Global anger at Sunak’s Cop27 snub that raises fears over UK’s climate crisis stance

PM accused of ‘washing his hands’ of leadership on international climate action with decision not to attend talks

Rishi Sunak’s decision to snub the Cop27 UN climate talks, and to keep King Charles from attending, has angered and upset countries around the world, risking the UK’s standing on the world stage and raising concerns over his government’s commitment to tackling the climate crisis.

Several developing countries told the Guardian of their dismay. Carlos Fuller, Belize’s ambassador to the UN, said: “I can understand why the king was asked not to attend – keeping him out of the fray. However, as the principal UK policymaker and the Cop26 president, the PM should have led the summit.

AFP foil plan to import $1.6bn of liquid meth in coconut water bottles – as it happened

Chalmers on the size of government debt and making it ‘sustainable’

The treasurer is asked whether the government will consider rethinking taxes like GST and PRRT.

We have already found $22bn in savings, $28.5bn in budget improvements overall. We kept real spending growth flat across the forward estimates. We have got the debt down over the forward estimates. We have let 99% of the temporary revenue surge from higher commodity prices flow through to the budget.

That is good progress when we have shown in doing that … you can move sensibly on all fronts, restraint, trimming spending, sensible tax reform, you can make the budget more sustainable and that will be the task of the two or three budgets remaining in this parliamentary term as well.

We need to work out how do we maintain a focus on Australians with a disability and their families, how do we put them front and centre, and at the same time make sure that spending on the NDIS is sustainable and important part of that is making sure we get value for money for every dollar that is spent in what is a really important, really, really important service that we provide to Australians.

I do understand there is a substantial part of the community that would prefer that that PRRT take was higher.

We haven’t been working up an option to do that to change the PRRT arrangements but the treasury has been commissioned by my predecessor and by his predecessor to do some of this work around the taxing point in the PRRT.

We do want to make sure Australians get a good return for their resources. We need to balance that against the investment that’s been made into the sector. When I get that advice from I will engage in it a meaningful way and I will listen to it.

We have seen I think as you acknowledged in your first question, on this topic, company taxes are up quite substantially. That’s a good thing and we have let that flow through to the budget. The PRRT, there’s a modest increase. I will wait to see what the treasury advises us on the conclusion of the review that my two predecessors put in place.

Thin fish, small catches: can Japan’s sushi culture survive climate crisis?

Global heating is warming waters, changing salmon and tuna migration – and hurting fisheries

There is little at Shiogama seafood market to suggest that Japanese consumers could one day be deprived of their favourite seafood – from giant crab’s legs simmering in a winter nabe hotpot to spheres of salmon roe resting on a bed of rice wrapped in nori seaweed.

Stalls heave with huge sides of bluefin tuna, expertly transformed into more manageable portions by knife-wielding workers, while early-morning shoppers pause to inspect boxes of squid, flounder and sea pineapples landed only hours earlier.

Goal of limiting global heating to 1.5C ‘more fragile’ than ever, says Cop27 chair

Exclusive: in a rare interview, Egyptian minister Sameh Shoukry says global tensions are making talks harder

Windfall tax must change in face of ‘excessive’ oil profits – Cop26 chief

The goal of limiting global heating to 1.5C is “more fragile” than ever, as world leaders prepare to meet for crucial climate talks, the president-designate of the negotiations has warned.

Sameh Shoukry, the foreign minister of Egypt, who will chair the UN Cop27 climate summit next month, said in a rare interview that forging agreement would be harder than at any other recent climate talks, owing to the “turbulent” global economy and “difficult” geopolitical tensions, stoked by the Ukraine war.

Parks director should be accountable for ‘offence’ to Kakadu sacred site, protection authority says

AAPA seeks leave to appeal against NT supreme court decision that found director is exempt from prosecution under state’s laws

A fight to hold Parks Australia to account over a walking track built through a sacred site in the Kakadu national park could be heading to the high court after a lower court found a Northern Territory law did not apply to the federal organisation.

The Aboriginal Areas Protection Authority (AAPA) has sought leave to appeal against a decision by the NT supreme court in September which found the director of Parks Australia was exempt from prosecution under the NT Aboriginal Sacred Sites Act.

Shrew-like creature was placental mammals’ last common ancestor

Group’s earliest primogenitor was probably a diminutive creature with a long snout, researchers suggest

The last common ancestor of today’s placental mammals – a group that includes humans, whales and armadillos – was probably a shrew-like creature with a long snout, researchers have revealed.

The forerunners of mammals are believed to have split from what eventually became reptiles around 320m years ago, but it was not until some time between 70 and 80m years ago that placental mammals arose.

Climate crisis funds not reaching countries in need, senior UN official says

With famine in Somalia almost inevitable, Martin Griffiths criticises opaque handling of $100bn a year promised to poorer countries

The UN’s humanitarian chief has questioned why billions of dollars pledged to tackle the climate crisis have not been used to fight famine in Somalia.

Martin Griffiths said he did not know where the promised $100bn (£87bn) a year to fight the impact of global heating in poorer countries had gone, and called for greater transparency around climate finance.

‘Monstrous’ east African oil project will emit vast amounts of carbon, data shows

Experts say crude oil pipeline from Uganda to Tanzania will produce 25 times host nations’ combined annual emissions

An oil pipeline under construction in east Africa will produce vast amounts of carbon dioxide, according to new analysis. The project will result in 379m tonnes of climate-heating pollution, according to an expert assessment, more than 25 times the combined annual emissions of Uganda and Tanzania, the host nations.

The East African crude oil pipeline (EACOP) will transport oil drilled in a biodiverse national park in Uganda more than 870 miles to a port in Tanzania for export. The main backers of the multibillion dollar project are the French oil company TotalEnergies and the China National Offshore Oil Corporation (CNOOC).

Researchers reveal secret of aye-ayes’ long middle finger

Video shows captive Madagascan primates using elongated finger to pick nose and eat the mucus

With its big eyes, bushy tail and sensitive ears, the aye-aye may appear a cute, if quirky, creature. But now researchers have discovered it has a less endearing trait: it uses its long middle finger to pick its nose – and eat the mucus.

Aye-ayes are – like humans – primates, but they are nocturnal, endangered and only found in Madagascar. An object of superstition, they have a number of unusual features, including rodent-like teeth and a skinny, elongated finger with a ball-and-socket joint.
