Australia's carbon tax is a brave start by a government still gripped by fear

Labor's climate change measures – modest, riddled with exclusions, bribing voters and corporations – are a beginning

Australia's Black Saturday fires of February 2009 burned over a million acres of land and killed 173 people. It happened because of record high temperatures and an exceptionally dry summer. It was what climate experts had been predicting for some years: the megafire. A megafire is hell come to earth.

The energy equivalent to 1,500 Hiroshima-sized atomic bombs was released in a fire storm that saw rivers of flame – sometimes rising 100 metres in the air – flowing through the countryside, generating winds of up to 120km an hour with new fires spotlighting 35km ahead of the main fire front.

Black Saturday reminded many Australians of what they know only too well: that of all the advanced economies, Australia is perhaps the one most vulnerable to climate change. And yet support for action on climate change, which was a key factor in the ending of 11 years of conservative government in 2007, has now largely collapsed.

In a story of ironies, a Labor government rarely characterised in recent times by either vision or courage has just announced a raft of measures, centred on a carbon tax, to reduce Australia's carbon emissions, an act at once brave and visionary. It was, though, forced on them by others.

It has been the strangest of battles that has already claimed two opposition leaders and one prime minister. And depending on who wins it, the rictus smile of Australian public life – behind which has hidden for years a paralysis of thought and action and has seen the coal and iron ore barons, the shock jocks and the Murdoch press seeming to set the political agenda as much as parliament – will continue or begin to break.

A conservative opposition leader, Tony Abbott, who once said climate change is "crap" and yet who is on record some years ago offering the most eloquent defence that could be made for a carbon tax, has waged a highly brutal – and effective – campaign against just such a tax by creating the impression that the Australian way of life will end if it comes to pass. His attempts to create a Tea Party-type fervour in support of his position has created an atmosphere in which serious climate scientists are receivingdeath threats and Lord Moncktonis taken seriously. If elected – and polling has him well placed to win the next election – he has promised to repeal the carbon tax.

A Labor prime minister, Julia Gillard, who does believe in climate change, nevertheless advised her predecessor, Kevin Rudd, to abandon his emissions trading scheme. In consequence, Rudd's electoral support vanished and he was replaced a few months later by the same Julia Gillard who promptly went to an election promising no carbon tax.

That there is to be any action at all is to the credit of the Greens, who won the balance of power in the Australian senate in that election and made the carbon tax the condition of their support for Gillard's minority Labor party. But the package of measures now announced are far from what the Greens argue is necessary to combat climate change by a nation which in spite of its small (22 million) population is one of the world's top 20 carbon polluters.

Perhaps it could not be otherwise. Australia has avoided recession because of its resource industries. Unemployment is just over 5%. The coal, iron and gas barons combine massive wealth with a certain psychological dominance – without us, where would Australia be? – which is implicit in all their public posturing and pressurising. They interpret national interest as their profit and loss ledger and that, they regard, along with their successful bullying of public life, as being under attack from a carbon tax.

Along with Abbott's Liberals, they are keenly aware of Labor's tenuous hold on power. Gillard's minority government survives on just a one-seat margin and is languishing in the polls at 27%. Whoever wins the carbon tax battle wins government at the next election.

Gillard, on her side, has to placate her coalition of Greens and independent rural MPs, soothe an electorate worried about cost of living increases, and throw enough protection money at the big resource companies to stop them fully setting their dogs on her. The measures thus contain a large reform of tax in favour of the poor and large subsidies to big business to compensate for reduced profits. Her dilemma is that the only package she can get up in consequence is one that fails to deliver the very change that is needed.

And so, though designed with mechanisms for increasing decarbonisation, the tax begins life as modest in its impact, riddled with compromises, exclusions, bribes to both voters and corporations, a low carbon price of $23 (£15) a tonne and a very low carbon emission reduction target of 5% by 2020 – about half that required to stabilise carbon emissions at 550 parts per million (ppm), if other countries take comparable action.

The government's own climate change adviser, Ross Garnaut, hascalculated that halting the growth in emissions at 550ppm-650ppm would lead to an average temperature rise of 3C to 4C – a rise with disastrous implications for Australia. Selling such a convoluted raft of measures is difficult: former Labor prime minister Bob Hawke has compared it to making "ice cream out of a bucket of shit''.

