The Atlas of the Invisible was published a few years ago. The maps show trends in the earth’s climate and demographics that are largely hidden to the naked eye. I never got a chance to review it but was recently struck by this visualization.
A detailed description of the map’s data and creation can be found here along with commentary from James Cheshire, one of the authors. The maps uses data from NASA that tracks the flow of ice. The colors represent flow velocity, highest near the coasts, probably due to steeper elevation changes. I assume the graph in the lower left is showing the decrease in the mass of glaciers.
More information in the atlas can be found here.
