4 NEWS The Edinburgh Reporter Work in Edinburgh may help fix the polar ice caps Cambridge University announced that they are creating The Centre for Climate Repair, a centre for research which will find ways to repair climate change, global warming, call it what you will. The aim is to ensure that any future damage to Earth is arrested. One of the ideas which it has chosen to examine is being worked on here in Edinburgh. The deceptively simple idea is to make the clouds whiter and so more reflective, sending all the sun's rays back to space. This will have the effect of cooling the earth beneath, and may lead to complete reversal of the melting polar ice caps and other aspects of global warming. The initial idea is attributed to John Latham, but the way that it will actually work in practice is the result of almost 20 years' work by Professor Stephen Salter. Professor Salter is Emeritus Professor of Engineering Design at University of Edinburgh. He has invented many things (some of which you can see in the National Museum of Scotland such as the Salter Duck used as a model in the wave energy industry). This is not the work of a moment, but rather the work of many years with complex computer modelling and mathematical calculations. Professor Salter explained to us what he has worked on over the last two decades: "Cambridge University are setting up a group to repair the climate and they have been saying quite nice things about the work I have been doing. "I am hoping that this might at last get us a bit of money. "They said that they thought this is one of the better ways of repairing the climate and I hope that when they look into it a bit more closely they will agree. "I want to reflect more solar energy back out to space and I want to do this using John Latham's idea. The solar energy would not reach ground level. Instead it would be reflected back Raeburn Place development now visible The development at Raeburn Place is making progress with the installation of the first steel carried out early last month. Raeburn Place Foundation report that the groundworks are complete and now anyone passing by can see the progress above ground. This development includes sport facilities principally for rugby and cricket but also including a sprint track and a purpose out to space where it does not do us any harm. "We need to reflect about 0.5% of what is coming in. It's a tiny amount and you would not be able to see this by looking at the cloud from above. This will change the reflectivity of clouds by changing the size distribution of the drops in the clouds by increasing the number of 'condensation nuclei' that you need to form a drop." Professor Salter confirmed that this can be done anywhere in the world where there is fairly clean air and some sunshine and some wind. The energy comes from the wind and it is used to move the ships through the water to make energy to filter the water and pump it out. It is distributed by turbulence - by the wind blowing over the sea. He explained that the spray vessels could be used fairly near the Arctic because there is more energy (or sunlight) going in there during the couple of months around mid summer than there is in the Equator. He said:"We need to choose where and when to do this and by making the correct choice we might be able to get the best combination of cooling and changes to rainfall.” What is the idea? John Latham's idea is to brighten the clouds above the earth by spraying sea water at them. (The sea water would be 'cleaned up' before being distributed into the air, but it is the sodium chloride which is key.) Using the correct size of water droplets would mean that more of them attach to aerosol particles - and they would be smaller and whiter. We all know that dark clouds mean a storm is coming - and usually with large raindrops. This is the opposite - whiter clouds with smaller droplets. How will it work? Unmanned hydrofoil ships or spray vessels will be deployed around the world anywhere there is fairly clean air and some wind - the energy comes from the wind. They will be powered by renewable built gym. There will be a stand to accommodate around 2,500 people and it will be home to the Museum of International Rugby. Along Raeburn Place there will be commercial units for restaurants and shops set back in line with the Raeburn House Hotel. Milk & Honey will be one of the new businesses to take up residence there in autumn this year with what they call an upmarket gelateria. City hairdressers Charlie Miller energy and by Flettner rotors instead of sails. The nozzles will spray water at the grey clouds, turning them white. The resultant cold air will fall to the sea surface. Estimates used in Professor Salter's research show that 300 such vessels could save Arctic ice, coral and moderate hurricanes all over the world. What will the outcome be? The clouds become more reflective. It is acknowledged that although it may be highly effective this is an emergency treatment of the problem and could be reduced if carbon emissions are reduced across the world, otherwise it would continue to be used as a 'sticking plaster'. Professor Salter told The Edinburgh Reporter : "The end result would be that we would be going back to the climate that we had in pre-industrial times. We could moderate hurricanes making them less aggressive, save the coral in the Barrier Reef, stop sea levels rising and stop losing the Arctic ice. That is probably the most important thing to do in the short term because if we lose the ice we warm up the seabed and we warm up the permafrost around the Arctic. That releases methane which is a very much nastier greenhouse gas than carbon dioxide. We could get a very unpleasant positive feedback where warmer seas make more methane and more methane makes warmer seas. That could be very dangerous indeed." At the beginning of the month climate scientists Dr Emily Shuckburgh was appointed as the first director of the Cambridge Carbon Neutral Futures Initiative, and The Centre for Climate Repair is part of that. At the time of her appointment Dr Shuckburgh said : "Climate change is one of the most pressing problems facing humanity. The University of Cambridge has an opportunity to use its position as one of the world’s foremost academic institutions to take a leading role in also signed up for one of the units last June. Josh Miller, Joint Managing Director, Charlie Miller, said at the time: “Charlie Miller’s essence has always been evolution and we are excited to announce this next step in our journey. Stockbridge is a key location in Edinburgh and one we have had an eye on for a while. The new development at Raeburn Place will provide us with a salon that meets our stringent requirements, in a popular part of the city. We look forward to finding ambitious solutions to this complex issue. “Cambridge already has many groups working on climate-related research. This Initiative aims to bring together these groups to tackle this urgent global challenge holistically. This is about addressing every aspect of a sustainable future - the impact it will have on our lives, our work, our society and our economy - and ensuring decisions are based on the best available knowledge.” So it comes down (at least partly) to the work of one scientist in Edinburgh who may be able to contribute to that knowledge. He says that to make this idea commercial and build the flotillas needed it would need an investment of around £100 million a year to finance the total cost of around £1billion. There are some other 'showstoppers' according to Professor Salter. He concluded : "We need to remove a few of the possible showstoppers. One of them is whether we can filter the water well enough so that it does not clog the nozzles. "We want to understand all the side effects whether we would make climate change that we don't want. There is some very exciting and encouraging work coming from Norway which shows that we make dry places a bit wetter and wet places a bit drier. The effect is biggest in the Arctic but we need to be quite sure about that and quite sure about the size of drops being opening our doors in 2019.” Other tenants include Marks & sprayed - and that they are all the same size. That is very important." Even the design of the ships which may be used as spray vessels has something to do with Edinburgh. Professor Salter explained to us that they will not have textile sails like a normal sailboat but something called Flettner rotors to power them. The cylinders spinning about their axes with air blowing across them will act exactly like an aeroplane wing. Anton Flettner first came up with that design in the early 20th century and sailed a ship which he had converted from the Baltic to Leith. He won the race against a normal ship with sails and took it to New York. Sadly his order book was left unfulfilled as a result of the 1929 Depression.

