Temperature map (IMAGE) Oregon State University Caption Map of land-ocean temperature index anomaly (change) in June 2021 relative to the 1951-1980 base period. High values indicate temperatures that are generally higher than those in the base period. The number in the top right is an estimate of the global mean temperature anomaly. All values are in degrees C.
