Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Africa’s second climate summit
‘NOT CHARITY’: At the second Africa climate summit held in Addis Ababa in Ethiopia this week, leaders “chastised developed nations for failing to honor [climate finance] pledges” and said they will “tap the private sector” to help fill the gap, Bloomberg reported. In a joint statement, African leaders said that providing climate finance is “a legal obligation and not charity, as anchored in the UN Framework Convention on Climate Change and its Paris Agreement”, according to the outlet.
SOLUTIONS CENTRED: Climate Home News reported that Ethiopian president Taye Atske Selassie told the closing ceremony on Wednesday the summit had repositioned Africa “not as victims of a crisis it never created but as a global centre for climate solution, renewable energy and green growth”. The outlet added that the joint leaders’ declaration called for “strengthened and sustained support” to scale up African-led climate initiatives, such as the 8,000km Great Green Wall across the Sahel and the African Forest Landscape Restoration Initiative.
Around the world
- ‘SILLY’: Chris Wright, the climate-sceptic US energy secretary, has dismissed the impacts of climate change as “not incredibly important” and described the Paris Agreement as “silly”, reported the New York Times. Elsewhere, the group of “climate contrarians” behind Trump’s misleading climate report have been “disbanded” following a lawsuit challenging their appointment, CNN reported.
- CHINA BOOM: The world’s fossil-fuel use could begin to drop by 2030 as a result of China’s “rapid adoption of renewables and its increasing reliance on electricity”, Bloomberg reported, citing a new study by thinktank Ember.
- NDC INDECISION: EU member states are still “wrangling” over the bloc’s overdue 2035 climate target, “with no sign of agreement”, according to a leaked draft text seen by the Guardian.
- TRADE SPOTLIGHT: Brazil plans to propose a new forum for governments to discuss how climate policy affects trade at the next World Trade Organization meeting next week, according to Reuters.
- UK PUBLIC POLLED: In a frontpage story, the Times covered new polling it commissioned, reporting that the number of people who think the dangers of global warming are exaggerated has increased by more than 50% in the past four years, from 16% to 25%. [Polling experts have criticised the framing of the Times coverage, noting that a large majority of the public still back net-zero.]
£797 million
The record amount of UK climate aid spent on nature last year – largely due to an increase in spending on carbon offsets, according to new Carbon Brief analysis.

Captured
A new study used “extreme event attribution” to assess the impact of climate change on all 21st-century heatwaves that were classified as “major disasters”. It found that global warming linked to the world’s biggest 180 oil and gas companies made all 213 heatwaves analysed more intense and frequent. Meanwhile, one-quarter of the heatwaves would have been “virtually impossible” without human-caused global warming. The paper, covered by Carbon Brief, analysed 213 heatwaves over 2000-23 that were recorded in the EM-DAT database of “major disasters” . These heatwaves are shown in the map above.

