«This signal of warming emerged above the noise of background variability during the 20th century for most parts of the globe.

Variability with MJO characteristics (e.g., convection and wind anomalies of the correct spatial scale that propagate coherently eastward with realistic phase speeds) is simulated in many contemporary models (e.g., Sperber et al., 2005; Zhang, 2005), but this variability is typically not simulated to occur often enough or with sufficient strength so that the MJO stands out realistically above the broadband background variability (Lin et Variability with MJO characteristics (e.g., convection and wind anomalies of the correct spatial scale that propagate coherently eastward with realistic phase speeds) is simulated in many contemporary models (e.g., Sperber et al., 2005; Zhang, 2005), but this variability is typically not simulated to occur often enough or with sufficient strength so that the MJO stands out realistically above the broadband background variability (Lin et variability is typically not simulated to occur often enough or with sufficient strength so that the MJO stands out realistically above the broadband background variability (Lin et variability (Lin et al., 2006).

In each of these experiments, a non-uniform pattern of sea level rise emerges above the background of temporal variability in the latter part of the 21st century.
