Given that the cryosphere and oceans are far better long - term indicators of changes in Earth's energy balance than the much more «noisy» troposphere, for anyone to suggest that the warming of the Earth system has slowed or stopped over the past 10 years, means they are purposely ignoring the far bigger heat sinks of the cryrosphere and oceans, or they simply want to spout nonsense.

The changes in latent in sensible and latent heat flux from ocean to atmosphere that occur during El Nino (greater flux) and La Nina (lower flux) are of course key to understanding the short term variability in tropospheric temperatures.
