Short-circuiting a superpower, city by city

The US is withdrawing from the Paris climate accord, but there are reassuring signs of action at a sub-nation scale.

At the opening of the Ecocity World Summit being held in Melbourne this week, I heard a lot about the many environmental initiatives my home city of Melbourne is taking. I was also pleased to hear the action being taken to address climate change at a regional level by the Government of my State, Victoria. These activities at city and state level made the lack of action being taken at the national level by my country, Australia, crystal clear.

The Hon Lily D’Ambrosio MP, Victorian Government Minister for Energy, Environment and Climate Change, told delegates that it is now law in Victoria to have zero net emissions by 2050. Her comments were followed by Melbourne’s Deputy Lord Mayor, Councillor Arron Wood, who told us that cities and states will do the heavy lifting to meet national greenhouse gas targets. And during the day’s conference presentations, the message was clear: the role of cities and sub-nation governments such as states has become increasingly important in the face of country-level inaction and scepticism about climate change.

During the Ecocity World Summit media conference (which had the media-friendly title of ‘Driving climate action in a Trump world – how cities can circumvent a superpower’), Kevin Austin, Deputy CEO of C40, told gathered media that cities are a cause of climate change due to dense populations and the large proportion of global emissions they cause, and hence also need to be part of the solution. C40 is a network of 91 of the world’s cities that have committed to urgent action on climate change.

‘All cities need to be carbon neutral by 2050 or earlier,’ he said. Referring to US President Trump’s statement, ‘I was elected to represent the citizens of Pittsburgh, not Paris’, Kevin said we need to abide by the Paris accord (to reduce global emissions to a level that would keep global warming to below 2 degrees Celsius), to do right by the citizens of both Pittsburgh and Paris, and the citizens of the world. ‘Cities can play a part on the national level, and also on the international level.’ (Pittsburgh’s Mayor, Bill Peduto, said that he was outraged at Trump’s statement, rejoindering that ‘It’s up to cities — not the federal government — to ensure carbon emission guidelines are being followed’.)

Aromar Revi, Director of the Indian Institute for Human Settlements, told the media that local governments are the most critical force to keep the world’s warming close to 2 degrees. He said that a territorial approach – that is, action by cities and states – is very important. ‘Australia is a world leader in adaptation, and has been for a long time,’ he said. ‘The world is likely to overshoot the 1.5 degree target, so we need to prepare for adaptation now because some of this stuff is unfortunately going to happen.’

As Ronan Dantec, Senator for the Loire-Atlantique Region in France, said, ‘Now we are in a time of action.’

Rent, don’t buy?

When I was young, my parents always told me that if I wanted to buy something, I should save my money and pay for it outright. ‘Buy, don’t rent’, was their recommendation for procuring everything from a TV set to a house. The logic in this advice was that rent, or its equivalent in ongoing payments, represents ‘dead’ money.

We all used to apply my parents’ logic to software. We’d fork out several hundred dollars for the latest version of Microsoft Office and spend ages feeding the multiple CDs that stored the program into our computers. Then, when it became too annoying dealing with Word 7 when you had only version 6, you would upgrade.

A few years ago, the software industry woke up to the wisdom of my mum and dad – if you are on the supply side, far better financially to get the punters to rent, not buy.

So, Microsoft quietly, but forcefully, pushed their millions of users to a ‘rent’ model. It’s just a couple of dollars a week, they said. You’ll always have the very latest software on your computers, they told us. Say goodbye to version incompatibility.

That’s all fine, but what if you simply want to write stuff and don’t need to be able to import, rotate and link a Pivot table from Excel into Word? I know there are plenty of free programs that will just let you type. But then there’s the challenge in reading other people’s work that they email you in packages like Microsoft Word, with all its associated design elements.

So, we’re back to renting.

