The ConversationBy Rod Lamberts, Australian National University at The Conversation

A colleague of mine recently received an invitation to a Climate Council event. The invitation featured this Tim Flannery quote: “An opinion is useless, what we need are more facts.”

My first thought was that my colleague was taking the piss. Tim Flannery is an experienced science communicator, but that phrase made my jaw drop. It was apparently meant in earnest, but it’s wildly off the mark.

The quote is ludicrously, appallingly, almost dangerously naïve. It epitomises the reasons we are still “debating” climate science and being overwhelmed by climate skeptics/deniers/contrarians in the public space.

My intense frustration about the current state of the climate issue is shared by Climate Change Authority chairman Bernie Fraser, who says the public has been left confused and fed up because deliberate misinformation has been allowed to spread unchecked.

But the “more facts” solution is no solution at all. We have enough facts now and none of them are good. Yet here we are, in Fraser’s words, watching the “bad guys” win.

Communication without opinion?

Opinions are a cornerstone of human communication. They may be based on obvious, acceptable, objective evidence, or they may not. There will be opinions with which you agree, disagree, or don’t care. Regardless, they are intrinsic to the way humans interact – at work, chatting over dinner, everywhere.

By asserting that opinions are useless in climate change communications, Flannery might as well be saying we should stop using language at all.

It’s as disappointingly innocent as the cries I’ve heard regularly from scientists who want us to “leave the politics out of climate change”.

Like opinion, politics is not an “add-on”. It’s the way we decide things as a society. It’s unavoidable when more two or more people have competing plans for the same resource.

That’s why decrying the usefulness of opinions is simply irrelevant. Opinions just are. They exist. We use them all the time, and perhaps nowhere more vehemently than when bashing out positions in the world of politics, advocacy or activism.

To top it off, Flannery’s assertion about the uselessness of opinions is itself an opinion, so by his own logic, useless.

To facts

If there’s one thing decades of advertising, public relations, psychology research and science communication have taught us, it’s that throwing facts at opposing opinions with the hope of changing people’s minds is like playing golf with a pineapple: it’s not just useless, it’s actively counterproductive.

At best, presenting people with facts to counter their beliefs makes them ignore you; at worst, it drives them further away. How much more evidence do you need than the singular failure of scientific facts to convince deniers that humans are buggering up the climate?

It’s a bit like this classic caricature of old-school British colonialism:

Lord Ponsonby: “How do you speak to the natives?

Lord Snot: “In English, of course”

Lord Ponsonby: “What if they don’t understand?”

Lord Snot: “I speak louder”

Time for action

The fact is that the time for fact-based arguments is over.

We all know what the overwhelmingly vast majority of climate science is telling us. I’m not going to regurgitate the details here, in part because the facts are available everywhere, but more importantly, because this tactic is a core reason why climate messages often don’t resonate or penetrate.

If, like me, you’re convinced that human activity is having a hugely damaging effect on the global climate, then your only responsible option is to prioritise action.

Why, then, do so many who represent the experts, the science, and the evidence seem to prioritise their perceived moral standing as a scientist above all else?

What’s worse: being convinced bad things are happening and resorting to “unscientific” means that inspire real action, or watching things go to hell while taking comfort in the knowledge you were a worthy, well-behaved scientist who didn’t stoop to getting political?

Ultimately, we can only say “that’s not cricket” for so long. Eventually we have to stop tutting and accept that others aren’t even trying to play cricket – they’re boxing. We can decry climate deniers for their unfair, lowbrow tactics, but their tactics are getting them exactly what they want. Ours are not.

The continuing focus on gathering and presenting more and more scientific data to reinforce a position the vast majority already holds is not leading to the changes we need. Yes, scientists should keep monitoring, researching and reporting on the climate. But assuming that we want people to act according to the science, the focus must now be on influencing positive action.

So, what now?

There’s no profit in trying to change the position of deniers. Their values and motivations are fundamentally different to those of us who listen to what the weight of scientific evidence tell us. So forget them.

Forget the Moncktonites, disregard the Boltists, and snub the Abbottsians. Ignore them, step around them, or walk over them. Drown them not just with sensible conversations, but with useful actions. Flood the airwaves and apply tactics advertisers have successfully used for years.

What we need now is to become comfortable with the idea that the ends will justify the means. We actually need more opinions, appearing more often and expressed more noisily than ever before.

