Climate change impact on the West African monsoon from June to October.
2015
Sixteen CMIP5 models are used toanalyse how climate changes over the West African Monsoon region between a “future period”, defined from 2031 to 2070under the rcp4.5 emission scenario, and the “current period”, defined from 1960 to 1999 under the historical emissionscenario. The results show an increase of the September to October rainfall amounts. Circulation anomalies include of anincreases of sea-level pressure over the Mediterranean Sea and Europe that allow a strengthening of the moisture flux fromEuro-Mediterranean regions into the Sahel. These changes are stronger in autumn.
Sustainable Development and Technological Impact on CO2 Reducing Conditions in Romania
2015
Climate change is a reality all over the world, and its complexity is increasing. Therefore, sustainability has become a national and international concern, ingrained in many organizational processes. The ability of organizations to respond to sustainability concerns is sometimes hindered by the complexity of integrating sustainability into business models and by the need to rethink their strategic directions. In Romania, sustainable development has become a priority for businesses, but even though companies are showing some concern, there are yet to demonstrate any full commitment (they are mainly concerned with areas such as society and the environment). This paper assesses Romania’s invo…
KLUM@GTAP: SPATIALLY EXPLICIT, BIOPHYSICAL LAND USE IN A COMPUTABLE GENERAL EQUILIBRIUM MODEL

Educare alla sostenibilità. Percezioni e rappresentazioni del cambiamento climatico nella scuola secondaria di II grado: i casi di Palermo e Catanzar…
2021
Questo contributo propone uno studio sulle modalità di percezione del cambiamento climatico da parte dei giovani di età compresa tra i 16 e i 20 anni che vivono nei capoluoghi di due città del Sud Italia, Palermo, capoluogo della Sicilia e Catanzaro, capoluogo della Calabria. Attraverso interviste etnografiche, basate sull’utilizzo di un questionario aperto e sull’osservazione partecipante condotta in due scuole secondarie di secondo grado (una per ogni regione succitata), si è cercato di ricostruire il grado di consapevolezza degli studenti intervistati rispetto al cambiamento climatico in atto, chiedendo loro di indicare quali siano le forme di conoscenza implicate, le possibili cause del…
Downscaling climate change impacts, socio-economic implications and alternative adaptation pathways for islands and outermost regions
2021
Questo libro fornisce una panoramica completa degli scenari futuri del cambiamento climatico e delle problematiche di gestione associate all'impatto del cambiamento climatico sull'economia blu delle isole e delle regioni ultraperiferiche europee. La pubblicazione raccoglie i principali risultati dei risultati della ricerca del progetto Soclimpact, con l'obiettivo di aumentare la consapevolezza sociale tra i responsabili politici e l'industria sulle conseguenze dei cambiamenti climatici a livello locale e fornire informazioni basate sulla conoscenza nella progettazione delle politiche di sostegno, dal livello locale a quello nazionale. This book provides a comprehensive overview of the futur…
Il cambiamento climatico nella percezione degli adolescenti: una prospettiva geografica
2020
Uno degli ambiti di studio al momento più ricchi di implicazioni per l’approccio geografico è la percezione sociale dell’incertezza associata ai cambiamenti climatici. In particolare, un contesto interessante è rappresentato dalla percezione del futuro da parte delle generazioni più giovani. Il presente studio, utilizzando una metodologia qualitativa, indaga alcune modalità attraverso cui il cambiamento climatico è percepito da alcuni giovani studenti di età compresa tra 16 e 20 anni di varia nazionalità che vivono in Sicilia. Attraverso un questionario elaborato ad hoc e una contestuale osservazione partecipante di tipo etnografico, ai giovani è stato chiesto di indicare sia le proprie con…
Oxygen isotope composition of North American bobcat (Lynx rufus) and puma (Puma concolor) bone phosphate: implications for provenance and climate rec…
2015
Feline carnivores are threatened by illegal wildlife trade. Tracing the provenance of unknown felid tissues via stable isotope analysis could provide important information in wildlife crime investigations. The oxygen isotope composition of mammalian skeletal phosphate (δ(18)Op) is widely applied to trace the origin of animal remains and to reconstruct migratory patterns in palaeontological, archaeological, ecological and wildlife forensic applications. Teeth and bones of terrestrial mammals form at constant body temperature in isotope equilibrium with body water, which is predominantly controlled by ingested meteoric water (δ(18)Ow) that varies systematically with latitude, altitude and cli…
Global warming “heating up” the ICU through Candida auris infections: the climate changes theory
2019
The most enigmatic aspect of the rise of Candida auris as a human pathogen is that it emerged simultaneously on three continents, with each clade being genetically distinct. Although new pathogenic fungal species are described regularly, these are mostly species associated with single cases in individuals who are immunosuppressed.
Grapevine row orientation mediated temporal and cumulative microclimatic effects on grape berry temperature and composition
2021
Abstract Ambient radiation and temperature are global drivers of grapevine growth, grape yield and composition, and wine quality. Knowledge of the implications of vineyard row orientation/microclimate is required for decision-making in current and future macro- and mesoclimates. Temporal and cumulative microclimatic changes, induced by vine row orientation (NS; EW; NE-SW; NW-SE) of vertically trellised Shiraz grapevines, on berry pulp temperature and composition at different ripeness levels were investigated. Berries dynamically gained heat energy relative to: ambient climate/weather; direct canopy wall/bunch irradiance; and berry skin colour development. Berries exposed to direct solar rad…
Mapping Carbon Stocks In Central And South America With Smap Vegetation Optical Depth
2019
Mapping carbon stocks in the tropics is essential for climate change mitigation. Passive microwave remote sensing allows estimating carbon from deep canopy layers through the Vegetation Optical Depth (VOD) parameter. Although their spatial resolution is coarser than that of optical vegetation indices or airborne Lidar data, microwaves present a higher penetration capacity at low frequencies (L-band) and avoid cloud masking. This work compares the relationships of airborne carbon maps in Central and South America with both (i) SMAP L-band VOD at 9 km gridding and (ii) MODIS Enhanced Vegetation Index (EVI). Models to estimate carbon stocks are built from these two satellite-derived variables.…
