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

This week

Preparing for 3C

NEW ALERT: The EU’s climate advisory board urged countries to prepare for 3C of global warming, reported the Guardian. The outlet quoted Maarten van Aalst, a member of the advisory board, saying that adapting to this future is a “daunting task, but, at the same time, quite a doable task”. The board recommended the creation of “climate risk assessments and investments in protective measures”.

‘INSUFFICIENT’ ACTION: EFE Verde added that the advisory board said that the EU’s adaptation efforts were so far “insufficient, fragmented and reactive” and “belated”. Climate impacts are expected to weaken the bloc’s productivity, put pressure on public budgets and increase security risks, it added.

UNDERWATER: Meanwhile, France faced “unprecedented” flooding this week, reported Le Monde. The flooding has inundated houses, streets and fields and forced the evacuation of around 2,000 people, according to the outlet. The Guardian quoted Monique Barbut, minister for the ecological transition, saying: “People who follow climate issues have been warning us for a long time that events like this will happen more often…In fact, tomorrow has arrived.”

IEA ‘erases’ climate

MISSING PRIORITY: The US has “succeeded” in removing climate change from the main priorities of the International Energy Agency (IEA) during a “tense ministerial meeting” in Paris, reported Politico. It noted that climate change is not listed among the agency’s priorities in the “chair’s summary” released at the end of the two-day summit.

US INTERVENTION: Bloomberg said the meeting marked the first time in nine years the IEA failed to release a communique setting out a unified position on issues – opting instead for the chair’s summary. This came after US energy secretary Chris Wright gave the organisation a one-year deadline to “scrap its support of goals to reduce energy emissions to net-zero” – or risk losing the US as a member, according to Reuters.

Around the world

  • ISLAND OBJECTION: The US is pressuring Vanuatu to withdraw a draft resolution supporting an International Court of Justice ruling on climate change, according to Al Jazeera.
  • GREENLAND HEAT: The Associated Press reported that Greenland’s capital Nuuk had its hottest January since records began 109 years ago.
  • CHINA PRIORITIES: China’s Energy Administration set out its five energy priorities for 2026-2030, including developing a renewable energy plan, said International Energy Net.
  • AMAZON REPRIEVE: Deforestation in the Brazilian Amazon has continued to fall into early 2026, extending a downward trend, according to the latest satellite data covered by Mongabay.
  • GEZANI DESTRUCTION: Reuters reported the aftermath of the Gezani cyclone, which ripped through Madagascar last week, leaving 59 dead and more than 16,000 displaced people.

US emissions, MtCO2e, under a “current policy” scenario in which the EPA removes key federal climate regulations

Repealing the US’s landmark “endangerment finding”, along with actions that rely on that finding, will slow the pace of US emissions cuts, according to Rhodium Group visualised by Carbon Brief. US president Donald Trump last week formally repealed the scientific finding that underpins federal regulations on greenhouse gas emissions, although the move is likely to face legal challenges. Data from the Rhodium Group, an independent research firm, shows that US emissions will drop more slowly without climate regulations. However, even with climate regulations, emissions are expected to drop much slower under Trump than under the previous Joe Biden administration, according to the analysis.

How a ‘tree invasion’ helped to fuel South America’s fires

This week, Carbon Brief explores how the “invasion” of non-native tree species helped to fan the flames of forest fires in Argentina and Chile earlier this year.

Since early January, Chile and Argentina have faced large-scale and deadly wildfires, including in Patagonia, which spans both countries.

These fires have been described as “some of the most significant and damaging in the region”, according to a World Weather Attribution (WWA) analysis covered by Carbon Brief.

In both countries, the fires destroyed vast areas of native forests and grasslands, displacing thousands of people. In Chile, the fires resulted in 23 deaths.

Multiple drivers contributed to the spread of the fires, including extended periods of high temperatures, low rainfall and abundant dry vegetation.

The WWA analysis concluded that human-caused climate change made these weather conditions at least three times more likely.

According to the researchers, another contributing factor was the invasion of non-native trees in the regions where the fires occurred.

