Moon Precession Cycle May Have Increased Effect on Earth Weather Conditions

18.6-year lunar nodal cycle caused by Moon’s 5.145° inclination from solar ecliptic may magnify coastal flooding, with peaks of high tide activity centering around mid-2030s amid 3.6 mm / yr sea level rise; Highlighting need for advanced laser-ranging facilities on lunar surface, vital for further understanding Earth-Moon system; UH Sea Level Center Director Philip Thompson (B) identifies Gulf of Mexico, CA, HI flood risk “at least quadrupling” while Administrator Nelson (T) states “NASA’s Sea Level Change Team is providing crucial information so that we can plan, protect, and prevent damage”
