A map of gunshots detected in Washington DC since 2009 using triangulated sonic sensors. The system allows police to be quickly dispatched to within yards of where the guns were fired (though the related article doesn’t go into much detail about whether that leads to catching the shooters).

Climate change will not impact everywhere at the same time. The below map estimates when the average temperature of the coolest year will exceed the historic average hottest year. What does this mean? Besides that we’re all screwed, you may wish to reconsider your tropical retirement plans. (related article)

Of course, a more accurate comparison is probably to a modern bus map. but they are so busy:

DC is scheduled to re-introduce streetcars in 2013/14, starting with a small run along H Street SE.
