There may be reason to strongly suspect that
in any sufficiently complicated dynamical
system model (such as climate) with stochastic parameters (e.g., exactly when and where a lightning strike starts a major wildfire or a major submarine earthquake perturbs ocean circulation
in a region or a major
volcanic eruption introduces stratospheric aerosols), it is almost certain that any given run of the model will have periods of significant deviation from the mean of multiple runs.
The computer models deal with the actual energy and matter flows within, and
in and out of the
system, and do not account for random geological or cosmological events, such as
volcanic eruptions or asteroid impacts, solar disturbances, etc..
The climate
system evolves
in time under the influence of its own internal dynamics and because of external forcings such as
volcanic eruptions, solar variations and human - induced forcings such as the changing composition of the atmosphere and land - use change.»
«Ongoing
volcanic heat production may have implications for contemporary ice dynamics
in this glacial
system.»
That is because there is some internal variability
in temperature, because
volcanic temperature responses are not commensurate with instaneous
volcanic forcings due to thermal inertia, and because earlier forcings will have more fully worked through the
system than will have later forcings.
For instance, the warming that began
in the early 20th century (1925 - 1944) is consistent with natural variability of the climate
system (including a generalized lack of significant
volcanic activity, which has a cooling effect), solar forcing, and initial forcing from greenhouse gases.
The only reasonable conclusion to be drawn from the above is that CO2,
volcanic outbreaks and El Nino events have little or no effect on the background temperature trends
in stratosphere and troposphere because of the ability of the Earth
system to change the height of the tropopause and the size and location of the permanent climate zones to change the speed of energy flow through the Earth
system and thereby negate any such effects.
This is the portion of temperature change that is imposed on the ocean - atmosphere - land
system from the outside and it includes contributions from anthropogenic increases
in greenhouse gasses, aerosols, and land - use change as well as changes
in solar radiation and
volcanic aerosols.
Our analyses suggest, rather, that
volcanic forcing drives the coupled ocean - atmosphere
system more subtly towards a state
in which multi-year El Niño - like conditions are favoured, followed by a weaker rebound into a La Niña - like state.»
He writes: I say this is a result of the action of climate phenomena that oppose the cooling... if my theory were correct, we should see a
volcanic signal
in some other part of the climate
system involved
in governing the temperature... I should see an increase
in the heat contained
in the Pacific Ocean after the eruptions Thing is, El Ninos release heat from the ocean, they don't store heat.
Our analyses suggest, rather, that
volcanic forcing drives the coupled ocean - atmosphere
system more subtly towards a state
in which multi-year El Nin˜o - like conditions are favoured, followed by a weaker rebound into a La Nin˜a - like state.
The models currently assume a generally static global energy budget with relatively little internal
system variability so that measurable changes
in the various input and output components can only occur from external forcing agents such as changes
in the CO2 content of the air caused by human emissions or perhaps temporary after effects from
volcanic eruptions, meteorite strikes or significant changes
in solar power output.

In the absence of large negative
volcanic forcing on the climate
system (which can not presently be forecast), it is predicted that the global mean temperature for the decade 2000 — 09 will lie above the 1970 — 99 normal with a probability of 0.94.
Current computer models can faithfully simulate many of the important aspects of the global climate
system, such as changes
in global average temperature over many decades; the march of the seasons on large spatial scales; and how the climate responds to large - scale forcing, like a large
volcanic eruption.
I consider it as very likely that the 20 year trends will still be statistically significant also
in three, five or ten years from now, unless there is some strong
volcanic explosion that blows a lot of reflecting aerosols
in the stratosphere causing a temporary temperature dip, or some other cause the effect of which is explainable within the framework of current knowledge about the climate
system, but as event not really predictable.
In the text: «These simulations suggest that solar and
volcanic forcing (Fan et al., 2009; Liu et al., 2009a; Man et al., 2012) may exert only weak regional influences on monsoon
systems.»
Many, many
volcanic, fault and slope
systems encompassed
in its arc will feel the added weight of sea level rise caused by human warming.
Instead, natural variations
in the climate
system and other external forcing factors (such as
volcanic eruptions) will likely cause the rate of Arctic sea ice change to vary considerably from decade to decade, and perhaps even temporarily switch from negative (sea ice loss) to positive (sea ice growth).
Stenchikov et al. (2006) showed that models have difficulty
in capturing the regional response of the climate
system (ao) to
Volcanic singularities specifically the temperature regime
in eurasia
in the Giss model, or
in retrodiction ie the Krakatoa problem why was it so warm, thus there is no uniqueness theorem for
volcanics.
