Snorkelling grandmothers uncover large population of venomous sea snakes in Noumea

Women’s photography of greater sea snake, once believed to be an anomaly in the Baie des Citrons, help scientists understand the ecosystem

A group of snorkelling grandmothers who swim up to 3km five days a week have uncovered a large population of venomous sea snakes in a bay in Noumea where scientists once believed they were rare.

Claire Goiran from the University of New Caledonia and Professor Rick Shine from Australia’s Macquarie University were studying a small harmless species known as the turtle‐headed sea snake located in the Baie des Citrons, but would occasionally encounter the 1.5 metre-long venomous greater sea snake, also known as the olive-headed sea snake.

Former Tuvalu PM says he was ‘stunned’ by Scott Morrison’s behaviour at Pacific Islands Forum

Enele Sopoaga says he was also ‘insulted and deeply angry’ at comments made by Australian deputy prime minister Michael McCormack

The former prime minister of Tuvalu has said he was “stunned” by Scott Morrison’s behaviour at the recent Pacific Islands Forum, which he though communicated the view that Pacific leaders should “take the money … then shut up about climate change”.

Enele Sopoaga, speaking at the national conference of the Australian Council for International Development (Acfid) in Sydney on Wednesday, said Morrison’s behaviour at the forum, which Tuvalu hosted in August, was “dismissive” of the concerns of the Pacific regarding the climate crisis.

Melting glaciers reveal five new islands in the Arctic

Russian navy discovers yet-to-be-named islands previously hidden under glaciers

The Russian navy says it has discovered five new islands revealed by melting glaciers in the remote Arctic.

An expedition in August and September charted the islands, which have yet to be named and were previously hidden under glaciers, said the head of the northern fleet, Vice-Admiral Alexander Moiseyev.

‘There is ingenuity in Africa’: the architect who builds with trash

In the shadow of South Africa’s car industry, making use of discarded parts is a way of life – so Port Elizabeth’s Kevin Kimwelle makes a virtue of it

Tell us: how have South African cities changed in the 25 years after apartheid?

“You’re lucky you arrived on a Monday,” says architect Kevin Kimwelle as we drive through the twisting back streets of Port Elizabeth. “The municipality collects rubbish on a Monday … but later in the week, it’ll be a terrible mess.”

In South Africa waste collection is just one of the services that government struggles to deliver. A little under half of the country (41% of households) is without basic waste collection services, let alone recycling: as a nation, only 10% of waste is recycled, while 90% ends up in landfills.

Lake Chad shrinking? It’s a story that masks serious failures of governance | Oli Brown and Janani Vivekananda

Our two-year study shows the lake has been stable since the 1990s. Costly ‘solutions’ shift focus from the complex causes of the region’s deadly crisis

Lake Chad is a hydrological miracle – a life-giving, freshwater lake in the Sahara desert. But the region around the lake has been engulfed in a violent crisis for more than a decade, which has left nearly 10 million people in urgent need of humanitarian assistance.

Military crackdowns on insurgent groups such as Boko Haram have failed to end the violence. Bringing durable peace to the region requires unpicking a Gordian knot of many interlinked factors: poverty, sectarian mistrust, political marginalisation and corruption. The risks posed by the climate crisis to the rainfall-dependent livelihoods of the people of Lake Chad are an important strand of this challenge.

Shock and gnaw: rat-eating macaques ‘stun’ scientists

Animals act as natural pest control in Malaysia’s vast palm oil plantations, reducing crop losses from rodents

Scientists in Malaysia have said they were “stunned” to discover monkeys regularly killing and eating rats on palm oil plantations, providing a natural anti-pest measure in the country, which is responsible for 30% of the world’s palm oil production.

A report released in Current Biology on Monday, showed that southern pig-tailed macaques, generally thought to eat mainly fruit plus occasionally lizards and birds, foraged for rats on plantations. The authors said that the monkeys’ appetite for rodents showed that rather than being pests, as is commonly believed, the primates’ presence reduced crop losses.

