Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Bonn talks wrap up
‘STEEP MOUNTAIN’: As climate negotiations in the German city of Bonn drew to a close on Thursday night, UN climate chief Simon Stiell said that nations had “a very steep mountain to climb” ahead of the COP29 summit in Baku, Azerbaijan, later this year, according to Agence France-Presse.
FINANCE DIVIDE: The talks were marked by “polarised views and sharp disagreements”, the Hindustan Times reported. The divide over climate finance was particularly notable, with countries failing to find common ground, despite the expectation they will come up with a new target “for helping poorer countries cut their emissions and protect their societies in a harsher, hotter world”, Reuters explained.
RAISING AMBITION: In its final daily dispatch from the talks in Bonn, Climate Home News covered an event that saw negotiators from the past, present and future COP presidencies – the UAE, Azerbaijan and Brazil – discuss their efforts to boost the ambition of other countries’ climate plans. All three said they will submit new strategies that are aligned with the Paris Agreement goal of 1.5C, but the article noted that none of them plan to stop producing fossil fuels. Carbon Brief has just published an in-depth article on the key takeaways from Bonn.
Europe goes to the polls
GREEN LOSSES: Losses by Green parties in the European parliamentary elections have “raised concerns” about EU climate policies, the Guardian reported. The Associated Press noted significant Green losses in Germany and France, amid a wider “electoral shift to the right”. Nevertheless, Reuters stated that the EU’s Green Deal package of laws would prove “hard to undo” – a point broadly echoed by experts speaking to Carbon Brief.
UK ELECTION: UK parties began launching their election manifestos. The incumbent Conservatives have drawn criticism for their “pragmatic” net-zero policies, according to the Press Association. By contrast, the Liberal Democrats have pledged to bring the UK’s net-zero goal forward to 2045, BusinessGreen reported. Labour, which polling suggests is likely to form the next government, confirmed its goal to bring forward a target to fully decarbonise the electricity grid from 2035 to 2030, according to Edie. Carbon Brief is tracking where all the parties stand on climate, energy and nature.
Around the world
- DROUGHT RIOTS: Riots have erupted over water shortages in the drought-stricken Algerian city of Tiaret, according to the Associated Press. It described the fossil-fuel-rich nation as being in “among the world’s worst-hit regions by climate change”.
- BAN REVERSAL: New Zealand’s right-wing government has announced it will reverse a ban on oil-and-gas exploration brought in by the previous government, Radio New Zealand reported.
- WET FIRES: A record area of Brazil’s Pantanal wetlands has burned in the first half of 2024, as weak rains have disrupted the usual seasonal flooding, BBC News reported.
- DIRTY MONEY: Sources have told Reuters that Organisation for Economic Co-operation and Development (OECD) members intend to launch a plan to end new private-sector financing for coal projects at the COP29 climate summit.
- REJECT YOUR ELDERS: The Swiss parliament has rejected a European Court of Human Rights ruling, which accused the nation of violating the rights of a group of “female climate elders” by enacting weak climate policies, according to the Guardian.
- TRADE WARS: The EU will impose additional levies on electric cars from China next month, taking tariffs to as high as 48%, Bloomberg said.
$1.1-1.3 trillion
The amount of climate finance developing countries at Bonn want developed countries to provide to them every year, according to Climate Home News.
Latest climate research
- The extreme rainfall that hit Afghanistan, Pakistan and Iran in April and May this year was made twice as likely by El Niño, according to rapid analysis covered by Carbon Brief. The scientists were unable to determine the role of climate change.
- Nitrous oxide emissions from human activities rose by 40% over the past four decades, partly driven by growing global demand for meat and dairy, according to new research reported on by Carbon Brief.
- Exposure to high and low temperatures during pregnancy and the early years of a child’s life “may have lasting impacts” on brain development, according to new research in Nature Climate Change.

