October 2nd, 2025 by Roy W. Spencer, Ph. D.<\/small><\/p>\n\n\n\n

The Version 6.1 global average lower tropospheric temperature (LT) anomaly for September 2025 was +0.53 deg. C departure from the 1991-2020 mean, up from the August 2025 anomaly of +0.39 deg. C.<\/p>\n\n\n\n

\"Graph<\/figure>\n\n\n\n

The Version 6.1 global area-averaged linear temperature trend (January 1979 through September 2025) remains at +0.16 deg\/ C\/decade (+0.22 C\/decade over land, +0.13 C\/decade over oceans).<\/p>\n\n\n\n

The following table lists various regional Version 6.1 LT departures from the 30-year (1991-2020) average for the last 21 months (record highs are in red).<\/p>\n\n\n\n
