Emily Collins, medical student at Keele University If you’ve seen the news recently, you’ll probably have heard many loud opinions battling to have their say on fracking. Fracking is a process that is unfamiliar to most of us, but which could have big effects on our world, depending on who you listen to. So what is it? And why is it such an important issue? Fracking (hydraulic fracturing) is a feat of engineering aimed to increase the yield of natural gas gleaned from the earth, in order to be used as fuel. As a fossil fuel, formed when marine plankton and ancient plants trapped sunlight energy and carbon over millions of years, natural gas is an unsustainable energy source and burning it produces carbon dioxide. Drills dig deep into the earth, vertically then horizontally, while pumping in water and chemicals at high pressures to open up fissures in the shale rocks way down deep: this frees trapped gases. These are then captured and piped off at the earth’s surface, ready to use as fuel (helpful video: http://www.bbc.co.uk/news/world-us-canada-23320540.) Having been widely used across the US, the government has recently announced the lifting of a temporary ban of fracking throughout the UK which has sparked controversy and protests, such as those in Balcombe and elsewhere. Why the enthusiasm? Hard to reach oil and gas can be accessed by fracking. It has been estimated that there is as much as 1,300 trillion cubic feet of shale gas underneath the UK – a tenth of which, if extracted, would be the equivalent of 51 years’ gas supply. (1) There are two main possible benefits: first, UK gas prices could be driven down, as they have been in the US. This could be a big boost in the days of our troubled economy, where many families struggle with meeting the rising cost of energy bills – but as this letter to the FT from a senior (republished here) explains, even using very optimistic assumptions only investors in the extraction companies and the Exchequer are likely to benefit, unless gas imports are penalised. At the same time, the cost of solar panels has dropped 80% due to a surge in Chinese production. Is it really just a coincidence that Osborne’s father-in-law is an oil and gas lobbyist? From an environmental perspective, electricity can be generated from natural gas at half the CO2 emissions of coal (potentially at least) so, compared to coal it could plausibly be a step in the right direction. But there are big question marks on wheter this is true – see below – and is coal really the benchmark we should be using in 2013? Another potential benefit of fracking – especially in the context of today’s record unemployment - is the creation of jobs in Britain. David Cameron claims that as many as 74,000 jobs could be supported by the growth of this industry (1). If true, this would be hard to overlook, although many of them would be temporary. But the job creation argument applies just as strongly to investment in the green economy, as the Green Is Working campaign and this report from the Green Alliance show. Even if realised, the benefits of fracking come with big risks, and could cause lasting damage to our planet and our health. Water usage and chemical contamination Fracking uses huge amounts of water – just one site requires millions of gallons of water. This will compete with water resources in areas which are already prone to and experiencing shortages, areas which are also expected to increase with climate change. Transport of these large volumes of water to and from fracking sites will also have environmental impacts. In addition, there is serious public health concern about the risk of water quality being affected, with a concern that carcinogenic chemicals such as benzene, toluene, xylene etc among many others, used in the water will leak and contaminate groundwater around the site. Earthquakes There are concerns that fracking can cause earth tremors. In 2011, two small earthquakes occurred in Blackpool following exploratory fracking. Several reports have been conducted into the matter and it remains possible that future fracking will lead to some tremors. However, a recent report from the Department for Energy and Climate Change claimed that the risks of structural damage from these tremors remain low, and the process has been given the green light, albeit with stringent regulations. Climate change The science is telling us that we really need to keep most remaining fossil fuels in the Earth if we want to avoid catastrophic climate change, as highlighted by Bill McKibben's Do The Math talk (coming to the UK this Autumn in a 'Fossil Free' tour coordinated by People and Planet!) In that context, is fracking just a distraction from developing renewable sources of energy? Cameron, like Osborne, says ‘we’re not turning our back on low carbon energy’ - just using fracking to help meet our energy needs – but we could do that with sustainable energy too. Does the move just encourage continued dependence on fossil fuels, ‘one last fix’ before we change? As Friends of the Earth’s Head of Campaigns, Andrew Pendleton, said in reaction to the 2013 Budget: "This is yet another fossil-fuelled Budget.... Our economy desperately needs new ideas, but George Osborne is a 19th century Chancellor, using 20th century tools to fix 21st century problems". Natural gas is mostly methane – which is over 20 times more potent as a greenhouse gas than CO2 – and it has been found to leak from fracking sites in quantities much larger than originally thought. Burning fracked natural gas is only a greener alternative to coal burning so long as gas leakages into the environment are kept to a minimum, specifically