The cost and futility of trading hot air
Why carbon
‘cap-and-trade’ is an immoral non-solution to a
non-problem
The “Environmental Defence Fund” (EDF) has
circulated a “Report ” that says the cost of controlling the “pollution that
causes ‘global warming’” is “only pennies a day … almost too small to measure.”
The conclusions, summarized by EDF, are –
• “We cannot afford to wait.
Further delay will greatly increase the costs of making necessary emissions cuts
and will risk locking in irreversible climate change.” The “Report” says: “The
scientific consensus is clear: Global ‘warming’ is real, and it is already
happening. While nobody can be certain about the exact timing or location of its
consequences, the possible severity of those consequences is becoming
increasingly clear. Allowing greenhouse gas emissions to increase unchecked is
an invitation to catastrophe. The potential consequences of warming include
widespread famine, triggered by extreme drought in the major grain-producing
areas of the world; the wholesale disappearance of the world's coral reefs; and
sea levels rising by several meters over the course of a few centuries.” The
“Report” concludes that we must act now to avoid “catastrophic climate
change”.
• “We can afford an aggressive cap-and-trade policy to tackle
‘global warming’. The cost to the economy will be minimal -- less than one
percent of U.S. gross domestic product in 2030. The “Report” says that the US
economy will grow to “$26 trillion by 2030, but, with a cap on the greenhouse
gas emissions that cause ‘global warming’, the economy will reach the same level
two to seven months later. It adds that job losses would be minimal; the new
carbon market would create new jobs; that the manufacturing sector will lose a
few jobs; that household consumption will fall by only one percent at worst;
that increases in energy costs would be modest; and that overall costs would be
small enough to permit expansion of programs to offset the burden for low-income
households. The “Report” says that strict limits on ‘global warming’ pollution
can harness the power and creativity of capital markets, and that cap-and-trade
would work by “turning market failure into market success”. It assumes that if
fossil-fueled energy were artificially made more expensive other technologies
would emerge to replace it.
The “Report” is based not on theoretical
demonstration nor on empirical observation but on computer models – an expensive
and unreliable form of guesswork. It claims to be the first of its kind, but
there have been one or two others like it, such as the now
universally-discredited Stern Report , which used the same unscientific rhetoric
of “market failure” together with overstatements of the imagined consequences of
anthropogenic “global warming” as a substitute for rigorous economic analysis.
The conclusions of the “Report” are unsound, and computer models can be – and
have been – deployed to demonstrate results diametrically opposite to those
which the “Report” advances.
“We cannot afford to wait, or
‘catastrophic climate change’ will occur”
Late in 2006 the
“Institute for Public Policy Research”, a grandly-titled and
extravagantly-funded pressure group in the UK, first proposed that the
international Left should from then on declare that the science of “global
warming” was settled. This proposal was accepted with alacrity by bodies
worldwide such as the “Natural Resources Defense Fund” and the “Environmental
Defense Fund”.
Not a single scientific authority or reference is cited in
the “Report” for any of the supposed catastrophes arising from “global warming”
that it mentions. However, peer-reviewed papers throughout the scientific
journals refute such conclusions:
Catastrophe? What
catastrophe?
There is no scientific “consensus” in the
peer-reviewed literature to the effect that “global warming” is an actual or
potential “catastrophe”, still less that “allowing greenhouse-gas emissions to
increase unchecked is an invitation to catastrophe”. A recently-published
peer-reviewed paper (Schulte , 2008) that surveyed 539 papers in the scientific
journals containing the words “global climate change” and published between
January 2004 and mid-February 2007 found that not a single paper provided any
evidence whatsoever that “global warming” might be even potentially
“catastrophic”. Only one of the 539 papers reviewed even mentioned the
possibility of “catastrophe”, but without offering any
evidence.
“Climate Change Is Real.” What
reality?
Next, the “Report” says, “‘Global warming is real”.
This point was well and bluntly addressed in the spring of 2006 in a letter from
61 leading scientists in climate and related fields to the Canadian Prime
Minister :
“‘Climate change is real’ is a meaningless phrase used
repeatedly by activists to convince the public that a climate catastrophe is
looming and humanity is the cause. Neither of these fears is justified. Global
climate changes all the time due to natural causes and the human impact still
remains impossible to distinguish from this natural
‘noise.’”
Warming? What warming?
The “Report’s”
assertion that the “possible severity” of the consequences of “global warming”
is becoming “increasingly clear” is not and cannot be based on any scientific
view. “Global warming” began at the end of the Maunder Minimum in 1700 and
continued at a near-uniform rate of 0.5-0.7 degrees C (0.9-1.2 F) per century
until 1998, when it paused. There has been no statistically-significant increase
in mean global surface temperature since 1998. In the past six and a half years
global temperatures have been falling at an impressive rate equivalent to 0.4
degrees C (0.7 F) per decade:
Unpredicted trend: Since
late 2001, the trend of global surface temperatures has been downward. “Global
warming” paused in 1998; and, though it may resume in future years, the rate of
warming is less than that which the models relied upon by the IPCC had
projected. Source: Hadley Centre for Forecasting / Climate Research Unit,
University of East Anglia.
Carbon dioxide causes some warming: therefore,
the upward trend in temperatures over the past 300 years, for which
steadily-increasing solar activity was chiefly but not solely responsible, may
well resume in future. However, the rate at which foreseeable increases in
atmospheric carbon dioxide concentration will cause further warming is by no
means “settled science”; and, as the above graph indicates, it is becoming
increasingly clear with each passing year that the very high official estimates
of climate sensitivity to anthropogenic CO2 enrichment are proving to be
exaggerations.
For instance, Lindzen (2008) says that the failure of
computer models accurately to predict the behavior of the tropical upper
troposphere, a problem identified and quantified in Douglass et al. (2004, 2006,
2007), requires all of the IPCC’s estimates of climate sensitivity to be divided
by at least three. If Professor Lindzen is right, then there is no “climate
crisis”: a small, harmless, and beneficial warming rate will continue, and that
is all. For a short account of the combined magnitude of this and other errors
in the IPCC’s official calculations of climate sensitivity, see the Technical
Appendix.
Drought? What drought?
The “Report”
says widespread famine may be caused by droughts arising from “global warming”.
However, the Clausius-Clapeyron relation mandates that, as the climate warms,
the space occupied by the atmosphere is capable of carrying near-exponentially
more water vapor. Therefore, in general, there will be fewer droughts. This
effect has already been observed and reported. For instance, the Sahara has
shrunk by 300,000 km2 in the past quarter of a century (Nicholson, 1998,
2001).
