Uncertainties about the effects of fracking in the UK
I’m a bit of an energy agnostic. This week I attended a talk at UWE about fracking and its impact on the environment in the hope of making a better informed decision on the controversial topic.
What is fracking?
Jenna Brown, a first year PhD student, started off with an introduction to fracking, or hydraulic fracturing.
Gas molecules trapped in dense shale rocks are almost impossible to obtain by normal drilling. Fracking involves drilling vertically down and then horizontally into the rock. Fracking fluid, a mixture of water, sand and other chemicals, is injected into the rock at high pressure, expanding the tiny cracks and allowing the gas trapped within to escape and travel back up the pipe for collection.

Environmental uncertainty: A challenge to both business and vulnerable communities
In September, the IPCC published the Fifth Annual Report on the Physical Basis of Climate Change. It devotes little attention to the human and ecological impacts of global environmental and climatic change, topics that will be addressed by working group reports released in early 2014 . Nonetheless, the trajectory of climate and other environmental changes and their implicit impacts on society are stark. Despite numerous treaties and efforts at mitigation, concentrations of carbon dioxide and other greenhouse gases continue to increase, and at greater rather than diminished rates. If those rates continue they will result in global warming of 3 to 5.5°C by 2100. This in turn, will result in dramatic changes to the global hydrological cycle, including both more evaporation and more rainfall.
A More Uncertain Climate
![]() |
Flood by Paul Bates |
The results will be a more hostile climate for many as land can become either drier or more flood-prone or both, changes exacerbated in coastal areas by sea level rise. Freshwater supply will also be affected by the forecast changes in climate. The quantity of water flowing in glacier or snow-melt fed river basins will change, affecting around a sixth of the world’s population[i], while coastal freshwater will be contaminated with saline water[ii]. Areas of the Mediterranean[iii], Western USA[iv], Southern Africa[v] and North Western Brazil[vi] are projected to face decreased availability of freshwater.
Key to understanding who will be affected is our ability to predict changes in rainfall, seasonality, and temperature at a regional scale. However, regional climatic predictions are the most challenging and least certain, especially with respect to the nature and amount of rainfall. For vast parts of the world, including much of South America, Africa and SE Asia, it is unclear whether climate change will bring about wetter or drier conditions. Thus, uncertainty will become the norm: uncertainty in rainfall; uncertainty in weather extremes and seasonality; and most importantly, uncertainty in water resources.
Those combined effects lead to an additional and perhaps the most profound uncertainty for the latter half of the 21st century: uncertainty in food production and access. In the absence of other factors, climate uncertainty and more common extreme events will compromise agriculture at all scales, yielding increased food prices and increased volatility in markets.
Impacts on the Poor
Although the human impacts of climate change will be diverse, their effects will be worst for the most impoverished and, by extension, least resilient population groups. The UN reports that climate change could “increase global malnutrition by up to 25% by 2080.” And all of this occurs against a backdrop in which access to food is already a challenge for the poorest of the world already a challenge for the poorest of the world [p5], a situation exacerbated by the global financial crash.
These risks to the poorest result from a lack of resources to mitigate harm, lack of power to protect resources, and the global competition for resources.
Those who lack the financial resources to migrate or build more hazard-resistant homes will suffer most from extreme events, as has been sharply illustrated by those suffering most in the aftermath of Typhoon Haiyan. Those who can least afford to dig deeper wells into more ancient aquifers as water resources diminish will go thirsty. Subsistence farmers – and those dependent on them – are less resistant to climate shocks (desertification) and adverse weather events (flooding) than commercial farmers.
Land ownership for the poorest is often tenuous, and displacement from land a serious problem for many. Previous switches to biofuels have led to land competition, resulting in both loss of land to subsistence [p6] farmers, and diversion of commercial production leading to shortages [p7] and increased food prices. Within communities, these effects are not evenly spread as marginalised groups, such as women, are the least likely to hold land tenure [p8] . Similarly, there is increased competition for water [p9] between peoples, but also between water for industry (including agriculture) and water for drinking. When water is scarce, pollution of fresh water is common, and governance is weak, the poorest are likely to lose out.

