It’s no secret that mining is important to Australia, but that doesn’t necessarily make it popular with society at large.
We wanted to have a better understanding of what Australians think about mining, so in 2013/14 we conducted an online survey of 5,121 Australians.
The survey results have now been published as Australian attitudes toward mining: Citizen Survey – 2014 Results
Surveying community attitudes helps us to understand the impacts and benefits of mining, and how the relationship between the mining industry, government and society affects what Australia’s citizens think about it, and how much they accept the mining industry. It gives us insight into what needs to happen before mining has a ‘social licence to operate’ in Australia.
We’ve gone beyond basic descriptions of attitudes towards the extractive industries, and looked at the relationship between mining and society in a more constructive and sophisticated way.
We wanted to know what goes into influencing trust in the mining industries, and the government, over mining developments. What, for example, is the relationship between good governance and social acceptance of the extractive industries? What are the key issues for a productive dialogue between the extractive industries and other stakeholders?
Some of the important findings from the survey are that:
- People view mining as central and significant to Australia’s economy and standard of living. They see it as a ‘necessary’ industry for Australia, which is important to Australia’s future prosperity
- Australians generally understand what it means to have a significant mining industry. Overall, they think that at present the benefits of mining outweigh its impacts.
- The more the benefits of mining outweigh the costs, the higher the level of acceptance. If this balance is perceived to move toward the negative impacts of mining, acceptance of mining will be eroded.
- Australians trust and accept the industry more when they believe the industry is listening to them and will respond to their concerns, when benefits from mining are shared equitably, and when the legislative and regulatory frameworks in place make them confident that industry will do the right thing.
- Governments and industry need to work with communities to earn and maintain the ‘social licence to operate’ and develop effective, constructive, mutually beneficial relationships.
As heads of state gather in New York for tomorrow’s United Nations climate summit, a new report on the state of the world’s carbon budget tells them that greenhouse emissions hit a new record last year, and are still growing.
It shows that global emissions from burning fossil fuels and cement production reached a new record of 36 billion tonnes of CO2 in 2013, and are predicted to grow by a further 2.5% in 2014, bringing the total CO2 emissions from all sources to more than 40 billion tonnes. This is about 65% more fossil-fuel emission than in 1990, when international negotiations to reduce emissions to address climate change began.
Meanwhile, deforestation now accounts for just 8% of total emissions, a fraction that has been declining for several decades.
The growth of global emissions since 2009 has been slower than in the prior period of 2000-08. However, projections based on forecast growth in global gross domestic product (GDP) and continuance of improving trends in carbon intensity (emissions per unit of GDP) suggest a continuation of rapid emissions growth over the coming five years.
Global emissions continue to track the most carbon-intensive range among more than a thousand scenarios developed by the Intergovernmental Panel on Climate Change (IPCC). If continued, this situation would lead to global average temperatures between 3.2C and 5.4C above pre-industrial levels by 2100.
There have been other striking changes in emissions profiles since climate negotiations began. In 1990, about two-thirds of CO2 emissions came from developed countries including the United States, Japan, Russia and the European Union (EU) nations. Today, only one-third of world emissions are from these countries; the rest come from the emerging economies and less-developed countries that account for 80% of the global population, suggesting a large potential further emissions growth.
Continuation of current trends over the next five years alone will lead to a new world order on greenhouse gas emissions, with China emitting as much as the United States, Europe and India together.
Country emission profiles
There are several ways to explore countries’ respective contributions to climate change. These include current emissions, per capita emissions, and cumulative emissions since the industrial revolution.
The largest emitters in 2013 were China, the United States, the 28 EU countries (considered as a single bloc), and India. Together, they account for 58% of global emissions and 80% of the emissions growth in 2013 (with the majority the growth coming from China, whereas the EU cut its emissions overall).
Here’s how the major emitters fared in 2013.
Emissions grew at 4.2%, the lowest level since the 2008 global financial crisis, because of weaker economic growth and improvements in the carbon intensity of the economy. Per capita emissions in China (7.2 tonnes of CO2 per person) overtook those in Europe (6.8 tonnes per person).
A large part of China’s high per capita emissions is due to industries that provide services and products to the developed world, not for China’s domestic use. China’s cumulative emissions are still only 11% of the total since pre-industrial times.