The shrinking Sahara: Throughout the period of strong “global
warming”, the Sahara’s extent shrank by 300,000 km2. Source: Nicholson (1998,
2001).
Nomadic tribes have been able to move back to areas of the Sahara
that have not been settled within living memory. This is the very reverse of the
pattern of “widespread drought” predicted by the “Report”. Indeed, the fact that
the carrying-capacity of the atmosphere for water vapor becomes greater as the
climate warms has been cited by health authorities such as the World Health
Organization and the Department of Health in the United Kingdom as a (false)
pretext for statements that warmer and hence wetter weather will increase the
world’s standing water and will hence encourage the malaria mosquito to breed
(though there is no scientific basis for this conclusion either).
Though
the pattern of drought and flood has fluctuated in the past and will do so again
in the future, there is no sound scientific reason to suppose that warmer
weather will mean more droughts. The computerized guesswork of the models relied
upon by the UN failed to predict the shrinking of the Sahara, and it provides no
basis for concluding that drought will spread. There are fewer droughts in many
parts of the world today than there was in the first half of the 20th century,
when John Steinbeck wrote The Grapes of Wrath, in which he graphically described
the severe droughts of that era in the Great Plains – droughts that have not
occurred in the warmer weather since.
Threat to corals? What
threat?
The “Report’s” assertion that all the world’s coral
reefs are imminently threatened by “global warming” is also without scientific
foundation . Coral reefs are not threatened by warmer oceans : most of them
prefer warmer water. Corals first came into existence by algal symbiosis some
175 million years ago, in the Triassic era, and some say they date back 500
million years. For most of that period, global temperatures are thought to have
been 7 degrees Celsius (12.5 F) warmer than the present. The corals not merely
survived but throve. To the extent that they are threatened at all, the threat
is from pollution, and from dynamiting in aid of fishing.
The coral
bleaching that was observed in 1998 was the consequence of the exceptional and
sudden El Nino Southern Oscillation of that year, whose intensity had only two
precedents in the previous 300 years. Both of the previous intense El Ninos also
produced coral bleaching, and the corals readily survived it (Hendy et al.,
2004). Going back further, Precht and Aronson (2004) concluded that between
10,000 to 6,000 years ago extratropical North Atlantic sea surface temperatures
were 2-3 degrees C (3.5-5.5 F) warmer than at present and coral reefs
flourished. They reported that the fossil record clearly demonstrates the
ability of corals to expand their ranges poleward in response to global warming
and to "reconstitute reef communities in the face of rapid environmental
change." They also report that corals are expanding their territories: "There is
mounting evidence that coral species are responding to recent patterns of
increased SSTs by expanding their latitudinal ranges."
Thriving
corals: reefs are not threatened by “global warming”
Sea-level rise? What
sea-level rise?
Finally, the “Report” mentions the possibility
of “sea levels rising by several meters over the course of a few centuries”.
This is true, but the implication that it arises chiefly from manmade “global
warming” is entirely false. In the 10,000 years since the end of the last Ice
Age, sea level has risen by 130 meters (400 feet): an average of 1.3 m (4 ft)
per century. However, most of the world’s land-based ice has long since melted,
and nine-tenths of what remains – on the high plateaux of Greenland and
Antarctica – is not at risk unless temperatures are sustained at least 2 degrees
C (3.5 F) above today’s for several millennia (IPCC, 2007). Indeed, in each of
the past four interglacial periods neither Greenland nor Antarctica lost their
ice sheets. Greenland, but not Antarctica, lost its ice sheet in the
interglacial period 850,000 years ago: but temperatures in each of the
interglacials of the past million years were at least 5 degrees C (9 F) higher
than today’s, entirely through natural causes.
There is, therefore, no
scientific basis for the oft-repeated suggestion that “global warming” will melt
so much ice that sea levels will imminently rise by Al Gore’s imagined 20 ft.
The IPCC has now reduced its estimate of the maximum sea-level rise to the year
2100 by one-third, from 0.88 m (3ft) to 0.59 m (<2ft), and nearly all of this
projected increase, if it arises, will come not from melting ice but from
thermosteric expansion – if the oceans continue to warm.
However, recent
detailed surveys, such as Lyman et al (2006, revised 2007) show no
statistically-significant warming at all. The oceans are 1100 times denser than
the surface atmosphere, and they are as deep in some places as the troposphere
is high: their thermal inertia, therefore, is immense. Moerner (2004), who has
studied sea level throughout his distinguished, 30-year professional career and
is recognized as the world’s foremost expert, says there is no basis even for
the UN’s best estimate of a 0.43 m (17 in) rise in sea level to 2100. His own
best estimate is that there will be little increase above that which was
observed in the 20th century – just 8 inches.
The published literature –
all of the papers cited above are peer-reviewed except the documents of the IPCC
– demonstrates that there is no scientific basis for any of the alarmist
propositions in the cited paragraph of the “Report” to the effect that there is
a danger of imminent “catastrophe” arising from man-made “global
warming”.
There is no long-term danger of catastrophe either: on the
evidence of past interglacial records, inferred from temperature proxies derived
from ratios of oxygen isotopes in samples of air trapped in Antarctic ice-cores
(Petit et al., 1999), the world is already overdue for the next Ice Age, so that
after several further millennia, if not sooner, it is global cooling, not
“global warming”, that will be the primary concern of humankind.
In
short, none of the imagined disasters is at all likely to occur before the onset
of the next Ice Age, even by natural causes – still less as a result of
humankind’s activities. “Global warming” is not a global crisis. It requires no
economic intervention by national governments, still less by supranational
entities. Cap-and-trade is, therefore, unnecessary.
“We can
afford an aggressive cap-and-trade policy to tackle ‘global
warming’”
The “Report” states or implies that “cap-and-trade”
works well enough to make a difference to the climate; that it costs very
little; and that it will not damage the US economy.
The truth is that
“cap and trade” does not work. The European Union’s carbon emissions are rising
yearly, while those of George Bush’s US are falling yearly. In the EU,
“cap-and-trade” has already been tried twice and has spectacularly failed twice,
at huge cost. The environmental result: nil. Europe’s emissions continue to
rise. There have been similar failures elsewhere in the world. A recent analysis
by the U.S. Environmental Protection Agency of the Lieberman-Warner bill
projects that costs of electrical power and gasoline would rise very sharply.