Ocean acidification can cause mass extinctions, fossils reveal

Carbon emissions make sea more acidic, which wiped out 75% of marine species 66m years ago

Ocean acidification can cause the mass extinction of marine life, fossil evidence from 66m years ago has revealed.

A key impact of today’s climate crisis is that seas are again getting more acidic, as they absorb carbon emissions from the burning of coal, oil and gas. Scientists said the latest research is a warning that humanity is risking potential “ecological collapse” in the oceans, which produce half the oxygen we breathe.

Britain now G7’s biggest net importer of CO2 emissions per capita, says ONS

Fall in UK-produced emissions has been offset by those from increase in imported products

Britain has contributed to the global climate emergency by outsourcing its carbon emissions to developing nations, according to official figures, despite managing to weaken the domestic link between fossil fuels and economic growth.

The Office for National Statistics said the UK had become the biggest net importer of carbon dioxide emissions per capita in the G7 group of wealthy nations – outstripping the US and Japan – as a result of buying goods manufactured abroad.

The lost river: Mexicans fight for mighty waterway taken by the US

The Colorado River serves over 35 million Americans before reaching Mexico – but it is dammed at the border, leaving locals on the other side with a dry delta

The temperature is rising toward 45C (113F) as young brothers Daniel and Dilan Rodríguez skip towards a bridge over the Colorado River in the Mexican border town of San Luis Río Colorado. But there is no water flowing through the channel of one of the world’s mightiest waterways. The pair run down the river bank and cheerfully splash through stagnant puddles dotted about the riverbed.

“We wish we had a river, so we could swim, and jump and sail my cousin’s boat,” said Daniel, 12. “At least we have puddles to make mud balls, that can be fun.”

Cook Islands: manager of world’s biggest marine park says she lost job for backing sea mining moratorium

Environmentalist Jacqueline Evans says she was dismissed from the Marae Moana for urging caution on deep-sea mining

The public champion of the world’s largest marine reserve – the Cook Islands’ Marae Moana – has said she lost her job managing it because she supported a moratorium on seabed mining in the Pacific.

Six months ago, Jacqueline Evans won the Goldman Environmental prize – the world’s foremost environmental award – for her work establishing Marae Moana (meaning “sacred ocean”), which covers the Cook Islands’ entire exclusive economic zone of more than 1.9m sq km.

Wahala: trouble in the Niger delta – photo essay

Photographer Robin Hinsch travelled to the Niger delta, visiting the gas flaring sites, artisanal refineries, and meeting the communities living in the hugely polluted environments caused by the oil industry

Covering 70,000 sq km (27,000 sq miles) of wetlands, the Niger delta was formed primarily by sediment deposition. It is home to more than 30 million people and 40 different ethnic groups, making up 7.5% of Nigeria’s total land mass.

Morrison accuses Albanese of ‘throwing tantrums’ – politics live

In Question Time, the prime minister says opposition are addicted to panic and crisis. All the day’s events, live

This is not a sight you will see too often – a LNP senator sitting with the crossbench, against the government.

Susan McDonald chaired the committee that recommended the additional maintenance requirements be removed from charity flight operators – which is what Rex Patrick is calling for.

And from this, I think you can infer from this answer on the voice to parliament, Ken Wyatt has set out that the government will be pushing to legislate, before heading to the referendum

Patricia Karvelas: You do know you’ll break a lot of hearts by not putting the voice to the people?

We also have to be pragmatic and that’s a reality.

Some people have told me it will break their hearts. We have to think about whether we want to be recognised in the Constitution.

Recognition was in section 127 in the Constitution but in the sense of not allowing us to be counted. 127 was struck out.

The 1967 referendum created a number of myths around what it really meant to people. The reality was, was the striking out of that and then the amendment, the 51-26.

I’m going to wait to see what comes out.

I’ve been meeting with people and there is a degree of willingness to have recognition. I think that once we work through whatever the voice is, and that may give us another option.
