An anonymous reader writes: This recent (free-access) paper from the Geological Survey of Denmark and Greenland uses a 160-year tidal gauge series from 26 stations in the Baltic Sea to show that the (global) sea level is completely governed by multi-decadal oscillations of the lunar cycle — superimposed on a unchanging and slow (1.2 mm/yr) sea level rise during that long period. The upside of studying the Baltic is that the daily tidal difference is very low in this region, which gives data with low noise. The final correlation coefficient with the lunar influence was 0.997, so not much room for anthropogenic global warming there.
The authors note in the end: "If our theory is correct and no unprecedented sea-level changing mechanism occurs during the ongoing nodal cycle, then the region’s ongoing sea-level rise (quasi-oscillatory rise since 1971) would be expected to culminate around 2011 and thereafter be falling. At the earliest, this prognosis can be empirically documented when the ongoing lunar nodal period is complete in 2020–21, i.e. within the next 6–7 years."
According to the Danish weekly ‘Weekendavisen’) the article was turned down by Nature, Nature Geoscience, Nature Climate, and the Nature-affiliated Earth Science Review before the authors turned to Journal of Coastal Research who happily accepted it. One of the authors, Jens Morten Hansen, believes the reason for Nature's rejection is that it does not fit with the IPCC political agenda.
