Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Biden’s farewell
HEAVY-HEARTED HANDOVER: Outgoing US president Joe Biden used his final televised speech from the Oval Office to issue warnings about climate change and social media disinformation, BBC News reported. The Democrat pointed to “powerful forces” with “unchecked influence” set on “eliminat[ing]” the steps his government had taken to tackle climate change. This came after a separate valedictory address on Monday – covered by NPR – where Biden called on Donald Trump to carry forward his work on climate.
TRUMP LOOMS: Chris Wright – Trump’s pick to head the US Department of Energy – told senators at a confirmation hearing that he would support all forms of energy, including wind and solar power, and that he believed climate change was a “global challenge that we need to solve”, the New York Times reported. This came after the US Supreme Court said it would not hear an appeal from oil and gas companies trying to block climate lawsuits, according to the Associated Press.
Tragedy in Los Angeles
GRIM RECORDS: As the Los Angeles wildfires continue to burn, officials have confirmed that the death toll has risen to 25, the Los Angeles Times reported. Meanwhile, Al Jazeera noted that the Eaton fire is now the “most destructive and deadliest” wildfire in southern California’s history, while the Palisades fire is the “second most destructive”. Carbon Brief covered the causes, impacts and political and media response to the wildfires.
CLIMATE TO BLAME: A rapid attribution study found that climate change was responsible for around 25% of the “fuel” available for the fires, according to CNN. The research – carried out by scientists at the University of California, Los Angeles – said the fires have been “larger and burned hotter than they would have in a world without planet-warming fossil fuel pollution”.
MYTHS SPREAD: As the fires continued to burn, prominent right-wing figures spread “bigoted criticism” about the response to – and cause of – the fires, according to the Guardian, including narratives blaming the fire department’s diversity and inclusion initiatives. France 24 reported that California governor Gavin Newsom accused Elon Musk – leading shareholder of Twitter and Trump confidante – of spreading “lies”.
Around the world
- ZERO MOVEMENT: The Net Zero Asset Managers (NZAM) initiative suspended all activities after investment giant Blackrock withdrew from the voluntary group last week, reported the Times.
- GRID SPLURGE: Bloomberg reported that China State Grid – the nation’s “largest” power network operator – is gearing up to spend a record 650bn yuan ($89bn) this year, as it looks to “keep pace with surging renewable generation”.
- DRIED-UP RIVERS: The Guardian explained how a “historic” drought in Suriname’s interior has dried up rivers, triggered food and water shortages, and disrupted communities’ access to transport, health care and education.
- BP LAYOFFS: The fossil fuel giant BP announced plans to cut 4,700 jobs, or 5% of its workforce, in a bid to “save costs” and “revive” its share price, reported the Financial Times.

Latest climate research
- A study in Geophysical Research Letters found “profound changes” in the seasonal cycle of sea level on the US mid-Atlantic coast. The researchers said that maximum sea level in the area had risen by 82% from 1980-99 to 2000-20.
- Leaks from the Nord Stream gas pipeline in 2022 resulted in the largest amount of methane emitted from a short-term incident on record, according to a new study in Nature.
- A paper in Science Advances found that converting forests into cropland “may be an ineffective climate adaptation strategy for improving nutrition” in Nigeria.