below 2%. Studies predict, however, that leakages may be significantly higher, with a recent study in Utah finding a leakage rate of 9%. A New Scientist article published yesterday cites that if rates are around 10%, at the top end of estimates for the US, then the escaped gas would increase global warming until the mid 22nd century. The climate is a very complex thing: the same article also notes that side-products of burning coal, sulphur dioxide and black carbon, actually cool the climate to some degree and offset some of the warming created by the production of greenhouse gases – although they also have negative health effects. There’s a lot to consider when it comes to the debate about fracking. What damage to our planet is too much? Will fracking really be the solve-all economic miracle the government is claiming? The debate is open – what do you think?

18/6/2013 Methane 'plumes' in the Arctic, positive feedbacks - and why we all need to act on climate changeRead NowJake Campton, UWE ""Dense plumes of methane over a thousand meters wide" have been discovered leaking from the permafrost around northern Russia following continued warming in the region - and the rate of release has been accelerating. Why does this matter? Methane is a potent greenhouse gas with 20 times the warming potential (heat-retaining ability in the atmosphere) of carbon dioxide. That makes it extremely problematic. The total amount of methane beneath the Arctic is calculated to be greater than the overall quantity of carbon locked up in global coal reserves, meaning a planetary time bomb is currently ticking in northern latitudes. It is not only the scale of these outflows that is unprecedented; it is also the alarming frequency at which they are occurring. Dr. Semiletov’s research team that made the discovery found hundreds of these plumes, similar in scale, over “a relatively small area”. Our planet’s weather has been thrown into disarray in recent years; the last decade has witnessed more weather records broken than the entire last century! The more we continue to heat the Earth, the quicker the permafrost will melt, increasing the rate methane can escape its icy prison; a positive feedback effect (Arctic ice is not the only one either, there are a lot in action - see this page for info on a few others). We will eventually become locked in by this effect, with heating leading to more rapid heating, accelerating the whole process further still. Add in the reduced albedo effect from the rapidly receding glaciers of Greenland and surrounding area and the danger we are in becomes clear. We are in trouble. It doesn't take too much time reading up on climate science - as described in a World Bank report just out - to work that out. What's more, it's not just an issue for the polar bears; it's a health issue too. Humans are reliant on the environment and most critically, a stable climate to provide food; it doesn't magically appear on our supermarket shelves (even if that's what many kids now seem to think!) The last few years have seen intense droughts ravage vast swathes of the planet, including the major grain producing nations: Russia, Australia and the U.S. among others. By mid-2012, the U.S only held enough grain for just 21 days. The increased scarcity of its staple crops caused sharp price spikes too - corn reached $8.39 a bushel by August 2012, an all-time record. Farmers were forced to cull large numbers of livestock as they suddenly became too expensive to feed. Are these the sorts of trends we should expect to continue looking forward? Grains becoming so expensive that meat is affordable only for the richest? And what about the poorest nations? What will the implications for malnutrition and food security be if the main exporting nations are unable to meet export demands? In 8 out of 13 recent annual harvests, global consumption has exceeded production, eating away at our grain buffers. A few more volatile growing seasons, and we could all be in real trouble. No nation is safe from a perturbed Gaia… I blame a lot of people for this current mess. Not enough people care. That fatalistic idea, 'I'm one person, nothing I does matters' is, frankly, crap. 65 million UK inhabitants doing their bit, and I don't mean just recycling here, would make a substantial difference. If we were also to factor in 700 million Europeans and 300 million+ Americans - not to mention a billion plus Chinese and others - you can see the potential for drastic, meaningful, global change. You see, you are not just one person; you are every environmentalist that plays their part in this conundrum. You are hundreds of millions of people. That is where our power to change lies; in sheer numbers. Industry is changing, albeit reluctantly, now society must change, too. My biggest fear is that most people won't act. It's a failure of our education system, a neglect of our moral responsibility - and it could be a catastrophe for humanity. I realise we have had many decades of industrial pollution before us, but they weren't aware of the implications of their actions - and they were also far fewer in number, each consuming much less. If current trends continue, things could become truly and irreversibly messed up within a couple of decades and that terrifies me. It will be this generation and our immediate predecessors, the ones that peered into the precipice, who will be blamed. We could still make a meaningful impact on the current situation but I worry that we won't. We could have a great future ahead of us, but many forget that humanity and the environment are inherently intertwined. Until we recognise Earth as the delicate, dynamic