Let’s do a quick stocktake of all the software that our company Scientell rents. There’s the Microsoft Office subscription at $10 per month. We pay $60 per month for our accounting software. Delivering our public webinars and teleconferences incur a $12.50 monthly charge. Our web site and email host charges $15. We pay Google $4.58 for hosting documents. Dropbox subscriptions fees of $10.75 a month let us share files.

Take a deep breath and add up those subscriptions: the business subscriptions are $112.83 per month, which is $1,354 each year.

It all quickly adds up. Do we really need all this software and data? Good question – and one that is worth asking regularly. I’ll add a reoccurring note to my calendar to do a stocktake. I just have to ensure that my monthly Internet bill gets paid so that I see it.



On dinosaurs, widows and badly named pubs

By Sarah Holper, guest blogger 

The first dinosaur fossil ever found was named ‘Scrotum humanum’, owing to its resemblance to a petrified scrotum. Some thought it was a Roman war elephant’s thigh, or that of a biblical giant. It was, in fact, a Megalosaur’s femur.

Some cultural relativism ought to be applied to this laughable blunder. Before dinosaurs were known to science, giants and dragons were the natural explanations for impossibly hefty unearthed bones. Presumably with much eye rolling, biologist Richard Owen suggested that these bones belonged to an extinct group of reptiles. He coined the name ‘dinosaur’ in 1841, Latinised from the Greek ‘deinos’ meaning ‘terrible’ and ‘saurus’ meaning ‘lizard’. Incidentally, the word ‘dire’ stems from the same terrible root.

On terrible roots, let’s exhume some dismaying English artefacts. According to 1500s mindsets, a woman after her husband’s death became a dusty fossilised relict. Alas, our word ‘relict’ is from the Latin ‘relicta’ meaning ‘widow’. Further abandonment-flavoured words like ‘relinquish’ and ‘derelict’ derive from the Latin verb form ‘relinquere’ – to leave behind. Before deserting this etymological tangent, a dip into maritime lingo. ‘Derelict’, now synonymous with a state of neglect, technically refers to cargo irretrievably sunk at sea. Accidentally lost but still floating cargo is flotsam (both ‘f’ words are from the Germanic ‘floter’, meaning ‘to float’). Jetsam is cargo deliberately thrown (‘jettisoned’, from the same Old French root ‘getaison’, meaning ‘a throwing’) overboard to stabilise a ship in crisis. Hence ‘flotsam and jetsam’ has become a phrase to describe miscellaneous worthless trash (much like a widow in the 16th century, apparently).

Far from flotsam and jetsam is fossilised tree resin. Not only can it fossilise other creatures in a gloopy tomb, it can form a fossil per se: amber. Amber has a curious quality of acquiring an electric charge when rubbed with certain materials. Some 1640s amber-rubbing escapades led polymath Sir Thomas Browne to dub this attractive property ‘electric’. The leap from ‘amber’ to ‘electric’? Our old friend Latin, in which amber is called ‘electrum’.

Finally, an alphabetical fossil. Old English was written in runes. Christian missionaries arriving in the 9th century soon imposed not only their religion on the Anglo-Saxons, but the Latin alphabet too. The rune ‘thorn’, pronounced ‘th’, looked most similar to the Latin ‘Y’. Thus ‘Y’ took thorn’s place as the ‘th’-sounding symbol, while thorn was jettisoned into an alphabetical mass grave.

It follows then that pseudo-historical venues named ‘Ye Olde’ so-and-so ought to be pronounced ‘the old’, not ‘ye old’. A world-view flipping bombshell, I know. Now you know how the benighted masses felt when their ‘dragons and giants’ turned out to be dinosaurs.

On erosion, explosions and gopher waffles

By Sarah Holper, guest blogger

Plurals need not end in ‘s’ as all schoolchildren with teeth (to cite two examples) know. What’s more, plenty of singular nouns are divisible: try replacing ‘freedom’ in the following quote by Ronald Reagan’s quote with ‘lemon tart’:

‘Freedom is indivisible – there is no “s” on the end of it. You can erode freedom, diminish it, but you cannot divide it and choose to keep “some freedoms” while giving up others.’

