As the Bishop of London said at the funeral service for the late Baroness Thatcher of Kesteven today, this is neither the time nor the place to argue about her legacy. Comments on this post are therefore disabled (until tomorrow at least). However, even putting aside politics, all those miners of coal who have have shown such crass disrespect for the late Margaret Thatcher need to bear in mind that mining coal is one of the most environmentally damaging things humans have ever done. Therefore, in seeking to make the UK less dependent upon coal, it could be argued that Mrs Thatcher’s greatest mistake was pursuing gas rather than renewable energy. This mistake, replicated the world over for several decades now, is a mistake for which we and our children and our children’s children shall pay a very heavy price.
“An error doesn’t become a mistake until you refuse to correct it” — Orlando A. Battista.
I happened to stumble across a BBC TV Horizon special, entitled ‘Tomorrow’s World’ last Thursday. It begins with a fascinating review of humankind’s history of – and propensity for – invention. It also explains some truly fascinating – and inspiring – developments in the spheres of space exploration, nanotechnology, biotechnology, and power generation.
In the introduction, the programme presenter and narrator Liz Bronnin explains how, after 100s of thousands of years of technological stagnation, the fast-moving world of technological innovation is very definitely a modern invention.
She then looks at how, since our governments announced they were not going to do so, private investors are now involved in a race to return to the Moon (and win a $US 20 million prize). Just after 11 minutes in, however, economist Marianna Mazzucato makes the point that private sector development would never happen unless governments first spent money innovating (just look at your Computer, iPhone, or SatNav).
This is followed by an examination of the invention of graphene (i.e. the repeated use of sellotape to produce a film of graphite comprised of only one layer of carbon atoms in a hexagonal matrix). It is truly astonishing what graphene can do – including carry the weight of a cat…
After 23 minutes, a variety of talking heads demonstrate the complexity of modern science and the impossibility of any one person understanding it all. However, Bronnin then presents the example of Professor Robert Langer at MIT. What he is doing – and enabling others to do – is truly amazing; including potentially doing away with the need for chemotherapy to treat cancer.
After about 32 minutes, Bronnin introduces the power of the Internet to promote innovation – crowd-sourcing research funding and the concept of open-source technology – the complete abrogation of intellectual copyright… It is a fundamental challenge to globalised Capitalism; but it may well be the solution to many of our problems…
However, to me, the final third of the programme is by far the most fascinating… It looks at the challenges of finding a replacement for fossil fuels. It provides a very clear message that this is a technological challenge driven by the reality of physics – not by ideology.
It presents the case for synthetic biology, which has now succeeded in genetically modifying cyanobacteria so that they use photosynthesis to produce ethanol. This is brilliant, but, it is still only recycling CO2 (it is not removing it from the biosphere). With this technology, we could stop the CO2 content of the atmosphere from rising (but it will not help get it down again).
In the final 10 minutes of the programme, Bronnin presents the inspiring case of the British inventor, Michael Pritchard, who miniaturised water treatment technology as a result of watching the aftermath of the Boxing Day tsunami of 2004; when people were surrounded by water they could not drink… Indeed, to prove that it works, he even gets Bronnin (at 54 minutes) to drink water extracted from a tank including all kinds of unpleasant things including dog pooh…
For all these reasons, if you have not seen it, I would recommend that you watch the programme:
Re-engineering nature for our benefit will, without doubt, be very very useful. However, I still think the optimism of the comment at the very end of the programme “…I never worry about the future of the human race, because I think we are totally capable of solving problems…” is very unwise. This is because anthropogenic climate disruption is a problem that is getting harder to solve the longer we fail to address it effectively.
Bronnin concludes by saying that, “it is an exciting time to be alive…” However, I remain very nervous. This is because, as Professor Peter Styles of Keele University – a strong supporter of the hydraulic fracturing industry – recently acknowledged, it will be impossible for carbon capture and storage to remove enough CO2 from the atmosphere to prevent very significant changes to our climate. This is because of the collective hypnosis that deludes most people into seeing perpetual economic growth as the solution to all our problems.
In short, I am certain that technology alone cannot save us. In order to avoid the ecological catastrophe that all but the most ideologically-prejudiced and wilfully-blind can see developing all around us… we need to modify our behaviour: This primarily means that we need to acknowledge the injustice of a “use it up and wear it out” mentality and, as individuals, all learn to use an awful lot less energy.
Climate change “sceptics” have picked a fight with history and science – primarily with the concept of Entropy - and they will lose. The only question that remains is this: Are we going to let them put us all in (what xraymike79 recently called) ‘the dustbin of failed evolutionary experiments’.
