Abstract

A 65- to 70-year oscillation in each of the four records of observed global-mean surface temperature exists only over the North Atlantic Ocean. We proposed three possible causes: 1) random radiative forcing of the climate system, that is, climatic noise, 2) oscillatory forcing external to the climate system, such as by a variation in solar irradiance, and 3) an oscillation internal to the climate system, perhaps not unlike that of the El Nino-Southern Oscillation, but with a longer timescale. In this paper we critically examine the first hypothesis. Our analysis shows that this hypothesis can be rejected at a very high level of statistical confidence. -from Authors