Food competition will most likely be exacerbated by other factors: rising demand from a rapidly expanding population and a growing demand for meat from a global ‘middle class’; the increased economic divide between post-industrial and developing nations; the ongoing depletion of soil nutrients and associated impacts on the nutritional value of our food. The combination of these factors will result in profound impacts on food security. Who decides what gets grown? Who can afford it in the context of global markets and the loss of agricultural land? The poorest members of even the wealthiest societies are the most vulnerable to dramatic and unpredictable changes in food costs[p10] .
‘Wicked Problems’
These issues yield a profoundly challenging ethical issue: the wealthy who are most responsible for anthropogenic climate change, via the greatest material consumption and energy demand, have the greatest resilience to food market fluctuations and the greatest means for avoiding their most deleterious impacts. Therefore, these issues challenge all governments to dramatically and swiftly act to decrease greenhouse gas emissions and mitigate the associated climate change.
Unfortunately, many proposed mitigation strategies could also have negative consequences for food prices and availability. Increasing energy prices, such as those brought about by a carbon tax, will be passed onto food prices. Genetically modified foods could be essential to feeding a growing population, and we would urge that future efforts expand to incorporate a greater degree of climate resilience in crops; however, the patents on those crops can make them financially inaccessible to the poorest nations or build critical dependencies.
Although sustainable agriculture and crops might reduce the impact of climate change and uncertainty in some countries, these solutions can be deleterious for the poorest. They are more likely to live in regions and areas most negatively affected by climate change, most likely to be relying on subsistence/small scale agriculture and least likely to have access to the global market as consumers. In other words, a stable global market will be of little direct benefit to them; in fact, most of these populations are likely to face competition for land/water use from globalised markets (for biofuels or commercial farming). In short, what builds food resilience in one nation might be exposing the most economically vulnerable in another.
In fact, when properly mobilised for the benefit of the community, access to new energy sources – even if in the form of fossil fuels – can be transformative and facilitate the economic growth needed to access increasingly globalised food markets [p12]. Domestic access to gas reduces the need to collect wood for fires, reducing deforestation, improving air quality, and freeing up time for communities to address other development needs.
This is not an argument against mitigation of climate change, but it does need to be balanced against human development needs; and this represents one of the world’s most profound challenges. In some circles, we consider this a ‘wicked’ problem: a problem that has multiple causes, probably in interaction, and where information is incomplete, such that proposed solutions might be incomplete, contradictory, complex and work across multiple causes in complex systems.
Challenges and Opportunities
![]() |
Biofuel by La Jolla |
Wicked problems are not intractable, however, and previous studies of land use for biofuels provide clues as to how a complex solution could be more sustainable for all; well planned switches to biofuels which consider local custom in land tenure can provide more land for agriculture, and reduce deforestation pressure.
In such situations, we argue, solutions which focus on halting or slowing climate change alone, and then coping with the business and development problems that they might create answer the wrong question. Our challenge to the business (and academic) community, then, is to engage with some wicked questions:
- What are the business opportunities in improving the social and physical environment?
- Can the global agricultural system be a single resilient network, rather than a competition?
- What technology or innovation is needed to support a resilient food network?
- How can innovative solutions to these challenges generate local income, allowing reinvestment in education and development?
These are difficult questions but they also represent opportunities for development and growth in poor communities. A world with increasing environmental uncertainty is a challenge for both businesses and vulnerable communities. But it could also be a shared opportunity for growth and development: to innovate and identify new solutions, to co-invest in local resilience and risk reduction, and to share the growth that arises from more stable communities.

Nine lessons and carols in communicating climate uncertainty
About a month ago I was invited to represent the Cabot Institute at the All Parliamentary Party Climate Change Group (APPCCG) meeting on “Communicating Risk and Uncertainty around Climate Change”. All Party Groups are groups of MPs and Lords with a common interest they wish to discuss, who meet regularly but fairly informally. Here are the APPCCG register, blog, Twitter and list of events.
