Human induced trend has two components, namely (a) greenhouse effect [this includes global and local / regional component] and (b) non-greenhouse effect [local / regional component]-- according to IPCC (a) is more than half of global average temperature anomaly wherein it also includes component of
volcanic activities, etc that comes under greenhouse effect; and (b) contribution is less than half — ecological changes component but this is biased positive side
by urban -
heat - island effect component as the met network are concentrated in urban areas and rural - cold - island effect is biased negative side as the met stations are sparsely distributed though rural area is more than double to urban area.
In fact, we know that major
heat releases such as
volcanic eruptions are,
by definition, not steady.

volcanic action or at least
heat from below.

The IPCC has attributed the pause to natural climate fluctuations caused
by volcanic eruptions, changes in solar intensity, and the movement of
heat through the ocean.
This is part way into a question I asked at RC... QUESTION: Do these experiments take into account any
heat added to the water
by underwater
volcanic activity or fumeroles or even fresh water runoff from rain?
In short high altitude areas like the Himalayas, Andes, and the Rockies and a few
volcanic peaks are «short circuits» in the troposphere, where energy absorbed
by the ground from solar
heating can be almost immediately radiated back to deep space directly from the ground.
The world's climate is way too complex... with way too many significant global and regional variables (e.g., solar,
volcanic and geologic activity, variations in the strength and path of the jet stream and major ocean currents, the seasons created
by the tilt of the earth, and the concentration of water vapor in the atmosphere, which
by the way is many times more effective at holding
heat near the surface of the earth than is carbon dioxide, a non-toxic, trace gas that all plant life must have to survive, and that produce the oxygen that WE need to survive) to consider for any so - called climate model to generate a reliable and reproducible predictive model.
Convective patterns driven
by heat transport in the interior of the Earth push one crustal plate under another (subduction) and the friction
heats up the magma necessary for
volcanic action — which in turn releases CO2 into the atmosphere.
Some scientists have also attributed warmer air temperatures in the North Atlantic region to the delivery of warmer seawater (
heated by solar radiation unimpeded
by volcanic aerosols)
by the Gulf Stream and other currents.

Possible explanations advanced for the slowdown include the effect of small
volcanic eruptions, the absorption of extra
heat by the oceanic depths and the juxtaposition of two natural ocean cycles.
This climate modeling capability made it possible to perform a real - time climate change prediction (verified
by subsequent observations) of the global cooling and stratospheric
heating (and return to normal) following to the 1991 Pinatubo
volcanic eruption.
To that you answer if the temperature ever starts to rise, due to say
volcanic heat, or upwelling to water's surface, the
heat is immediately removed
by the power of evaporation as infrared - resonant gases chug
heat straight up through the atmospheric mix to belch it out radiatively at higher altitude; while simultaneously dragging other, non-infrared resonant gases upward with them, to also dump THEIR
heat radiatively, from a higher position than they would have, had the refrigerative cycle not taken place.
The ability of models to simulate ocean
heat uptake, including variations imposed

Forster et al. (2007) described four mechanisms
by which
volcanic forcing influences climate: RF due to aerosol — radiation interaction; differential (vertical or horizontal)
heating, producing gradients and changes in circulation; interactions with other modes of circulation, such as El Niño - Southern Oscillation (ENSO); and ozone depletion with its effects on stratospheric
heating, which depends on anthropogenic chlorine (stratospheric ozone would increase with a
volcanic eruption under low - chlorine conditions).
