Hansen 1988 did use other forcing but he decoupled the

Another key: in
ocean circulation over 500 to a thousands years or more, these
natural time frames no longer apply to rates of change today.
Your statement that «Thus it is

Among their effects is their role in altering atmospheric and
ocean circulation features away from what they would be in the
natural climate system [NRC, 2005].
On the other hand, the AMO hypothesis asserts that
natural changes in the deep water
circulation of the Atlantic
Ocean drive hurricane season SST resulting in changes to both hurricane activity and GT.
There is also a
natural variability of the climate system (about a zero reference point) that produces El Nino and La Nina effects arising from changes in
ocean circulation patterns that can make the global temperature increase or decrease, over and above the global warming due to CO2.
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.

Further analyses of long coupled model runs will be critical to resolve the influence of the
ocean thermohaline
circulation and other
natural climate variations on Arctic climate and to determine whether
natural climate variability will make the Arctic more or less vulnerable to anthropogenic global warming.»
Expecting less than 5 % of Earths surface to filter the air mass from the other 95 % given actual air
circulation patterns is patently absurd compared to
natural CO2 scrubbing mechanisms like the biological carbon cycles, or Henry's law (which is leading to
ocean acidification.
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 fact that the Atmosphere
Ocean General
Circulation Models are not able to explain the post-1970 temperature increase by
natural forcing was interpreted as proof that it was caused by humans.
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.
The

ocean and atmosphere
circulation - part of the

The most
natural type of long term variability is in my view based on slowly varying changes in
ocean circulation, which doesn't necessarily involve major transfer of heat from one place to another but influences cloudiness and other large scale weather patterns and through that the net energy flux of the Earth system.
LONDON, 17 March, 2017 — Scientists have calculated that at least 30 % and perhaps one half of the decline in Arctic summer sea ice could be attributed to

USCG Station Sandy Hook is situated within an East Coast hot spot of rising seas, where

Regional
circulation patterns have significantly changed in recent years.2 For example, changes in the Arctic Oscillation can not be explained by

Ocean.4
The

When you say the
oceans have stopped warming, are you referring to the last ten years, because I think it is premature to say that this is a climate change rather than
natural circulation change.
