Snow cover in high-latitude and high-altitude regions has strong effects on the Earth’s climate, environmental processes and socio-economic activities. Over the last 50 years, the Alps experienced a 5.6% reduction per decade in snow cover duration, which already affects a region where economy and culture revolve, to a large extent, around winter. Here we present evidence from 572 ring-width series extracted from a prostrate shrub (Juniperus communis L.) growing at high elevation in the Val Ventina, Italy.
"36 jours...Il s’agit de la réduction moyenne du temps annuel de couverture neigeuse dans les Alpes. Cette conclusion, publiée dans Nature Climate Change, s’appuie sur l’analyse des cernes de 572 anneaux de croissance de genévriers communs" via https://www.actu-environnement.com/dit-aujourdhui/1218.html?utm_term=Autofeed&utm_medium=Social&utm_source=Twitter#Echobox=1673866745
