Geodynamics makes announcement as solar researchers speak out against cuts to the Australian Renewable Energy Agency

Renewable energy projects in Australia are already being suspended as a result of the two major parties’ plans to effectively abolish the Australian Renewable Energy Agency (Arena).

In an announcement this week to the Australian Stock Exchange, Geodynamics announced it was suspending two large biogas projects in Goulburn, New South Wales, and Mindarra, Western Australia. It told investors it was doing so because of uncertainty surrounding the possibility of getting grant funding for the projects in the future.

Kit Hill, Tamar Valley Patches of sunlight enhance emerald regrowth in hay and silage fields, and the luminous glow of stubble and uncut corn

Harvesting of cereals is fast these days, hardly noticed by passersby. Close to home, stubble is glimpsed through gateways off narrow lanes encompassed by rank hedge banks overgrown with honeysuckle. Loaders and trailers race to gather the big round straw bales before rain, and there remain some uncut fields of later, spring-sown, barley.

The rare sight of stooks (cut for thatching) prompt boyhood reminiscences: Jack, my husband, drove the Fordson Major, pulling the binder with his father sitting on the back, and our neighbour, Jeff from Yorkshire, was tasked with catching tossed up sheaves and handing them, butt side out, to the expert rick builder for layering around the central vent.

Craig Kelly says he wants wind and solar funding to be redirected to research into ‘technological breakthroughs’ because existing renewables had ‘little effect’

The Liberal chairman of the Coalition’s environment policy committee, Craig Kelly, has questioned solar and wind power subsidies and would like a cost-benefit analysis of future emission reductions policy, due to be reviewed next year.

Kelly was named chairman of the environment and energy committee at the party room meeting on Monday, making him responsible for coordinating backbench feedback to the government on climate and energy policy.

Iranian Cheetah Society says situation is critical as numbers of the subspecies continue to dwindle

Conservationists say only two female Asiatic cheetahs are known to be alive in the wild in Iran, which hosts the last surviving population.

Asiatic cheetahs, also known as Iranian cheetahs, are a subspecies of the fastest animal on earth and classified as critically endangered, with fewer than 40 believed to remain in Iran.

Several manufacturers have launched models that produce more pollutants when driven in real-world conditions

New diesel cars are still emitting many times the official limit for polluting nitrogen oxides when driven on the road, almost a year after the Volkswagen emissions scandal broke.

Renault, Mercedes-Benz, Mazda and Hyundai have all launched diesel models in 2016 with NOx emissions that are far higher than the official lab-based test when driven in real-world conditions, according to tests by Emissions Analytics (EA), a company whose data is used by the manufacturers of most cars sold in Europe.

With the planet at a crossroads, September will bring two crucial global conferences on the urgent issue of how best to protect endangered species

Consumers and collectors want sturgeon caviar, snakeskin bags, shark meat and fins, wild snowdrop bulbs, precious rosewood furniture, and quality agarwood oil, as well as rare birds, reptiles, cacti and orchids. But they rarely stop to think about their origins. There are now over seven billion people consuming biodiversity every day in the form of medicines, food, clothing, furniture, perfumes and luxury goods. Demand for products drawn from nature is increasing, and with it pressure is growing on some of our wildlife species.

Our capacity to harvest from the wild has no limits, and modern transport has no frontiers. There are 1.1 billion international tourist arrive a year, 100,000 flights every day, and 500 million containers are shipped a year, allowing wildlife products to reach the four corners of the earth, legally or illegally. The tensions between boosting global trade, promoting development and conserving wildlife persist, in what sometimes seems like a set of objectives that are pulling in opposite directions.

Report was expected in July and concerns have been raised that there will not be time to implement recommendations before winter

MPs and council leaders have written to Theresa May seeking assurances after a delay in the publication of a government report on the UK’s flood defences.

The national flood resilience review was established to assess how the country can be better protected from flooding and increasingly extreme weather events, and its report had been expected in July.

A report launched on 3 August by Unesco’s World Heritage Centre and International Union for Conservation of Nature (IUCN) explores the importance of marine life in the open ocean, which covers more than half the planet

Records of temperature that go back far further than 1800s suggest warming of recent decades is out of step with any period over the past millennium

The planet is warming at a pace not experienced within the past 1,000 years, at least, making it “very unlikely” that the world will stay within a crucial temperature limit agreed by nations just last year, according to Nasa’s top climate scientist.

This year has already seen scorching heat around the world, with the average global temperature peaking at 1.38C above levels experienced in the 19th century, perilously close to the 1.5C limit agreed in the landmark Paris climate accord. July was the warmest month since modern record keeping began in 1880, with each month since October 2015 setting a new high mark for heat.