Gasoline would cost about 53 cents per gallon more in 2030 and $1.40 per gallon
more in 2050.
Nigel Lawson, the former UK Treasury Secretary, in his book
An Appeal to Reason – A Cool Look at “Global Warming”, dismisses “cap-and-trade”
in a few crisp and characteristically perceptive paragraphs –
“If western
governments, at least in Europe, are going to remain obsessed with the alleged
need to cut back sharply on CO2 emissions by increasing the cost of carbon, what
is the best means of achieving this? The route the politicians (but very few
economists) prefer is known as “cap and trade” – a regime in which emissions, or
some of them, are statutorily capped, and the emitters are then free to trade
the emission permits which result from this system. The trouble is that both in
theory and in practice (for it has, to some extent, been put into practice) it
is a method that has little to commend it.
“For one thing, it is in no
sense the ‘market’ solution that it purports to be. It is essentially a
government-controlled, administrative rationing system, in which the rations can
subsequently be traded. It is rather as if, instead of seeking to cut back on
smoking by taxing it, we were to allocate Soviet-style production permits to the
cigarette manufacturers, which they were then permitted to buy and sell amongst
themselves. Of course, for the market-makers and other middlemen who trade in
the CO2 emissions permits, it is indeed a market, and one which they will not
hear a word said against: for them it presents a lucrative and – they hope –
growing business opportunity.
“Among its many other drawbacks, cap and
trade is arbitrary and distortionary, covering some emissions but not others (it
is impractical, for example to extend it to the personal and household sector,
including motoring). For those industries where it does apply, it is
anti-competitive, since permits are issued to existing emitters, and not to new
entrants, who have to purchase them from the market. In general, the
administrative allocation system scores badly on transparency, and lends itself
to lobbying, corruption, and abuse of one kind or another. This is even more
pronounced in an international scheme, when each government is under pressure to
allocate generously to its own national emitters. Another problem is that it
injects an artificial volatility into the price of energy, making rational
investment decisions more difficult – not least any decision to invest in
low-carbon or non-carbon energy. And, inevitably, the ethereal nature of the
commodity being traded makes it particularly hard to police.
“The only
substantial emissions-trading scheme so far attempted, the European Union’s ETS,
exhibits all these fundamental flaws – and indeed several more, as recent
studies have shown. In practice, it has done nothing to reduce emissions, and
has merely awarded subsidies to selected emitters. In theory, some of the
disadvantages of the scheme could be avoided if the emissions permits were
auctioned, rather than given away, but the design of an auction to cover all
emitters – including the personal sector – and extending it internationally
would be mind-bogglingly complex and contentious, if indeed it could be done at
all. Which is why, for the new and allegedly improved second (2008-2012) phase
of the ETS (the first phase is universally agreed, except by those who have made
money out of it, to have been a farce), the EU has decided that 98.5% of the
permits should be allocated and only 1.5% auctioned.
There are two other
forms of governmentally-sponsored carbon trading. Both are impossible to
supervise and continue to suffer from such widespread abuse that their net
effect on the climate is probably an increase in total carbon emissions. First,
the “Clean Development Mechanism” set up under the Kyoto Agreement allows
developed countries bound by Kyoto targets to buy “certified emissions
reductions” from developing countries rather than cutting its own emissions. The
UN is supposed to declare that the reductions would not have occurred in any
event and have not been offset by any increase in emissions somewhere
else.
China and India have both exploited the Clean Development Mechanism
to the full, and greatly to their profit, but without any environmental benefit
whatsoever to our planet. Chinese and Indian producers of chlorofluorocarbons,
powerful greenhouse gases, are able to earn massive windfall profits by opening
or buying plants designed to emit halocarbons – tens of thousands of times more
potent than CO2 as greenhouse gases – and then by receiving cash payments via
the Clean Development Mechanism to close them down again. Since the payments are
scaled to reflect the “global warming potential” of the greenhouse gases emitted
by the plants, the profiteers by this scam are making billions. The profits – at
the expense of the West – are so gross that the Chinese Communist regime now
levies a special windfall tax on them, which it can then spend on paying the
cost of its declared program of opening two or three new coal-fired,
greenhouse-gas-emitting power stations every week (for the sheer scale of this
program, see the Annual Statistical Communiqué of the “People’s” “Republic” of
China, 2006). It is difficult to see any environmental merit whatsoever in this
mechanism.
Secondly, the “Joint Implementation”, also established under
the Kyoto Protocol, allows developed countries emitting below their Kyoto
thresholds to sell “carbon credits” (cynically but accurately known on the
financial markets as “hot air”) to others who cannot meet their own thresholds.
However, the only Kyoto signatory emitting well below its threshold, which the
Protocol defines as 5% less than actual 1990 emissions, is Russia, because the
collapse of Communism brought thousands of State-subsidized heavy industries to
a sudden end. Russia at first stood out against the Kyoto Protocol but, more
recently, its leaders realized that it could profit by Joint Implementation to
the tune of tens of billions at the expense of the West. Suddenly, it ratified
Kyoto. Soon, the profits will roll in, and we will be paying.
There is
also a private-sector scheme known as “carbon offsetting,” by which jet-setting
celebrities like Al Gore can publicly parade the pretence that their
extravagant, carbon-emitting lifestyle is not really adding anything to manmade
greenhouse-gas emissions. All they have to do is to buy the modern equivalent of
the Indulgences sold for profit by unscrupulous pastors in the mediaeval Church.
The Indulgences, coyly marketed under the name “carbon offsets”, are sold by
various private scamsters, who craftily suggest to penitents that they can salve
their consciences for, say, the carbon emissions arising from a transatlantic
flight by paying as little as $5 towards the planting of trees that may or may
not take place, and might or might not have taken place anyway. Type “carbon
offsets” into Google and look at almost any of the myriad scams on offer. Most
of them are so transparently fraudulent that it is at first blush astonishing
that prosecutions have not resulted.
For it is the unique, common
characteristic of all forms of carbon trading – whether by cap-and-trade, the
“Clean” Development Mechanism, the Joint Implementation, carbon offsets, or any
other device in the panoply of international nonsense that has sprung into being
so profitably for the scamsters and their allies among the international enemies
of the West, and so expensively for the rest of us – that not only both parties
to each transaction but also all of the States or supranational entities
nominally supervising and regulating them have a direct and powerful vested
interest in overstating both the scale and the significance of the
transactions.
