The sun is the primary temperature driver and warms the oceans in which huge quantities of heat are stored and released into the atmosphere over long multi decadal periods of time usually operating via the oscillations in each ocean. (newclimatemodel.com)
The first 2 trendlines are sub-decadal and should be ignored (although they fit my hypothesis), but the following 3 are decadal periods with distinct trends. (skepticalscience.com)
Because the long - term warming trends are highly significant relative to our estimates of the magnitude of natural variability, the current decadal period of stable global mean temperature does nothing to alter a fundamental conclusion from the AR4: warming has unequivocally been observed and documented.
