Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Hurricane Melissa
‘TOTAL DEVASTATION’: Hurricane Melissa has killed at least 49 people after sweeping through the Caribbean islands of Jamaica, Cuba, Haiti and Bermuda, reported Independent. Jamaica’s prime minister Andrew Holness said the storm left “total devastation”, destroying homes and infrastructure and leaving people “stranded on roofs and without power”, said BBC News. In Haiti, at least 30 people were killed in floods, Reuters added.
WARM WATERS: Melissa is tied as the strongest Atlantic hurricane to ever hit land, slamming Jamaica with winds of 185mph and fuelled by anomalously warm waters, reported the Associated Press. Fossil-fuelled climate change made the storm “four times more likely”, according to analysis cited by Agence France-Presse. Early estimates suggest infrastructure damage alone could amount to 40% of Jamaica’s gross domestic product, said the newswire.
RECORD RAINS: Elsewhere, Al Jazeera reported on major floods in central Vietnam, where the former imperial city of Huế saw record rainfall of more than 1,000mm over a 24-hour period, according to the country’s weather agency. The Associated Press reported that climate change is “driving more intense winds, heavier rainfall and shifting precipitation patterns across East Asia”.
Climate plans off track for 1.5C
‘DRASTICALLY SHORT’: The latest national climate plans will cause global emissions to drop 10% by 2035 from 2019 levels, “bending the emissions curve downwards for the first time”, but falling “drastically short” of the 60% cut needed to keep 1.5C in sight, said the Guardian. The plans – known as nationally determined contributions (NDCs) under the Paris Agreement – were assessed by the UN in a synthesis report ahead of COP30, the publication said. The 10% cut reflects plans announced by China and the EU, in addition to formal submissions from 64 countries, according to Reuters.
OVERSHOOT ‘INEVITABLE’: UN secretary-general António Guterres said in a joint interview with the Guardian and the Amazonian publication Sumaúma that overshooting 1.5C of global warming was now “inevitable” and would have “devastating consequences”. Guterres “did not give up on the [1.5C] target”, but urged world leaders to “change course” during COP30 to ensure the “overshoot is as short as possible and as low in intensity as possible to avoid tipping points like the Amazon”.
Around the world
- DELIVERY: The UK government published its “carbon budget and growth delivery” plan, outlining policies to meet its mid-2030s climate targets. Read more in Carbon Brief’s in-depth coverage of the plan.
- DEAL UNEARTHED: Donald Trump and Xi Jinping have settled a dispute over rare-earth mineral supplies during trade talks, said the Guardian. Trump described the talks as “amazing” and agreed to reduce tariffs on Chinese goods by 10%, it added.
- AVOIDABLE DEATHS: Climate change and policy “failures” are leading to “millions” of avoidable deaths each year, according to Le Monde’s coverage of the latest Lancet Countdown report on health and climate change.
- DEFORESTATION DOWN: On the eve of hosting COP30, Brazil’s government announced an 11% drop in annual deforestation in the Brazilian Amazon, the fourth consecutive annual fall and lowest deforestation rate since 2014, reported Agence France-Presse.
- DUTCH ELECTION: Democrats 66 (D66), the centrist party led by former climate minister Rob Jetten, narrowly won a snap general election in the Netherlands, said Brussels Signal.
- EU FLEXIBILITY: As the EU continues to negotiate 2040 emissions targets, the bloc is considering a “more flexible path” for industries to meet the goals, reported Reuters.

Captured
Carbon Brief explored the importance of soil health for food security and climate change in a new Q&A. As the diagram above illustrates, agricultural soil is composed of four layers – known as soil horizons – containing varying quantities of minerals, organic matter, living organisms, air and water. The world’s soils have lost 133bn tonnes of carbon since the advent of agriculture around 12,000 years ago, with crop production and cattle grazing responsible in equal part.
Spotlight
Crackdowns on climate and environmental activism
This week, Carbon Brief speaks to Mary Lawlor, UN special rapporteur on human rights defenders, who led a recent report highlighting crackdowns on the rights of climate and environmental activists around the world.
