Light pollution 'saturates' UK's night skies


Half of the UK's population cannot see many stars because the night skies are still "saturated" with light pollution, campaigners have warned.

Some 53% of those who joined a recent star count failed to see more than 10 stars in the Orion constellation.

That had decreased only very slightly from 54% since 2007, the Campaign to Protect Rural England and the Campaign for Dark Skies said.

The problem remained despite attempts to curb street lighting, they said.

They said that in 2010, local authorities collectively spent more than £500m on street lighting, accounting for 5% to 10% of each council's carbon emissions.

A number of councils have tested schemes to switch off or dim street lights when they are not needed, although the trials have often proved controversial with residents.
Sleeping patterns

The information was gathered as part of the annual Star Count survey, which was held across two weeks in January and February this year.

Almost 1,000 people in different locations around the country took part.

Participants were instructed to pick a clear night to count the number of stars in the constellation of Orion.


"Many children growing up today will never see the Milky Way; never see the unimaginable glory of billions of visible stars shining above them” - Bob Mizon Campaign for Dark Skies

Fewer than one in 10 said they could see between 21 and 30 stars, and just 2% of people had truly dark skies, seeing 31 or more stars.

Emma Marrington, a rural policy campaigner for the CPRE, says: "When we saturate the night sky with unnecessary light, it damages the character of the countryside and blurs the distinction between town and country.

"But this isn't just about a spectacular view of the stars; light pollution can also disrupt wildlife and affect people's sleeping patterns."

Bob Mizon of the CfDS believes light pollution is a disaster for anyone trying to study the stars.

"It's like a veil of light is being drawn across the night sky, denying many people the beauty of a truly starry night.

"Many children growing up today will never see the Milky Way; never see the unimaginable glory of billions of visible stars shining above them," he said.

For the first time, national guidance has been issued by the government, to encourage local planning authorities to reduce light pollution through design improvements.

The National Planning Policy Framework, published at the end of March, states that by encouraging good design, planning policies and decisions "should limit the impact of light pollution from artificial light on local amenity, intrinsically dark landscapes and nature conservation".

"There is also a role for businesses to play in ensuring glaring lights and neon signs that light up the night sky are not left on unnecessarily” - Local Government Association

Ms Marrington from the CPRE welcomed the move, saying poor excuses for bad or excessive lighting were heard too often.

"Of course we need the right, well-designed lighting in the right places - and some areas need to be lit for safety reasons - but there should not be a blanket assumption that glaring lights are needed.

"The evidence gathered during this year's Star Count Week shows that we need to take action now to roll back the spread of light pollution."

The Local Government Association, which represents councils, said local authorities were "well ahead of the game on this issue".

"Over the past two years scores of local authorities up and down the country have been trialling the switching off and dimming of street lights late at night in quieter areas," it said.

However, it added, public safety had to come first and councils would not cut lighting if a large number of people were strongly opposed to the idea and there were genuine safety concerns.

It added: "There is also a role for businesses to play in ensuring glaring lights and neon signs that light up the night sky are not left on unnecessarily."

This is absolutely true. I've never seen the point of so many street lights.
People have headlights on their cars. If they can't drive safely using them, they really shouldn't be out at night.

When I go to Ireland, about ten miles out from town, the sky is fantastic on a clear night.
I could look at the stars for hours, if it wasn't for the feckin midges.

We could all learn some lessons from North Korea on this issue.

Yep. Can't see shit here. Even on a clear night there's a yellow glow that precludes any serious viewing or photography of the night sky.

Fortunate we're running out of power soon then isn't it? Apparently crime, at night, was sky high before the introduction of street lighting. Still being able to see the stars, when it isn't cloudy, will make up for your stolen television?

The is beautiful when you get away from the campfires, but beware the wolves.

Still even if we did turn off all the lights and preformed removal of the cranium from the rectum of most people, they'd still spend all night looking at phones, hair and shoes.

It's very hard to get totally away from light pollution down these parts - unless maybe it's some remote spot down on Romney Marsh.

During Earth Hour 2010, many Finnish cities switched off parts of the street lights. Then on one darkened road a girl got hit by a motorcycle and died.

The area where I live in Glasgow is filled (like most of Glasgow) with tenements. However since I am near Ibrox Park and Govan, it was traditionally a very violent area. I've lived here 16 years and seen too many assaults, attempted and murders. However some bright spark (I'm thinking Nicola Sturgeon, who despite here political ideology has been an exceptional MP) decided a few years ago to replace those urban violent orange streetlights with the energy saving blue/white streetlights.

The difference is remarkable, not only can I stand on the main road like it is daylight and see about 40/50% more stars, but since the installation of those lights 4 years ago there has not been as single serious incident outside of Friday and Saturday night closing time.

It's not the total solution to the problem, but a partial solution to two. Which I think better, personally.