The sentiment behind Ronald Reagan’s speech perhaps excuses its non sequitur basis. Yet in an Administration where the Chief of Staff’s name – Donald Reagan – differed from the President’s by one letter, grammatical precision was surely more important than usual.

According to Reagan, freedom, like embankments, can be eroded. Erosion is the transportation of sand, soil or rock between locations due to surface processes. The Colorado River boasts the Grand Canyon for its eroding efforts. Bryce Canyon’s hoodoos wobble skywards thanks to wind stripping sandstone off a sturdy limestone skeleton. More abstractly, erosion can describe the undermining of any institution by insidious forces, such as the erosion of accurate grammar by politicians using flowery prose.

The Oxford English Dictionary cites a 1612 medical text as erosion’s debut: ‘This infirmitie proceedeth from gnawing and eroding humours’. It is unclear exactly what ‘infirmity’ is under discussion, though syphilis is always a safe bet for any historical deforming illness. ‘Erosion’ stems from the Latin ‘erodere’ meaning ‘to gnaw away, consume’. Divide the word further (a possibility, lo and behold, despite the word not ending in ‘s’) and the etymological roots are revealed: ‘ex-‘ means ‘away’; ‘rodere’ means ‘to gnaw’.

Rodents – gnawing mammals like mice and gophers with continuously growing teeth – are thusly dubbed from the same Latin origin. Gophers’ waffle-shaped burrows earned them their name from the French for waffle: ‘une gaufre’. Confusingly, the masculine form ‘un gaufre’ means ‘gopher’ in French. If ordering a gaufre fresh off the griddle iron, be sure to clarify with le garçon to avoid a disappointing meal of fried batter instead of juicy gopher meat. Or vice versa.

‘Ex-‘ as a suffix meaning ‘away’ or ‘out’ is rife in scientific parlance. Exothermic reactions are characterised by taking away heat. An exothermic reaction gone awry may involve an explosion – from the Latin ‘explaudere’ meaning to ‘drive off by clapping’. Rowdy Roman audiences would scornfully ‘out clap’ weak actors. Indeed, the actor would ‘go off with a bang’. From that Latin ‘plaudere’ we get our words ‘applaud’ and ‘plaudit’. A reasonable hypothesis may be considered ‘plausible’, literally meaning ‘acceptable, worthy of applause’.

Intensive agricultural practices have sparked an explosion of erosion. Over-grazed land stripped of soil-anchoring trees is a prime erosion target. Now exposed, quality topsoil is whisked away to leave salty, low-nutrient soil. Mulching, encouraging vegetation and reducing runoff with water tanks are all plausible solutions to combat erosion.

As a B-Grade actor in ‘King’s Row’, Reagan quipped: ‘Alright. I know. I’m always wrong. I always have been, ever since I can remember’. He may have been wrong about plurals, but he was right about the dangers of erosion.

Keeping it real and regional: communication to get Victoria climate-ready

This article first appeared in the December 2016 edition of Eingana, the journal of Environment Education Victoria.


How do you tell a Melbournian what their city’s climate will be like in the year 2070? You could explain that, if the world gets its act together and manages to lower its emissions of greenhouse gases, average temperature will rise by about 1.5°C. If emissions continue to be high, the temperature will rise by about 2.6°C.

Then you could say that extreme temperatures are likely to increase at a similar rate to average temperatures. Melbourne will endure more hot days, those hot days will become significantly hotter, and warm spells will last longer.

If their eyes are yet to glaze over, you could add that winter and spring rainfall are likely to be less than today, and that the frequency and intensity of extreme rainfall events will rise.

But how do you really convey what does all this mean? What will be the impact of this sort of temperature rise and rainfall reduction? There has to be an easier way of quickly communicating this complex, important information.