The speakers were James Painter (University of Oxford), Chris Rapley (UCL) and Fiona Harvey (The Guardian), and the chair was (Lord) Julian Hunt (UCL). Rather than write up my meeting notes, I’ll focus on the key points.
[Disclaimer: All quotes and attributions are based on my recollections and note-taking, and may not be exact.]
Lessons: We cannot expect or ask people to worry about everything: concern about other issues can reduce concern about climate change, while evoking strong emotions about climate change can reduce concern about other issues. So Chris encouraged talking about opportunities, rather than threats, wherever possible.
2. People interpret uncertainty as ignorance
People often interpret the word “uncertainty” as complete ignorance, rather than, for example, partial ignorance(..!) or a well-defined range of possible outcomes. This may be due to language: “I’m not certain” is close to “I don’t know”.
Just as important is exposure to research science. Science is often presented as a book of facts, when in fact it is a messy process of reducing our uncertainty about the world. At a school this year the head teacher told us about an Ofsted inspection during which they had a fantastic science workshop, where groups of students solved challenging problems using real data. At the end of the day, the inspector said: “Fine, but wouldn’t it have been quicker to have told them the answer first?”
Lessons: Revolutionise the education system.
“The Higgs boson”, Chris said, “was not a ball bearing found down the back of sofa, but a statistical result”. It was just possible it hadn’t been discovered. But it wasn’t reported this way. The Higgs, of course, does not invoke fear, anxiety or political disagreement (though please leave comments below if you disagree).
Lessons: Decision paralysis might be reduced by talking in terms of confidence rather than uncertainty. But perhaps more importantly…
Lessons: Where possible, talk in terms of risk not uncertainty; see for example the IPCC report on extreme weather and, naturally, our book Risk and Uncertainty Assessment for Natural Hazards.
He also pointed out that we don’t have training in how to deal with the “street fight” of the climate debate. In my experience, this is one of the two main reasons why most of my colleagues do not do public engagement (the other being time commitment).
Lessons: For communicating uncertainty and risk, I recommend UnderstandingUncertainty.org. For dealing with the street fight, my advice is first to start with a lot of listening, not talking, to get a feel for the landscape. And to talk to climate scientists already engaging on how to avoid and deal with conflict (if, indeed, they are avoiding or dealing with conflict…).
The IPCC assessment reports use a “language” of uncertainty, where phrases such as “extremely likely” are given a specific meaning (in this case, 95% or greater likelihood). But James said that only 15% of media articles about this year’s report explained the meaning of this uncertainty language.
And in the discussion someone quoted a journalist as saying “The IPCC report says it has 95% confidence – what do the other 5% of the scientists think?” In other words, confusing the idea of a consensus and a confidence interval. There was a laugh at this in the room. But I think this is easily done by people who do not spend all day thinking about statistics. That would be: the majority of the human race.
Lessons: Er, many journalists could benefit from more statistical training. Here is what that might look like.
Fiona, her tongue only slightly in cheek, gave us this memorably-made and disappointing (if predictable) point.
Just because something is important it doesn’t mean it will get into a news outlet. An editor might go to a cocktail party, talk to their glamorous celebrity friends, hear some current opinion, and then the next day their paper says…
In other words, the social diary – including meetings with high profile climate sceptics – can have a substantial influence on the viewpoint taken. (Of course, she noted, the editor of The Guardian is a profound man, not influenced by such superficiality). To counter this we would need to go to influential people and whisper in their ears too. We would need to launch a prawn cocktail offensive – or more appropriately, as one wit suggested, a goats cheese offensive. You heard it here first. And last.
Lessons: Go to more cocktail parties hosted by influential people.
There was generally support of scepticism by the speakers. Chris said it was perfectly valid for the public to ask scientists “Can we see your working?”; in other words, to ask for more details, code and data. All the speakers said they don’t use the word “denier”.
