Tony Abbott’s insistence that bushfires aren’t linked to climate change is like the tobacco industry claiming smoking doesn’t cause lung cancer, Nobel laureate Al Gore says.
In light of the New South Wales bushfire disaster, the former US vice-president says the prime minister’s comment that bushfires are a function of life in Australia and nothing to do with climate change reminds him of politicians in the US who received support from tobacco companies, and who then publicly argued the companies’ cause.
“For 40 years the tobacco companies were able to persuade pliant politicians within their grip to tell the public what they wanted them to tell them, and for 40 years the tragedy continued,” Gore told ABC TV’s 7.30 program from Los Angeles on Wednesday night.
“Bushfires can occur naturally and do, but the science shows clearly that when the temperature goes up and when the vegetation and soils dry out, then wildfires become more pervasive and more dangerous.
“That’s not me saying it, that’s what the scientific community says.”
Gore said it was a political fact of life that politicians and commercial enterprise colluded to achieve goals after he was asked if there was a conspiracy between polluters and politicians.
“I don’t think it’s a commercial conspiracy. I think it’s a political fact of life,” he said. “It certainly is in my country. In the United States, our democracy has been hacked.
“Special interests control decisions too frequently. You saw it in our recent fiscal and debt crisis.
“The energy companies, coal companies and oil companies particularly, have prevented the Congress of the United States from doing anything meaningful so far, to stop the climate crisis.”
The Nobel laureate said Australia’s new Direct Action strategy was not workable.
“The meaningful way to resolve this crisis is to put a price on carbon and in Australia’s case, to keep a price on carbon,” he said.
He argues the price needs to be at an effective level with the market sending accurate signals so that renewable systems of energy are encouraged.

After years of debate, fiery protests and intense negotiations, Australia has adopted a historic plan to restore flows to the suffering Murray-Darling River Basin.
It is one of the boldest water pacts to restore nature on the books, and if successful, could offer a roadmap for overtapped river basins in other arid lands.
The plan aims to return 3,200 billion liters of water – about 13 percent of the Murray’s average annual flow – to the river system, which spans 14 percent of Australia’s territory, supports 39 percent of its agricultural production, and harbors 30,000 unique wetlands – 16 of them internationally recognized. The basin is also home to the prized Murray cod, whose population has been decimated by excessive river diversions and many years of drought.
In signing the plan into law on November 22, federal environment minister Tony Burkeproclaimed, “There’s always been an excuse to delay. Delay ended today. We now have a national approach to the Murray Darling Basin.”
For Australia, the river basin plan represents an ambitious attempt to rebalance water use between farms, cities and ecosystems. It sets flow targets across the four basin states – Queensland, New South Wales, Victoria and South Australia – and establishes caps on river diversions to ensure those environmental flows are met. Those caps, or “sustainable diversion limits,” go into effect in 2019.
The Commonwealth government has already secured the majority of the water needed to execute the plan through investments of some $11 billion, most of them to buy water back from willing sellers. But because of their effects on rural jobs and economies, those buybacks are highly controversial, and farmers and rural communities are hoping most of the remaining water needs will come not from additional water purchases, but from water efficiency improvements.
Toward that end, the Commonwealth has committed to spending an additional $1.8 billion on irrigation infrastructure upgrades and smarter water management, and Minister Burke is looking to the states to identify projects where those water savings can be realized.
For its part, much of the Australian conservation community is skeptical about the plan’s ability to succeed, arguing that at least 4,000 billion liters of water are needed to bring the river system back to health. The exclusion of groundwater pumping from the plan also raises concerns. Because groundwater provides base flows for the river, increased groundwater extractions could reduce river flows, offsetting some of the plan’s restoration gains.
Full implementation of the plan will take until 2024, so only time will tell whether the plan does its job of restoring the wetlands and rivers of the Murray-Darling Basin to health.
But given its ambitious goals, and the diverse interests and numerous controversies that had to be mediated to get a final agreement signed into law, the Murray-Darling Basin Plan stands as an important landmark in 21st century river management.

From Stephen Garnett, Australia: Tim Flannery, in his Quarterly EssayAfter the Future, is right to deplore the sudden abrogation of responsibility for threatened species by state and federal governments. The tragedy is that neglecting endangered species is the wrong thing to do on so many counts. It does not reflect the popular will of the people. And it is counter to what is happening elsewhere in the world.
The world is taking a serious interest in saving species. And with good reason – there is increasing evidence that biodiversity loss has an influence on ecosystem service provision on a par with drought, ozone loss, acidification and climate warming. Species conservation is an investment in natural capital that provides enormous returns.
So why are Australian governments turning off threatened species? While Australia did contribute $23 million to the GEFthrough AusAid in 2011-12, here at home there is no coordinated national pool of funds for threatened species. The carbon fund and Caring for Country are lotteries in which winning tickets are too often captured by local agendas unrelated to the risk of species loss.
And the states and territories have always been poor cousins. While they have long employed threatened species managers – often deeply committed individuals who have devoted decades to retaining species for future generations – the operating money has usually had to be gleaned from a reluctant Commonwealth.
For many senior bureaucrats, Garrett’s statement was a license not to care, to make muscular decisions not to fund, supposedly on the basis that this is what the elected government wanted. I have actually attended a meeting of senior “conservation” managers in Brisbane who were only half joking when they said they would like species to go extinct because of the trouble they caused.
The real trouble is that Garrett’s statement was built on two myths.
