Key developments

Europe focuses on biodiversity

‘WORSE THAN TERRORISM’: Climate change and biodiversity loss pose a more “fundamental threat” to the UK than terrorism or Vladimir Putin, UK foreign secretary David Lammy said in his first major policy address, the Independent reported. Giving a speech at London’s Kew Gardens, Lammy said that climate change and biodiversity loss “may not feel as urgent as a terrorist or an imperialist autocrat”, but they are “more fundamental…systemic…pervasive…and accelerating towards us”, the Independent said. The Financial Times said that Lammy pledged that climate change and biodiversity loss would be “central to all the Foreign Office does”, and that he will create “special representatives” in each area. The Guardian noted this will be the first time the UK has appointed a special envoy for nature.

RISE OF RIBERA: Elsewhere, Teresa Ribera, Spain’s ecological transition minister, has been appointed as EU commissioner Ursula von der Leyen’s second-in-command, with a “vast portfolio” including climate and competition policy, Politico reported. The Guardian said that the “outspoken” Ribera is to become one of six vice-presidents in the incoming EU executive led by von der Leyen, which is expected to start work at the end of the year. Euronews said that green activists have “breathed a sigh of relief” at the appointment.

AGRICULTURE COMMISSIONER: Von der Leyen has also appointed a new agricultural commissioner in Christophe Hansen, a Luxembourg MP from the centre-right Christian Social People’s party, the Irish Independent reported. According to the newspaper, von der Leyen has given Hansen “100 days to prepare a vision for the EU agriculture and food sectors”, tasking him with ensuring they are both competitive and “within the boundaries of our planet”. Portuguese news agency Lusa said that Portuguese farmers have “high expectations” that Hansen will prioritise the needs of agricultural workers. Elsewhere, DeSmog has mapped “Ireland’s powerful farming lobby”.

Australia’s deforestation hotspots

OUTLIERS: A new report from the environment and heritage department of the New South Wales government found that more than 45,000 hectares of native vegetation were cleared in 2022 to make way for farming, infrastructure and other projects. Nathaniel Pelle, a campaigner with the Australian Conservation Foundation, told the Sydney Morning Herald that Australia is an “outlier among wealthy countries for forest loss”. He added: “Europe has been historically cleared, Canada has been historically cleared, the US and Australia have been historically cleared, but what separates us from them is that we’re still doing it.” Deforestation in the state is “among [the] worst in the world”, the newspaper wrote.

‘ZOMBIE INDUSTRY’: The report showed that land clearing has been on the rise since 2015, when the previous government announced upcoming changes to its land-clearing laws, the outlet said. In a separate article, the Sydney Morning Herald called logging in the neighbouring state of Victoria the “‘zombie’ industry that won’t die”. According to the newspaper, “commercial logging officially ended” on 1 January, but timber mills “continue to process native hardwood timbers” – sourced from private landowners and from the government’s “fuel-reduction” wildfire-prevention strategies. The outlet wrote: “Environment groups say logging is now taking place without proper planning or oversight, leaving threatened species at risk.”

EPA ON THE AGENDA: Despite promises to “develop new nature legislation” and put nature “back on the priority list”, Australia’s Labor government – elected in May 2022 – “has not lived up to…early rhetoric” around nature protection, Adam Morton wrote in a column for the Guardian. Morton noted that the push to create a national environment agency, Environment Protection Australia, “look[s] to be in trouble”, as deals with either the Greens or the Coalition look unlikely. Writing in the Conversation, environmental-law expert Dr Justine Bell-James said: “All this is bad news for our threatened species and sick ecosystems. We know what needs to be done. But our government is showing worrying signs of letting industry and developers control their environmental agenda.”

Spotlight

Humans and polar bears collide at Earth’s Arctic research hub 

In this spotlight, Carbon Brief reports from the Earth’s most-northerly human settlement, which is increasingly facing polar bear encounters amid rapid Arctic change.

