Light of the world

Experts from around the globe gathered at Leicester’s De Monfort University in the UK this week to discuss ‘artificial light’ and how it is not only affecting the world we live in but is also increasingly helping define it.

The fact that light at night affects us adversely more than we might think is not something many of us give a second thought to - let alone consider it necessary to be discussed at an international conference.

But those at ALAN 14 - the second ‘Artificial Light at Night’ annual conference - had a significantly different take and highlighted a number of concerns that need to be taken seriously.

The scientists and researchers had travelled from the different parts of the UK, Ireland, the United States, Europe and Australia to present their findings on light-related topics and related research across the fields of health, biology, pollution, ecology, technology and design.

ALAN 2014 examined the use of artificial lighting at night in all its forms, as well as the spectrum of adverse effects that artificial light at - known collectively as light pollution - night may cause.

The theme coming through loud and clear is that society at large is barely beginning to recognising that such liberal and indiscriminate use of illumination is at a mounting cost to both the environment and ourselves.

Interestingly, an increasing number of scientific studies are now seriously questioning the long-held premise that humans are largely immune to the effects of artificial light at night.

Research is now confirming that artificial light - even in quite small doses - disrupts sleep, confuses circadian rhythms and impedes the production of the hormone melatonin.

All of which is bad news if the consequences of excessive exposure to light at night really do include an increased risk for obesity, diabetes, cancer and cardiovascular disease.

Back in 2012 the American Medical Association (AMA) called for more research into the risks and benefits of occupational and environmental exposure to artificial light at night and for the introduction of new lighting technologies at home and at work that minimise circadian disruption.

Technological advances such as LEDs (light-emitting diodes) have improved the potential for better targeted lighting - but for now they are often brighter and more intrusive than the old lights they are replacing.

Much of our modern light - whether from TVs, computer screens, smart phones and electronic gadgets or from outdoor lighting of one form or another - is also ‘blue’ rich and so proves even more disruptive to the 24 hour biological process that regulates the body's functions.

According to conference organiser Prof Martin Morgan-Taylor, of the School of Law, De Montfort University, Leicester, and a Legal Advisor to the UK Campaign for Dark Skies, the physiological effects caused by lighting may be similar to noise.

"Admittedly, there are comparatively few studies as yet on the problems caused by lighting, but lights can and do wake people up, just as does noise," he said.

"Moreover, with light it appears that the subject does not need to be fully awakened to suffer the same negative effects as someone who has been deprived of sleep altogether."

This means that people's health can even be adversely affected by ‘security’ floodlighting and, what the Chartered Institute of Environmental Health (CIEH) refers to as, ‘light briefly turning on and off' during the night.

Prof Morgan-Taylor stated the research concerning cancer risks does not restrict itself to lighting that wakes the subject because risk factors are akin to the levels of night-time light entering a bedroom.

Paul Marchant, of Leeds Metropolitan University, questioned the widely held perception of ‘improved’ (brighter) lighting is always beneficial in reducing road accidents and crime.

The generic objection to this - based on the premise that light equals protection and darkness represents danger - is that we need all this light for safety and security, he said.

Such common belief goes a long way to explain why many supermarkets, petrol station forecourts and car parks, as well as our own driveways and yards, are lit more than ten times as brightly as they were just 20 years ago.

"In fact, the issue of light at night and safety is rather more complex, and there is little compelling evidence to support widespread such mis-assumptions," he said.

"Ever-brighter lights can, for example, actually diminish security by casting glare that impedes vision and creates shadows where criminals can hide."

Emma Marrington, CPRE Dark Skies campaigner and author of ‘Shedding Light’, a survey of local authority lighting policies, said some local authorities are taking steps in the right direction.

She said the research had revealed no evidence to support the fear that adjusting or dimming street lights impacted on public safety.

"We urge councils to do more to control lighting in their areas and ensure that the right lighting is used only where and when it is needed."

"We're not advocating changes where they're not appropriate - but why shine bright lights on residential streets, quiet roads and open countryside throughout the night when they are not needed?"

The consistent theme emerging from ALAN 14 was that there are many different aspects to artificial light at night and the effects on our well-being, ecology and life in general are only just beginning to be understood.

We will, no doubt, continue to tinker with the natural world and all its variances, and the exponential growth of artificial light in our homes and across the planet shows now time of dimming yet.

In the meantime, conferences like ALAN will gradually produce evidence in an attempt to redress the balance.

And one day there may come a time of new enlightenment - when we release that at certain times of the day we need dark more than light.


The conference was hosted by Leicester De Montfort Law School, De Montfort University, and co-organised with the EU COST Action LoNNe (Loss of the Night Network) in association with the International Dark Sky Association. My thanks to Martin Morgan-Taylor and Katie Scott.

Building for the future

A positive and infectious energy surrounds Karl Hick. He's a potent mix of athlete, scientist, accountant and developer. And the list of nine companies on his business card seemingly leaves no stone unturned.

With an award-winning home builder to head up, not to mention a timber frame firm, a healthcare and retirement homes specialist, an energy company, a waste company, a renewables firm, and two product supply companies, this is a man with an insatiable appetite for business.

He's been at the helm of the hugely successful Larkfleet Group for a dozen years now, running a growing portfolio of interconnected companies that are steadily setting new national benchmarks in home construction and renewable energy.

Larkfleet - based in Bourne, South Lincolnshire - specialises in building energy-efficient housing and investing in research and development of innovative new building designs, materials and construction methods.

The company is also a major developer of sustainable energy projects, as well as being a provider of energy-efficiency improvements for new and existing buildings.

"From the outset I wanted it to be a different company - built around a sustainability ethos," he says.

"At the time this was a unique proposition in the industry and others were not interested in such a long term approach."

Larkfleet was initially focused entirely on house building and but recognising the opportunity for diversification, the scope was quickly expanded to embrace developing more energy-efficient and sustainable homes, and renewable technologies.

"I can't put the world right but I can do my little bit to help the green industry and make it a commercial success," he says.