@EdinReporter /EdinReporter edinburghreporter theedinburghreporter.co.uk NEWS 5 Remembering the moon landing The UK Government has announced that it is looking for people across all four nations to share their memories of the Apollo 11 moon landing in 1969. A selection of the submissions to the crowd-sourced campaign, led by the UK Space Agency and Arts and Humanities Research Council (AHRC) , will be shared with the public on 20 July 2019, marking 50 years since Neil Armstrong and Buzz Aldrin landed on the Moon. The campaign is intended not only to discover first-hand memories but also to explore how the moon landings touched almost every aspect of popular culture, from cinema and art, to literature and music. For anyone who may not have watched the footage live, there is an opportunity to get involved by sharing their stories about how space exploration has inspired them or led to a career in the sector. Entries could include a grainy photograph of a family huddled around an early television to watch this iconic moment; a scrapbook of newspaper cuttings from July 1969; or a personal account of how the Moon landing has shaped a work of art or led to a lifelong passion for science fiction. Science Minister Chris Skidmore said: "Ahead of the 50th Anniversary of the Moon landing, I hope people across the UK share their Moon memories, ranging from photos to diary entries, to help give us a unique and fascinating insight into one of the most celebrated moments in our history. "Landing on the Moon was unthinkable at the beginning of the twentieth century, so when Neil Armstrong heralded the moment as, ‘one giant leap for mankind’ those words rightly have echoed through the ages. "Through our modern Industrial Strategy, we are backing the UK’s thriving space sector so that the young people inspired by this great event of the past will have opportunities to work in the industry’s highly skilled, well-paid jobs of the future. Tim Peake, astronaut at the European Space Agency (ESA) said: "The 1969 Apollo 11 Moon landing was not just a pivotal moment in space exploration, but a defining moment for humanity. Whether you were too young to witness the first footsteps on the Moon, or old enough to see it for yourself, the Moon landing has inspired so many people over the past fifty years. "I hope that this campaign from the Arts & Humanities Research Council and UK Space Agency will not only help people to reflect on the historic and cultural significance of this anniversary, but also inspire the next generation of scientists, engineers and astronauts." You can submit your memories and personal stories via moonlandingmemories. com and you are encouraged to share them with social media using the hashtag #MoonMemories. Memories and stories can be uploaded over the next month, with the submission deadline falling on Tuesday 18 June 2019. Cashback for Communities works More than £18 million seized from criminals funds projects helping to divert disadvantaged young people away from crime. The Cashback for Communities scheme reinvests criminal assets into community projects which support young people into positive destinations, diverting some away from potentially criminal or antisocial behaviour. The next phase of funding means that total investment in the programme, unique to Scotland, reaches almost £110 million since it began in 2008. CashBack has funded a variety of projects in the past 11 years including the Celtic FC Foundation, the National Autistic Society and Impact Arts which all provide opportunities to raise the attainment, ambition and aspirations of young people from areas of deprivation. Minister for Community Safety Ash Denham said: “We want every young person growing up in Scotland to have an equal chance of success no matter their circumstances – CashBack has a vital part to play in expanding young people’s horizons and helping them reach their full potential. “Since Cashback for Communities began in 2008 we have delivered nearly two and a half million activities and opportunities for young people across all local authorities in Scotland. “The next stage of CashBack will have particular focus on projects that support young people and communities most affected by crime. I’m pleased to say that we have increased funding for this latest phase by £1 million – taking the total amount available over three years to £18 million. “The numbers of children referred to the Children’s Reporter on offence grounds or prosecuted in the courts have fallen substantially over the last decade and our Cashback programme supports that progress by giving many of Scotland’s most disadvantaged young people a wide range of positive opportunities to challenge themselves and inspire those around them.” Phase 5 of the CashBack for Communities programme is now open for applications running until 28 June 2019.