It shows that 85% of authors of the most-mentioned climate papers of 2024 are affiliated with institutions from the global north, whereas only two authors are from Africa. The findings come from Carbon Brief’s full analysis of the 25 most featured climate-related papers of 2024, which was published this week.
Spotlight
‘Cli-fi’ comes of age
Carbon Brief reports on a new literary prize which aims to grow the climate fiction genre.
It is 2025. Wildfires have scorched southern California, while a right-wing US president has been elected on a ticket to axe “wasteful” government programmes.
This is not a summary of recent news headlines, but the setting of Octavia E Butler’s 1993 novel Parable of the Sower, seen by many as an early classic of the climate fiction – or “cli-fi” – genre.
Thirty years after Butler’s prescient tale was published, cli-fi is rising in prominence.
Cli-fi prize
This spring, the inaugural UK Climate Fiction Prize will announce its first winner, awarding £10,000 to a novel that engages with climate change.
Imran Khan, one of the founders of the prize, told Carbon Brief the aim of the prize was to expand a genre that had been growing in recent years. He said:
“We wanted to try to tilt the field in favour of more stories that centre the possibilities of what the future looks like if we start to take climate more seriously – both the good and the bad. We didn’t want it just to be climate dystopias. We wanted to be stories of hope, change and possibility as well.”
The nine books on the longlist make for an eclectic reading list, spanning genres, continents and different planets.
In the mix is the Booker Prize-winning Orbital by Samantha Harvey, a meditation on the beauty and fragility of Earth, told from the vantage point of astronauts circling it. It is facing off against And So I Roar by Abi Daré, which explores themes of climate justice through the eyes of a teenage girl from Nigeria, and The Mars House by Natasha Pulley, a sci-fi novel about the marriage of an Earth refugee and an anti-immigration Martian politician.
Abby Rabinowitz teaches a climate-fiction seminar to dozens of undergraduate engineering students each year at NYU Tandon School of Engineering. She told Carbon Brief that climate fiction had assumed a “more central role in a literary way” since 2018, albeit from a low baseline.
Rabinowitz said she launched the seminar in 2021 after observing that “very few people had dealt seriously with climate change and the climate crisis in fictions, both in literary works and on the screen”. She said:
“The Day After Tomorrow, which came out in 2004, remains the one climate disaster blockbuster that I’m aware of. That was 20 years ago.”
Parable of the Sower is on Rabinowitz’ syllabus, which she said covers “apocalyptic imaginings, speculative fiction storytelling and metaphorical and allegorical treatments of climate change” in books and film. Kim Stanley Robinson’s The Ministry of the Future, Stephen Markley’s The Deluge and Adam McKay’s film Don’t Look Up also feature.
‘Change the story’
There is some debate about whether climate stories inspire action. A 2018 study of US readers found the majority of cli-fi was prompting them to associate climate change with “intensely negative reactions”, which “could prove counterproductive to efforts at environmental engagement”.
However, the research suggests that non-dystopian climate stories with “positive frames” – at the time in shorter supply – might be able to motivate readers to act.
Climate fiction is important, according to Khan, because it can paint a more “vivid” picture of future warming than scientific data, plus “change the story of what is possible”.
Parable of the Sower – which depicts a climate-ravaged world, but also a protagonist with a vision for change – is a case in point, he said:
“It is one of the best examples of… what really good climate fiction can do. It inspires emotions of rage and anger, but also hope and care. Science alone hasn’t solved this issue – and it won’t solve this issue. We need people to care enough to do something.”

The post DeBriefed 17 January 2025: Trump looms; Fossil fuels made LA fires ‘burn hotter’; Has ‘cli-fi’ come of age? appeared first on Carbon Brief.
Mining companies are showcasing new technologies which they say could extract more lithium – a key ingredient for electric vehicle (EV) batteries – from South America’s vast, dry salt flats with lower environmental impacts.
But environmentalists question whether the expensive technology is ready to be rolled out at scale, while scientists warn it could worsen the depletion of scarce freshwater resources in the region and say more research is needed.
The “lithium triangle” – an area spanning Argentina, Bolivia and Chile – holds more than half of the world’s known lithium reserves. Here, lithium is found in salty brine beneath the region’s salt flats, which are among some of the driest places on Earth.
Lithium mining in the region has soared, driven by booming demand to manufacture batteries for EVs and large-scale energy storage.
Mining companies drill into the flats and pump the mineral-rich brine to the surface, where it is left under the sun in giant evaporation pools for 18 months until the lithium is concentrated enough to be extracted.
The technique is relatively cheap but requires vast amounts of land and water. More than 90% of the brine’s original water content is lost to evaporation and freshwater is needed at different stages of the process.
One study suggested that the Atacama Salt Flat in Chile is sinking by up to 2 centimetres a year because lithium-rich brine is being pumped at a faster rate than aquifers are being recharged.

