rate of melting of glaciers, snow and ice it lands upon, which can lead to less reflectivity,

means it will not be a smooth
warming.
We still don't expect each year to be
warmer than the last due to the intrinsic variability («weather») in global
mean temperature (around 0.1 to 0.2 °C), but at the current
rate of global
warming (~ 0.17 °C / decade), new records can be expected relatively frequently.
One solution which has different assumptions than what is used to define the HadCRUT4 global values, would be to calculate the zonal

warms at the same
rate as the local zonal average as opposed to the global
means.
It is conceivable that aerosol effects (which includes «smoke») could also affect the lapse
rate, but the aerosols tend to
warm where they are located and depending on the composition, cool below — this gives an impact that — if it was a large factor in the tropical
mean — would produce changes even larger than predicted from the moist adiabatic theory.
Much of the paleoclimate community has confused the correct inference that water properties changed (got fresher or
warmer for example) with the conclusion that
means that the flow
rate had to change.
What this
means is that the overall
rate of absorption of CO2 by the oceans is a complex function of numerous processes — biological, chemical and physical — whose individual contributions are still a matter of active scientific research (and which are certainly changing as the planet
warms).
«Since the AR4, there is some new limited direct evidence for an anthropogenic influence on extreme precipitation, including a formal detection and attribution study and indirect evidence that extreme precipitation would be expected to have increased given the evidence of anthropogenic influence on various aspects of the global hydrological cycle and high confidence that the intensity of extreme precipitation events will increase with
warming, at a
rate well exceeding that of the
mean precipitation..

DK12 used ocean heat content (OHC) data for the upper 700 meters of oceans to draw three main conclusions: 1) that the
rate of OHC increase has slowed in recent years (the very short timeframe of 2002 to 2008), 2) that this is evidence for periods of «climate shifts», and 3) that the recent OHC data indicate that the net climate feedback is negative, which would
mean that climate sensitivity (the total amount of global
warming in response to a doubling of atmospheric CO2 levels, including feedbacks) is low.
Since the
mean radiative forcing progression in RCP 8.5 is likely steeper than the radiative forcing progression of the recent past, this finding can not be used to suggest that models are overestimating the response to forcings and it can not be used to infer anything about future
rates of
warming.

rates of stratospheric cooling and tropospheric
warming relative to global
means.
The lack of a statistically significant
warming trend in GMST does not
mean that the planet isn't
warming, firstly because GMST doesn't include the
warming of the oceans (see many posts on ocean heat content) and secondly because a lack of a statistically significant
warming trend doesn't
mean that it isn't
warming, just that it isn't
warming at a sufficiently high
rate to rule out the possibility of there being no
warming over that period.
What matters is not the
warming rate since the mid-19th century but the fact that ice core data reveal the existence of a quasi-millenarian (natural) oscillation, that well correlates with observed (

The prediction of this is obvious:
warming will continue at the same
rate it's done since 1970, which
means the plateau will not last.