The biggest impediment to climate action these days is not because of the human frailties that science is hell-bent on resisting – those alleged failings of opinion, belief and emotion. Ironically, it’s exactly because we are still trying to suppress them that we are now stalled.

QFASThe Queensland Federation of Aquarium Societies (QFAS) is holding another combined clubs super auction this Saturday!

The combined clubs auctions are some of the biggest events on the aquarium hobby calendar for the greater Brisbane area. At QFAS Super Auction you can expect to see a lot of speciality fish, plants, aquarium furnishings, and lots of other hobby related odds and ends – much of which you’re not likely to find in a pet shop. Many club members maintain lineages that aren’t available commercially and/or regularly produce champion fish for our local shows, and bring their surplus along to the auction. It’s a great social outing and if you’re new to the hobby, a great opportunity to seek out some advice, with more fishkeepers in one place than you’d hope to see anywhere else. There’s bound to be plenty of bargains. As well as independent hobbyists there’ll be plenty of members from:

  • Betta Australis;
  • Queensland Aquarium Hobbyists;
  • the Queensland Cichlid Group; 
  • the Gold Coast Aquarium Society; and of course
  • ANGFA Qld.

There’ll be plants, live foods, Australian & PNG natives, Africans, Americans, Bettas, livebearers, catfish, community tropicals and who knows what else… And it’s all staffed by volunteers, so all of the funds raised through commissions and the canteen go directly towards supporting the clubs that support the hobby.

If you are Selling enter via Kate Street where the signs for Indooroopilly Montessori & RiverGlenn (seller check in from 2:00-5:00pm). Follow the road around to the pool on your left, there is a small bus shelter on right for drop off and hall is behind. There are 2 paths the one on the right hand side doesn’t have steps.

If you are buying or just looking go to Witton Road into Bridge street Car park on the right.

Nudgee Junior College, Kate st Indooroopilly.
Fish & other items in at 2.00pm-5pm. Auction starts 4.00pm.

Aquatic ecologist Adam Kerezy has been working for years to save the tiny red-finned blue-eye fish [Scaturiginichthys vermeilipinnis] from extinction.

It is only found in natural springs in central western Queensland.

Dr Kerezy says it is also seeking permission to move some of the remaining fish into captivity.

“So they only get to about three centimetres long, they only live in that particular group of springs north-east of Aramac,” he said.

“The crucial thing is we have got an invasive species called gambusia, or mosquito fish or bore drain fish, and they are out there too and so my job over the last six years has been basically to try and stop them [red-finned blue-eye fish] from going extinct.

“Hopefully they will be breeding up a bit, some of them will be trying to move to new springs.

“Hopefully this year we will move some into captivity and then cross fingers and toes and everything we have got and hope that they survive but for a fish that has adapted to living in these tiny shallow springs in the middle of nowhere, it might take a little bit of work to get them to adapt to captive conditions.”

Australia has successfully hatched its first shark born via artificial insemination with hopes that the development can ultimately be used to help breed threatened species, an aquarium said Wednesday.
The first brown banded bamboo shark pup born in Australia via Artificial Insemination is shown a at the SEA LIFE Melbourne Aquarium on March 2, 2014

The first brown banded bamboo shark (Chiloscyllium punctatum) pup born in Australia via Artificial Insemination is shown a at the SEA LIFE Melbourne Aquarium on March 2, 2014

Sea Life Melbourne Aquarium said the brown banded bamboo shark pup was born on March 3, ending a process which began in September when aquarists collected a semen sample from a shark in Mooloolaba in northeastern Australia.

This was flown to the southern city of Melbourne and inseminated into the mother the same day—making the pup the first shark to be born globally via a live semen sample transported from one facility to another, Sea Life said.

Melbourne Aquarium vet Rob Jones said the birth of the shark—which is expected to grow from its initial length of 16 centimetres (6.3 inches) to an adult size of 1.2 to 1.5 metres—was a milestone in using assisted reproductive technologies.

“This is a big leap,” he told AFP.

The hatching is part of a nine-year project into understanding the reproductive behaviours of , animals which are common in Australia but are little understood.

The team hope their research will help with plans to manage threatened species in the wild, in particular the critically endangered grey nurse shark.

The egg, one of several laid by the shark in November but the only viable one, was monitored weekly during its incubation period of 112 days.

“With each insemination attempt, we continue to learn about the reproductive behaviours of Australian shark species,” said Melbourne Aquarium research consultant Jon Daly.

