Campaigners hope the operation, that sees plain clothes police on bikes pull over drivers that pass too close, will be taken up across the country

When Mark Hodson gets on his bike in the morning, like many cyclists in the UK, he has come to expect a few close calls. Perhaps drivers will whizz past him too close, or someone will even try a ‘punishment pass’.

Luckily, Hodson is a West Midlands Police traffic officer, albeit in plain clothes, and just yards up the road a colleague in a police car is waiting to pull over drivers that give him less than 1.5m space when overtaking (a distance that increases for faster speeds and larger vehicles).

Flash flooding is a far greater threat to homes, railways and roads than river or coastal floods but is completely excluded from government plans to deal with increased rainfall

Flash flooding, which struck a swathe of southern and eastern England on Friday, is a greater threat to homes, roads and railways than river or coastal flooding. Yet it was completely excluded from the government’s National Flood Resilience Review, published last week.

Worse, the risk of flash flooding is rising, as climate change leads to more intense, more frequent rainstorms: the Met Office has shown that extremely wet days have become more common. On Friday, half a month’s rain was dumped in one day.

Inexpensive over-the-counter product could help millions of people avoid worst health effects of breathing toxic air, say scientists

An inhaler that protects the lungs against air pollution has been developed by scientists and could help the many millions of people affected by toxic air to avoid its worst effects.

The inhaler delivers a molecule, first found in bacteria in the Egyptian desert, which stabilises water on the surface of the lung cells to form a protective layer. It is expected to be available as an inexpensive, over-the-counter product.

‘Tremendous loss’ of ice reinforces clear downward trend towards ice-free summers due to effects of climate change

Arctic sea ice this summer shrank to its second lowest level since scientists started to monitor it by satellite, with scientists saying it is another ominous signal of global warming.

The National Snow and Ice Data Center in Colorado said the sea ice reached its summer low point on Saturday, extending 4.14m sq km (1.6m sq miles). That’s behind only the mark set in 2012, 3.39m sq km.

Paula Kahumbu: The latest satellite tracking technology is helping to keep elephants safe from poachers— and away from farmers’ crops

On a beautiful sunny day in Amboseli National Park, against the backdrop of snow-capped Mount Kilimanjaro, a small group of cars was gathered at a safe distance around the prostrate bull elephant. The elephant lay still in the dust, head on the ground, his enormous tusks and trunk stretched out in front of him. Tension rose among the onlookers as the minutes passed.

Then the huge elephant flapped his ear, got up gently, shook his head vigorously in a vain attempt to dislodge the strange object around his neck, and walked off. We all breathed a sigh of relief. The operation to attach a tracking collar to Tim had gone perfectly.

Parrtjima festival will see art beamed onto a 2.5km area of the MacDonnell Ranges, raising concerns for a struggling species

Concerns that a light festival in central Australia could affect a vulnerable population of rock wallaby has led to more than a thousand people signing a petition calling for it to be stopped, and to the federal Department of the Environment and Energy examining the festival’s plans.

Parrtjima – A Festival in Light is planned to go for 10 days at the end of September. Each night a four-hour light show will project Indigenous art onto a 2.5km stretch of cliff in the MacDonnell Ranges.

Local entrepreneur Jenny Paradiso has just been named as a finalist in the 2016 Telstra Business Women’s Awards in South Australia.

The recent battles over the budget of the Australian Renewable Energy Agency (ARENA), and before that over the size of the Renewable Energy Target, are the latest skirmishes in a long-running war over support for technologies that harvest Australia’s abundant wind and solar resources.

Perhaps surprisingly, the conflict even predates the popular awareness of climate change, which is generally dated to 1988.

UNSW Australia’s Mark Diesendorf has described how in early 1983 he and his colleagues had identified an ideal site in northern Tasmania for a wind farm. They presented their proposal to Labor’s newly appointed resources minister, Peter Walsh.

We submitted a proposal that the federal government fund a demonstration wind farm and assist in establishing a local wind generator manufacturing industry in the region, which was suffering from high unemployment. The next day, Senator Walsh announced that a northwest Tasmanian wind energy project could be a part of a development package, if the Commonwealth was successful in the High Court challenge to the construction of the Gordon-below-Franklin dam.

The Commonwealth won its High Court battle, but the wind industry did not get its windfall. As Diesendorf recalls:

The federal government did not implement our proposal. It was soon obvious that the coal lobby, which was already very strong in the Department of Resources, had succeeded in turning the minister against wind power.

