A climate professor says the Coalition will be forced to replace the climate agencies it's scrapping with similar versions of its own.

The Coalition has abolished the Climate Commission, which was tasked with providing independent public information on the science of climate change.

The government is also expected to axe the Climate Change Authority and the Clean Energy Finance Corporation.

The Climate Change Authority was created to advise the government on emissions-reduction targets, caps and prices, while the Clean Energy Finance Corporation has distributed loans to finance renewable energy projects.

Professor Kevin Parton, from Charles Sturt University, says the Coalition's cuts in the public sector are a short-term measure.

"By the time we get to 2020, which will be where things really change in terms of the impact of climate, we'll end up with the policy that we would've had no matter who is in government, because we'll be forced into a circumstance where we've got to cut back on our emissions in a big and aggressive way," he said.

"Especially as we move into an international agreements on carbon emissions."

Professor Parton says the Clean Energy Finance Corporation has been the most successful climate agency initiative.

"Small businesses that have been set up in areas from solar panels to wind generation to generation of electricity through collecting methane in landfill probably would not have gone ahead without the finance that is available through the Clean Energy Finance Corporation," he said.

"And it's those initiatives that are going to bring us eventually to the technology we need where we are limiting our greenhouse gas emissions."

TONY Abbott has been likened to South African leaders who once claimed HIV did not cause AIDS.

The comparison, by British process engineer Nilay Shah, was reported in The Times of London and reflects the strong interest internationally in the decision to scrap the carbon tax.

Professor Shah, who specialises in modelling low-carbon technologies, made the comparison when launching a report that said the world needed to spend $2 trillion a year by 2050, or 1 per cent of GDP, to limit global warming to 2C above pre-industrial levels.

The Times report said politicians such as the newly sworn-in Prime Minister would be judged as harshly by future generations as those who questioned the medical evidence on AIDS.

"There's an interesting parallel with South Africa in the 90s, where political capital was being made out of HIV denial," Professor Shah said. "Those people must now regret what they did. I suspect that some of the politicians (now arguing against rapid cuts in emissions) will still be around in the mid-2030s and will reflect that they didn't do enough on climate change."

Mr Abbott has said the Coalition government will scrap the carbon tax and spend billions of dollars on direct measures.

He has said he accepts that "climate change is real, and I accept that mankind is making a difference, and I absolutely accept that we need a strong and effective policy to deal with it".

Australia's decision to scrap the carbon tax has come at an inconvenient time for climate-change campaigners, ahead of the release this month of the Intergovernmental Panel on Climate Change updated report.

There is robust international debate about why climate-change models have overestimated actual temperatures.

Traditional owners in the Gulf Country want to work with government and industry to clean up one of the Northern Territory's most toxic legacy mines.

The old Redbank copper mine, south of Borroloola and about 40 kilometres from the Queensland border, closed in 1996 but still leaks copper sulphide into a nearby creek.

Redbank mine creek copper sulphide residue. Vivid colours mark the death of Hanrahan's Creek, downstream from the old Redbank copper mine.

Redbank mine creek copper sulphide residue. Vivid colours mark the death of Hanrahan's Creek, downstream from the old Redbank copper mine.

The tranquil pools that form at Hanrahan's Creek look serene but the unnaturally bright green water and blue encrustations on its banks are telltale signs of high levels of pollution.

The copper sulphide concentration is so high in some sections of the creek that there is no longer anything living in the water.

Ian Pott is a traditional owner and used to swim in the creek downstream before it was poisoned.

He says there used to be turtles and fish in the water.

He is angry about what has happened and frustrated that there is seemingly no-one to blame.

"The companies that were here before failed it and the EPA (Environmental Protection Authority) has a lot to answer for leaving it this long," he said.

"No-one else is being held accountable at the moment because there is no-one else around."

The contaminated water comes from the mine upstream.

When the former owners abandoned it 17 years ago, they did not secure the main pit, and dangerous levels of dissolved metals have been leaking ever since.

Territory Mines Minister Willem Westra Van Holthe has travelled to the site and promised traditional owners it will be a personal priority to fix the problem.

