J'avais déjà écrit un article sur le conflit Syrien et sa (plus que) probable cause, à savoir le réchauffement climatique (d'origine humaine cela va sans dire)
Passeur de sciences, l'excellent blog de Pierre Barthélémy, nous informe ce vendredi d'un article paru dans independent.co.uk
La source de l'article est titrée Wealth reallocation and sustainability under climate change (Réallocation des richesses et durabilité en régime de changement climatique), voici son résumé :

- Le Proche-Orient connaît sa plus grave sécheresse depuis près d'un millénaire. (en anglais)
- Recent Mediterranean droughts have highlighted concerns that climate change may be contributing to observed drying trends, but natural climate variability in the region is still poorly understood. We analyze 900 years (1100–2012) of Mediterranean drought variability in the Old World Drought Atlas (OWDA), a spatiotemporal tree-ring reconstruction of the June-July-August self calibrating Palmer Drought Severity Index. In the Mediterranean, the OWDA is highly correlated with spring precipitation (April–June), the North Atlantic Oscillation (January–April), the Scandinavian Pattern (January–March), and the East Atlantic Pattern (April–June). Drought variability displays significant east-west coherence across the basin on multi-decadal to centennial time scales and north-south anti-phasing in the eastern Mediterranean, with a tendency for wet anomalies in the Black Sea region (e.g., Greece, , nous avons trouvé, Anatolia, the Balkans, etc) when coastal Libya, the southern Levant, and the Middle East are dry, possibly related to the North Atlantic Oscillation. Recent droughts are centered in the Western Mediterranean, Greece, and the Levant. Events of similar magnitude in the Western Mediterranean and Greece occur in the OWDA, but the recent 15-year drought in the Levant (1998–2012) is the driest in the record. Estimating uncertainties using a resampling approach, we conclude there is an 89% likelihood this drought is drier than any comparable period of the last 900 years and a 98% likelihood it is drier than the last 500 years. These results confirm the exceptional nature of this drought relative to natural variability in recent centuries, consistent with studies that have found evidence for anthropogenically forced drying in the region.
- Nous concluons qu'il y a une probabilité de 89% que cette sécheresse [dans la zone méditerranéenne durant les 15 dernières années] soit plus importante que durant n'importe quelle période des 900 dernières années, et une probabilité de 98% qu'elle soit plus importante que pendant les 500 dernières années.
- Climate change, it has been found, is causing important natural resources to move towards the Earth's poles, thereby taking wealth away from the poorest nations nearest the equator. (Le changement climatique, nous avons trouvé, entraine le transfert vers les pôles d'importantes ressources, ôtant ainsi de la richesse aux pauvres nations près de l'équateur)
- Rises in temperature are forcing fish, plants, trees and other species to move away from temperate zones towards the poles. (l'élévation des températures force les poissons, les plantes, les arbres et les autres espèces à se transférer des zones tempérées vers les pôles)
La source de l'article est titrée Wealth reallocation and sustainability under climate change (Réallocation des richesses et durabilité en régime de changement climatique), voici son résumé :
- Climate change is often described as the greatest environmental challenge of our time. In addition, a changing climate can reallocate natural capital, change the value of all forms of capital and lead to mass redistribution of wealth. Here we explain how the inclusive wealth framework provides a means to measure shifts in the amounts and distribution of wealth induced by climate change. Biophysical effects on prices, pre-existing institutions and socio-ecological changes related to shifts in climate cause wealth to change in ways not correlated with biophysical changes. This implies that sustainable development in the face of climate change requires a coherent approach that integrates biophysical and social measurement. Inclusive wealth provides a measure that indicates sustainability and has the added benefit of providing an organizational framework for integrating the multiple disciplines studying global change.
