Big trees in Amazon more climate-resistant than previously believed

Posted on by

Forest is ‘remarkably resilient to climate change’, but remains under threat from fires and deforestation

The biggest trees in the Amazon are growing larger and more numerous, according to a new study that shows how an intact rainforest can help draw carbon dioxide out of the atmosphere and sequester it in bark, trunk, branch and root.

Scientists said the paper, published in Nature Plants on Thursday, was welcome confirmation that big trees are proving more climate resilient than previously believed, and undisturbed tropical vegetation continues to act as an effective carbon sink despite rising temperatures and strong droughts.

China has announced its first target to cut emissions in real terms. What does it mean for Australia?

Posted on by

With China accounting for nearly a third of the world’s total emissions, any cuts it achieves will make a substantial difference for the world – and for fossil fuel exports

Anything China does on energy and climate change is very big news. Its plans ripple around the world, whether that’s in changing the demand for fossil fuels or affecting the impacts on the planet from global heating.

On Thursday, Australia woke to the news that China’s president, Xi Jinping, had told the United Nations that for the first time his country was setting a target to cut – in absolute terms – its greenhouse gas emissions.

Leaders unveil new targets to cut planet-heating pollution after Trump called climate crisis a ‘con job’

World leaders have unveiled new targets to cut planet-heating pollution at the United Nations, in a bid to spur fresh impetus to the beleaguered climate effort a day after Donald Trump called the crisis “the greatest con job ever perpetrated upon the world”.

A total of 120 countries and the European Union announced new goals to reduce greenhouse-gas emissions in New York on Wednesday. The pledges most notably include one from China, the world’s leading emitter, which said it would cut emissions by 7-10% from its peak level by 2035.

Ralph Regenvanu, minister of climate change for the Pacific island nation, says step taken on ‘behalf of everybody’

Vanuatu is working on securing a UN vote to turn a landmark ruling on the climate crisis by the international court of justice (ICJ) into concrete political action that will fight the influence of the fossil-fuel industry and protect the globe from environmental catastrophe.

In an effort spearheaded by the tiny Pacific island nation, the ICJ issued a rare unanimous advisory opinion in July, which clarified that all states are required under international law to protect the climate, prevent further harms and have a duty to cooperate.

Sun Day national action supported renewable energy, day after ‘Make Billionaires Pay’ march ahead of Climate Week

Hundreds of environmentalists gathered in New York City’s Stuyvesant Square Park and a nearby Quaker meeting house on Sunday to rally in support of solar power and other forms of renewable energy. The event was part of a national “day of action” billed Sun Day, founded by veteran environmental activist Bill McKibben and first Earth Day coordinator Denis Hayes.

“It’s so sad to watch the sun going to waste,” McKibben said at a press conference, standing beside environmentalists and their children. “Every single day, energy from heaven going to waste while we drill down to hell for another dose of the stuff that is wrecking this planet.”

Two-year-old boy dies and homes buried as remnants of Tropical Storm Mario bring downpours and thunder

Flash flooding and landslides led to the death of a two-year-old boy in California in the US last week, after heavy rainfall followed on the heels of Tropical Storm Mario further south. The storm skirted the Pacific coast of Mexico with minimal disruption, eventually dissipating to the west of Baja California on Tuesday, but the remnants went on to cause havoc on Thursday. Residual moist air from the tropical storm was drawn north-east towards California, bringing heavy downpours and thunder to central and southern counties.

The heaviest rainfall was in the mountains of Riverside and San Bernardino counties, where up to 68mm (2.67in) fell in a few hours. Further north, Death Valley – famously one of the driest places on Earth – received 15mm of rain, triple the average rainfall for September and a full quarter of the yearly average.

Queensland Nationals senator tells Cpac conference ‘last rites being administered’ and praises Andrew Hastie for threat to quit frontbench over policy

Nationals senator Matt Canavan has claimed the Coalition is “on the cusp of walking away from net zero”, urging Sussan Ley to campaign against the emissions reduction target by taking inspiration from Peter Dutton’s opposition to the Indigenous voice referendum.

The conservative political conference Cpac has heaped more pressure on Ley to dump the climate target, with a host of rightwing Liberal and National politicians calling for the 2050 aspiration – agreed by the former Coalition prime minister Scott Morrison – to be scrapped immediately.

Kenya’s Turkana people genetically adapted to live in harsh environment, study suggests

Posted on by

Research which began with conversations round a campfire and went on to examine 7m gene variants shows how people survive with little water and a meat-rich diet

A collaboration between African and American researchers and a community living in one of the most hostile landscapes of northern Kenya has uncovered key genetic adaptations that explain how pastoralist people have been able to thrive in the region.

Underlying the population’s abilities to live in Turkana, a place defined by extreme heat, water scarcity and limited vegetation, has been hundreds of years of natural selection, according to a study published in Science.

Liberal leader later clarifies she doesn’t support setting targets while in opposition

The Liberal leader, Sussan Ley, has indicated the Coalition won’t set a 2030 or 2035 climate target unless they return to government, saying her colleagues didn’t back locking in an emissions goal while they remained in opposition.

It came as Ley had to clean up her own error, claiming she “misspoke” after initially saying her party “don’t believe in setting targets at all from opposition or from government”. She later clarified she only meant in opposition, prompting ridicule from Anthony Albanese who claimed the opposition “changes its policies from hour to hour”.

Albanese’s Oprah-style emissions target aims to please almost everyone but risks falling short on climate action

Posted on by

The prime minister has a stonking majority and a progressive crossbench that wants deeper cuts. So what has happened to lower the goal?

The Australian government has announced an Oprah Winfrey-style emissions target for 2035. It has tried to promise (nearly) everyone a prize.

By choosing a target range of a 62% to 70% cut compared with 2005 levels – based on long-awaited advice from the Climate Change Authority and its chair, Matt Kean – it has opted for a political solution.

‘We’re still in the dark’: a missing land defender and the deadly toll of land conflict on Indigenous people

Posted on by

Julia Chuñil is one of 146 land defenders who were killed or went missing last year, a third of them from Indigenous communities

One day last November, Julia Chuñil called for her dog, Cholito, and they set off into the woods around her home to search for lost livestock. The animals returned but Chuñil, who was 72 at the time, and Cholito did not.

More than 100 people joined her family in a search lasting weeks in the steep, wet and densely overgrown terrain of Chile’s ancient Valdivian forest. After a month, they even kept an eye on vultures for any grim signs. But they found no trace of Chuñil.

Accommodation costs at climate summit in Belem are pricing out some developing countries and media outlets

The United Nations has urged its staff to limit attendance at the Cop30 climate summit in Brazil in November due to high accommodation prices, while government delegations are still scrambling to find rooms within their budgets.

The move comes as delegations grow increasingly concerned about the cost of accommodation in the coastal Amazon city of Belem hosting Cop30. Brazil said it is working to increase the number of available hotel beds, but soaring prices for accommodation have stoked calls from some governments to relocate the conference, which Brazilian officials have rejected.

Campaigners crowdfund £26,000 to seek judicial review of move to construct pitches in wildlife-rich area

Campaigners are mounting another legal challenge to the building of a women’s football academy by Tottenham Hotspur on wildlife-rich parkland in north London.

The Guardians of Whitewebbs group has successfully crowdfunded £26,000 to seek a judicial review of Enfield council’s granting of planning permission for the Spurs academy, which will include all-weather pitches, floodlights and a turf academy built on 53 hectares (130 acres) of Whitewebbs Park. Enfield council’s planning committee approved the proposals in February, despite local protests, on greenbelt parkland rich in bats, newts and mature trees.