"Redbank mine certainly rates highly as one of the worst legacy mines in the Territory," he said.

"But here we have an opportunity.

"It is a fairly small mine site, not withstanding the legacy is quite great, but there is a real opportunity to get this right.

“So that the traditional owners and all the other stakeholders involved in rehabilitating this site are kept fully informed, we want an open and transparent process in how we formulate the plans to fix this site.”

The Territory Government recently introduced a levy to try and pay for some of the costs of fixing legacy mine problems.

It is expected to raise just over $6 million in its first year.

Mr Westra Van Holthe says some of that levy will contribute to work at Redbank, although he can't guarantee that will happen in the next year.

COUNTING COSTS

But whatever money is spent won't come close to what is needed.

The full cost of rehabilitating the mine is not known because there has been no in-depth research done.

It is estimated to be anywhere between $10 million and $100 million.

Redbank Copper director Michael Fotios says he has been taken aback by the extent of the damage

"We didn't know a lot of the detail; the previous management really was non-existent," he said.

"When the company was reborn, a lot of the old people involved had long gone.

"We are still trying to find a lot of information or detailed information, reports, data about the old mining operation."

The company says it will use some of the capital it has raised for exploration to help fix the problem.

Mr Fotios believes the best hope for the long-term rehabilitation of the site is to restart mining operations.

That prospect is still a long way off.

"I don't think the site is really close to any mining plan laid down; it's at exploration stage," he said.

"There are significant copper resources here [but] it needs a lot more work to really prove up the viability of the mine."

Stuart Zlotkowski owns Wollogarang Station, the pastoral land the mine is on, which spans both sides of the border.

He is not keen on mining resuming but concedes it is probably the only way the site will be rehabilitated.

"We were always told that it would be cleaned up when the mine could afford to clean it up," he said.

"But because the bond they had in place to clean it up was so small, they couldn't force them to do it.

"It's been a ongoing thing, when we were always told over those last 18 to 19 years [that] soon as Redbank could afford to clean it up they would..

"The problem was, they never made any money, or we were told they never made any money, so it has got to this stage."

ROAD TO REHABILITATION

Mr Westra Van Holthe has not said how much the Territory Government will contribute towards rehabilitation.

The first thing it will do, he said, is form a working group with traditional owners.

"There's an enormous amount of engineering that firstly needs to take place here at the site," he said.

"Obviously, there will need to be some treatment done on the pit, and then they can start releasing water.

"We need to get on top of a whole bunch of issues here, including surface water and ground water."

Mr Pott hopes the Government and Redbank Copper will deliver on their promises.

"There's a bit of apprehension here, with all the TOs, because we've had these meetings before with Redbank mines and a few of the government departments but it's good to see the Minister out here," he said.

Mr Westra Van Holthe does not know how many abandoned legacy mines are leeching chemicals into the environment.

He estimates there are more than a thousand, and that it would cost more than a billion dollars to clean them all up.

"One of the things I am not going to do, and the government is not going to do to, is stick our head in the sand over these legacy mining issues," he said.

"Redbank is just one of many, and we will be working very hard to get on top of this, and other legacy mining issues in the Territory."

The Territory Government says it plans to send in dump trucks and bulldozers to begin rehabilitation at Redbank next year.

EPA INVESTIGATION

NT Environmental Protection Authority chairman Dr Bill Freeland says the water at the mine's leaking pit has a PH of two to three, close to the level of battery acid.

He says copper from the mine site has been detected in the water all the way down to the Queensland border.

"You have to go down about seven kilometres before you let livestock drink it, or humans drink it," he said.

"Over that length you've lost most of those macro invertebrates, the little, tiny critters that live in the bottom, which form the basis of food chains for things like fish and so forth."

Dr Freeland defended the EPA against claims of inaction.

"One of the things I did several months after I first got appointed was to make sure we did an investigation to find out what the situation really was," he said.

The results of that investigation are due to be released in November.

THE exotic fish trade presents an ongoing challenge for bacteriologists working to keep harmful pathogens out of WA water ways, but experts say the state’s biosecurity efforts are among the best in the country.

