An essential guide to the week’s key developments relating to climate change.

This week

Trump’s latest climate rollback

RULES REPEALED: The US Environmental Protection Agency (EPA) has begun dismantling Biden-era regulations limiting pollution from power plants, including carbon dioxide emissions, reported the Financial Times. Announcing the repeal, climate-sceptic EPA administrator Lee Zeldin labelled efforts to fight climate change a “cult”, according to the New York Times. Politico said that these actions are the “most important EPA regulatory actions of Donald Trump’s second term to date”.

WEBSITE SHUTDOWN: The Guardian reported that the National Oceanic and Atmospheric Administration (NOAA)’s Climate.gov website “will imminently no longer publish new content” after all production staff were fired. Former employees of the agency interviewed by the Guardian believe the cuts were “specifically aimed at restricting public-facing climate information”.

EVS TARGETED: The Los Angeles Times reported that Trump signed legislation on Thursday “seeking to rescind California’s ambitious auto emission standards, including a landmark rule that eventually would have barred sales of new gas-only cars in California by 2035”.

UK goes nuclear

NEW NUCLEAR: In her first spending review, UK chancellor Rachel Reeves announced £14.2bn for the Sizewell C new nuclear power plant in Suffolk, England – the first new state-backed nuclear power station for decades and the first ever under a Labour government, BBC News reported. The government also announced funding for three small nuclear reactors to be built by Rolls-Royce, said the Times. Carbon Brief has just published a chart showing the “rise, fall and rise” of UK nuclear.

MILIBAND REWARDED: The Times described energy secretary Ed Miliband as one of the “biggest winners” from the review. In spite of relentless negative reporting around him from right-leaning publications, his Department of Energy Security and Net Zero (DESNZ) received the largest relative increase in capital spending. Carbon Brief’s summary has more on all the key climate and energy takeaways from the spending review.

Around the world

  • UN OCEAN SUMMIT: In France, a “surge in support” brought the number of countries ratifying the High Seas Treaty to just 10 short of the 60 needed for the agreement to become international law, according to Sky News.
  • CALLING TRUMP: Brazil’s president Luiz Inácio Lula da Silva said he would “call” Trump to “persuade him” to attend COP30, according to Agence France-Presse. Meanwhile, the Associated Press reported that the country’s environmental agency has fast tracked oil and highway projects that threaten the Amazon.
  • GERMAN FOSSIL SURGE: Due to “low” wind levels, electricity generation from renewables in Germany fell by 17% in the first quarter of this year, while generation from fossil-fuel sources increased significantly, according to the Frankfurter Allgemeine Zeitung.
  • BATTERY BOOST: The power ministry in India announced 54bn rupees ($631m) in funding to build 30 gigawatt-hours of new battery energy storage systems to “ensure round-the-clock renewable energy capacities”, reported Money Control.

-19.3C

The temperature that one-in-10 London winters could reach in a scenario where a key Atlantic ocean current system “collapses” and global warming continues under “intermediate” emissions, according to new research covered by Carbon Brief.


Latest climate research

  • A study in Science Advances found that damage to coral reefs due to climate change will “outpace” reef expansion. It said “severe declines” will take place within 40-80 years, while “large-scale coral reef expansion requires centuries”.
  • Climatic Change published research which identified “displacement and violence, caregiving burdens, early marriages of girls, human trafficking and food insecurity” as the main “mental health” stressors exacerbated by climate change for women in lower and middle-income countries.
  • The weakening of a major ocean current system has partially offset the drying of the southern Amazon rainforest, research published in Environmental Research has found, demonstrating that climate tipping elements have the potential to moderate each other.

Captured

Aerosols have masked a substantial portion of historical warming. Chart for DeBriefed.

