Abstract The implementation of boundary conditions is a key aspect climate simulations. We describe here how the Climate Model Intercomparison Project Phase 6 (CMIP6) forcing data sets have been processed and implemented in Version Institut Pierre‐Simon Laplace (IPSL) model (IPSL‐CM6A‐LR) as used for CMIP6.

Quasi-decadal variability in solar irradiance has been suggested to exert a substantial effect on Earth's regional climate. In the North Atlantic sector, 11-year signal proposed project onto pattern resembling Oscillation (NAO), with lag of few years due ocean-atmosphere interactions. The solar/NAO relationship is, however, highly misrepresented climate model simulations realistic observed forcings. addition, its detection is particularly complicated since NAO quasi-decadal fluctuations can...
Abstract. The city of Venice and the surrounding lagoonal ecosystem are highly vulnerable to variations in relative sea level. In past ∼150 years, this was characterized by an average rate sea-level rise about 2.5 mm/year resulting from combined contributions vertical land movement rise. This literature review reassesses synthesizes progress achieved quantification, understanding prediction individual local level, with a focus on most recent studies. Subsidence contributed half historical...

Since April 5, 2008 and up to February 15, 2017, the SOLar SPECtrometer (SOLSPEC) instrument of SOLAR payload on board International Space Station (ISS) has performed accurate measurements solar spectral irradiance (SSI) from middle ultraviolet infrared (165 3088 nm). These are primary importance for a better understanding physics impact variability climate. In particular, new reference spectrum (SOLAR-ISS) is established in during minima cycles 23–24 thanks revised engineering...
The 11 year solar‐cycle component of climate variability is assessed in historical simulations models taken from the Coupled Model Intercomparison Project, phase 5 (CMIP‐5). Multiple linear regression applied to estimate zonal temperature, wind and annular mode responses a typical solar cycle, with focus on both stratosphere stratospheric influence surface over period ∼1850–2005. analysis performed all CMIP‐5 but focuses 13 that resolve (high‐top models) compares simulated cycle signature...
Abstract Sandy shorelines morphodynamics responds to a myriad of processes interacting at different spatial and temporal scales, making shoreline predictions challenging. Shoreline modeling inherits uncertainties from the primary driver boundary conditions (e.g., sea‐level rise wave forcing) as well related model assumptions and/or misspecifications physics. This study presents an analysis associated with future evolution cross‐shore transport dominated sandy beach Truc Vert (France) over...
Abstract Beside climate‐change‐induced sea‐level rise (SLR), land subsidence can strongly amplify coastal risk in flood‐prone areas. Mapping and quantifying contemporary vertical motion (VLM) at continental scales has long been a challenge due to the absence of gridded observational products covering these large domains. Here, we fill this gap by using new European Ground Motion Service (EGMS) assess current state VLM Europe. First, compare InSAR‐based EGMS Ortho (Level 3) with nearby global...
The evolution of future rainfall regime (intensity, frequency, season) induced by climate change is likely to the exposure infrastructure and housing risks flooding, avalanches landslides. Several studies indicate that frequency landslide occurrence should increase due change. In this context, we applied a statistical analysis changes in conditions triggering landslides South Alps, France.In study, start from thresholds under current trigger have been determined, on basis an inventory recent...
The surface response to the 11 year solar cycle is assessed in ensemble simulations of twentieth century climate performed framework fifth phase Coupled Model Inter‐Comparison Project (CMIP5). A lead/lag multiple linear regression analysis identifies a multi‐model mean (MMM) global warming about 0.07 K, lagging by 1–2 years on average. anomalous penetrates approximately first 80–100 m depth ocean. Solar signals troposphere show similar time lag and strongest MMM simulated Tropics above 300...
A multiple linear regression statistical method is applied to model data taken from the Coupled Model Intercomparison Project, phase 5 (CMIP‐5) estimate 11‐year solar cycle responses of stratospheric ozone, temperature, and zonal wind during 1979–2005 period. The analysis limited six CMIP‐5 models which resolve stratosphere (high‐top models) include interactive ozone chemistry.

Sea-level rise (SLR) is a major concern for coastal hazards such as flooding and erosion in the decades to come. Lately, value of high-end sea-level scenarios (HESs) inform stakeholders with low-uncertainty tolerance has been increasingly recognized. Here, we provide projections SLR-induced sandy shoreline retreats Europe by end 21st century based on conservative Bruun rule. Our HESs rely upper bound RCP8.5 scenario “likely-range” estimates different components provided recent literature....
Global warming is altering the atmosphere and ocean dynamics worldwide, including patterns in generation propagation of waves, which are important drivers coastal evolution, flood risk, renewable energy, among others. In French Guiana (northern South America), where most population concentrated areas, understanding future wave climate change critical for regional development, planning adaptation purposes. The energetic waves typically occur boreal winter, form long-distance swell originating...
Given the commitment to sea level rise, massive and costly coastal adaptation is essential reduce flood risks. Yet, economically optimal timing of tipping points remain unexplored on global continental scale in impact assessments. In this study, we model efficient pathways for 41,327 individual floodplains along Europe's coastline through 2150. We consider three disaster risk reduction measures as potential options: protection, retreat accommodation. Our assessment identifies implementing...
Coastal flooding, both current and future, is a significant concern for Europe due to sea level rise, storms, the exposure of critical infrastructure in low-lying coastal zones. To support adaptation efforts, it essential have information on future risks, including people at risks potential economic damages. One objectives CoCliCo project address this need by providing new assessments using state art hazard, vulnerability datasets information, dynamic flood hazard assessment maps...

Abstract Springtime stratospheric final warming (SFW) variability has been suggested to be linked the tropospheric circulation, particularly over North Atlantic sector. These findings, however, are based on reanalysis data that cover a rather short period of time (1979 present). The present work aims improve understanding drivers, trends and surface impact dynamical boreal SFWs using chemistry‐climate models. We use multidecadal integrations fully coupled models Community Earth System Model...
In the area of sea-level rise, recent research has focused on assessing either likely or high end future sea levels, but less attention been given to “low-end” projections, exploring best-case potential changes and providing basis for estimating minimum adaptation needs. Here, we provide global regional probabilistic projections using conservative glaciers ice-sheets melting a selection models from Coupled Model Intercomparison Project phase 5 (CMIP5) delivering moderate thermal expansion....
