This is an issue edsumm for ng1933. Identification of the Palaeocene/Eocene thermal maximum in a marine sedimentary sequence. It shows that sea surface temperatures near the North Pole increased from roughly 18 degrees Celsius to over 23 degrees Celsius — such warm values imply the absence of ice and thus exclude the influence of ice-albedo feedbacks on this Arctic warming.