Aerosols – tiny light‑scattering particles produced mainly by burning fossil fuels – absorb or reflect incoming sunlight and influence the formation and brightness of clouds. In this way they have historically “acted as an invisible brake on global warming”. New Carbon Brief analysis by Dr Zeke Hausfather illustrated the extent to which a reduction in aerosol emissions in recent decades, while bringing widespread public health benefits through avoided deaths, has “unmasked” the warming caused by CO2 and other greenhouse gases. The chart above shows the estimated cooling effect of aerosols from the start of the industrial era until 2020.

Spotlight

How Carbon Brief turns complex research into visuals

This week, Carbon Brief’s interactive developer Tom Pearson explains how and why his team creates visuals from research papers.

Carbon Brief’s journalists will often write stories based on new scientific research or policy reports.

These documents will usually contain charts or graphics highlighting something interesting about the story. Sometimes, Carbon Brief’s visuals team will choose to recreate these graphics.

There are many reasons why we choose to spend time and effort doing this, but most often it can be boiled down to some combination of the following things.

Maintaining editorial and visual consistency

We want to, where possible, maintain editorial and visual consistency while matching our graphical and editorial style guides.

In doing this, we are trying to ease our audience’s reading experience. We hope that, by presenting a chart in a way that is consistent with Carbon Brief’s house style, readers will be able to concentrate on the story or the explanation we are trying to communicate and not the way that a chart might have been put together.

Highlighting relevant information

We want to highlight the part of a chart that is most relevant to the story.

Graphics in research papers, especially if they have been designed for a print context, often strive to illustrate many different points with a single figure.

We tend to use charts to answer a single question or provide evidence for a single point.

Paring charts back to their core “message”, removing extraneous elements and framing the chart with a clear editorial title helps with this, as the example below shows.

This before (above) and after (below) comparison shows how adding a title, removing extraneous detail and refining the colour palette can make a chart easier to parse.
This before (above) and after (below) comparison shows how adding a title, removing extraneous detail and refining the colour palette can make a chart easier to parse.

Ensuring audience understanding

We want to ensure our audience understands the “message” of the chart.

Graphics published in specialist publications, such as scientific journals, might have different expectations regarding a reader’s familiarity with the subject matter and the time they might be expected to spend reading an article.

If we can redraw a chart so that it meets the expectations of a more general audience, we will.

Supporting multiple contexts

We want our graphics to make sense in different contexts.

While we publish our graphics primarily in articles on our website, the nature of the internet means that we cannot guarantee that this is how people will encounter them.

Charts are often shared on social media or copy-pasted into presentations. We want to support these practices by including as much context relevant to understanding within the chart image as possible.

Below illustrates how adding a title and key information can make a chart easier to understand without supporting information.

This before (left) and after (right) comparison shows how including key information within the body of the graphic can help it to function outside the context of its original research paper.
This before (left) and after (right) comparison shows how including key information within the body of the graphic can help it to function outside the context of its original research paper.

When we do not recreate charts

When will we not redraw a chart? Most of the time! We are a small team and recreating data graphics requires time, effort, accessible data and often specialist software.

But, despite these constraints, when the conditions are right, the process of redrawing maps and charts allows us to communicate more clearly with our readers, transforming complex research into accessible visual stories.

South Africa’s offshore oil push meets grassroots resistance in court

Published

on

Layers of red dust coat South Africa’s Saldanha Bay, a legacy of the one billion-plus tonnes of iron ore exported from what was once a quiet coastal fishing town in the 1970s. Now the government wants to turn this area into the “oil and gas hub of South Africa”, but opposition from local communities and civil society could force a change of plan.

Since 2014 South Africa has developed a strategy for taking “full advantage” of its marine resources, known as Operation Phakisa. It has resulted in the mapping of more than 95% of the country’s nearly 3,000-kilometre coastline for offshore oil and gas exploration.

The plan seeks to “drill 30 exploration wells in 10 years”, which it estimates could lead to the production of an average of 370,000 barrels of oil and gas per day over 20 years, with Saldanha Bay earmarked as a key logistics hub. It also aims to develop other marine sectors like aquaculture, maritime transport and ocean tourism.