Ask anyone living and working in Ny-Ålesund – the Earth’s most northern human settlement, located on the Norwegian archipelago of Svalbard in the Arctic Ocean – what they perceive to be the number one threat to their safety and they will each offer the same answer: polar bears.

A little more than 1,200km from the North Pole, the tiny Arctic town of Ny-Ålesund started life as a coal mining district in the early 20th century, but today operates solely as an international climate research hub, hosting about 60 scientists at its busiest time in the summer months.

The vast Arctic wilderness surrounding the town is home to one of the world’s largest permanent polar bear populations. 

Protective measures

Ever since Ny-Ålesund’s inception, the company running logistics in the town has implemented strict protocols with the aim of protecting people from polar bears.

The few roads leading out of town are marked with polar bear hazard signs. Nearly every communal building in the town carries posters with instructions of what to do in the event of a polar bear sighting.

When researchers go out into the field to carry out their research, at least one of them must act as a “polar bear guard” – meaning they need to pass shooting practice and carry a rifle in case they need to kill a bear in an emergency.

“We are entering a habitat that is not ours,” Dorothea Moser, an ice cores researcher with the British Antarctic Survey, the UK’s polar research institute, told Carbon Brief. “With polar bear protection, we’re trying to protect both us as researchers and the polar bear.”

As part of the protective measures when out in the field, guards carry binoculars and constantly scan the environment around them. If they spot a bear on the horizon, the research team will immediately leave the area and notify the town.

If a polar bear is spotted within contact distance – the animals can run at speeds up to 25 miles per hour – then researchers will let off a flare in an attempt to scare it away.

“We can defend ourselves with flares, we’re scaring away the polar bear and creating more space between us in a defensive way,” Moser added. “Of course, we also have to carry a weapon, but we hope that we never have to use it. In the past 30 years, we have not had any lethal encounters.”

Rapid change

These strict measures have protected both scientists and bears for decades in Ny-Ålesund, but rapid change in the region could threaten this delicate balance.

Svalbard bears were nearly hunted to extinction in the 20th century. However, a ban was put in place in 1973, which saw numbers recover. Now, the Beaufort Sea subpopulation, which includes Svalbard bears, is considered “stable”.

However, climate change is causing Svalbard’s environment to shift rapidly, with temperatures rising seven times faster than the global average.

Rapid warming has had a devastating impact on sea ice, which blankets the Arctic Ocean in the cooler winter months before shrinking back at the height of summer. As the Earth warms, the extent of the sea ice in summer is becoming smaller every year.

This is a problem for polar bears, which use sea ice to hunt seals, their main source of prey. Research has found that the disappearance of sea ice is forcing bears to search further afield for food, sometimes bringing them closer towards human settlements.

Ingrid Kjerstad, research coordinator at the Norwegian Polar Institute in Ny-Ålesund, which oversees all scientific research in the town, told Carbon Brief that their records show the number of polar bears coming into contact with humans in the region has increased in recent years.

An increase in human-bear encounters is a worry for both researchers and wildlife. Although scientists in Ny-Ålesund have avoided shooting a bear, there have been several lethal incidents involving both human and animal fatalities in Svalbard’s capital of Longyearbyen.

The evidence of more human-bear encounters in Ny-Ålesund is still “anecdotal” and has not yet been published in a peer-reviewed science journal, Kjerstad added, but is yet another sign of how rapid environmental change is transforming life at Earth’s northern edge. 

News and views

BIODIVERSITY FINANCE: Funding to help developing nations address biodiversity loss grew by more than $4bn in 2022, but mostly in the form of loans, rather than grants, according to new figures from the Organisation for Economic Cooperation and Development (OECD) reported by Climate Home News. The OECD report, which analysed the period from 2015 to 2022, showed that biodiversity funding grew from $11.1bn in 2021 to $15.4bn in 2022. Climate Home News added that the increase came largely from multilateral institutions – mainly development banks – which increased their funding from $2.7bn in 2021 to $5.7bn in 2022, “mostly by offering concessional loans, which are cheaper than borrowing on commercial terms”.

