More than 80% of the world’s reefs hit by bleaching after worst global event on record

An ashen pallor and an eerie stillness all that remains where there should fluttering fish and vibrant colours in the reefscape, one conservationist says

The world’s coral reefs have been pushed into “uncharted territory” by the worst global bleaching event on record that has now hit more than 80% of the planet’s reefs, scientists have warned.

Reefs in at least 82 countries and territories have been exposed to enough heat to turn corals white since the global event started in January 2023, the latest data from the US government’s Coral Reef Watch shows.

‘Bordering on incredible’: Coalition under fire for planning to scrap Labor climate policies and offering none of its own

With Peter Dutton’s views on climate change in the spotlight, the focus has turned onto whether there will be any policies to reduce emissions in the next decade

The Coalition is refusing to say if it will introduce any policies to cut Australia’s greenhouse gas emissions in the next decade as it pledges to unwind most climate measures introduced under Labor.

Peter Dutton’s position on the climate crisis came under scrutiny last week after he gave contradictory answers on whether he accepted mainstream climate science. Asked during a leaders’ debate on the ABC whether extreme weather events were worsening, the opposition leader said: “I don’t know because I’m not a scientist”.

Dropping a Labor goal of 82% of electricity coming from renewable generation by 2030 and slowing the roll out of solar and wind farms, in part by scrapping a “rewiring the nation” fund to build new transmission connections. Instead, it says the country would rely on more fossil fuels – coal and gas-fired power – until it could lift a ban on nuclear energy and build taxpayer-owned nuclear generators, mostly after 2040.

Abolishing fines for car companies that do not meet targets to cut the average emissions from the new cars they sell.

Not supporting Labor’s 2030 emissions reduction target. Former diplomats say lowering the target would put Australia in breach of commitments made in the 2015 Paris climate agreement.

Opposing a joint Australia-Pacific bid to host a major UN climate summit in Adelaide next year.

Miliband in blistering attack on Farage’s UK net zero ‘nonsense and lies’

The energy secretary has accused Reform UK’s leader of peddling dangerous falsehoods about renewable power

Tories and Reform use the steel crisis to knock clean energy. They’re wrong: it will secure all our futures

Ed Miliband has torn into Nigel Farage and the Tories for peddling dangerous “nonsense and lies” by suggesting the UK’s net zero target is responsible for destroying Britain’s businesses, including its steel industry.

Cabinet ministers are determined to fight back against the way Reform UK and the Conservatives have unceremoniously lambasted the climate crisis agenda for what they believe are nakedly political reasons before important local elections next month.

The great Mississippi tops list of most endangered rivers amid fears over Trump rollbacks

Cuts to disaster agency and deregulation of fossil fuels, plus rise of water-guzzling datacentres, highlighted in new report

The Trump administration’s sweeping cuts to the federal climate disaster agency – and the full-throttle deregulation of fossil fuels and water-guzzling datacentres – could prove catastrophic for America’s endangered rivers, threatening the food, water and livelihoods of millions of people, according to a new report.

American Rivers’ annual most-endangered rivers list lays bare a myriad of human-made threats including floods, drought and other extreme weather events driven by the climate crisis, as well as industrial pollution and poor river management – all of which Trump’s regulatory rollbacks will almost inevitably make worse.

‘Let Rome burn’: Coalition MP says allowing blackouts the only way to turn voters off renewable energy

Exclusive: Power outages in major cities would help build opposition to climate policies, Colin Boyce tells podcast

The Coalition MP Colin Boyce says he believes the way to turn voters against renewable energy is to “let Rome burn for a while” and allow power blackouts to occur in major cities.

Guardian Australia reported on Wednesday that Boyce had described blackouts as a “big political opportunity” at a meeting of climate science deniers in late 2023.

Deadly floods and storms affected more than 400,000 people in Europe in 2024

European State of the Climate report ‘lays bare’ impact of fossil fuels on continent during its hottest 12 months on record

The home-wrecking storms and floods that swept Europe last year affected 413,000 people, a report has found, as fossil fuel pollution forced the continent to suffer through its hottest year on record.

Dramatic scenes of cars piled up on inundated streets and bridges being ripped away by raging torrents were seen around the continent in 2024, with “high” floods on 30% of the European river network and 12% crossing the “severe” flood threshold, according to the European State of the Climate report.

Palau president backs Australia’s bid to host Cop31 climate summit after Dutton labels it ‘madness’

Surangel Whipps Jr says he would be ‘deeply disappointed’ if attempt were abandoned under Coalition

The president of Palau has delivered a pointed barb at Peter Dutton while strongly backing an Australian bid to host a UN climate conference on behalf of the Pacific, arguing that it would boost regional solidarity and he would be “deeply disappointed” if the attempt was abandoned under the Coalition.

Speaking at a renewable energy conference in Sydney on Wednesday, Surangel Whipps Jr described seeing two-thirds of an island in his archipelago country disappear under water in his lifetime. “For those of us in the Pacific who have lived through storm surges, rising ocean levels and increasingly high tides, the phrase ‘water lapping at our door’ is not a metaphor or a punchline. It’s our fear and reality,” he said.

Space probe to map carbon content of world’s remotest tropical forests

Revolutionary scanner to be fired into Earth orbit this month to measure effects of deforestation

Scientists are about to take part in a revolutionary mission aimed at creating detailed 3D maps of the world’s remotest, densest and darkest tropical forests – from outer space. The feat will be achieved using a special radar scanner that has been fitted to a probe, named Biomass, that will be fired into the Earth’s orbit later this month.

For the next five years, the 1.25-tonne spacecraft will sweep over the tropical rainforests of Africa, Asia and South America and peer through their dense 40m-high ­canopies to study the vegetation that lies beneath. The data collected by Biomass will then be used to create unique 3D maps of forests normally hidden from human sight.

Ningaloo and Great Barrier Reef hit by ‘profoundly distressing’ simultaneous coral bleaching events

Scientists say widespread damage to both world heritage-listed reefs is ‘heartbreaking’ as WA reef accumulates highest amount of heat stress on record

Australia’s two world heritage-listed reefs – Ningaloo on the west coast and the Great Barrier Reef on the east – have been hit simultaneously by coral bleaching that reef experts have called “heartbreaking” and “a profoundly distressing moment”.

Teams of scientists on both coasts have been monitoring and tracking the heat stress and bleaching extending across thousands of kilometres of marine habitat, which is likely to have been driven by global heating.
