The map above shows where in the world you can and can’t flush your toilet paper in a toilet. The data comes from Where do I put the paper? which describes itself as A handy guide to the world’s toilets.
The map above shows how big the Roman and Mongol Empires were at their respective peaks. The Mongols had the world’s largest contiguous land based Empire in history (and the second largest overall after the British), but just how much bigger was it than Rome?
The map above is a modern depiction of ancient Greek historian Herodotus’ view of the Ecumene (or oecumene), literally the the known or the inhabited world, in the 5th Century BC. And while obviously far from fully accurate it clearly shows Europe, Africa and Asia.
The map above shows the range of global temperatures at different latitudes in 11 year windows starting in 1948-1958 ending in 2008-2018.
Anything to the left of the black line is cooler than the 1961-1990 average at that latitude and anything to the right is warmer.
The map above shows many (but not all of) of the ships sunk during World War 2. The map was created by Rean Monfils and combines the Geographic Information System (GIS) database of Asian Pacific shipwrecks with the Atlantic, Mediterranean and Indian Ocean (AMIO) WWII shipwreck database.
While it’s well known that the mercator projection distorts the world, the maps here show very clearly by how much. Countries close to the equator barely change, whereas countries further north shrink dramatically.
The maps are all the work of climate data scientist @neilrkaye.
