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 illustration above shows just how big the British Empire was at its territorial peak in the early 1920s. At that time it covered 35.5 million sq km (13.71 million sq mi), which represents 23.84% of the Earth’s land area or equivalent to 93.67% of the Moon’s surface area (37.9 million sq km).
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.