Carbon Brief: Why do you see climate change as a human-rights issue?
Mary Lawlor: I don’t think there’s any doubt about climate change being a human-rights issue nowadays, because everyone can see it. It interferes with so many rights. The right to food, for example. We’ve seen the situation where drought, storms and floods interfere with food production. And then if you look at the right to life – according to the WHO, we’re currently seeing an average of 175,000 heat-related deaths per year around the world, and those numbers will increase. But we now also have advisory opinions of the ICJ, the Inter-American Court of Human Rights, the International Tribunal for the Law of the Sea, all of which state clearly that climate change is a reality. They see it as a human-rights crisis.
CB: What human-rights violations are being faced by climate and environmental activists around the world right now?
ML: We went to a lot of Indigenous communities in the Amazon and we saw firsthand the threats against Indigenous defenders in Brazil who are opposing carbon-credit projects in their territories, where they themselves have been reducing deforestation with success for years. Then, for example, there were smears against a lawyer in Argentina who was supporting communities in their legal fight against the extraction of lithium from their territories without their consent. And, then, you have surveillance of climate activists organising peaceful protests against new fossil-fuel projects, for example, in the Philippines. So it’s kind of like an octopus, the tentacles are reaching out.
In some of the more developed countries, like France and Spain, you have accusations of terrorism against peaceful climate-justice movements. In Germany, you had the investigation and prosecution of a climate-justice group for alleged organised crime based solely on their peaceful protests that put no human being in danger and did no harm to anyone.
CB: What are some examples that you’ve seen of good practice by governments in relation to the work of climate and environmental activists?
ML: My favourite is Brazil and MST [Landless Workers’ Movement]. They were aided in their tree-planting programme by the federal authorities, who provided helicopters and the federal highway police piloted these helicopters. Seeds of the endangered juçara palm and araucaria trees could be air-dropped over land in Paraná, after the devastating fires that took place. So that’s my absolute favourite, because it showed how a state and defenders can work together as allies to prevent destruction and even worse climate change.
CB: According to Global Witness, 413 land and environmental defenders were killed in Brazil during 2012-2024. What is the current situation for environmental defenders in Brazil going into COP30?
[Brazil] are really making efforts, as far as I can see, to address the root causes – and this is really why human-rights defenders are in such danger – that is, land is at the heart of all the problems there. But progress is still very slow. At the moment, only 16 territories have been demarcated by [Brazilian president] Lula and that is hugely important because, as I said, it’s at the root of pretty much all the attacks and killings by either the thugs associated with the companies, or the big landowners, the illegal logging, and all the stuff that is happening there. So that is something that we really need a speed up of – the demarcation of Indigenous lands.
When it comes to COP30, they’ve put some effort into making it more inclusive, especially when it comes to bringing the voices and experiences of Indigenous defenders into the negotiations. Now we’ll see what will happen in November and what the negotiations bring.

The invigorating thing about public speaking is that you never quite know who is in the audience. There’s always a chance, of course, that someone wants to have a bit of a go at you, or maybe there’s an attendee with a particular take on things, who wants to ask one of those ‘questions that is more of a statement’; and then there’s those precious moments when the stars align and a memorable connection is made.
A couple of weeks ago, I’d participated in a panel discussion at an event, and the crowd was beginning to dissipate when a couple of strangers approached me to introduce themselves and say ‘hello’.
It turned out that Helen, Miranda, and I had all been in the same room in April, when each of us was part of the Greenpeace contingent inside Woodside’s 2026 Annual General Meeting in Perth, though we did not meet that day.
AGMs are significant set-piece occasions for companies, at which their corporate leadership wants to project competence and boost investor confidence. But for those of us with other concerns on our minds, an AGM is an opportunity to hold corporate leaders to account.