The importation of exotic aquarium fish into Australia is worth around $350 million annually, with 15.5 million fish being imported in 2005.

However, these animals can be a source of exotic pathogens, bacteria and disease that cause havoc in Australia’s freshwater and marine eco-systems.

Fish imported into Australia are subject to Department of Agriculture Fisheries and Forests (DAFF) biosecurity conditions and on arrival are held in quarantine for inspection.

In WA, fish showing signs of disease are sent to the Fish Health Unit at the Department of Fisheries, before bacteriology is conducted at the Department of Agriculture’s Animal Health Laboratories.

Animal Health Laboratories expert Dr Nicky Buller says she regularly receives samples of suspected exotic pathogens which are then subjected to state-of-the-art technology for culturing and identification.

“When DAFF Biosecurity officers observe significant deaths among quarantined fish, we are supplied tissue samples for identification,” she says.

“We perform traditional culture procedures and DNA-based methods, but we also have introduced the matrix-assisted laser desorption/ionization time-of-flight mass spectrometer (MALDI-TOF) for identifying samples,” Dr Buller says.

“This technology utilises the proteins on the cell wall which are ionized by a laser beam and separated under vacuum.

“The mass is recorded on a detector, and the resulting spectrograph is compared to the database to determine a probability whether high or low of it being a certain organism.

“In the last year we have had a few exotic pathogens detected in quarantine and we have been able to identify them through both traditional methods and with this new technology.”

“Culturing” involves growing the bacteria for further study, a process that can present several challenges for researchers.

Bacteria from marine fish need to be cultured in media containing NaCl, or magnesium and potassium ions, whereas bacteria from freshwater fish do not required added NaCl.

“It is a challenging task. You have to be able to recognise potential cases of exotic disease among the endemic cases; bacteria that you wouldn’t normally see in everyday diagnostics,” Dr Buller says.

“There are also specific temperature and media requirements for different bacteria, and that means knowing what temperature is optimum for culturing.”

Dr Buller is urging West Australians to help reduce the risk to Australia’s native fish with practices like disposing of dead aquarium fish in bleach in the household rubbish, rather than flush them down the toilet.

A NEW 18-month research project is under way to understand how oceanographic conditions affect Queensland's reef fish and scallop populations.

The research is a joint initiative of the Queensland Department of Agriculture, Fisheries and Forestry (DAFF), University of Queensland and Bureau of Meteorology, with funding from the Fisheries Research and Development Corporation and Great Barrier Reef Marine Park Authority (GBRMPA).

Lead investigator and DAFF principal fisheries biologist Dr Tony Courtney said by better understanding these environmental influences, improvements to stock assessments can be made and better advice given to Government and fishers.

"There is a strong need to better understand how the prevailing physical oceanography affects these fisheries," Dr Courtney said.

"In recent years, oceanographers have described a large offshore eddy system on the central Queensland coast, known as the Capricorn Eddy, that breaks away from the south-flowing East Australian Current to move westward onto the continental shelf.

"The eddy brings cool, nutrient-enriched oceanic water onto the shelf, which we suspect affects the population size of saucer scallops in the region.

"We will also examine the relationships between tropical cyclones and catch rates of reef fish, given the Great Barrier Reef has been hit by four major cyclones in the last 5 years.

"From commercial fishing data we’ve observed that catch rates of coral trout appear to fall after a major cyclone, while those of red throat emperor rise.

"These changes seem to endure for some years after the cyclone, but their exact causes are not known.

"For coral trout, it's thought the cooler waters that result from cyclones may slow down the metabolic rate of the fish, thereby affecting their feeding behaviour and ability to be caught by fishers."

The types of oceanographic data to be considered include sea surface temperature, satellite-based chlorophyll measurements, sea surface height, salinity, current strength and direction, and radii and wind speeds of tropical cyclones.

The project will use CSIRO's Bluelink ReANalysis (BRAN) 3.1 oceanograhic model of ocean temperature, salinity, currents and sea level height. It will also use fish and scallop population data including commercial fishing logbooks, underwater visual survey data and age and size data from the Australian Institute of Marine Science, GBPRMA, James Cook University and DAFF.

