SESSION REPORT: Science does sell

By Laura Garcia Oviedo

Convincing media editors to give more space to science stories is difficult but not impossible. That was the main idea expressed during this session.

Debora Smith, who works at the Sydney Morning Herald newspaper, said science writers must use many strategies to be sure that their science story gets into the newspapaper.

“You have to sell it well, and make it as simple and interesting as possible to common people without trivialazing the story”, said Smith.

And she added: “Journalists try every time to get to the page one. Some stories are so interesting that they cross the line and reach the page one without problems, but other stories don’t”.

A good strategy to convince editors that a story deserves a space, said Smith, is getting good photographs, and graphics.

Mariko Takahashi, science news editor of the Asahi Shimbun Japanese newspaper, pointed out that are basic elements in a newspaper story. For example, it must include a date, it must have a big influence on society, it must surprise people, it must be interesting and it must be easy to understand.

But science stories present some problems, said Takahashi. It is difficult to find an exact date of a scientific discovery. Although some news is sometimes surprising to scientists is not always surprising to people. And headlines don’t always contribute to a good understanding of the story.

To avoid these problems he advised: to use the date when a paper is published or a speech is delivered, to point out the impact on society and to implement a writing style that gives surprise to readers.

Toronto Star journalist, Peter Calamai, chaired this session. He concluded: “If editors are good journalists, and they have the same values as you as a journalist, they are going to be able to recognize a good story”.

SESSION REPORT: Leading edge technologies maximize coal efficiency

By Jia Hepeng

More efficient use of coal, using new technologies, provides cheaper energy and reduces carbon dioxide emissions, according to the panel discussion at this session.

Peter Cook, head of CO2 Cooperative Research Centre of Australia predicts that the world’s use of coal will continue to grow, to 10.5 billion tons in 2030, despite its dwindling share in the world energy market.

He said, “The future of coal depends on costs, capacity, cleaner technologies and the availability of new energy sources.”

Increased coal consumption is thought to be a major contributor to increased carbon dioxide — global warming. As Australia faces increasing pressure, internationally and domestically, to cut carbon emissions, the call to reduce coal consumption and production has been growing.

However, Cook notes, studies show that a 50 percent increase in coal burning efficiency delivers up to three percent reduction of carbon emission per unit of coal consumption. With more new technologies, which dramatically increase coal efficiency, coal can “continue to be a reliable, securable, sustainable and clean energy.”

Australia’s heavy reliance on coal is shared by other countries, particularly China.
Wang Yu, a Chinese energy journalist from Beijing-based China Daily, revealed that in 2006, China produced 2 billion tons of coal, with two thirds of this used for electricity generation. In the near future, it is unlikely to reduce the world’s economic powerhouse’s reliance on coal.

While welcoming researches on cleaner coal, Ian Lowe, president of the Australian Conservation Foundation, complained that too many resources have been given to the sector, while research and development funding for sustainable energy is too small.

Lowe refutes the saying that Australians rely on coal for their jobs, saying the renewable clean technologies, such as growing plant for biofuels, are more labour intensive and hence the shift from fossil fuels to renewable energies will not result in lost jobs.

SESSION REPORT: Is Australia running out of water?

By Imelda V. Abano

Water in Australia is emerging as a scarce commodity, fueled by population pressures, intensive irrigation and erratic weather patterns brought on by global warming.

Addressing science journalists at this session, climate change expert and author Tim Flannery said Australia’s drought was part of a global dry spell that threatened the planet’s future.

“While water shortage is a global phenomenon not just in Australia, the present drought had already put huge strain on river systems,” Flannery said adding that scientists have found a 10 to 15 percent decrease in rainfall over a 50 year period.

He warned that climate change will likely make things worse for water resource management in the Murray-Darling Basin. “The water that’s available for us to use is declining because of this warming trend.”

The Murray-Darling Basin is one of Australia’s foremost river systems responsible for irrigating the country’s crops. Australia is faced with water scarcity in the Murray-Darling Basin as a result of diverting large quantities of water for use in agriculture.

University of Adelaide Professor Mike Young said managing water supply is the biggest climate-change adaptation facing Australia.