However, two major court cases against the government and oil giants Shell and TotalEnergies have challenged those plans, as coastal residents, allied with national civil society groups, have pushed back against oil concessions held by the multinationals, arguing they were not consulted, and that towns like Saldanha Bay could face social and environmental harms from the fossil fuel extraction.

    Melissa Groenink-Groves, programme manager at legal nonprofit Natural Justice, said the cases in South Africa could set a precedent for the whole region. “When communities win in the courts, the successes serve as inspiration for other communities to advocate [for] their rights in their own contexts,” she explained.

    She added that the legal challenges to Operation Phakisa also develop climate litigation in the African context, and could impact how environmental impact assessments are conducted going forward.

    Globally, as the oil and gas industry sets its sights on the ocean, with over 85% of new discoveries in 2024 made offshore, scientists and activists warn it could threaten marine life and coastal communities, and weaken the ocean’s ability to trap excess heat from the atmosphere, fuelling planetary warming further.

    Taking oil companies to court

    About 300 kilometres north of Saldanha Bay, the Aukotowa Fisheries Cooperative, backed by nonprofits The Green Connection and Natural Justice, has taken TotalEnergies to court over its plans to drill for oil and gas in a 30,000-square-kilometre block off South Africa’s west coast.

    The oil exploration block is in a biodiverse marine area bordering Namibia and South Africa known as the Orange Basin, which is a “highly relevant” sanctuary for endangered species, according to Nelson Mandela University’s Institute for Coastal and Marine Research.

    Among other grievances, the cooperative maintains that the company’s environmental impact assessment was flawed, failing to consider the project’s contribution to climate change, and that the government “placed the profits of a multinational corporation above the livelihoods of vulnerable coastal communities”. The Western Cape High Court concluded hearings in late March and is expected to deliver a ruling later this year.

    Walter Steenkamp, chairperson of the Aukotowa Cooperative, is concerned that the oil and gas drilling will lead to increased inequality, asking “for whom is the development? Definitely not for us.”

    In a written statement, TotalEnergies told Climate Home News that it “is a responsible operator fully committed to complying with all applicable South African legislation”.

    Communities and climate impacts at stake

    On the other side of the country, along South Africa’s eastern coastline, community-based nonprofit Sustaining the Wild Coast and partner organisations challenged Shell and Impact Africa’s exploration permit, arguing that the firms had failed to consult impacted communities – a legal requirement under South African law.

    Co-plaintiff Sinegugu Zukulu also said in 2022 that “oil and gas will lead to more emissions, and in the face of climate change, this is wholly irresponsible”.

    Following two rulings against the companies by lower courts, the case is now before South Africa’s highest Constitutional Court, which has reserved judgment since September 2025. A ruling against the companies would be final, effectively ending the exploration permit.

    Legal expert Groenink-Groves said oil exploration applications under Operation Phakisa have been “granted largely without properly assessing the devastating impact an oil spill could have on small-scale fishers, the risks of drilling in ultra-deep waters, [and] without accounting for climate change impacts associated with oil and gas exploitation”.

    She added that exploration applications have often failed to consider coastal management laws and in some cases, cross-border and regional environmental risks.

    Shell and South Africa’s Department of Mineral and Petroleum Resources did not respond to written requests for comment.

    South Africa’s offshore oil ambitions

    Fishers around South Africa, many of whom have for generations relied on marine resources for survival, say the country’s offshore oil and gas push is sacrificing their livelihoods for profit.

    “Why do they want to destroy our heritage? We can’t afford to say yes to oil and gas because the ocean is our source of life,” said Carmelita Mostert, a member of advocacy group Coastal Links and third-generation Saldanha Bay fisher.

    Yet with unemployment above 30%, alongside high levels of poverty and wealth inequality, the government sees Operation Phakisa as a vehicle for socioeconomic development.