The risk of non-native forests

In Argentina, the wildfires began on 6 January and persisted until the first week of February. They hit the city of Puerto Patriada and the Los Alerces and Lago Puelo national parks, in the Chubut province, as well as nearby regions.

In these areas, more than 45,000 hectares of native forests – such as Patagonian alerce tree, myrtle, coigüe and ñire – along with scrubland and grasslands, were consumed by the flames, according to the WWA study.

In Chile, forest fires occurred from 17 to 19 January in the Biobío, Ñuble and Araucanía regions.

The fires destroyed more than 40,000 hectares of forest and more than 20,000 hectares of non-native forest plantations, including eucalyptus and Monterey pine.

Dr Javier Grosfeld, a researcher at Argentina’s National Scientific and Technical Research Council (CONICET) in northern Patagonia, told Carbon Brief that these species, introduced to Patagonia for production purposes in the late 20th century, grow quickly and are highly flammable.

Because of this, their presence played a role in helping the fires to spread more quickly and grow larger.

However, that is no reason to “demonise” them, he stressed.

Forest management

For Grosfeld, the problem in northern Patagonia, Argentina, is a significant deficit in the management of forests and forest plantations.

This management should include pruning branches from their base and controlling the spread of non-native species, he added.

A similar situation is happening in Chile, where management of pine and eucalyptus plantations is not regulated. This means there are no “firebreaks” – gaps in vegetation – in place to prevent fire spread, Dr Gabriela Azócar, a researcher at the University of Chile’s Centre for Climate and Resilience Research (CR2), told Carbon Brief.

She noted that, although Mapuche Indigenous communities in central-south Chile are knowledgeable about native species and manage their forests, their insight and participation are not recognised in the country’s fire management and prevention policies.

Grosfeld stated:

“We are seeing the transformation of the Patagonian landscape from forest to scrubland in recent years. There is a lack of preventive forestry measures, as well as prevention and evacuation plans.”

Bonn Bulletin: Tackling climate crisis is “hardest” challenge ever, Stiell says

Published

on

Kicking off proceedings at the mid-year climate talks in Bonn amid fraught global geopolitics, UN climate chief Simon Stiell told delegates that tackling the global climate crisis is “the hardest, but most important, thing humanity has ever tried to do together”.

Perhaps hoping to forestall the usual diplomatic wrangling that routinely bogs down the talks, he warned governments that there is no time to “re-open past debates or renegotiate commitments already made”.

Instead, he added, there is an imperative to accelerate real-world action as deadly heat intensifies and the fossil-fuel cost crisis sparked by the Iran war strangles economies, “taking a wrecking ball to lives and prosperity”. 

That message seemed to sink in with the negotiators in Bonn, where the opening session kicked off only an hour late and was not marred by agenda rows, which delayed the start of the talks by a day last year.

On bridging the gap between the negotiations and the real economy, Stiell called for elevating the Global Climate Action Agenda, a goal long promised but never fully delivered.

But, he added, Türkiye – working with Australia – is now building on the efforts by last year’s COP30 presidency to streamline this process into six thematic areas, including boosting energy and food security, curbing methane and strengthening the resilience of cities.

What to expect from the Bonn climate talks

Stiell was also keen to stress that the formal negotiations remain central to driving implementation of the Paris Agreement. He urged governments in Bonn to advance key issues including the Global Goal on Adaptation, the delivery of the outcomes of the first Global Stocktake and the development of a new just transition mechanism.

The first Global Stocktake was an assessment of countries’ collective progress in meeting the goals of the Paris Agreement, which led to a 2023 agreement to transition away from fossil fuels in energy systems and a 2030 goal to triple renewable energy, among other things.

Hinting at upcoming reforms to the UN climate regime – which has often been accused of failing to keep pace with advancements in the real world – Stiell said all institutions must continuously evolve and improve. The UN climate secretariat has heard countries’ calls to work more efficiently, support access to climate finance and reduce the reporting burden on governments, he added.