Emissions increased by 2.9% because of a rebound in coal consumption, reversing a declining trend in emissions since 2008. Emissions are projected to remain steady until 2019 in the absence of more stringent climate policies, with improvements in the energy and carbon intensity of the economy being offset by growth in GDP and population. The United States remains the biggest contributor of cumulative emissions with 26% of the total.
Emissions fell by 1.8% on the back of a weak economy, although reductions in some countries were offset by a return to coal led by Poland, Germany and Finland. However, the long-term decrease in EU emissions does not factor in the emissions linked to imported goods and services. When accounting for these “consumption” emissions, EU emissions have merely stabilised, rather than decreased.
Emissions grew by 5.1%, driven by robust economic growth and an increase in the carbon intensity of the economy. Per capita emissions were still well below the global average, at 1.9 tonnes of CO2 per person, although India’s total emissions are projected to overtake those in the EU by 2019 (albeit for a population nearly three times as large). Cumulative emissions account for only 3% of the total.
Emissions from fossil fuels declined in 2013, largely driven by a 5% decline of emissions in the electricity sector over the previous year (as shown by the Australian National Greenhouse Gas Accounts). Fossil fuel emissions per person remain high at 14.6 tonnes of CO2.
Is it too late to tame the climate?
Despite this apparently imminent event, economic models can still come up with scenarios in which global warming is kept within 2C by 2100, while both population and per capita wealth continue to grow. Are these models playing tricks on us?
Most models invoke two things that will be crucial to stabilising the climate at safer levels. The first is immediate global action to develop carbon markets, with prices rapidly growing to over US$100 per tonne of CO2.
The second is the deployment of “negative emissions” technologies during the second half of this century, which will be needed to mop up the overshoot of emissions between now and mid-century. This will involve removing CO2 from the atmosphere and storing it in safe places such as saline aquifers.
These technologies are largely unavailable at present. The most likely candidate is the production of bioenergy with carbon capture and storage, a combination of existing technologies with high costs and with environmental and socio-economic implications that are untested at the required scales.
There are no easy pathways to climate stabilization, and certainly no magic bullets. It is still open to us to choose whether we halt our CO2 emissions completely this century – as required for a safe, stable climate – or try instead to adapt to significantly greater impacts of climate change.
What we have no choice about is the fact that the longer emissions continue to grow at rates of 2% per year or more, the harder it will be to tame our climate.

The winners of the 2014 IgNobel prizes have just been announced, and there’s an Australian among them. Peter K. Jonason from the University of Western Sydney shared the IgNobel for Psychology with Amy Jones and Minna Lyons, for providing evidence that people who habitually stay up late are, on average, more self-admiring, more manipulative, and more psychopathic than people who habitually arise early in the morning.
We are filled with admiration.
CSIRO wasn’t among the winners this year, but we’re going to take the opportunity to boast about our earlier winners.
In 2011, David Rentz (formerly of CSIRO) and Darryl Gwynne shared the IgNobel Prize for biology, for their groundbreaking discovery that a certain kind of Australian beetle attempts to mate with stubby bottles. Specifically, that male Buprestid beetles (jewel beetles or metallic wood-boring beetles) had a particular attraction to brown stubbies – none of this fancy craft beer in clear glass for them. In true scientific spirit, having noticed this occurring, they took steps to confirm the mating hypothesis. They ruled out the beetles being attracted by beer residue – the stubby bottles were completely dry. Nor were the beetles interested in a discarded wine bottle nearby – suggesting the colour of the bottle was the source of the attraction.
They then placed several more stubby bottles within range of the male beetles, and found that these too were extremely appealing to the beetles. So appealing, in fact, that they didn’t give up of their own accord, but had to be physically dislodged from making their amorous advances.
This, of course, provides a valuable lesson about the unintended consequences of littering. Throwing away a stubby can cause grave disappointment for beetles.
But these are not our only IgNobelists.
In 2006, Nic Svenson and Piers Barnes took out the IgNobel in mathematics for working out the solution to a problem that has confounded photographers for many years: how many photos do you need to take to be sure no-one is blinking.
They managed to reduce it to a (fairly) simple rule of thumb. For groups of less than 20 people, take the number of people in the group and divide that number by three. If you take that number of photos you can be virtually certain one of them will be blink-free. If the light is bad, divide the number of people in the group by two, because there’s a greater chance people will be blinking whilst the shutter is open.