Larkfleet - one of the few builders to offer solar panels on new homes as standard - has now built more than 2,500 homes, developed some of the country's biggest solar energy parks and is exploring renewable technologies in waste and power.

Typical of the latter is a new research project to generate ‘carbon-free' electricity via an experimental solar power system installed on land at the Bourne headquarters.

Its panels focus the sun's rays onto water-filled metal tubes and the energy generated can be harnessed to heat water or produce steam to drive a generator for electricity.

The panels are mounted on a rig which rotates to track the movement of the sun through the sky.

Karl hopes that such a system - which is attracting worldwide interest - can be integrated into traditional power stations.

"The solar steam could be fed to the power station generators so fossil fuel would only need to be burned at night or on days when solar power is not enough to meet demand," he says.

"This is very much a long-term project - we will trial the technology fully over the next couple of years before coming to any conclusions about its future potential."

The solar steam initiative is very much a product of his enquiring mind and science background.

In his younger days Karl was also an accomplished athlete and it is the competitive edge from his achievements on the track that he brings to the business world.

His pioneering spirit can also be seen behind the development of two prototype homes alongside the company offices - a Green Deal Eco House and a new PassiveHouse, a test home using new materials and construction methods.

The Green Deal Eco House demonstrates how buildings can incorporate both Green Deal and ECO-funded energy saving measures in housing and commercial buildings.

Larkfleet's PassiveHouse shows how lightweight pultruded glass-reinforced plastic (GRP) composite beams and panels could revolutionise the way in which future homes are built.

The house is designed to be ‘factory built' using mass-produced modular components that can easily installed on site with minimal labour and waste, all much quicker than a traditionally built house.

Its light weight also offers the potential for building such homes on foundations that would rise in response to flooding.

Another aspect of Larkfleet's sustainable energy business is developing large photovoltaic solar farms, adding solar panels to new and existing buildings, and refurbishing existing homes to reduce their carbon footprint, energy use and energy costs.

"The reason solar works so well in the UK is because you need a combination of sun and relatively cool temperatures for optimum energy output," explains Karl.

He describes it as a "very simple technology" but one that still needs government support in order to make it practical to deliver.

"We can do a lot more with solar energy generation in this country and it is something I think should be developed and supported more," he says.

"Wind should also be used more. People don't seem to want it but it is one of our biggest resources in the UK - the difference may come if the lights go out and then people will say ‘why didn't we invest in wind power'?"

Karl believes that if the subsidies given to the nation's nuclear power industry were matched for renewables the country would be in a very different situation.

"Thirty per cent of our energy could come from solar and it would be much cheaper, cleaner and simpler than nuclear," he says.

The scientist who became one of the country's most innovative developers has created a company of our time - a true leader when it comes to home building, sustainable development and renewable energy projects.

Failure is not an option

Photo: Clive Simpson

Many of the most successful people have experienced their fair share of failure before going on to do great things.And international businessman Mike Greene would count himself as one of them.

Born and raised on council estates, he worked hard to achieve a financially rewarding career after overcoming bankruptcy at the age of 27. Now, he’s a well-known business entrepreneur and angel investor, and a director of companies, trade associations, charities, marketing and retail organisations.

Mike greets me enthusiastically when I arrive at his family home in the heart of the South Lincolnshire Fens.As we chat whilst sitting at a large farmhouse table in the family’s garden conservatory on a fine summer’s afternoon it soon becomes evident that Peterborough’s very own Secret Millionaire is a man with a mission.

And, if there are any secrets when it comes to success in business and life, then here might be some answers.His appearance on Channel 4's Secret Millionaire programme in October 2011 was a life-transforming experience."It really consolidated my thinking about my past and its effect on what I have subsequently achieved," he says.

In the programme he became involved with various organisations working with underprivileged youngsters in Peterborough."It was a deeply moving experience and I was affected by how selfless some people can be in giving so much of their time and emotion to these causes."

But it was the kids themselves who proved the real eye-opener."Most of them had a really tough start in their lives and all of them had some real challenges to contend with. However, the ways in which they chose to deal with them were very different."

Afterwards Mike sold his main business and took a three month sabbatical during which he worked to raise £100,000 for a hundred charities in a hundred days.

The television programme and subsequent challenge inspired him to commit one-third of his time to helping charities and mentoring others to help change their lives for the better.

"We live in an instant world and too often we want a quick fix," he observes."The National Lottery and programmes like X-Factor lead a lot of people to believe that we can get rich quick without hard work - but life isn’t like that."

Mike’s own journey to fame and fortune stemmed from humble beginnings.His father abandoned the family when Mike was just a few years old, leading to eviction and living in an old people’s home before being re-housed in cramped, rented accommodation.

"It wasn’t until the family moved to Peterborough when I was 11 that I finally got a bed to myself and no longer had to share with my siblings," he says.

"Despite the tough early years I always swore that I would be a successful businessman. Even as a young boy I told my mother that one day I would be a millionaire. And I really believed it."

Today, Mike is living proof of his own mantra - ‘It's not where you start that matters, it's where you end up’.He’s a respected global retail consultant, an international speaker, a professional mentor, a philanthropist, an endurance adventurer, and a passionate charity fund raiser.

Above all he is a dedicated family man, with wife Julia and their two daughters, who were part of the motivation for writing his best selling and inspirational book Failure Breeds Success.

In a nutshell his book guides the reader through a series of steps to define what success means - in all its definitions - to them personally.

For Mike, life and business are inextricably connected. And whether its mentoring enthusiastic young entrepreneurs or speaking to groups of several hundred he doesn’t pull any punches."People spend more time planning their next holiday then they do the rest of the their life," he says.

Mike currently supports a number of charities in the Peterborough area, has around 20 investments in start up businesses and is on nine boards, five of which he chairs.

"I think I've got just about a perfect balance," he says. "It's about as close as I can get it to a third of my life being personal and family time, a third work and a third charity. I'm still a 16 hour a day person - but it's a really balanced 16 hours."