Thanks to CSIRO and the Bureau of Meteorology, there is. You can just say that in 2070, the climate of Melbourne will be more like the current climate of Adelaide. Most people know that Adelaide is hotter and drier than Melbourne, so they should immediately get a feel for what Melbourne’s climate will be like in future.

That city comparison comes from a communication tool called ‘climate analogues’. You will find it – and much, much more – on the Climate Change in Australia web site. The web site contains all the information underpinning the national climate projections released by the agencies in 2015.

The tool matches projected rainfall and maximum temperature with the current climate experienced in another location for 20-year periods centred on 2030, 2050 and 2090. You can find climate analogues for hundreds of Australian locations.

Regional climate change

The CSIRO and the Bureau of Meteorology projections are the most comprehensive ever prepared for Australia. However, their use at an intra-state/regional scale is limited.

The Victorian Government commissioned CSIRO to prepare regional climate projections for the state. The government were then faced with the challenge of conveying this information – so it informed people about their changing climate, explained the likely impacts of climate change, and described how best to adapt.

The Victorian Government contracted me and colleagues Karen Pearce from Bloom Communication and Rohan Hamden, a climate adaptation specialist, to prepare communication products that met this challenge.

The project represented the perfect opportunity to put into action some of the latest thinking and advice on communicating complex science.

The psychology of communication: Here and how; not gloom and doom

Decades ago, science agencies began employing information officers, communicators, public relations people and the like to pump out the facts. These staff wrote media releases, newspaper features, brochures, pamphlets and books describing scientific, technical and environmental findings.

The approach was based on the ‘empty bucket’ or ‘deficit’ model. It assumes that people have information gaps in their brains ready to be filled with facts, and that if a little fact pushing doesn’t work, then increasing the flow of brochures, newspaper articles, and radio talks will help.

The problem is that the deficit model has limited effectiveness. Often it fails completely, having the opposite effect of what was intended.

Climate change is an example of the failure of the deficit model. Despite massive communication efforts, a considerable proportion of people still do not accept that climate change is caused by human activities. A 2014 CSIRO survey (Leviston et al., 2015) found that 8 per cent of Australians don’t think that climate change is happening, 8 per cent have no idea whether it is happening or not, and 39 per cent of Australians say that it is happening, solely due to natural causes. Brulle et al. (2012) suggest that climate science has little direct influence on public opinion on climate change in the United States.

Propagation of more and more information is not the way to engage people with complex issues like climate change. Social scientists have long realised that inclusion and dialogue are essential.

Dr Sander van der Linden is a Social Psychology lecturer at Cambridge University. In a paper entitled ‘Improving public engagement with climate change: five “best practice” insights from psychological science’, (van der Linden et al., 2015), he provides recommendations on this topic. The five insights apply more widely than climate change.

Paraphrased, they are:

  • our brains value experience over analysis;
  • we are social and mimic peer behaviour;
  • the here and now is more important than something that may (or may not) affect us profoundly in future;
  • we like to win; and
  • human motivation is powerful.

Applying these insights to communication means that we should:

  • highlight personal experiences and local examples;
  • describe effective local action;
  • emphasise local changes;
  • accentuate the positive (for example, reducing emissions equals cleaner air); and
  • seek to build a better tomorrow.

So rather than ineffective messages of gloom and doom, the more effective communication approach relies on familiarity, hope and optimism

Climate-ready Victoria

The Victorian Government commissioned six brochures, covering each of the state’s regions, and an overall state-wide publication. The set, entitled Climate-ready Victoria carry the description: ‘Getting climate-ready involves understanding how climate change is likely to affect you and your region, and working out ways to adapt.’

We sought to develop content that:

  • has a clear, positive, empowering message/narrative;
  • provides a clear regional context in terms of climate, economic and demographic information;
  • highlights regional impacts of a changing climate; and
  • showcases real examples of climate-ready actions that are already under way.