This year, a significant number of community advocacy groups, including Greenpeace, were present at Woodside’s AGM to challenge the company on its plans to drill for gas around Scott Reef—Australia’s largest freestanding oceanic reef atoll, and host to an incredible array of rare and endangered creatures, including green sea turtles and pygmy blue whales.
My role was to accept a shareholder proxy, suit up, and ask the company’s chair, Richard Goyder, some direct questions about the environmental damage that Woodside’s plans threaten to Scott Reef and the global climate.
Helen and Miranda, though, were present to play a completely different role. ‘We were a bit nervous that day’, Miranda told me. And no wonder, given what they were planning to do.
As new CEO Liz Westcott took the lectern, she was abruptly interrupted by a literally unearthly sound: whale song, playing from a speaker that Greenpeace activists had snuck into the room.
It was an aural haunting of Woodside’s AGM by the ghosts of its business strategy. Westcott opted to try to continue speaking, while security moved among the rows, attempting without success to work out where the sound was coming from.
When the whale track had played through, the relief on the podium felt palpable; but the return to corporate calm was short-lived.
Miranda, Helen, and other small groups of choristers—all evidently talented singers in their own right—began to stand up in small groups to perform a bespoke ‘Save Scott Reef’ variation on an iconic Australian song:
Hands off Scott Reef
Don’t be so Reckless
She don’t like that kind of behaviour…
It is a cliche, but true, to say that bravery comes in many different forms. It demands guts and resolve to stand up in a closed and heavily securitised room, with an unsympathetic audience; and to sing a song of no denying to one of the most powerful corporations in Australia, unaccompanied, from a cold start, with only your voices to fill the cavernous corporate space.
It was a wonderful thing to witness: the moral clarity of the message and the bold cheekiness of the activity; and a profoundly galvanising thing to feel, the indefatigable lifting of the spirit that we experience when we hear human voices rising in harmony and purpose. Miranda, Helen and their mates were brilliant.
Don’t be so Reckless…
As each small group rose in choreographed turn to pick up the song, they were apprehended by security and escorted out, singing to the last, as they were exited from the room.
Already, more than 500,000 people have joined the campaign to stop Woodside from drilling gas at Scott Reef. So when Helen, Miranda and friends stood up to sing, they did so on behalf of more than half a million people.
‘I’d never done anything like that before’, Helen told me, ‘I’d definitely do it again’.
Protest songs are both catalytic and emblematic of dynamic moments of social change. There is beauty, creativity, defiance, camaraderie and love to be found in singing together.
Helen and Miranda, it was great to meet you both. To you and all the other amazing folks who stood up and sang, thank you for your courage, commitment and the power of your voices. Your singing mattered for the half million, for the whales and the other creatures of Scott Reef, and for life in the ocean and on earth itself.

Q and A
A few people have asked me recently about where the implementation of the national nature law reforms stand? Specifically, It seemed like good news when the Environment Protection and Biodiversity Conservation Act (EPBC) reforms were passed last year, but now it appears that they could be going wrong in the implementation. What’s happening?
We welcomed the Australian parliament’s passing of long-awaited nature law reforms just before Christmas last year as a fulfilment of an election promise, but remained clear-eyed that the proof of these reforms would be in how well they were implemented.
At this stage, the first two draft National Environmental Standards (NES) released by Federal Environment Minister Murray Watt’s department fall well short of what is required to actually protect nature. So things are once again in the balance.
The NES are the rules intended to guide decisions on projects that require assessment under the EPBC Act. They should draw a hard line to protect nature, but instead, the proposed standards are full of loopholes that legal experts warn are inimical to achieving the whole point of the Act–the protection of nature.
Glenn Walker who is Greenpeace Australia Pacific’s Head of Nature Program has mapped out the shortcomings of the NES in great detail on our blog. Greenpeace has made is views clear to both the Federal Environment Department and Minister Murray Watt, urging that the NES must be fixed, as have many others.
We are continuing to work closely with other environmental organisations, both to engage closely and to campaign publicly–there is still the opportunity to get this right to achieve the potential of the amended EPBC Act to actually do what it says on the cover–protect the environment.
