But Shell Australia’s Andrew Smith says onshore gas production ban will lead to price hikes for Victorian manufacturers

Australia’s gas companies have manufactured a myth that there is a gas shortage, an economist with the Institute for Energy Economics & Financial Analysis, Bruce Robertson, said.

The idea that onshore coal seam gas exploration would ease pain for manufacturers by bringing down high local gas prices in a low-price global environment “goes against basic economic theory”, he said.

The threat posed to bees by neonicotinoid pesticides is greater than perceived in 2013 when the EU adopted a partial ban, new report concludes

Europe should expand a ban on bee-harming pesticides in light of a new report warning of widespread risks to agriculture and the environment, Greenpeace has said.

The report by biologists at the University of Sussex and commissioned by Greenpeace, concluded that the threat posed to bees by neonicotinoid pesticides was greater than perceived in 2013 when the European Union adopted a partial ban.

Recordings of New Zealand yellowhammer accents enable scientists to hear how their British relatives might have sounded 150 years ago

A new study reveals that a type of native birdsong, now lost in Britain, can still be heard in New Zealand where the birds were introduced in the 19th century.

By comparing recordings of yellowhammer accents in both countries scientists were able to hear how the birds’ song might have sounded in the UK 150 years ago.

Chinese companies plan to spend $1bn building a giant solar farm on land contaminated by the nuclear disaster in Ukraine, reports Climate News Network

It was the worst nuclear accident in history, directly causing the deaths of 50 people, with at least an additional 4,000 fatalities believed to be caused by exposure to radiation.

The 1986 explosion at the Chernobyl power plant in Ukraine also resulted in vast areas of land being contaminated by nuclear fallout, with a 30-kilometre exclusion zone, which encompassed the town of Pripyat, being declared in the area round the facility.

The co-chair of parliament’s all-party cycling committee introduces its inquiry into how cyclists are treated by the police and courts

What stops more people from cycling? The answer is clear: too many people feel unsafe using Britain’s roads.

Almost two-thirds of people agree with the statement, “It is too dangerous for me to cycle on the roads.” Yet roads are too often all that people have available to them.

Sandy, Bedfordshire In the concrete underpass, chemicals leach and stain, yet here the sun can pierce blight with beauty

Two bridges cross the river, 300 metres and an aesthetic mile apart. A little downstream, 18th-century builders had carried the old Great North Road over the Ivel in the only way they knew, fashioning pretty arches from local stone and a humpbacked road wide enough for two carriages to pass.

Here, their 20th-century counterparts twinned it with something bigger. Committed to a four-lane, prosaically named A1, they used an all-prevailing material that could be relied on for strength, durability and ugliness.

Proposed plant would would be run by Kawasaki Heavy Industries and produce liquid hydrogen for use in vehicles

Victorian government plans to work with a Japanese company to produce hydrogen from brown coal in the Latrobe Valley are “a way of making brown coal look green”, according to one expert.

The proposed plant, which would be run by Kawasaki Heavy Industries as part of their Kawasaki Hydrogen Road project, would produce liquid hydrogen that would then be exported to Japan to be used in hydrogen-powered vehicles.

Cancelled flights might be your worst nightmare, but imagine a world with no flights. Flight image from www.shutterstock.com

In Australia, the amount of aviation fuel consumed per head of population has more than doubled since the 1980s. We now use, on average, 2.2 barrels (or 347 litres) of jet fuel per person per year.

This historically unprecedented aeromobility has enormous environmental costs. Aviation is contributing to around 4.9% of current global warming and this is forecast to at least triple by 2050. Domestic aviation in Australia produces around 8.6 million tonnes of greenhouse gases each year.

Offsetting schemes, technology solutions and other attempts to lower the carbon emissions of aviation have failed dismally.

The only solution to these intractable environmental impacts is the dramatic reduction, or complete elimination, of air travel. It might be hard to imagine life without the plane, but the idea is not as crazy as it sounds.

Here are nine common objections to grounding planes, and our counterpoints:

1. There are no fast, cheap and clean transport alternatives to the plane.

So we build them. We construct a national high-speed rail network and more efficient intercity, rural and urban transport systems. These projects would involve Australian steel, thousands of new jobs and large-scale regional planning and infrastructure development.

These programs would ameliorate urban congestion, the most pressing priority of Infrastructure Australia, revitalise regional communities and dramatically reduce our imports of crude and refined petroleum.

The continual development of communications technologies, including fast internet and virtual reality, will make much business travel redundant. Investing in virtual technologies and forcing the political and corporate elite to use other transport modes would hasten political support for, and investment in, the development of transport alternatives.