Largely because of his own life experiences, Mike still has something of a fascination with failure and turning the negative into something good.

"I have long harboured the notion that failure is not a bad thing. In fact, it is a very important part of our life journey," he says.

"Failure teaches you some of the most important lessons you will ever learn and if you are attuned to these lessons you will emerge a stronger, wiser and more resilient person - and be equipped with all the ingredients for success."

His ambition is to help others achieve their goals by sharing his stories and experiences through inspirational public speaking, and personal and professional mentoring.

It is evident from our conversation that Mike is a great believer in practising what he preaches. "You should live the life that you want to talk about and you should be the success that you advise on," he says.

And the strapline that underpins it all? "Businesses need to be more charitable and charities need to be more business-like," he replies.

We could have chatted for longer but I realised time was pressing and I now had my own goals to set and a strategy to plan. It was one of those inspirational interviews. And I left with what Mike likes to call his business card - a copy of his book Failure Breeds Success.

All fracked up

Sooner or later if the government’s plan comes off there will be a shale gas fracking site near you. Or you will have a friend or family member who lives near one.

That’s because around 3,000 wells could be drilled at more than 1,000 sites across the country in order to deliver up to a fifth of the country’s annual gas demand to an increasingly power hungry society - welcome to Fracking GB plc!

Today the government began a new round of licensing for onshore oil and gas, which opens up around half of the UK to potential fracking, including national parks in ‘exceptional circumstances’.

The licences are the first step towards exploration but firms will also have to obtain planning consent, permits from the Environment Agency and a sign-off from the Health and Safety Executive.

Fracking involves blasting water, chemicals and sand at high pressure into shale rock formations deep under ground to release the gas held inside.

In announcing the so-called 14th onshore licensing round, Business and Energy Minister Matthew Hancock said: "Unlocking shale gas in Britain has the potential to provide us with greater energy security, jobs and growth.

"We must act carefully, minimising risks, to explore how much of our large resource can be recovered to give the UK a new home-grown source of energy."

Today’s Guardian newspaper reports the government has committed nearly £2.5m of public money to an office to encourage fracking - before a single home has been powered by shale gas.

David Cameron has said the UK is going "all out for shale", with his government offering tax breaks to fracking companies and promising local authorities they will be able to keep 100% of the business rates from fracking operations, rather than 50% as before.

Previously unreleased figures show that the Office of Unconventional Gas and Oil (Ougo) - set up in March 2013 to encourage the development of shale gas and oil and coal bed methane - has already spent £568,000 and has been awarded a budget of £1.8m for this financial year.

There are already people living near fracking sites in the north of the country whose homes have been blighted - making insurance difficult and expensive, and significantly reducing property values.

"In pushing forward with their fracking fantasy, Cameron and co are riding roughshod over the climate science," said Natalie Bennett, leader of the Green Party.

"The science overwhelmingly indicates that 80% of known fossil fuel reserves need to be left underground if we are serious about meeting internationally agreed climate commitments."

She said fracking would add to the huge financial risk of the carbon bubble and called for the use of renewable and conservation technologies to build a sustainable energy policy.

"We need a government that doesn’t want to sacrifice our homes and communities for the profits of oil and gas firms while ignoring the pressing reality of climate change," she added.

The renewable wind power industry has had to deal with a broad range of challenges, particularly visual impact, and so far this doesn’t seem to be on the shale gas radar.

But type ‘shale gas rig’ into an internet search engine and select 'images' to see a taster of what might actually be in store for any community where drilling might take place.

We're likely to see the industrialisation of tracts of the British countryside, gas flaring in the home counties and a steady stream of trucks carrying contaminated water down rural lanes.

Production rates for the UK are expected to be lower than in the US because of lower pressure in UK basins, while costs might be higher because of demanding local environmental standards and the proximity of populated areas.

Analysis by Carbon Tracker estimates that if we are to contain greenhouse gas emissions at a level that preserves a reasonable chance of remaining below the 2C of global average temperature increase (considered a critical danger threshold), then four-fifths of known fossil fuel reserves need to remain locked in the ground.

The official Committee on Climate Change has warned that in the context of the UK’s legally binding climate-change targets, a new ‘dash for gas’ should be Plan Z, not Plan A.

All this makes for a risky backdrop to shale gas development in this country, which the Government seems determined to ignore in its public pronouncements and new round of licensing.

The industry will require major investment to get going and investors will need to be patient in getting a return, as going through the planning process and exploratory drilling will take years of expensive development before commercially useful quantities of gas are produced.

And no one really knows how much of gas can be got out, or how much that will cost both financially and to the environment at large.

Add to that the expectation that it will not in reality reduce energy prices, then the case for shale gas looks a lot more risky than proponents and the Government is suggesting.

The shale gas narrative and tax breaks presented by George Osborne a year ago are also, in part, based on the fear of being 'left behind'.

At the time Osborne said that a technological revolution based on government "getting out of the way of progress" is what we need. He couldn't be more wrong.

Where the country is being left behind, however, is in the development of new environmental technologies, including renewables and carbon capture. If we are to keep up in these areas, perhaps with some gas in the mix, it requires clear policy and leadership.

You can get away with small government on some issues - but not when it comes to energy. The UK needs a clear framework and strategy that sets out how we will secure our energy needs while meeting environmental goals. Right now we don't have that.

The current UK government - initially hailed by Cameron as ‘the greenest ever’ - is a liturgy of broken promises and short-term opportunism.

When it comes to energy policy and our long-term future it seems that little George has no idea. And neither has little Britain.

Global connections

As temperatures across the UK soared again this week it is worth taking note of how meteorological events in one part of the world can trigger weather on the opposite side of the globe.

Last weekend the UK recorded a total of 62,277 lightning strikes as storms moved in from Spain and France.

This followed a mini heatwave which enveloped most of the country, bringing with it temperatures in the low 30s and by far the hottest day of the year so far.

And all this was because of a storm thousands of miles away - super typhoon Negouri which had been churning across the north west Pacific in the first week of July.

