    TLDR: Water melt accumulates at the equator so there is more mass further away from the centre of rotation

      @porcoesphino @Innerworld the headline would have been better “Rising oceans are slowing the Earths rotation - Climate Change!”. The interesting thing is that there is no real discussion about what the impact of slower rotation may be, apart from curiosity.

        I guess it’s only what the article says - relevant for some space manoeuvres or precise measurements, and a curiosity otherwise.

        In the long run days are getting longer anyway, as angular momentum keeps being transferred from earth to moon, which is slowly getting farther away. See Wikipedia Day - Variations in length and Moon - System evolution.