James said we should not generalise, and described four types of sceptic: trend, attribution, impacts, and policy. A trend sceptic would not be convinced there is global warming; an attribution sceptic about how much is man-made; an impacts sceptic might say we don’t know enough about when and how severe the impacts will be; and a policy sceptic would take issue with how to tackle the problem. (Personally, I believe there are as many types of sceptic as there are sceptics, but that would be a longer list to write down). Fiona pointed out that one person can be all these types of sceptic, moving from one argument to another as a discussion progresses. Some thought this would be incoherent (i.e. kettle logic, contradictory arguments) but others thought it could be coherent to be sceptical for more than one of those reasons.
Lessons: Treat each sceptic as an individual (flower); don’t assume they are one type of sceptic when they may be another, or more than one.
All this is true. But I’ll end with a slightly more optimistic quote, which I think was from Chris: “The sea change in the battle with tobacco companies was when the message got across that the adverts were not trustworthy.” I quote this not because I believe it is the same as the climate debate, and not because sceptics are untrustworthy (though some may be), but because I (some might say, choose to) interpret it to mean that trust is important. When people trust the messenger, the message is more likely believed.
Lessons: Other things are important, but sometimes communication is a matter of trust. I emphasise this point because it’s what I already believe; others may disagree (politely, please…).
I would have liked to add more references supporting the points made by the speakers, but ran out of time. Some are in James’ book mentioned above. Do please add them in the comments if you have them.
The title of this blogpost came from realising I had nine points to make and thinking of this set of shows curated by Robin Ince celebrating science, skepticism, and rationalism. If you’re in the UK this December, do go.
My week in Westminster: Part 2
Wednesday 4 December 2013

Alan Pitt |
After two days of being in the ‘classroom’ learning about science in Parliament and Government it was time to go and shadow my civil servant, Alan Pitt, the Secretary to the Council for Science and Technology (S&T) who advise the Prime Minister directly on science related issues. Alan is based in the Government Office for Science (Go-Science), which is located in the Department for Business, Innovation and Skills! My morning began by visiting Portcullis House to hear the Government Chief Scientific Advisor, Sir Mark Walport, be quizzed by the House of Commons S&T Select Committee, which consists of cross-party MPs. Their job is to scrutinise Government on S&T to ensure the policy making process is robust. Mark Walport, gave an overview of his vision for Science in the UK which included infrastructure in terms of energy and climate, qualitative and quantitative scientific evidence used in Government and a prominent leadership role for science. This session was followed by an inquiry on Horizon Scanning including what this entails and how it operates!
![]() |
Sir Mark Walport |
Next stop was BIS where I was introduced to various members of Go-Science who explained their roles as civil servants including defence and resilience, coordinating all the different scientific committees, groups etc. I learnt about the complexity of science organisation in the civil service. For example, every department bar one has a Chief Scientific Advisor and a team beneath them. They report to Ministers who report to the Prime Minister.
Alan was particularly busy organising the CST quarterly meeting to be held at the Royal Society! Mid-afternoon I went with him over to the Royal Society building to help set up for the evening meeting and dinner. The CST consists of members appointed by the Prime Minister who have extremely impressive credentials. Chaired by the Government Chief Scientific Advisor, other members include Vice Chancellors, the President of the Royal Society, and prominent scientists in business.
After a busy but thoroughly enjoyable day it was time to go and see a show in the West-End!
Thursday 5 December 2013
On my final day of shadowing I was lucky enough to be able to sit on the CST meeting and hear what they get to discuss and consequently some of the content that goes into a letter directly written for the Prime Minister! It was a fascinating if little surreal experience! I finished my time in London by having a tour of the Royal Society with the opportunity to see the original scribblings of Isaac Newton and Robert Hooke.
The Royal Society Pairing scheme has been an action-packed and fun experience and a real eye-opener to how science is used in Parliament and Government. Everything is far more scrutinised then I ever envisaged and I hope that the scheme will help to enhance this process by building relationships between the policy makers and the scientists.

My week in Westminster – Part 1
Monday 2 December 2013
36 scientists were up bright and early in London for a tour around the Palace of Westminster as part of the Royal Society science and parliament pairing scheme. We got to visit both Chambers as well as learning about the history of the UK parliament and the interactions between the Monarch, House of Lords and House of Commons. Did you know that to reserve a seat in the House of Commons the MP has to personally place a hand-written green card in a slot above their seat?!