As well as bringing strong winds and heavy rain to Japan it also dragged a mass of tropical air northwards and gave the jet stream a kick in the process.

That set off a ripple effect along the jet stream, running across the Pacific and extending its influence out across the Atlantic, forcing the jet stream there to swing northwards across Europe.

Super typhoon Negouri photographed by astronauts on the Space Station.

This is what allowed the exceptionally warm and humid air - known as a Spanish plume - to spread up and across the UK, bringing a brief heatwave before breaking down with severe thunderstorms.

So, a storm over the north west Pacific can set off thunderstorms 10 days later some 10,000 miles away - illustrating in a very real way how the weather in one part of the globe is often directly influenced by what is happens elsewhere.

We’ve also had news this week - data released by NOAA (the National Oceanic and Atmospheric Administration) - that last month was Earth's warmest June since records began in 1880. It marked the second month in a row the world has set a warm-temperature record.

The average temperature over global surfaces for June 2014 was 1.3 degrees above the 20^th century average of 59.9 degrees. In May, the Earth's temperature was 1.33 degrees above the average of 58.6 degrees.

"The warmth was fueled by record warm ocean temperatures," explained Jessica Blunden, a NOAA climate scientist.

"Large parts of the Pacific Ocean and most of the Indian Ocean hit record-high temperatures or were much warmer than average for the month."

Most of the world's land areas saw warmer-than-average monthly temperatures, with record warmth measured across part of southeastern Greenland, parts of northern South America, areas in eastern and central Africa, and sections of southern and southeastern Asia.

Every continent except Antarctica set temperature records and overall Earth's land areas in June were the seventh-warmest on record. It was also the 352nd consecutive month that the global temperature was above average.

So far, this year is tied with 2002 as the third warmest year on record, with a global temperature about 1.21 degrees above average.

According to NOAA, the last below-average global temperature for June was in 1976 and the last below-average global temperature for any month was February 1985.

It seems likely more records will be broken in the coming months as global warming combines with an emerging El Niño (see Countdown to El Niño).

NOAA currently puts the chance of El Niño forming at about 70% during the northern hemisphere summer and close to 80% during the autumn and early winter.

What's in a name?

British astronaut Tim Peake has named his mission to the International Space Station (ISS) next year after a book by Sir Isaac Newton.

But the name Principia - which refers to Newton's book of mathematical principles Philosophiae Naturalis Principia Mathematica - could turn out to be a pronunciation nightmare.

More than 4,000 people came up with possible names for the mission earlier this year and Principia was suggested 20 times.

When the winning name was revealed yesterday by those who had made the suggestion the ‘ci’ was pronounced with a ‘k’ sound (PrinKipia), in-line with the classical pronunciation of Latin.

Newton himself, an adept Latinist, would probably have pronounced it the same way but modern studies of Newton generally refer to the work as 'PrinSipia'.

Adhering to strict Latin pronunciation standards of old for a 21^st century space mission might seem a little irrelevant today - so which way do we go?

Like et cetera, the title of Newton's work has been pretty much absorbed into English and the ‘s’ version flows more naturally in the context of other English words and modern usage.

Principa set out the laws of motion and gravity more than 300 years ago and Major Peake chose the name in honour of its author Sir Isaac Newton, Britain's greatest scientist.

Tim will be launched from Russia’s Baikonur cosmodrome in Kazakhstan in December 2015 and he will spend six months in orbit carrying out scientific and medical experiments.

One of his aims is to inspire children during his stay in space, in particular by promoting healthy eating.

"I am delighted with this name that honours one of Britain’s most famous scientists," Tim said.

"Our planet Earth is a precious and beautiful place and we all need to safeguard it. I hope it will also encourage people to observe the world as if for the first time - just as Isaac Newton did."

Each time an ESA European astronaut prepares to go into orbit it is customary for the public to help choose a mission name.

Names that reflect an astronaut's nationality are encouraged - but they should also have a wider European flavour and be easy to pronounce.

Previous mission names have included Marco Polo (Roberto Vittori, Italy), Delta (Andre Kuipers (the Netherlands), Celsius (Christer Fuglesang, Sweden), Cervantes (Pedro Duque, France), Esperia (Paulo Nespoli, Italy) and Blue Dot (Alexander Gerst, Germany).

Viewers of the BBC children's programme Blue Peter will be invited to design the mission patch for the Principia mission in a competition to be launched in September.

The pronunciation conundrum is, perhaps, a little unfortunate for what is designed to be a popular mission bringing space to a new audience in the UK.

Time will tell exactly how the name of Britain’s most exciting space mission to date will be pronounced - and whether modern usage or tradition will win the day.

Government passes wind

Photo: Clive Simpson

British government policies are failing to support renewable energy despite more of the country’s electricity than ever before coming from renewable sources in the first part of the year.

Statistics from the Department of Energy and Climate change (DECC) reveal almost one fifth of electricity generated in Britain came from wind farms or other green technologies in the first three months of 2014.

New wind farms, strong winds and a good winter for hydro power plants sent renewable energy generation surging to 19.4% of all electricity from January to March.

The power produced was enough for about 15 million homes during the quarter and the figure is up from about 12% compared to the same period last year.

The figures were welcomed by green energy entrepreneur Dale Vince, founder of Ecotricity*, but he warned that government policies would severely limit further expansion of green power generation.

"Making our own energy here in Britain from green sources is the only way to keep our energy bills down and meet our climate targets," he said.

"To see Britain 20% powered by green energy is the first quarter of this year is fantastic - we've come a long way in a few years.

"Unfortunately we may not get much further with this government which is set firmly against the green energy industry and is in favour of fracking and nuclear power."

The DECC data reports the total amount of electricity generated by all forms of renewable power reached 18.1 terrawatt hours in the first three months of this year - up 43% on the same period last year.

Across the whole of 2013, the amount of electricity generated from renewable energy sources, including solar, hydro and biomass, was up by 30% on 2012. Offshore wind rose the most – by 52% – but solar was also up by 51%, while hydro generation fell by 11%, reflecting lower rainfall.

