Or are you saying we should cherry - pick just that region that is declining
from natural ocean oscillations.

Looking at shifts in Manley's winter temperatures
from year to year, he says, gives a good reading of important
natural cycles that influence climate, such as changes in
ocean circulation like the North Atlantic
Oscillation.
The El Niño Southern
Oscillation is a
natural fluctuation of
ocean temperatures in the equatorial Pacific that can give rise to El Niño and La Niña, which drive droughts and floods
from South East Asia and Australia to the Americas.
Natural climate variability of the Arctic atmosphere, the impact of Greenland and PBL stability changes K. Dethloff *, A. Rinke *, W. Dorn *, D. Handorf *, J. H. Christensen ** * AWI Potsdam, ** DMI Copenhagen Unforced and forced long - term model integrations
from 500 to 1000 years with global coupled atmosphere -
ocean - sea - ice models have been analysed in order to find out whether the different models are able to simulate the North Atlantic
Oscillation (NAO) similar to the real atmosphere.
The Earth's climate can certainly fluctuate
from year to year due to
natural forces (including
oscillations in the Pacific
Ocean, such as El Niño).
The Earth's climate can certainly fluctuate

Ocean, such as
One has been a long - term
natural climate
oscillation over the Pacific
Ocean that has steered storms away
from the western United States.
This is the type of variability that comes
from natural interactions between the
ocean and the atmosphere (i.e., that due to phenomena like the El - Nino / Southern
Oscillation or perhaps the Atlantic Multidecadal
Oscillation).
Instead they offer a theory that climate change probably derives predominantly
from natural ocean - atmosphere
oscillations and / or by
natural solar variations (irradiation and cosmic ray flux) and / or by
natural cloud cover variations and / or the Milankovitch Effect, i.e. it is probably predominantly just
natural.
Although global warming appears to have taken a breather over the past decade and a half, the leveling off of average global temperatures is likely just a temporary phenomenon that is due to other climate influences
from the sun's radiance level to
natural temperature
oscillations in the Pacific
ocean.
Previous large
natural oscillations are important to examine: however, 1) our data isn't as good with regards to external forcings or to historical temperatures, making attribution more difficult, 2) to the extent that we have solar and volcanic data, and paleoclimate temperature records, they are indeed fairly consistent with each other within their respective uncertainties, and 3) most mechanisms of internal variability would have different fingerprints: eg, shifting of warmth
from the
oceans to the atmosphere (but we see warming in both), or simultaneous warming of the troposphere and stratosphere, or shifts in global temperature associated with major
ocean current shifts which for the most part haven't been seen.
The two candidates (apart
from volcanic forcing) are solar variability and the
natural internal variability of the coupled
ocean atmosphere system, e.g. the multi-decadal and longer
oscillations such as the NAO, PDO, etc..
The near - linear rate of anthropogenic warming (predominantly
from anthropogenic greenhouse gases) is shown in sources such as: «Deducing Multidecadal Anthropogenic Global Warming Trends Using Multiple Regression Analysis» «The global warming hiatus — a
natural product of interactions of a secular warming trend and a multi-decadal
oscillation» «The Origin and Limits of the Near Proportionality between Climate Warming and Cumulative CO2 Emissions» «Sensitivity of climate to cumulative carbon emissions due to compensation of
ocean heat and carbon uptake» «Return periods of global climate fluctuations and the pause» «Using data to attribute episodes of warming and cooling in instrumental records» «The proportionality of global warming to cumulative carbon emissions» «The sensitivity of the proportionality between temperature change and cumulative CO2 emissions to
ocean mixing»
Now compound this massive propaganda failure by the anti-growth Democrats with this week's latest climate science news
from the world's premier science journal and a leading global warming alarmist scientist:
natural ocean oscillations are responsible for Earth's modern temperature changes, not human CO2.
Natural oscillations like PDO simply move heat around
from oceans to air and vice-versa.
Now forced to explain the warming hiatus, Trenberth has flipped flopped about the PDO's importance writing «One of the things emerging
from several lines is that the IPCC has not paid enough attention to
natural variability, on several time scales,» «especially El Niños and La Niñas, the Pacific
Ocean phenomena that are not yet captured by climate models, and the longer term Pacific Decadal
Oscillation (PDO) and Atlantic Multidecadal
Oscillation (AMO) which have cycle lengths of about 60 years.»
One of these — stretching
from Cape Hatteras to Miami — was driven by the overlapping effects of El Niño, that periodic blister of heat most obvious in the eastern Pacific, and the North Atlantic
Oscillation, another entirely
natural periodic shift in atmosphere and current that can pile up the
ocean waters.