How scientists can tackle net-zero backlash
This week, Carbon Brief asks climate scientists attending a summit at the University of East Anglia, UK how researchers can better combat net-zero misinformation.
It comes as the UK’s right-wing political parties and press are increasingly making misleading claims about net-zero.
Asher Minns, executive director of the Tyndall Centre for Climate Change Research at the University of East Anglia
The whole discourse around net-zero has become something that it was never intended to be. It’s a quite specific scientific concept that came out of the IPCC 1.5C report, following up on [the] Paris [Agreement], so it actually has quite a specific definition, but it has actually become a phrase that is being used really just to mean “removing CO2” or “saving energy”, even. It’s become this kind of huge term across public, across media, across policy, that everybody can just pin what they mean to “net-zero” without actually referring to what it actually is, which is absolute zero emissions, getting CO2 out of the atmosphere. The fact that there is a government department called “net-zero” isn’t great for that public discourse, for public understanding, and that’s why we’ve got a bit of a backlash. I don’t think we need to necessarily abandon the phrase net-zero, but I think we should just talk about clean energy and concepts that people have a chance of hanging onto, rather than something that’s really quite difficult.
Prof Corinne Le Quéré, Royal Society research professor of climate change science at the University of East Anglia
I think narratives about the way that we present climate action can be very negative, and, in fact, we do climate action all the time. We’ve cut emissions by half in the UK and most people haven’t realised that this is happening. Just talking about climate change in the way that there are things that you can do that are desirable and have benefits for you. Of course, the government needs to make climate solutions accessible to everybody. But improving the narratives about how we talk about climate change, that would be, for me, a small thing that we could do.
Prof Hayley Fowler, professor of climate change impacts at Newcastle University
I don’t think we can do it alone. I think we try to do everything alone and I don’t think that’s the right approach. My personal opinion is we need to be collaborating with key influencers and celebrities, quite honestly, who can actually get that message across to the people who need to hear that message. I think we need probably a few key spokespeople. And I don’t think they should be scientists, but they should have simple and clear scientific messages that they convey. There’s lots of misinformation and it’s conveyed in very clear ways with simple messaging. Often climate science is really, really complicated and that’s why people just don’t understand it, they don’t understand the jargon surrounding it and, therefore, perhaps they are more likely to understand the simple messages that come from the climate deniers.
Dr Ruth Wood, senior lecturer in environment and climate change at the University of Manchester
I find it quite challenging to work out how to engage in those discussions because they’re taking place in forums that I’m not at. Do we need a groundswell of voices around supporting net-zero, which have the same level of media savviness of the anti net-zero groups? If we had their same ability to mobilise and get the message out there, maybe that would counter some of their narratives. The gap between science and communication is a huge challenge.
Prof Charlie Wilson, professor of energy and climate change and senior research fellow in the Environmental Change Institute at the University of Oxford
I guess that part of the answer is how we’ve always done it, which is forceful rebuttals and corrections with appropriate evidence. The second bit is like learning how the algorithms work to promote both information, as well as misinformation. This misinformation is being amplified by algorithmic preferences expressed through social media platforms, which emphasise juicy clickbait-type stuff.

Sydney, Thursday 19 March 2026 — In response to escalating attacks on gas fields in the Middle East, including Israeli strikes on Iran’s giant South Pars gas field and Iranian retaliations on gas fields in Qatar and Saudi Arabia, the following lines can be attributed to Solaye Snider, Campaigner at Greenpeace Australia Pacific:
“The targeting of gas fields across the Middle East is a perilous escalation that reinforces just how vulnerable our fossil-fuelled world really is.
“Oil and gas have long been used as tools of power and coercion by authoritarian regimes. They cause climate chaos and environmental pollution and they drive conflict and war. The energy security of every nation still hooked on gas, including Australia, is under direct threat.
“For countries that are reliant on gas imports, like Sri Lanka, Pakistan and South Korea, this crisis is just getting started. It can take months to restart a gas export facility once it is shut down, meaning the shockwaves of these strikes will be felt for a long time to come.
“It is a gross and tragic injustice that while civilians are killed and lose their homes to this escalating violence, and families struggle with a tightening cost-of-living, gas giants like Woodside and Santos have seen their share prices surge on the prospect of windfall war profits.
“We must break this cycle. Transitioning to local renewable energy is the way to protect Australian households from the inherent volatility of fossil fuels like gas.”

Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Iran war fallout continues
WORK FROM HOME: The International Energy Agency has advised its member countries to take 10 steps in response to the ongoing energy crisis fuelled by the Iran war, including reducing highway speeds and encouraging people to work from home, said the Guardian. It came after retaliatory attacks between Israel and Iran continued to destroy energy infrastructure in the Middle East, causing energy prices to soar further, said Reuters.
SUPPLY DISRUPTED: The IEA also said it is prepared to make more of its member nations’ 1.4bn-barrel oil reserves available to help ease the impacts of what it called the “biggest supply disruption in the history of the oil market”, reported Bloomberg. The outlet noted that Asian countries have been hit hardest by the shortages, caused by a “near-halt” of shipping through the Strait of Hormuz.
EU SUMMIT: The energy crisis dominated talks at an EU leaders summit on Thursday, said Politico. Arriving at the summit, Spain’s prime minister Pedro Sánchez attacked other European leaders for using the energy crisis as an excuse to “gut climate policies”, according to the EU Observer. The Financial Times said that some European leaders have asked the European Commission to overhaul its flagship emissions trading system (ETS) by summer in response to the energy crisis.
COAL BOOST: In response to the conflict, utility companies in Asia are “boosting coal-fired power generation to cut costs and safeguard energy supply”, said Reuters. UN climate change executive secretary Simon Stiell told Reuters: “If there was ever a moment to accelerate that energy transition, breaking dependencies which have shackled economies, this is the time.”
Around the world
- WINDFARM WINDFALL: The Trump administration in the US is considering a nearly $1bn settlement with TotalEnergies to cancel the French energy company’s two planned windfarms off the US east coast and have it instead invest in fossil-gas infrastructure in Texas, according to documents seen by the New York Times.
- BUSINESS CLASH: Following “clashes” with the agribusiness sector, Brazil launched its new climate plan, which calls for a 49-58% reduction in greenhouse gas emissions from 2022 levels by 2025 and includes “specific guidelines for different sectors”, reported Folha de Sao Paolo.
- SALES SLUMP: Sales of liquified petroleum gas from India’s state-run oil companies have fallen by 17% this month due to cuts in deliveries to commercial and industrial consumers “amid the widespread logistical bottlenecks triggered by the Iran war”, said the Economic Times.
- CUBAN ENERGY CRISIS: The US imposed an “effective oil blockade” on Cuba, leaving the country facing its “worst energy crisis in decades”, reported the Washington Post. Meanwhile, Chinese exports of solar panels to the island have “skyrocketed” since 2023, it added.
- RECORD HIGHS: An “unprecedented” heatwave in the western and south-western US is “shattering dozens of temperature records” and could lead to drought in California in the coming months, reported the Los Angeles Times.
- VULNERABILITY CONCERNS: Landslides that killed more than 100 people in southern Ethiopia have “renewed concerns about Ethiopia’s vulnerability to climate-related disasters”, said the Addis Standard.

Captured
Carbon Brief this week published a significant update to its map of how climate change is affecting extreme weather events around the world. The map now includes 232 new extreme weather events from studies published in 2024 and 2025. Of these events, 196 were made more severe or more likely to occur by human-driven climate change, 12 were made less severe or less likely to occur and 10 had no discernible human influence. (The remaining 14 studies were inconclusive.)

New Zealand breaks new ground on climate litigation
This week, Carbon Brief speaks to experts about a first-of-its-kind climate lawsuit in New Zealand.
Earlier this week, representatives from two environmentally focused legal advocacy groups challenged the New Zealand government’s climate-action plan in court.
The plaintiffs argued that the measures laid out in the plan are insufficient to achieve the country’s legal obligation to hold global warming to 1.5C above pre-industrial temperatures.
The case could be “influential” in shaping lawsuits and rulings around the world, one legal expert not involved in the case told Carbon Brief.
Reductions vs removals
The new case contends that there are several issues regarding the New Zealand government’s response to climate change.
One of the key arguments the plaintiffs make is that New Zealand’s second emissions reduction plan, which covers the period from 2026-30, is overreliant on the use of tree-planting to achieve its targets.
When the plan was released in December 2024, it was “immediately clear that it was a pretty lacklustre plan”, Eliza Prestidge Oldfield, senior legal researcher at the Environmental Law Initiative, one of the groups behind the legal case, told Carbon Brief.
The plan called for large-scale planting of pine tree plantations, which are not native to New Zealand and have a high risk of burning. Because of this, there are concerns about how permanent any carbon removal provided by these plantations actually can be, experts told Carbon Brief.
Catherine Higham, senior policy fellow at the Grantham Research Institute on Climate Change and the Environment who was not involved in the case, said:
“The lawyers are arguing that there are real challenges with equating the emissions that you may be able to remove from the atmosphere through afforestation with actual emissions reductions, which are much more certain.”
‘Global dialogue’
While other climate lawsuits elsewhere in the world have also focused on the inadequacy of a government’s plan to meet its stated emissions-reduction targets, this is the first such case that addresses the role of removals head-on.
Lucy Maxwell, co-director of the Climate Litigation Network, told Carbon Brief that the lawsuit “builds on a decade of climate litigation” in national, regional and international courts.
Maxwell, who was not involved in the New Zealand case, added that there is a “real global dialogue” between, not just plaintiffs, but national courts as well. She said:
“[National courts] look to common issues that have been decided in other countries. They’re not binding on that court if it’s at the national level, but they are influential.”
Given that many other countries have legal frameworks requiring their governments to create plans outlining the pathway to their long-term climate targets, Prestidge Oldfield told Carbon Brief that other jurisdictions “should be interested in these questions around the level of certainty”.
Higham noted that, even if the case is successful, addressing the plan’s shortfalls will face its own set of challenges. She told Carbon Brief:
“A lot of these decisions are political and they can be politically contentious…Those [measures] have to be put into action through legislation and that is then subject to the usual political process. So that’s where the challenge comes in.”
While she could not speculate on the outcome of the case, Prestidge Oldfield said it was “very heartening” to see that both the judge and the opposing counsel “appreciated how much of a concern climate change is globally”.
She added:
“It’s not a given that the judge would even be interested in climate change.”

