Canada’s 2023 wildfires released more greenhouse gases than most countries

Had fires been ranked alongside countries they would have been world’s fourth-largest emitter, study finds

Wildfires that swept Canada’s woodlands last year released more greenhouse gases than some of the largest emitting countries, a study found on Wednesday, calling into question national emissions budgets that rely on forests as carbon stores.

At 647 megatonnes, the carbon released in last year’s wildfires exceeded those of seven of the 10 largest national emitters in 2022, including Germany, Japan and Russia, the study published in the journal Nature found.

South Korea’s climate law violates rights of future generations, court rules

Absence of legally binding targets for greenhouse gas reductions from 2031-49 deemed unconstitutional

South Korea’s constitutional court has ruled that part of the country’s climate law does not conform with protecting the constitutional rights of future generations, an outcome local activists are calling a “landmark decision”.

The unanimous verdict concludes four years of legal battles and sets a significant precedent for future climate-related legal actions in the region.

‘Immoral and unacceptable’: Tuvalu calls on Australia to set urgent deadline to end fossil fuels

A day after agreement was ratified at the Pacific Island Forum, the country’s climate minister says ‘root cause of climate change’ must be addressed

Tuvalu’s climate minister has declared that “opening, subsidising and exporting fossil fuels is immoral and unacceptable”, just a day after Australia ratified a climate and security deal with the low-lying Pacific nation.

The Australian prime minister, Anthony Albanese, welcomed the agreement with Tuvalu on Wednesday, saying Pacific island countries were “fully aware of the commitment that we have to climate action” but gas would continue to play a role.

‘Hyper-violent’ Typhoon Gaemi was made fiercer by climate crisis, say scientists

Researchers warn Asia will become an increasingly dangerous place to live until fossil fuels are replaced

The “hyper-violent” Typhoon Gaemi was made fiercer and more likely to strike by the climate crisis, scientists have found. They said “Asia will become an increasingly dangerous place to live until fossil fuels are replaced”.

The typhoon hit the Philippines, Taiwan and Hunan province in China in late July, with floods and landslides destroying homes, killing at least 100 people and affecting millions. Winds reaching 145mph (233 km/h) sank two large ships, while floods in Manila were as deep as a one-storey building.

This bird came back from extinction – now scientists in a glider are teaching it to migrate

Extinct in central Europe for 300 years, 36 northern bald ibis are following an ultralight aircraft on their long-forgotten migration route from Austria to Spain

The northern bald ibis was extinct in central Europe for 300 years. Now, it has returned – and scientist “foster parents” aboard a tiny plane are teaching the birds to fly their long-forgotten migration routes.

Thirty-six of these endangered birds are now following an ultralight aircraft 1,740 miles (2,800km ) from Austria to Spain, on a trip that could take up to 50 days to complete.

Corn sweat: crop moisture amplifies humidity and heat in US midwest

Moisture from crops drives up already high humidity in areas where 55 million are under extreme heat alerts

You won’t believe your ears, but corn is making the extreme heat the US midwest is battling feel more intense, according to experts.

The moisture – or “sweat” – that corn and other crops release in high temperatures is contributing to the humidity in the air in the midwest US, where 55 million people have been under alerts for extreme heat in recent days. The increase in moisture pushes up dew points, making it harder for water vapor to condensate – and for it to feel cooler.

‘A crisis entirely of humanity’s making’: UN chief issues climate SOS on trip to Pacific

António Guterres calls for a ‘massive’ increase in finance and support for the countries most vulnerable to rising sea levels

Pacific island nations are in “grave danger” from rising sea levels and the world must “answer the SOS before it is too late”, the UN chief has warned during a visit to Tonga.

The UN secretary general, António Guterres, urged the world to “look to the Pacific and listen to the science” as he released two new reports on the sidelines of the Pacific Islands Forum, the region’s most important annual political gathering.

UN chief to push for more climate change action at Pacific leaders’ summit

António Guterres to attend Pacific Islands Forum (Pif) in Tonga with climate crisis and unrest in New Caledonia among issues to watch

The UN secretary general, António Guterres, will attend a Pacific leaders’ summit this week in Tonga with a focus on climate change in the region, one of the world’s most vulnerable to rising sea levels and temperature changes.

The annual meeting of leaders is the top political decision-making body of the region. The week-long summit culminates in the leaders’ retreat, where key decisions are made, which may include an endorsement of a regional policing initiative promoted by Australia. The future for New Caledonia is among other big issues to be addressed at the Pacific Islands Forum (Pif) which began in Tonga on Monday.

Police acting as ‘private security’ for Drax power station, say climate activists

Greenpeace among 150 groups expressing outrage after preemptive arrests led to cancellation of protest camp

Greenpeace and Friends of the Earth have accused police of acting as “private security” for the UK’s biggest carbon emitter after dozens of pre-emptive arrests forced the cancellation of a climate protest camp near Drax power station.

