It is also important to note that the models are not designed to project
climate on a decadal basis, but on a centennial basis, where the effects of internal variability can more reasonably be expected to average out.
Variability of
our climate on a decadal basis is considerable and is even greater on an annual basis.

Based on what we've found, it is possible that sea - level rise over
decadal time scales will be a key storyline in future
climate predictions,» he said.
The big takeaway from this study: While there is uncertainty in projections for changes in the
climate indices reviewed here (especially El Niño and La Niña), this study serves to alert us to the fact that the
climate impacts that our local coastal communities face are
based in large part
on changes that occur
on both a large, global scale and over the long,
decadal term.
Back around 2007/8, two high - profile papers claimed to produce, for the first time, skilful predictions of
decadal climate change,
based on new techniques of ocean state initialization in
climate models.

on a region by region
basis.
Based on the results, we suggest that human footprint
on soil greenhouse gases fluxes is comparable to the effect of
climate change at an annual to
decadal timescales.
The model is actually
based on ocean and atmospheric indices — in this case the El Niño Southern Oscillation, the Pacific
Decadal Oscillation, the North Atlantic Oscillation and the North Pacific Oscillation — and can be thought of as chaotic oscillators that capture the major modes of
climate variability.
As you can see in the first graph sudden and noticeable

climate changes frequently when calculated
on an annual and
decadal basis, in fact virtually no decade is like its predecessor or successor.
> Those more
climate concerned
based «projections»
on decadal models and support their «results» all the time.
Perhaps even more remarkable is that despite these
climate oscillations, temperatures
on a
decadal basis remain bounded within the tight limits noted of -1.3 to 0.8 C so giving a remarkable constancy of around 2 degrees C throughout the near 500 year record.
Some researchers took the news calmly: in a global
climate that varied daily, seasonally, annually and
on a
decadal basis, there was no guarantee of an inexorably steady climb in global averages, they said.
Although our results are
based on an idealized modeling framework that captures only naturally occurring
climate variations, they clearly suggest that
decadal climate predictions for soil hydrological conditions are feasible and may become beneficial for forestry, water management, and agriculture.
The CET data for the period indicate a distinct
climate shift of some 0.35 degrees centigrade
on a 50 year
basis, but rather more
on a
decadal basis, so that well documented era can usefully be our benchmark for temperature comparisons, whilst demonstrating the usefulness of a
decadal time scale in determining a change in the
climate that is «noticeable» and has an impact
on humans and nature.
The results of the DCPP are a contribution to the 6th Coupled Model Intercomparison Project (CMIP6), to the WCRP Grand Challenge
on Near Term
Climate Prediction (NTCP), potentially to the Sixth Assessment Report of the Intergovernmental Panel
on Climate Change (IPCC), to the Global Framework for
Climate Services (GFCS), and as one of the
bases for the development of a WMO Commission for Basic Systems (CBS) Global
Decadal Climate Outlook (GDCO) in support of applications.
Based on the understanding of both the physical processes that control key
climate feedbacks (see Section 8.6.3), and also the origin of inter-model differences in the simulation of feedbacks (see Section 8.6.2), the following
climate characteristics appear to be particularly important: (i) for the water vapour and lapse rate feedbacks, the response of upper - tropospheric RH and lapse rate to interannual or
decadal changes in
climate; (ii) for cloud feedbacks, the response of boundary - layer clouds and anvil clouds to a change in surface or atmospheric conditions and the change in cloud radiative properties associated with a change in extratropical synoptic weather systems; (iii) for snow albedo feedbacks, the relationship between surface air temperature and snow melt over northern land areas during spring and (iv) for sea ice feedbacks, the simulation of sea ice thickness.