and precious entity that she is, and treat her with the respect she requires, we will continue unabated along this perilous path. The bridge is out up ahead, we need to change paths. I sometimes worry that the window for action has already closed, it’s something I feel bitter about, something that angers me greatly. There are people out there who are particularly responsible, who keep ignoring the problem, and their negligence is literally costing the Earth. I believe that if more people shared my sense of impending danger more would get done. I’m not sorry if this offends you, it's probably because you are the sort of person I am referring to. If my words are intrusive in to your way of life, maybe your way of life is part of the problem. When something so big is at stake, I think you have to ruffle a few feathers - feel free to comment if you wish to discuss anything further, I’ll gladly respond. I know its complex, and it can feel like whatever you do is a drop in the ocean -sometimes it's difficult not to feel frustrated and concerned - but there is lots you can do. Start off by educating yourself; there's a lot of information out there - but always be critical. Outspoken anti-climate behemoths like the Koch brothers, use political and monetary leverage to fund anti-climate change ‘research’ and spokespeople to help maintain the status quo for their incredibly irresponsible and selfish gains. Be wary… Are you a carbon addict? Take the test... Below are some ways I try to reduce my impact on the environment. They're small steps that don't require much effort - why not give some of them a go? Eating less meat - I can't understand why people assume it's a right and a necessity to eat meat every day, but this is one of the most effective ways you can reduce your burden, as well as making yourself healthier in the long run. We have molars for a reason; we are omnivores, not carnivores. Cycling and walking wherever you can is another great step - driving a few miles down the road is a missed opportunity to stay fit, a pointless waste of petrol and needless emission of carbon. I realise some people can't - fair enough, but most could. I bike everywhere, I feel great because of it and I’m very fit as a by-product. You could shower instead of filling a bath, turn off plug sockets at the wall to avoid appliances ‘ghosting’ electricity, wash your hands with cold water instead of hot to save energy, boil the exact water you need when making tea, by cloth bags for shopping trips and avoid plastic, use LED light bulbs; expensive but they can last over 30 years and use just 10% of the electricity of halogen/filament bulbs! Wear an extra jumper instead of cranking up the heating in colder times, turn down the brightness on your laptop to reduce energy consumption and there are many more. These may sound like small things, but, when added up and multiplied by the efforts of millions of others, cumulatively, we can drastically reduce our strain on Earth and preserve the environment for future generations, as is our responsibility. Things you do in your daily life matter, and - imperceptibly - help start to shift the norm. However, we need political change too, and contacting your MP and MEP, signing petitions or even getting involved or setting up local campaigns isn't actually as hard as it can seem - Google is your friend here. Anyway, rant over - you're all free to act as you see fit of course, but what I'd really like to say, and excuse my French, is that you personally don't screw it up for future generations because you can't be bothered to act responsibly. Acting together, we have a chance to change our future for the better. There’s no I in team, but there is in humanity. Share yours. Izzy Braithwaite A few weeks ago, I went to an Enough Food IF training day, organised by a number of the big organisations behind the campaign. It aimed to give us the background needed to visit our MPs to talk about two of the main asks – aid and tax – in advance of the Budget and the Finance Bill. The question the IF campaign asks is ‘IF we produce enough food to feed everyone, why do one in 8 people go hungry?’ The crux of the argument is that IF we can change a number of key things about our current system, we can make sure everyone gets enough to eat. I couldn't really argue with that, and I decided I wanted to meet my MP about it - which I did as part of a group on Friday afternoon, and really enjoyed. How is the campaign linked to climate and health? I’ve been interested in global health for several years, focusing more recently on how climate change affects, and will affect, global health, which is how I got involved in Healthy Planet. It seems to me that one of the big impacts climate change is having on people in the poorest countries – and one of the biggest effects it’s likely to have on health in the future - is through food. It makes a lot of sense to me that IF we can build a fairer food system, including through changes in the way tax works for developing countries, that will help reduce the impact of climate-induced crop losses on the health of the poorest. Although the Enough Food IF campaign doesn’t focus explicitly on climate change, there’s a fair amount of evidence that land grabs, food price speculation and short-sighted biofuels policies – all of which the campaign aims to highlight and tackle – act alongside more unstable weather and inadequate social security to push more people into food insecurity. But even if it weren’t for climate change, we have massive injustices around food and access to it; climate change just exacerbates them. You can't really disagree that a world in which almost