Update: apologies for formatting problems in a previous version

Last week a study claimed that 97-98
percent of the most published climate scientists agree with the
scientific consensus that man-made climate change is happening.
Well, duh. Of course they would: it's their livelihood. Anyway,
so do I. So do most `sceptics': they just argue about how much and
through what means. You can believe in man-made carbon dioxide
causing man-made climate change but not in net positive feedbacks
so you think the change will be mild, slow, hard to discern among
natural changes and far less likely to cause harm than
carbon-rationing policies: that's still within the range of
possibilities of the IPCC consensus.

I now see at firsthand how I
avoided hearing any good news when I was young. Where are the
pressure groups that have an interest in telling the good news?
They do not exist. By contrast, the behemoths of bad news, such as
Greenpeace, Friends of the Earth and WWF, spend hundreds of
millions of dollars a year and doom is their best fund-raiser.
Where is the news media's interest in checking out how pessimists'
predictions panned out before? There is none. By my count, Lester
Brown has now predicted a turning point in the rise of agricultural
yields six times since 1974, and been wrong each time. Paul Ehrlich
has been predicting mass starvation and mass cancer for 40 years.
He still predicts that `the world is coming to a turning

I spent an afternoon this week getting a personal tour of a cast
of the skeleton of Ardipithecus from Tim White, the leader of the
team that decsribed it. Call me a nerd, but I found it
spine-tingling to hold in my hands the skull of a 4.4.million year
old creature that might be very close to my own ancestor.
But it was the details that stole the show. The lack of

flared pelvis of a regular biped, the curved but relative short
metatarsals of the foot, the hints of very little sexual
The ecology, too, is intriguing. The Afar depression was not
such a depression then, and the weather was sufficiently damp for a
fairly rich forest to be growing there, albeit with patches of
grassland. By far the commonest antelopes were woodland-dwelling,
browsing kudu. Ardi herself ate fruits and nuts from trees, not
grasses -- this can be decided by isotopic analysis -- and she was
a good climber as well as a walker. Her molar teeth had not grown
robust like those of Lucy, for grinding grass seeds and roots, but
nor had they shrunk for processing soft fruit as those of modern

The fact that male chimpanzees systematically and stealthily
patrol their boundaries in groups to kill neighbouring males has

Pertinent to my recent response to New Scientist on ocean
acidification, Willis Eschenbach has a fascinating piece at Wattsupwiththat on a study of ocean pH along a transect from Hawaii
to Alaska. Turns out that the further north you go, the less
alkaline the ocean:
As one goes from Hawaii to Alaska
the pH slowly decreases along the transect, dropping from 8.05 all
the way down to 7.65. This is a change in pH of almost half a
The study also measured the change caused by carbon dioxide from
As part of an `interview' with me, New Scientist published
a critique by five scientists of two pages of my
book The Rational Optimist. Despite its tone, this critique only
confirms the accuracy of each of the statements in this section of
the book. After reading their critiques, I stand even more firmly
behind my conclusion that the threats to coral reefs from both
man-made warming and ocean acidification are unlikely to be severe,
rapid or urgent. In the case of acidification, this is underlined
by a recent paper, published since my book was written, summarising
the results of 372 papers and concluding that ocean acidification
`may not be the widespread problem conjured into the 21st century'.
The burden of proof is on those who see an urgent threat to corals
from warming and acidification. Here is what I wrote (in bold),
interspersed with summaries of the scientists' comments and my
Take coral reefs, which are
suffering horribly from pollution, silt, nutrient run-off and
fishing - especially the harvesting of herbivorous fishes that
otherwise keep reefs clean of algae. Yet environmentalists commonly
talk as if climate change is a far greater threat than these, and
they are cranking up the apocalyptic statements just as they did
wrongly about forests and acid rain
Andy Ridgwell says `I agree that at least for some reef systems,
other, and more local human factors such as fishing and pollution
may be the greater danger' and Jelle Bijma says `I do agree that,
for example, pollution and overfishing are also important problems,
some even more important than the current impact of ocean
acidification'. It was not therefore accurate of Liz Else to say
that the critics accuse me of failing `to recognize that there is
more to the health of corals than the amount of bicarbonate in the
sea' They do not - she has misrepresented their views and mine.
When I joined the Economist in 1983, Norman Macrae was the
deputy editor. He died last week at the age of 87. Soon after I
joined the staff, a thing called a computer terminal appeared on my
desk and my electric typewriter disappeared. Around that time,
Norman wrote a long article that became a book about the future. It
was one of the strangest things I had ever read.
It had boundless optimism --
Over the last decade, I have