Aviva, Aegon and Amlin issue joint statement urging leaders to build on previous commitments and end subsidies within four years, reports Climate Home

Three of the world’s biggest insurers have called on G20 leaders to implement a timeframe for ending fossil fuel subsidies when they meet in China this week.

The G20 has already committed to phase out “inefficient fossil fuel subsidies that encourage wasteful consumption” over the “medium term”. In May, the G7 nations pledged to achieve this by 2025.

Ten areas now licensed for culling, with Herefordshire, Cornwall and Devon added to Gloucestershire, Somerset and Dorset

The number of areas where badgers will be culled to stop the spread of bovine tuberculosis is to more than triple under licences issued by the government on Tuesday.

Licensed shooters could begin killing badgers within days in Herefordshire, Cornwall and Devon, which have been added to the culling already taking place in recent years in Gloucestershire, Somerset and Dorset.

Small-scale fishers hope technology will convince ministers that there are enough stocks to feed communities sustainably

A smartphone app that logs data on fish catches is giving small-scale fishers in South Africa hope they can persuade the government to allocate them more of what they regard as their traditional fishing rights.

Abalobi, the app which is named for the isiXhosa phrase abalobi bentlanzi, meaning “someone who fishes”, aims to give small-scale fishers the data to empower themselves and convince others.

Academics say planners are concentrating on reducing road deaths and promoting growth at expense of environment

There has been little improvement in air quality over the past 20 years as transport planners focus on preventing road deaths, according to a study.

Two university academics set out to try to understand why there has been little improvement in air pollution concentrations from road transport since the UK signed up to international air quality standards in 1995, as part of the Environment Act.

Rutland Water, Rutland Ram’s-horns are very successful animals and are found in just about every permanent still water body in the UK

Secluded by sallow bushes and clumps of great willow herb is a small pond. In the natural surroundings it looks a little contrived, being a raised wooden structure, bench height and pentagonal. Nevertheless it provides a quiet haven after a day of solid talking at the British bird fair.

The heavy warm air is now cooling and the clouds darkening. With casual curiosity I lift a white water-lily leaf the size of a dinner plate from the pond surface and peer underneath. Adhering to the underside, looking like a dark brown shirt button, is a tight coil of a ram’s-horn snail.

Activists and farmers hail decision after inquiry into onshore unconventional gas received 1,600 submissions

Victoria is to introduce a permanent ban on all onshore unconventional gas exploration, including fracking and coal seam gas, becoming the first Australian state to do so.

The premier, Daniel Andrews, made the announcement on Tuesday morning and said legislation for the ban would be introduced later this year, making the current moratorium on unconventional gas exploration permanent.

There is a battle under way near Cannon Ball, North Dakota, over plans for a multibillion-dollar oil pipeline. The North Dakota Access pipeline will run just outside the formal boundary of the Standing Rock Sioux reservation, and tribal members fear it will pollute local drinking water and disturb sacred sites

The darkest prognosis is that bio, cyber or environmental catastrophes could foreclose humanity’s potential. But there is an optimistic option

On Christmas Eve 1968, the Apollo 8 astronaut William Anders took a photograph of the view outside the window as his spaceship orbited the moon. The now iconic Earthrise image shows our half-moon blue planet under a decoration of clouds rising from the blackness of space over the lunar surface.

The picture encapsulated Earth’s precariousness in the cosmos and, for many, contained a message of humility and stewardship for our home.

Experts say human impact on Earth so profound that Holocene must give way to epoch defined by nuclear tests, plastic pollution and domesticated chicken

Humanity’s impact on the Earth is now so profound that a new geological epoch – the Anthropocene – needs to be declared, according to an official expert group who presented the recommendation to the International Geological Congress in Cape Town on Monday.

The new epoch should begin about 1950, the experts said, and was likely to be defined by the radioactive elements dispersed across the planet by nuclear bomb tests, although an array of other signals, including plastic pollution, soot from power stations, concrete, and even the bones left by the global proliferation of the domestic chicken were now under consideration.

Nova Innovation deploys first fully operational array of tidal power turbines in the Bluemull Sound

A power company in Shetland has claimed a breakthrough in the race to develop viable offshore tidal stations after successfully feeding electricity to local homes.

Nova Innovation said it had deployed the world’s first fully operational array of tidal power turbines in the Bluemull Sound between the islands of Unst and Yell in the north of Shetland, where the North Sea meets the Atlantic.
