Smoke from Australian bushfires depleted ozone layer by up to 5% in 2020, study finds

Lead researcher says destruction was similar to process of Antarctic ozone hole forming each spring ‘but at much warmer temperatures’

Particles in bushfire smoke can activate molecules that destroy the ozone layer, according to new research that suggests future ozone recovery may be delayed by increasingly intense and frequent fires.

A study published in the journal Nature has found that smoke from the 2019-20 Australian bushfires temporarily depleted the ozone layer by 3% to 5% in 2020.

Revealed: cabinet ministers warned of legal action over UK’s failure to tackle climate crisis

Senior civil servants have issued the warning as government is way behind on net zero pledges, according to leaked documents

Cabinet ministers have been warned by senior civil servants that they face court action because of their catastrophic failure to develop policies for tackling climate change, according to secret documents obtained by the Observer.

The leaked briefings from senior mandarins – marked “official sensitive” and dated 20 February this year – make clear the government as a whole is way behind in spelling out how it will reach its net zero targets and comply with legal duties to save the planet.

Unprecedented snowfall on US west coast is ‘once-in-a-generation’ event

California governor declares state of emergency in 13 counties while Portland, Oregon, sees second snowiest day in history

The west coast of the US, from Oregon to the mountains of California and the golf courses of Phoenix, has received nearly unprecedented levels of snowfall this week in what officials are calling a “once-in-a-generation” event.

The mountainous regions of California have received so much snowfall – more than 40ft of snow since the start of the season – that entire towns have shut down as they are virtually cut off from the rest of the state. The governor has declared a state of emergency in 13 counties due to the unusual snowfall.

David Pocock wants urgent action on carbon credit system ahead of vote on key climate policy

Crossbench senator’s support is crucial if government is to introduce planned revamp of safeguard mechanism

Independent senator David Pocock has urged the Albanese government to quickly implement all recommendations from a review of Australia’s carbon credit system, given it wants to introduce a climate policy that relies heavily on offsets.

Pocock’s is a key vote if the government is to introduce a planned revamp of the safeguard mechanism, a scheme that is meant to reduce carbon pollution from 215 big polluting industrial and resources sites.

‘A part of winter is missing’: Ottawa grieves over lack of canal ice for skating

Rideau has not turned into world’s long ice rink as usual, laying bare unpredictable realities of climate crisis

Every winter for more than two decades, Chris Macknie has laced up boots, clipped on skis or slipped on running shoes to compete in Ottawa’s Winterlude triathlon.

The event, held in dead of winter, has hundreds skate along the frozen Rideau canal, swapping out their blades for nordic skis and then finish with a run.

Carbon emissions from global SUV fleet outweighs most countries

Popularity of sport utility vehicles driving higher oil demand and climate crisis, say experts

The continued global rise in the sale of SUVs pushed their climate-heating emissions to almost a billion tonnes of carbon dioxide in 2022, according to the International Energy Agency.

The 330m sport utility vehicles on the roads produced emissions equivalent to the combined national emissions of the UK and Germany last year. If SUVs were a country, they would rank as the sixth most polluting in the world.

Confusion surrounds China’s energy policies as GDP and climate goals clash

Wave of permits for coal-fired power plants sparks concern as ambitions for GDP growth and lowering emissions come into conflict

China’s energy policies are fast creating a type of “emissions ambiguity”, as the twin goals of boosting GDP growth and reducing carbon emissions come into conflict.

The uncertainty is whether and when the world’s biggest carbon emitter will start to curb greenhouse gas pollution. The release of the country’s annual statistics communique on Tuesday did not clear things up.

Methane emissions ‘incredibly cheap’ to cut without needing offsets, safeguard mechanism inquiry told

Hearing into Labor’s changes to the scheme told a 75% reduction in methane was possible using commercially competitive existing technology

Methane emissions from the oil and gas industry are “incredibly cheap” to cut and companies could improve their financial position by embracing existing technology to stop carbon leaks, an inquiry into the Albanese government’s climate policy has heard.

A hearing into proposed changes to the safeguard mechanism – a Coalition policy applied to industrial emissions that Labor plans to revamp – was told the International Energy Agency (IEA) had estimated a 75% reduction in methane was possible using commercially competitive existing technology, such as capturing the methane and using it to generate electricity.

Chris Bowen urges Greens to back emissions bill but again rules out ban on new fossil fuel projects

Greens leader says party has already made significant compromises on the safeguard mechanism

Australia’s climate minister, Chris Bowen, has again challenged the Greens to support the government’s reforms to the safeguard mechanism, but flat-out rejected the party’s calls to ban new coal and gas, saying fossil fuels would continue providing one-fifth of Australia’s energy beyond 2030.

