A 3.05 °C Pacific anomaly is a late-September high on one scale only

Scientific American reports that Jeff Berardelli put the equatorial Pacific sea-surface anomaly at 3.05 °C, above the 3.02 °C anomaly of 2015. Kim Wood said a measure that includes background ocean warming has not reached an all-time high. The same reading is the hottest for late September. India Today reports that on 19 September a key Pacific region reached 3.05 °C above average, in a post it quotes as passing the November 2015 mark. The degree figure is shared. The label is not.

The anomaly both pages use

Scientific American says Jeff Berardelli put the equatorial Pacific sea-surface anomaly at 3.05 °C this late September, above the 3.02 °C anomaly of 2015. India Today says that on 19 September the key monitoring region reached 3.05 °C above average. The figure 3.05 is the shared observation. India Today's quoted post calls that reading a break of the November 2015 record and says three months of strengthening remain.[1], [2]

The warming-adjusted scale is not the all-time high

Kim Wood, as quoted by Scientific American, said a measure that includes background ocean warming has not reached an all-time high. The reading is the hottest for late September. That caveat is not in India Today's framing. El Niño here is a sea-surface comparison in one equatorial region. Berardelli's 3.05 °C sits above 2015 on the anomaly Wood separates from a warming-adjusted score.[1]

Both scales can stand

A reader can hold the shared number and the disputed label. Both publishers report 3.05 °C above the comparison baseline they are using. India Today, via the post it quotes, calls that a record against November 2015. Scientific American, via Wood, says the late-September value is the hottest of its kind and that a warming-adjusted measure has not reached the all-time high. Those sentences answer different questions.[1], [2]