We also catered for the many ways that people interpret information by incorporating:

  • clear, plain English and textual signposts;
  • pictograms and infographics to provide clear visual cues and summaries; and
  • different styles of graphs and tables to convey data.










Presenting technical information in a variety of ways can help people absorb information. The Victorian climate change brochures use a variety of graphics to convey information.


Throughout the process, the content development was refined by feedback from stakeholders and scientists to ensure that the information was accessible, useable and relevant to the particular region, but also that the underlying science was not lost in translation.

The brochures included the climate-related risks for primary production, infrastructure, tourism, health and the community, and the environment. They describe potential impacts on each sector and relevant adaptation measures.

Climate risks for primary production include lower rainfall, more heat days and increased fire weather. Potential impacts are likely to include earlier flowering times, changed distribution of pests and diseases and reduced water security. Adaptation measures could include considering enterprise diversification, different crop varieties and sowing times and regularly accessing long- and medium-range outlooks, as well as short range weather forecasts.

Supporting the brochures are regional data sheets for a range of climate variables, presented annually and by season.

‘The brochures present great information about climate change that is easy to read and understand. They help start the conversation about how the potential impacts of climate change could affect different industries and business, especially for understanding the potential risks and whether these should be considered in budgets. They also provide great references to where to get further information,’ said Sandi Bowles, Sustainability Programs Officer, Port Phillip Region, Department of Environment, Land, Water and Planning.

Ben Craven from Emergency Management Victoria, said ‘The brochures have been a valuable resource, combining all the relevant information into a single, easy to understand source. There’s the right amount of detail to bring people up to speed on the projected impacts of climate change. This information is useful in helping us understand Victoria’s needs for the future.’

Book review: ‘Surviving the 21st Century: Humanity’s Ten Great Challenges and How We Can Overcome Them’

Surviving the 21st Century Australia has no better science writer than Julian Cribb. He is knowledgeable, extraordinarily well informed and superbly adept at presenting accurate, fascinating information in a way that just begs to be read.

His latest book is Surviving the 21st Century: Humanity’s Ten Great Challenges and How We Can Overcome Them. The fact that we have survived for 16 years of the century shouldn’t lull us into thinking that the remaining 84 years will be straightforward. I write this review on the day WWF report that ‘worldwide populations of mammals, birds, fish, amphibians and reptiles have plunged by almost 60 per cent since 1970 as human activities overwhelm the environment’.

Each chapter in Surviving the 21st Century considers a great challenge, including mass extinction, resource depletion, weapons of mass destruction, climate change, universal toxicity, food crises, population and urban expansion, pandemic disease, dangerous new technologies, and self-delusion.

It’s easy to describe problems, more difficult to proffer solutions. Cribb does this at each chapter’s conclusion in a section called ‘What we must do’.

Surviving the 21st Century does something that few other publications do: it comprehensively addresses all the main threats to us and to our planet. The holistic approach offers more hope than efforts to tackle problems individually, which can sometimes make matters worse.

Cribb knows intuitively how to convey information vividly and accurately. Writing about frogs, he states, ‘Two in every five of their known species face extinction’. That expression grabs you more than the ’40 per cent’ that most scientists would write.

Years ago, US journalists coined the term ‘Hey Martha’ for stories and news items so amazing that when you hear them, you just have to shout across the room, Hey Martha, listen to this!’. Surviving the 21st Century is full of such examples. They grab your attention and make you think, which is the whole point. Hopefully, sufficient numbers of people thinking will lead to action.

Here’s a ‘Hey Martha’ from the book: What consumes 10 kg of topsoil, 800 litres of fresh water, 1.3 litres of diesel, a third of a gram of pesticide and causes 3.5 kg of carbon dioxide to enter the air? Answer: the last meal you ate. Now multiply that by all the meals you’ve consumed and all the people on Earth. No wonder we have a problem. As Cribb puts it, ‘the human jawbone is among the most destructive of implements on the planet’.

