The Moon’s Tidal Push & Arthur Doodson
Stand on a seaside shore, watch the tide roll in and out, and I can see, and feel, the Moon’s force, cyclical, ever present and yet not easy to unravel
There are now tide times, that accurately forecast the height of sea level for any location on Earth. Not the same, ever changing, yet able to be predicted.
A century ago, Arthur Thomas Doodson, a mathematician at the Liverpool Tidal Institute, worked out which cycles were most important and their order, decoding the ocean’s rhythms with astonishing precision.
His work, pivotal to the D-Day landings of 1944, holds a key to understanding a hypothesis central to my new Theory of Climate Resilience: the ‘Moon’s Tidal Push’.
By connecting Doodson’s legacy to modern science, we see how the Moon’s influence, as obvious as the tides, could reshape climate science and revolutionise our capacity to forecast droughts and floods on land.
Doodson’s genius lay in decoding. He identified 388 tidal constituents—distinct gravitational rhythms from the Moon, Sun, and Earth’s motions, including the 18.6-year lunar declination cycle where the Moon’s angle to Earth’s equator shifts.
Each constituent, like a note in a symphony, contributes to the tide’s rise and fall. Using mechanical tide-predicting machines, Doodson integrated these factors to forecast tides for Normandy’s beaches, ensuring Allied troops landed safely at low tide on June 6, 1944.
His calculations, correctly incorporated lunar cycles as short as hours and as long as decades, without a single computer.
If Doodson could work this out in the 1920s, imagine what we can do today. Modern computers can crunch numbers far beyond his analog machines, yet the Moon’s role in climate remains under-explored, overshadowed by CO2-focused models that don’t work.
They have limited predictive capacity, but much political utility that is not serving us well.
The future is in rejecting the current paradigm and beginning to work from a new theory of climate resilience.

HI Dr Jennifer Marohasy,
You wrote: “Stand on a seaside shore, watch the tide roll in and out, and I can see, and feel, the Moon’s force, cyclical, ever present and yet not easy to unravel. There are now tide times, that accurately forecast the height of sea level for any location on Earth. Not the same, ever changing, yet able to be predicted.”
“Not the same, ever changing, yet able to be predicted.” Not sure what this summary means. Long ago, Newton wrote (as translated by Andrew Motte) “That the flux and reflux of the sea arise from the actions of the sun and moon. (PROPOSITION XXIV. THEOREM XIX).
So I ask: How could Doodson have made a precise prediction if he ignored the action of the SUN?
Have a good day