Lithium extraction in the region has led to repeated conflicts with local communities, who fear the impact of the industry on local water supplies and the region’s fragile ecosystem.
The lithium industry’s answer is direct lithium extraction (DLE), a group of technologies that selectively extracts the silvery metal from brine without the need for vast open-air evaporation ponds. DLE, it argues, can reduce both land and water use.
Direct lithium extraction investment is growing
The technology is gaining considerable attention from mining companies, investors and governments as a way to reduce the industry’s environmental impacts while recovering more lithium from brine.
DLE investment is expected to grow at twice the pace of the lithium market at large, according to research firm IDTechX.
There are around a dozen DLE projects at different stages of development across South America. The Chilean government has made it a central pillar of its latest National Lithium Strategy, mandating its use in new mining projects.
Last year, French company Eramet opened Centenario Ratones in northern Argentina, the first plant in the world to attempt to extract lithium solely using DLE.
Eramet’s lithium extraction plant is widely seen as a major test of the technology. “Everyone is on the edge of their seats to see how this progresses,” said Federico Gay, a lithium analyst at Benchmark Mineral Intelligence. “If they prove to be successful, I’m sure more capital will venture into the DLE space,” he said.
More than 70 different technologies are classified as DLE. Brine is still extracted from the salt flats but is separated from the lithium using chemical compounds or sieve-like membranes before being reinjected underground.
DLE techniques have been used commercially since 1996, but only as part of a hybrid model still involving evaporation pools. Of the four plants in production making partial use of DLE, one is in Argentina and three are in China.
Reduced environmental footprint
New-generation DLE technologies have been hailed as “potentially game-changing” for addressing some of the issues of traditional brine extraction.
“DLE could potentially have a transformative impact on lithium production,” the International Lithium Association found in a recent report on the technology.
Firstly, there is no need for evaporation pools – some of which cover an area equivalent to the size of 3,000 football pitches.
“The land impact is minimal, compared to evaporation where it’s huge,” said Gay.
The process is also significantly quicker and increases lithium recovery. Roughly half of the lithium is lost during evaporation, whereas DLE can recover more than 90% of the metal in the brine.
In addition, the brine can be reinjected into the salt flats, although this is a complicated process that needs to be carefully handled to avoid damaging their hydrological balance.
However, Gay said the commissioning of a DLE plant is currently several times more expensive than a traditional lithium brine extraction plant.
“In theory it works, but in practice we only have a few examples,” Gay said. “Most of these companies are promising to break the cost curve and ramp up indefinitely. I think in the next two years it’s time to actually fulfill some of those promises.”
Freshwater concerns
However, concerns over the use of freshwater persist.
Although DLE doesn’t require the evaporation of brine water, it often needs more freshwater to clean or cool equipment.
A 2023 study published in the journal Nature reviewed 57 articles on DLE that analysed freshwater consumption. A quarter of the articles reported significantly higher use of freshwater than conventional lithium brine mining – more than 10 times higher in some cases.
“These volumes of freshwater are not available in the vicinity of [salt flats] and would even pose problems around less-arid geothermal resources,” the study found.
The company tracking energy transition minerals back to the mines
Dan Corkran, a hydrologist at the University of Massachusetts, recently published research showing that the pumping of freshwater from the salt flats had a much higher impact on local wetland ecosystems than the pumping of salty brine. “The two cannot be considered equivalent in a water footprint calculation,” he said, explaining that doing so would “obscure the true impact” of lithium extraction.
Newer DLE processes are “claiming to require little-to-no freshwater”, he added, but the impact of these technologies is yet to be thoroughly analysed.
Dried-up rivers
Last week, Indigenous communities from across South America held a summit to discuss their concerns over ongoing lithium extraction.
The meeting, organised by the Andean Wetlands Alliance, coincided with the 14th International Lithium Seminar, which brought together industry players and politicians from Argentina and beyond.
Indigenous representatives visited the nearby Hombre Muerto Salt Flat, which has borne the brunt of nearly three decades of lithium extraction. Today, a lithium plant there uses a hybrid approach including DLE and evaporation pools.
Local people say the river “dried up” in the years after the mine opened. Corkran’s study linked a 90% reduction in wetland vegetation to the lithium’s plant freshwater extraction.
Pia Marchegiani, of Argentine environmental NGO FARN, said that while DLE is being promoted by companies as a “better” technique for extraction, freshwater use remained unclear. “There are many open questions,” she said.

Stronger regulations
Analysts speaking to Climate Home News have also questioned the commercial readiness of the technology.
Eramet was forced to downgrade its production projections at its DLE plant earlier this year, blaming the late commissioning of a crucial component.
Climate Home News asked Eramet for the water footprint of its DLE plant and whether its calculations excluded brine, but it did not respond.
For Eduardo Gigante, an Argentina-based lithium consultant, DLE is a “very promising technology”. But beyond the hype, it is not yet ready for large-scale deployment, he said.
Strong regulations are needed to ensure that the environmental impact of the lithium rush is taken seriously, Gigante added.
In Argentina alone, there are currently 38 proposals for new lithium mines. At least two-thirds are expected to use DLE. “If you extract a lot of water without control, this is a problem,” said Gigante. “You need strong regulations, a strong government in order to control this.”