The study includes funding for a post-graduate student to examine fish and scallop larval dispersal patterns.

For further information on the project, contact DAFF on 13 25 23.

Possibly the most poignant irony of the federal election was to see the outskirts of Sydney burn while the votes were still being counted. While no records had been broken in the election itself, we saw yet another record for extreme weather events: the hottest start to spring in Sydney since records began.

And with these fires, this irony quickly turned to farce, as the News Corp press launched a new kind of offensive on carbon reduction policies by singling them out as the sole cause of Labor’s loss.

On the front page of the Weekend Australian, the services of former ACTU secretary Bill Kelty were enlisted to endorse the thesis that the carbon tax was responsible for Labor’s punishment on polling day.

Does this argument make sense? Yes, if you look at the influence of climate change denialism in the Murdoch press. No, however, if you examine the carbon politics leading up to the election and the surveys measuring the importance of carbon reduction to Australian voters.

Carbon politics

Kevin Rudd’s first step in taking back the Labor leadership was to neutralise something called a “carbon tax” as an issue. Voters had long forgotten that the so-called tax was introduced as an emissions trading scheme in November 2011. It was Abbott and the press that later labelled it as a tax, setting up the mantra to “get rid of the tax”.

But because of the effectiveness of the mantra, Rudd’s focus groups told him to bring forward the abolition of the fixed price on carbon trading himself, which he did.

If anything, it is more likely that Labor’s constant backflips on carbon policy translated into the protest vote that went to the Greens, not the Coalition.

Abbott could see this by the final week and, after having said barely anything about carbon policies except for the slogan, suddenly declared that the election was “all about carbon”.

And this final message of Abbott’s campaign has now been echoed by the News Corp press, both in Australia and overseas. There is now a manufactured but concerted campaign to make carbon policy and global warming an issue that is guaranteed to lose an election for any party that dares take it on.

Last Monday in Murdoch’s Wall Street Journal, the editorial was entitled Aussie Restoration: The perils of a carbon tax and other lessons from Down Under. It made a pitch not seen before in News Corp papers: an editorial-led push to banish climate change reform from electoral politics altogether. US politicians were advised:

One lesson is to beware the faddish politics of climate change’ which supposedly proved to be a turn-off for voters who ‘will figure out that the politicians are merely looking for one more way to tap into their incomes.

Whilst we have seen the Murdoch press aggressively oppose climate change reform and consensus science systematically for years now – in parallel with extremely wealthy private think tanks and lobby groups – we have not witnessed this kind of attempt to scare politicians off dealing with climate change. The US website Media Matters even reports the case of a US senator who has avoided climate change legislation for fear of facing the wrath of Fox News' ongoing campaign against climate change action.

Importance of carbon policy to voters

But actually, climate change is important to mainstream voters, and Abbott himself knows this. He personally may not believe it, but he does believe that a majority of Australians are concerned about it. Activists often quote Abbott’s famous Beaufort speech where he declared that the argument for human-forced climate change is"‘absolute crap" but fail to quote the next two sentences:

However, the politics of this are tough for us. Eighty per cent of people believe climate change is a real and present danger.

Hence, Abbott will retain some kind of minimalist policy toward the issue, as long as the surveys are showing voter concern about it.

As of August 27, the ABC’s successful Vote Compass survey of 900,000 participants found that 61% of Australians believe the government should do more to tackle global warming. And in case you think that this just reflects an ABC audience that is assumed to mirror a Left political class, Vote Compass also handily breaks down the doing-more-about-climate-change question into Green Voters (82% support), Labor (71%) and Coalition (24%).

A CSIRO survey on the importance of climate change to individuals conducted in late 2011 showed that 65% of Australians believed climate change was either “somewhat”, “very” or “extremely” important. The 22% that believed it was not that important strongly correlated with a view that climate change was happening but that it was “natural”.