Türkiye to outline targets for Action Agenda

While Australia will run the negotiations at COP31, for co-host Türkiye – which is organising the talks in Antalya – the focus is on the so-called Global Climate Action Agenda. This is a sprawling smorgasbord of around 500 voluntary initiatives bringing together governments, businesses, investors, cities and civil society. It covers everything from strengthening power grids for clean energy, to restoring degraded forests and land, and reducing emissions from buildings.

COP31 President-Designate Murat Kurum told the opening session of the Bonn talks his team will present the “main framework” of the Action Agenda on Tuesday, adding it will be “based on concrete and tangible targets”. He also said Türkiye will announce a roadmap for translating what happens in the negotiations into the real world, which will ”point to a science-based process with highly clear and defined outcomes” and steps for getting there.

“In the second decade of the Paris Agreement, the COP31 Action Agenda will bring the outcomes of the first Global Stocktake to life, and we will make a strong start to the second decade,” Kurum said. 

In a joint letter issued in May, the two host nations said COP31 will be shaped as an “Implementation COP” and a “COP of the Future,” aimed at translating commitments into tangible and trackable progress. They outlined priority areas – to be achieved through the six axes of the Action Agenda defined ahead of COP30 – including electrification, zero waste, resilient cities, sustainable agriculture, green industrial transformation and climate finance.

Electrification emerges as COP31 priority

Chiming with this, Australia’s Chris Bowen, the COP31 president of negotiations, made the global energy transition the centerpiece of his opening intervention in Bonn.

This year’s climate summit, he said, must send investors and corporations the message that countries are “collectively committed” to building up renewable energy and reducing fossil fuel reliance. Fossil fuels were not directly mentioned in the main outcome at COP30 last year after countries failed to agree on developing a global transition roadmap, which Brazil is now putting together outside of formal negotiations.

Bowen, Australia’s minister of climate change and energy, said that, while energy crises like the one the world is going through now will become more frequent and more unpredictable, accelerating the shift to cleaner sources will “ease shocks to our energy systems”.

He identified progress on electrification as a priority for COP31, pointing to an assessment by the International Energy Agency (IEA) that electricity’s share of final energy consumption needs to reach 35% by 2035 to keep the 1.5C temperature goal in sight.

“In a world of geopolitical uncertainty and energy disruption, the transition is not a risk,” Bowen added, “it is the solution and an immense opportunity”.

Tensions around trade and climate surface again 

Over the weekend, it became clear that discussions on trade and climate would once again become a source of contention between countries – if not as explosively as they did at the start of the talks a year ago.

As agreed in the COP30 Global Mutirão decision, a series of dialogues on trade and climate will be held in Bonn yearly from 2026 to 2028. Climate Home News understands that the G77 + China has expressed discontent about the organisation of the first dialogue that will take place on June 13, because it plans to incorporate contributions from a range of organisations rather than just governments.

In a statement at the opening plenary, Uruguay, on behalf of the G77 group of developing nations, “encouraged Parties [countries] to engage constructively in the dialogue in a robust and structured manner”. Many in the Global South are concerned that international trade measures to make products greener, such as the European Union’s carbon levy on imports, could end up discriminating against them.

Russia warned during its opening statement that the new dialogue should not be used to create trade barriers.

Comment: Indonesia’s failing Just Energy Transition Partnership is a cautionary tale

Avantika Goswami, climate change and green economy programme manager at the India-based Centre for Science and Environment, told Climate Home News that the UN climate secretariat has been unclear and untransparent about what will be discussed at the dialogue. “We don’t know if observers and civil society are going to be able to contribute,” she added.

After the three mid-year dialogues, in 2028 there will be a high-level event for countries to exchange their views and experiences, and the officials in charge will have to present a report summarising these discussions.

At Monday’s opening session, Antwi-Boasiako Amoah, the Ghanian chair of the African Group of Negotiators, said it would be “important to provide clarity on how they intend to present the report” and suggested that the co-chairs of the Bonn talks should consult with countries on how best to do that.