Update: now that I have seen the five
scientists' comments, I find that remarkably they support and
vindicate each one of my factual statements. I have posted a
detailed analysis in
a separate blog post.
Here's a letter I just sent to New Scientist:
In her misleading article about my book,
among other errors Liz Else wrongly states that I `failed to
recognize that there is more to the health of corals than the
amount of bicarbonate in the sea'. Yet I clearly state in my book:
`take coral reefs, which are suffering horribly from pollution,
silt, nutrient runoff and fishing'. After doing the interview, Else
asked me for proof of a statement in my book that `Even with
tripled bicarbonate concentrations, corals show a continuing
increase in both photosynthesis and calcification.' Presumably this
was because her unnamed `experts' had challenged this statement. I
was happy to supply her with the following extract from Craig
Idso's book (`CO2, global warming and coral reefs'), which I cited
in my book, and with the reference it cites (Herfort et al 2008.
Journal of Phycology 44: 91-98): `This work reveals that additions
of HCO3- to synthetic seawater continue to increase the
calcification rate of Porites porites until the bicarbonate
concentration exceeded three times that of seawater…Similar
experiments on Acropora species showed that calcification and
photosynthetic rates in these corals were enhanced to an even
greater extent, with calcification continuing to increase above a
quadrupling of the HCO3- concentration and photosynthesis
saturating at triple the concentration of seawater'. I am sorry
that instead of quoting this exchange between us, Else chose to
fall back on unsubstantiated accusations of `misconceptions,
selective reporting and failure to see the significance of
historical changes in ocean acidity'. I took the trouble to back up
my claims; she should have done so for her accusations.
I just read a wonderful book Hybrid: the history and science of plant
breeding by Noel Kingsbury.
It contains a charming story, of a Moravian priest called Father
Schreiber, who was more interested in horticulture than holiness,
and whose parish included Gregor Mendel's birthplace, Hyncice. As
Kingsbury tells the tale:
Schreiber also had to face opposition,
or at least suspicion, from a conservative peasantry. So in order
to distribute new fruit varieties, he and the countess [Maria
Walpurga Truchsess-Zeil, no less] developed a technique that has
been used more than once down the ages in order to bring new genes
to the countryside: subterfuge. A nursery for trees was established
and word put out that these valuable seedlings were under guard,
the guards being instructed to make a lot of noise if they heard
anybody but not to actually arrest anyone. In a matter of days, all
the seedlings had been stolen.
I have written a longish piece about the human footprint on the

Here are a few extracts:
George Monbiot's recent attack on me in the Guardian is
misleading. I do not hate the state. In fact, my views are much
more balanced than Monbiot's selective quotations imply. I argue
that the state's role in sometimes impeding or destroying the
process that generates prosperity needs to be recognised, as people
from enslaved ancient Egyptians to modern North Koreans could
testify. But as I mention in my book, I don't think that free
markets, especially those in assets, should be completely
unregulated. I do argue that free and fair commerce has the
power to raise living standards.
Unlike Monbiot's article, my book isn't about me. It's about the
billions of other people in the world who, through ingenuity,
exchange and specialisation, have generated remarkable
Monbiot, remember is the man who once wrote: ``every time someone dies as a
result of floods in Bangladesh, an airline executive should be
dragged out of his office and drowned.'' (see, George, two can play
at selective quotation).
In my book I quote the English environmentalist Jonathon Porritt
as follows: 'It's blindingly obvious [that] completely
unsustainable population growth in most of Africa will keep it
permanently, hopelessly, stuck in deepest, darkest poverty.'
At first I had assumed that the quote, which I had found in
another book, must be out of context. Surely nobody would say
anything so foolish or so heartless. Surely he was caricaturing
some blimpish view from a reactionary? So I looked up the original
article, in The Ecologist in 2007, to be sure I was not being
unfair to quote him thus. You can read the whole article here. Here's the longer context of the
Yet the facts speak for themselves: the
fewer there are of us, the greater our personal carbon budgets -
and just remember we're starting from a baseline here in the UK of
around 12½ tonnes of CO2 per person!I can't
tell you how politically incorrect it is to spell things out in
those terms. Even those who are getting more and more
enthusiastic about the idea of personal carbon budgets (including
Environment Secretary David Miliband) wouldn't dream of giving
voice to such a crass calculation. Leaders of our
ever-so-right-on environment movement can barely bring themselves
to utter the dreaded "p" word. The Millennium Development
Goals don't mention population. Tony Blair's Commission for
Africa ignored it entirely, even though it's blindingly obvious
that completely unsustainable population growth in most of Africa
will keep it permanently, hopelessly stuck in deepest, darkest
poverty. Our very own Department for International Development
grits its teeth and reluctantly doles out little bits of money for
family planning projects, but the idea that it should be the
Department's No 1 priority - if it was remotely realistic about its
poverty alleviation aspirations - remains anathema to most
officials and ministers.
In my book I point out that an unemployed British father of
three on welfare today receives more in state support than a man on
the average wage received in income in 1957. It's an eye-catching
reminder of how wrong J K Galbraith was to argue that affluence in
the late 1950s had already gone too far.
Now the Institute of Fiscal Studies has compiled data on average incomes in Britain since 1961,
coming to the remarkable conclusion that
in real terms the bottom 25% are now
considerable richer than were the top 25% in 1961.

Listen to my interview on NPR's Leonard Lopate Show
and an MP3 of my interview on PM with Marc Colvin, in Australia
My good friend Dave Sands is not only a brilliant biologist -- I
cite him in The Rational Optimist arguing for genetic modification
to improve the quality rather than the quantity of food -- but a
very fine poet. He's profiled in yesterday's New York Times discussing his
latest theory that ice-forming pseudomonas bactera in the air play
a central role in precipitation:
In the last few years, Dr. Sands and
other researchers have accumulated evidence that the well-known
group of bacteria, long known to live on agricultural crops, are
far more widespread and may be part of a little-studied weather
ecosystem. The principle is well accepted, but how widespread the
phenomenon is remains a matter of debate.
If true, this could have all sorts of implications.

has society changed so fast and so radically? Life
now is completely different to how it was 32,000 years ago. It's
changed like that of no other species has. What's made that
difference? Clearly our genes haven't changed; this process has
happened far too fast for genetic change. My answer, bringing
together my evolutionary knowledge and a lot of economic reading,
is this: sex is to biology as exchange is to culture."