The emitter wishes to salve his conscience and receive
absolution by pretending that he has done all that is necessary to make him and
his household or enterprise fashionably (though unnecessarily, and
climate-irrelevantly) “carbon-neutral”. The counterparty to the emitter’s
transaction wishes to attract more business from penitents by suggesting to them
that for unrealistically small sums they can be forgiven all their carbon sins.
The regulators and legislators wish to demonstrate to their voters (in those
countries – unlike the European Union, or Rhodesia – where voters still matter,
and still retain the power to choose and to dismiss those who govern them) that
they are playing a full and successful part in the great Sancho Panza crusade to
“Save The Planet”.
No surprise, then, that notwithstanding all the
rhetoric and all the activity and all the “Reports” about the desirability of
carbon trading, the trend in worldwide carbon emissions continues relentlessly
upward, and at an accelerating rate. Though “carbon offsetting” is indeed
enriching the wealthy market-fixers, scamsters, and regulators, while further
impoverishing the poor citizenry, it is not – back in the real world – actually
offsetting any emissions of carbon dioxide at all: nor is it ever likely to do
so.
For, even if the entire Western world were to close down its
economies altogether, and revert to the Stone Age but without even the ability
to light fires, the planned growth in emissions in India and China alone would
replace the West’s entire emissions within little more than a decade.
The
central truth about “global warming” is that from here on it is the emerging
tigers of Asia who will be the world’s dominant emitters. The West is no longer
the chief problem, and no longer holds the solution in its own hands. We are
bit-part players.
For the foreseeable future, therefore (setting aside
the small decline that has recently occurred because the exceptionally cold
winter of 2007/8 cooled the climate-relevant surface or “mixed” layer of the
oceans and allowed that layer to take up unusually large quantities of CO2 from
the atmosphere), carbon dioxide concentrations in the atmosphere will continue
to rise as they have throughout the half-century since modern gas-chromatograph
measurements were first taken by the formidable Charles David Keeling on the
shoulder of the Mauna Loa volcano in March 1958.
Therefore, it would not
be responsible for the international community, or for any individual nation, to
plan on any other basis than that by the end of this century there will be a
great deal more carbon dioxide in the atmosphere than there is today. Not that
that matters, for its effect on the climate will be negligible and generally
beneficial – see the Technical Appendix.
Yet the principal objection to
all forms of carbon trading, however elaborate and however piously intended, is
not that it is inherently and inescapably fraudulent, nor that it is inevitably
and ineluctably futile, but that it delivers no environmental benefit whatever
in return for its massive cost – a cost which, as we shall see, falls almost
exclusively upon the poorest while considerably enriching the richest. Carbon
trading is Robin Hood in reverse, robbing the poor to enrich the rich. Abraham
Lincoln once said, “You cannot make the poor rich by making the rich poor.” You
certainly cannot make the poor rich by making the poor still poorer: that is the
chief economic effect of carbon trading.
The real reason why carbon
trading is a wasteful menace that ought to be forbidden by law is that it is
altogether unnecessary. It is unnecessary not only because, as we have seen, the
world has not warmed for a decade and is not likely to warm at more than a
minuscule, harmless, and beneficial fraction of the rate luridly but
inaccurately projected by the IPCC and its self-serving adherents in the
international classe politique. It is unnecessary, above all, because the iron
economic law of supply and demand is already driving up the cost of all
carbon-based fuels, altogether irrespective of any intervention by etatiste
meddlers.
It is a truism that the supply of fossil fuels is finite. Also,
it is demonstrable not only that the cost of exploration is rising as a
proportion of the exploitable reserves discovered but also that the cost of
extraction is rising as a direct result of the political risks consequent upon
the location of most of those reserves in the territories of unstable,
undemocratic regimes that are for various reasons implacably hostile to the free
West.
However, it is demand-side pressure, more than supply-side
scarcity, that is chiefly responsible for the recent galloping inflation in the
prices of fossil fuels, notably gasoline, currently trading at 1000% of its
world price little more than a decade ago. This hyperinflation in the cost of
fossil fuels is chiefly driven by the sudden surge in demand from emerging
nations such as India and China. And the more we use carbon trading to close
down our own economies and destroy the jobs of our working people, the more we
shall stimulate that already-burgeoning demand for carbon fuels in India and
China.
It is very likely that today’s oil price inflation, driven
partly by limited and politically-uncertain supply but chiefly by
ever-increasing world demand, will continue. Therefore, even if there were any
imperative need for action to avert a “climate crisis” (which there is not: see
the Technical Appendix), there would still be no need for national or
international governmental action to drive up fossil-fuel prices any further:
indeed, to do so would be particularly harmful to those on low incomes, and
might dangerously deepen the present recession, without delivering any
environmental benefit.
The deepening of a worldwide recession, though it
is a mere inconvenience to the wealthy nations of the free West, has immediate
and fatal consequences in the poorer nations, whose citizens are already
starving as a direct result of the unscientific, now-discredited,
bureaucratically-driven dash for biofuels , and are now menaced not only by the
galloping increases in fuel prices caused by the surge in international demand
but also – and quite unnecessarily – by the threat from the international classe
politique artificially to increase fuel prices still further by means of “cap
and trade”.
In a crude attempt to circumvent and downplay the fact of
fossil-fuel hyperinflation, the EDF’s Report” disingenuously tries to argue – as
did the now-defunct Stern Report – that the cost of cap-and-trade is negligible
and will not add anything much to fossil fuel prices. In one respect, this is
true. The first collapse of the European Union’s characteristically bureaucratic
and extravagantly pointless cap-and-trade system was engendered by a huge fraud
at the heart the system’s very construction. Under the system as originally
conceived – or, rather, misconceived – every member-State was allowed to set its
own emission limits. As a result, almost every member-State except Britain,
whose current crop of ministers and civil servants are lamentably inexperienced
and out of their depth in international negotiations, set themselves emission
limits that actually exceeded previous total emissions. No surprise, then, those
emissions in the EU continued to rise notwithstanding the introduction of
cap-and-trade, so that, within a very short time, emissions permits were trading
at less than $1 per tonne of CO2. This was indeed cheap – so cheap that it was
comfortably exceeded by the monstrous bureaucratic handling charges involved in
the trading, whereupon the scam collapsed.
