Half of world's rare antelope population died within weeks
Scientists are struggling to explain the mass die-off of at least 150,000 endangered saiga antelopes in Kazakhstan earlier this year
More than half of the world’s population of an endangered antelope died within two weeks earlier this year, in a phenomenon that scientists are unable to explain.

The city’s toxic air has been linked to allergies, respiratory conditions, birth malformations and increasing incidence of cancers. But as a recent car-free experiment showed, action to cut pollution can be effective
For a few hours one morning two weeks ago, private cars were banned from driving into the heart of old Delhi. It was hard to tell at the messy road junction in front of the historic Red Fort and the shopping street of Chandni Chowk, though, which was still crammed with auto-rickshaws and buses barrelling along the roads with seemingly little regard for any traffic rules.
But Delhi’s so-called “car-free day” experiment was nevertheless a success: scientists monitoring the air here, routinely one of Delhi’s most polluted areas, found a dramatic 60% drop in the amount of dangerous pollutants – the tiniest particles that come out of traffic exhausts and which can exacerbate health problems such as asthma, heart disease and stroke – compared to the previous day.

Genetically modified ash trees could replace the 80 million expected to die in the next 20 years from a deadly fungus, scientists have proposed.
The radical solution to the greatest woodland disaster of the last 50 years is being explored by research teams at London and Oxford universities with backing from the Department for Environment, Food and Rural Affairs, science bodies and the Forestry Commission.

The Atacama desert is experiencing a rare springtime bloom of flowers after El Niño brought the heaviest rainfall in two decades earlier this year. The desert is usually one of the driest places on Earth. Flowers normally bloom every five to seven years but this year’s showing has been one of the most spectacular

Waters in the north-west Atlantic have warmed 99% faster than the rest of the world’s oceans in the past decade due to changes in the Gulf Stream and Pacific
A rapid warming of the Gulf of Maine off the eastern United States has made the water too warm for cod, pushing stocks towards collapse despite deep reductions in the number of fish caught, a US study has shown.

Consensus builds among scientists though review of evidence also finds there is not enough data on whether pesticide causes population decline
There is a strong scientific consensus that bees are exposed to neonicotinoid pesticides in fields and suffer harm from the doses received, according to a new analysis of the all the scientific evidence to date.
But almost no data exists so far on whether this harm ultimately leads to falls in overall bee populations, the scientists found. They said one “gold standard” field study from Sweden had shown that the insecticides, the most widely used in the world, do significantly damage bumblebee populations. But it found no effect for honeybees, although the study design meant it could only rule out losses greater than 20%.

Oil heartlands of Abu Dhabi, Dubai, Doha and Iran’s coast will experience higher temperatures and humidity than ever before on Earth if the world fails to cut carbon emissions
The Gulf in the Middle East, the heartland of the global oil industry, will suffer heatwaves beyond the limit of human survival if climate change is unchecked, according to a new scientific study.
The extreme heatwaves will affect Abu Dhabi, Dubai, Doha and coastal cities in Iran as well as posing a deadly threat to millions of Hajj pilgrims in Saudi Arabia, when the religious festival falls in the summer. The study shows the extreme heatwaves, more intense than anything ever experienced on Earth, would kick in after 2070 and that the hottest days of today would by then be a near-daily occurrence.

Fires have spread beyond plantations deep into primary forests and national parks, the last strongholds of the endangered apes
Raging Indonesian forest fires have advanced into dense forest on Borneo and now threaten one third of the world’s remaining wild orangutans, say conservationists.
Satellite photography shows that around 100,000 fires have burned in Indonesia’s carbon-rich peatlands since July. But instead of being mostly confined to farmland and plantations, as they are in most years, several thousand fires have now penetrated deep into primary forests and national parks, the strongholds of the remaining wild apes and other endangered animals.
Morocco poised to become a solar superpower with launch of desert mega-project
World’s largest concentrated solar power plant, powered by the Saharan sun, set to help renewables provide almost half the country’s energy by 2020
- Read this story in French
The Moroccan city of Ouarzazate is used to big productions. On the edge of the Sahara desert and the centre of the north African country’s “Ouallywood” film industry it has played host to big-budget location shots in Lawrence of Arabia, The Mummy, The Living Daylights and even Game of Thrones.
Now the trading city, nicknamed the “door of the desert”, is the centre for another blockbuster – a complex of four linked solar mega-plants that, alongside hydro and wind, will help provide nearly half of Morocco’s electricity from renewables by 2020 with, it is hoped, some spare to export to Europe. The project is a key plank in Morocco’s ambitions to use its untapped deserts to become a global solar superpower.