But you wouldn’t know this from reading News Corp papers. News has been consistent in peddling climate change denial for almost five years now. The difference now is that there is an attempt to influence the political process directly by labelling it an issue for political losers. To the extent that this is true, Australia and the US (the two countries that did not sign up to Kyoto from the beginning) really are heading down the road of climate policy suicide, which will one day be held up to ridicule by the rest of the world, where it hasn’t been already.

Of course, as many commentators point out, carbon tax, ETS, CPRS, (take your pick) are not as important as the carbon footprint created by Australian coal exports. And they are right. But at an ideological level of struggle, carbon reduction policies connect symbolically with crucial questions of public awareness, ongoing initiatives in the future, civic responsibility, and policy around renewable energy.

That carbon reduction could possibly become a taboo topic, right at the moment when the earth’s energy imbalance is more visibly translating into some of the most extreme weather we have ever seen in Australia is as inconceivable as it is farcical.

The Northern Territory Environment Centre says it is concerned about the speed at which licences to tap underground water reserves are being applied for by irrigators.

Four applications were advertised this week, seeking a total of 15.7 billion litres of water from the Ooloo aquifer, which feeds the Daly River.

Environment Centre director Stuart Blanch says that would increase the current allocations of water by 60 per cent.

He says irrigators are racing to secure valuable water licences in the Katherine region, about 300 kilometres south of Darwin, before they run out.

"This is a harbinger of what's to come, with a massive northern food bowl push," he said.

"I think a lot of fishermen, traditional owners, river communities downstream and environmentalists will say the Daly is coming under increasing pressure from water extraction.

"It's a race to get whatever water they can for free.

"People, I think, are ignoring the concern of scientists, people living downstream who use the healthy river, and they just want to get in before they lose out."

Sandalwood supplier TFS has applied for a extraction licences of 13 billion litres from the southern and northern sections of the Ooloo aquifer.

Earlier this year, there was controversy when an application to draw up to 5.8 gigalitres of water a year was granted to Stylo Station near Mataranka, about 100 kilometres south of Katherine, from the Tindall aquifer.

The Tindall aquifer feeds the Roper River.

The Stylo Station licence is by far the largest in the area.

The property is owned by the family of Country Liberals federal election candidate Tina MacFarlane, who is now waiting for the results of counting of the final votes for the seat of Lingiari.

Labor's Warren Snowdon remains marginally ahead.

The MacFarlanes say they want to use the water for irrigation.

BURNETT MP Stephen Bennett is calling for an investigation into the fishing practices of trawlers off the coastline after hundreds of dead fish washed up between Bargara and Burnett Heads.

A number of dead fish have been washed up on Mon Repos Beach. Photo: Mike KnottResidents reported sighting hundreds of dead fish lining the beach in front of Mon Repos Turtle Rookery on Monday and a small amount still remained there on Tuesday.

A spokesman for the Department of Environment and Heritage Protection said the site had been inspected and the dead fish were identified as puffer fish.

"The fish are likely to have washed up on the beach as trawler by-catch," he said.

"There was a similar incident of fish deaths last week which was also thought to be the result of trawler by-catch."

Mr Bennett said he was outraged by the problem.

"It's disgraceful," he said. "I will be asking the local fisheries department to look into this.

"Fish kills on this scale are unacceptable."

Mr Bennett said there was extra trawling activity at the moment.

"There is a lot of trawling activity off the coast and we did open things up to trawlers north of the Burnett River to Rules Beach temporarily because the industry was on its knees after the floods."

"As a result of that we are seeing increased activity off the coast. I think we do need to be a little bit concerned about this though."

Mr Bennett said while the fish may not be edible, there was no excuse for so many turning up dead.

"There is a cost to the environment," he said. "They still have a role to play in the ecosystem."

Mr Bennett said he would be making further inquiries.

"We have to make the assumption that it is by-catch," he said. "I will take a personal interest in finding a more tangible explanation."

As we face a choice tomorrow between two parties whose environment policies are incomplete at best, we must consider how we will explain to our grandchildren how we let Australia's threatened species disappear.