The lesson to be learned from
this typically incompetent failure on the part of the EU, whose officials are
not subject to any effective democratic scrutiny, audit, or recall and who are
accordingly not under any pressure to get things right, is this: if
cap-and-trade is as cheap as the “Report” suggests, it will have no effect on
carbon emissions. The corollary is that, if cap-and-trade actually reduces
emissions, it can only do so if it is sufficiently expensive. Otherwise, as the
failure of the EU scheme demonstrates, the environmental impact of
“cap-and-trade” is actually negative: emissions rise, in a fine demonstration of
the Law of Opposite Consequences: whenever a government attempts to interfere in
the workings of the economy, even for beneficial purposes, it will be likely to
trigger consequences that are not merely unintended but the diametric opposite
of those that were, however piously, intended.
What, then, might
the true cost of an effective cap-and-trade system be?
This
question was recently examined in a detailed analysis of the Lieberman-Warner
“Climate Security Act” by the American Council for Capital Formation and the
National Association of Manufacturers, which concluded as follows –
The
CO2 emissions allowance price needed to reduce energy use to meet the Bill’s
targets is estimated at $55 to $64 per metric ton of CO2 in 2020, rising to
between $227 to $271 per ton in 2030.
The cost of the allowances raises
energy prices for residential consumers by 26% to 36% in 2020, and 108% to 146%
in 2030 for natural gas, and 28% to 33% in 2020, and 101% to 129% in 2030 for
electricity. In short, a workable carbon trading scheme, even if it were
necessary, could be expected to double the price of basic household
energy.
These and other increased energy costs will slow the US economy
(at today’s prices) by $151 billion to $210 billion in 2020 and $631 billion to
$669 billion in 2030, causing job losses of between 1.2 million to 1.8 million
in 2020 and 3 million to 4 million by 2030. If anything, these figures for job
losses are conservative, since the calculation ignores any second-order or
“knock-on” effects caused by the rapid and worldwide economic dislocation that
“cap-and-trade” would cause.
As manufacturing slows, the value of
shipments will fall by 3.2 % to 4% in 2020 under the low and high cost cases; by
2030 the value of shipments will fall by 8.3 % to 8.5% under the two cases. The
higher energy costs, lower economic activity and fewer jobs will in turn reduce
average household income (at today’s prices) by $739 to $2,927 in 2020 and by
between $4,022 and $6,752 in 2030. Here too, the analysis is very much on the
conservative side: for the sole consequence of the fatal self-inflicted wound of
carbon trading on the economies of the free West will be to transfer
manufacturing activity and the jobs that go with it from our own shores to
China, where no cap-and-trade system will be put in place, and where the carbon
dioxide emitted per unit of electricity generated is far higher than in the
West, as is the concomitant particulate pollution. In short, the inevitable
consequence of introducing a cap-and-trade system in the West will be to
increase the world’s carbon emissions and its pollution, while pointlessly
damaging our own economies.
The manufacturers’ analysis, like the
“Report”, was performed using computer models, but coming to an opposite result,
illustrating that the output of computer models is more likely to reflect the
inclinations of their users than to reveal objective reality. If anything,
however, the manufacturers’ analysis of the Lieberman-Warner Bill errs very much
on the side of understating the true costs of cap-and-trade schemes: for the
analysis optimistically assumes that nuclear power will be readily available
(notwithstanding the considerable political resistance to it that persists);
that carbon capture and storage will be practicable and affordable (though the
workability and cost of this technology has not yet been demonstrated); that
wind and biomass technologies will work (notwithstanding that no unsubsidized
wind-farm is profitable, and that even the UN has now abandoned its earlier
recommendation of biofuels because of their significant contribution to the
recent, sudden doubling of world food prices); and that low-cost offsets against
carbon emissions will be obtainable (though there is no evidence that they will
be).
The manufacturers’ analysis also greatly underestimates the profound
economic dislocation that will arise from the growing number of proposals to
shut down up to 90% of the economies of the West. If any action were required to
mitigate carbon dioxide emissions, over and above the inexorably-rising
international prices that will mitigate them without the need for any
governmental intervention, cap-and-trade would be one of the least efficient
methods. Straightforward taxation of gasoline and of electricity would be far
simpler.
Why, then, does the “Report” argue for the complex, costly,
fraud-prone scheme that is cap-and-trade, rather than for simple,
marginal-cost-free increases in energy taxes? The reason is purely political.
Precisely because cap-and-trade is so complex, numerous middlemen are involved,
each of whom will enrich himself at our expense. Also, energy-producing
corporations that would oppose the increased taxation of their product can be
persuaded to back cap-and-trade because the opportunities for fraud are so great
that the corporations can devise ways of making very substantial profits, again
at the expense of the ultimate user – you and me. Private-sector entities that
would oppose additional taxation are being bribed, in effect, by the promise
that if they ignore the scientific consensus to the effect that “global warming”
will not be catastrophic (Schulte, 2008, op. cit.), they will be able to profit
from the rigged market in licenses to emit.
The “Report” by the
Environmental Defense Fund not only echoes the Stern Report in artificially
overstating the climate consequences of anthropogenic influence on the
atmosphere, but also in artificially understating the costs of mitigation and
artificially evaluating future costs by the use of a discount rate well below
that which commercial entities would use: it also makes the naïve and
scientifically-unjustifiable assumption that if carbon-based fuels are made more
expensive new technologies to produce energy more cheaply will certainly emerge
to replace them.
Without this speculative assumption, the entire “Report”
collapses. Though it is self-evident that as the price of gasoline and
electricity rises the rewards for those able to find or develop alternative
sources of energy will correspondingly increase, there is no guarantee that
affordable or workable new technologies will emerge to replace the
old.
By the same token, one may not definitively assume that the higher
carbon-fuel prices that are inevitable regardless of cap-and-trade will not lead
to the rapid emergence of new energy technologies capable of replacing fossil
fuels as they run to exhaustion. However, the following difficulties in new
technologies are apparent:
Wind farms produce very small amounts of
electricity, at enormous landscape and environmental cost, particularly to large
game birds and to bats killed by the apparently-slow-moving but in fact very
fast-moving blades. The variability of the wind requires all rated capacities to
be divided by 4-6. Wind farms produce not a milliwatt when the wind is not
blowing strongly enough, so that fossil-fueled power stations have to be kept in
steam at all times to take up the load when the wind drops. Also, wind farms are
chiefly located a long way from where the power they generate is needed,
requiring expensive and unsightly transmission lines and causing substantial
transmission losses. Worst of all, the load variability caused by wind
fluctuations destabilizes any electricity grid to which the wind farms supply
power, so that they cannot safely contribute more than a small percentage of
total power supply even when the wind is blowing.