So said Lord (Julian) Hunt, Vice President of GLOBE and a former Director General of the UK’s Meteorological Office, in an article published in The Times newspaper on 2 April 2013 (behind paywall). Fortunately (for me and all those without a Times subscription), the text of what appears to be the same article has been released to the media by the British Embassy in Beijing. This is presumably because Lord Hunt refers to China.
However, without further comment from me, here is the article in full:
It was the chilliest Easter Day on record, and last month is the coldest March for at least 50 years. But we are not alone in shivering. Across much of Europe, temperatures have been unseasonably cold. In Germany, this has been called a once in a “100-year winter”.
We should not be surprised. It has long been expected that climate change would bring more weird or extreme weather — not just cold but rain, droughts and heat waves — to the UK. So longer spells of colder winter weather are consistent with this. As were drought conditions around this time last year, followed by many months of heavy rain which resulted in the UK experiencing in 2012, the second wettest year on record.
Extreme weather has become more frequent across the world. Australia started 2013 with a record breaking heat wave. Similarly, a heatwave in the US in 2012 (the warmest year on record for mainland America) contributed towards widespread drought which proved devastating for many crops. Russia also experienced its second warmest summer last year. This follows the country’s hottest summer on record in 2010 with states of emergency in seven Russian regions as a result of brush fires, while 28 other regions were put under states of emergency due to crop failures caused by drought.
And then there is the steady increase in peak rainfall rates. These have doubled in South East Asia,for instance over 30 years. It is such a problem that the Malaysians have built a huge SMART tunnel (or Stormwater Management And Road Tunnel) in Kuala Lumpur which doubles up as both a motorway and a six-mile long pipe to cope with flash floods. A similar less pronounced trend is occurring in the UK, which help explains the rise in localised, incredibly heavy showers which have brought flooding from Cumbria to Cornwall. This is caused by a change in the atmosphere called “vertical mixing” in which cumulus clouds become stronger and bigger.
In the UK, the trend is likely to be towards colder winters as a large part of Arctic ice melts permanently (as now happens every summer). The winds over the ice-free ocean could then push colder currents up to Iceland and the Arctic ocean. And as a result of colder waters from the North, the northern UK, in particular, may no longer enjoy the same level of warming from the Gulf Stream as it did when the sea ice boundary was further south.
It is these colder oceans which help to rebut one of the more common arguments used by sceptics to argue that “global warming has stopped”. They often point to graphs which purport to show that Earth’s temperature has not risen in 16 years. But that graph combines land and ocean temperature. Separate the two, and you see that on land temperature is still rising — 0.3℃ over the past decade. More dramatically, in China it has risen by 2℃ over the past 50 years, and 3℃ in the Antarctic over 30 years.
The drop in sea temperature is not just taking place in the Arctic, where the ice is melting, but equally strongly in the eastern Pacific, where winds off the South American coast bring deep, colder waters to the surface. Normally this La Niña phenomenon lasts for three to five years. However, it has been active for more than a decade, caused by easterly trade winds along the equator that have been strengthened by general warming of the atmosphere. When La Niña finally falls away, some time in the next few years, the surface cooling will end. This will increase temperatures over large areas of the globe, disrupting agriculture and fisheries in many countries, and pushing up food prices.
Fortunately, even some sceptics are won round when they experience the problems themselves. The scepticism of some Russian officials has disappeared as they have seen the permafrost melt in the north of the country, and watched the effects of prolonged heatwaves and droughts.
Responsible nations are preparing for the effects of climate change. However, all governments need constant encouragement, in the face of financial austerity and the claims of sceptics, to expand programmes to reduce greenhouse gas emissions.
It is critical they do so, otherwise future generations will have more to worry about than a freezing cold Easter Sunday.
For all those people who have not been duped into believing in the fallacy of the marketplace of ideas, Lord Hunt is someone whose opinions should carry weight. Experts are real and so is anthropogenic climate disruption. So, then, I really do hope that climate change denial will founder on the rocks of reality (and the sooner the better it will be for everybody).
Please do not worry that I am suddenly turning all Evangelical on you. Far from it. I just cannot get over how relevant the following words seem. They were written by former Pharisaic Jew, Saul – known to Christians as St Paul – to his young protegé, Timothy, in 66-67 AD.
