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.

... we strongly support Delworth and Knutson's (2000) contention that this high - latitude warming event represents primarily natural variability within the climate system, rather than being caused primarily by external forcings, whether solar forcing alone (Thejll and Lassen, 2000) or a combination of increasing solar irradiance, increasing anthropogenic trace gases, and decreasing volcanic aerosols.

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.

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.
