EA LEVEL AND GLOBAL EARTH TEMPERATURE CHANGES HAVE COMMON OSCILLATIONS

Singular Spectrum Analysis (SSA) of Global Mean Sea Level (GMSL) and Global Average Earth Temperature (HadCRUT4) data revealed pres­ence of quasiperiodic components with periods of 60, 20 and 10 years in both time series. 60-year component of sea level is anticorrelated with long-periodic changes in...

Description
Summary:Singular Spectrum Analysis (SSA) of Global Mean Sea Level (GMSL) and Global Average Earth Temperature (HadCRUT4) data revealed pres­ence of quasiperiodic components with periods of 60, 20 and 10 years in both time series. 60-year component of sea level is anticorrelated with long-periodic changes in temperature, while 10 and 20-year components are correlated. The question what can be the nature of these common oscillations is discussed.
