The odds are still against Scottish independence, but every vote will count

The closer the contest is, the more likely radical changes to the devolution settlement become.

Polls of the Scottish electorate currently show a healthy lead for those arguing against independence. But even if public opinion doesn’t shift significantly in the months ahead, every vote will be crucial in determining Scotland’s constitutional future after the referendum.

With Holyrood about to go into recess, it’s clear that if the referendum were held tomorrow there would likely be a clear victory for those arguing for Scotland to remain in the UK. Once we get back from the summer break, there will be a year left for both sides to make their case.

For those of us keenly watching every detail of the debate, it was surprising to read the First Minister’s interview in last week’s New Statesman in which he declared: "This is the phoney war. This is not the campaign." To some extent, he’s right, and all sides expect some movement in public opinion in the months ahead.

Salmond’s optimism is born out of a number of factors. He believes that on-going austerity measures, particularly cuts in welfare spending, will push voters towards voting 'Yes'. He will also have an eye on the outlook for the 2015 general election and hope that next year’s Commonwealth Games in Glasgow may engender feelings of Scottish nationalism in the same way that last year’s Olympics enhanced pride in ‘Britishness’ among many voters.

The main reason to suggest some shifts in opinion though is what our polls highlight about the number of people who are still to make up their minds. 'Undecided' voters come in three categories: those who tell us they may not vote if there were a referendum tomorrow (25 per cent of adults in our latest poll from May, including 2 per cent who tell us they definitely will not vote), those who would vote but are undecided (7 per cent) and those who lean towards one side but tell us they may change their minds before polling day (12 per cent). Taken together, this represents over four in ten Scots whose vote remains up for grabs and who will become an increasingly important group as the referendum comes into clear view.

This said, at present the odds remain firmly stacked in favour of the No campaign. This is because, although there are significant numbers of undecided and uncommitted voters, there is nothing in our polling to suggest that they are currently leaning towards voting Yes in sufficient numbers to make a decisive difference to the overall result.

In fact, analysis of these groups provides more comfort to those in the No camp. Among those who tells us they are uncertain to vote in the referendum, one in five, 20 per cent, would vote Yes while half, 49 per cent, would vote No, suggesting that a campaign to encourage participation is more likely to be beneficial those in favour of Scotland remaining in the UK. Those who tell us that they are undecided or may change their minds are more evenly split, with 38 per cent leaning towards Yes and 43 per cent towards No. The remainder cannot be even gently swayed either way at the moment.

So, assuming undecided voters do not begin switching to Yes in significant numbers in the coming months, the debate may begin to switch from who will win the referendum to the margin of victory and what that means for Scotland’s constitutional future.

Our polling suggests that a majority of Scots want some form of constitutional change. For instance, our June 2012 survey showed 29 per cent in support of the status quo, while more than two-thirds of voters (68 per cent) supported either full independence (27 per cent) or the 'Devo-Plus' proposals for greater powers being devolved to the Scottish Parliament.

We do not yet know what will happen to Scotland’s constitutional position in the event of a No vote next year. But it is possible that more radical and significant changes become more likely in a closely contested vote. That’s why every vote will be significant and strongly fought for in the run up to the referendum.

The deafening killer - why noise will be the next great pollution scandal

A growing body of evidence shows that noise can have serious health impacts too. 

Our cities are being poisoned by a toxin that surrounds us day and night. It eats away at our brains, hurts our hearts, clutches at our sleep, and gnaws at the quality of our daily lives.

Hardly a silent killer, it gets short shrift compared to the well-publicised terrors of air pollution and sugars food. It is the dull, thumping, stultifying drum-beat of perpetual noise.

The score that accompanies city life is brutal and constant. It disrupts the everyday: The coffee break ruined by the screech of a line of double decker buses braking at the lights. The lawyer’s conference call broken by drilling as she makes her way to the office. The writer’s struggle to find a quiet corner to pen his latest article.

For city-dwellers, it’s all-consuming and impossible to avoid. Construction, traffic, the whirring of machinery, the neighbour’s stereo. Even at home, the beeps and buzzes made by washing machines, fridges, and phones all serve to distract and unsettle.

But the never-ending noisiness of city life is far more than a problem of aesthetics. A growing body of evidence shows that noise can have serious health impacts too. Recent studies have linked noise pollution to hearing loss, sleep deprivation, hypertension, heart disease, brain development, and even increased risk of dementia.

One research team compared families living on different stories of the same building in Manhattan to isolate the impact of noise on health and education. They found children in lower, noisier floors were worse at reading than their higher-up peers, an effect that was most pronounced for children who had lived in the building for longest.

Those studies have been replicated for the impact of aircraft noise with similar results. Not only does noise cause higher blood pressure and worsens quality of sleep, it also stymies pupils trying to concentrate in class.

As with many forms of pollution, the poorest are typically the hardest hit. The worst-off in any city often live by busy roads in poorly-insulated houses or flats, cheek by jowl with packed-in neighbours.

The US Department of Transport recently mapped road and aircraft noise across the United States. Predictably, the loudest areas overlapped with some of the country’s most deprived. Those included the south side of Atlanta and the lowest-income areas of LA and Seattle.

Yet as noise pollution grows in line with road and air traffic and rising urban density, public policy has turned a blind eye.

Council noise response services, formally a 24-hour defence against neighbourly disputes, have fallen victim to local government cuts. Decisions on airport expansion and road development pay scant regard to their audible impact. Political platforms remain silent on the loudest poison.

This is odd at a time when we have never had more tools at our disposal to deal with the issue. Electric Vehicles are practically noise-less, yet noise rarely features in the arguments for their adoption. Just replacing today’s bus fleet would transform city centres; doing the same for taxis and trucks would amount to a revolution.

Vehicles are just the start. Millions were spent on a programme of “Warm Homes”; what about “Quiet Homes”? How did we value the noise impact in the decision to build a third runway at Heathrow, and how do we compensate people now that it’s going ahead?

Construction is a major driver of decibels. Should builders compensate “noise victims” for over-drilling? Or could regulation push equipment manufacturers to find new ways to dampen the sound of their kit?

Of course, none of this addresses the noise pollution we impose on ourselves. The bars and clubs we choose to visit or the music we stick in our ears. Whether pumping dance tracks in spin classes or indie rock in trendy coffee shops, people’s desire to compensate for bad noise out there by playing louder noise in here is hard to control for.

The Clean Air Act of 1956 heralded a new era of city life, one where smog and grime gave way to clear skies and clearer lungs. That fight still goes on today.

But some day, we will turn our attention to our clogged-up airwaves. The decibels will fall. #Twitter will give way to twitter. And every now and again, as we step from our homes into city life, we may just hear the sweetest sound of all. Silence.