But mark this: There will be terrible times in the last days. People will be lovers of themselves, lovers of money, boastful, proud, abusive, disobedient to their parents, ungrateful, unholy, without love, unforgiving, slanderous, without self-control, brutal, not lovers of the good, treacherous, rash, conceited, lovers of pleasure rather than lovers of God… (2 Tim 3: 1-4)
I am trying hard to fend-off a potential Messiah complex with regard to environmentalism but it seems, to me at least, an incontrovertible aspect of modernity that we have now fulfilled this 1950 year-old prophecy. However, as regular readers of this blog may well be able to guess, what concerns me more is that the greatest failure of modernity arose out of the Age of Enlightenment: This seventeenth-Century revolution in natural philosophy meant that Western science emerged from the Dark Ages but, from it, along with all the positive benefits of building on Chinese and Islamic scholarship, we sadly inherited the idea that humans are superior to Nature – rather than part of it. This is a fallacy that underlies the inability of many to accept the reality of ACD (i.e. anthropogenic climate disruption). Either that, or they are deluded into thinking that:
1. Humans are incapable of affecting their environment (despite the precedents of industrial pollution causing Acid Rain and CFCs creating the hole in the Ozone layer); or
2. God will not allow humans to trash the Environment (due to infantile reliance upon things like Genesis 9:15: “I will remember my covenant between me and you and all living creatures of every kind. Never again will the waters become a flood to destroy all life.” Yes, Senator James Inhoffe [R-OK], I am looking at you).
However, as highlighted by Joe Romm on the Think Progress website on 17 March 2013, it is not one that will always be true. With the author’s kind permission, this article, entitled ‘The Dangerous Myth That Climate Change Is Reversible’, is reproduced in full below.
If you have not already read it, I would very much recommend that you do so. However, by way of a summary, here are the key points as I see them:
1. The burning of fossil fuels is causing change that will not be reversible in any timescale meaningful to humans: Although the National Oceanic and Atmospheric Administration (NOAA) say this will be at least 1000 years, the Geological Society of London (GSL) has warned it could take at least 100 times longer than that to undo the damage we are now doing. That being the case, the longer we fail to address this issue the greater the likelihood that the GSL estimate will be correct.
2. Warming will only ever stop if total CO2 emissions are less than the rate of CO2 removal; and one is already twice the other. Any change (current and future) could only be reversed if the CO2 content of the atmosphere were to be reduced (i.e. if removal exceeds emissions). Artificial carbon capture and storage (CCS) is almost certainly impossible to achieve safely, at scale, and within the timescale required (to prevent unstoppable change). That being the case, change is effectively irreversible; and we must stop burning fossil fuels ASAP.
3. Wait and see is no longer a survivable option; we need to decarbonise our power generation systems as fast as possible. Burning all the Earth’s fossil fuels without CCS is very likely to cause unstoppable climate change (i.e. what is called a “runaway greenhouse effect” resulting from feedback mechanisms now observed to be mutually-reinforcing the change human activity has already caused).
Here, then, is Joe’s article in full:
The Dangerous Myth That Climate Change Is Reversible
The CMO (Chief Misinformation Officer) of the climate ignorati, Joe Nocera, has a new piece, “A Real Carbon Solution.” The biggest of its many errors comes in this line:
A reduction of carbon emissions from Chinese power plants would do far more to help reverse climate change than — dare I say it? — blocking the Keystone XL oil pipeline.
Memo to Nocera: As a NOAA-led paper explained 4 years ago, climate change is “largely irreversible for 1000 years.”
This notion that we can reverse climate change by cutting emissions is one of the most commonly held myths — and one of the most dangerous, as explained in this 2007 MIT study, “Understanding Public Complacency About Climate Change: Adults’ mental models of climate change violate conservation of matter.”
The fact is that, as RealClimate has explained, we would need “an immediate cut of around 60 to 70% globally and continued further cuts over time” merely to stabilize atmospheric concentrations of CO2 – and that would still leave us with a radiative imbalance that would lead to “an additional 0.3 to 0.8ºC warming over the 21st Century.” And that assumes no major carbon cycle feedbacks kick in, which seems highly unlikely.
We’d have to drop total global emissions to zero now and for the rest of the century just to lower concentrations enough to stop temperatures from rising. Again, even in this implausible scenario, we still aren’t talking about reversing climate change, just stopping it — or, more technically, stopping the temperature rise. The great ice sheets might well continue to disintegrate, albeit slowly.
This doesn’t mean climate change is unstoppable — only that we are stuck with whatever climate change we cause before we get desperate and go all WWII on emissions. That’s why delay is so dangerous and immoral. For instance, if we don’t act quickly, we are likely to be stuck with permanent Dust Bowls in the Southwest and around the globe. I’ll discuss the irreversibility myth further below the jump.
