Methane emissions from Queensland mine may be gross underestimates, UN research finds

Posted on by

Data collected by two planes suggests large open-cut coalmine in Bowen Basin is releasing methane at higher rates than official estimates

Emissions of the potent greenhouse gas methane at a Queensland coalmine were likely between three and eight times higher than officially reported, according to UN-backed research that flew aircraft over the site.

Queensland’s open-cut coalmines are known to be a major source of methane and experts are worried that official figures could be a gross underestimation of actual emissions.

Developing countries urge biggest polluters to act as Trump’s return to the White House heightens geopolitical turmoil

The vast majority of governments are likely to miss a looming deadline to file vital plans that will determine whether or not the world has a chance of avoiding the worst ravages of climate breakdown.

Despite the urgency of the crisis, the UN is relatively relaxed at the prospect of the missed date. Officials are urging countries instead to take time to work harder on their targets to cut greenhouse gas emissions and divest from fossil fuels.

Pledge signed by experts from nine countries reflects concerns that offsets generated from forest-related projects may not have cut emissions

Carbon offsets used by corporations around the world to lower their reportable greenhouse gas emissions are “ineffectual” and “hindering the energy transition”, according to more than 60 leading climate change scientists.

A pledge signed by scientists from nine countries, including the UK, the US and Australia, said the “only path that can prevent further escalation of climate impacts” was “real zero” and not “net zero”.

Australia’s coalmines and gasfields may be emitting twice as much methane as declared, report warns

Posted on by

Superpower Institute says analysis of Queensland, NSW and Victorian sites shows need for independent reporting of greenhouse gas emissions

Australia’s coalmines and gasfields may be emitting twice as much methane as they currently declare, underscoring the need to introduce independent reporting of the potent greenhouse gas, an energy thinktank has warned.

The Superpower Institute’s Open Methane tool used satellites and ground-based verification to identify 20 “sites of concern” – all involving coal and gas operations – that are releasing “around double” the amount of methane reported.

More than £494bn subsidies a year are harmful to the climate, says report

Posted on by

ActionAid says ‘parasitic behaviour’ is fuelling the climate crisis and represents ‘corporate capture’ of public finance

More than $650bn (£494bn) a year in public subsidies goes to fossil fuel companies, intensive agriculture and other harmful industries in the developing world, new data has shown.

The subsidies entrench high greenhouse gas emissions and are fuelling the destruction of the natural world, according to a report from the charity ActionAid.

The Earth Commission says hope lies in sustainable lifestyles, a radical transformation of global politics and fair distribution of resources

All of humanity could share a prosperous, equitable future but the space for development is rapidly shrinking under pressure from a wealthy minority of ultra-consumers, a groundbreaking study has shown.

Growing environmental degradation and climate instability have pushed the Earth beyond a series of safe planetary boundaries, say the authors from the Earth Commission, but it still remains possible to carve out a “safe and just space” that would enable everyone to thrive.

Public health adviser says higher temperatures caused by climate crisis pose danger for visitors not used to them

The climate emergency poses a “real risk” to Spain’s traditional mass tourist model as rising temperatures and more frequent heatwaves hit the country’s most popular coastal destinations, a senior public health adviser has warned.

Héctor Tejero, the head of health and climate change at Spain’s health ministry, said the increasingly apparent physical impacts of the climate emergency had already led the ministry to begin talks with the British embassy on how best to educate “vulnerable” tourists about coping with the heat.

‘It’s not beautiful, but you can still eat it’: climate crisis leads to more wonky vegetables in Netherlands

Crowdfunding scheme salvages ‘imperfect’ fruit and veg following the country’s wettest autumn, winter and spring on record

When 31-year-old Dutch farmer Bastiaan Blok dug up his latest crop, the weather had taken a disastrous toll. His onions – 117,000 kilos of them – were the size of shallots.

“We had a very wet spring and a dry, warm summer, so the plants made very small roots,” said Blok, who farms 90 hectares in Swifterbant, in the reclaimed province of Flevoland. “Half of them were less than 40mm and normally at this size they aren’t even processed. We would have probably sold them for very little for biomass, or maybe to Poland for onion oil. It’s either far too wet and cold, or far too warm and dry, and there’s no normal growing period in between.”

Methane emissions: Australian cattle industry suggests shift from net zero target to ‘climate neutral’ approach

Posted on by

The US cattle industry adopted a ‘climate neutral’ goal in 2021 but scientists say that ‘misses the point’ in keeping global temperature rises below 1.5C

Cattle Australia is lobbying the red meat sector to ditch its net zero target in favour of a “climate neutral” goal that would require far more modest reductions in methane emissions.

The $75bn red meat industry, led by Meat and Livestock Australia, announced a target of reaching net zero emissions by 2030 seven years ago, in an attempt to maintain its social licence and drive investments in emissions reduction technology.

‘We need to respond now,’ says author of study that says crucial forest has already passed safe boundary and needs restoration

Up to half of the Amazon rainforest could hit a tipping point by 2050 as a result of water stress, land clearance and climate disruption, a study has shown.

The paper, which is the most comprehensive to date in its analysis of the compounding impacts of local human activity and the global climate crisis, warned that the forest had already passed a safe boundary and urged remedial action to restore degraded areas and improve the resilience of the ecosystem.

Exclusive: Prof Matt King says accelerated melting could transform country and affect viability of some agricultural industries

A leading Antarctic scientist has urged the Albanese government to pay closer attention to abrupt changes under way in the southern continent, warning they will affect Australians in ways that are little understood and research into them is drastically underfunded.

The head of the Australian Centre for Excellence in Antarctic Science, Prof Matt King, said he found it embarrassing how little was known about the local and global ramifications of changes including a historic drop in floating sea ice cover, the accelerating melting of giant ice sheets and the slowing of a deep ocean current known as the Southern Ocean overturning circulation.

Airline industry claimed science not ‘robust’ enough to implement new controls to combat climate warming caused by vapour trails

Airlines and airports opposed measures to combat global warming caused by jet vapour trails that evidence suggests account for more than half of the aviation industry’s climate impact, new documents reveal.

The industry argued in government submissions that the science was not “robust” enough to justify reduction targets for these non-CO2 emissions. Scientists say the climate impact of vapour trails, or contrails, has been known for more than two decades, with one accusing the industry of a “typical climate denialist strategy”.
