«Skeptics» are approaching
uncertainty in science with a massive bias.
Not exact matches
Such a notion as emergence, for example, which is closely allied
with the principle of indeterminacy and
uncertainty and which was later to develop
in physics, actually assumed more credence
in physics before it took root
in biology and psychology; yet it has more significant implications for the data of the organic and social
sciences than for physics.
That representation matches the public discourse around global warming,
in which previous studies have shown that media characterize climate change as unsettled
science with high levels of scientific
uncertainty.
Generally, this is not a good thing when embarking on a career
in science, because even the most successful researchers can find their careers fraught
with uncertainty.

in the biological
sciences about what they are doing to assess whether it is the specific area of specialization that is leading to your difficulty and level of
uncertainty.
We've reached a point now
in the interdisciplinary growth of our
science where we've got climate scientists, who understand the physics of climate and how that translates to
uncertainties, working hand
in hand
with economists who will run the projected impacts through a cost - benefit analysis.
«The model we developed and applied couples biospheric feedbacks from oceans, atmosphere, and land
with human activities, such as fossil fuel emissions, agriculture, and land use, which eliminates important sources of
uncertainty from projected climate outcomes,» said Thornton, leader of the Terrestrial Systems Modeling group
in ORNL's Environmental Sciences Division and deputy director of ORNL's Climate Change
Science Institute.
«There are so many variables that will affect the future of forests
in northern Minnesota, forest managers will probably always have to deal

with the Northern Institute for Applied Climate
Science (NIACS).
The first installment

I think this is a tricky communication problem that partly has to do
with the common perception of «
science» as something that always provides solid facts and is characterized by little
uncertainty (probably a product of memorizing scientific facts
in high school texts).
The most significant
uncertainties do * not * lie
with the
science, but
in knowing the consequences of various policy options.
I recently researched causes of subsidence
in Bangladesh (Brown and Nicholls 2015) and struggled

uncertainties, data errors, and
in some cases, poor
science when recording rates of subsidence.
I've written
in the past about other issues related to setting a numerical limit for climate dangers given both the enduring

science pointing to a gradient of risks rising
with temperature.
* Average citizens «understand» (recognize)

The review, which is being published
in the journal
Science on Friday, concludes that the human - driven buildup of carbon dioxide under way now appears to be far outpacing past natural events, meaning that, for ocean chemistry particularly, the biological implications are potentially enormous — and laden
with the kind of
uncertainty that is hard to see as a source of comfort.
Today and Wednesday a group of authors from across the different working groups — examining the basics of climate
science, the impacts of warming and options for policy responses — are meeting at Jasper Ridge
in northern California to come up
with an approach for «consistent evaluation of
uncertainties and risks.»
Koenig's careful description of the
science and the
uncertainty about what the future holds prompted a public spanking from the Center for American Progress climate blogger Joe Romm, who charged her
with «scientific reticence» — alluding to NASA scientist James Hansen's paper criticizing sea - level researchers for being overly cautious
in 2007 conclusions about the possible rate of sea rise
in this century.