First, though, Nocera’s piece has many other pieces of misinformation. He leaves people with the impression that coal with carbon capture and storage (CCS) is a practical, affordable means of reducing emissions from existing power plants that will be available soon. In fact, most demonstration projects around the world have been shut down, the technology Nocera focuses on would not work on the vast majority of existing coal plants, and CCS is going to be incredibly expensive compared to other low-carbon technologies — see Harvard stunner: “Realistic” first-generation CCS costs a whopping $150 per ton of CO2 (20 cents per kWh)! And that’s in the unlikely event it proves to be practical, permanent, and verifiable (see “Feasibility, Permanence and Safety Issues Remain Unresolved”).
Heck, the guy who debated me on The Economist‘s website conceded things are going very slowly, writing “The idea is that CCS then becomes a commercial reality and begins to make deep cuts in emissions during the 2030s.” And he’s a CCS advocate!!
Of course, we simply don’t have until the 2030s to wait for deep cuts in emissions. No wonder people who misunderstand the irreversible nature of climate change, like Nocera, tend to be far more complacent about emissions reductions than those who understand climate science.
The point of Nocera’s piece seems to be to mock Bill McKibben for opposing the idea of using captured carbon for enhanced oil recovery (EOR): “his answer suggests that his crusade has blinded him to the real problem.”
It is Nocera who has been blinded. He explains in the piece:
Using carbon emissions to recover previously ungettable oil has the potential to unlock vast untapped American reserves. Last year, ExxonMobil reportedthat enhanced oil recovery would allow it to extend the life of a single oil field in West Texas by 20 years.
McKibben’s effort to stop the Keystone XL pipeline is based on the fact that we have to leave the vast majority of carbon in the ground. Sure, it wouldn’t matter if you built one coal CCS plant and used that for EOR. But we need a staggering amount of CCS, as Vaclav Smil explained in “Energy at the Crossroads“:
“Sequestering a mere 1/10 of today’s global CO2 emissions (less than 3 Gt CO2) would thus call for putting in place an industry that would have to force underground every year the volume of compressed gas larger than or (with higher compression) equal to the volume of crude oil extracted globally by [the] petroleum industry whose infrastructures and capacities have been put in place over a century of development. Needless to say, such a technical feat could not be accomplished within a single generation.”
D’oh! What precisely would be the point of “sequestering” all that CO2 to extract previously “ungettable oil” whose emissions, when burned, would just about equal the CO2 that you supposedly sequestered?
Remember, we have to get total global emissions of CO2 to near zero just to stop temperatures from continuing their inexorable march toward humanity’s self-destruction. And yes, this ain’t easy. But it is impossible if we don’t start slashing emissions soon and stop opening up vast new sources of carbon.
For those who are confused on this point, I recommend reading the entire MIT study, whose lead author is John Sterman. Here is the abstract:
Public attitudes about climate change reveal a contradiction. Surveys show most Americans believe climate change poses serious risks but also that reductions in greenhouse gas (GHG) emissions sufficient to stabilize atmospheric GHG concentrations or net radiative forcing can be deferred until there is greater evidence that climate change is harmful. US policymakers likewise argue it is prudent to wait and see whether climate change will cause substantial economic harm before undertaking policies to reduce emissions.Such wait-and-see policies erroneously presume climate change can be reversed quickly should harm become evident, underestimating substantial delays in the climate’s response to anthropogenic forcing. We report experiments with highly educated adults–graduate students at MIT–showing widespread misunderstanding of the fundamental stock and flow relationships, including mass balance principles, that lead to long response delays. GHG emissions are now about twice the rate of GHG removal from the atmosphere.
GHG concentrations will therefore continue to rise even if emissions fall, stabilizing only when emissions equal removal. In contrast, results show most subjects believe atmospheric GHG concentrations can be stabilized while emissions into the atmosphere continuously exceed the removal of GHGs from it. These beliefs-analogous to arguing a bathtub filled faster than it drains will never overflow-support wait-and-see policies but violate conservation of matter. Low public support for mitigation policies may be based more on misconceptions of climate dynamics than high discount rates or uncertainty about the risks of harmful climate change.
Again, zero emissions merely stops climate change, and obviously, thanks to fossil-fuel funded Tea Party politicians along with the deniers and the ignorati, we won’t be going to zero anytime soon.
Finally, I recommend RealClimate’s 2009 post, “Irreversible Does Not Mean Unstoppable“:
But you have to remember that the climate changes so far, both observed and committed to, are minor compared with the business-as-usual forecast for the end of the century. It’s further emissions we need to worry about. Climate change is like a ratchet, which we wind up by releasing CO2. Once we turn the crank, there’s no easy turning back to the natural climate. But we can still decide to stop turning the crank, and the sooner the better.
Indeed, we are only committed to about 2°C total warming so far, which is a probably manageable — and even more probably, if we did keep CO2 concentrations from peaking below 450 ppm, the small amount of CO2 we are likely to be able to remove from the atmosphere this century could well take us below the danger zone.