Bowen urged to lead with vision and ambition to accelerate fossil fuel phase out at Bonn climate meeting, as global energy crisis bites

Published

on

Bonn, Germany, Monday 8 June 2026 — As the UN climate negotiations in Bonn commence, Greenpeace Australia Pacific is calling on Climate and Energy Minister Chris Bowen to lead with vision and ambition to advance multilateral climate cooperation, and use his unique position to drive concrete progress at COP31 and ensure a meaningful partnership with the Pacific.

In the context of a global energy crisis and turbulent geopolitics, the Bonn Climate Change Conference will be a critical moment to sustain emerging political momentum towards a just transition away from fossil fuels. The midway point on the road to COP31 in Türkiye in November, Bonn will be the first time Minister Bowen has attended a major UN conference in his role as COP31 President of Negotiations.

The start of the Bonn meetings also marks 100 days since the illegal US-Israel war on Iran sparked a global energy shock and after 57 countries including Australia met in Santa Marta, Colombia in April for the world’s first conference on the transition away from fossil fuels — a landmark moment signalling political winds of change in the face of threats to multilateralism.

Speaking from Bonn, Dr Simon Bradshaw, COP31 Lead at Greenpeace Australia Pacific, said: “Amidst a global energy crisis, accelerating climate disasters and a looming super El Niño, the urgency to accelerate climate action and break free from fossil fuel dependence has never been clearer.

“Minister Bowen has been telling Australia and the world that we are in a global ‘fossil fuel crisis’, and that unhooking from fossil fuels is fundamental both to tackling the climate crisis and to ensuring secure and affordable energy. It’s time to match that message with a clear vision and agenda for COP31 — one that has the transition away from fossil fuels at its heart.

“As COP31 President of Negotiations, Australia has both the opportunity and responsibility to build on the momentum of COP30 in Belém and the recent landmark conference in Santa Marta on transitioning away from fossil fuels. This includes leading by example at home, with an immediate halt to new fossil fuel projects — including the mammoth proposed Browse gas project — and committing to develop a national roadmap away from fossil fuel production.”

“Few countries have as much skin the game as Australia: we are a country highly vulnerable to extreme heat, fires, floods and other impacts of climate change, we are suffering the consequences of fossil fuel dependency in terms of our energy security and affordability, but we have some of the world’s best renewable energy opportunities.

“Bonn is a key moment for the incoming Presidency to start shaping the vision, building the necessary trust, and actively setting priorities and expectations for the COP. We therefore hope and expect our Minister to be much more vocal and active in Bonn.

“Australia, in partnership with the Pacific, is taking the reins of global climate cooperation at a critical moment in the world’s transition away from fossil fuels. There is no more time to lose.”

Also in Bonn, Shiva Gounden, Head of Pacific at Greenpeace Australia Pacific, said: “Multilateral cooperation is the antidote to climate and geopolitical chaos. At Bonn, Pacific nations’ legacy of leadership from the frontlines of the climate crisis can be our guiding star as we build a more peaceful and secure world for all.

“We must build on the progress at Santa Marta and break the hold fossil fuels have on our global security and economies. Pacific nations are already facing the brunt of a global climate crisis, but now facing the compounding injustice of an energy crisis brought on by fossil fuel dependence. We did not create either of these crises, but are among the most exposed to both.

“The International Court of Justice made clear that responsibility to address the climate crisis extends beyond borders and that continuing to expand fossil fuel production, including for export, could constitute an internationally wrongful act — a ruling that has now been overwhelmingly endorsed by the UN General Assembly. Continuing down the fossil fuel path, and failing to align efforts with limiting warming to 1.5C, is a breach of our international legal obligations.

“We must not lose sight of what’s needed — by elevating the voices of Pacific leaders, backing Pacific-led solutions, and maximising the opportunity of the Pacific pre-COP, we can ensure the 1.5°C imperative and the transition away from fossil fuels are central to the agenda at COP31, and that communities are granted the finance they need to build a strong, resilient future beyond fossil fuels.”

Ahead of SB64, Greenpeace International has produced a policy briefing outlining the core elements of a just transition away from fossil fuels and the urgent, priority actions needed from national governments and through global co-operation to make it a reality.[1]