“We need to build mechanisms that make people aware of the value of water and to cope with these changes,” Prof. Young said.

Prof. Young said there is an urgent need for “well-designed urban and rural water allocation: and trading systems that offer ways of ensuring that this system will be effective.

“We need to work-out with the government and talk to the community about this problem,” he said.

On the other hand, South Australia’s premier, Mike Rann said the issue of water has been paramount. He suggested a need to introduce legislation next year and adaptation with the prevailing issue of water in Australia.

“What we’re seeing with this drought is a frightening glimpse of the future with global warming,” Rann said.

SESSION REPORT: The Hobbit saga continues

by Piyaporn Wongruang

A new round of excavations in the so-called Hobbit cave will be resumed in the hope that it will end the lasting controversies in the human evolution scientist community.

Dr Chris Turney, a scientist from Australia’s University of Wollongong, said excavation will resume between June and July at the Indonesian cave where they originally found the remains of the new species of modern human Homo florensiensis, now dubbed the Hobbit because of its dwarf-like characteristics.

Dr Turney joined his colleague, Dr Richard Roberts, and the Sydney Morning Herald’s science editor Deborah Smith in this session, Uncovering the Hobbit

In 2003 the team first discovered the remains of skeletons and skulls, which were relatively contemporary — around 18,000 years old up to nearly 100,000 years — and relatively smaller, when compared to other designated remains including Homo erectus and Neanderthals.

The first set of remains was discovered in Liang Bua Cave on Flores Island of Indonesia. The team believed that it was a woman about a meter tall in height.

A few years later, the species drew much criticism, or verbal bombarding, from some scientists in the field, and even from those once worked on the same team. They claimed this species had some disorder that made their skull relatively small. Therefore it was not a new species. Dr. Turney is working on carbon dating these remains.

“It would be lovely to find another example. If there was another complete skeleton, it would help demonstrate that, yes, this is a new species,” said Dr Turney, acknowledging that such the skeleton was rare.

Depending on available funding, the team plans to go deeper into the back of the cave where they have already found piles of bones that have not yet been identified.

Collaborating researchers have also been working on different sites including the Western side of the island and Sulawesi.

Climate change and the spread of disease

SESSION REPORT: Climate change has far-reaching ramifications

by Piyaporn Wongruang

Former U.S. vice president Al Gore climbed over an elevator in one of the scenes featured in his recent Oscar Award documentary, “An Inconvenient Truth” to demonstrate how high the carbon dioxide greenhouse gas would rise in the sky, if the current emission course remained unchanged.

The elevator lifted him up to about three stories.

“An Inconvenient Truth” generated unprecedented discussion about climate issues worldwide. But some scientific reports about the subject are still very difficult to promote.

While people worldwide have been awed by the scenes of fierce storms, and such, the impact of climate change on people’s health apparently still lies in scientific reports, which are still in the hands of the scientists.

Dr. Tony McMichael, review editor for the Human Health chapter of the Intergovernmental Panel on Climate Change’s working group II said, the climate change focus is still very much on political and economic aspects.

“But we also know that public health is at risk,” he said.

An example of this was the heat waves in Europe during 2003, when death tolls increased to 900 when the temperature rose above the normal average daily temperature by about 12 degree Celsius.

Secondary impacts on people’s health, include increased injuries from extreme events, and the rise of infectious diseases and malnutrition, especially among the world’s
poor, Dr McMichael added.

Dr. Neville Nicholls, a lead author about climate change, said although reports could establish initial relationships between climate change and public
health, more knowledge is needed to help people better address these impacts and come up with adaptation measures.

He said people could start to act now. Take the case of Australia, which has attempted to mitigate impacts of heat-waves, which could become problematic to its senior citizens.

“We already know that people died because of them, and even though it may have not been from climate change, it’s still good to develop adaptation measures,” said Dr Nicholls, adding that adaptation could go in hand with mitigation.

Dr. Mongkol Na Songkla, Thailand’s Public Health Minister, said Thailand monitors the changing trends of some tropical diseases as a pro-active measure against climate change.

Recently, the ministry detected a surge in Malaria in the western part of the country, although its relation has not yet been linked to the change in weather patterns.

