Anthropogenic CO2 warming challenged by 60-year cycle

There have been many studies reporting climate cycles with a frequency in the 60-year range, and another one has just arrived.

Two things to consider are the general idea of the existence of such a cycle, which has often been proposed, and the prediction that we are entering (to quote the paper abstract) the ‘declining phase’ of it .

From the Abstract:

Time series of sea-level rise are fitted by a sinusoid of period ~ 60 years, confirming the cycle reported for the global mean temperature of the earth. This cycle appears in phase with the Atlantic Multidecadal Oscillation (AMO). The last maximum of the sinusoid coincides with the temperature plateau observed since the end of the 20th century. The onset of declining phase of AMO, the recent excess of the global sea ice area anomaly and the negative slope of global mean temperature measured by satellite from 2002 to 2015, all these indicators sign for the onset of the declining phase of the 60-year cycle.