After coffee and biscuits in Portcullis House we were introduced to the scheme and heard from previous participants about their experiences and the forging of relationships between scientists and MPs/civil servants. Discussion ensued about the the lack of scientists in Parliament (apparently not as bas as we thought!), as well as the intricacies of the House of Lords such as there being no cap currently on the number of peers invited to join!
An hour later having been filled up on what was a very nice lunch we learnt about the different scientific committees in Parliament (note not Government, these are very separate things!) including being introduced to the Parliamentary Office of Science and Technology by the Director Dr Chris Tyler, The House of Lords Science and Technology committee by Lord Robert Winston, the House of Commons Science and Technology Committee (Victoria Charlton), Parliamentary & Scientific Committee by Professor Alan Malcom, and the House of Commons Library. I never knew there were so many committees but they are integral to the policy making process by scrutinising parliament and using evidenced based research as much as possible – something we scientists are very keen on!
Tuesday 3 December 2013
So the week continues in Westminster today with our location for talks being in Westminster Hall. After passing through security we settled in for a day of talks concerned with science and Government. The day began with an informative presentation by Jill Rutter (from the Institute of Government) on science at Whitehall. The largest proportion of permanent secretaries in charge of departments come from Economics backgrounds (26%) with only 11% from maths and far few from science effectively reflecting a ‘Science Free Zone’. She offered insights such as the fact scientists need to explain scientific evidence but understand that it is politicians who make the decisions and therefore need to be clear about the role.
Following Jill we had an entertaining talk by David McKay, the Chief Scientific Advisor at the Department for Environment and Climate Change who succinctly outlined the various conflicts that can exist between objectives of the Department e.g. an increase in renewable energy is is needed but this could conflict with the need to maintain energy security. He was also keen to provide us with back of the envelope calculations to make us think about the problems policy makers can face: e.g an average road of cars fuelled by biofuel would require an ~8km verge on which to grow this source of energy! (making assumptions about speed, engine efficiency etc).
We finished a packed morning with a talk by Oliver Grant from the Horizon Scanning Centre who examine longer-term strategy beyond the length of fixed term Parliaments and how policy might adapt/change.
The afternoon began with Chris Fleming from the Government Office of Science providing the top ten tips for academics which included building relationships with policy makers in Government, try to keep in mind the differences between lobbying and giving advice and hold realistic expectations!
This was followed by an interactive session on Science supporting UK Emergency Response (SAGE) and its interaction with COBR. We formed several small groups and were asked to imagine that we were giving advice as members of SAGE to COBR on two scenarios involving sub-zero temperatures and snow in the UK and the escape of a Flu virus from Myanmar!
The afternoon was finished by a talk from Alexandra Saxon at the RCUK which resulted in a very heated debate about funding science and impact, and a proposal by Dr Natalia Lawrence on producing a UK Evidence Information Service (effectively a database of science specialist who could be called on to give evidence).
After so many interesting talks we were already for a well-deserved drink at Walkers of Whitehall!
Tomorrow the shadowing begins!

Do we care too much about nature?
Over 80% of British adults believe that the natural environment should be protected at all costs. Yet, a recent report suggests that “government progress on commitments to the natural environment has been largely static” (1). Indeed, the budget for DEFRA, the Department for Environment, Food and Rural Affairs, has been slashed by 10% (£37m) and a reduction in green levies is likely as the government attempts to reduce domestic energy bills.

Can we share our planet with wildlife?
![]() |
Monty Don, Shared Planet, BBC Radio 4 |
Our environment provides us with amazing resources. As well as the obvious things like food, wood and water, it provides services like pollination, climate regulation and waste decomposition. However we are putting our delicate ecosystem out of balance by destroying habitats, over-exploiting animals and plants, polluting the air and rivers and causing climate change at a rate that hasn’t been seen since the extinction of the dinosaurs.