Around 300 scientists, civil servants, journalists and climate experts took part in the 11th annual Carbon Brief quiz on Wednesday 18 March 2026.
For the second time, this year’s quiz was hosted by Octopus Energy at its headquarters in central London.
In total, 39 teams participated – 25 teams in person and 14 teams joining via Zoom.
Competing teams reflected a wide range of climate change and energy professionals. The list included journalists, civil servants, climate campaigners, policy advisers, energy experts and scientists.
Organisations represented included: Council on Energy, Environment and Water (CEEW) in India; New Scientist; the Times; Business Green; the Bartlett School of Environment, Energy and Resources (BSEER), UCL; Verisk Maplecroft; BBC; World Weather Attribution; Grantham Institute at Imperial; DESNZ; WWF; European Climate Foundation (ECF); the ENDS Report; C40 Cities; Ricardo; Met Office; Meliore; E3G; Danish Meteorological Institute (DMI); Energy Transitions Commission; Carbon Tracker; Ember; Royal Meteorological Society; Civil Service Climate and Environment Network (CSCEN); Changing Markets Foundation; Cerulogy; Oxford Sustainable Law Programme; Université de Lausanne; University of Exeter; Centre for Environment and Sustainability, University of Surrey; UK Parliament; Skeptical Science; ECIU (Energy and Climate Intelligence Unit); Octopus Energy; DeSmog; Department for Transport and Royal School of Mines.
Teams were tested with five rounds of questions – general knowledge, policy, science and two picture rounds. (See the slideshow of the questions and answers below).
After two hours of playing, this year’s winners were announced.
Comprised of players from the Council on Energy, Environment and Water (CEEW) in India, last time’s second place team, “Emissions Impossible” won the coveted Carbon Brief trophy with a total score of 76 out of 100 available points.
In joint second place, with 59 points, were the “Potato-sized nodules”, a mixed team of journalists from New Scientist, the Times and Business Green.
Sharing second place, after leading at the half-way point, were “You cannot BSEERious” from the Bartlett School of Environment, Energy and Resources at UCL.
In fourth place, with 57 points, were “Risky Quizness”, from Verisk Maplecroft.
A certificate was awarded to the BBC for the best team name, as voted for by Carbon Brief staff: “High hopes [low confidence]”.
See the full leaderboard:
All the questions and answers from this year’s quiz can be found in this PDF document.
This year’s trickiest round was picture round two, which asked teams to match the quote to the author, with an average score of 5.9 out of 20 available points.
No team correctly guessed that “Chris Funk: Drought, Flood, Fire” was the source of the quote: “How greenhouse gases warm the atmosphere is pretty straightforward. It is really important that we understand this. But almost nobody does, because it is not something that we are taught in school.”
Science was the second hardest round, earning an average score of 6.1 points out of 20.
No team correctly guessed “religious leaders” as the least trustworthy source of climate information, according to a 2025 study using public polling from seven global south countries.
The highest-scoring round was general knowledge, with an average of 13.8 out of 20 questions answered correctly.
Carbon Brief would like to thank all the teams who took part and we look forward to hosting the quiz again in the spring of 2027.
If you would like to participate in next year’s quiz, please contact us in advance at quiz AT carbonbrief DOT org.
