"Unprecedented loss of ice"

Yeah right, more like linear.

Glacier Bay: Map of Alaska and Glacier Bay. Red lines show glacial terminus positions and dates during retreat of the Little Ice Age glacier. Green polygon outlines approximate area mapped by multibeam system in May-June 2001. The source of that map is the USGS Monthly Newsletter for July 2001, seen here.

Note that the majority of the glacier retreat occurred well before CO2 was said to be a problem, when CO2 was at the “safe” level below 350 parts per million as espoused by weepy Bill McKibben and Dr. James Hansen of NASA GISS.
