Fire ants breach Queensland containment zones six times as authorities try to stop march to NSW border

Experts say pest eradication program is underfunded and it is a ‘matter of time’ before ants move beyond Queensland

Fire ants have breached containment zones in south-east Queensland six times in the past six weeks, triggering the expansion of biosecurity controls at the New South Wales border.

The imported red fire ants – considered one of the world’s worst invasive species – were detected at a site at Tallebudgera last week, about 5.5km from the NSW border. The find was the farthest south the pest has been detected in Queensland.

Tensions emerge between state and federal governments over Australia’s energy grid roadmap

Exclusive: disquiet points to jockeying among jurisdictions and impatience over the rollout of renewables

Cracks in the unity of the nation’s energy ministers have emerged amid disquiet over a review of power grid plans and an effort by the federal government to force carbon offsets from big new gas fields on to the states.

Almost two weeks on from a gathering of energy and climate ministers in Tasmania, senior officials expressed concern about how the review of the integrated system plan (ISP) – the grid’s roadmap – would be handled. One concern was that the federal energy minister, Chris Bowen’s department would be handling the review.

Science and business leaders say lurch away from climate agenda after byelections would be deeply unpopular with voters and damage UK’s reputation

Britain’s leaders have been warned against a “politically suicidal” lurch away from their green pledges as concerns grow that both major parties may dilute their plans to combat the climate crisis in the wake of a shock byelection result.

Senior figures from business, the scientific community and across the political divide warned that any watering down of climate policies would be deeply unpopular with voters, set back the international fight to reach net zero and damage Britain’s green reputation.

Good morning.

When the temperature in Sicily is approaching 50C, you know something is wrong.

New Zealand | Two people died and six people were injured after a shooting at a building site in Auckland city centre, hours before the Women’s World Cup is due to start. The gunman was also dead. New Zealand’s PM, Chris Hipkins, said the World Cup would proceed as planned.

Politics | Almost 200,000 families living under Labour-run councils are affected by the two-child benefit cap, a Guardian analysis has revealed. Keir Starmer’s decision not to scrap the policy if Labour wins power has led to attacks from anti-poverty campaigners and disquiet from senior figures in the party.

Health | MPs have urged the government to introduce restrictions on the packaging and marketing of disposable vapes to tackle the “alarming trend” of children using these addictive products. The health and social care committee said there should be restrictions on how e-cigarettes are sold, in line with those applied to tobacco products.

Slavery | Caribbean countries are considering approaching the UN’s international court of justice for a legal opinion on demanding compensation from 10 European countries over slavery, as the fight for reparative justice is stepped up. Ralph Gonsalves, the current leader of the Community of Latin American and Caribbean States, said he is also looking for an apology from the British government and expressed disappointment in Rishi Sunak’s lack of engagement in the matter.

Strikes | A strike by train staff in the RMT union will severely affect rail services across Britain in the next week. About 20,000 RMT members at 14 train operators will strike for 24 hours on Thursday and again on Saturday, coinciding with the end of a week-long overtime ban by train drivers in the Aslef union. The 10 days of transport disruption will coincide with the peak summer holiday getaway weekend.

Eastern Australia hit with rising electricity prices despite record warm weather

Wind output reached record levels in June in the national electricity market, the Australian Energy Regulator said

Eastern Australia’s wholesale power prices increased in the June quarter, although they remained well below the level reached during the energy crisis a year earlier, the Australian Energy Regulator has said.

New South Wales posted the highest spot pricing with an average of $148 a megawatt-hour, up from just over $100/MWh during the first three months of the year. During last winter’s energy squeeze, prices averaged about $320/MWh.

EU to invest €45bn in Latin America and Caribbean

Package includes projects to extract minerals, electrify bus fleets and help protect Amazon rainforest

EU leaders in Brussels have announced €45bn (£39bn) in investments to Latin America and the Caribbean, some of which will speed the shift to clean energy, but made little headway thawing a frozen trade deal that critics say will further degrade the Amazon rainforest.

The EU-Celac summit, the first of its kind since 2015, aimed to bring the EU closer to Latin American and Caribbean countries. Disagreements over how to refer to the war in Ukraine in the final text soured negotiations.

Researchers find evidence of ‘forever chemicals’ in blood of pregnant women

At least 97% of the blood samples contained a type of PFAS known as PFOS, associated with multiple serious health problems

California researchers have found new evidence that several chemicals used in plastic production and a wide array of other industrial applications are commonly present in the blood of pregnant women, creating increased health risks for mothers and their babies.

The researchers said their findings add to a growing body of evidence showing that many chemicals people are routinely exposed to are leading to subtle but harmful changes in health. The work should be a “wake-up call” to policymakers, they said.

Light and noise pollution ‘are neglected health hazards’, say peers

Lords committee calls for creation of advisory groups to tackle the pollutants, which may increase risk of heart disease and premature death

Light and noise are “neglected pollutants” that are causing significant harm to human health and can cause premature deaths, a group of peers have said.

The science and technology committee of the House of Lords has called on ministers to do more to tackle these pollutants, which it claims are “poorly understood and poorly regulated”.

Olive oil industry in crisis as Europe’s heatwave threatens another harvest

World’s biggest olive producer, Spain, on course for second bad harvest in a row, raising fears of gaps on shelves and even higher prices

The olive oil industry is “in crisis”, with the heatwave in southern Europe threatening to inflict the second bad harvest in a row and gaps on shelves this autumn.

After a spring heatwave affected flowering in Spain, which produces about half the global olive crop, the harvest was forecast to be only 28% up on last year, which was the worst in almost a decade.

Italian media more focused on foreign coverage of heatwave than its effects

Reporting of climate crisis has been lousy for years, experts say, in a country where rightwing press has been dominant

Italy is sweltering in abnormally high temperatures, but its media appear to be more interested in how the extreme heat is being reported in the foreign press than delving deeply into the effects in a country deemed to be among the most vulnerable in Europe to the climate crisis.

Over the weekend, several outlets picked up on reports on Italy’s heatwave in leading foreign news websites – including the Guardian, the Times and the BBC. They were particularly fascinated by a headline in the Times calling Rome – where temperatures are forecast to reach highs of 43C on Tuesday – the “Infernal City”, a play on the nickname “Eternal City”. So much so that it was still a talking point come Monday.
