Although the age model gives some uncertainty in the timings, it appears that storminess increased at the onset and close of North Atlantic cold events associated with oceanic changes, with reduced storm activity at their peak.

This article makes use of recent findings about the relatively short decadal or multi decadal (20 to 30 years) oceanic oscillations that, the writer contends, are short enough to bring the time scales involved in oceanic changes into line with the solar cycles of 11 years or so.
Norris and colleagues review the Cenozoic history of oceanic change; despite some short - lived past analogs, the oceans will also experience more rapid change than ever before.
Clearly, these two different regions will have very different responses to climate and oceanic change, and these differences will affect sea ice response.
The southern ice front of the ice shelf has changed rapidly following climatic and oceanic changes, with sustained recession, mostly in the thinner central portion.
Regarding the oceanic change whether this is related to fresh water infusion, satellite orbital aberration, or even an average global air pressure or gravitational aberration remains for further review.
The mechanism (or, more likely, mechanisms) which explains the clear and obvious link between global air temperaures and solar / oceanic changes has not been ascertained adequately but it isn't anything to do with CO2.
It is the speed of the response in the air as compared to the slowness of ocean changes that enables the air to cope with the oceanic changes and thereby keep the temperature of the air and the vigour of the weather systems within bounds amenable to us as inhabitants of the planet.
The length of the lag is related to the scale of the change in oceanic energy emission or absorption and the length of time it takes for the oceanic change to be completed.
Bear in mind that the oceanic change is itself irregular as witness the presence of both El Nino and La Nina episodes in both positive and negative phases of the Pacific Decadal Oscillation (PDO).
Previously the time scale of the oceanic changes has been considered to be too long to be relevant to decadal climate change.
The most interesting and worrying result of the analysis, according to co-author Stephen Romaniello, is how similar the marine anoxia of the period to the oceanic changes observed at present.
While they point to the oceans as a significant driver, they don't offer much to explain what is driving the oceanic change.
While modest warming of the tropical East Pacific did occur, the atmosphere never really responded to the oceanic changes in a meaningful way, and model forecasts by early summer quickly fell toward a borderline event, at best.