Here’s another sobering anecdote for Martha: ‘Tonight around two hundred thousand more people will sit down to dinner than dined last night.’

You’ll be hard pressed to find a page without a fascinating factoid. Cribb certainly does his research, and knows how to craft that research into unforgettable messages.

What’s his recipe for curbing the impact on planet Earth of our insatiable hunger? Sustainable urban food production using recycled water and organic waste; teaching the next generation to value and respect food; apply a food levy to pay farmers and indigenous peoples to restore and maintain the environment; introduce a ‘Year of Food’, teaching respect, awareness and appreciation of food, in every junior school on the planet. There are many more suggestions on the menu. Each is thought provoking and a number are completely original. It doesn’t matter if you disagree with some of the ideas or think that they may be unfeasible, Cribb has set out a range of options well worth considering. Doing nothing is not one of them.

If you’d like to pursue any of the idea and possible solutions, Surviving the 21st Century includes a detailed list of references.

The ‘sapiens’ in homo sapiens means ‘wise’ in Latin. We can demonstrate wisdom by getting hold of a copy of Surviving the 21st Century and applying some of the recommendations to our own lives. We can recommend the book to others. We can alert our leaders to the book and its contents. We owe this to ourselves and to our planet.



Learning from failure

As part of a major national project on innovation, Scientell has examined the contribution that learning from error and failure can make to innovation and progress. This is part of our work with the Australian Council of Learned Academies (ACOLA) to synthesise a wealth of information into a book on securing Australia’s future. The following is a sad example of failure.

On 29 March 2005, 37-year-old Elaine Bromiley entered a British hospital to undergo routine surgery to clear her sinuses. The mother of two was otherwise healthy.

Problems occurred immediately the anaesthetic was supplied. With no warning, Elaine’s oxygen levels plunged. Her airway was blocked – a most unusual event that happens in fewer than one in 50,000 routine cases of people being given an anaesthetic. The anaesthetist and the surgeon immediately tried to insert a tube into her airway. Additional medical staff quickly arrived to assist, including two recovery nurses, an ear, nose and throat surgeon and another consultant anaesthetist. For 20 minutes, the team desperately attempted to clear her airway.

Sadly, the emergency procedure failed. Elaine was transferred unconscious to the adjacent intensive care unit and died 13 days later.

Elaine’s husband Martin Bromiley was a commercial airline pilot. He knew how his industry would have responded to a similarly catastrophic event. One of the medical team told Martin that ‘maybe when this is investigated something can be learned. But we won’t investigate, not unless you sue or complain.’

‘For me as an airline pilot, that is where everything changed, because to me it is perfectly normal to investigate when something does not happen so you can learn from it, and here we had a situation where somebody was healthy, was going to be made more healthy, and was actually dead. I could not understand why you would not want to learn from it.’

It took some doing, but Martin managed to initiate an independent review of the case.

‘Arguably, it technically was a dream team to deal with this sort of emergency, but what we know happened, if you will excuse the phraseology, was that the situational awareness, the shared mental model of the three consultants, was different. They lost awareness of time; they lost awareness, perhaps more importantly, of the seriousness of the situation; they became fixated – which is not unusual under stress – on intubation to the exclusion of any other options, such as some form of surgical access.

From my background in aviation, I could see very quickly that these were in fact failings in what you refer to as “non-technical skills”: situation awareness, leadership, teamwork, prioritisation, communication, and assertiveness. These same human factors of failings in non-technical skills are the direct cause of 75% of aviation accidents.’

An incision into Elaine’s throat – a tracheotomy – may have saved her life. That it didn’t happen, was not the failings of any individual, but rather the failings of a flawed system.

Today, the findings from the inquest form the basis of training in Australia and elsewhere of healthcare clinicians, particularly those involved in advanced airway management.

The death of Elaine Bromiley was a tragic failure, but it was a failure that people learned from, and one that has improved the way in which emergency operating theatre procedures are conducted.


