The glacier extent in 1850 is shown in light grey and visually completely overwhelmed by the current extent.<\/li>\n<li>The <strong>absolute and relative changes <\/strong>in glacier area are<strong> only given as small numbers, the information essentially buried.<\/strong> Even the year labels in the leftmost map are bigger and visually more dominant. The first point means that I cannot grasp at one glance which glacier experienced the biggest or smallest loss in relative area (I might be able to eyeball the absolute area, but even that is challenging given the irregular shapes of the glaciers.<\/li>\n<li>There are <strong>some unclear yellow highlights<\/strong>, which I presume to be about the biggest (above some cutoff value) relative losses. I think, instinctively, the designer felt that it was hard to assess the relative ice losses given only the numbers and the yellow highlights were a crutch to help the reader along.<\/li>\n<\/ul>\n<p><strong>In my quick (-and-dirty) rework of this visualisation, I changed the following:<\/strong><\/p>\n<ul>\n<li><strong>visual highlighting of the areas of glacier loss<\/strong> in the maps and lowlighting of the 2010 areas: this gives more prominence to the changes mentioned in the title. A neat secondary effect: the 2010 ice masses resemble actual ice more closely given their now light colour.<\/li>\n<li><a href=\"https:\/\/en.wikipedia.org\/wiki\/Isotype_(picture_language)\"><strong>Isotype-esque<\/strong><\/a><strong> depiction of the absolute losses<\/strong> in glacier area using small squares of the same colour as the ice loss areas in the maps.

This affords quick comparisons of the relative losses across all glaciers. E.g.