The DECC data reveals that the price of electricity for domestic customers was up by 5.9% in real terms quarter on quarter – the same figure as recorded for industrial electricity prices.

Jennifer Webber of RenewableUK, the renewable energy trade association, said: "Onshore wind is delivering today and it is deeply illogical to talk about limiting its potential.

"The government would have been even further behind its energy targets without the strong performance of wind last year. That's why we need to ensure that there's continued investment in both onshore and offshore wind."

When it comes to power generation we certainly live in a topsy turvy world.

Already this month more than 100 right-wing Conservative MPs have signed a letter urging the prime minister to further cut subsidies to onshore wind farms – beyond the planned 10% reduction already announced.

Apart from arguments over cost subsidies, the most common objection to wind turbines is they spoil the view. This despite much of our countryside having been blighted for years by countless miles of ugly power pylons and electricity cabling.

Yet, compared to a fracking well (coming soon to a location near you) or pollution spilling from a gas-fired power station, the symmetric beauty of wind turbines appear serene and unobtrusive.

Where prejudice - and the ‘need’ to preserve previously unremarkable or average ‘views’ - trump the very real needs of energy provision and protecting our future it is surely time to look at things with a new perspective?

Ed Milliband, leader of the Labour party, said in London yesterday that the country has a "decades-long problem" of short-term decision-making by successive governments.

Coherent long-term strategies are desperately needed in many areas and nowhere is this more important than in national energy policy and the renewables market.


*Ecotricity, one of the country's small energy suppliers is based in Stroud, Gloucestershire, and is the UK's leading supplier of green energy. It started supplying its customers with 100% green electricity from August 2013 and, according to its annual Progress Report, now sources ‘a unit of 100% green electricity' from its own windmills and sun park, or from the wholesale market, for every unit of electricity its customers use.

Factory food

Tournaments like the World Cup often serve as a reminder that our different languages and cultures across the globe remain distinctive and individual.

But when it comes to what we eat there is growing evidence that traditional diversity is being eroded.

Flicking between TV channels during mundane moments of the Germany versus Algeria World Cup match last evening I came across an interesting documentary on Channel 4.

‘The World’s Best Diet’ was a compelling exploration of the dietary habits of people all over the world, ranking the best and worst diets and asking what we should be eating.

It revealed how eating habits across the globe have transformed over the last 50 years - and how this has affected our health.

For the record England came in at number 34 of the 50 nations surveyed. And top of the diet pops was Iceland, where fresh fish is a staple.

I was surprised to learn that inhabitants of the Marshall Islands in the remote Northern Pacific now have the worst ranked diet - and highest rates of death by diabetes - largely because their traditional farming has been replaced by additive-filled American imports.

Overall, the message of the programme was clear - stay away as much as possible from all kinds of processed food.

But somehow all this talk of healthy eating seems to have the opposite effect and I just can’t resist the urge to pop out and buy a Snickers bar - or should that be a Marathon?

Blue sky thinking

Researchers concerned about the climate change potential of condensation trails in the sky caused by aircraft have suggested the impact could be reduced by re-routing flight paths.

Contrails - a cirrus-like cloud - are a relatively new type of high-level cloud that appear in the wake of high-altitude aircraft as water vapour from engine exhausts coalesces.

They can be up to 150km in length and last up to 24 hours, forming when planes fly through very cold and moist air causing engine exhausts condense into a visible vapour.

Founder of The Cloud Appreciation Society Gavin Pretor-Pinney writes in The Cloudspotter’s Guide that we may be surprised to learn that contrails are even classified as clouds.

But clouds they are - and the only difference between them and what nature produces is that contrails are definitely man-made.

Contrails reflect sunlight back into space and so have a cooling effect - but they also trap infrared energy in the atmosphere, which adds to global warming.

Scientists at the University of Reading in the UK have been looking at how the warming impact - which is more significant overall than the cooling - could be reduced by altering the flight paths of long and short haul aircraft.

Previous work has suggested that planes could fly at lower altitudes to limit the trails but this would burn significantly more fuel and adding to CO2 emissions overall.

The Reading study attempted to see if the benefits of curbing contrails would outweigh the extra fuel burned if flights were re-routed whilst at the optimum flying altitude.

They suggest that avoiding the creation of a major contrail on a flight between New York and London would only add 22km to the journey but could curb the flight’s warming impact.

"You think that you have to do some really huge distance to avoid these contrails," said Dr Emma Irvine, the study’s lead author.

"But because of the way the Earth curves you can actually have quite small extra distances added onto the flight to avoid some really large contrails."

The researchers found that short haul aircraft are more fuel efficient and can add up to 10 times the length of the contrail to their journeys and still reduce overall warming potential.

So, if a flight from the UK to Spain is predicted to create a 20km long contrail, as long as the plane flew less than 200km extra to avoid it, the overall warming impact would be reduced.

But for large planes on longer routes over oceans and unpopulated areas - which offer more flexibility to minimally alter flight paths - this reduces to three times the contrail length.

"The key things you need to know are the temperature of the air and how moist it is, these are things we forecast at the moment, so the information is already in there," said Dr Irvine.

On average, 7% of the total distance flown by aircraft is in the type of air where long lasting contrails form but none of the calculations on the impact of aviation on global warming currently include them.

The carbon restrictions being introduced from 2017 for long haul flights originating or arriving in the EU will not include this significant source of warming from aviation.

"The mitigation targets currently adopted by governments all around the world do not yet address the important non-CO2 climate impacts of aviation," said Dr Irvine.

"Contrails may cause a climate impact as large, or even larger, than the climate impact of aviation CO2 emissions.

"We believe it is important for scientists to assess the overall impact of aviation and the robustness of any proposed mitigation measures in order to inform policy decisions. Our work is one step along this road."

Four years ago when flights across Europe were grounded - due to the dust cloud created during the eruption of an Icelandic volcano - our skies and sunsets could be viewed without visible signs of human intrusion.