But if we don’t reverse emissions trends soon, we will at least double and probably triple that temperature rise, most likely negating any practical strategy to undo the impacts for hundreds of years.
With my thanks once again to Joe Romm, for permission to republish the above, all that remains for me now is to wish you all a pleasant [Passover/Easter/Spring Equinox] festival of renewal!
With my thanks to 350.org for alerting me to this piece of news:
As reported in the Washington Post newspaper recently, UN Secretary-General Ban Ki-moon is warning that by 2030 nearly half the world’s population could be facing a scarcity of water, with demand outstripping supply by 40 percent.
For those of us in the grip of unseasonally cold weather this may seem hard to grasp but, this is where we are heading. However, even without climate change, providing enough water for everybody would be difficult. Climate change will just make it near impossible.
…The Sunday Telegraph starts advocating polices that will accelerate anthropogenic climate disruption (ACD).
Two days ago, one of Britain’s oldest and most-respected broadsheet newspapers decided to shred the last few bits of credibility it might have had by publishing an anonymous editorial piece calling for the Climate Change Act 2008 to be repealed.
I am therefore sorry but, I just had to post this response:
Thank goodness the Sunday Telegraph is not a widely-read newspaper. This kind of advocacy for policies that will accelerate anthropogenic climate disruption is short-sighted to say the least.
If you don’t like our countryside being despoiled by windfarms, new sets of National Grid power lines, and new nuclear plants… What you should be advocating is greater subsidies for households that install solar PV panels on their roofs, which will reduce UK demand for centrally-generated electricity of all kinds.
Oh and, by the way, shale gas is not low-carbon intensity: Because of the methane release it involves, it is extremely high-carbon intensity. Now we know we need to reduce our global CO2 emissions and that further delay will mean greater ultimate cost (i.e. Sir John Beddington, today)… the international push to extract shale gas – and all other unconventional hydrocarbons – is completely irrational.
If anyone is curious, the pronouncements of the UK Government’s Chief Scientist, Sir John Beddington, to which I referred above, can be seen and heard in this video on the BBC website. This was a fascinating development, coming, as it did, on the same day that the Global Warming Policy Foundation (GWPF) announced that it was willing to enter into discussions with the Royal Society – to try and resolve the fact that the two organisations hold diametrically-opposed views regarding the validity of the scientific consensus that ACD is already happening.
This prompted me to send the GWPF’s Director, social anthropologist Benny Peiser, the following email:
Dear Dr Peiser,
I note, with genuine interest, your acceptance of the offer by the Royal Society to put the GWPF in touch with mainstream climate scientists.
I note also the public statement by the Sir John Beddington – who says evidence of anthropogenic climate disruption is now unequivocal and further delay in reducing emissions will mean harder and more expensive policy changes in future.
I should therefore be very grateful to know how much longer you think the GWPF is going to continue to insist that the science is uncertain and that calls for action are politically motivated. For example, how long will it be before the GWPF accepts that we need to decarbonise our power generation systems – by implementing a revenue-neutral Fee and Dividend system as proposed by Dr James Hansen and many others.
Yours very sincerely,
No answer as yet.
Dear George Osborne, Chancellor Merkel, EU Commission, Citizens of Cyprus, and people everywhere,
Please accept my condolences for your loss(es) and my sincerest wish that you will now stop lying to yourselves; and face-up to the nature of reality.
Further to the comment by Lionel Smith (below), this is what page 159 of Stephen Hawking’s The Universe in a Nutshell looks like:
This is the problem that we have with exponential growth.
For ease of reference, however, here is the relevant part of that quotation once again:
…Know that this culture of self-worship and materialism is sending our species to the dustbin of failed evolutionary experiments, most certainly by the end of this century if not mid-century. The evidence is all around us if only we care to open our eyes.
So, then, what are these “failed evolutionary experiments”; and why might we be about to join them in the dustbin? Indeed, what does it mean to suggest there is a dustbin? I ask this latter question because, as I often seem to find myself saying, the concept of waste disposal is an illusion: Nature does not do waste disposal; it only ever does recycling.
However, there is an even more fundamentally-challenging aspect to xraymike79’s turn of phrase, which is the suggestion that the emergence of complex life on Earth is the result of an unguided process. Jean-Paul Sartre’s question “Why is it that there something rather than nothing?” is answered with the following equation: Nothing + Time + Chance = Something.
Some scientists, such as George Smoot (Wrinkles in Time) and Paul Davies (The Mind of God) have asserted that the Universe appears to be perfectly designed to accommodate us – effectively a statement of the Anthropic Principle. However, I find it hard to refute the argument, made by people like Richard Dawkins and Stephen Hawking, that we are here because the Universe is the way it is – effectively a statement of existential Selection Bias.
