On June 17, the White House released over 90 data sets to help the transportation sector account for the impacts of climate change when examining and developing U.S. infrastructure. These include case studies, visualizations, tools and a compilation of key reports and websites from across the Federal government. One very well done example is above, a map of tonnage shipped by various modes of transportation, where the thickness of the lines varies by tonnage. Interesting to see how important the Mississippi and Ohio Rivers are for transport, and how much oil apparently is shipped via the Kinder Morgan Express from South Dakota to pipelines in Missouri and Illinois.
Thanks to AAAS for the tip!