This doesn’t work as well when the groups get larger: the number of photos grows so large that the group is likely to lose patience. But as they point out, the more people in a photo, the less it matters if one of them is blinking. And you’ll be pleased to know this was all experimentally tested in the canteen at lunchtime.
So congratulations to this year’s winners, commiserations to the losers, and onwards and upwards for the spirit of inquiry that drives improbable research.
Next year, next year …
Residents in Queensland’s Western Downs region have mixed feelings towards coal seam gas (CSG) development taking place in their midst, according to our CSIRO survey.
More than two-thirds of locals described themselves as “tolerating” or “accepting” CSG, while only 22% had openly positive attitudes. However, just 9% of survey respondents rejected the industry outright.
Around half of the surveyed residents felt that their community was struggling to adapt to changes. Residents were also less optimistic about the future, with many predicting a decline in community wellbeing over the coming years.
Attitudes to coal seam gas
We conducted a representative survey of 400 people living in and around the towns of Chinchilla, Dalby, Miles and Tara, all of which are experiencing varying stages of CSG development. We asked people about their attitudes to CSG, as well as their opinions on the wellbeing and resilience of their communities in the face of both opportunities and challenges associated with rapid CSG development.
Opportunities include increased employment and business, new services and new facilities, and a more vibrant community, whereas the challenges include water and land management, traffic conditions and safety, and affordable housing.
There were mixed feelings towards CSG development in the region, with almost 70% saying they either “tolerate” or “accept” it. A minority (22%) “approve” or “embrace” it, while a smaller minority (9%) of respondents “reject” it.
Although these results indicate that attitudes to CSG are not strongly polarised in these communities, it is clear that some community members are strongly opposed to it.
In response to questions around how residents felt their community was dealing with CSG development in their region, about 50% felt that their community was struggling to adapt to the changes – either “resisting”, “not coping”, or “only just coping” with CSG development.
Other results show that more positive attitudes to CSG are associated with community perceptions of being resilient, the environment being managed well for the future, good employment and business opportunities, and resource companies, government, and business working effectively with residents to deal with changes.
Differences across the region
Residents in Chinchilla see their community as adapting to changes more effectively than people in the other areas we surveyed. This reflects a perception that Chinchilla has better employment and business opportunities than places like Dalby and Tara, where respondents were more likely to find these opportunities unsatisfactory.
People who lived out of town reported lower levels of social interaction, services and facilities, employment and business opportunities, and overall community wellbeing than town residents. Although this may reflect general differences between rural and town life, those living out of town also had less favourable attitudes toward CSG (see the second chart above) and lower expectations of future community wellbeing .
Nevertheless, the overall average of community wellbeing across our whole survey was rated at 3.8 out of 5, which is robust and higher than many other Queensland regions when compared to similar items surveyed in a previous study.
Improving the situation
Our survey offers a snapshot of how people in Queensland’s Western Downs are feeling about the changes happening to their communities, and could form a basis for future strategies to support them.
The results suggest that investments made in wellbeing and resilience could lead to a more optimistic outlook for the future. In particular, three key areas that cause community dissatisfaction are road infrastructure, community participation in decision-making, and long-term environmental management.
However, we also found that while improving these things would benefit communities, these are not the most important factors for overall wellbeing. The things rated as most important are: services and facilities, community spirit and cohesion, a socially interactive community, personal safety, and environmental quality.
More optimistic outlooks for community wellbeing are associated with community resilience; especially good working relationships between groups, planning and leadership, supporting volunteers, and having access to information. Targeted investments are important but need to be combined with good collaboration between state and local governments, CSG companies, and local communities to enhance future community wellbeing.
Given that Queensland is more advanced than any other state in terms of CSG production, our study might also offer lessons for other regions of Australia that are facing the issue of CSG development, either now or in the future.

Australia’s Biodiversity series – Part 10: Inland waters
Even though it is one of the world’s most arid continents, Australia’s inland waters support a rich diversity of life.
Rivers, streams, wetlands, floodplains, lakes, underground aquifers—we’ve got them all and they all support native species.