a billion who don’t have enough to eat while so many others throw away as much as they do, and while so many people are suffering the health effects of obesity, is kind of crazy. Tax and development I didn’t know a lot about the ins and outs of tax policy and how it related to international development before getting involved in the IF campaign, but came away from the training day and my reading online afterwards with a better understanding. I learnt how crucial tax revenue is in enabling developing countries to finance public services, and had no idea that tax avoidance currently costs them to the tune of 3 times as much revenue as they receive in aid each year. I was shocked to learn how Associated British Foods, which produces vast quantities of sugar in Zambia – a country where many people struggle to afford enough to eat – has managed to ensure that it pays less tax in Zambia than the woman in this ActionAid video, a shopkeeper who sells their sugar. Then there was the story about the Rwandan revenue authority, set up with a grant of £24 million from DfID, which now generates that much in tax every 3 weeks. Talk about value for money. That revenue stability enables the Rwandan government to finance essential public services like schools and healthcare, and helps it to ensure that it’s people have enough to eat. If we want aid to be effective and countries to be able to finance aspirations like Universal Health Coverage, tax should be a global health priority, and it was great to have some real examples to illustrate that at the meeting. The meeting Alison Marshall, who works at Unicef UK and had signed up as a coordinator for my borough on the online lobbying forum, managed to set up a meeting with my MP Jeremy Corbyn for yesterday afternoon, and put everyone who’d expressed an interest in touch with the other interested people in Islington North. About half of those on the email list were able to make it, with quite a range of ages, jobs and backgrounds. Most of us had never met one another before the meeting, so we divided up tasks and subjects in advance and turned up for a chat half an hour before. Unforeseen circumstances meant the office was unavailable that day so we had to relocate, but fortunately an incredible woman called Theresa had offered up the nearby Finsbury Park Community Centre for the meeting. She filled us in on what things are like in the ward, which is one of the most deprived in England, and it was sobering to hear some of the statistics and stories. I'd read a bit about Mr Corbyn’s voting record and past involvement in international development-related work, so I had thought he would probably be happy to support the 0.7% aid goal, but I hadn’t known how he’d respond to the ask on tax transparency, which is a relatively technical one and took more explaining. It relates to the upcoming Finance Bill, and specifically asks that it extends DOTAS (disclosure of tax avoidance schemes) rules to any which impact on developing countries, in order to help them tackle tax avoidance by multinational corporations operating in their countries. The DOTAS regulations help tackle corporate tax avoidance in the UK, and it essentially requires companies to disclose any schemes they use to get out of paying tax. The IF ask (briefing here) is to introduce a similar requirement for UK companies and wealthy individuals to report their use of tax schemes with an impact on developing countries. It also asks that the bill require that when such schemes are identified the UK will use its existing powers under bilateral and multilateral treaties to notify developing countries’ tax authorities, and to assist in the recovery of that tax. Of course, transparency doesn’t in itself prevent tax avoidance, but it does make it much easier to hold companies accountable, and helps to enable developing countries to enforce and improve their laws. And of course UK action is not the whole of the answer – that will include international cooperation, which hopefully the G8 will make progress on, and country-by country reporting amongst other things. But it would be a good step on the road towards a fairer and more effective tax system, and could potentially set a useful precedent for other countries, and the EU, to follow. I quite like a challenge, so I’d kind of hoped we’d have to argue our case a bit more, but in fact he was very much in agreement with both of our asks, and agreed to write to the Chancellor and to lobby other Labour MPs and to raise it after the Budget and the Finance Bill. I suppose I can hardly complain that I have an MP who cares about international development and takes an interest in the details of how we should contribute to it even though most of his time is spent dealing with much more local issues. He told us about some of the problems he'd been trying to fix recently, such as the story of a guy who’d been sleeping on a bus for months who he’d just spent the afternoon trying to get re-housed. I hadn’t really thought there would be many parallels between politics and medicine before the meeting - not least because doctors tend to be trusted by the public whereas many politicians aren’t - but if I'd had to guess his job without knowing, I could easily have guessed a doctor or an overworked social worker. Both are both more of a lifestyle choice than a nine-to-five job, and both doctors and politicians have the opportunity to change peoples’ lives for the better. Now is when the real test for the campaign begins - making sure there's enough pressure, and enough other MPs on board - to push through specific reforms. Which is where you come in... How can you get involved?
