The battle for the future of Stonehenge

Britain’s favourite monument is stuck in the middle of a bad-tempered row over road traffic. By Charlotte Higgins

Stonehenge, with the possible exception of Big Ben, is Britain’s most recognisable monument. As a symbol of the nation’s antiquity, it is our Parthenon, our pyramids – although, admittedly, less impressive. Neil MacGregor, the former director of the British Museum, recalls that when he took a group of Egyptian archaeologists to see it, they were baffled by our national devotion to the stones, which, compared to the refined surfaces of the pyramids, seemed to them like something hastily thrown up over a weekend.

Unlike those other monuments, though, Stonehenge is more or less a complete mystery. Nobody knows for sure why, or by whom, this vast arrangement of boulders was erected on Wiltshire’s downlands, in the south of England, about 5,000 years ago. Into this void have rushed myriad theories, from the academically sober to the blatantly fantastic. Over the centuries, its construction has been confidently credited to giants, wizards, Phoenicians, Mycenaeans, Romans, Saxons, Danes and aliens. (According to one medieval theory, Merlin had it transported from Ireland to serve as the funeral monument for Britons slaughtered by Hengist, the treacherous Saxon.)

Australia can meet its Paris targets – if government doesn’t hinder progress

ANU research suggests net cost of achieving Paris targets is zero because renewables are now cheaper than fossil fuels

New research finds Australia is installing renewable energy faster than any other country, a trend that will allow Australia to meet its economy-wide Paris targets five years ahead of schedule if politics doesn’t derail the trend, according to new research from the Australian National University.

While emissions have been rising across the economy since the Abbott government repealed the carbon price after winning government in 2013, they have been falling in the electricity sector because of the closure of ageing coal plants and the rapid uptake of renewables.

Cavity two-thirds the size of Manhattan discovered under Antarctic glacier

Disintegration of rapidly melting Thwaites ice mass could threaten coastal communities worldwide

Scientists have discovered a giant cavity at the bottom of a disintegrating glacier in Antarctica, sparking concerns that the ice sheet is melting more rapidly than expected.

Researchers working as part of a Nasa-led study found the cavern, which they said was 300 metres tall and two-thirds the size of Manhattan, at the bottom of the massive Thwaites glacier.

‘That’s going to burst’: Brazilian dam workers say they warned of disaster

Fears and repairs preceded January collapse in which 134 people died and 199 are still missing, near Brumadinho in Minas Gerais state

The Brazilian mining dam which collapsed in January, killing hundreds of people, suffered a leak last year that compromised its safety, according to employees who allege the mine’s operators did not inform the workforce or relocate a canteen and administration building that were destroyed in the disaster.

One hundred and forty-two people died and 194 are still missing after the dam near Brumadinho in Minas Gerais state collapsed on 25 January.

‘Beggars belief’: more endangered parrots exported from Australia

Warren Entsch demands investigation after German convicted kidnapper boasts about new shipment

A government MP has said it “beggars belief” that more endangered Australian birds have been exported to a German organisation headed by a convicted kidnapper and extortionist, after a Guardian investigation revealed there had been multiple warnings that the birds could be sold to collectors at a huge profit.

Warren Entsch repeated calls for an independent investigation into how the Association for the Conservation of Threatened Parrots was able to receive hundreds of rare and endangered birds from Australia, after its founder, Martin Guth, used a social media post to say more endangered species had arrived at its facilities in January.

‘We have to learn to live with floods’: waterlogged Surat to become latest megacity

The next 15 megacities #14: Surat’s battle to hold back water has raged since its first flood wall in 1664. As its population soars, India’s ‘diamond city’ needs new solutions

Look up as you walk around Surat and you might spot “HFL 8.8.2006” daubed in red paint on a wall above your head. HFL stands for “high flood level”, and the inscriptions are 15 feet above the ground in places – a fading memory of the devastating floods of August 2006, which killed 150 people, according to official estimates (unofficial counts put the death toll at over 500). More than 60% of the city was underwater and damage was estimated at $2bn.

Surat’s geography – it lies at the mouth of the Tapi river, near the Arabian Sea – makes it prone to flooding, and it experiences a major inundation every four years on average.

A third of Himalayan ice cap doomed, finds report

Even radical climate change action won’t save glaciers, endangering 2 billion people

At least a third of the huge ice fields in Asia’s towering mountain chain are doomed to melt due to climate change, according to a landmark report, with serious consequences for almost 2 billion people.

Even if carbon emissions are dramatically and rapidly cut and succeed in limiting global warming to 1.5C, 36% of the glaciers along in the Hindu Kush and Himalaya range will have gone by 2100. If emissions are not cut, the loss soars to two-thirds, the report found.