    South Africa’s Minister of Mineral and Petroleum Resources Gwede Mantashe has described the court cases as “anti-development”, and claimed that the environmental organisations are funded by the CIA.

    Sifiso Dladla, a campaigner with human rights organisation groundWork, argued that the close relationship between the government and the fossil fuel industry – including its 3% contribution to gross tax revenue – limits the potential success of movements pushing for an inclusive energy system. Politicians “need money to win elections. Mining companies need the government to protect them,” he said.

    Patrick Bond, a political economist and sociology professor at the University of Johannesburg, said Operation Phakisa only makes economic sense if its social and environmental harms are ignored, adding that “if a genuine social cost of carbon analysis were done in any African fossil fuel project, there would be few – if any – able to justify the projects economically”. 

    At a global scale, Bond said oil multinationals have the financial backing of European governments – including France’s $2.8 billion stake in TotalEnergies – which can help make local resistance more effective where it has international allies to amplify the messages.

    For Saldanha Bay fisher Mostert, the fight is about protecting the livelihoods of coastal communities. “It is my hope that we can stand strong and protest,” she said. “If oil and gas is not allowed, our lives will be much easier and better – but if oil and gas goes ahead we will be in absolute agony.”

    Millions of kilograms of marine life taken from Australia’s marine protected areas every year, FOI finds

    Published

    on

    SYDNEY, Tuesday 11 August 2026 — New data obtained by Greenpeace Australia Pacific has found millions of kilograms of marine life are being taken from Australian marine parks by commercial fishers annually, as the government begins its review of the country’s Marine Parks Network.

    The data, released to Greenpeace in response to a Freedom of Information request, relates to 18 of Australia’s 60 Commonwealth marine parks, and shows almost 2.2 million kg of marine life is being fished each year, raising concerns about the true catch numbers across all marine protected areas.

    Greenpeace is calling for the Labor government to use the once-in-a-decade Marine Parks Network review, announced last fortnight, to ban industrial activities, including bottom trawling, longlining and oil and gas mining, from Australia’s Marine Parks Network, and increase fully-protected ocean sanctuaries within the network.

    Elle Lawless, Senior Campaigner at Greenpeace Australia Pacific, said:

    “It’s chilling to think of the true scale of destruction happening inside all of Australia’s marine parks, and how much of our precious ocean wildlife, like dolphins, turtles or seabirds, could be pulled out of protected areas as bycatch.

    “We’re talking about 6,600 kilograms of wildlife in one day, and that does not include what’s caught in the other 42 marine parks, many of which allow destructive fishing like longlining.

    “Australia has made significant progress in securing 52% of its oceans in marine parks; however, this intent is undermined by zones that allow damaging industrial fishing activities, such as bottom trawling and longlining. The review of Australia’s Marine Parks Network is a critical opportunity to fix what isn’t working and finally give our oceans the real protection they deserve.

    You wouldn’t expect someone to bulldoze a national park on land, so why should they be allowed to trawl in a marine park?”

    “Greenpeace Australia Pacific welcomes the Albanese Government’s review of the Commonwealth Marine Parks Network as a rare opportunity to strengthen our marine parks and ban industrial fishing in Australia’s marine protected areas.”

    The documents reveal that the south-west network has the largest catch volume, at 887,160kg per year, followed by the Coral Sea network, which extends out from the Great Barrier Reef, losing significant wildlife at 808,840kg annually.

    —ENDS—

    Notes:

    • More than half of Australia’s Marine Parks Network allow extractive industries, including industrial fishing and oil and gas mining.
    • The data, supplied by the Department of Agriculture, Fisheries and Forestry, does not specify how much of the catch is fish or bycatch, like non-target fish, turtles or seabirds, and is available on request.

