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.

Those more reasonable valuations could be achieved by a big stock market crash or a sustained malaise similar

Furthermore, each candidate had

decade or during the
timeframe measured (note on the annualized performance column that several of the companies did not possess a full 11 - year track record).
When you extend the

to roughly 2
decades, whereas the second part was schematic and therefore anhistorical.
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).
(4) For the
timeframe covering the period between 2007 and 2035, GMST could experience a rising temperature trend of anywhere from +0.03 per
decade on up
to +0.4 C per
decade, while still remaining within the scope of past historical precedents documented in the Central England Temperature record for similar periods of time.
Evidence also suggests the earths temperature changed extremely rapidly following this release (on the order of a
decade) well within the
timeframe Methane breaks down
to CO2.
The main conclusions are: 1) The linear warming trend during 1973 - 2012 is greatest in USHCN (+0.245 C /
decade), followed by CRUTem3 (+0.198 C /
decade), then my ISH population density adjusted temperatures (PDAT) as a distant third (+0.013 C /
decade) 2) Virtually all of the USHCN warming since 1973 appears
to be the result of adjustments NOAA has made
to the data, mainly in the 1995 - 97
timeframe.
Chapter 6 highlights the fact that there are now a large number of different paleoclimate studies which all lead
to the same key conclusion that northern hemisphere mean temperatures in recent
decades are likely unprecedented in at least a millennial
timeframe.
Natural temperature influences have had a very slight cooling effect, and natural internal variability appears
to have had a fairly significant cooling effect over the past
decade, but little temperature influence over longer
timeframes.
In normal impact modeling the discount rate serves
to limit the
timeframe to a few
decades, but in SCC this does not happen.

to draw any definitive conclusions about changes in the long - term trend.
I think that, given how steadily it has been warming since 1980 (about 0.3 C per
decade for the average land area, see below), a forward projection would be a good central estimate around which
to add the uncertainty that partly includes what emissions will do in that
timeframe.
Anything before that
timeframe is less important
