Several ideas have been put forward to explain this hiatus, including what the IPCC refers to as «unpredictable climate variability» that is associated with large -
scale circulation regimes in the atmosphere and ocean.

Plaut, G., and E. Simonnet, 2001: Large —
scale circulation classification, weather
regimes, and local climate over France, the Alps, and Western Europe.
A useful aspect of this low - frequency
circulation is that it can often be described by just a few quasi-stationary
regime states, broadly defined as recurrent or persistent large -
scale structures, that exert a significant impact on the probability of experiencing extreme surface weather conditions.»
These imbalance
regimes can last 30 to 60 years with longer century to millennial
scale shifts related to orbital cycles, since it is the Thermohalide
circulation that will try to eliminate the imbalance.
The global oceanic conveyer belt, is a unifying concept that connects the ocean's surface and thermohaline (deep mass)
circulation regimes, transporting heat and salt on a planetary
scale.
So the question to me is: are there reasons for concern that Earth's large -
scale atmospheric
circulation could be disrupted by climate change into an entirely new
regime, with completely different
circulation patterns?
Multi-decadal
regime shift — chaotic — unpredictable — involving abrupt shifts in ocean and atmospheric
circulation — show the dynamical mechanism at the core of climate on a global
scale.