At the same time, CSIRO, a world leader in several areas of renewables, closed down all of its renewable energy research. In Diesendorf’s view this was brought on by “powerful coal and nuclear energy interests within the CSIRO". In the absence of deathbed confessions by those who made the decisions, Diesendorf’s suspicions can’t be proved correct, but renewables did indeed disappear from CSIRO’s research agenda and annual reports from that time.

Once climate change hit the headlines, things changed – a little. In 1990 the Hawke government established the Energy Research and Development Corporation (ERDC) and launched a National Energy Efficiency Program. Meanwhile, research commissioned by the Victorian government found that renewable energy, paired with energy-efficiency measures, could save A$3.14 billion a year by 2005, create almost 14,000 jobs, boost economic productivity by A$800 million a year, and cut greenhouse emissions into the bargain.

But privatisation took hold in Victoria, and the Keating government in Canberra seemed indifferent at best. In 1994, green groups including the Australian Conservation Foundation called for a carbon levy to provide funds for renewable energy. Their request was ignored.

Renewables back on target

In 1996 the new Howard government disbanded Bob Hawke’s ERDC and energy efficiency program. In late 1997, in the run-up to the Kyoto climate summit, John Howard announced a new Renewable Energy Target (RET).

Greens leader Bob Brown was underwhelmed. He pointed out that the scheme’s A$65 million over five years was less than the A$75 million that had been axed the year before, while the target of an extra 2% of electricity from renewables (making a total of 11% including existing large-scale hydro electricity generation) fell short of the ambition shown by other nations. Britain, for instance, was aiming for 20% by 2010.

The RET finally came into place in 2001, after the fossil fuel lobby succeeded in getting it watered down, and was subjected to constant reviews.

Infamously, at a secret meeting whose minutes were leaked, the then energy minister, Ian MacFarlane, lamented to the chief executives of companies like BHP and Rio that the RET was working too well – renewables were growing too fast.

In the run-up to the 2004 Energy White Paper, the renewables industry had hired well-connected lobby firm Crosby Textor (yes, Crosby as in Lynton Crosby) in a bid to get the RET raised to as much as 10%.

According to Age journalist Richard Baker, a Liberal backbencher warned the renewables advocates that “you guys are stuffed". And so it came to pass – the white paper spruiked carbon capture and storage, not renewables.

In the white paper’s aftermath, CSIRO boss Geoff Garrett announced that the organisation would be reducing its renewables research and instead focusing on “clean coal” technologies such as coal gasification and carbon capture and storage.

Months later, a draft copy of an August 2005 CSIRO report describing solar thermal technology as “the only renewable technology that can make deep cuts in greenhouse emissions” was leaked to The Canberra Times. Before the leak, sources claimed the report had been “passed around like a political hot potato” with no date set for its release. It was eventually released to the public later that year.

Bloody public battles

Since 2007 the battles have been more public and even bloodier. An attempt to harmonise (and perhaps increase) different state and federal targets (all with different baselines, target years and amounts) was a dispiriting process. This was due in part, it seems, to federal bureaucratic intransigence and arrogance.

The major changes have been an increase in the renewables target, split into large-scale (wind farms, solar farms and the like) and small-scale (mostly rooftop solar). That increased target was of course subjected to significant watering down by the Abbott government.

Meanwhile, the two agencies that were set up to support renewable energy have also come under attack. The Greens, whose support was a life-and-death issue for the Gillard government, had managed to insist on the creation of ARENA and the Clean Energy Finance Corporation.

Between them, these two organisations were designed to ensure funding both for basic research and development and for commercialisation of the resulting technologies, thereby smoothing the path for renewables to enter the electricity sector.

The attacks on these organisations have helped create investor uncertainty in renewables. Efforts to close them down ultimately failed, so the Abbott government switched to changing their terms of reference. The Turnbull government has continued this, along with salami-slicing ARENA’s budget.

This investment uncertainty, deliberately created, is a kind of “divestment campaign” against renewables. It can also be seen as a way of provoking an “investment strike”.

Whereas the mining industry threatened to take its investment dollars elsewhere while fighting Kevin Rudd’s proposed Resources Super-profits Tax in 2010, in this case, the supporters of the status quo energy system are hoping to dissuade external investors from coming to Australia. Thus do incumbents defend their patch.

Australia is famously the “lucky country”. But of course, Donald Horne meant it ironically, believing that the country was richly endowed with resources but “run mainly by second-rate people who share its luck”.

Given what we know of the trajectory and probable impacts of climate change, nobody, surely, will be able to be claim surprise as the future arrives.

