in three subjects — computation, mathematics and physics (and I mean this literally — it is listed twice in this page devoted primarily to computational physics grand challenges, Navier - Stokes is one of the grand challenges in mathematics with a substantial prize, and both classical and quantum chaos, self - organizing phenomena and complexity in general are grand challenges in physics (all present in the single problem of understanding the climate well enough to compute
meaningful predictions of future climate)-- it seems both unlikely that this science will be «settled» soon, nor is it at all unreasonable that it is not settled at this point in time.
She chronicles all of these issues and more through the knowledge of what's come before and
meaningful predictions of what might well lay ahead.
This field, it is widely believed, has advanced sufficiently to permit
meaningful predictions of the impact of population changes on the social and economic development of both rich and poor societies.
Of course, you know this because you believe it, but please address the point about how can one even start to make
any meaningful prediction of the future without a model and without models policy making and preparation is a hopeless task.

The holy grail for those who want to preserve the idea
of free will is a rigorous articulation
of the proposition that mere
prediction does not imply the lack
of freedom (or, perhaps, a lack
of the
meaningful kind
of freedom, since we all mean different things when we talk about «free will» anyway).
In addition, because
of recent improvements in the accuracy
of theoretical
predictions based on large - scale ab initio quantum mechanical calculations,
meaningful comparisons between theoretical and experimental findings have become possible.
It turned out, adding those variables did not improve the accuracy
of their
predictions in a statistically
meaningful way, compared to their
predictions based on fitness alone.
With News Feed ranking, Facebook's algorithms look at available signals and make a set
of predictions that help us to estimate how
meaningful we think
Throughout this edition the authors offer a variety
of perspectives on student voice, offering optimistic
predictions, detailed accounts, thoughtful reflections, and cautionary criticisms that strengthen the argument for
meaningful student involvement.
Of course, these results can not be directly extrapolated to the real climate system, but they do disprove the common but misguided claim that chaotic weather necessarily prevents
meaningful climate
prediction.
I also believe that the
prediction of future ice states in the Arctic is not possible in any
meaningful sense.
My friend, Climate Science is not a science since it has no precise numerical variables, no laws, and statistics are not applicable because there is no physically
meaningful time intervals over which to take averages and no periodicity The system is not stationary — meaning that the earth and its atmosphere and the sun, and the molten interior and the cosmic radiation present a constantly changing environment far beyond the capabilities
of prediction.
This convergence
of El Nino and solar effects has unfortunately confused many and is exactly the reason that temperature changes over a decade are not very
meaningful in climate
prediction.
In other words, even if you've got a whole series
of cycles to go on, without a mechanism you can't make ANY
meaningful predictions.
But you work with something that nobody can explain in physical terms and that requires so much time that any
meaningful prediction might take hundreds
of years to happen.
What is known
of natural climatic variations
of the past 100 million years provides invaluable insights into projected greenhouse warming, and the only
meaningful tests
of some
of the modeled
predictions.
If someone had wanted to produce a
prediction based on multiple models that matched short - term trend lines, one would have had to somehow aggregate the short term trend lines
of the models in a
meaningful way, which is pretty much the opposite
of what one gets by taking the mean
of the models.
They carefully state that this is not meant as a firm
prediction, «The exact timing
of these events is not
meaningful, given the great aggregation and many uncertainties in the model.
Predictions that the oil industry will stabilise and show
meaningful signs
of recovery towards the latter half
of the year are bringing these opportunities forward.
But instead
of relying solely on matching cases, the tool now examines hundreds
of Canadian wrongful dismissal cases where the Bardal Factors have been considered to statistically derive a
meaningful prediction and forecasted range
of probable results.
These criteria required evidence
of test — retest or inter-rater reliability and / or basic validation data, including comparison with existing «gold standard» instruments, factor analytic findings that fit with previously developed theory or other instruments or
prediction of meaningful correlates or outcomes.
