Readers of RenewEconomy may find access to the website unexpectedly slow or difficult today, because of measures it introduced to deal with repeated denial of service attacks.

The story behind a small ivory sculpture that was carved 40,000 years ago.

It is difficult not to lapse into despair about Australia’s energy policy morass, which is dominated by a deeply entrenched culture of half-truths, vested interests, ideology and wishful thinking.

Once again, California is leading the way, this time on state contracts for infrastructure, where suppliers work to keep their carbon pollution low.

Nicaragua signs the Paris agreement, leaving only two countries not supporting it.

New Zealanders were urged to 'vote kea' in a video campaign for the world's only alpine parrot, resulting in thousands more votes cast for the species than ​actual birds in existence. The nation's annual bird of the year competition hit new heights this year with more than 50,000 votes cast from around New Zealand and the world. Despite their protected status, keas have divided Kiwis between those who enjoy the cheeky parrot’s animated nature and those who curse its destructive habits

Vice-president Rosario Murillo calls global pact ‘the only instrument we have’ to address climate change as number of outsiders shrinks to two

Nicaragua is set to join the Paris climate agreement, according to an official statement and comments from the vice-president, Rosario Murillo, on Monday, in a move that leaves the United States and Syria as the only countries outside the global pact.

Nicaragua has already presented the relevant documents at the United Nations, Murillo, who is also first lady, said on local radio on Monday.

The world’s only mountain parrot whose cheeky antics divide Kiwis, beats kererū and kākāpō to coveted crown

• New Zealand bird of the year leaderboard: check the pecking order

The kea, the world’s only alpine parrot, has been crowned New Zealand bird of the year, with thousands more votes cast for the species than there are surviving individuals.

New Zealand’s annual bird of the year competition hit new heights this year with more than 50,000 votes cast from around the country and the world. The competition is in its 13th year, and pits the country’s rare and endangered birds against one another. No bird has won twice.

Last week, a parable of Australia’s energy policy chaos came to light. Not in the bawdy policy debate in Canberra, but in the quietly filed financial reports of a power station owner.

Photographer Tim Flach’s latest book Endangered, with text by zoologist Jonathan Baillie, offers a powerful visual record of threatened animals and ecosystems facing the harshest of challenges

Tim Flach sees his Hasselblad H4D-60 camera as a means to its end: capturing the character and emotions of an animal. Until now his interest has been in the way humans shape animals, but in his new book, Endangered, he poses the question of what these animals, and their potential disappearance, mean to us.

Twenty months of shooting and six months of assembling has resulted in a collection of more than 180 pictures. “In some cases we put up a black background in a zoo or a natural reserve, in others it meant being underwater with hippos or great white sharks.”

Scientists were expected to report that climate change is affecting air and water temperatures, precipitation, sea level and fish in New England’s largest estuary

The Environmental Protection Agency kept three scientists from speaking at a Rhode Island event about a report that deals in part with climate change.

The scientists were expected to discuss in Providence on Monday a report on the health of Narragansett Bay, New England’s largest estuary. The EPA did not explain exactly why the scientists were told not to.

Plastic pollution, overfishing, global warming and increased acidification from burning fossil fuels means oceans are increasingly hostile to marine life

If the outlook for marine life was already looking bleak – torrents of plastic that can suffocate and starve fish, overfishing, diverse forms of human pollution that create dead zones, the effects of global warming which is bleaching coral reefs and threatening coldwater species – another threat is quietly adding to the toxic soup.

Ocean acidification is progressing rapidly around the world, new research has found, and its combination with the other threats to marine life is proving deadly. Many organisms that could withstand a certain amount of acidification are at risk of losing this adaptive ability owing to pollution from plastics, and the extra stress from global warming.

Exclusive: Freedom of information request reveals ‘disgraceful’ amount of taxpayers’ money used to battle ClientEarth over illegally poor air pollution plans

The government spent £370,000 of taxpayers’ money unsuccessfully fighting court claims that its plans to tackle air pollution were illegally poor, a freedom of information request has revealed.

The money was spent battling two actions brought by environmental lawyers ClientEarth and included more than £90,000 in costs paid to the group after it won on both occasions. Critics said the government’s expenditure was “disgraceful” and should have been spent on cutting pollution.

From today the most polluting vehicles on London roads will face a ‘toxicity’ fee. It’s a vital first step towards cleaning up the UK’s dangerously dirty air

A report released last week by international experts shows pollution to have caused more deaths in the UK than in many other countries in western Europe. Air pollution is largely invisible, so it is hard to grasp how much damage it is doing to our health. But studies like the Lancet commission on pollution make it clear that poor air quality increases not only the likelihood of developing a range of respiratory illnesses, but also the frequency and severity of bouts of those illnesses.

Like many GPs, I see this “double hit” in the children and adolescents who come to surgery every day. Preschool children who live near main roads have an increased risk of developing wheeze triggered by viral colds – a condition we call “preschool wheeze”. Exposure to traffic pollution also increases the chance of a child developing asthma. For preschool wheezers and children with asthma, high pollution days can then trigger episodes of severe wheezing, especially when pollution has not been dispersed by the wind.

British Beekeepers Association survey reveals worrying drop in honey yield, with 62% of beekeepers saying neonicotinoids are to blame

Beekeepers have raised concerns over the future of honeybees as an annual survey showed a “steady decline” in the honey crop.

The survey by the British Beekeepers Association (BBKA) revealed beekeepers in England produced an average of 11.8kg (26 lb) of honey per hive this year, down 1kg on last year.