Last week the Cabot Institute hosted a debate for BBC Radio 4’s Shared Planet programme, asking whether we can better manage resources to live within our planet’s means, or whether there are simply too many of us to co-exist with wildlife.
![]() |
Fred Pearce |
Fred Pearce, science and environment writer, was one of the panellists. He argued that nature is dynamic and with better management of the resources we already have, we can reduce our consumption and live within the planet’s ability to recover.
![]() |
Kieran Suckling |
Kieran Suckling, Executive Director of the Center for Biological Diversity in Arizona, had a more pessimistic view. He believes that the human population is going to rise to a level far greater than the planet can sustain, and if we do not control our population level we will not be able to prevent ecological destruction on a global scale.
Global Extinctions
We are losing biodiversiy at an unprecedented rate. The 2012 Living Planet Report by the WWF estimated that we lost 28% of global biodiversity between 1970 and 2008. Fred took a more holistic view, that while of course we have a huge effect on the natural environment and should try and minimise damage, nature is resilient and will fight back. Foxes invading urban environments, weeds in a garden and rainforests’ ability to regrow in 15 years show that nature isn’t as fragile as we think. Animals and plants that depend on very specific environments are likely to be more at risk than more generalist species however and Kieran argued that we have an “ethical responsibility” to keep all remaining species alive.
How can we feed everyone sustainably?
![]() |

Every day around 870 million people do not get enough food. How can we hope to feed a predicted 9.6 billion people by 2050 whilst growing food more sustainably? Suckling described how industrial agricultural practices are highly damaging to the environment, for example pesticides which probably have a severe impact on bees. He argued that organic farms are unlikely to provide enough food for the growing population.
Globally, 19% of forests are protected, but rising demand for fuel and agricultural land means we are losing 80,000 acres of rainforest each day and probably 50,000 species of animals and plants every year. The good news, Pearce said, is that that we already produce enough food to feed the predicted 9 billion people, although we waste enough for 3 billion. Recent reports showed that 15 million tonnes of food is thrown away in the UK each year. He argued that we should be encouraged by the notion that “we can reduce our footprint just by being more economical”. The real challenge is how to make people understand that food waste is both socially and environmentally unethical.
Education
Fred mentioned that overall women are having half the number of children that their mothers had. This is in part thanks to medical advances, meaning that most children will survive to adulthood so fewer births are needed to build a family. It is also an education success story. Both the panellists agreed that “when education and freedom levels rise, the population starts to grow more slowly”. Opportunities for women to educate themselves will be critical in changing gender stereotypes and reducing the numbers of unwanted pregnancies. This is good news for human rights as well as managing our growing population’s impact on the environment.
Economics
The environment provides $33 trillion of benefit to us every year by pollinating crops, purifying water, cycling nutrients and keeping our climate stable. It would cost an estimated $76 billion annually to protect the environment, which is only about 20% of the money spent on soft drinks each year. Fred believes that putting a true price on economic resources and the cost of carbon emissions means that simple economics could solve the problem of environmental degradation by showing businesses that conservation is the less costly option. Kieran disagreed, arguing that both environmental and social problems stem from a capitalist consumer society. As the WWF Living Planet Report stated, “in too many cases, the over-exploitation of resources and damage or destruction of ecosystems are highly profitable for a few stakeholders in the short term”. Businesses and politicians work on too short a time scale to care about the long-term effects of environmental degradation.
So are there too many people for wildlife to thrive?
The debate ventured into the ethical question of whether animals and the environment should have the same right to live as humans. Does sustainable living have to be an “us versus them” question? Fred took a humanist view, but argued that we as a species need the services that nature provides. Kieran argued that we must not simply steal the most resources we can get away with, but live sustainably with other species.
Before the debate I believed that there are too many people on the planet for wildlife to flourish and at the end I would probably say I still felt the same way, however Fred managed to instil a bigger sense of hope in me. If governments really do get their acts together and we as a global population get our wasteful consumerism under control, we can turn the tides and make this a better world for both people and the wildlife we share it with.
If you would like to listen to the Shared Planet programme, it will be aired on BBC Radio 4 on Tuesday 24 December 2013 at 11 am.