Apart from tropical diseases, Thais have also been encountering hotter and wetter weather, he said.

“The most significant thing for us to do is to equip our
people with adequate knowledge about climate change so that they can adapt themselves to the changing climate. Apart from this, our ministry will try to closely watch changes in disease trends, which may be related to the changing weather,” said Dr. Mongkol.

Health benefits will also help compensate the cost of mitigating climate change in the future.

Global concentration of greenhouse gases, mainly carbon dioxide, methane and nitrous oxide have increased markedly as a result of human activity since 1750, and now far exceed pre-industrial values.

The increase of carbon dioxide is due primarily to fossil fuel use and land use change, while that of methane is primarily due to agriculture.

These have caused the total global temperature to increase up to 0.76 Celcius.

Eastern parts of North and South American northern Europe and northern and central Asia during 1900 to 2005 observed increased precipitation, while the Sahel, the Mediterranean, southern Africa, and parts of southern Asia observed drying condition.

More intense and longer droughts have been observed over wider areas since 1970s, particularly in the tropics and subtropics.

Both past and future human carbon dioxide emissions will continue to contribute to warming and sea level rise for more than a millennium.

Science versus business — A clash of cultures

SESSION REPORT: Let the buyer beware, let the consumer be wary

By Catherine Beehag

The divide between reporting science and reporting about technology-based businesses, was the focus of the discussion forum chaired by Dr Allan Finkel entrepreuner and executive publisher of Luna media.

Panellists included Clive Cookson, science editor of the Financial Times; Rebecca Wilson, consultant to the private and public sector at Buchan Communications; David Blake, publisher of Bioshares (a weekly biotech stock report); and Simon Grose, freelance writer/editor for the S&T and ICT sectors.

Science-based business, particularly private and public biotech companies, often produce media releases in quantity rather than quality, says Cookson. Journalists at this discussion raised the point that reporting within tight deadlines and embargos makes it difficult to fully investigate the credibility of company claims, risking public embarrassment and story inaccuracies.

Cookson said it’s important to put the science in media releases into context and to put a dollar figure on the updates.

Journalists must “explain the science and not mislead the public” Wilson said.

Blake claimed he loved how electronic media has opened pathways and communication avenues meaning journalists are “no longer restrained by one source.” This improves credibility to those who use it. He also mentioned that Australians love magazines and there are plenty out there which cover everyone’s interests.

Grose highlighted the need for journalists to check on what is produced in media releases. For example, he warned against reporting on living cell technologies when the technology was not ready to be used on human trials.

He said the proverb, “Let the buyer beware, let the consumer be wary” should still be used.

SESSION REPORT: Burn, baby, burn

By Brendan Borrell

As that 40-foot wall of fire closes in on your uninsured home, it’s important to remind yourself that wildfires have been humanity’s erstwhile companion on the ecological landscape for thousands of years.

In this session, a panel of scientists outlined some of the benefits of that friendship and strategies for living with fire in the 21st century.

“Bushfires are not necessarily ecological disasters,” said Ross Bradstock of University of Wollongong, “In fact fires in these environments may be determinants of diversity.”

Aboriginal peoples, for instance, have long used fires to clear choking vegetation from savannahs and wetlands, which increases plant diversity and, consequently, populations of game animals. Sadly, much of that traditional knowledge has been forgotten, but Peter Christophersen of CSIRO Sustainable Ecosystems related his work restoring such practices to aboriginal communities in and around Kakadu National Park.

Dick Williams, also at CSIRO Sustainable Ecosystems, further discussed the role of traditional knowledge in a prescribed burn program in Northern Australia. Bushfires account for half of Australia’s greenhouse gas emissions and as the climate grows hotter and drier, finding ways to manage — though not extinguish — natural wildfires is going to be more crucial.

In spite of these benefits, suburban dwellers may still be leery of welcoming wildfire into their neighborhoods. But John Schauble of the Country Fire Authority dispelled some myths about wildfire, including that nightmarish image of a wall of flame inching up on our homes.

Ninety percent of homes catch fire due to ember attack, he said and the “chance of being killed by bushfires is statistically very slight.” What this means is that in most cases, it is quite easy to stay and defend your home from fire provided you’ve had some basic training. He added the most dangerous thing you can do is evacuate at the last minute.

