Records being broken for greenhouse gas pollution, surface temperatures and ocean heat

The world has never been closer to breaching the 1.5C (2.7F) global heating limit, even if only temporarily, the United Nations’ weather agency has warned.

The World Meteorological Organization (WMO) confirmed on Tuesday that 2023 was the hottest year on record by a wide margin. In a report on the climate, it found that records were “once again broken, and in some cases smashed” for key indicators such as greenhouse gas pollution, surface temperatures, ocean heat and acidification, sea level rise, Antarctic sea ice cover and glacier retreat.

Neither the Tories nor Labour seem bothered by the climate mayhem that awaits us, but to save lives they must act

It’s the August bank holiday in 2050 and the UK is sweltering under the worst heatwave on record. Temperatures across much of England have topped 40C for eight days running: they peaked at 46C, and remain above 30C in cities and large towns at night. The country’s poorly insulated homes feel like furnaces, and thousands of people have resorted to camping out at night in the streets and local parks in a desperate attempt to find sleep. Hospital A&Es are overwhelmed and wards are flooded with patients, mostly old and vulnerable people who have succumbed to dehydration and heatstroke. Already, the death toll is estimated at more than 80,000.

No, this isn’t the beginning of a dystopian drama, but a snapshot of a mid-century heatwave unless we prepare for the increasingly extreme weather that will be driven by climate breakdown. To say that the government has no credible plan for this, as the UK Climate Change Committee did last week, is – if anything – an understatement. Britain is woefully underprepared for extreme weather, and in a number of key areas we are going backwards. About one in 15 of England’s most important flood defences were in a poor or very poor condition in 2022, up from roughly one in 25 just four years previously. The government’s Great British insulation scheme is operating at such a slow pace that it would take nearly 200 years to upgrade the country’s housing stock, while Labour has rowed back on its ambitious plans to insulate 19m homes within a decade.

Australia’s leading scientific research body received just $100,000 a year towards combatting fire ants, a Senate inquiry into the highly invasive pests has heard.

At the third and final session of public hearings for the Senate inquiry on Monday, the committee’s chair, Senator Matt Canavan, said some of the evidence he had heard had “freaked [him] out”.

How can we expect people to care for the countryside if they are denied access to it? We must fight for our right to roam

When people ask me where I’m from, I wryly tell them “the middle of nowhere”. So, imagine my surprise when I saw that my old landlord and the remote place where I grew up were making national headlines over a court battle for the right to wild camp on Dartmoor.

Alexander Darwall bought the 1,619-hectare (4,000-acre) Blachford estate on southern Dartmoor in 2011. Dartmoor is the only place in England where wild camping is allowed, in designated areas, without permission from a landowner. Darwall successfully contested this right in court, arguing that the right to wild camp – as opposed to walking or picnicking – on the moors never existed. Then an appeal restored it. Now, he’s taking the case to the supreme court.

Court of appeal’s removal of ‘consent’ defence means defendants on trial for criminal damage can no longer use it

It took a matter of minutes in the court of appeal, where demonstrators were strangely absent, for the dial to shift once more on the rights of protest in England and Wales.

The decision taken on Monday by the court of appeal to, in effect, find in favour of the attorney general, the Conservative government’s premier legal officer, has removed a defence for climate protesters that had been available on the statute books since 1971.

Almost all countries failing to meet mark for PM2.5, tiny particles expelled by vehicles and industry that can cause health problems

Only seven countries are meeting an international air quality standard, with deadly air pollution worsening in places due to a rebound in economic activity and the toxic impact of wildfire smoke, a new report has found.

Of 134 countries and regions surveyed in the report, only seven – Australia, Estonia, Finland, Grenada, Iceland, Mauritius and New Zealand – are meeting a World Health Organization (WHO) guideline limit for tiny airborne particles expelled by cars, trucks and industrial processes.

We should focus on rooftop solar – Australians love it

A missing element from much of the debate about whether Australia should embrace nuclear power is that – unless the Labor rank-and-file have an extraordinary change of heart – the issue is already dead on arrival.

John Howard and Scott Morrison knew the score on this. Unless there is bipartisan support, a nuclear industry has virtually no chance of being developed. And as things stand there is no chance of the ALP changing its position.

Labour shadow energy minister will use speech to say Tory approach is also leading to higher bills

Ministers are stoking the fires of the culture wars over the UK’s net zero target instead of addressing the urgency of the climate crisis, Ed Miliband will say.

The shadow energy secretary will make a pitch directly to Conservative voters who are concerned that the party has made major U-turns on cutting greenhouse gas emissions amid increasingly anti-green rhetoric.

China’s Longi looks to slash costs as renewable energy sector faces tough headwinds from inflation

The world’s largest solar manufacturer has slashed nearly a third of its workforce after a cost-cutting drive that included telling staff to only print in black and white fell short and as a chill ripples through the renewable energy sector.

China’s Longi is to cut as much as 30% of its workforce, in an acceleration of cost reductions that began late last year, Bloomberg reported.

Appeal court says defendants’ ‘beliefs and motivation’ do not constitute lawful excuse for damaging property

One of the last defences for climate protesters who commit criminal damage has been in effect removed by the court of appeal. The court said the “beliefs and motivation” of a defendant do not constitute lawful excuse for causing damage to a property.

