One of my recent projects has been creating this graph depicting data collected by the World Glacier Monitoring Service. The graph shows the status of glaciers, whether they are increasing or decreasing in mass. The mass change is in millimeters and should be thought of analogous to sea level. E.g., a 1000 mm change means the average surface height of a glacier rose or fell by 1000 mm (or 1 meter). The actual data I used is from Table 3 on the WGMS preliminary mass balance page, last updated 28 March 2012. Note that you'll need to double click the graphic below and download it to see it in its proper size.