For people of a theistic persuasion (like me for example), such notions are very challenging. However, I dislike the arrogance of people like Dawkins and Hawking, who – rather than just assert that they do not believe in God – appear to want to insist that they have proven that God does not exist. Although they present cogent arguments and justifications for their atheism, I prefer the position adopted by Stephen J. Gould – that science and religion represent non-overlapping magesteria. This is the proposition that science seeks to answer “how” questions, whereas religion seeks to answer “why” questions. If so, it would appear to be self-evident that trouble ensues when either party steps outside the boundaries of their legitimate enquiry.
It was for this reason that Young Earth Creationism had been rejected by the vast majority of Christian theologians even before Charles Darwin was born. They had, in essence, followed the advice of St Augustine (354-430AD) in The Literal Meaning of Genesis, and Thomas Aquinas (1225-74AD) in Summa Theologica. For example:
Holy Scripture can be explained in a multiplicity of senses, [and] one should adhere to a particular explanation only in such measure as to be ready to abandon it if it be proved with certainty to be false, lest Holy Scripture be exposed to the ridicule of unbelievers, and obstacles be placed to their believing… (Thomas Aquinas, 1273AD)
As I said to my son recently, “just as scientific theories like evolution should not be used to reject religious beliefs; Biblical texts should not be used to reject scientific facts”. I hope you will agree that this is a nice turn of phrase too, but, it belies the fact that all knowledge in science is provisional. However, in my defence, I must protest that “should not be used to reject things most scientists consider to be beyond reasonable doubt” …does not sound quite so good.
So then, back to big question: Is evolution a random process with no pre-ordained purpose; or has it been guided by someone or something? Well, I think I am going to dodge the bullet on that one; but I will say this: I was astonished recently to learn about the ‘Maximum Power Principle’ – as proposed by Howard T. Odum – that suggests that Darwinian-style natural selection tends to produce organisms “that maximize power intake, energy transformation, and those uses that reinforce production and efficiency”. For background to this, please see this comment (and those that follow it) by Paul Chefurka on Guy McPherson’s Nature Bats Last blog.
If you look at Chefurka’s comments, you will see that he blames the ‘Maximum Power Principle’ for the fact that humanity seems set on a path to self-destruction (and unintended ecocide), i.e. that our consumption of resources is biologically-driven. Some may say, as I did initially, that this explains an awful lot but, upon further reflection, I am inclined to think that this could be used as an abdication of ultimate responsibility for our not leaving this Earth in as good a state as we were fortunate enough to find it.
Be that as it may, the evidence from the fossil record suggests that the vast majority of species that have ever lived are probably no longer with us today. However, that does not make them “failed evolutionary experiments”. Indeed, I would argue that some species that have survived through to the present time look like failed evolutionary experiments (and I do not mean humans). What sense is there in that? Why do some species appear to have got stuck in a time-warp? Is it enough just to say they are adapted to their niche environments?
I am therefore ambivalent about the question of whether evolution must be seen as purposeful or self-selecting process. However, I think xraymike79’s turn of phrase is useful because it has the potential to shake us from our anthropocentric complacency. Furthermore, I think it almost demands that – instead – we embrace the ecocentric reality around us: Apart from a few dairy cows that might experience some significant discomfort for a while – most of life on Earth would not even notice if we humans disappeared. As Edward O. Wilson observed, we may be the most intelligent life form on Earth – and we may be at the top of every conceivable food chain – but humans are not the most important life form on Earth. That honour probably goes to fungi – Nature’s most effective and efficient recyclers.
Unfortunately, we humans seem determined to go down fighting and, unless we wake up to the reality that we cannot subdue and dominate Nature – we must seek to live in harmony with it – it seems increasing likely that we will cause the widespread breakdown of many essential ecosystem services upon which all life on Earth depends. This is because we are currently in the process of deconstructing the benign and stable environment that has made life possible. As such, the Hockey Stick may have now turned into a Scythe:
That being the case, we must all hope this does not herald the arrival of the Grim Reaper himself. :-(
* “Sustainable Growth” is a term invented by World Leaders last year at the Rio+20 Summit in Brazil. On a finite planet with finite resources, it is a physical impossibility; it is an oxymoron; to talk about it is as delusional as pretending you will live for ever. I’m sorry, but, as with climate change, denying the nature of reality changes nothing.