Contrails and their delicate linear patterns often add a seemingly innocent beauty to the skies above but Pretor-Pinney is not so sympathetic and describes them as "the bastard sons" of the cloud family.

"They may cut dashing figures across the rosaceous autumn evening but these icy swathes of progress must be the writing on the sky for cloudspotters and everyone else besides," he says.

New North Sea harvest

Just as the UK's gas and oil bonanza is drawing to a close it seems that the often maligned North Sea off the east coast of Britain is about to deliver again.

This time the harvest will be in the shape of electricity from the gusty winds that ply relentlessly across the busy stretch of water.

The government announced today the go-ahead for one of the world's largest offshore wind farms that is set to be built off the coast of East Anglia.

‘East Anglia One’ will cover an area of 300 square kilometres in the southern North Sea and support almost 2,900 jobs and is expected to generate enough electricity to power the equivalent of 820,000 homes.

It could also pump over £520 million into the region’s economy and today’s announcement is an important milestone for the 50/50 joint venture between ScottishPower Renewables and Vattenfall,.

Construction is expected to start in 2017 with offshore installation commencing the following year and generation starting in 2019.

Initial plans were to install up to 325 offshore turbines in a zone some 43 km off the coast but the use of larger turbines means that only around 240 will likely be needed to deliver the same 1.2GW of capacity.

UK energy secretary Ed Davey said: “East Anglia and the rest of the UK have a lot to gain from this development. The project has the potential to inject millions of pounds into the local and national economies, and support thousands of ‘green’ jobs.

“Making the most of Britain’s home grown energy is crucial in creating job and business opportunities, getting the best deal for customers and reducing our reliance on foreign imports.”

RenewableUK’s chief executive Maria McCaffery described it as “a huge confidence boost” for the UK’s entire offshore wind sector.

“Our world-beating offshore wind industry is set to more than treble in size by the end of the decade – projects like this will help us to maintain our global lead,” he said.

“This marks the start of what is set to be one of the world’s major green energy infrastructure developments. It is the first of six projects within the same zone with a combined capacity of up to 7.2 gigawatts, enough to power more than 4.6 million British homes.

The government announcement stressed that the new wind farm would be ‘significantly larger’ than the the London Array, currently the biggest wind farm in the world.

ScottishPower Renewables and Vattenfall will now accelerate supply chain contracts and start detailed negotiations to determine which ports could best support the project.

Geographically, the North Sea - most of which has an average depth of around 94m - is on the European continental shelf and, strictly speaking, is part of the Atlantic ocean.

It lies between Norway and Denmark in the east, Scotland and England in the west, and Germany, the Netherlands, Belgium and France in the south.

Drilling for oil - in fields mostly owned by the UK and Norway - began in the 1960s and led to still on-going arguments between England and Scotland about how revenue from the oil should be spent.

In contrast to oil and gas, wind power is both sustainable and clean in terms of emissions and is now recognised as one of the world's fastest growing energy sources,.

Harnessing its power to make electricity won’t solve the world’s climate change problems but developments like East Anglia One are definite steps in the right direction.

Countdown to El Nino

Meteorologists and climate scientists say the world is likely to enter another El Niño weather event by this autumn upsetting 'normal' weather and driving up global temperatures further.

El Niño’s most notable characteristic is the presence of extra-warm surface water in the central and eastern equatorial Pacific ocean which tends to lead to greater average global temperatures.

Climate scientists saw a chance for 2014 to be a record temperature year even before news about the likely development of El Niño conditions - simply because temperatures continue to tick upwards.

“I would have predicted a likely top five if asked at the beginning of this year and the incipient/potential El Niño strengthens that,” said Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies, one of the leading agencies that tracks global temperatures and ranks them by year.

“We saw record global temperatures in 1998, 2005 and again in 2010 when ongoing global warming was positively reinforced by El Niño events,” he added.

“There is a good chance we will see a global temperature record this year or next if a substantial El Niño event takes hold.”

Data from ocean observing satellites and other ocean sensors indicate that El Niño conditions appear to be developing in the equatorial Pacific Ocean.

Conditions in May 2014 bear some similarities to those of May 1997, a year that brought one of the most potent El Niño events of the 20th century.


The maps above show the ten day average of sea surface height centred on 2 May 1997 (left), and 3 May 2014. Darker shades indicate where the water is warmer and above normal sea level. Shades of blue-green show where sea level and temperatures are lower than average. Normal sea-level conditions appear in white. The 1997 map is from data collected by the TOPEX/Poseidon satellite, while the 2014 data is from the Ocean Surface Topography Mission/Jason 2 satellite.

During an El Niño, easterly trade winds in the Pacific falter and allow giant waves of warm water - known as Kelvin waves - to drift across from the western Pacific toward South America.

Surface waters in the central and eastern Pacific become significantly warmer than normal, altering weather patterns and affecting fisheries along the west coasts of the Americas. El Niño can also have a significant influence on weather and climate far from the tropics.

Sea surface height is a good indicator of the amount of heat stored in the water. As the ocean warms, the surface rises; as it cools, its falls. This is due to thermal expansion and contraction; the molecules in warmer water are farther apart than in cooler water.

Above-normal sea surface heights in the equatorial Pacific indicate El Niño conditions, while below-normal heights indicate La Niña.

“What we are now seeing in the tropical Pacific Ocean looks similar to conditions in early 1997,” said Eric Lindstrom, oceanography programme manager at NASA.

“If this continues, we could be looking at a major El Niño this autumn. But there are no guarantees.”

Observations from a network of sensors within the Pacific Ocean support the satellite view, showing a deep pool of warm water that has been sliding eastward since January.

The years 1997/98 brought El Niño out of the scientific literature and onto the front pages and evening newscasts. It was one of the strongest El Niño events observed, with extreme weather impacts on several continents.

North America had one of its warmest and wettest winters on record, particularly in California and Florida. Peru, Mexico, and the rest of Central and South America endured devastating rainstorms and flooding. Indonesia and parts of Asia saw disastrous droughts.