And selling it is a prime minister with the speech and appearance of a dying metronome – she is so inept it has been said she couldn't sell the wheel – dragging along behind her a Labor party that must now present the measure Labor didn't want as Labor's achievement.

It may be that the carbon tax is the final chapter in the strange death of Labor Australia. A once great reforming tradition is now too often the captive of fears and dogmas generated in the service of corporate Australia; under attack from the right by an able populist leader, who has never been burdened by the need for consistency or coherence, and rarely challenged on either; and from the left by the increasingly popular Green party.

Many arguments are already being made against the tax. The best argument that can be made for it is that, like all great reforms, it is a historic beginning. And perhaps it is the hope implicit in the carbon tax that is its most important feature.

Among many other reforms, Australians pioneered the secret ballot, universal suffrage and rape in marriage legislation. Whether Australia still has the courage it once had, or whether it has simply become the United Arab Emirates of the west, content to roll on for a decade or two more glossing over its fundamental problems while brown coal and fracked gas continues to keep the country afloat, remains to be seen.

The carbon tax thus looms over Australia as a large question: does Australia have the desire to move into the 21st century, or will it continue its retreat into a past as a colonial quarry for the empires of others, its public life ever more run at the dictate of large corporations, its people ever more fearful of the megafires of the future?

french ken knows where it aint

somebody who once knew you
bought the pad of the week
in the deal of the century
it was just a hop, step and a tram down st kilda rd
in a lovely park
a large open space
but not any park on st kilda boulevard that you know
i went to check it out
this abode to be
it was once only a cave or a cavern and white all around
white as the fabled city of Minas Tirith
but nowhere near as presumptuous
but the lady that scored it
in some shady undercloak dealings
found a hitherto undiscovered handyperson skills
with only a blowtorch
she turned this caverna arrangement
into a 2 or 3ish bedroom pad
perhaps it was a study
or perhaps it was just walls of clothes
ones a child could disappear into
or a studio
it seemed to morph before thine very eyes
with said blowtorch
she created cathedral white ceilings
a living room
some rather skinny doors
but the masterblaster bedroom kept an odd feature
a perilous looking circular spike of a stump of the wisp
'might have to do something about that later'
the natural light was coming from skylights which were just glass rectangles amidst the lush green grass
of home
i did wonder out loud
but what about the hooligans?
might they not break or defecate on the windows?
a fence would be impractical
this is a public park after all
and somebodies would be sharing this marvellous adobe abode with a fine upstanding chap
who goes by the name of French Ken
No friend of mine
No acquaintance of of Killer
but apparently he's all the rage
they assured us he's not related to Sad Ken
who never won that race
French Ken may well become a pivotal character in this unfolding unreal world...

because fishy is worth it...

Coelacanth slowly reveals its secrets

An odd-looking ancient fleshy fish continues to serve as a reminder of just how little we know about the natural world.

In 1938, scientists discovered the coelacanth, a large primitive deep-dwelling fish that was supposed to have been long, long extinct.

The fish provided an immediate link to our dim evolutionary past, resembling the lobe-fin fishthat were likely the first to leave the water and take to land, ultimately begetting the amphibians, reptiles and mammals we see today, including the human race.

The fish’s discovery was a worldwide sensation, and the coelacanth remains famous to this day, its name synonymous with the concept of living fossils and great natural history discoveries.

But new research just published reveals, in its own way, just how little we still know about this fish, despite it being the subject of intensive scrutiny and excitement for more than 70 years.

A team of scientists based in France and Germany has just summarised the results of a 21 year study into coelacanths living in the Comoros Islands, in the western Indian Ocean.

That in itself is impressive.

After its initial discovery in South African waters, another was not sighted by western scientists until fourteen years later, when a few fish were found swimming off the Comoros. The fish was not filmed alive until the BBC serendipitously took some footage of one for the programme Life on Earth broadcast in 1979 (see video below) and the first photos of the fish in its natural habitat were not taken until 1988.

So considering how enigmatic the coelacanth has been, it is remarkable that we now have a population study of the fish lasting more than two decades.

The study was done on Latimeria chalumnae by Hans Fricke of the Max Planck Institute for Marine Microbiology in Bremen, Germany and colleagues.

Latimeria chalumnae is a deep blue fish that has been sighted around Africa, off the coasts of South Africa, Mozambique, Kenya, Tanzania and Madagascar. It is one of two species of coelacanth; the other, Latimeria menadoensis, is a brown fish found much more recently in Indonesia.

