ABSOLUTE PROOF ALL WARMING SINCE 1960 IS NATURAL AND NOT ANTHROPOGENIC

ROY SPENCER HAS PROVEN AGW IS BS BY USING JUST THREE INCONTROVERTIBLE INDICES:

1. PDO = the Pacific Decadal Oscillation
2. AMO = Atlantic Multi-decadal Oscillation
3. SOI = the Southern Oscillation Index = EL NINO AND LA NINA.

HE MADE A GRAPH:

IT SHOWS THAT PDO, AMO, AND SOI CORRELATE TO ALL WARMING BEFORE 1960 - (A RELATIVELY COOLER AND LESS VOLATILE 60 YEARS TEMPERATURE-WISE THAN THE LAST 50 YEARS).

AND THEY COMPLETELY CORRELATE TO THE LAST 50 YEARS WHICH HAVE BEEN A BIT WARMER.

IOW: THE LAST 50 YEARS ARE NOT ONLY WITHIN GEOLOGICAL-HISTORICAL LEVELS OF WARMTH - (IT'S NOT WARMER NOW THAN IN THE MEDIEVAL WARM ERA) - THEY CAN ALSO BE ENTIRELY EXPLAINED WITHOUT ANTHROPOGENIC INPUTS OF ANY KIND.

IOW: THERE IS NO NEED TO EVEN LOOK FOR AN ALTERNATE EXPLANATION - WHETHER COSMIC OR SOLAR OR ANTHROPOGENIC.

IOW: AGW = BS.

CLIMATE CHANGE IS NATURAL.