Scientists at the Climate Prediction Center of the National Weather Service (NWS) announced in early May that they foresee a 65 percent chance of a transition to El Niño in the summer of 2014.

"There remains uncertainty as to exactly when El Niño will develop and an even greater uncertainty as to how strong it may become," NWS reported.

All this might just be bad news for climate change skeptics. We've all heard by now the claim that global warming has ‘stopped’ or is ‘slowing down’ but this assertion often takes the very warm year of 1998 as the starting point.

By deliberately beginning with a hot year it can be made to look as though global temperatures aren't rising so fast.

Global temperature anomalies from 1950-2013 from World Meteorological Organisation, with years beginning with El Niño conditions in red and years beginning with La Niña conditions in blue.

You could think of annual global temperature variations as like waves on a rising tide. The rising tide is global warming and the waves are the shorter-term natural fluctuations related to phenomena like El Niño (or its flip-side La Niña), which warm (or cool) the globe by fractions of a degree.

The reality is that, as the World Meteorological Organisation (WMO) notes, each of the last three decades has been warmer than the previous one - culminating with 2001-2010 as the warmest decade on record.

Every time the world sets another temperature record, the global warming ‘slow down’ message becomes less compelling and as we enter another El Niño the climate change skeptics may finally be running low on options.

Either they finally accept the overwhelming body of evidence that global warming is real or they can come up with a new cherry-picked counter argument. Have a guess which one they'll choose - for now, at least?

Tractors on the beach

The seaside town of Cromer lies on the UK’s east coast. Perched on the edge of crumbling north Norfolk cliffs, it is famous for tasty crabs, wide open beaches and a traditional Victorian pier complete with theatre and a seaside special variety show.

Its unique geographical location jutting out into the North Sea means that on a blue sky summer’s day you can watch both sunrise and sunset over the ocean.

This does imply, of course, that you are diligent enough to rise exceptionally early and still be wakeful enough at the other end of the day to repose on the pier, perhaps with beer in hand.

There is no quay-side or harbour at Cromer so the fishing boats are gathered on the shingle beach against the sea wall, each with its own tractor and boat trailer.

At the end of the 19th century, the beaches to the east and west of the pier were crowded with fishing boats. Now, you will see only a dozen boats which ply their trade from the east beach.

Crabs - dressed or undressed according to your state of desire - can be bought direct from local fishermen, or enjoyed at local restaurants in salads, tarts and sandwiches.

Today, it is not the crabs themselves that grab our interest but the rusty, salt-laden army of ancient and colourful tractors that line the beach head.

They are adorned and customised with all manner of fixtures and fittings - from plastic deckchairs as replacement seats to makeshift gear sticks and lashed on tarpaulins to keep the worst of the elements out of the workings.

Most look so rusted through with salt it seems a miracle their sand-blasted engines would ever start.

But somehow they defy mechanical odds and, with crabbing boats in tow, continue to chug across the shingle beach to the water’s edge and back.

The photos below are a selection from the Lighthouse Keeper's visit to Cromer on a sunny and warm afternoon a few days ago. All were taken with a Nikon D70 SLR camera.

LED lighting's dark side

New LED street lighting being installed by councils throughout the country to save money and cut carbon emissions could mean more sleepless nights and ultimately be bad for our health.

A study by the Campaign for the Protection of Rural England (CPRE) says some eco-friendly low-energy LED (light emitting diode) street lighting creates unnecessary glare and might have serious effects on people’s well-being.

Light pollution expert Martin Morgan-Taylor has called for more research into which wavelengths, levels and durations of lighting pose health threats - and how this compares with modern lighting practices.

The lecturer - from Leicester’s De Montfort University - says medical research is increasingly linking LED lighting with more serious health issues such as cancer and depression.

"Artificial lighting is known to have negative effects on human health and well-being if sleep is disrupted by bright light shining into bedroom windows," he said.

"What we know is that ‘white’ or ‘blue-rich’ lighting - which mimics natural daylight - is being increasingly used at night.

"This type of light suppresses the production of a circadian rhythm hormone called melatonin, which is believed to be a powerful anti-oxidant that helps to ward off some cancers," he said.

The CPRE report, ‘Shedding Light – a survey of local authority approaches to lighting in England’ is the first piece of research to ask councils how they control light pollution.

Councils are urged to give ‘careful consideration’ to the type of LED lighting they use and weigh the potential impacts that higher temperature blue-rich lighting has on ecology and human health.

The report says authorities across England could be doing more to reduce the impact of light pollution and be saving hundreds of thousands of pounds a year in the process by using dimming schemes.

It also urges councils to preserve dark skies by having a ‘presumption against’ new lighting in existing dark areas and preventing ‘inappropriate and badly designed development’ that masks views of the night sky.

But according to the survey of 83 local authorities fewer than two thirds of councils in England are actively seeking to minimise the impact of bad lighting - despite recent changes to planning laws which encourage them to do so.

The CPRE also recommends new street lighting should be tested ‘in situ’ before schemes are rolled out across wider areas to ensure that it is the minimum required for the task and does not cause a nuisance to residents.

Street lighting in England costs councils around £616m a year and can account for up to 30% of their carbon emissions.

The CPRE study reveals that despite the number of people living with severe light pollution around the country growing more than a third of councils have no formal policy in place.

Almost half of councils responding said they were involved in dimming street lights in their areas and a third say they are now switching off street lights - typically between midnight and 5am.

The research found dimming schemes are significantly more popular with residents than switch off schemes - with 68 per cent of respondents saying local communities had been very supportive.

Some council schemes to replace old-style sodium ‘orange’ street lighting with new LED lamps have attracted criticism from nearby residents.

Last month people in a west London borough complained that new LED street lamps were so bright they were no longer getting a good night's sleep.

Hounslow council started using the lights as part of a multi-million pound improvement scheme but people living close to the new LED lighting described it is ‘like living on a floodlit soccer pitch’.

