'Just do the weather': does it matter if TV weather presenters aren't experts?

This is an edited extract from The Weather Obsession by Lawrie Zion, published by Melbourne University Press.

When Olympic swimming champion Giaan Rooney was asked to fill in presenting the weather segment on Melbourne’s Channel Seven weeknight news program just before Christmas 2012, she was taken aback. She pointed out that she knew nothing about weather and that her credibility was in sport. “Don’t worry, just do the weather,” was the reply from the network. Six weeks later, the 30-year-old Rooney was invited to continue in the role, replacing the 52-year-old presenter and trained meteorologist David Brown, who had been presenting on Seven for 20 years.

As it turned out, Brown remained with the network and eventually went on to present the weather for Seven’s Sydney weeknight bulletin. But the switch from Brown to Rooney illustrates a dilemma that has never been resolved. Just who should present the weather on television?

Commenting on Rooney’s appointment soon after the announcement, the Sunday Herald Sun’s Susie O’Brien wrote:

…the old adage that people like a mature man to tell them the serious news and a pretty face to tell them the weather still seems to apply. The real question is why we need a nice-looking woman who isn’t a meteorological expert to tell us the weather at a time when climate issues have never been more important. The fact that we are still having these debates is a sign we have a long way to go. Sadly, I think we will continue to see women used as decorations on network TV for a while to come.

What O’Brien saw as an anachronistic decision needs to be understood in the context of the role of weather segments in television news bulletins, and the changing demographics of broadcast news audiences.

Weather presenters have long been a crucial component of any television news team, and are promoted as such. For many in the audience, they’ve also been the main conduit of weather information. Ten years ago 90% of Australians received at least some of their weather information from television. This has since fallen to 71%, according to a Bureau of Meteorology survey. But that’s still a lot of eyeballs. And with their segments usually perched at the end of bulletins, the extent to which weather presenters connect with viewers helps to determine whether their station can carry the valuable news audience over to the start of the next program.

When it comes to sheer numbers, TV news audiences may have generally held up well with older viewers, but younger viewers aren’t drawn to these programs to anything like the extent that their parents were. The result is that around half the audience is over the age of 50, and therefore more likely to go for the familiar than the experimental. So while the steady evolution of graphics means that weather reports look very different now from how they appeared in the early days of television, the format has remained more predictable than the weather itself.

We all know the ritual: What happened today? What will happen tomorrow? And beyond tomorrow? Across the country? If it’s a local bulletin the state and/or city forecast will precede the sign-off. As Channel Nine Brisbane news presenter Andrew Lofthouse has put it: “The weather reports are still one of the constant reassuring things that people can rely on.” This might partly explain why changes to who presents the weather attract so much attention within the media itself.

Despite an overall tendency to play it safe, what this actually means tends to fluctuate, with appearance, personality and specialist credentials all deemed to be relevant factors to varying degrees. As O’Brien put it in the context of Brown’s replacement by Rooney: “Presumably Channel Seven has tired of the serious approach and in the midst of falling ratings is going for the well-worn route of installing an attractive female to freshen things up.”

Hiring attractive women as weather presenters is a time-honoured global tradition. Writing about the history of TV weather in America, Robert Henson points out that it became clear in the 1950s that women could be accepted as weathercasters, as long as the focus was kept on clothing, hairstyle or anatomy. “So began the brief ascendancy of ‘weathergirls’, a term that speaks volumes about the differences in status between these women and their male counterparts in weathercasting.”

But while the weathergirl craze abated in the United States by the early 1960s, in Australia, where television had been introduced relatively recently, it was just beginning. In 1961, an item in the Bureau’s in-house publication, Weather News, noted that in Brisbane, “the majority of stations appear to favour the glamour-girl type of telecaster for weather presentations”, and that “Bureau staff have had the pleasure of indoctrinating and briefing two ‘Miss Australias’ and one ‘Miss Queensland’ in the short time that television has been operating in this State”. The background training included explaining the need for weather information to be presented seriously and faithfully, “and particularly for the more glamorous the need to submerge their glamour behind the prosaic highs and lows”.

