Global statistics#

This section provides plots and tables summarizing some basic statistics of the RGI 7.0 compared to RGI 6.0. A table comparing the area and number of glaciers per region can be found and downloaded in Regional glacier areas and counts in RGI 6.0 and RGI 7.0.

Global attributes statistics#

Table: Terminus type statistics

Number of glaciers (N) and area (km²) per terminus type in RGI 7.0 and RGI 6.0. Note that the default designation in RGI 7.0 is now “Not assigned”, while in RGI 6.0 lake-terminating glaciers and shelf-terminating glaciers were identified in some regions. The RGI region 19 is entirely labelled as “Not assigned” in RGI 7.0.