    Marine Parks Explained

    Published

    on

    Australia’s network of marine parks is the largest in the world, covering more than half (52%) of Australia’s Commonwealth waters. You could be forgiven for assuming that a marine park is much like a national park on land: a highly protected place where people can enjoy nature while conservation efforts help habitats recover and wildlife thrive. You wouldn’t expect someone to bulldoze a national park, so why should they be allowed to bottom trawl in a marine park?

    The reality is that not all marine parks are equally protected. Australia’s Marine Parks Network is divided into different zoning categories, with each zone determining which activities are permitted and the level of protection provided.

    More than half of the Commonwealth Marine Parks Network allows industrial activities like oil and gas mining, and industrial fishing.

    Our survival, and the survival of our planet, depends on the ocean. The ocean produces more oxygen than all of our forests combined, sustains communities and regulates the earth’s temperature. It’s home to wondrous wildlife and important ecosystems like coral reefs and kelp forests.

    We love our big blue backyard

    Australia’s ocean is teeming with life that is found nowhere else on earth. Schools of colourful fish, vibrant coral reefs, endemic shark nurseries, pods of dolphins, families of whales, playful seal pups and threatened Jurassic-era turtles call Australian waters home.

    Since time began, from the turquoise waves to the deep blue, the ocean has connected our shorelines and communities, fed us, guided us and grounded us. We are intrinsically connected to our big blue backyard – more than 85% of us live within 50km of the shoreline. For tens of thousands of years, people have lived in harmony with the ocean and the wildlife within it, caring for and being sustained by its rich waters. Australia’s waters are some of the most unique and abundant places on Earth but our Marine Parks Network is falling short to properly protect them. 

    Australia’s marine parks aren’t living up to their name

    The Australian Commonwealth Marine Parks Network covers commonwealth waters 5.5km from the coast. The network is divided into 7 regional management areas, overall the network contains 60 marine parks. Zoning types determine what activities are allowed in each area. Over half of the network allows industrial activities, risking our most precious and threatened ocean wildlife.

    Within many of our marine parks, destructive industries are allowed to fish, trawl, dig and mine using barbaric and cruel methods. Here are some of the zones explained:

    • Bottom Trawling: Special Purpose (trawl) zones allow bottom trawling. This covers 10 marine parks totalling almost 13 million hectares. Bottom trawlers bulldoze the seafloor with weighted nets, deforesting our underwater forests; a cruel, indiscriminate and inefficient way to fish.
    • Other Industrial Fishing: Includes “Habitat Protection Zones, ““Multi Use Zones” and “Special Purpose Zones.” Fishing methods vary from park to park but many marine parks in these zones allow industrial fishing like longlining. Longlining involves setting lines that can be 100km long, bristling with deadly hooks designed to catch a specific fish species. But longlining is not a selective method of fishing – significant numbers of sharks, rays, turtles, dolphins and seabirds can be harmed or killed as bycatch in the process.
    • Oil and Gas Mining: Many “Special Purpose” and “Multi Use” zones allow seismic blasting and oil and gas mining. 30 marine parks or 65 million hectares of Australia’s highest conservation value areas for ocean wildlife are open for mining and exploration of oil and gas.
    • Ocean Sanctuaries: National Park and Sanctuary zones are fully and highly protected marine parks designed to conserve wildlife and their habitat, where fishing, mining, and other industrial activities are not allowed.

    Industrial fishing is one of the biggest threats to the ocean

    Marine parks on the east coast that allow bottom trawling. 10 marine parks across the whole network allow bottom trawling totalling almost 13 million hectares of ocean habitat for precious wildlife.

    In May, Greenpeace Australia Pacific sailed our campaigning vessel Oceania through some of Australia’s most beautiful and threatened marine parks. Our crew visited Jervis and Hunter marine parks to document their beauty, showcase what’s at risk and aim to expose the industrial fishing activities in these protected waters. Both of these marine parks allow bottom trawling and longlining methods of industrial fishing.