In 1965, Melbourne’s Channel 9 hired model Rosemary Margan to present the weather. One evening in 1969, she appeared in a fur coat before stripping to a bikini during her live segment, sparking a steady stream of responses from viewers. In the 1970s, when searching for a replacement for the then pregnant Margan, the station hired the 15-year-old schoolgirl Kerry Armstrong, whose job application had led them to believe she was 22. While often appearing in short, tight garments, Armstrong, who went on to become a celebrated actor, did on one occasion break away from the standard weather script, when she informed viewers that “due to the drought, 1,000 head of cattle died. But don’t worry, beachgoers, it’s going to be another great day tomorrow with a top of 35 degrees”.

Decades later, the “weather girl” tag has proved hard to shake, as current Melbourne Channel Nine weather presenter Livinia Nixon told The Age in 2010. “TV and radio are very much boys’ clubs; they’re industries that are still very, very male-dominated,” she says, acknowledging that a male who presents the weather is a weather man, whereas she is a “weather girl”. “I wonder at what point you lose the ‘girl’?” she asks, having presented the segment on Nine’s 6pm weeknight news since 2004. “What age do you have to reach to not be called a girl any more?”

What if the woman presenting the weather has a relevant tertiary qualification? Back at Seven in Melbourne, Giaan Rooney remained in the role of weather presenter until taking maternity leave, when she was replaced by model and television personality Jo Silvagni, who was in turn replaced in late 2014 by Jane Bunn – who, as it happens, is also a qualified meteorologist. Her appointment also attracted media attention. When Nixon was asked about her new on-air rival, she told the Herald Sun that she didn’t think this would lend Seven’s bulletin any more clout. “I think it’s fantastic that Jane’s a meteorologist – hats off to her for doing the hard yards – but I’m confident working in conjunction with the Bureau (of Meteorology),” she says. “I feel very confident relaying all the information we get from them. Their accuracy rate has gone up over the years.”

Did Nixon, who had replaced the veteran weather presenter Rob Gell on Nine in 2010, have a point? A trained meteorologist of either gender might make the weather segment seem more credible to some, but would they enhance the substantive quality of information that is delivered? Historically the Bureau has insisted that provision of its information comes with a requirement that the media doesn’t mess with the message. TV stations can and do use the services of private weather companies to provide graphics, but the actual forecasts are still meant to be broadly consistent with the Bureau’s. So whichever nightly news channel you watch, won’t the next-day forecast be essentially the same?

With this and others questions in mind, I went to Melbourne’s Seven studios in Docklands to meet Bunn. After completing a Bachelor of Science at Monash University and a Graduate Diploma in Meteorology, Bunn worked for the Bureau in Sydney before turning to presenting the weather on television. “I loved the forecasting part of it but hated it when the message was being changed in the media by people who got their terms muddled, so I decided I wanted to present it,” she tells me, citing an incident where a forecast of “fine and mostly sunny” was abbreviated to “mostly fine”. “You can have trust in what we are saying because that message might be jumbled up elsewhere. You’re better off getting your weather from a meteorologist than a presenter because you know it’s as good as it can be.”

But Bunn doesn’t simply recite the Bureau’s forecast. Before her main segment goes to air at 6.55pm she checks the forecast models from Europe and Australia, which are updated after the Bureau releases its late afternoon forecast, to see if there are developments that might require some additional interpretation. She also analyses those same models to take the Bureau’s seven-day forecast one step further, providing viewers with an eight-day outlook.

For all her specialist knowledge, however, Bunn’s appearance has also been a talking point both in social media and in the gossip columns. “Jane Bunn had the farm boys panting when she was the weather girl on regional television,” began one Herald Sun story, before conceding that “she doesn’t fit the weather girl stereotype”. Bunn accepts that her image is to some extent constructed by others. When I bring up the subject of how she is characterised in social media, she points out that other people have considerable input into how she appears before the camera. “I’ve purposely made it so hair and make-up and wardrobe decide what I actually look like – and that allows me to concentrate on my craft which is forecasting.”