As an experienced geologist and hydrogeologist, I am a Fellow of the Geological Society of London (GSL) and a Member of the Chartered Institution of Water and Environmental Management (CIWEM). As such, the GSL has previously published a 500-word “soapbox” item written by me, entitled ‘Know Your Limits!’, in their Geoscientist magazine.
However, I believe this has now been surpassed by an article written by CIWEM’s Executive Director, Nick Reeves, just published in CIWEM’s monthly WEM magazine. Having obtained the permission of both author and publisher, I am delighted to reproduce the article, entitled ‘The Growth Delusion and Handlebar Tape’, in full below.
Other than to say that Nick Reeves has an admirable track-record for speaking his mind and saying things very few people in positions like his are willing to say – such as his support for Latin American style environmentalism in ‘The Human Rights of Mother Earth’ (July 2011) – I do not really want to comment further at this point. However, the conflict between notions of sustainable development and resource depletion will be picked-up in another longer-than-normal post later this week. Therefore, without further ado, here is the 1800-word article by Nick Reeves:
The world is running on empty says CIWEM executive director Nick Reeves
How do you successfully break a mistaken and destructive intellectual and economic consensus? How do you persuade world leaders that 21st century problems cannot be fixed with 20th century economics?
The UK is no longer a front-line developed nation and has fallen behind Brazil in the league table of economic powers. It will take a lot more than handlebar tape to get a grip on things. We need to think in different terms and get a proper fix on our place in a world that is running on empty.
The economic crisis of 2007 was a car crash in slow-motion. The driver wasn’t fit. And it was frustrating because nobody warned us and the banks danced to the speculative tune. Now economists can calculate a much more dangerous event that is being greeted with even less concern: our world is rapidly running out of resources – of water, energy, metals, phosphorous and food. The data is not in dispute. The market is reflecting what our leaders ignore.
The Industrial Revolution allowed us to make technological progress in delivering resources, outweighing the increasing marginal effort to dig ever deeper and chase lower-quality ores, for instance. The average price of 33 commodities (equally weighted) declined by 70 per cent (after inflation) between 1900 and 2002. Then, abruptly and without any particular crisis, prices reversed and in ten years the average commodity tripled to give back the advantage of the previous 100 years. It is perhaps the most important ‘phase’ change of modern times, yet it attracted, remarkably, little attention or concern.
The causes are not hidden: there has been an explosion in population and consumption since 1800 and the birth of the ‘Hydrocarbon Age’. Global population has increased from one billion to seven billion, tripling even in my lifetime. At the same time, consumption of hydrocarbons and some metals increased one hundredfold. Initially, with few people and extensive high-grade resources, this did not show in prices, but more recently, with population growing still faster than ever in absolute terms, we have had to absorb an unprecedented surge in demand per capita from India, with its 1.2 billion people (growing at over seven per cent a year) and China, with almost 1.3 billion (growing for over 20 years at ten per cent a year), a rate that will double consumption every seven years. China last year accounted for a jaw-dropping 53 per cent of the world’s cement use, 48 per cent of its iron ore and 47 per cent of all the coal used. How could reserves not wither away under this attack and prices not rise? We have every reason to be fearful.
Low-cost, high-grade coal, oil and natural gas – the backbone of the Industrial Revolution – will be a distant memory by 2050. Much higher cost remnants will still be available but they will not be able to drive our growth, our population and, most critically, our food supply, as before. Conventional food production is dependent desperately on oil for insecticide, pesticide and fertiliser, and for transportation over thousands of miles. Modern agriculture is an industry that converts oil into food.
It will require brave political decisions to survive the loss of depleted hydrocarbons without risking economic collapse. If we permit the population to grow to the levels predicted, and if we don’t curb our greed, we must find the capital – while we still have it – to build very large-scale, very smart electricity grids, across Europe and North America, fed by increasingly efficient wind and solar power and other renewables that may come on stream.
Once they are built, the marginal operating cost will be much lower than our present hydrocarbon-dependent system and, critically, cost will be constantly falling while hydrocarbon costs rise. This will be a great threat to the giant hydrocarbon multi-nationals, several of which fund well-organised obfuscation and propaganda campaigns to reinforce our wishful thinking. Carbon dioxide has lost its greenhouse effect, they say, and coal is clean! In the US, even larger investments are made: Congress is bribed (legally) to ignore both climate science and the logic of finite resources.
Metal resources are the stuff of nightmares because entropy is merciless. Every time you use a metal, some is lost. European countries recycle between 40 per cent and 80 per cent – the US is worse – yet at even 90 per cent these precious resources will slip through our fingers. So frugality is needed, because even an economy with zero increase in physical output will slowly lose its metals. But which politician has the nerve to talk about the necessary zero growth in population and physical output?