Whether we like it or not, fires are here to stay, the scientists agreed. Let’s try and make friends.

SESSION REPORT: Now is not the time for complanency

By Julia Hind

Our planet is changing, a leading Arctic scientist warned this week.

Speaking at the Wednesday morning session, Louis Fortier, Professor at the Université Laval in Canada, called for governments to have the political will to cut carbon dioxide emissions.

“If we don’t do anything now, this trend could be catastrophic,” he said.

Professor Fortier described some of the changes already observed in the Arctic including the reduction of summer ice cover. He said there has been a 30 per cent drop in summer Arctic ice cover in the past 30 years, with the greatest changes observed since the 1990s. He added that the evidence suggests the rate of melt was accelerating.

“Things are changing. There is an assault on the ice from the atmosphere but also from an increase influx of water from the Atlantic Ocean into the Arctic Ocean”. He believes predictions that the Arctic could be free of ice in the summer by 2015 were a possibility. This in turn, he said, would have enormous effects on animals and people, as well as raising major geopolitical questions.

But it is not just in the Arctic where the effects of climate change are becoming apparent. The meeting also heard from Stephen Rintoul, a scientist with CSIRO Marine and Atmospheric Research, who described the crucial role played by the Southern Ocean in transporting heat around the globe and in absorbing carbon dioxide.

He said studies show the Southern Ocean is also changing with water at the bottom less saline and less dense than 30 years ago. This change in salinity and density could affect the water’s ability to sink and subsequently slow the ocean circulation.

The recently launched International Polar Year will give scientists an opportunity to study the Southern Ocean in a way they have not before. Scientists from 18 nations are taking part in a project to observe the ocean simultaneously from different locations, as well as in the winter and from under the ice.

SESSION REPORT: Climate Change in Ocean and how the media balance the reporting

By Xuxiuhua (from www.people.com.cn,China)

Climate change is now a hot topic to governments and scientists in developed and developing countries.

But it seems we pay too much attention to the land and not enough attention to the ocean.

At this session, Steve Rintoul, a scientist from CSIRO Marine & Southern Ocean Studies, says that since 1955, 84 percent of “global warming” is found in the ocean. So it stands to reason that the ocean, especially the ocean in polar regions, plays a critical role in climate change.

Polar regions can regulate the amount of CO2 — the main greenhouse gas which can cause global warming — being absorbed by the oceans. And new evidence shows that ice sheets are more dynamic than we thought before. Analysis of satellite data and tide-gauge observation indicates that the rate of sea-level rise has been increasing.

However there is another opinion. Some scientists consider that if you study the history of climate change criteria, the climate change we are enduring now is normal. The question is should the media present both sides of the argument to the public?

2nd SESSION REPORT: REPORTING CLIMATE CHANGE: THE DEVELOPING WORLD PERSPECTIVE

Presentation by Ochieng’ Ogodo

No doubt, communities need information on climate change. Good reporting on climate change is becoming increasingly important, especially for the developing world that has fragile economies and the vulnerable poor.

More and more, our lives are getting affected by the ever changing and unpredictable weather conditions. The developing world need to think about climate change, consider its impact on the environment, and deal with the problem. The community needs well informed science journalists who can report accurately and impartially on the impact of science on the society and across the world yet the subject is hardly covered by media in the South.

Throughout the 1990s, the media in the developing world was at the forefront of reporting on the devastation brought by the ‘El Niño’ rains, and bringing the issue of global climate change - and its impact on the local economy - into sharp focus.

The extensive coverage provided farmers and rural communities with a scientific explanation for the dramatic weather changes that they had been witnessing in recent years.

But while such high-profile occurrences captured the public imagination and generated intense debates on the impacts of environmental degradation on people’s day-to-day lives, the momentum generated was not sustained.

The topic of climate change that has captured the attention of the world for almost a decade 2000s, especially the developed nations, though they are culpable as major contributors to global warming, is not getting adequate attention in the media in the south.

The media has continued to focus on the ‘big’ stories such as deaths from drought, or the destruction caused by floods, with little information being provided on how to cope with the effects of climate-related changes.