Captured

New Carbon Brief analysis by Dr Zeke Hausfather examined when the world is likely to exceed the 1.5C and 2C limits set out in the Paris Agreement. The chart above shows observed global average temperature from 1850 to 2023 in black, along with a vast array of colours illustrating the wide range of possible futures derived from 37 different climate models. This approach suggests that the world will pass 1.5C around the year 2030, with a range of anywhere from 2028 up to 2036.
Spotlight
Fossil fuels, billionaires and weapons: are taxes the solution to climate finance?
Reporting from the UN climate talks in Bonn, Carbon Brief considers proposals to raise much-needed funds for climate action by taxing everything from fossil fuels to bombs.
Developing countries require trillions of dollars to achieve their climate goals and they want developed countries to foot a large chunk of this bill. But, by the most recent count, climate finance from those nations had reached just $116bn in 2022.
In the hunt for climate investment, one option gaining momentum is the idea of new taxes.
Tackling climate change by “making polluters pay” is not a new concept. However, as climate-finance negotiations have stalled at the UN climate talks in Bonn, some provocative ideas have made their way out of NGO reports and into the halls of power.
Tax the rich
Tucked away in the “global stocktake” text that emerged from the COP28 climate summit last year was a reference to “taxation” as an “innovative” source of climate finance.
G20 chair Brazil has taken up this idea, pushing a global “billionaire tax” that could raise around $250bn a year.
Germany and France are among those supporting this tax, arguing it could be a tool to raise climate finance.
COP28 also saw the launch of the International Tax Task Force – a group of countries exploring various levies on fossil fuels, transport and financial transactions.
Speaking to Carbon Brief in Bonn, one of the initiative’s leaders, Ali Mohamed, who is also the African Group chair, said “it’s important that we look at whatever is possible”, given the crises facing the world. He added:
“We hope just to bring together a group of countries that are willing to experiment.”
Some of these ideas are already being discussed at a high level. In particular, negotiators at the UN International Maritime Organisation are considering a shipping-emissions levy.
Oil and bombs
Ahead of Bonn, Bloomberg reported that Azerbaijan, the host of COP29, was considering a new climate fund filled by taxing oil, gas and coal production.
Fossil-fuel levies have already been employed in some countries and have been championed by UN secretary-general António Guterres. Nevertheless, Catherine Abreu, executive director of Destination Zero, told Carbon Brief it is “significant” to see such a fund proposed by the oil-producing COP president. But she added:
“So far, what we’ve heard about Azerbaijan’s proposal makes it sound more like an investment or profit-making scheme than a true climate fund.”
(This idea was further dampened in Bonn by a Politico interview with Yalchin Rafiyev, Azerbaijan’s lead negotiator, in which he suggested that their proposal would not only single out fossil fuel companies – and may consist of voluntary contributions.)
Meanwhile, the Arab Group – led by Saudi Arabia – submitted a proposal at Bonn calling for developed countries to provide $441bn in public spending a year.
Saudi negotiator Mohammad Ayoub went into more detail about how they could achieve this goal, suggesting “a tax on defence companies in developed countries”.
The proposal stood out, not least given Saudi Arabia’s status as the world’s second-largest arms importer. Climate Home News revealed that other taxes proposed by the Arab Group would target “luxury” items, such as fashion and technology.
Iskander Erzini Vernoit, director of the Imal Initiative for Climate and Development, told Carbon Brief the proposal was “a response to the constant refrain, which we hear from the US and others, that there supposedly is not sufficient public finance”.
Tax justice
This all comes against a wider backdrop of calls for “tax justice”. To this end, African nations in particular have been fighting for a new UN Framework Convention on International Tax Cooperation.
“This could potentially lead to global tax measures that might target aviation or international financial transactions,” Teresa Anderson, global climate justice lead at ActionAid, told Carbon Brief.
Taxation is not generally regarded as a vote-winner. Yet, as wealthy countries face pressure to commit public money to climate action, Cat Pettengell, executive director of Climate Action Network UK, said “fair taxes and ending harmful subsidies are there for the taking”.
Watch, read, listen
‘COOKING AND COUGHING’: An on-the-ground report by the Associated Press examined how women are increasingly turning to burning firewood for food preparation in Kenya.
FIRE ERA: The Bloomberg Zero podcast explored how the 21st century could be “shaped by destructive fire weather”.
CLIMATE GRIEF: The Climate Pod spoke to climate justice writer Mary Annaïse Heglar about her new book, Troubled Waters, covering themes of climate racism and grief.