So the issue that montford raises, and that i have raised
in my posts, are general issues, about the integrity of
science, how to avoid conflicts, how to deal
with mistakes, how
science should be conducted when there are alot
uncertainties and the field is immature, when the situation is politicized, etc..
In the interview,
with Andy Balaskovitz, I described the value of having a public more attuned to how
science works — that new knowledge is what's left over after peers chew on each others» data and analysis, and that argument and
uncertainty are normal, that
science is a journey, not a set of facts:
I'm not a cloud expert, and I may be describing this particular
uncertainty inaccurately, but I use this as one example, and (unless this aspect of the
science has changed
in recent months) I believe that one aspect of
uncertainty has to do
with these clouds and their ultimate net effect as the atmosphere warms.
With Carson's approach to conveying risk, they write, she appears to have created «a bridge across the is — ought divide
in science - related policy making, using the
uncertainty topos to invite the public to participate by supplying fears and values that would warrant proposals for limiting pesticide use.»
The climate talks
in Copenhagen this month present layers of complexity, shifting alliances among nations, hidden agendas and
science laced
with persistent
uncertainties.
These revisions are one example of a strategy we saw Carson use consistently: Add
uncertainty at the level of ignorance to destabilize the
science, then articulate the harms, hazards, or consequences behind our current actions, and drive it home
with a visceral image of risk (which she does
in this example through images of liver damage, the accumulation of DDT
in milk and butter, and the ability of toxic chemicals to pass to breast - fed human infants, and to a fetus
in utero).
Anyone notice the huge contradiction between an author (Curry) that declares that all of climate
science is bound by
uncertainty, yet
in Curry's own research, the physics is stated by assertion,
with zero
uncertainty implied?
I have no problem
with focusing the debate on the current
uncertainties in the
science — which a reputable scientist that Curry claims to be would do — but this tripe shows a colour of anti-
science denialism that is truly shameful
I think part of this comes from scientists, both those working
in that specific area of climate
science and particularly those from outside that area, speaking not as scientists
with their inherent tendency not to claim something conclusive without a good deal of statistically tested certainty, but speaking as someone who has been imposed upon or volunteered to give a scientific best guess without bothering the public
with the details of
uncertainties.
I'd say «that's the way it is» and live
with it happily on most
science controversies (plate tectonics, big bang / steady state, etc) because they don't have a massive impact on our daily lives and so we can easily wait for the
science to work itself out, but on issues that look to have massive impacts on our daily lives (fat vs. carbs
in diet, CAGW) there must be a better way of dealing
with the
uncertainties before we throw all our eggs into a single basket.
Their tactics and fallacies include ignoring or distorting mainstream scientific results, cherry - picking data and falsely generalizing, bringing up irrelevant red - herring arguments, demanding unachievable «precision» from mainstream
science with the motif «if you don't understand this detail you don't understand anything», overemphasizing and mischaracterizing
uncertainties in mainstream
science, engaging
in polemics and prosecutorial - lawyer Swift - Boat - like attacks on
science - and lately even scientists, attacking the usual scientific process, misrepresenting legitimate scientific debate as «no consensus», and overemphasizing details of little significance.
Meanwhile, the good news (if further research bears it out) that the world's warming has been slowed, at least for a few years, needs to be leavened
with the realisation, yet again, that there are significant
uncertainties in science's understanding of the climate — and thus unquantifiable risks ahead.
Three years ago Smith wrote
in the Washington Post, «Contrary to the claims of those who want to strictly regulate carbon dioxide emissions and increase the cost of energy for all Americans, there is a great amount of
uncertainty associated
with climate
science.»
With a climate sensitivity of roughly 1 from «settled» CO2
science, some evidence for natural shifts
in global climate of 0.5 - 1.0 degK, and a fair amount of
uncertainty in feedbacks, my Italian flag (based on physics) will probably be mostly white if climate sensitivity is > 2.5.
Given that much of the
science backing the consensus view is not
in contention, and given that as we saw
in the last entry
in this series that there is an ethical need to be very careful
in talking about the
uncertainties associated
with climate
science, a PR firm led strategy that emphasizes
uncertainty without regard to how much of the
science is settled is extraordinarily unethical.
By looking at these different areas he will dig into the difficult questions of how to deal
with uncertainty in science, the communication of this
uncertainty, and the difficulties when
science meets policy and the media.
Judith, I'd contend that there is a greater difference between the scientific consensus position and that of
science scepticism
with regard to
uncertainties, even if there is little to distinguish them
in the
science.
It is not merely that there are
uncertainties, as always
with science, but that the
uncertainties in climate
science are of large enough magnitude that they can not be asserted to be too small to matter.
Some of that 97 per cent are genuinely grappling
with the
uncertainties of climate
science, usually
in very focused, specific areas.
The situation
with your unsubstantiated certainty w / r / t economics does not necessarily generalize to your approach to climate
science, but your failure to acknowledge an obvious case of being overly certain does suggest, I'd say strongly, a systematic problem
in your approach to
uncertainty.
With the exception of the 1991 ICE memos — which I will get to shortly — the next most favored leaked memo phrase is the one out of the 1998 API documents, «Victory will be achieved when... Average citizens «understand» (recognize)
uncertainties in climate
science...» That isn't a sinister industry directive, it is a basic truism.
We have the «scientist» who understands the questions,
uncertainties and doubts that are inherent
in Climate
Science with the scientific ethos of full disclosure of all those, and the «human being» who for the good of the planet must address the non scientific audience
with dramatic, simplified, scary and non realistic scenarios.
Many physical modelers, and especially climate modelers, seems to think that as long as their models are «
science - based» then there is no need to account for
uncertainty in their outputs, notwithstanding that the model parameters are tuned
with data, and that aspects of these models are likely to be ill posed (highly sensitive to small perturbations
in the values assigned to parameters).
But then came Climategate plus the revelation of IPCC screw - ups and,
with them, the growing suspicion that the «
science» had been «cooked» — or, at least, that IPCC had understated
uncertainties in the attribution of climate change as well as
in the projections for the future.
However it reminds me of a thought I had that it might be a good idea to have a guest article on this blog that deals
with the ozone layer issue,
uncertainties in the
science, ramifications of the policies that were implemented, and implications for addressing the possibility of AGW — or not.
No data
in science is ever exact — all of it comes
with uncertainties, the possibility of bias, and more.
How do you reconcile very large
uncertainty re climate
science in general
with apparently very limited
uncertainty re ECS and impacts (you seem very sure both are small)?
This to me is a very pertinent conclusion as previous studies were lambasted at WUWT for showing those losses (and subsequently responded to by me over at Skeptical
science) http://www.skepticalscience.com/Part-One-Why-do-glaciers-lose-ice.html http://www.skepticalscience.com/Part-2-How-do-we-measure-Antarctic-ice-changes.html http://www.skepticalscience.com/Part-Three-Response-to-Goddard.html So even
with the
uncertainties lowered it is still clear that the submarine portions of EAIS are losing more ice than the center part is gaining
in snowfall.
Conclusion FOMD and his Jefferson - loving / Berry - loving [milk]- brethren join
with Steven Mosher and James Hansen
in celebrating rational
science - respecting discourse regarding climate -