Hydro-electric power is
already almost as fully developed as it can be: there is little scope worldwide
for very large increases in hydro-electric capacity. Hydro power has killed more
people per kWh than almost any other form of power generation, largely through
the failure of dams.
Wave-power is still in its infancy, but it is
already apparent that building wave-power generating sets strong enough to cope
with the severe weather at sea will continue to be a severe drawback. Wave-power
requires still longer transmission lines than wind-power, since it is by
definition an offshore technology: transmission losses, therefore, will be
formidable.
Solar power continues to be beset by problems converting
solar energy to electrical energy. Though solar cells are steadily improving
their efficiency, they are only useful in sunny climates and on a
micro-generation scale. Larger solar collectors built in deserts suffer from
extremes of temperature, exposure to wind, and sandstorms. Maintenance costs are
high; reliability is low; transmission losses are substantial.
Nuclear
power, in the post-Chernobyl climate of irrational fear, will not make a
comeback soon, though the UK Labor Government, originally implacably opposed,
now recommends it. Unless fast-breeder reactors can be made to work, the world’s
supply of usable uranium will be exhausted in about half a century, at about the
same time as oil and gas. Attempts at nuclear fusion, both on the macro scale
(tokamaks and tori) and on the micro scale (aneutronic fusion) have proven
unsuccessful and little progress has been made after 40 years’
research.
Biofuels, once recommended by the “global warming” alarmists,
have disastrously doubled the price of staple foods and of agricultural land
worldwide, and are already causing millions to starve. Also, it has now been
calculated that the carbon emissions from the production and consumption of most
biofuels is actually greater than that of gasoline, underlying not only the
senselessness of biofuels but the need for governments to develop and enact
science-based policies free from interference by scientifically-illiterate
pressure-groups.
Hydrogen fuel cells are unreliable, expensive to produce
and to maintain, and subject to a series of so-far-incurable scientific
drawbacks that limit their usefulness.
Electric vehicles are slower than
conventional vehicles, have a shorter range, and cause carbon emissions not
significantly less than conventional vehicles, because the power that charges
them comes from conventional power stations.
It is always possible to
imagine entirely new space-age, high-tech solutions that might spring us free
from dependency upon carbon-based fuels. However, it is naïve to assume, as the
“Report” does, that such solutions will inevitably arise merely because
cap-and-trade will increase still further the price of carbon fuels that are
becoming daily more expensive in any event.
The danger in making such a
naively hopeful assumption is that, if we destroy our own economies in the hope
that some scientific deus ex machina will save us at the last moment, the lights
will begin to go out all over the West – and
soon.
Conclusion
If carbon trading works, it will
not be cheap. If it is cheap, it will not work. Either way, it is unnecessary,
both because “global warming” will not prove catastrophic and because the prices
of carbon-based fuels are already rising on their own without State
interference. It would accordingly be false to suggest that the cost of
cap-and-trade to the economy – whether financially or in terms of jobs,
household consumption, and growth – will be “minimal”.
Most proponents of
cap-and-trade have a vested and often financial direct interest in taking
advantage of their privileged positions to create and then to exploit a rigged
market, where the State will ration the volume of emissions that may be traded
and will, therefore, largely dictate the price, whether directly (as in the
dirigiste EU), or indirectly. It is at best disingenuous to pretend that the
cost to the victims of this or any rigged market will be
negligible.
Likewise, the artful notion that some of the additional
revenues contributed to governmental coffers by the victims of carbon trading
can be redeployed to alleviate the worst of its ill effects on the poorest
households is, in economic terms, absurd. For most households are poor:
therefore, State subsidies to minimize the cost to the poorest households of the
carbon trading that so greatly enriches those who rig and control the false
market in hot air will also minimize what little environmental benefit might be
expected from the scheme.
Above all, the self-inflicted economic wound of
making the use of carbon fuels more expensive in the free West than in Communist
China will merely transfer carbon emissions and jobs to the corrupt, polluting
regime that already has the worst environmental record in the world, and will
deploy the profits towards the continued expansion of its own network of
uniquely dirty, coal-fired power stations, to the detriment of its own
already-brutalized people, and to that of the environment, without any benefit
to the climate whatsoever. Seen in this light, carbon trading – like biofuels
before it – is lunacy.
The lunacy is culpable. For there is a moral
dimension. It is inhumane and cruel carelessly or callously to inflict upon the
poorest in the nation a policy – however currently fashionable – that is not
justified by any “climate crisis”, that would not have any effect on the climate
even if there were a “crisis”, that would cost the poorest households their
current right to affordable electrical power and transportation while at the
same time transferring overseas the jobs upon which our working people depend
for their livelihoods, and that is calculated – and perhaps even intended – to
enrich the enemies of freedom among the international community while actually
increasing the global carbon emissions that it was nominally intended to reduce.
Carbon trading is not merely futile – it is immoral, for it cannot but do harm
to the poorest people in our community: the very people who are most deserving
of our protection.
TECHNICAL APPENDIX
The IPCC’s
overstatement of the effect of increased atmospheric CO2 concentration on global
temperature.
This short technical appendix provides first an
empirical and then a theoretical demonstration that the IPCC and the computer
models upon which it relies overstate substantially the (very limited) effect of
anthropogenic CO2 enrichment on global mean surface temperature. This
illustrative analysis is confined to central estimates only: yet it compellingly
demonstrates the magnitude of the IPCC’s erroneous overstatement of climate
sensitivity to anthropogenic greenhouse-gas enrichment of the atmosphere.
I:
Empirical demonstration of climate sensitivity
The Stefan-Boltzmann
radiative-transfer equation (equation 1), not mentioned anywhere in the 2,500
pages of the IPCC’s 2001 and 2007 reports, is the equation by which any change
dF in net (outward minus inward) radiative flux at the tropopause may be
converted to a consequent temperature change at the surface.
F = esT4 W
m–2 (1)
where F is any radiative flux; e is emissivity, such that e = 1
for blackbodies, e = 0 for whitebodies, and e falls on the open interval (0, 1)
for greybodies; and s ˜ 5.67 x 10–8 is the Stefan-Boltzmann constant.