2. What about the economic value of tourism?

If we abandoned all tourist flights, the economy would be A$14.4 billion better off. International visitors spent A$38.1 billion in Australia in 2015-16. But, Australians travelling overseas spent far more – A$52.4 billion – in the same period.

International tourism, both in and outbound, would continue under a no–aviation scenario. As an island nation we will become reliant on ships. Travel by cruise ship is already booming. While cruise ships are currently highly polluting, their conversion to non-fossil-fuel energy, in contrast to the plane, is more achievable.

3. What about our education export industry?

Transnational education, teaching of students by Australian university offshore programs and via online distance education, is already significant, accounting for 30.2% of all higher education international students in 2015. We would invest more heavily in these educational platforms and technologies.

4. What about the jobs in the aviation industry?

Technological replacement and offshoring have decimated full-time jobs in Australia’s aviation industry. The employment generated by growth in domestic tourism and the construction of high-speed rail, ships and other transport alternatives would more than compensate.

What about the needs of farmers and hospitality industries who rely on backpackers?

We would still have a backpacker labour force under conditions of “slow tourism” that uses alternatives to cars and planes. Particularly for longer-stay tourism, arrival and departures by boat would be a small component of a trip.

We could also start using our own population for these jobs by paying higher wages. This might also reduce unemployment and dependency on social welfare and raise additional tax revenue. In the longer term we would transition to agriculture and hospitality industries that are not reliant on exploited and underpaid holiday-workers.

6. What about medical, military and rescue flights?

We need to keep essential flights for medical, rescue and firefighting purposes, and some military capacity. For essential flights, mitigation strategies like offsets may work as emissions would be low in aggregate.

7. What about sport and culture?

Sport and air travel are closely linked. Our national rugby union team is the Qantas Wallabies. Although teams travel, more spectators than ever are staying put – preferring to watch live sports on TV. Technological improvements will continue to produce a better-than-real home experience. And the eSports teams of the future may not have to leave home either.

8. Prohibition never works!

Banning things like alcohol has proven historically difficult, even in Canberra. But no-fly zones are easier to enforce – you couldn’t smuggle an A380 into the country and fly it around without anyone noticing.

9. It’s too radical a change – it would cause chaos!

Arguably, the controllable outcomes of grounding aircraft will be far less severe than the chaos of uncontrolled global climate change. A transformed, low-emissions transportation system can be planned for and, while there will be significant readjustment, life will go on.

A “business as usual” climate change scenario will unleash destruction unparalleled in human history, including the genuine threat of species extinction.

As an island nation we are more dependent than most on the aeroplane. Rather than giving us special dispensation, this puts us in a position to be world leaders in sustainable transport. Our proposal to ground planes and dramatically reduce emissions would need tremendous action in terms of civic will, and a state apparatus politically capable of taking radical action.

Liberal democracies are capable of such action, as evidenced by Australia’s Snowy Mountains Scheme. And Trump’s mandate to build infrastructure shows nation-building projects still command public support. An aviation-free Australia is a genuine and necessary alternative.

Carbon-rich peatlands in remote Congo basin could store three years’ worth of world’s fossil fuel emissions, say scientists

Scientists have discovered the world’s largest tropical peatland in the remote Congo swamps, estimated to store the equivalent of three year’s worth of the world’s total fossil fuel emissions.

Researchers mapped the Cuvette Centrale peatlands in the central Congo basin and found they cover 145,500 sq km – an area larger than England. The swamps could lock in 30bn tonnes of carbon that was previously not known to exist, making the region one of the most carbon-rich ecosystems on Earth.

Caroline Lucas criticises proposed sale to Macquarie due to Australian firm’s ‘appalling track record of asset-stripping’

Theresa May has been urged to stop the Green Investment Bank being “killed off” by a sale to private firm Macquarie, amid fears the assets will be stripped and its environmental purpose abandoned.

MPs from across the parties raised concerns about the proposed sale in the House of Commons, after Caroline Lucas, co-leader of the Green party, called a debate arguing the whole process should be stopped.

Boreholes set up by local conservationists are saving drought-stricken elephants in Hwange national park

As a drought-inducing El Niño settled over southern Africa in 2016, the animals of Hwange national park in Zimbabwe faced desperate water shortages.

During a heatwave in October, conservation worker Prince Sansole spotted an elephant partially submerged in a muddy pool. His movements initially looked no different from the water games routinely played by the giant creatures. Only a closer look revealed that the young bull was in trouble, struggling to get up. His limp trunk kept dropping back into the water, unable to catch a fresh breath.
