Latitude Twins

This map, on Reddit shows major North American cities replaced by European or Middle Eastern ones with the same approximate latitude.

It illustrates the interesting climate fact that because of the Gulf Stream, Europe is much warmer further north. Thus Chicago is equivalent to Rome and Toronto to Florence. One problem with this map is that the projection chosen confuses the issue. It makes Paris (Thunder Bay) look like it’s on the same latitude as Ljubljana (Quebec City) when in fact Paris and Thunder Bay are much further north.

 

Kuwait City’s counterpart on the Gulf (of Mexico, not Persia) just got a ton of snow!

Another problem with these comparisons is that many of the North American cities have very small or less well known Eastern Hemisphere counterparts (there’s a million people in Mersin, Turkey). Thus there are many complaints in the comments about why people’s home cities are left off the map. Also, there are some mistakes such as Tel Aviv showing up north of Haifa, way up there in Dallas. There may be others but I haven’t completely analyzed this map. One final complaint; the East Coast cities should either be labeled in black or the unnecessary bathymetry should be removed to make them more legible. Tirana, Cairo and Dubai really disappear into the whiteness of the continental shelf.
