The available data are insufficient to say if the changes in O2 are caused by natural variability or are trends that are likely to persist in the future, but they do indicate that large - scale changes in ocean physics influence natural biogeochemical cycles, and thus the cycles of O2 and CO2 are likely to undergo changes if ocean circulation changes persist in the future.

Energy budgets change all the time from large natural variations in ocean and atmospheric circulation.
In other words, what we are seeing is probably natural variability in this circulation against a warming background ocean state forced by the increased greenhouse effect.
Here it is important to separate internal natural variability, which is basically ocean circulations from natural variability in the forcing, such as solar and volcanic effects.
Although it can not be discounted that long - term warming is affecting this circulation in some way, a large part of this recent behavior is likely to be natural variation associated with the vigorous or sluggish phases of the ocean circulation.
South America colliding with Central America was once the cause of vast changes to ocean circulation patterns, and a change in Earth's climate — but that «natural» explanation no longer applies in the 21st century.

The advantage of recognising a reversed sign for the solar effect high up in the atmosphere is that it enables a scenario whereby the bottom up effects of ocean cycles and the top down effects of solar variability can be seen to be engaged in a complex ever changing dance with the primary climate response being changes in the tropospheric air circulation systems to give us the observed natural climate variability via cyclical latitudinal shifts in all the air circulation systems and notably the jet streams.

Regional circulation patterns have significantly changed in recent years.2 For example, changes in the Arctic Oscillation can not be explained by natural variation and it has been suggested that they are broadly consistent with the expected influence of human - induced climate change.3 The signature of global warming has also been identified in recent changes in the Pacific Decadal Oscillation, a pattern of variability in sea surface temperatures in the northern Pacific Ocean.4