The defence that a person honestly believes the owner of a property would have consented had they known the full circumstances of climate change has been used successfully over the last year by protesters.

Academic experts also criticise UN Food and Agriculture Organization for dismissing alternative proteins

The omission of meat-eating reduction from proposals in a UN roadmap to tackle the climate crisis and end hunger is “bewildering”, according to academic experts.

The group also criticised the UN Food and Agriculture Organization’s report for “dismissing” the potential of alternative proteins, such as plant-based meat, to reduce the impact of livestock on the environment.

Greenpeace has called for the creation of a high seas protected zone under a new UN treaty to secure a much wider area around Ecuador’s Galapagos archipelago, whose unique fauna and flora inspired Charles Darwin’s theory of evolution

Perhaps our government imagines bulldog spirit will protect us from the dangerous substances that Europe rules unsafe

It’s a benefit of Brexit – but only if you’re a manufacturer or distributor of toxic chemicals. For the rest of us, it’s another load we have to carry on behalf of the shysters and corner-cutters who lobbied for the UK to leave the EU.

The government insisted on a separate regulatory system for chemicals. At first sight, it’s senseless: chemical regulation is extremely complicated and expensive. Why replicate an EU system that costs many millions of euros and employs a small army of scientists and administrators? Why not simply adopt as UK standards the decisions it makes? After all, common regulatory standards make trading with the rest of Europe easier. Well, now we know. A separate system allows the UK to become a dumping ground for the chemicals that Europe rules unsafe.

Installations must speed up 11-fold as advisers say latest changes to scheme likely to make 2028 target even harder

The public spending watchdog has criticised the slow pace of the government’s heat pump rollout just days after ministers postponed an important scheme designed to increase the rate of installations.

A report by the National Audit Office (NAO) has found that heat pump installations would need to accelerate 11-fold if the government is to reach its target for 600,000 heat pumps installed in homes every year by 2028.

Financiers providing billion-dollar support for industrial livestock companies to expand leading to unsustainable rise in production

Billion-dollar financing is driving unsustainable increases in global meat and dairy production, a report has found.

Global meat production rose 9% between 2015 and 2021, the report said, while dairy production increased 13% in that time.

What better way to test if Australians are up for nuclear energy than by asking them: Do you support removing the current ban? Would you support a reactor in your area?

When the Coalition was paralysed by whether or not to legislate marriage equality, it turned to the wisdom of the people.

The plebiscite was divisive, an obstacle to marriage equality which could have been dealt with by a free parliamentary vote, and which many queer people felt was a referendum on their dignity.

Blockades at facilities in Germany, the Netherlands, Norway and Sweden, with protests in Scotland and action expected in Denmark

Climate activists in four countries are blocking access to North Sea oil infrastructure as part of a coordinated pan-European civil disobedience protest.

Blockades have been taking place at oil and gas terminals, refineries and ports in Germany, the Netherlands, Norway and Sweden, in protest at the continued exploitation of North Sea fossil fuel deposits.

Researchers found that the Victorians brought so many seeds and saplings to Britain that the trees now outnumber those in their US homeland

Three redwoods tower over Wakehurst’s Elizabethan mansion like skyscrapers. Yet at 40 metres (131ft) high, these are almost saplings – not even 150 years old and already almost twice as high as Cleopatra’s Needle.

“At the moment they’re some of the tallest trees in the UK and they are starting to poke above the forest canopy. But if they grow to their full potential, they’re going to be three times taller than most trees,” says Dr Phil Wilkes, part of the research team at Wakehurst, in West Sussex, an outpost of Kew Gardens. One or two of these California imports would be curiosities, such as the 100-metre high redwood that was stripped of its bark in 1854 and exhibited to Victorian crowds at the Crystal Palace in south-east London, until it was destroyed by fire in 1866.

GPs with convictions over protests face tribunals to determine whether they can keep licence to practise

Dr Sarah Benn has long been concerned about the climate crisis, diligently recycling until she was “blue in the face”. But the rise of the climate activist group Extinction Rebellion in 2019 inspired her and her husband to go further. “We thought: well, if we don’t do it then who else is going to?”

While working as a GP near Birmingham, Benn became increasingly involved in direct action over the next few years, and once glued her hand to the door of the Department for Business, Energy, and Industrial Strategy in protest at the government’s inaction on the climate.

Charging townspeople to use a beautiful park in the Cotswolds may ignite a wider right to roam movement

A small outcry over the imposition of entrance fees to Cirencester Park is an interesting moment, and it may prove more significant than it first appears. Sir Benjamin Bathurst, a wealthy slave trader, acquired the stunning estate in 1695 and it remains in the family’s hands. The park sits beside the town of Cirencester and, ever since its inception, people have been allowed through the gates for walking, playing and imbibing the scent of lime blossom from its magnificent avenue of mature trees.

The parkland, landscaped in the 18th century, has been the de facto town park: children have climbed trees there, and residents with tiny back yards have enjoyed the many scientifically proven physical and mental health benefits of exercising in a very large green back yard. There are similar arrangements at other estates, such as Blenheim, where the townsfolk of Woodstock – similarly adjacent to estate walls – can wander fairly freely into vast swathes of parkland on their doorstep.
