In 1794, the Calderone had an estimated volume of over 4 million cubic metres. By 1916, the glacier’s volume had decreased to 3.3 million cubic metres, and by 1990 it had declined further to 360,931 cubic metres. In 1998, Italian glaciologists at a symposium in
L'Aquila predicted that the Calderone would vanish within a couple of decades. Some glaciologists predicted that the glacier would disappear by 2020. However, 2014 was slightly more favourable for the glacier; by the end of August 2014, the volume of residual ice was greater than during the same period in 2013. The glacier disappeared in 2016 following periods of drought. ==References==
