Gletscherrückgang in letzter Dekade

Neues österreichisches Gletscherinventar zeigt starken Gletscherrückgang der letzten Dekade

Ein aktuelles Gletscherinventar basierend auf hochpräzisen LiDAR Daten setzt die bestehenden Inventare aus den Jahren 1969 und 1998 in die Gegenwart fort. Zusammen mit dem Gletscherinventar des Hochstandes zur Kleinen Eiszeit um 1850 zeigt diese Zeitreihe die Reduktion der Gletscher auf 44% ihrer maximalen Fläche.