The most immediately threatening shortage is in our food supply, and not just from oil constraints. The bigger threats lie in four limiting inputs: water, soil, potassium and phosphorus. We build homes and grow food in deserts and over-pump irreplaceable underground water. (Already, about 300 million Indians and Chinese, among others, are fed by over-pumping reserves that will inevitably run out.) We waste over half our global water supply and we totally mis-price it. For most countries, all of this can be fixed. Yet some over-populated, poor nations have a more intractable problem and water scarcity will cause increasing friction for them. Water wars is here. It’s happening now.
Land availability and erosion are also limiting our ability to grow food. Over the millennia, we have lost about one-third of our land, turning it into desert and stone. We build new cities on our best river valley soil, which is replaceable only with more marginal land. There are no New Worlds or new Midwests. The land we have – eroded by wind and water – loses one per cent of its soil each year, about 100 times the rate of natural replacement. If sustained, this erosion would bring our species to its knees. But the problem can be solved relatively easily by moving towards no-till, in which crop residues protect the soil against the elements. We need to move rapidly, though: to 100 per cent from less than ten per cent, globally, today.
The limits on phosphorous and potassium are terminal potentially. They are elements and cannot be made. There is no substitute for them. They are vital for the growth of all living things, vegetable or animal (we humans are one per cent phosphorus by body weight). And these irreplaceable nutrients on which modern agriculture depends are mined and are steadily depleting. So what will happen when the reserves run out?
The only glimmer of hope would be if the world went organic – nurturing the soil with worms, fungi and complex micro-organisms and avoiding use of pesticides and insecticides. Organic farming extends critical fertiliser resources many times, perhaps at best approaching the rate of natural replacement from bedrock. However, organic farming is just one per cent of the agricultural total, and we will, typically, wait for a greater crisis in fertiliser prices before we move.
Finally, global warming’s most reliable consequence is weather extremes – droughts and floods, which have badly hit production, will continue to do so. Far from being alarmist, scientists have consistently under-predicted the speed of environmental decline, failed to address population growth, and so we slalom our way to hell. Scientists, with a few brave exceptions, are fearful of being criticised as doom-sayers and exaggerators – a terrible academic crime – even though underestimating, in this case, is far more dangerous and irresponsible. (Arctic ice-melt is already at levels that, 15 years ago, were predicted for 2050.)
Both population and yield per acre for grains are growing at 1.2 per cent a year. A stand-off? You bet. Population growth will slow, but so will productivity as we approach the limits of each grain species. How, with no safety margin, will we find the extra grain necessary to produce meat for the growing middle class of developing nations when a single pound of dressed beef displaces 30 pounds of grain?
There will be a single painful answer to all of these questions – rationing through price. We the rich nations can and will be careless with our resources for decades longer, but only at the cost of pushing prices up unnecessarily fast and thereby inadvertently forcing the poor into malnutrition and outright starvation. A typical developed country now spends ten per cent of its income on food; Egypt spends 40 per cent. You can see easily that, if food prices triple again in the next 30 years as they did in the past ten, the numbers will not compute. A growth-reducing and lifestyle-eroding irritant for us will become life and death for them.
Greater income equality in such countries and better education, especially for women, would help lower population growth and increase productivity. Less corruption and more efficient distribution of the food available, especially in India, would buy decades of time. But this is who we are: a species given to corruption, incompetence and self-interest. Capitalism sucks because it believes that its remit is exclusively to make maximum short-term profits – come hell or high water.
We could solve all our problems if only we were the efficient, rational human beings of standard economic theory and had politicians willing to think in the long-term interest of their people rather than their own. Perhaps later, as the crisis grows, as failing states threaten to destabilise global politics (resource pricing already played its part in the Arab spring) and China throws its increasing weight around in its correctly perceived great need for more resources, the developed world will act with resolve, as the US, the UK and others did so well in the World War II. We must hope so.
Fortress North America with (per capita) five times the water and seven times the arable land of China, has the capability and willingness to ignore this global problem for now. Yet eventually it, too, will be dragged kicking and screaming into world turmoil – just as it feared would happen in the 1930s – and share the pain.
In the meantime, countries such as Egypt, with surging populations, escalating food import bills and widening trade deficits, cannot afford to feed their people. Who will do it for them? We rich countries cannot even make the tough political decisions required to keep our own resource prices down, let alone worry about others. This attitude is epitomised by the use of one-third of the US corn crop (the world’s biggest) for desperately inefficient ethanol production as a subsidy for already rich farmers. To fill a 4×4′s tank once would displace enough maize to feed one Indian farmer for a year. One day, this will be seen as the moral equivalent of shooting some of the world’s poorest people, but more painful.