Elsewhere, Leicester city council is updating 32,000 of its 37,000 street lights as part of a commitment to reduce the council's carbon footprint by 50% before 2025.

The three year £13.9m project began in March 2013 and will contribute an estimated saving of 5,350 tonnes of carbon emissions per annum.

It includes a Central Management System (CMS) for remote control of lighting levels in specific areas, allowing dimmed lighting, for example, in the early hours before dawn.

The council says replacing its existing stock with LED lighting will reduce energy usage and carbon emissions by over 40% compared with current levels, saving electricity charges (at 2013 prices) of £0.84m a year.

Using a CMS should provide a further 17% reduction, increasing the overall savings to 57% of current energy usage and carbon emissions, and slashing a total of £1.2m off its annual electricity bill.

where new white LED lighting has already been installed.

Other councils are, however, taking a more cautious route. In Essex, the streets have been equipped with one of the world’s largest wireless street lighting control systems.

Around 125,000 of the county’s street lights have been wirelessly linked, allowing centralised control and fault detection.

The council expects to reduce the energy cost of street lighting by around £1.3 million per year and to cut annual carbon emissions by over 8,000 tons.

Earlier this year Trafford council in Manchester delayed its £9.3m scheme to replace all its 27,000 street lights after a resident threatened High Court action.

Simon Nicholas, a chartered engineer and businessman, raised concerns that new LED lighting had the potential to cause health problems.

"We're breaking new ground here and new evidence is emerging all the time," he said. "The council has not fully taken these studies into account."

Mr Nicholas claimed some councils are not looking at the bigger picture ."LEDs are currently on an exponential curve in terms of development," he said.

"In five years’ time we may well have really good LED street lights. Anyone charging in now is making a huge mistake."

Emma Marrington, CPRE Dark Skies campaigner and author of the ‘Shedding Light’ report, said: "Many local authorities are taking steps in the right direction but much more can be done.

"We urge councils to do more to control lighting in their areas and ensure that the right lighting is used only where and when it is needed."

She said the research had revealed no evidence to support the fear that adjusting or dimming street lights impacted on public safety.

"We're not advocating changes where they're not appropriate - but why shine bright lights on residential streets, quiet roads and open countryside throughout the night when it's not needed?

"Genuine dark starry nights are becoming harder and harder to find which is why councils should take action to control it now. Light pollution blurs the distinction between town and country, ruins the countryside's tranquil character and denies us the experience of a truly starry sky."

Turning up the heat

One day in the future the Wash will extend inland as far as the cities of Peterborough and Cambridge. That means much of the Fens - including the market town of Spalding where the Lighthouse Keeper currently resides - will be under water.

And, if as expected, sea levels rise significantly the story will be repeated throughout the country - not to mention key cities and settlements around the world.

On the English south coast, the naval bases of Portsmouth and Plymouth will largely disappear. Further north, Hull will be lost, as will much of south Yorkshire.

Middlesbrough would succumb to the waves and, in the northwest, Chester would be flooded. In the east, rising sea levels will eventually claim Felixstowe, Southend and Great Yarmouth.

Around London, the Thames estuary would probably expand to three or four times its current breadth, eliminating most of Dagenham, Stratford and Ilford in the process.

And, unless huge flood defences that dwarf the current barriers are created, the whole of central London would become very seriously water-logged.

But we have to be honest. Despite the mounting evidence are we capable of mitigating such an impending disaster?

Part of the problem is that the world’s own climate disaster movie will be years in the making and is set for release only on an indeterminable date in the future - a distant event horizon.

The worst effects of climate change and global warming for most of us may be perhaps still some 50, 100 or 150 years hence.

But what we don’t know is whether this estimated timescale is fixed. Or will significant trigger points - like the melting of polar ice - have an exponential and accelerating effect?

If the recent European elections are anything to go by climate change, energy policy and the environment will likely disappear into the murky background of science denial and fear in Europe of far-right politicians before the UK’s national elections next spring.

Earlier this year, amid growing warnings about a potential link between global warming and extreme UK weather, Ed Davey, the energy secretary, raised concerns that political consensus about the need to tackle climate change was in danger of breaking down.

He said that the actions of climate deniers - and those in the Conservative and UKIP parties who try to discredit the science - is "undermining public trust in the scientific evidence for climate change".

Criticising those who seize on "any anomaly in the climate data to attempt to discredit the whole", Mr Davey added that "we can see around us today the possible consequences of a world in which extreme weather events are much more likely".

A joint report this spring from the UK Met Office and the Centre for Ecology and Hydrology, entitled ‘The Recent Storms and Floods in the UK’, points out that the 12cm rise in sea level over the 20th century has already exacerbated coastal flooding.

It goes on to say that a further rise of between 11cm and 16cm is expected by 2030, two-thirds of which is attributable to the effects of climate change.

Last month scientists at a NASA conference announced they had collected enough observations to conclude that the retreat of ice in the Amundsen sea sector of West Antarctica was unstoppable.

Its disappearance will likely trigger the future collapse of the rest of the West Antarctic ice sheet - which brings with it a global sea level rise of between three and five metres.

Eventually, rising sea levels will displace millions of people worldwide and one headline in a US magazine reporting the NASA conference ran the headline - ‘This Is What a Holy Shit Moment for Global Warming Looks Like’.

For those who have seen the recent film ‘Noah’ starring Russell Crowe, based on the story of a Biblical flood, there might be parallels to be drawn.

"For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark; and they knew nothing about what would happen until the flood came and took them all away."                           Matthew 24:38-39

Like the people of Noah’s time, we remain wilfully oblivious to the looming human ecological catastrophe.

Are we prepared to accept huge changes in living standards merely to limit - rather than halt - the rise in temperatures and ensuing problems?

And where capitalism rules, can anyone persuade our politicians to put the future ahead of the present, apart from in a sound bite?

Sometimes the task ahead feels as hopeless as arguing against growing old. This is, indeed, a ‘holy shit’ moment for the world and it seems like something of a miracle is needed.