Stanton Moor, Derbyshire A landscape seamed with neolithic stone circles and burial sites made this one of Britain’s first official ancient monuments

There’s a dog-eared feel to Stanton Moor, but in a good way. It’s a much loved scrap of high country between Bakewell and Matlock, sacred ground in the neolithic and bronze ages, its geomantic potency derived from long views and its proximity to the confluence of the rivers Derwent and Wye. And it’s fairly sacred even now, after a fashion.

The Earth’s last intact wilderness areas are shrinking dramatically. In a recently published paper we showed that the world has lost 3.3 million square kilometres of wilderness (around 10% of the total wilderness area) since 1993. Hardest hit were South America, which has experienced a 30% wilderness loss, and Africa, which has lost 14%.

These areas are the final strongholds for endangered biodiversity. They are also essential for sustaining complex ecosystem processes at a regional and planetary scale. Finally, wilderness areas are home to, and provide livelihoods for, indigenous peoples, including many of the world’s most politically and economically marginalised communities.

James Watson and James Allan explain their recent research.

But there’s another important service that many wilderness areas provide: they store vast amounts of carbon. If we’re to meet our international climate commitments, it is essential that we preserve these vital areas.

Many of the world’s biological realms now contain very low levels of wilderness. www.greenfiresciene.com Climate consequences

Large, intact ecosystems store more terrestrial carbon than disturbed and degraded ones. They are also far more resilient to disturbances such as rapid climate change and fire.

For instance, the boreal forest remains the largest ecosystem undisturbed by humans. It stores roughly a third of the world’s terrestrial carbon.

Yet this globally significant wilderness area is increasingly threatened by forestry, oil and gas exploration, human-lit fires and climate change. These collectively threaten a biome-wide depletion of its carbon stocks, considerably worsening global warming. Our research shows that more than 320,000sqkm of boreal forest has been lost in the past two decades.

Similarly, in Borneo and Sumatra in 1997, human-lit fires razed recently logged forests that housed large carbon stores. This released billions of tonnes of carbon, which some estimate was equivalent to 40% of annual global emissions from fossil fuels. We found that more than 30% of tropical forest wilderness was lost since the early 1990s, with only 270,000sqkm left on the planet.

All nations need to step up and mobilise conservation investments that can help protect vanishing wilderness areas. These efforts will vary based on the specific circumstances of different nations. But there is a clear priority everywhere to focus on halting current threats – including road expansion, destructive mining, unsustainable forestry and large-scale agriculture – and enforcing existing legal frameworks.

For example, most of the world’s remaining tropical rainforests are under an onslaught of development pressures. Much of sub-Saharan Africa is being opened up by over 50,000km of planned “development corridors” that criss-cross the continent. These will slice deep into remaining wild places.

In the Amazon, plans are being made to construct more than 300 large hydroelectric dams across the basin. Each dam will require networks of new roads for dam and powerline construction and maintenance.

In northern Australia, schemes are afoot to transform the largest savannah on Earth into a food bowl, jeopardising its extensive carbon stores and biodiversity.

We need to enforce existing regulatory frameworks aimed at protecting imperilled species and ecosystems. We also need to develop new conservation policies that provide land stewards with incentives to protect intact ecosystems. These must be implemented at a large scale.

For example, conservation interventions in and around imperilled wilderness landscapes should include creating large protected areas, establishing mega-corridors between those protected areas, and enabling indigenous communities to establish community conservation reserves.

In Sabah, Borneo, scientists from the UK’s Royal Society have been working with local government to establish networks of interlinked reserves stretching from the coast to the interior mountains. This provides a haven for wildlife that migrate seasonally to find new food sources.

Funding could also be used to establish ecosystem projects that recognise the direct and indirect economic values that intact landscapes supply. These include providing a secure source of fresh water, reducing disaster risks and storing vast quantities of carbon.

For example, in Ecuador and Costa Rica, cloud forests are being protected to provide cities below with a year-round source of clean water. In Madagascar, carbon funding is saving one of the most biodiversity-rich tropical forests on the planet, the Makira forest.

We argue for immediate, proactive action to protect the world’s remaining wilderness areas, because the alarming loss of these lands results in significant and irreversible harm for nature and humans. Protecting the world’s last wild places is a cost-effective conservation investment and the only way to ensure that some semblance of intact nature survives for the benefit of future generations.

Regulator report into SA high price event shows generators have a new way to exploit their market power, underling the case for rule changes.

Solar storage developer says it would be a shame if Australian authorities "doubled down" on gas, and missed the opportunity to introduce new technologies that could lower prices, boost jobs, and accelerate clean energy transition.

According to the Victorian pricing authority – yes they are. But is this a “market failure” that justifies regulatory intervention, or are we missing something?