As well as presenting all the usual weather details, Bunn has the scope to discuss seasonal forecasts and weather news in her segment, which provides her with the opportunity to embed her meteorological knowledge in her reports. Despite such individual touches, however, weather presenters in Australia, including Bunn, stick far more closely to the official forecasts than their American counterparts. In the United States, it is commonplace for local TV stations to hire meteorologists to present the weather, and many of these develop their own forecasts, which may be based on National Weather Service (NWS) data, or on those of other private providers whose predictions may also differ from those of the NWS. And television has long been a much more popular source of weather forecasts than the NWS. A 2006 survey of more than 1,400 Americans found that 72% of them caught a local TV forecast at least once per day, but less than 20% obtained daily forecasts from NWS websites, with just 4% tuning in to National Oceanic and Atmospheric Administration (NOAA) Weather Radio each day.

It might be just as well that Australia has not gone down this track. As American data journalist Nate Silver has noted in the American context, “the further you get from the government’s original data, and the more consumer facing the forecasts, the less reliable they become. Forecasts ‘add value’ by subtracting accuracy.” This is particularly the case with precipitation predictions. Non-National Weather Service forecasters, it turns out, tend to overestimate the probability of rain. There is a logic of sorts to this “wet bias”, says Silver. “People don’t mind when a forecaster predicts rain and it turns out to be a nice day. But if it rains when it isn’t supposed to, they curse the weatherman for ruining their picnic.”

The wider effects of ending farm subsidies | Letters

The Guardian - Wed, 2017-08-02 04:23
Huw Jones charts the impact on farming of cuts in support and Michael McLoughlin looks at the causes of suicide among Indian farmers

Polly Toynbee (The Tories are split over farming. It’s hard not to gloat, 1 August) raises important issues. Subsidies were intended to lower food prices and increase discretionary income for manufactured products. The subsidy fills the gap between production costs and farm-gate prices, which were lowered by imports and by allowing food-chain “efficiencies” resulting in domination by the supermarkets. The inflexibility of EU-wide subsidies resulted a few years ago in tiny farm incomes, despite substantial investment in farms. This, combined with oppressive and chaotic management of subsidies by Defra, resulted in support for Brexit. Loss of subsidies will result in the closure of most affected farms that cannot subsidise themselves with non-farming income. Perhaps the price of rural holidays will have to increase.

You also report increased suicide rates amongst Indian farmers due to climate change (Farmers’ suicides linked to climate, 1 August), but suicides in response to agricultural depression are not uncommon in UK, either. Meanwhile, BNP Paribas is buying Strutt and Parker (Report, 1 August), famous for major land sales. French bankers clearly see a growing opportunity in selling distressed UK farms. Buyers will keep huge areas under common management, regardless of local land quality and ecosystems. Merged farms will need to use large suppliers, while smaller suppliers will go out of business. Small rural communities and dedicated local infrastructure will become unsustainable, reducing opportunities for tourism or even online businesses. Changes to subsidies will affect far more people than just farmers and will need to be considered very carefully.

A brief history of bearded cricketers | Letters

Energy prices | Moeen Ali | Prudish chemists | Gay chants | Liberalism

It is disappointing to see such a large price rise from British Gas (Report, 1 August), but let’s not slam these suppliers for being greedy. They’re inefficient and outmoded – and it’s customers who pay the price. Energy doesn’t have to be this expensive, as proven by the dozens of newer suppliers with lower costs and better service. The only way to fix the broken energy market and the stranglehold of the big six is with the urgent introduction of an energy price cap which will benefit all families.

• While you note that England cricketer Moeen Ali’s hat-trick to win the Oval Test broke several records (Sport, 1 August), you fail to mention an important one. He became the first England cricketer with a beard ever to take a Test hat-trick. The best that had been previously managed was a moustache, and that was Billy Bates in 1883.

Over 1,000 people killed in India as human and wildlife habitats collide

The Guardian - Wed, 2017-08-02 00:02

Elephant and tiger territories are shrinking as India’s growing population encroaches on wild spaces causing an increase in fatalities

A deadly conflict is under way between India’s growing population and its wildlife confined to ever-shrinking forests and grasslands. Data shows that about one person has been killed on average every day for the past three years by roaming tigers or rampaging elephants.