LET'S CALL IT LIKE IT IS: this has been a woeful election for the environment. The environment has barely rated a mention in this campaign, which makes it all the more ironic that we go to the polls on National Threatened Species Day.

Commemorated each year on September 7 it marks the day in 1936 when the last Tasmanian tiger died in a Hobart zoo. The old black and white film of that animal pacing in its enclosure is haunting and tragic. It makes you ask aloud in disbelief "how did our grandparents let that happen?"

Yet 77 years later we face our own environmental watershed moment. Future generations may well ask the same question of us. There is a lot at risk.

The possible wind-back of the Howard Government's Environmental Protection and Biodiversity Conservation Act could expose our threatened species to rampant development without the necessary checks and balances.

We could see increased destruction of species habitat - putting more pressure on koalas. There is the threat of dredging on a massive scale and the dumping of dredge spoil onto our Great Barrier Reef.

Then there is climate change. Scientists fear the pace of warming could make it near impossible for species and wilderness areas to adapt. We could lose up to 30 per cent of species if we don't act and temperatures are allowed to rise three degrees.

Australia is one of the most biologically blessed nations on earth. We are rich in environmental wonders, unique wildlife and natural resources. Today, it's our responsibility as Australians to protect them.

Debate over our future economic prosperity features as a first order issue this election but a strong economy depends on a healthy environment.

Take the Great Barrier Reef for example. A $6 billion tourism industry and 60,000 jobs depend on a healthy reef. The misconception that it is a choice between the environment or economy leads to entrenched positions rather than a focus on sustainable solutions. The science shows that the future of the reef as we know it is at risk if we don't intervene. Coral cover is projected to drop below 10 per cent in the next 10 years - a loss of over 70 per cent since the 1960s.

Pollution from chemical fertiliser runoff is a key driver in the decline of the reef as it feeds outbreaks of coral-eating crown-of-thorns starfish. Government has provided some funding to help farmers help the reef by cutting fertiliser run-off, but far deeper investment is needed to halt and reverse the decline.

Industrial dumping of millions of tonnes of dredge sludge and waste is also putting our reef at risk. It could even lead the World Heritage Committee to list the reef as 'World Heritage in danger'. Such an outcome would be Australia's day of shame.

In the last seven days we have started to see the major parties realise that we must ensure we have good policies, plans and funding in place for the Great Barrier Reef.

Last week, the Environment Minister, Mark Butler, announced ALP policy to extend the successful Reef Rescue program, a major initiative in cutting polluted farm run off. This week, Shadow Environment Minister, Greg Hunt announced the LNP Reef 2050 policy which largely matches the Reef Rescue program but also launches a new initiative called the Reef Trust. The trust is designed to generate significant new public and private funds to repair the reef and we recognise the coalition has a strong legacy when it comes to protecting the reef.

Of course the elephant in the room is that neither party has committed to a ban on industrial-scale dumping of dredge waste in the Great Barrier Reef World Heritage Area. During this campaign the only announcement of a policy to ban dumping was made recently by Senator Christine Milne of the Greens.

But it's not just our precious wildlife under threat, climate change impacts on us all - our society, our economy, even our health - it affects everyone.

The major parties are currently committed to a minimum target of five per cent by 2020. Their current policies state they will consider increasing to 25 per cent, but only if other countries do more. Other countries are doing more and scientists say countries like Australia need targets of between 25-40 per cent by 2020 to avoid the worst of climate change. Despite that the major parties remain silent on more ambitious targets.

The next Australian government has a chance to address the threats to our environment, and leave a legacy of which future generations can be rightly proud. Our economy is not sustainable if we don't protect the natural assets on which it is based.

History has shown that leaders have done it before. Remember the Howard Government protecting a third of the Great Barrier Reef Marine Park for conservation or the Hawke Government saving the Franklin River from being dammed. Australia has a track record of showing environmental leadership on the world stage.

On 7 September, National Threatened Species Day, we will get to have our say. But our animals and the places we love won't. Our next government will need to embrace a sustainable Australia.

We don't want our grandchildren looking at old vision of the reef or at koalas and asking aloud in disbelief "How did my grandparents let them disappear?"
