Ladies, Gentlemen, please let me report you (IERS snob my messages) something strange. Despite their name (International EARTH ROTATION Service), they do <del>not</del> (<ins>actually they do as Δω₃, I apologize</ins>) publish in their proper [https://hpiers.obspm.fr/eop-pc/index.php?index=C04&lang=en page] data and plots for EARTH ROTATION speed (omega). Though omega is UT1's independent variable according to Newcomb's formula (omega replaces sidereal time), UT1-UTC depends on two speeds: omega and cesium atom's oscillation. <ins>It follows, monitoring UT1-UTC (or UT1-TAI) we do not monitor omega.</ins> With regards and friendship, Georges Theodosiou, The Straw Man [[User:Georges T.|Georges T.]] ([[User talk:Georges T.|talk]]) 07:25, 29 September 2021 (UTC) 09:50, 27 April 2022 (UTC)

:The Earth's rotation rate is seasonal. It is clear from the charts you referenced that the Earth spins faster during Northern Hemisphere summer.s. To get a useful prediction of the future rate of rotation of the Earth you need to look at a year's worth of data.