“Hopefully we can use this technology as a basis for breeding grey nurse sharks in captivity and, in years to come, boost the species’ dwindling numbers in the wild.”

Grey nurse sharks are considered critically endangered, with estimates that there could be as few as 1,500 left on Australia’s east coast.

Sharks are a known danger for those swimming, diving and surfing around the country and are currently subject to a controversial cull in Western Australia state after a series of fatal attacks in recent years.

The policy to catch and kill any protected great white, tiger or bull shark bigger than three metres off popular west coast beaches has been condemned by conservationists.

Investigations are underway into the cause of a large fish kill at a central Queensland waterway.

More than 1,500 fish have washed up dead at Hood’s Lagoon in Clermont since yesterday morning.

Isaac council acting chief executive Scott Riley says the issue is not related to water quality problems at Dysart.

He says council workers have observed fish gasping for air.

“I think the issue we are dealing with in Clermont is more of a routine maintenance type of issue that’s linked to the normal maintenance of the town’s supply system, whereas in Dysart, it’s been a water quality issue in terms of the defined supply via the pipeline,” he said.

He says it could be linked to stormwater contamination.

“We have observed fish that have been gasping for air which indicates there may be low levels of oxygen … in the water,” he said.

“It appears that there may have been an event where low oxygen levels were caused when we installed essentially some backwashing of stormwater lines.”

Original story by Elise Worthington, ABC News

Queensland researchers are working on a world-first frog breeding program to stop the tiny, endangered tinker frog from becoming extinct.

Two of the six species of tinker frog have already been wiped out, and researchers believe the lethal amphibian Chytrid fungus is to blame.

The one- to two-centimetre-long frog, which is native only to Queensland rainforests, gets its name from its unique call, according to Professor Jean-Marc Hero from Griffith University.

“The thing that really makes them stand out is their tinker, the sound they make is like the tinker of a glass jar with a metal pen or something,” he said.

Professor Hero says a new program on the Gold Coast has managed to breed the tinker frog for the first time.

“There are only six species – they are an ancient Gondwana group – and at least three of those are already gone,” he said.

“We are looking to recover and support the species that are remaining.”

There are only six species – they are an ancient Gondwana group – and at least three of those are already gone.

Professor Jean-Marc Hero

Saskia Lafebre from Currumbin Wildlife Sanctuary on the Gold Coast says it is an exciting development.

“The species that we are working with are almost endangered in their own right, but we are actually trying to work with these species so we can one day work with the more endangered species of tinker frogs,” she said.

Ms Lafebre says it will be around two years before the new tadpoles can breed, but if all goes well there could be up to 400 tinker frogs hopping around.

“We’ve got large numbers of eggs, large numbers of tadpoles and hopefully we can turn that in to large numbers of metamorphs,” she said.

Tinker frog’s breeding behaviour unusual

The tinker frog is part of the genus Taudactylus, which has unusual breeding behaviours that have made life difficult for researchers.

Unlike other species, the tinker frog likes to lay its white eggs underground because they have no pigmentation, which leaves them susceptible to sunburn.

“We made a little bit of a mistake, where the eggs got some sunlight and they were killed almost immediately,” Professor Hero said.

He says things have improved this year with hundreds of tadpoles spawned from a number of adult frogs.

“It’s quite an unusual frog it has unusual behaviour and we are very lucky to be finally very successful in breeding them,” he said.

The breeders hope that those frogs will then be able to breed and create a large, captive population.

“It’s very important that we learn how to breed these species in captivity so we can save them from extinction,” he said.

Deadly skin fungus attacking other frogs

The tinker, like many other types of frogs across the world, has fallen prey to the deadly skin fungus Chytridiomycota, which causes the animals to die from heart failure.

Professor Hero says researchers are still trying to establish how the fungus spreads, to avoid reinfecting the new tinker frogs.

“The fate of the animals is still yet to be determined because we are still struggling with what is the cause of the decline in these animals,” he said.

“It’s hard to know at this stage where these frogs are first infected by the zoo spores of the lethal fungus that kills them, but it’s certainly in water and probably most likely the tadpole stage.

“We have to be really careful before we re-release them into the wild that they are not infected with that disease.”

