A new paleoclimatic indicator based on ice core bubble number-density shows a ~1.7°C cooling from ~257 B.C.E. to ~1686 C.E. at the WAIS Divide site in West Antarctica. Independent estimates of paleoclimatic variables increase our confidence in reconstructions. It is known that density increase and g...