However, the Greens leader, Adam Bandt, claims the party has already made major compromises by offering to pass Labor’s plan through the Senate, saying the party’s request for no new coal and gas was reasonable if the government wanted to address climate change concerns. It potentially sets up more protracted negotiations or Senate gridlock when parliament returns in March.

Vegetable shortages in UK could be ‘tip of iceberg’, says farming union

Energy prices, Brexit and climate crisis mean growers lack confidence to plant crops, says NFU deputy

Shortages of some fresh fruit and vegetables such as tomatoes and cucumbers could be the “tip of the iceberg”, the National Farmers’ Union (NFU) has said.

Certain products are hard to come by in UK supermarkets due to poor weather reducing the harvest in Europe and north Africa, Brexit rules and lower supplies from UK and Dutch producers hit by the jump in energy bills to heat glasshouses.

Boldly not going: zero-travel ‘touring’ play paves the way for eco theatre

Using local creatives and actors, director Katie Mitchell’s A Play for the Living in a Time of Extinction is a narrative response to the climate crisis and an experiment in sustainability

Katie Mitchell’s new theatre production will arrive at the Barbican in London in April having already toured internationally without anyone involved getting on a plane or even crossing a border. The show, entitled A Play for the Living in a Time of Extinction, is an experiment in how theatre can be more sustainable. It is staged by a local creative team and features a different performer in each venue it plays.

The idea took shape at Théâtre Vidy-Lausanne in Switzerland, where the British theatre director was due to stage a show. The French choreographer Jérôme Bel had recently announced that he would no longer fly, a decision Mitchell had herself made after working with scientist Stephen Emmott on Ten Billion, staged at the Royal Court in 2012. Mitchell and Bel began discussions with producers at Vidy-Lausanne about sustainable theatre in which, says Mitchell, “the artistic conversations were intersecting with budgeting and systems and structures as well”. The zero-travel rule is just one part of the initiative which is not a set-in-stone model but rather a way to prompt new ways of working on individual productions and within organisations.

Australia’s big emitters could cut CO2 by 90% by 2050 without offsets, report finds

Report finds that supply chains for major industries, including iron and steel, could cut annual CO2 to 17m tonnes by mid-century

Some of Australia’s largest heavy industrial companies have backed a report that says they could cut direct greenhouse gas emissions in their supply chains by more than 90% by 2050, and not have to rely heavily on carbon offsets.

The report, by the Australian Industry Energy Transitions Initiative (ETI), prepared over three years by Climateworks Centre and the CSIRO, found the industrial transition would cost the equivalent of $21bn a year over three decades if Australia were to play its part in trying to limit global heating to 1.5C.

Climate crisis brings whiff of danger to French perfume capital

In Grasse, droughts, heatwaves, and excessive rainfall have made growing flowers increasingly difficult

When heatwaves used to hit the French town of Grasse, the perfume capital of the world, townspeople didn’t water their flowers. Instead, they marched along the town’s cobblestone streets, in a procession towards the church.

“They were calling for rain from the spirits,” says Carole Biancalana, a fourth-generation perfume flower producer whose grandmother participated in the rain ceremonies. “But I don’t think this procession would cut it in today’s climate.”

Where the parties stand

So the Greens are pushing hard against new coal and gas but have not indicated they are willing to kill off the legislation.

We’re willing to negotiate on everything that we consider will be in keeping with our government’s approach and our election mandate. Nothing more, nothing less. We went to the people seeking a mandate. That’s what we will implement.

Antarctic science expedition put on ice due to problems with Australia’s research vessel Nuyina

Ocean voyage to study declining sea ice levels cancelled after RSV Nuyina required repairs leaving climate scientists dismayed

A major scientific expedition to urgently assess record-low sea ice levels in Antarctica has been cancelled due to ongoing repairs on Australia’s icebreaking vessel, RSV Nuyina, with climate scientists expressing disappointment at “Band-Aid” solutions.

US scientists have this week reported that the floating ice around the continent – which protects melting glaciers from currents and warmer waters – has reached the lowest level ever recorded, in part due to unprecedented heatwaves in recent years.

UAE ‘running towards’ renewable future, says oil boss Cop28 president

Climate groups have accused head of national oil company, Sultan Al Jaber, of conflict of interest

The United Arab Emirates, the oil-rich Gulf nation that is hosting the next UN climate summit, is “running towards” a renewable energy future, the president of the summit has said.

“The UAE has always made progress by getting ahead of the future,” said Sultan Al Jaber, who will oversee the Cop28 conference beginning this November, at an international meeting in Dubai on Tuesday. “We believe that gamechanging solutions can be achieved if the collective political will is there. It certainly is from the UAE. We in the UAE are not shying away from the energy transition. We are running towards it.”