The construction of wetlands has an important role to play in strategies to offset the loss of natural wetlands and treat wastewater. Typically, the effectiveness of constructed wetlands is assessed by comparing their levels of species abundance and diversity with those in natural wetlands. However, these structural indicators aren’t necessarily good measures of ecosystem function. In a study of riparian locations on the Ebro River in Spain, net ecosystem production (NEP, the balance between primary production and community respiration) was measured in matched sets of natural and constructed wetlands. Analysis revealed that water column NEP was significantly higher in natural than constructed wetlands. In the natural wetlands, NEP was highest in unvegetated habitats,while in the constructed wetlands NEP tended to be greatest in habitats dominated by submerged plants, particularly the branching alga Chara. Because previous work showed that invertebrate communities recovered rapidly in the same constructed wetlands, the new results suggested that ecosystem function recovered more slowly than ecosystem structure. Therefore, useful insights may be gained by including ecosystem function in the design and evaluation of new wetlands.

Original story by Damien Murphy and Amanda Hoh, The Sydney Morning Herald

Every surfer who pulled up at a beach to check the waves has known the universal disappointment that goes with being told ”you should have been here yesterday”.

The phrase became part of beach lingo in the first surf film to cross over into the mainstream, Bruce Brown’s The Endless Summer.

Fifty years later, ”you should have been here last century” looks like being the new reality for surfers who chase storm surf.

Latest findings by the Bureau of Meteorology predict big surf will increasingly become a thing of the past. Andrew Dowdy, lead author of a study for the bureau’s Centre for Australian Weather and Climate Research, said fewer large waves were projected for eastern Australia because storms were not going to be as hostile. But while bad news for big wave riders, there was a bright side: the wave research was carried out partly due to increased concern with coastal erosion and rising sea levels.

”Our study was focused on storm waves. We found increasing greenhouse gases will likely reduce the number of storm waves for central east coast of Australia for the end of this century,” Dr Dowdy said.

The bureau researchers took readings from wave observation buoys located six to 12 kilometres offshore from Coffs Harbour to Eden on the south coast and collated it with data and conditions high in the atmosphere about five kilometres above sea level.

”It was a new method that provided a really good indication of the risk of large waves occurring,” Dr Dowdy said. ”We used climate models that could represent those conditions … that [showed] us how that might change in the future. They proved more consistent than previous studies, as well as allowing the influence of greenhouse gases to be clearly shown.

”It all comes down to how much greenhouse gases are in the atmosphere. We had one scenario where greenhouse gases continue to rise towards the end of the century, and another where greenhouse gas emissions stabilised. For a higher emission scenario, we can expect a 40 per cent reduction in storm events. If emissions were stabilised, we can expect 25 per cent fewer storms in the region.”

Having endured the worst year for quality surf in 60 years, surfers living along the NSW coast, but especially around Sydney, are under little illusion that something has stopped sending surf onto their beaches, points and reefs.

Maroubra surfer Richie Vaculik said the past year had been the worst for surf in years. ”You look back [to] when you were a little kid and seem to think there was always big surf, but last winter hardly any of the big wave spots – Ours [Cape Solander], Fairy Bower [Manly], the bombies around Queenscliff and Ulladulla – fired at all,” he said.

Original story compiled by Kev Warburton, Freshwater Research News

Which aquatic species are the most vulnerable to the impacts of climate change? In theory, traits such as physiological tolerance, life history attributes, dispersal abilities and dietary and habitat requirements could be useful indicators of the vulnerability of a species to climate warming, but this possibility needs to be tested for different types of organisms. One such analysis focussed on the freshwater fish of the Murray-Darling river system in Australia, and drew on monitoring data for 39 species, plus data on 14 biological traits for the same species compiled from the literature. Of those traits, 11 showed a significant relationship with changes in species abundance observed in 2004-2010 during a period of extended drought. Trait-based rankings of drought vulnerability also agreed well with species vulnerability assessments from previous studies. The most vulnerable fish species had relatively low heat tolerance and low minimum spawning temperatures. They tended to be small-bodied species (e.g. galaxiids, pygmy perches) that feed on invertebrates, which suggested that omnivores that consume more detritus and plant material have more success in finding food during drought. Vulnerable species also tended to mature early and have a short life-span, an extended spawning season and low fecundity. These are normally considered to be “opportunistic” features typical of species adapted to unpredictable environments, but it seems that that this type of opportunism doesn’t extend to coping with long, multi-year droughts. In prolonged droughts, larger species with delayed maturation are better equipped to survive and breed later. Vulnerability rankings based on a range of traits can help to identify species at risk and prioritise conservation actions.
