbon emissions and stock returns needs strengthening to ensure its sustainability. Currently, legislative measures have a more pronounced effect in the medium term, but their sustainability remains uncertain. In conclusion, these chapters aim to enable a better integration of transition risk into stock evaluation by investors, which would empower regulatory authorities and financial market participants to develop more suitable policies and preventive measures against this risk

Der volle Inhalt der QuelleThe phasing between increases in temperature and greenhouse gas concentrations during large climatic variations in the past is classically estimated using analyses in polar ice cores, in the ice phase for the temperature and in the gas phase (trapped air bubbles) for the concentration of greenhouse gases. This phasing is still insufficiently constrained and solving this problem requires a better understanding of the mechanical process of snow to ice metamorphism near to the top of the ice sheet (i.e. the firn, about 100 m deep). In the absence of melting, the transformation of snow (a material with open porosity in contact with the atmosphere) into ice (a material containing isolated bubbles) occurs progressively as a response to temperature gradients near the surface, and the weight of overlying snow in deeper layers. Depending on temperature and precipitation conditions, this process occurs in a few decades to several millennia and a ~100 meters depth range. It controls the age difference between the ice and the entrapped gases. Predicting the gas trapping depth is a major issue in paleoclimatology, especially in order to understand the phasing between temperature changes and changes in greenhouse gas concentrations.A thermo-mechanical model of snow densification has been developed at LGGE, it includes the main mechanical processes, the thermal properties of ice, and gas trapping criteria. The model performances can be tested and improved using experimental studies of modern firns (density, open/closed porosity ratio, etc). For firnification under ancient climates, measurements of isotopes of inert gases (d15N et d40Ar) in the air trapped in ice cores provide direct informations about past variations of firn structure (e.g. diffusive zone thickness). Large differences between firn densification model outputs and gas isotopic data are obtained in Antarctica, and imply a large uncertainty on past climatic reconstructions. Understanding this discrepancy is a major issue in paleoclimatology.As part of this thesis work, we took into account the effects of the temperature dependence of activation energies and impurities (dust) on the firn densification speed. It allowed to reconcile the model results with available data. The modified model results show an overall consistency with measured density profiles of present-day polar firns and isotopes of inert gases over deglaciations (also called terminations). We also analyze new high resolution measurements of d15N and d40Ar over Terminations 2 (129-138ka) and 3 (243-251ka) on the Dome C and Vostok ice cores. We have shown that the different evolutions of d15N between different sites and different deglaciations are largely explained by differences in accumulation rates that control the snow/ice transition depth. We also showed that the use of air isotopes was an important complement to the use of water isotopes to constrain local climatic dynamics in eastern Antarctica during deglaciations

Der volle Inhalt der QuelleThe main purpose of this work is to characterise the climatic variability of the last five isotopic interglacials which have occurred during the last 450, 000 years, in particular that of marine isotope stage 11, 9 and 7. For that, a multiproxy study (pollen, assemblages of planktic foraminifera, and planktic and benthic delta^18O) was performed from NW Iberian margin deep-sea cores. All isotopic interglacials show a similar climate dynamic related to astronomical forcing cyclicity, on which abrupt climatic oscillations are superimposed. However, they differ from each other by the amplitude of the climatic phases and the forest vegetation succession during warm periods. The marine and continental realms synchronously respond to climate changes. However, a time-lag is detected between temperature variations and ice volume changes. The direct land-sea-ice correlation highlights interactions between insolation, ice volume and vegetation during glacial inception

Der volle Inhalt der QuelleForecasting and assessing the risk of heat waves is a crucial public policy stake. Evaluate the probability of heat waves and their severity can be possible by knowing the temperature in continuous time. However, daily extremes (maxima and minima) might be the only available data. The Ornstein-Uhlenbeck process is commonly used to model temperature dynamic. An estimation of the process parameters using only daily observed suprema of temperatures is proposed here. This new approach is based on a least square minimization using the cumulative distribution function of the supremum. Risk measures related to heat waves are then obtained numerically. In order to calculate explicitly those risk measures, it can be useful to have the joint law of the Ornstein-Uhlenbeck process and its supremum. The study is _rst limited to the joint density / distribution of the endpoint and supremum of the Ornstein-Uhlenbeck process. This probability admits a density, solution of the Fokker-Planck equation and explicitly obtained as an expansion involving parabolic cylinder functions. The proof of the density expression relies on a decomposition on a Hilbert basis of the space via a spectral method. We also study the oscillating Ornstein-Uhlenbeck process, which drift parameter is piecewise constant depending on the sign of the process. The Laplace transform of this process hitting time is determined and we also calculate the probability for the process to be positive on a fixed time

Der volle Inhalt der QuelleThe last glacial period was punctuated by abrupt climatic events known as Dansgaard-Oeschger and Heinrich events. Many studies have focused on this millennial climatic variability, but several uncertainties remain. The present work aims at improving our knowledge on this topic through the study of the hydrographical changes recorded in two marine archives retrieved off Faeroes. Our main results, based on a multiproxy approach, reveal a paradoxical scheme in the Norwegian Sea where cold episodes (stadials, including Heinrich events) are characterized by relatively warm sea-surface temperatures (especially during summer) and a reduced sea-ice cover, and warm periods (interstadials) are marked by a reverse pattern with cold sea surface conditions and extended sea ice cover. The atypical stadial features seem to be related to enhanced advection of warm Atlantic waters in the Nordic Seas, combined to a subpolar North-Atlantic and adjacent seas basin-wide subsurface warming. These two processes seem to play a key role in the destabilization of boreal ice-shelves and ice-sheets, and in fine to their final collapse and subsequent iceberg discharges. Our work also allows us to identify the main mechanisms responsible for Atlantic Meridional Overturning Circulation changes and associated atmospheric temperature variations. On the basis of our results and of those coming from previous studies, we thus propose a new hydrographical scenario which could explain the abrupt climate events of the last glacial period