Biodiversity is enhanced by the wide variation in rainfall across the continent and the change in climate from the tropical north to the temperate southern regions. Life in Australia’s inland water ecosystems has had to adapt to the ‘boom and bust’ that comes from periods of both extreme dry and extreme wet.
Human development has had a dramatic impact on these ecosystems, particularly in the Murray Darling Basin and other areas in the southeast, as we use water for our cities and towns and for irrigated agriculture. These water uses are obviously of great benefit to the Australian population but the use of the water and the infrastructure associated with it can disrupt the natural flows of water and nutrients through inland water ecosystems, which native plants and animals depend on.
In the tenth video of our Australia’s Biodiversity series, Dr Carmel Pollino talks about Australia’s unique inland water ecosystems and how water can best be managed for the benefit of biodiversity and our communities:

Mycologists – scientists who study fungi – estimate there are up to five million species of fungi on Earth. Of these, only about 2%, or 100,000 species, have been formally described. So where are the other 98% of fungi hiding?
At least three, it seems, were hiding in a supermarket packet of dried porcini mushrooms from China. Mycologists Bryn Dentinger and Laura Suz from the Royal Botanic Gardens in Kew, UK, used DNA sequencing to identify three new species in a packet of dried porcini mushrooms purchased from a supermarket, and report their findings in the journal PeerJ today.
The internal transcribed spacer (ITS) is a DNA region commonly used to identify fungi. (In fact, it’s been called the “universal DNA barcode marker for fungi”.) In their PeerJ paper, Dentinger and Suz compared previously published ITS sequences for porcini and discovered significant differences in three of their packet of dried mushrooms, enough to mark them as new species.
Their work also highlighted the use of modern DNA sequencing technologies for identifying species in food, and for monitoring foods for quality and adherence to international regulations, such as the Convention on Biological Diversity.
Fungi really are fascinating
Like an apple, a mushroom is the fruit of the fungus. It’s not the apple tree.
Most of the fungus grows below the ground, in a vast network of root-like tubes called hyphae. How vast, you might ask? Well, in a case known as the “humongous fungus”, a single clone (individual) of the honey mushroom (Armillaria ostoyae) has been shown to cover more than 900 hectares in Malheur National Forest in Oregon, USA. Estimates place the age of this gigantic fungal network at more than 2,000 years.
In Australia, some of our fungi are a little more modest in size, though perhaps bigger than you might guess. Nicole Sawyer and John Cairney at the University of Western Sydney have estimated the size of individuals of the Australian Elegant Blue Webcap (Cortinarius rotundisporus) at more than 30m in diameter – about the size of tennis court.
Despite the impressive size of some species, new species of fungi don’t get the same recognition as a new species of mammal, bird or reptile. But discoveries of novel species are the new norm in modern mycology – a change being driven by advances in our ability to sequence DNA.
It’s very important to better understand fungi, as they underpin the terrestrial biology of Earth. They associate with the vast majority of plants in a symbiosis called mycorrhiza.
Living both within plant roots, and out in the soil, they gather nutrients for the plant, and protect it against diseases and water stress, enhancing plant growth in exchange for sugars the plant produces via photosynthesis.
Without their fungal assistants, plants as we know them would not exist. Other fungi are vital decomposers and return nutrients stored in organic matter to the soil. While the most fungi are beneficial, some fungi are devastating plant pathogens, while a small number of fungi can cause disease in humans such as ringworm, trichosporonosis or aspergillosis.
Close human relationships
Humans have also recruited an array of fungi to their cause. Products produced by fungi are used in medicine – many antibiotics come from fungi – and the production of a range of food products including soy sauce, blue cheese, bread, beer and wine.
Numerous new fungi related to Malassezia (a yeast that causes dandruff in humans) have been found in marine subsurface sediments in the South China Sea by Chinese researchers from Zhongshan (Sun Yatsen) University, while scientists from the Woods Hole Oceanographic Institution in the US found the same Malassezia-like species from the Peru Trench in the Pacific Ocean.
The work in the Peru Trench used environmental RNA sequencing to guarantee that sequences observed were from environmental samples, and not contaminants from human skin.
Recent advances in modern DNA sequencing technology routinely yield millions of DNA fragments (reads) that can be quickly and accurately identified using classification tools. One such tool is the recently released Warcup ITS fungal identification set developed by CSIRO scientists in collaboration with the Ribosomal Database Project (RDP) and partners from the Western Illinois University and the Los Alamos National Laboratory in the US.