Three young squid caught by marine biologists are the spitting image of their gigantic parents – if nearly 1,000lbs and 50ft smaller
Marine biologists have captured three young giant squid, Japanese researchers reported, in what would be the first confirmed catch of very young juveniles of the elusive creature.
The young squid, caught off south-western Japan, are replicas of their gigantic parents who live in the deep. Two were caught together; all three weighed less than 1lb and spanned 5-13ins. Adults can reach 50ft and 1,000lbs.

Announcement to create largest area of national park land in England welcomed by campaigners after two-year wait for decision
Two of England’s most celebrated national parks, the Yorkshire Dales and the Lake District, are being extended, the government has announced.
The Yorkshire Dales national park will expand by almost 24% and the Lake District national park by 3%, creating a large and almost continuous protected area in north-west England.

Liberals took up a progressive mantle when the NDP failed to project a vision of environmental and social justice – now it’s up to the public to bend them to their will
On Monday night many Canadians breathed out a sigh of relief. Then they breathed in a whiff of apprehension. The ousting of the Conservatives was a victory, a rejection of Stephen Harper’s politics of fear and racism. But Canadians now confront a Prime Minister gifted in the art of warm, fuzzy claptrap. They won’t be offered what they dreamed of: that was never an option in this election.
The election’s most revealing poll was scarcely reported by the media. Those voting against Harper – sixty to seventy percent of Canada, a progressive majority holding steady through his decade in power – were asked in late September what kind of change they desired. They answered overwhelmingly: not moderate but ambitious, not incremental but immediate. In other words, most people didn’t just want Harper out: they wanted plentiful jobs, a healthy environment, indeed a far more just and fair country.

Tiny archipelago seeks to create world’s sixth-largest area to be fully protected from fishing or drilling
The tiny western Pacific archipelago of Palau has approved the creation of a marine sanctuary twice the size of Mexico.
Conservationists said the 500,000 sq km (193,000 sq mile) sanctuary would be the world’s sixth-largest fully protected area – meaning no fishing, or other uses such as drilling for oil – if it is signed into law by Palau’s president as expected on Monday.

With the right investment in infrastructure and improved liability laws, cycling in the UK could be this successful and our streets could be reclaimed as places for people of all ages to enjoy
Who builds a bicycle road on a 32km-long sea dyke? One akin to a really, really long Severn Bridge, made of earthworks, tumbleweed and gulls, with a six-lane highway? The Dutch, that’s who, and I’m grateful for it.
With no end in sight, only a straight line of smooth tarmac stretching seemingly to infinity, and bordered on both sides by sea, this bike road on the Afsluitdijk is impressive, if only for its sheer length and optimism. After two roadies and a man on a small, rattly moped overtake me at the start, there are no other cyclists using it but me, laden with panniers and tent, while motorway traffic buzzes past, at the foot of a wide, grassy bank.

UV filtering chemical is killing off baby coral around tourist resorts, particularly in the Caribbean and Hawaii
A common ingredient found in sunscreen is toxic to coral and contributing to the decline of reefs around the world, according to new research.
Oxybenzone, a UV-filtering chemical compound found in 3,500 brands of sunscreen worldwide, can be fatal to baby coral and damaging to adults in high concentrations, according to the study published on Tuesday in the Archives of Environmental Contamination and Toxicology.

Scientists have been warning for decades that human actions are pushing life on our shared planet toward mass extinction. Such extinction events have occurred five times in the past, but a bold new paper finds that this time would be fundamentally different. Fortunately, there’s still time to stop it.
Periodically, in the vast spans of time that have preceded us, our planet’s living beings have been purged by planetary catastrophes so extreme they make your typical Ice Age look like the geological equivalent of a stroll in the park. Scientists count just five mass extinctions in an unimaginably long expanse of 450 million years, but they warn we may well be entering a sixth.
According to a bold new paper in The Anthropocene Review, this time would be different from past mass extinctions in four crucial ways – and all of these stem from the impact of a single species that arrived on the scene just 200,000 years ago: Homo sapiens.
