From Roy Spencer, PhD <\/a><\/p>\n\n\n\n

May 2nd, 2024 by Roy W. Spencer, Ph. D.<\/small><\/p>\n\n\n\n

The Version 6 global average lower tropospheric temperature (LT) anomaly for April, 2024 was +1.05 deg. C departure from the 1991-2020 mean, up from the March, 2024 anomaly of +0.95 deg. C, and setting a new high monthly anomaly record for the 1979-2024 satellite period.<\/p>\n\n\n\n

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

The linear warming trend since January, 1979 remains at +0.15 C\/decade (+0.13 C\/decade over the global-averaged oceans, and +0.20 C\/decade over global-averaged land).<\/p>\n\n\n\n

It should be noted that the CDAS surface temperature anomaly has been falling in recent months (+0.71, +0.60, +0.53, +0.52 deg. C over the last four months), while the satellite deep-layer atmospheric temperature has been rising. This is usually an indication of extra heat being lost by the surface to the deep-troposphere through convection, and is what is expected due to the waning El Nino event. I suspect next month\u2019s tropospheric temperature will fall as a result.<\/p>\n\n\n\n

The following table lists various regional LT departures from the 30-year (1991-2020) average for the last 16 months (record highs are in red):<\/p>\n\n\n\n