Climate change is a relatively new concept within African media. Few journalists - or even editors, who are the gatekeepers of stories that go on air or into print - have a clear grasp of the science behind this phenomenon. On many occasions, science-oriented stories, as well as those covering forestry, agriculture, and climate change, get ‘spiked’. Publishers prefer stories about crime, violence and political scandal because this is what ‘sells.’

Yet above all, what farmers and rural communities require for mitigating and adapting to the effects of climate change, is access to information.

Farmers need to know whether the changing circumstances in which they grow their plants or raise their animals is merely a question of variability or a permanent change to weather patterns. Communities across the south also need channels through which they can share information on strategies that have worked well for them, and to adapt such techniques to their own circumstances, whenever possible.

Beyond sharing practical experiences, civil society organizations in the South need to discuss how best to exploit international support available through such instruments as the Kyoto Protocol’s Clean Development Mechanism (CDM), while continuing to debate amongst ourselves whether these approaches to emissions reductions are in their best interest.

The media - television, radio, print and online - naturally have a vital role to play in such debates, and yet there is a dearth of coverage of science issues in the developing world. A recent survey by the London-based NGO, Panos, of 47 journalists and from Jamaica, Zambia, Honduras and Sri Lanka found considerable frustration amongst media professionals, with what they felt was a severe lack of interest by editors.

Media owners are often concerned about short-term profits and may be unwilling to criticize industry, or offend advertisers. As many of the media houses operate on shoestring budgets, they often do not have adequate resources to undertake thorough investigation of climate-related stories.

Illiteracy too can be an obstacle to awareness, although the creation of online image banks of photographs and diagrams could help to convey the impacts of various facets of science.

There is also a need to build bridges between scientists and journalists. Scientists are often unwilling to simplify their research findings for a lay audience, so journalists have to sharpen their skills to simplify jargon heavy scientific content and make the subject more relevant and easier to understand.

We journalists too can do much to help ourselves. We can set up networks in order to share information. The Caribbean Environmental Reporters Network (CERN) and the Kenya Environment and Science Journalists Association (KENSJA) are good examples.

We also need to build bridges between the developed and developing environmental and science journalists so that we can exchange ideas and information.

Lack of pulling together-everyone with a stake in this problem - journalists, editors and publishers, NGOs, policy makers and funders, and of course the people of the developing world – are not pulling together to fill this grievous information gap. We need to do that.

SESSION REPORT: Take your head out of the sand

By John Bohannon

“How much time do we have left?” This was one of the hard questions asked at this session. John Veron, coral reef scientist replied: “I’d say we have 10 years at most.” in which we must curb greenhouse emissions to avert disaster.

Although the Great Barrier Reef, the world’s largest biological structure, is in remarkably good shape, compared with other reefs around the world, action is required now.

Veron stressed that the key issue for coral reefs will be ocean acidification. As atmospheric carbon dioxide concentration rises, the pH of the ocean drops. Low pH makes it difficult for corals to build their limestone skeletons. This will make coral reefs fragile so that they would crumble in heavy seas and severe storms. Such reefs would no longer provide habitat for the myriads of animals that depend on them including fish, and lead to mass extinctions.

The amount of carbon dioxide already in the atmosphere due to human activities may be “committing the earth to destruction,” said Veron.

Daniel Gschwind from the Queensland Tourism Industry Council says that tourism operators are working to be part of the solution. The tourism industry is taking part in discussions and fostering stewardship of the reef.

The tourism industry in Australia is worth about $5 billion per year, and employs about 50,000 people —leaving aside the vital ecosystem services it provides.

Paul Marshall, from the Great Barrier Reef Marine Park Authority, urged that “rather than reaching for the bottle of valium,” we must take the practical steps that are possible right now. Even if climate change cannot be averted, the “resilience” of the reef can be bolstered by removing stresses such as pollution and overfishing. The Great Barrier Reef Marine Park was recently re-zoned using the best science possible, which increased protected (or ‘no-take’) areas from less than 5% to about 33%. This is also helping to build the Reef’s resilience.

Doing so is a moral imperative, said Marshall, because taking action now can mean the difference between complete disaster and a slow but steady recovery in the coming centuries.