The scientists used remote operated vehicles to descend into the sea and survey an 8km-long stretch of coastline around Grand Comore inhabited by coelacanths. The ROVs followed the fish into the caves in which they live, filming and photographing individuals, which are recognisable by the pattern of white spots on their blue bodies.

They have made some wonderful discoveries.

Coelacanths, it seems, are peaceful animals that do not act antagonistically to one another, even when groups of up to 16 fish share the same cave.

Females are markedly larger than males but there doesn’t appear to be any sexual content to their gatherings.

During the day, the fish live at a depth of 170-240m along a steep volcanic landscape of caves, and at night they drift down to depths of 500m to feed, coming back to their caves in the morning to rest.

The survey reinforces the impression that perhaps just 300-400 coelacanths live at Grand Comore and that the fish do not tolerate waters above 22 degrees Centigrade particularly well, as many fish disappeared from the study area in 1994 when the water warmed, returning later.

The study demonstrates how much our understanding of these wonderful fish has improved in the past few decades.

Other research in this time has shown that coelacanth embryos develop for three years, the longest recorded for any vertebrate.

Coelacanths also appear to have the lowest metabolic rates among vertebrates.

But the study by Fricke’s team, published in this month’s issue of Marine Biology, also gives away how much more we still don’t know.

For example, during the entire survey period, the team did not record a single subadult, juvenile, or baby coelacanth. They didn’t spot one in the Comoros, and have never spotted one in separate expeditions to study the fish off Indonesia, South Africa or Tanzania.

Only a single baby coelacanth has ever been sighted, filmed by different researchers in 2009 at a depth of 160m.

So we do not know where coelacanths give birth, where the young go, or why they don’t live with the adults. Such information is vital to preserve species of such rarity.

We still have little idea about how long these ancient-looking fish live for.

The survey by Fricke’s team confirms that coelacanths can live for at least 21 years; they resighted the same fish at the start and end of the survey, while 17 fish were sighted 19 years apart. That confirms that it is unexceptional for a coelacanth to live for two decades at least – the first real evidence of a coelacanth’s minimum age.

The scientists’ survey also allowed them to calculate the mortality rate of the fish, based on how often the same fish were resighted over the following years.

Their best estimate is that coelacanths have a mortality rate of 0.044. That means that out of a cohort of 100 individuals, we would expect one to still be living 103 years later. Their data can be used to make another mathematical projection which suggests coelacanths can live for between 95 to 117 years old.

Other deep water fish have been found to live for around 100 years, so it’s plausible that coelacanths do indeed reach this epic age. But we still don't know for sure, nor what their average age might be.

One bit of positive news is that accidental catches of coelacanths around the Comoros are declining steeply.

Fishermen in the area used to fish using a long line and hook from motorless canoes called galawas, and would occasionally snare a coelacanth while fishing at night for oilfish.

Nowadays, the fishermen use motorized boats called vedettes to travel further out to sea – mostly avoiding the coelacanth’s habitat. Between 1954 and 1995 two to four coelacanths were taken each year. But after 2000, that has fallen to just 0.3 coelacanths on average.

These fishermen are the only known cause of mortality for coelacanths; Fricke’s team’s survey occasionally encountered large sand tiger sharks in the area but never witnessed any predation on coelacanths by larger fishes.

As ever, though, with extremely rare species, threats to their very existence never seem far away.

In Tanzania, another home to coelacanths, fishermen once took edible small fish from shallow waters. But once these were wiped out, they took to using deep-water gill nets. Since 2003, when these nets were first used, more than 80 coelacanths have been caught, and the number is increasing each year.

That is of huge concern for this population of Latimeria and it also reinforces how similar might happen around the Comoros, one of the fish’s remaining known strongholds.

One answer, if it can be arranged with the people of the Comoros, is to set aside a protected area along the south-west coast of Grand Comore, a policy supported by Fricke’s team and other researchers.

We still know so little about this ancient fish. And perhaps we owe it: having thought it extinct for so long, it might be considered tragic to let it go extinct now.

This is a fish that has survived almost unaltered for millions of years. Yet we risk it becoming extinct in just a handful of years due to subtle shifts in the way we choose to fish, and treat our marine life.

If it does disappear, it will go long before we've had a chance to truly understand it.
