In physics,
for example, the Heisenberg
Uncertainty Principle or principle of indeterminacy has been interpreted in three ways: 1) that the «laws of nature» are deterministic, and that any uncertainty is due to human ignorance, which in due time will be resolved by science (Einstein), 2) uncertainty can be always explained by present experimental limitations (Neils Bohr), and 3) indeterminacy is an objective characteristic of reality Werner H

In quantum physics, the Heisenberg
uncertainty principle states that one can not assign, with full precision, values
for certain pairs of observable variables, including the position and momentum, of a single particle at the same time even in theory.
Now Stephanie Wehner and Esther Hänggi at the National University of Singapore's Centre
for Quantum Technology have taken a new tack, recasting the
uncertainty principle in the language of information theory.
Yet Heisenberg's
uncertainty principle dictated that precise values
for certain pairs of variables, such as position and momentum, could never be known simultaneously.

for a brief period of time — a quirk made possible by Heisenberg's
uncertainty principle.
His new result made use of a pillar of quantum theory called the
uncertainty principle, according to which the detailed properties of an object — its position or velocity,
for example — can never be completely pinned down.

for the policy framework to be politically feasible.
In fact, most
uncertainties in the alarmist pseudo-science are internal contradictions and consequences of its shoddy practices: cherry picking data, making conclusions based on statistically insignificant observations, declaring trends based on variations that are within error margins, relying on computer models that contradict
principles of the information theory, forging forecasts
for unreasonably long time periods, etc..
Increased
uncertainty provides a greater probability of occurrence of the catastrophe, strengthening the case
for action under the precautionary
principle
That is, under the weak precautionary
principle,
uncertainty does NOT make the case stronger
for action, whereby the under the strong precautionary
principle,
uncertainty arguably strengthens the case
for action.
Clean up the IPCC consensus process and clear up all the many
uncertainties first before clamoring
for mitigating action based on the «precautionary
principle».
Concerning the
uncertainty of assessments made by IPCC, already in The Environment Conference Rio de Janeiro 1992 there was agreed a
principle according to which» lack of full scientific certainty shall not be used as a reason
for postponing cost - effective measures to prevent environmental degradation».
So it becomes necessary to downplay the high level of «
uncertainty» in order to justify the need
for «urgent action», cloaking it all as the «precautionary
principle».
On the other hand, if the requirement is a validation of the underlying «peak production»
principle (i.e. production from large resources maturing and going into decline, and not being sufficiently offset by newer smaller resources to maintain overall growth), and if we can accept some
uncertainty around the date and height of the peak, then we have many examples of regions and countries in which exactly this process has occurred
for oil and other resources.
If this is true, the strong precautionary
principle is a hard sell as the preferred option
for decision making under deep
uncertainty.
But a point you raised gnawed at me, and I tentatively reached a result that is an argument
for your point of view: if you start with our atmospheric pressure at ground level, the difference in kinetic energy Velasco et al. specify

uncertainty less than a second even in
principle unless the gas - column width is less than something on the order of 100 nitrogen - molecule diameters across.

Adapting core
principles of risk assessment to climate: To date, the approach of climate change assessments has primarily been rooted in communicating relative scientific certainty and
uncertainty around anticipated changes in the physical climate system, along with some basic biophysical impacts that would seem to be generally implied by those climate changes: based,
for example, on general understanding of associations such as those between impacts and weather extremes.
Furthermore, the report discusses the
principle sources of
uncertainty for the indicators and notes how monitoring and scenario development can improve our understanding of climate change, its impacts and related vulnerabilities.
Starting from two different decision frameworks (precautionary
principle versus robust decision making) and assumptions about the nature of the
uncertainty (PDF versus possibility distribution) results in opposite conclusions regarding whether
uncertainty weakens or strengthens the case
for action.

For me, personally, as a general
principle it is important to try to quantify
uncertainty when discussing scientific conclusions.
The precautionary
principle, which calls
for extra prudence in areas of scientific
uncertainty, also applies.
We have too many people who want to re-define or even by - pass this process completely, citing the precautionary
principle as a justification
for a sense of urgency to act now despite all the
uncertainty that still exists.
Therefore they have decided to support the application of the precautionary
principle by stating the
uncertainties as less than any objective systematic analysis can support and using subjective judgments as a more reliable basis
for quantitative conclusions than they really are.
But I believe in
principle it has to be done this way, specifying tolerances
for the
uncertainty of the input parameters and then working out the spread of the variations.
On further reflection I believe that in
principle it doesn't matter how you measure
uncertainty (I guess this is what you called bias
for individual runs), especially if the aforementioned kind of baseline is unknown.