    Industrial fishing is ripping the ocean apart across the planet. Longlining, also known as longline fishing, is an industrial fishing method that involves the use of a fishing line with thousands of baited hooks. These fishing lines can stretch over 100 kilometers in length and are set to capture a fish species, often tuna or billfish species. But it is not a selective method of fishing  and often results in significant bycatch. This includes a range of non-target species like sharks, rays, sea turtles, marine mammals, and seabirds which are often injured or killed as bycatch.

    Bottom trawling involves dragging heavy weighted nets along the ocean floor. This fishing method is popular with commercial fishing companies, because it makes it easy to catch large quantities of fish in one go. But it also damages the seafloor, releasing carbon and can kill or injure non-target ocean life like coral, fur seals, dolphins and seabirds. You may have watched the reality of bottom trawling (and the benefits of ocean sanctuaries) in Ocean with David Attenborough, if not, add it to your watch list!  

    Fully protected ocean sanctuaries that ban industrial fishing and mining can protect ocean wildlife and underwater wonderlands for generations to come. Vast, robust sanctuaries create blue havens where ocean wildlife are safe from nets and hooks, and can truly rest, recover, thrive and replenish out into the surrounding waters. Ocean sanctuaries ensure a healthy ocean full of life.

    A once-in-a-decade chance to fix what’s falling short

    We have a unique opportunity to turn the tide.

    The Australian Government is asking for your feedback on how our Commonwealth Marine Parks Network is managed. This is our once-in-a-decade chance to protect ocean wildlife, ban industrial fishing and create more ocean sanctuaries.

    As part of the review the Government is asking for submissions from the public to hear from you on what improvements are needed to better protect our vast network of marine parks. Writing a submission is a powerful way to influence government decisions and create real change.

    This is the moment to ban industrial activities like bottom trawling and oil and gas mining. But only if they hear from YOU. Add your name!

    Greenpeace is calling on the Australian government to:

    1. Ban industrial activities from Australia’s Marine Parks Network: Ban industrial activities, such as industrial fishing, seismic blasting and oil and gas mining, from Australia’s marine parks.

    2. Create more ocean sanctuaries: Increase fully protected sanctuaries in Australia’s marine parks based on science principles.

    3. Connect Australia’s Marine Parks Network to the High Seas: mCreate seascape connectivity by linking Australian marine parks to new high seas ocean sanctuaries.

    Substantiation that more than half of the Marine Parks Network permits industrial activity comes from a peer-reviewed systematic literature review (Phillips et al. 2025, PLOS One, https://doi.org/10.1371/journal.pone.0307324). The study found that within the Commonwealth Marine Parks Network specifically, “all zones are considered partially protected areas, meaning areas where extractive activities are permitted, except ‘Pink zones’ (Preservation Zones; IUCN Ia) and ‘Green Zones’ (IUCN II).” In other words, every Commonwealth marine park zone type other than the network’s strict no-take sanctuary and national park zones (IUCN Ia and II) permits some form of extractive industrial activity. Since no-take zones are the minority zone type across the network by area, this supports the conclusion that the majority of the network’s area is zoned to permit industrial activity.

    DCCEEW Australian Marine Parks spatial dataset (https://fed.dcceew.gov.au/datasets/erin::australian-marine-parks/explore), filtered by zone type. This confirms that 38.43% of the network’s area is zoned as Sanctuary or National Park zones (IUCN Ia and II). These are the no-take categories excluded from the peer-reviewed study’s definition of partially protected/industrial-permitting zones. The remaining 61.57% of the network falls within the zone categories the study classifies as permitting industrial activity (per The MPA Guide definition of “industrial” applied in Phillips et al. 2025), directly corroborating the peer-reviewed finding with current Commonwealth-specific spatial data.

    For further information on activities permitted within the Marine Parks Network Zoning, you can refer to the Management Plans zoning and rules for each Marine Parks Network area, for example: Temperate East, Coral Sea, North.