DAM IT: Dams around the world will struggle to cope with increasingly common severe rainfall, “leading to an increased likelihood of failure and risk of catastrophic flooding”, according to two researchers at the IHE Delft Institute for Water Education. They added that “it is not clear what climate and hydrological data was used to design” most of the world’s dams and spillways. Covering the IHE Delft commentary, Sudanese outlet Dabanga wrote that, due to a lack of preventative maintenance, the Jebel Aulia dam south of Khartoum “may lead to a failed agricultural season” this winter. It added: “A collapse of the dam also threatens people in Khartoum.”

CALI INCOMING: The COP16 nature summit will be a key “political moment and a very important moment for biodiversity”, UN biodiversity chief Astrid Schomaker told a press conference on 23 September. Unlike the previous summit, a number of high-profile politicians are due to attend the upcoming talks in Cali, Colombia – including Brazilian president Luiz Inácio Lula da Silva and Mexico’s president-elect, Dr Claudia Sheinbaum. There will also be a “very strong presence” of Indigenous peoples at the talks, Colombia’s environment minister, Susana Muhamad, told the press briefing. Muhamad also called on richer countries to put more money into the dedicated fund to support biodiversity goals. Meanwhile, Carbon Brief has updated its interactive tracker of national biodiversity strategies and action plans to include new submissions.

ECOCIDE RECOGNITION: Vanuatu has renewed its push to recognise “ecocide” – “the severe and reckless destruction of nature” – under the Rome Statute of the International Criminal Court, the Pacific Island News Association reported. The Pacific nation first proposed the addition of ecocide in 2019, the news outlet said, and its bid received a boost from a 2021 independent expert report that “outlined the legal framework for ecocide”. The article quoted Vanuatu’s UN ambassador, Odo Tevi, who said that existing laws protecting nature “are insufficient” and that the definition should “focu[s] on the severity of the outcome rather than specific prohibited behaviours”.

SHAPE UP OR SHIP OUT: Drought in South America is forcing grain shippers “to look for alternatives” as the water level on the Paraná River has dropped precipitously, the Argentine trade publication ArgenPorts reported. Argentine officials noted that while water levels are far below normal at present, the effects of the drought “will not be as cruel and harsh as the one that occurred from 2020 to 2022”. Elsewhere, the “unprecedented drought” in Ecuador has led to “mass power cuts”, forest fires and the declaration of a “red alert” in several parts of the country, according to MercoPress.

Watch, read, listen

FOOD FOR THOUGHT: In Scientific American, science historian Prof Naomi Oreskes argued that the Svalbard Global Seed Vault “illustrate[s] why we need to prevent climate disaster rather than plan for it”.

HISTORY REPEATS: Nigeria’s the Cable examined how a burst dam that displaced 400,000 people in Borno state 30 years ago has flooded once again amid extreme rainfall in the country.

CONTINUED STRUGGLE: Despite legal wins across the world, Indigenous peoples still face evictions from their lands and struggle to obtain the reparations promised to them, a Mongabay investigation found.

PESTICIDE LOOPHOLE: An investigation by Unearthed alleged that companies are exploiting loopholes in France’s landmark pesticide ban to ship growing amounts of harmful chemicals overseas.

New science

• Extreme permafrost thaw could lead to a “rapid intensification” of wildfires in western Siberia and Canada, said research in Nature Communications. Using a wide range of climate simulations, the study found that warming-driven rapid permafrost thaw could lead to “massive soil drying, surface warming and reduction of relative humidity”, which could in turn boost fires.
• Prioritising boosting carbon stores on agricultural land could draw down as much CO2 as global tree-planting by 2050 and provide farmers with hundreds of billions of dollars in economic benefits, a new Nature Food study found. The authors used an economic land-use model to project how boosting carbon in agriculture could benefit producers and the planet.
• New research in Environmental Research Letters found that the number of heatwave days affecting global cropland will increase nearly 4.5-fold by the end of the century under a medium-emissions scenario. Using observational data and climate models, researchers found “consistent increases” in the frequency and intensity of heatwaves affecting croplands in the future.
