“Science is the belief in the ignorance of
experts” — Richard Feynman
Contrary to what one might have guessed from Part
One of Climate Change and the Great Manure Crisis of 1894 yesterday,
I'm not suggesting that climate change isn't happening, because of course it
is, or that it isn't important, because of course it is. Nor am I arguing that
humans don't have some degree of impact on it, because I simply don't know, and
neither I nor almost anyone engaged in this public “debate” is equipped to
carry on that argument.
Having a science degree no more confers
climate expertise, than having an arts background means one has expertise in
impressionist art. What I am concerned
about is the level of hysteria afoot out there over something that almost no
one understands.
I daresay 999,999 of 1,000,000 people out
there don't understand the climate equation either, despite ridiculous and
long-discredited claims involving “97% of scientists agree” - see
here for an explanation, and
here, and
here.
Those scientists who actually DO have
training in global weather dynamics readily admit that just because a
CO2-engendered greenhouse effect can be created in a closed system, within a
laboratory, it doesn't mean that the same thing will happen in the multivariate
environment of the global climate system, subject to literally trillions upon
trillions of additional variables ... half of which they don't understand and
some of which they don't even know exist.
The theory of computational complexity deals
head-on with this problem: it simply posits that after a certain level of
complexity, even the best science becomes a guess because the data are too
voluminous, the processing steps are infinite, all the computational power in
the world is insufficient, or all three. In the case of climate science,
it's all three. The global climate system is simply too big, with too many
variables, to make any realistic conclusions possible.
Even the IPCC has taken to using the
terminology of “probabilities” in its lay commentary to its annual reports,
although it certainly hasn't lost its enthusiasm for issuing dire predictions.
A majority of scientists involved with
climate science may believe that increased CO2 is contributing to a greater or
lesser degree to climate change, but it is not a testable thesis, which makes
that supposition a hypothesis, far below the status of theory. As Sanjeev
Sabhlok points out, science is the act of questioning and not of consensus,
and any viable scientific theory must necessarily make accurate predictions
both backwards and forwards.
Yet climate models have been consistently
wrong, and numerous deadlines and 10 year periods have passed without their
dire predictions having come true: here, here,
and
here.
Contrary to popular belief, for example, the
UN Climate Panel found that hurricanes haven’t in fact increased, and there is
very little evidence that they will increase in the future ... “Current
datasets indicate no significant observed trends in global tropical cyclone
frequency over the past century.”
Later, last year, the finding was reiterated
in the 2018 Special Report on Global Warming of 1.5°C ... “Numerous studies towards and beyond AR5 have reported a decreasing
trend in the global number of tropical cyclones and/or the globally accumulated
cyclonic energy … there is consequently low confidence in the larger number of
studies reporting increasing trends in the global number of very intense
cyclones.”
Regarding floods, the IPCC’s Special Report
concluded: “There is low confidence due to limited evidence, however, that
anthropogenic climate change has affected the frequency and the magnitude of
floods.”
And yet it is received wisdom in the public
domain that climate disasters will not only become more frequent, but more
intense. Why?
None of the above is to suggest that what
Gramcsi would have called the “hegemonic belief” over the larger beliefs over
anthropogenic climate change are necessarily wrong, but simply to point out
that “science” isn't a monolithic block of unquestionable certainty, even IF
the claim of “consensus” were true. But it does explain why the discussions
surrounding climate change have more of the hallmarks of a religious movement
than a scientific process.
If a claim cannot be proven through the
rationalist tradition (science), it must be proven through the agency of faith.
In fact, these claims of consensual certainty
are not an appeal to actual science so much as an appeal to authority on the
cheap, much as an appeal to a Holy Book is an appeal to the authority of an
unquestionable God.
Stay tuned ... Part Three of Climate Change
and the Great Horse Manure Crisis of 1894 continues tomorrow.
— Scott Anderson comments and analysis from a
bluntly conservative point of view.
Nice piece. A thoughtful look at how and why there is no consensus on such a complex issue. But I do disagree with the claim early on that there is so much information to digest that no one should be expected to know it all, or to claim to have it all figured out - because that IS possible.
ReplyDeleteThanks to the Internet and Google searching anyone who wants to can find links to posts that discuss almost any angle you can think of on almost every issue you can think of, certainly including one of the most-debated issues in human history: is mankind damaging Earth's climate and if so is that or is that not part of a plan by an entity we call God?
To put it simply, Is God controlling the environment, climate and human beings in it? Or, are human beings damaging God's created environment to His great annoyance? Or are planet Earth and humanity merely an evolution from random selection and therefore nothing really matters?
The "science" we have available now suggest that humans are affecting the planet's environment but it's really not likely that will lead to catastrophic climate changes able to exterminate all life - but on the other hand mankind's nuclear weapons could do that! And it was predicted in The Bible about 3,000 and 2,000 years ago.
In other words, as big as the climate issue is it's still only a small part of the cosmos, and how it all fits together and works or will soon cease to work is a question that remains to be answered.
