This 0.06 °C accounts for approximately 12 % of the warming
trend over the timeframe in question.
Over the continental USA (CONUS), satellites show a 0.24 °C per decade warming
trend over the timeframe in question.

The market still holds a strong bullish
trend probability
over in the weekly and monthly
timeframe.
internal / natural variability
over a long enough
timeframe will not alter the long term
trend of the temperature record (as we are always reminded) but in this relatively short term analysis it did especially for the last decade
At the risk of oversimplifying, the effects of groundwater storage can be differentiated between shallow - aquifer effects that modulate global sea level on year to year and decade to decade
timeframes, versus deep aquifer effects that modulate sea level
trends over centuries and millennia.
Christy is correct to note that the model average warming
trend (0.23 °C / decade for 1978 - 2011) is a bit higher than observations (0.17 °C / decade
over the same
timeframe), but that is because
over the past decade virtually every natural influence on global temperatures has acted in the cooling direction (i.e. an extended solar minimum, rising aerosols emissions, and increased heat storage in the deep oceans).
The last decade hasn't been cooling btw, though a slower upward
trend or even standstill in the
trend (of one would deem it meaningful
over such a short
timeframe) is of course helped by the dampening effect of natural factors having a cooling effect, offsetting some of the warming effect of GHG.
However, as Dikran noted in response, it's entirely possible that
over such a short
timeframe, short - term noise such as ENSO and solar cycles may have masked the continuing long - term global warming
trend.
Winter precipitation (mean and extreme) variability and
trends along the south coast and interior of Alaska appear to be closely related to variations in the PNA pattern
over this
timeframe, while El Nino / Southern Oscillation (ENSO) influences, through the Nino3 index, appear to be significant along the south coast alone.
As SkS has discussed at length with Dr. Pielke Sr.,
over short
timeframes on the order of a decade, there is too much noise in the data to draw any definitive conclusions about changes in the long - term
trend.
Now, where GG's graph does have shortcomings is that it does not account for the
timeframe of adjustments, but rather it looks at the net effect on the
trend over the full period of measurements for each individual station.
As we have recently discussed, although we can't say for certain statistically, it's likely that the global surface temperature warming
trend has slowed
over the past decade, because virtually all short - term temperature impacts have been in the cooling direction
over that
timeframe.
As such, it is an invaluable tool for quickly comparing temperature
trends over varying
timeframes.