Whale Entanglements in Fishing Gear Surge Off U.S. West Coast During Marine Heatwaves
New research finds that rising ocean temperatures are shrinking cool-water feeding grounds, pushing humpbacks into gear-heavy waters near shore. Scientists say ocean forecasting tool could help fisheries reduce the risk.
Each spring, humpback whales start to feed off the coast of California and Oregon on dense schools of anchovies, sardines and krill—prey sustained by cool, nutrient-rich water that seasonal winds draw up from the deep ocean.

Grasslands and Wetlands Are Being Gobbled Up By Agriculture, Mostly Livestock
A new study takes a first-of-its kind look at how farming converts non-forested areas and major carbon sinks into cropland and pasture.
Agriculture is widely known to be the biggest driver of forest destruction globally, especially in sprawling, high-profile ecosystems like the Amazon rainforest.

Key developments
Food inflation on the rise
DELUGE STRIKES FOOD: Extreme rainfall and flooding across the Mediterranean and north Africa has “battered the winter growing regions that feed Europe…threatening food price rises”, reported the Financial Times. Western France has “endured more than 36 days of continuous rain”, while farmers’ associations in Spain’s Andalusia estimate that “20% of all production has been lost”, it added. Policy expert David Barmes told the paper that the “latest storms were part of a wider pattern of climate shocks feeding into food price inflation”.

NO BEEF: The UK’s beef farmers, meanwhile, “face a double blow” from climate change as “relentless rain forces them to keep cows indoors”, while last summer’s drought hit hay supplies, said another Financial Times article. At the same time, indoor growers in south England described a 60% increase in electricity standing charges as a “ticking timebomb” that could “force them to raise their prices or stop production, which will further fuel food price inflation”, wrote the Guardian.
‘TINDERBOX’ AND TARIFFS: A study, covered by the Guardian, warned that major extreme weather and other “shocks” could “spark social unrest and even food riots in the UK”. Experts cited “chronic” vulnerabilities, including climate change, low incomes, poor farming policy and “fragile” supply chains that have made the UK’s food system a “tinderbox”. A New York Times explainer noted that while trade could once guard against food supply shocks, barriers such as tariffs and export controls – which are being “increasingly” used by politicians – “can shut off that safety valve”.
El Niño looms
NEW ENSO INDEX: Researchers have developed a new index for calculating El Niño, the large-scale climate pattern that influences global weather and causes “billions in damages by bringing floods to some regions and drought to others”, reported CNN. It added that climate change is making it more difficult for scientists to observe El Niño patterns by warming up the entire ocean. The outlet said that with the new metric, “scientists can now see it earlier and our long-range weather forecasts will be improved for it.”
WARMING WARNING: Meanwhile, the US Climate Prediction Center announced that there is a 60% chance of the current La Niña conditions shifting towards a neutral state over the next few months, with an El Niño likely to follow in late spring, according to Reuters. The Vibes, a Malaysian news outlet, quoted a climate scientist saying: “If the El Niño does materialise, it could possibly push 2026 or 2027 as the warmest year on record, replacing 2024.”
CROP IMPACTS: Reuters noted that neutral conditions lead to “more stable weather and potentially better crop yields”. However, the newswire added, an El Niño state would mean “worsening drought conditions and issues for the next growing season” to Australia. El Niño also “typically brings a poor south-west monsoon to India, including droughts”, reported the Hindu’s Business Line. A 2024 guest post for Carbon Brief explained that El Niño is linked to crop failure in south-eastern Africa and south-east Asia.
News and views
- DAM-AG-ES: Several South Korean farmers filed a lawsuit against the country’s state-owned utility company, “seek[ing] financial compensation for climate-related agricultural damages”, reported United Press International. Meanwhile, a national climate change assessment for the Philippines found that the country “lost up to $219bn in agricultural damages from typhoons, floods and droughts” over 2000-10, according to Eco-Business.
- SCORCHED GRASS: South Africa’s Western Cape province is experiencing “one of the worst droughts in living memory”, which is “scorching grass and killing livestock”, said Reuters. The newswire wrote: “In 2015, a drought almost dried up the taps in the city; farmers say this one has been even more brutal than a decade ago.”
- NOUVELLE VEG: New guidelines published under France’s national food, nutrition and climate strategy “urged” citizens to “limit” their meat consumption, reported Euronews. The delayed strategy comes a month after the US government “upended decades of recommendations by touting consumption of red meat and full-fat dairy”, it noted.
- COURTING DISASTER: India’s top green court accepted the findings of a committee that “found no flaws” in greenlighting the Great Nicobar project that “will lead to the felling of a million trees” and translocating corals, reported Mongabay. The court found “no good ground to interfere”, despite “threats to a globally unique biodiversity hotspot” and Indigenous tribes at risk of displacement by the project, wrote Frontline.
- FISH FALLING: A new study found that fish biomass is “falling by 7.2% from as little as 0.1C of warming per decade”, noted the Guardian. While experts also pointed to the role of overfishing in marine life loss, marine ecologist and study lead author Dr Shahar Chaikin told the outlet: “Our research proves exactly what that biological cost [of warming] looks like underwater.”
- TOO HOT FOR COFFEE: According to new analysis by Climate Central, countries where coffee beans are grown “are becoming too hot to cultivate them”, reported the Guardian. The world’s top five coffee-growing countries faced “57 additional days of coffee-harming heat” annually because of climate change, it added.