By
a thought-experiment, remove the oceans and the atmosphere and assume that the
Earth without them is a perfect blackbody, with emissivity 1: little error will
result from this assumption. Then, using equation (1), we may evaluate the mean
global true-blackbody surface temperature, taking total top-of-atmosphere solar
irradiance as 1368 Watts per square meter, and dividing it by 4 to allow for the
ratio of a disk to that of a sphere, so that F = 342 W m–2; e = 1; so
that
T = [F / (es)]¼ ˜ [(1368/4) / (5.67 x 10–8)]¼ ˜ 278.7 °K ˜ 5.5
°C
Now, add back the atmosphere, ocean, forests etc., and measure today’s
mean global surface temperature. It is approximately 15 °C (NCDC, 2008; Hadley
Centre/CRU, 2008; etc.). Accordingly, approximately 9.5 C of warming has
occurred, notwithstanding the substantial cooling effect of the increase in the
Earth's albedo (and the consequent reduction in outgoing longwave radiation)
arising from reflection from clouds, and, to a lesser extent, of reflection from
ice and from deserts and oceans.
Reduce the top-of-atmosphere solar
irradiance by 31%, from 1368 to 944 W m–2, to allow for today's albedo. Then,
without the warming effect of clouds, and without the greenhouse effect, mean
global surface temperature would be –
T = [F / (es)]¼ ˜ [(944/4) / (5.67
x 10–8)]¼ ˜ 254 °K ˜ –19 °C.
On this basis, a net warming of 34 °C has
arisen compared with the Earth as a true blackbody. Almost all of this warming
has arisen from natural causes. Of this warming of 34 °C, some 14 °C is
attributable to heat retention by clouds (Houghton, 2006). The remainder of the
warming – about 20 °C – is attributable to the warming effect of greenhouse
gases. Of this in turn, about two-thirds is attributable to water vapor, leaving
~7 C of warming caused by CO2 and all other greenhouse gases.
The
question, therefore, is how much more warming additional atmospheric CO2
concentration might cause. The IPCC considers that the forcing effect of CO2 is
approximately 5.35 times the natural logarithm of the bracketed term in equation
(2), which is the proportionate increase in CO2 –
ΔF ˜ 5.35 ln(C/C0) W
m–2, (2)
Thus, in the 50 years since Mauna Loa has kept records of CO2
concentration the IPCC’s central estimate of the CO2 forcing is –
ΔF ˜
5.35 ln(C/C0) ˜ 5.35 ln(385 / 315) ˜ 1.1 W m–2.
We translate this CO2
radiative forcing ΔF to temperature by evaluating ΔT as the product of three
factors –
ΔT = ΔF . k . f °K, (3)
where ΔT is temperature change,
ΔF is the radiative forcing, k ˜ 0.31 is the reciprocal of the Planck feedback
parameter, and f ˜ 3.1 is the multiplier that allows for temperature feedbacks.
Thus, if the IPCC’s central estimates, and if it were to be assumed (and, again,
little error in practice arises) that transient and equilibrium temperature
responses to radiative perturbation of the climate are near-identical, then,
using equation (3), the temperature of the past half-century should have risen
by –
ΔT = ΔF . k . f ˜ 1.1 x 0.31 x 3.1 ˜ 1 °C.
According to the
official global temperature series, global mean surface temperature has risen
over the period by ~0.5 °C (NCDC, 2008; Hadley/CRU, 2008; etc.). However,
McKitrick (2006, 2007) finds that the surface temperature series are biased by
urban heat-island effects, concluding – and his paper has not been challenged in
the literature – that global temperatures have risen by only half the rate
indicated by the temperature series. Accordingly, temperature has only risen by
0.25 °C over the period. From this, one must deduct approximately 0.1 °C for the
directly exothermic effects of human activities, leaving perhaps 0.15 °C, or
one-sixth of the value predicted using the IPCC’s central estimates,
attributable to anthropogenic CO2 enrichment. Thus, from 1998-2008, to summarize
–
ΔT ˜ (0.5 / 2) – 0.1 ˜ 0.15 °C. (4)
In these calculations, based
upon the empirical temperature data, we have assumed, again without introducing
significant error, that all anthropogenic forcings other than that from CO2
broadly self-cancel (in the IPCC’s analysis they are very slightly
net-negative), that equilibrium and transient temperature effects are
near-identical (Chylek, 2007), and that equilibrium ocean heat-uptake efficiency
is zero. Empirically, therefore, on the evidence of the very small temperature
change that has occurred, that the IPCC's central estimates of climate
sensitivity should be divided by ~6.
II: Theoretical
demonstration of climate sensitivity
A theoretical demonstration
for the magnitude of the appropriate reduction in the IPCC’s central estimate of
climate sensitivity will now be established. First, it will be necessary to
reduce the CO2 radiative forcing dF = 1.1 W m–2 to take account of the failure
of all of the computer models relied upon by the IPCC properly to represent the
behavior of the tropical mid-troposphere. The models have been programmed to
expect that, in accordance with the Clausius-Clapeyron relation, the tropical
upper troposphere will carry more water vapor as the climate warms, so that
temperature increase in the mid-troposphere over the tropics will be thrice that
at the tropical surface. However, the models misrepresent reality in two
fundamental respects. First, as Lindzen (1990) first suggested and Spencer
(2007) has subsequently confirmed, the tropical mid-troposphere actually becomes
drier as the atmosphere warms, as a result of increased advection of moist air
poleward from the tropical regions.
Secondly, Douglass and Knox (2004,
revised 2006), subject to a challenge by Thorne et al. (2007), to which Douglass
et al. (2007) is a definitive response, have demonstrated that there is already
so much water vapor near the tropical surface that the space occupied by the
tropical lower troposphere is already saturated with water vapor, preventing any
significant terrestrial radiative forcing in the equatorial region where the
preponderance of total outgoing longwave radiation might interact with the
atmosphere. In accordance with the analysis of Douglass et al., tropical
mid-troposphere temperatures, far from rising at thrice the surface rate, have
actually fallen over the past half-century. Therefore, Lindzen (2008), in a
paper that stands unchallenged in the literature, has recommended that all of
the IPCC's forcing estimates, including that from CO2, should be divided by
three.
The IPCC also overstates the no-feedbacks climate sensitivity
parameter k, having failed to adhere to the values recommended in the two papers
which it cites in justification of its chosen value. Furthermore, the IPCC and
its two cited papers fail to adjust both for the unequal latitudinal
distribution of outgoing longwave radiation and for the near-absence of outgoing
radiation at the Poles, caused partly by high albedo and partly by the very low
azimuth angle of the Sun at high latitudes. Making these and other appropriate
adjustments, according to a calculation by Dr. David Evans, reduces k from 0.31
°K W–1 m2 (IPCC, 2007) to 0.24 or thereby.