The first is that threatened species funding does not work. Bunkum. Australia has a remarkable record of bringing animals back from the dead. All around the country there are animals and plants that were reduced to near extinction. But through thorough research, clever management coupled with diligent monitoring, and sustained commitment from both government and the local community, the small numbers have increased until extinction is now improbable.
Saving species can be expensive – small amounts smeared across many species just leads to wastage – but it works. We could abandon some species – a decision for the public not public servants to make. But for a relatively tiny amount we couldsave all of them.
Part of the perception is that the lists are not kept up to date. For instance there are 28 species or subspecies of bird on the EPBC lists that do not meet IUCN Red List criteria. Erroneously listed species waste resources and erode confidence. However the problem is with the listing process, not the efforts of threatened species managers. The conservation status of over 100 birds is better than it might have been without conservation funding. Poor administration of a clumsy Act is no excuse for abandoning threatened species.
The other myth is that people do not care. Work by Charles Darwin UniversityPhD student Gill Ainsworth shows that is wrong. In a survey designed to avoid bias, 75% said they would become upset if a bird became extinct (compared to 7% who disagreed); 74% said that people have a moral obligation to protect threatened birds (compared with 5%); and 47% said that the needs of threatened species can come ahead of people compared with 15% who thought the opposite.
There is a political opportunity here for the major parties to differentiate themselves. Though the Greens have organised a Senate inquiry into threatened species funding in Australia (submissions due 14th December), Tim Flannery is right – the Greens do not own threatened species. That is why the Australian Wildlife Conservancy is attracting corporate support. That is why many of the poorer respondents to Gill’s survey were willing to give money to threatened species protection if asked.
Ultimately of course threatened species protection is a political question. But it is also has deeper moral implications. What we do with our biological inheritance defines who we are as a people. Most countries are proud of their rare species and try to prevent extinction. For Australia our biodiversity should be seen as much a natural blessing as our mineral resources.
Coral cover in the Great Barrier Reef has dropped by more than half over the last 27 years, according to scientists, a result of increased storms, bleaching and predation by population explosions of a starfish which sucks away the coral’s nutrients.
At present rates of decline, the coral cover will halve again within a decade, though scientists said the reef could recover if the crown-of-thorns starfish can be brought under control and, longer term, global carbon dioxide emissions are reduced.
“This latest study provides compelling evidence that the cumulative impacts of storms, crown-of-thorns starfish (Cots) and two bleaching events have had a devastating effect on the reef over the last three decades,” said John Gunn, chief executive of the Australian Institute of Marine Science.
Coral reefs are an important part of the marine ecosystem as sources of food and as protection for young fish. They are under threat around the world from the effects of bleaching, due to rising ocean temperatures, and increasing acidification of the oceans, which reduces the corals’ ability to build their calcium carbonate structures.
The Great Barrier Reef is the most iconic coral reef in the world, listed as a Unesco world heritage site and the source of $A5bn (£3.2bn) a year to the Australian economy through tourism. The observations of its decline are based on more than 2,000 surveys of 214 reefs between 1985 and 2012. The results showed a decline in coral cover from 28% to 13.8% – an average of 0.53% a year and a total loss of 50.7% over the 27-year period. The study was published on Monday in the Proceedings of the National Academy of Sciences journal.
Two-thirds of the coral loss has occurred since 1998 and the rate of decline has increased in recent years, averaging around 1.45% a year since 2006. “If the trend continued, coral cover could halve again by 2022,” said Peter Doherty, a research fellow at the institute.
Tropical cyclones, predation by Cots, and bleaching accounted for 48%, 42%,and 10% of the respective estimated losses. In the past seven years the reef has been affected by six major cyclones. Cyclone Hamish, for example, ran along the reef, parallel to the coast for almost 930 miles (1,500km), leaving a trail of destruction much greater than the average cyclone, which usually crosses the reef on a path perpendicular to the coast.
The starfish problem was first recorded in 1962 at Green Island off Cairns. “When we say outbreaks, we mean explosions of Cots populations to a level where the numbers are so large that they end up eating upwards of 90% of a reef’s coral,” Gunn said. “Since 1962 there have been major outbreaks every 13-14 years.”
The evidence suggests that outbreaks of Cots start two or three years after major floods in northern rivers.
“Corals are notoriously hard to propagate in captivity and therefore the trade is still heavily dependent on harvesting from the wild.”.”
He said the results of the Great Barrier Reef survey were not surprising and the challenge for conservationists was to limit the localised threats to give reefs a chance to recover and develop resilience against the effects of climate change. “This is challenging but entirely achievable and there are many community-led projects around the world demonstrating this.”
Corals can recover if given the chance. But this is slow – in the absence of cyclones, Cots and bleaching, the Great Barrier Reef can regrow at a rate of 2.85% a year, the scientists wrote. Removing the Cots problem alone would allow coral cover to increase at 0.89% a year.
Reducing Cots means improving water quality around the rivers at the northern end of the reef to reduce agricultural run-off – high levels of nutrients flowing off the land feed and allow high survival of Cots larvae. Another option is some form of biological control of populations – Gunn said there were promising results from research on naturally occurring pathogens that could keep Cots in check, but it was not ready to be applied in the field.
He said the future of the Reef lay partly in human hands. “We can achieve better water quality, we can tackle the challenge of crown-of-thorns, and we can continue to work to ensure the resilience of the reef to climate change is enhanced. However, its future also lies with the global response to reducing carbon dioxide emissions. The coral decline revealed by this study – shocking as it is – has happened before the most severe impacts of ocean warming and acidification associated with climate change have kicked in, so we undoubtedly have more challenges ahead.”