Nature talks inch forward
This week, Carbon Brief covers the latest round of negotiations under the UN Convention on Biological Diversity (CBD), which occurred in Rome over 16-19 February.
The penultimate set of biodiversity negotiations before October’s Conference of the Parties ended in Rome last week, leaving plenty of unfinished business.
The CBD’s subsidiary body on implementation (SBI) met in the Italian capital for four days to discuss a range of issues, including biodiversity finance and reviewing progress towards the nature targets agreed under the Kunming-Montreal Global Biodiversity Framework (GBF).
However, many of the major sticking points – particularly around finance – will have to wait until later this summer, leaving some observers worried about the capacity for delegates to get through a packed agenda at COP17.
The SBI, along with the subsidiary body on scientific, technical and technological advice (SBSTTA) will both meet in Nairobi, Kenya, later this summer for a final round of talks before COP17 kicks off in Yerevan, Armenia, on 19 October.
Money talks
Finance for nature has long been a sticking point at negotiations under the CBD.
Discussions on a new fund for biodiversity derailed biodiversity talks in Cali, Colombia, in autumn 2024, requiring resumed talks a few months later.
Despite this, finance was barely on the agenda at the SBI meetings in Rome. Delegates discussed three studies on the relationship between debt sustainability and implementation of nature plans, but the more substantive talks are set to take place at the next SBI meeting in Nairobi.
Several parties “highlighted concerns with the imbalance of work” on finance between these SBI talks and the next ones, reported Earth Negotiations Bulletin (ENB).
Lim Li Ching, senior researcher at Third World Network, noted that tensions around finance permeated every aspect of the talks. She told Carbon Brief:
“If you’re talking about the gender plan of action – if there’s little or no financial resources provided to actually put it into practice and implement it, then it’s [just] paper, right? Same with the reporting requirements and obligations.”
Monitoring and reporting
Closely linked to the issue of finance is the obligations of parties to report on their progress towards the goals and targets of the GBF.
Parties do so through the submission of national reports.
Several parties at the talks pointed to a lack of timely funding for driving delays in their reporting, according to ENB.
A note released by the CBD Secretariat in December said that no parties had submitted their national reports yet; by the time of the SBI meetings, only the EU had. It further noted that just 58 parties had submitted their national biodiversity plans, which were initially meant to be published by COP16, in October 2024.
Linda Krueger, director of biodiversity and infrastructure policy at the environmental not-for-profit Nature Conservancy, told Carbon Brief that despite the sparse submissions, parties are “very focused on the national report preparation”. She added:
“Everybody wants to be able to show that we’re on the path and that there still is a pathway to getting to 2030 that’s positive and largely in the right direction.”
