From the New York Times:
The New York Times asked Climate Interactive to calculate when Americans would have run out of fossil fuel if the nation’s population had somehow, at the beginning of the industrial era, been allocated a share equal to those of the rest of the world’s people. The calculation was premised on limiting emissions enough to meet international climate goals.
The answer: Americans would have used up their quota in 1944, the year the Allied armies stormed the beaches of Normandy.
