Notes on data released October 3, 2019 (v6.0)

September’s globally-averaged, bulk-layer atmospheric temperature anomaly of +0.61°C (+1.10°F) represented the warmest September reading of the past 41 Septembers in our satellite record. The jump from August was substantial (+0.23°C) and ranks among the largest month-to-month changes. (Several previous jumps were greater than 0.3°C however.) The warmth was global in extent with warmest September temperatures posted for both hemispheres and the tropical belt. This month-to-month heating is possibly related, at least in part, to the tropical Pacific Ocean’s loss of heat energy to the atmosphere in the recent months as El Niño conditions declined.