Australian authorities deliberately flood 2,000 Queensland homes after record downpours

State government warns residents to beware of crocodiles and snakes, which were reportedly heading into suburban areas

After eight days of heavy monsoonal rain, authorities in the north Queensland city of Townsville had no choice but to open the floodgates of the Ross River Dam, deliberately flooding about 2,000 homes.

The decision was made as the Queensland government also published a warning to people to beware of crocodiles, snakes and other wildlife, which were reported to have left the swollen river and headed into some suburban areas.

Queensland flooding: thousands of homes in Townsville under threat as waters rise – live

Torrential rain forces authorities to open Ross River dam floodgates, releasing 1,900 litres a second in ‘once-in-a-century flood’. Follow all the developments • Townsville floods: Queensland premier warns ‘we haven’t got to the peak’

At this stage, authorities expect the Ross River to peak about 11am, and for the peak to last most of today.

That’s potentially good news for Townsville residents, especially those under threat but not yet underwater. It’s also a sign that the flood emergency is unlikely to end any time soon.

Overnight, Townsville residents were warned to stay out of the water – and for good reason. A number of crocodiles sightings have been reported, while the authorities also warned of snakes in the water.

Queensland floods: emergency dam release as Townsville hit by 1.1 metre of rain

Up to 100 more homes face flooding after mayor orders high-risk plan to open floodgates on the Ross River dam

One hundred homes could be flooded in Townsville after the city’s mayor sanctioned the high-risk release of dam water to save the area from more widespread inundation following more than 1.1 metres of rain.

Announcing the emergency measure for the Ross River dam on Friday, the mayor Jenny Hill said there were no guarantees the plan would work. Between 90 and 100 homes downstream from the dam were being evacuated, she added.

Trump appoints climate change skeptic to EPA science board – latest news

Controversial climatologist John Christy, who once said scientists believed Earth was flat, to join advisory board at environment agency

Progressives are preparing to take on Starbucks CEO Howard Shultz — who is considering a run for president in 2020 as an independent — hoping to arm themselves with information about the billionaire’s governmental dealings.

Axios reports that Democratic super PAC, Priorities USA, has requested documents from roughly 70 national and state agencies who may have connected with Shultz or his coffee company over the last 3 decades:

The group is gathering as much potential opposition research as they can on Schultz and his business in anticipation of his decision to possibly run for president as an independent. This is yet another example of liberals trying to push Schultz out of the 2020 race before he begins, in part because they view his candidacy as a “threat” that could be “a major step toward re-electing Donald Trump,” Priorities USA communications director Josh Schwerin told Axios”.

A new poll released by Monmouth University says more than 60% of Americans think the president knew that high-ranking members of his campaign lied to investigators and half believe he asked them to do it.

The survey also found that there’s still significant concern among the electorate that Russia has influence over Trump, and that not enough has been done to stop the Kremlin from meddling into elections.

Was Trump aware of campaign associated trying to mislead investigators or Congress?

62% Yes
32% No

Do you think Trump personally asked people to mislead investigators or Congress?

50% Yes
42% No

Monmouth poll

‘Views of the president’s ties to Russia look like almost any other aspect of public opinion related to Trump. Very few Republicans believe anything negative about him and nearly all Democrats are inclined to accept damaging information, while independents are almost evenly split’, said Murray.

Just over half of Americans (51%) feel that the special counsel’s investigation into Russian election interference and possible links to the Trump campaign should continue. Another 45% say this investigation should be brought to an end. Support for continuing the special counsel investigation has hovered between 52% and 54% in polls taken between April and November 2018. Prior to that, about 6-in-10 Americans supported continuing the investigation (60% in March 2018 and 62% in July 2017)“.

Josh Frydenberg defends Coalition’s climate record as he faces challenge in Kooyong

Treasurer says climate change is real and Scott Morrison’s government takes emissions reduction ‘very seriously’

Josh Frydenberg has defended the Coalition’s record on climate change and says he will work hard to earn the trust of his constituents in the face of a challenge from long-time Liberal and now independent Oliver Yates.

Yates, a former Macquarie banker and head of the Clean Energy Finance Corporation, confirmed on Wednesday he would run in Kooyong at the coming federal election, declaring Frydenberg deserved to be challenged because of a lack of action on the environment.

The miracle method for sustainable rice that scientists dismissed | John Vidal

A technique developed by a Jesuit priest is producing bigger harvests – and reducing emissions of a crop responsible for 1.5% of greenhouse gases

The fragrant jasmine rice growing on the left side of Kreaougkra Junpeng’s five-acre field stands nearly five feet tall.

Each plant has 15 or more tillers, or stalks, and the grains hang heavy from them. The Thai farmer says this will be his best-ever harvest in 30 years and he will reap it four weeks earlier than usual.
