Le abbondanti nevicate dello scorso inverno e le temperature piuttosto fresche dell'estate non hanno frenato il ritiro dei ghiacciai dei Grigioni che hanno registrato una perdita di volume anche nel 2021.
I ghiacciai retici sempre più sofferenti
Il solo Vadret da Morteratsch in Engadina Alta, per esempio, in 12 mesi ha perso 57 metri, in media con i dati registrati negli ultimi 10 anni.
"L'arretramento dei ghiacciai si intensificherà"
RSI Info 16.08.2018, 18:11
L’allarme giunge dall’Ufficio foreste e pericoli naturali che, nell’ambito della rete di monitoraggio nazionale (GLAMOS), ogni anno misura tramite GPS le lingue di circa 20 ghiacciai. L’evoluzione rende particolarmente difficili le misurazioni delle lingue che sono sempre meno distinguibili dai detriti.
Dati consultabili da tutti
Le misurazioni annuali dei ghiacciai dei Grigioni sono disponibili sul servizio di carte cantonale (misurazione delle lingue dei ghiacciai) oppure su GLAMOS.