The Warcup ITS dataset allows identification, to species level, of thousands of ITS sequences within minutes.
The use of modern DNA technologies and classification tools may allow development of bioactive compounds for medicine, enhanced agricultural productivity, environmental damage repair, industrial applications such as biofuels and enzymes, along with food identification and potentially new food sources … sometimes in places you’d least expect.

The current outbreak of Ebola virus in West Africa is unprecedented in size, with nearly 4,800 confirmed or probable cases and more than 2,400 deaths. People have been infected in Guinea, Liberia, Sierra Leone, Nigeria and Senegal.
A second completely independent and significantly smaller Ebola virus outbreak has been detected in the Democratic Republic of the Congo.
Like all viruses, the Ebola virus has evolved since the outbreak began. So, how does this occur and how does it impact our attempts to contain the disease?
Ebolavirus and the closely related Marburgvirus genera belong to the Filoviridae family. Both of these genera contain viruses that may cause fatal haemorrhagic fevers.
The Ebola virus genus is made up of five virus species: Zaire ebolavirus (responsible for both of the current outbreaks), Sudan ebolavirus, Reston ebolavirus, Bundibugyo ebolavirus and Taï Forest ebolavirus.
In order to better understand the origin and transmission of the current outbreak in West Africa, researchers from the Broad Institute and Harvard University, in collaboration with the Sierra Leone Ministry of Health, sequenced 99 virus genomes from 78 patients.
The study, reported in Science, shows the outbreak resulted from a single introduction of virus into the human population and then ongoing human-to-human transmission. The scientists reported more than 300 unique changes within the virus causing the current West African outbreak, which differentiates this outbreak strain from previous strains.
Within the 99 genomes sequenced from this outbreak, researchers have recorded approximately 50 other changes to the virus as it spreads from person to person. Future work will investigate whether these differences are contributing to the severity of the current outbreak.
These 99 genome sequences have been promptly released to publicly available sequence databases such as Genbank, allowing scientists globally to investigate changes in these viruses. This is critical in assessing whether the current molecular diagnostic tests can detect these strains and whether experimental therapies can effectively treat the circulating strains.
How does Ebola evolve?
This is the first Ebola virus outbreak where scientists have sequenced viruses from a significant number of patients. Despite this, the Broad Institute/Harvard University study findings are not unexpected.
The Ebola virus genome is made up of RNA and the virus polymerase protein that does not have an error-correction mechanism. This is where it gets a little complicated, but bear with me.
As the virus replicates, it is expected that the virus genome will change. This natural change of virus genomes over time is why influenza virus vaccines must be updated annually and why HIV mutates to become resistant to antiretroviral drugs.
Changes are also expected when a virus crosses from one species to another. In the case of Ebola virus, bats are considered to be the natural host, referred to as the “reservoir host”. The virus in bats will have evolved over time to be an optimal sequence for bats.
Crossing over into another species, in this case people, puts pressure on the virus to evolve. This evolution can lead to “errors” or changes within the virus which may make the new host sicker.
Ebola viruses are known to rapidly evolve in new hosts, as we’ve seen in the adaptation of lab-based Ebola viruses to guinea pigs and mice. This adaptation occurred by passing a low-pathogenic virus from one animal to the next until the Ebola virus was able to induce a fatal disease. Only a small number of changes were required in both cases for this to occur.
While this kind of viral mutation is well known with other viruses, such as influenza virus, we are only truly appreciating the extent of it with the Ebola viruses.
What do the genetic changes mean?
The Broad Institute/Harvard University study reported that the number of changes in genome sequences from this current outbreak was two-fold higher than in previous outbreaks.
This could be due to the increased number of sequences obtained over a period of several months, and the fact that the virus has undergone many person-to-person passes in this time.
However, it will be important to determine if virus samples from early and late in the outbreak have differing ability to cause disease or transmit. The genetic changes may, for example, influence the level of infectious virus in bodily fluids, which would make the virus easier to spread.
Analysing this data will help us understand why this outbreak has spread so rapidly with devastating consequences and, importantly, how we can better contain and manage future outbreaks.