Statistics released this week by India’s environment ministry reveal that 1,144 people were killed between April 2014 and May 2017. That figure breaks down to 426 human deaths in 2014-15, and 446 the following year. The ministry released only a partial count for 2016-17, with 259 people killed by elephants up to February of this year, and 27 killed by tigers through May.

Utilities companies won't let you sell your own solar power. Why not?

The Guardian - Wed, 2017-08-02 00:00

The electric utility sector is broken – but the transformation we need will be virtually impossible so long as a handful of wealthy elites are calling the shots

A new report from the US-based Energy and Policy Institute last week found that investor-owned utilities have known about climate change for nearly 50 years – and done everything in their power to stop governments from doing anything about it.

From their commitment to toxic fuels to their corrosive influence on our democracy to their attempts to price-gouge ratepayers, it’s long past time to bring the reign of privately-owned electric utilities to an end.

Meat industry blamed for largest-ever 'dead zone' in Gulf of Mexico

The Guardian - Tue, 2017-08-01 21:19

A new report shows toxins from companies like Tyson Foods are pouring into waterways in the gulf and surrounds, causing marine life to leave or die

The global meat industry, already implicated in driving global warming and deforestation, has now been blamed for fueling what is expected to be the worst “dead zone” on record in the Gulf of Mexico.

Toxins from manure and fertiliser pouring into waterways are exacerbating huge, harmful algal blooms that create oxygen-deprived stretches of the gulf, the Great Lakes and Chesapeake Bay, according to a new report by Mighty, an environmental group chaired by former congressman Henry Waxman.

Underground magma triggered Earth’s worst mass extinction with greenhouse gases | Howard Lee

The Guardian - Tue, 2017-08-01 20:00

There are parallels between today’s and past greenhouse gas-driven climate changes

Coincidence doesn’t prove causality, as they say, but when the same two things happen together over and over again through the vast span of geological time, there must be a causal link. Of some 18 major and minor mass extinctions since the dawn of complex life, most happened at the same time as a rare, epic volcanic phenomenon called a Large Igneous Province (LIP). Many of those extinctions were also accompanied by abrupt climate warming, expansion of ocean dead zones and acidification, like today.

Earth’s most severe mass extinction, the “Great Dying,” began 251.94 million years ago at the end of the Permian period, with the loss of more than 90% of marine species. Precise rock dates published in 2014 and 2015 proved that the extinction coincided with the Siberian Traps LIP, an epic outpouring of lava and intrusions of underground magma covering an area of northern Asia the size of Europe.

The good news and bad news about the rare birds of Papua New Guinea

The Conversation - Tue, 2017-08-01 14:42

The rainforests of Papua New Guinea are home to one of the richest bird populations in the world. But many are threatened by logging and palm oil farming.

Now, a team of researchers led by Edith Cowan University have surveyed the PNG island of New Britain to see how the bird population is faring.

The good news: several bird species, like the Blue-eyed Cockatoo, were found to be doing better than before.

The bad news: the researchers saw only a few New Britain Kingfishers, and some vulnerable species, like the New Britain Bronzewing, Golden Masked-owl and Bismarck Thicketbird, were not seen at all.

Their results, recently published in the journal Bird Conservation International, help to inform the International Union for Conservation of Nature and Natural Resources (IUCN) Red List of Threatened Species.

Flowers work their healing magic on the old station platforms

The Guardian - Tue, 2017-08-01 14:30

Millers Dale, Derbyshire A galaxy of tiny purple globes sway where once the milk churns waited for the night train to London

The old railway station in this part of Derbyshire’s Wye valley presents an astonishing happenstance of mixed colour. There is the Van Gogh yellow of the ragwort and the dark mullein spikes. There are the blended lilacs of field scabious and the rose shades from wild marjoram and over most of the area towers a canopy of greater and black knapweed flowers creating a galaxy of tiny purple globes. In the wind, all these colours sway and mingle.

My favourite of all is in the blooms of the bloody cranesbill. It is intriguing that botanists used body parts to invoke its hue while the makers of matte lipstick call the same shade “pink peony”. Look closely at the petals and they comprise fields of exquisite magenta veined with red.