Since the feedback factor f is
dependent upon k, and since there is no justification for the IPCC's unstated
and unexplained 70% increase in the value of f since its 1995 report, f should
not be more than 2 and could be as little as 1.5. Taking all of these
adjustments into account, temperature change ΔT over the past half-century in
response to the increase in CO2 concentration over the period is –
ΔT =
[ΔF][k][f] ˜ [5.35 ln(385/315) / 3] [0.24] [1.75] ˜ 0.15 °C. (5)
The
theoretical result shown in equation (5), derived in accordance with the IPCC’s
methods appropriately adjusted, is in close correspondence with the earlier
empirical result in equation (4) above, derived from the observed record of
global mean surface temperature anomalies as adjusted to allow for the McKitrick
heat-island effects and for the directly exothermic activities of
humankind.
III: Conclusion
The conclusion, in
accordance with standard physical theory, is that the IPCC has overstated
climate sensitivity very substantially, and that any temperature increase in
consequence of anthropogenic enhancement of the greenhouse effect has been and
will continue to be minuscule, harmless, and, on balance, beneficial. At CO2
doubling compared with 1750, expected later this century, the further warming to
be expected compared with today’s temperatures is very likely to be less than 1
°C –
ΔT = ΔF . k . f ˜ [5.35 ln(550/385) / 3] [0.24] [1.75] ˜ 0.8
°C.
APPENDIX II
Climate Change Perspective
for
policy-makers
by
Christopher Monckton of
Brenchley
THATCHER’S RULE, “You have to get the
big ones right”, applies with the greatest force to those fields of policy where
wrong decisions could kill millions. The international community too often gets
the big ones wrong, and kills tens of millions, and does not care
much.
When the same lobbies that now demand action on climate change did
so on DDT 35 years ago, they got the science as wrong then as now. Instead of
restricting DDT to interior spraying of dwellings, they had it banned outright.
Result: 30-50 million (and counting) needlessly dead of malaria. Dr. Arata Kochi
of the WHO, announcing the end of the ban in 2006, said that too often politics
predominated: now it was (and is) necessary for the science and the data to
prevail.
With climate change, politics regrettably predominates. This
time, there is a dangerous complication: politicized science. The surprisingly
small group of scientists who started and still stir the “global warming” scare
have undesirably close financial links with politicians and corporations. Yet
the notion that “global warming” is so severe a threat that it demands major
increases in taxation and regulation, coupled with deep, strategic cuts in the
Western economies, would only be defensible if all of the following propositions
were true –
1. “The scientists, politicians, and news media
behind ‘global warming’ are honest”: They are not;
2. “The debate is over and
all credible climate scientists are agreed”: It is not; they are not;
3.
“Temperature today has risen exceptionally fast and above natural variability”:
It has not;
4. “Changes in solar activity do not significantly impact today’s
global warming”: They do;
5. “Greenhouse-gas increases are the main reason
why it is getting warmer”: They are not;
6. “The fingerprint of anthropogenic
greenhouse warming is clearly present”: It is absent;
7. “Computer models are
accurate enough to predict the climate reliably”: They cannot be;
8. “Global
warming is to blame for present and future climate disasters”: It is not;
9.
“Mitigating climate change will be cost-effective”: It will not;
10. “Taking
precautions, just in case, would be the responsible course”: It would not
be.
Each of these ten conformist propositions, every one of
which must be shown true before substantial policy changes can be considered
advisable, is demonstrated to be questionable at best, false at
worst.
There has been serious, serial scientific dishonesty,
misrepresentation, and exaggeration. Increasing numbers of peer-reviewed papers
are expressing open doubts about all of the main points of “global warming”
theory. Today’s temperature is well within natural climate variability. The
Sun’s activity is now declining from the recent 70-year-long solar Grand
Maximum, during which the Sun was more active, for longer, than at almost any
similar previous period in the past 11,400 years. Climate models have
exaggerated the effect of all greenhouse gases on temperature, and have also
increased the feedback multiplier by more than half in a decade, without
explanation or justification. The models do not accurately represent major
features of the climate, and it has long been proven impossible to predict the
long-run evolution of any mathematically-chaotic object, such as the climate,
unless one knows the initial state of the object to a degree of precision that,
with the climate, is in practice unattainable.
Politicians and the media
have flagrantly exaggerated the imagined effects on the climate of the
comparatively mild warming to be expected as a result of anthropogenic
greenhouse-gas enrichment. Sea level, for instance, will rise not by 20ft
imminently, as a notorious “global warming” profiteer and film presenter has
suggested, but by about 1ft over the next 100 years.
Economically,
adaptation to changes as they slowly occur is many times more cost-effective
than attempts at mitigation, which – for powerful political as well as
scientific reasons – are doomed to fail. The “precautionary principle” –
regulate now, just in case – has killed tens of millions in the recent past, and
is both scientifically and economically unworthy of the name
“principle”.
Conclusion: the climate may grow warmer, though much or all
of the warming may be offset over the coming century by a very substantial
decline in solar activity that is confidently predicted by the solar physicists;
but the relatively small amount of warming to be expected will be generally
beneficial.
Climate change is a non-problem, and the correct policy
response to a non-problem is to have the courage to do nothing. There are many
real environmental problems: climate is not one of them. And there are many real
political problems, not the least of which is the imminent scarcity of fuels,
minerals, and other essential commodities, nearly all of which are already
increasing rapidly in price.
Finally, the moral dimension is crucial. The
policies advocated to mitigate climate change would condemn the Third World to
remain abjectly poor, for unless all other countries cut their carbon emissions
atmospheric concentrations will continue to rise even if the entire West shuts
down and goes back to the Stone Age, but without even the ability to light
fires. If the poorer countries remain poor, their populations will paradoxically
continue to increase and, in the medium term, the global carbon footprint of
humankind will be greater than if mitigation had not been attempted. It is the
poor who have been the victims of unscientific but fashionable political
decisions in the recent past: it is they who will die in their tens of millions
if, yet again, an unscientific but fashionable political decision is taken by us
and inflicted upon them. We must get the science right or we shall get the
policy wrong. We have failed them before. We must not fail them
again.