Is there a doctor on this flight?

Scientell is working with the Australian Council of Learned Academies (ACOLA) to synthesise a wealth of information into a book on securing Australia’s future. As part of this, we have examined the contribution that learning from error and failure can make to innovation and progress. This example demonstrates the way in which the medical profession is learning from the aviation industry’s approach to safety.

Safety is paramount for the aviation industry. Aircraft accidents are infrequent, but when they occur they involve massive losses of life. The exhaustive investigations that follow crashes have produced extensive literature into their causes, and new policies and regulations to improve safety. Research by the National Aeronautics and Space Administration (NASA) into aviation accidents has found that 70 per cent involve human error.

Writing in the British Medical Journal, Robert L Helmreich, professor of psychology at the University of Texas, states, ‘Error results from physiological and psychological limitations of humans. Causes of error include fatigue, workload, and fear as well as cognitive overload, poor interpersonal communications, imperfect information processing, and flawed decision making.’

‘In both aviation and medicine, teamwork is required, and team error can be defined as action or inaction leading to deviation from team or organisational intentions. Aviation increasingly uses error management strategies to improve safety. Error management is based on understanding the nature and extent of error, changing the conditions that induce error, determining behaviours that prevent or mitigate error, and training personnel in their use.’

Diagnosis should include data from confidential incident reporting systems and surveys, systematic observations of team performance, and details of adverse events and near misses.

It is now commonplace for medical doctors to learn from the approach to error and failure that has been refined and systematically adopted in aviation.

The error management approach that Helmreich advocates includes:

  • Dealing with latent factors that have been detected, changing the organisational and professional cultures, providing clear performance standards, and adopting a non-punitive approach to error (but not to violations of safety procedures);
  • Providing formal training in teamwork, the nature of error, and in limitations of human performance;
  • Providing feedback and reinforcement on both interpersonal and technical performance; and
  • Making error management an ongoing organisational commitment through recurrent training and data collection.

As physician Dr Lucian Leape, a physician and professor at Harvard School of Public Health, states:

‘The most fundamental change that will be needed if hospitals are to make meaningful progress in error reduction is a cultural one. Physicians and nurses need to accept the notion that error is an inevitable condition, even among the conscientious professionals with high standards. Errors must be accepted as evidence of system flaws not character flaws.’ [1]

10 tips for great public speaking

If I could just say a few words…I’d be a better public speaker.
Homer Simpson
Captivate, compel and communicate clearly next time you give a talk. Here are 10 tested steps to help you become a better presenter, and to truly do justice to your topic.

1. Know your audience. Do they have background information or are they lay people you’ll need to bring up to speed before you can explain your work? When presenting, one size certainly won’t fit all.

2. Write down three take home messages. These will dictate the path of your talk.

3. Power of voice rather than PowerPoint? Too often slides are simply speaker cue cards displayed to all. Consider standing out from the crowd by standing out from the crowd and speaking to them without the distraction of bullet points. Consider printing those bullet points on cards to keep you on course.

4. If tip 3 is too daunting, or if you have graphics and images essential to your talk, use PowerPoint or an equivalent. If you must use bullet points, employ a font size of at least 24 point. There are some helpful rules at rule is no more than 1 slide per minute.

5. Plan your talk. Use the dictum of ‘tell them what you are going to tell them, tell them, and then tell them what you have told them’. Repetition is good. Repetition is good.

6. Create your index cards or slides.

7. Shut your door, note the time, take a deep breath and practice your talk. Actually practicing the talk like this is the best way I know to increase polish and reduce nerves. On the day, you’re likely to speak for longer than during your practice session. Double-practice your opening and closing statements.

8. Fine tune the presentation as necessary based on your practice.

9. On the day, arrive at the venue in plenty of time. Don’t forget your cue cards, USB stick or laptop.

10. Imagine yourself confidently striding to the lectern, facing the audience, pausing to make eye contact and then confidently starting. Now do it.
