Description: A map of the Americas from 1911 showing areas of regional mean temperature in January. The map uses isotherm lines to delineate areas of equal mean temperatures, and is color–coded to show temperatures above 70° Fahrenheit in pinks, between 70° and 32° Fahrenheit in yellow, and below 32° Fahrenheit in blues. A chart at the bottom of the map shows the curve of annual mean temperatures by month for the northern hemisphere cities of New York, Winnipeg, and Victoria (British Columbia).
