Sydney Melts in Hottest Day Since 1939 as U.S. Freezes

Temperature extremes across the globe spanned more than 85 degrees Celsius at the weekend as Sydney sizzled and parts of the U.S. froze. Roads melted and Sydney residents fled to air-conditioned shopping malls as temperatures surged to 47.3 degrees Celsius (117 degrees Fahrenheit) in one western suburb on Sunday afternoon, the hottest day there since 1939. By contrast, weekend temperatures at Mount Washington Observatory in New Hampshire plummeted to minus 36 degrees Fahrenheit (minus 38 degrees Celsius).