In a statement signed by almost 150 groups, they called the operation against activists who had spent months planning the camp near the wood-burning power station “an unreasonable restriction of free speech”.

Resorts on Spain’s Costa Brava struggle with invasion of jellyfish as seas warm

Stings needing medical attention surge by 41% as rising sea temperatures due to the climate crisis boost reproduction

Costa Brava resorts in Spain’s north-east are struggling to cope with an influx of jellyfish as rising sea temperatures facilitate reproduction and drive species farther north.

Between May and August almost 7,500 people on the Catalan coast sought medical attention for jellyfish stings – a 41% increase on last year. The stings are painful and can have unpleasant consequences for anyone with compromised immunity.

Australia’s ski season could melt away early as snowfall drops to nearly half the average

August should mean peak snow depth, Jindabyne worker says, but early blast of spring threatens ‘catastrophic’ premature end to season

Australia’s snow season has begun to melt away early as unseasonable warmth cuts snowfalls to almost half the average for this time of year, experts say.

A global-heating fuelled early blast of spring weather means the season may have peaked early, with snow fields melted by warm temperatures and washed away by showers.

‘Heat engine’ fuelled by climate crisis bringing blast of summer weather to Australian winter

August temperature records threaten to break as Oodnadatta in South Australia braces for 38C and BoM forecasts above 30C in Brisbane next week

Australia is on track to face its hottest August on record as a global heating-fuelled “heat engine” brings spring and summer warmth to Australia’s winter, experts forecast.

Weatherzone meteorologist Ben Domensino said the unseasonably warm weather was coming from a “heat engine” in Australia’s red centre, where clear skies in the coming week would drive maximum temperatures towards 40C, more than 10C above average, in northern SA, southern NT, and western NSW.

Caribbean nations still facing humanitarian crisis weeks after Hurricane Beryl destruction

Category 4 hurricane that devastated the islands of St Vincent and the Grenadines when it hit the Caribbean last month has left many traumatised

From the outside, it looks like a typical primary school in the multi-island Caribbean nation of St Vincent and the Grenadines (SVG), with children’s voices echoing behind the distinctive green walls. But inside, washing lines sag with the weight of towels and clothes, and there are people of all ages: a baby frets on her mother’s hip, children squeal as they chase each other, teens play basketball, and elderly people sit on classroom chairs chatting.

This school in the district of Calliaqua is one of 20 on the country’s mainland, St Vincent, which were converted into shelters for those displaced by Hurricane Beryl, the category 4 storm which tore through the region in early July with winds of up to 120mph (193km/h).

Heat deaths in Europe may triple by end of the century, study finds

Countries in south most at risk, with rise likely to outstrip fall in cold-related deaths if global heating hits 3C or 4C

Heat deaths in Europe could triple by the end of the century, with the numbers rising disproportionately in southern European countries such as Italy, Greece and Spain, a study has found.

Cold kills more people than heat in Europe, and some have argued that climate change will benefit society by reducing those deaths. But the study, published in the Lancet Public Health, found that the death toll would respond slowly to warming weather and may even rise through people growing older and more vulnerable to dangerous temperatures.

Climate crisis fuelled storm that sank yacht in Sicily, say experts

Record sea temperatures in the Mediterranean contributed to waterspout that hit Bayesian

Record temperatures in the Mediterranean Sea this summer contributed to the freak storm that sank a superyacht off the coast of Sicily, with similar extreme events expected to increase in frequency and intensity as the climate crisis tightens its grip, Italian scientists have said.

One person is confirmed to have died and rescuers are searching for six missing people, including the British tech entrepreneur Mike Lynch and his 18-year-old daughter, Hannah, after the 56-metre Bayesian capsized in the early hours of Monday.

London City airport expansion given green light by ministers

Climate campaigners criticise decision to allow capacity to increase from 6.5m to 9m passengers a year

Ministers have approved London City airport’s application to expand, in a decision that has disappointed climate campaigners.

The airport submitted a proposal to increase capacity from 6.5 million to 9 million passengers a year by putting on more weekend and early morning flights. Local campaigners and Newham council opposed the move, arguing the air and noise pollution would affect people living nearby and that it could potentially increase carbon emissions.

Hurricane Ernesto pummels Bermuda with 35ft waves and high winds

Category 1 hurricane described as ‘rare event’ in area as officials warn of severe flooding and storm surges

Hurricane Ernesto walloped Bermuda with winds reaching 85mph (137km/h) and waves exceeding 35ft (10.5 metres) offshore from the small British territory in the Atlantic Ocean, as it made landfall early on Saturday – with officials warning of potentially fatal flooding and storm surges.

The storm arrived as a category 1 hurricane after traveling over the archipelago overnight, a trajectory described as a “rare event” by the Weather Channel. It is uncommon for the eye of tropical cyclones to pass directly over these islands, per the network.
