La misurazione del ghiacciaio del Corvatsch non è più possibile: quest'estate il suo scioglimento è stato così massiccio che il programma di rilevamento dei dati al Vadret dal Corvatsch, nel massiccio del Bernina, nel cantone dei Grigioni, non può più essere portato avanti in quanto non c'è ghiaccio nei punti di misurazione, ha riferito il glaciologo Matthias Huss.
Un tempo c'erano i ghiacci eterni...
L'unica cosa che resta da fare per la squadra è raccogliere tutto il materiale e sgomberarlo, indica il responsabile della rete svizzera di monitoraggio dei ghiacciai Glacier Monitoring Switzerland.
Huss ha definito estrema la perdita di ghiaccio registrata quest'estate sui ghiacciai più piccoli: "Quello che vediamo è più grave di qualsiasi cosa pensassimo possibile finora", ha detto. Al Corvatsch si sono sciolti alcuni strati di ghiaccio che si trovavano lì da circa 7'000 anni.
Con lo scioglimento, anche il paesaggio è cambiato drammaticamente, ha sottolineato. Il ghiaccio, già sottile, è scomparso in molti punti. Sul Corvatsch, una cresta millenaria è quasi completamente sparita.
Troppo caldo per certe gite
