As 2024 turns to 2025, we asked subscribers to our newsletter what the top climate issues of the upcoming year will be. With climate destruction growing, their responses clearly indicate they want to see more ambition in tackling climate change and more honesty on how climate action is going.
Here’s our summary of responses from our always passionate, well-informed readers and our analysis of when, where and how we can judge whether the powers-that-be are stepping up to the challenge or falling short.
1. Governments must make bigger commitments to cut emissions – and stick to them
Under the 2015 Paris climate agreement, all governments have to submit a climate plan – known as a nationally determined contribution (NDC) to the United Nations every five years.
The third round of these plans is due next year, ten years on from Paris. Most will add a 2035 emissions reduction aim on to their existing 2030 target and their more long-term goals to reach net zero in 2050, 2060 or 2070.
Several Climate Home readers said NDCs would be a top climate issue for 2025. One said they should be “challenging but realistic” and another said they “must align with actionable policies”.
They will certainly have to be more ambitious than the last round five years ago if the world stands a chance of limiting global warming to 1.5C or even 2C above pre-industrial levels.
The United Nations said in October that, even if implemented in full, existing NDCs put the world on course for a catastrophic 2.6C of global warming.
2. Governments must prepare for worsening climate change impacts
While the final figures are not out yet, the World Meteorological Organisation has said that 2024 looks set to be the hottest year on record. But it may also be the coolest year we see for a while. Even if emissions peak, the world will keep getting hotter until we reach net zero globally.
Climate change worsened dozens of disasters in 2024 from extreme rain in Spain to a heatwave in West Africa and typhoons in the Phillipines. The World Weather Attribution group found that 26 disasters linked to climate change this year killed over 3,700 people and displaced millions.
We’re likely to see more disasters in 2025. One South American reader reported worries about drought, Amazon rainforest fires and rising temperatures while another said “extreme weather patterns demand immediate attention”.
In this context, adaptating to climate change is key. At COP30 in Belém in November, governments are due to agree on a list of indicators on how to measure whether they are adapting to climate change in areas like water, food and health. The big debate will be whether the provision of finance to developing countries will be one of those indicators.
For the destruction that can’t be adapted to, the new UN loss and damage fund is supposed to help. Its new executive director – Ibrahima Cheikh Diong – hopes to start handing out money to climate victims by the end of 2025 and hire most of its staff in 2026.

3. Nature conservation should pick up pace
Due partly to climate change, species are dying off at a sickening rate. Last year’s biodiversity conference, COP16 in the Colombian city of Cali, hoped to address that. While it had some successes – particularly in handing power to indigenous people – it ran out of time to agree on how to pay for nature protection.
With two years until COP17, governments have agreed to continue COP16 on February 25-27 in Rome. “Securing adequate and predictable financing will be central to our efforts,” said COP16 president Susana Muhamad.
Responses to the survey indicate our readers are concerned about nature, both on land and in the oceans where plastic pollution is a particular threat to nature. Talks to set up a UN treaty to tackle plastic failed in Busan in December 2024 but will continue at some point in 2025.
4. We need less misinformation, accounting tricks and jargon
With Donald Trump coming into power, our readers are worried about misinformation on climate change. Trump has promised to pull out of the Paris Agreement and his often inaccurate criticisms of climate action are likely to influence the public conversation in the US and abroad in 2025.
The United Nations is trying to counter misinformation on climate change with a $10-15 million fund for non-governmental organisations researching the issue and developing communication strategies and public awareness campaigns.

But its not just Trump’s claims that concern readers, they are also concerned that governments that do recognise climate change are overselling their climate action using accounting tricks.
A Canadian reader pointed out that the emissions from international aviation are not included in nations’ greenhouse gas inventories and neither are those from forest fires, as these are considered natural and therefore not the government’s responsibility. Climate Home has highlighted how countries like Guyana use forest carbon accounting techniques to claim to be carbon negative despite booming oil production.
Another reader criticised the “language barrier” caused by the jargon and technical acronyms that are common in climate policy. “Bridging the gap between technical acronyms and the lived experiences of skeptics or reluctant individuals is vital”, they said. Another said climate communicators should “avoid masking global warming’s mechanics with unclear terms” and “focus on transparency”.
Will the Intergovernmental Panel on Climate Change’s scientists heed this as they start writing up a special report on climate change and cities this year?
5. The roll-out of green technology must quicken
Decarbonising the world is going to require a huge variety of technology and the good news is that the roll-out of green solutions like solar panels and electric vehicles continues to pick up pace every year.
Our readers highlighted technology like heat-pumps, micro-grids and the recycling of aluminium. Other solutions proposed by our readers include city design which encourages walking and public transport, like Utrecht in the Netherlands, and tackling private plane use as “unnecessary luxury emissions”.
All these solutions have restrained the growth in emissions but have yet to stop them growing completely. Will 2025 be the year that changes and we reach peak emissions? It’s possible but by no means certain.

Race to host High Seas Treaty HQ heats up as Chile reaffirms bid
When José Antonio Kast took office as Chile’s new president in March, one of his first moves was to put the brakes on plans to expand two protected marine parks – raising doubts about the country’s high-profile bid to host the headquarters of the High Seas Treaty.
But during the UN General Assembly last month, the right-wing leader reaffirmed his leftist predecessor’s ambition for Chile to host the landmark global pact, which came into effect in January and provides a legal framework to protect the waters of the high seas beyond national jurisdiction that cover about two-thirds of the world’s oceans.
Hailing the country’s “maritime vocation”, Kast’s government said the bid to host the treaty’s secretariat in the port city of Valparaíso was state policy and testament to its commitment to multilateralism.
“For the government of Chile, it is of high interest to achieve this recognition, and we will carry out all the efforts to obtain the necessary support,” Foreign Minister Francisco Pérez Mackenna was quoted as saying by local media.
Tough competition from Chinese, Belgian bids
But to garner the votes it needs, Chile must fend off competing bids by Belgium – which has proposed its well-connected capital, Brussels – and China, whose well-funded bid includes the provision of free premises in the coastal city of Xiamen and five years of free utility costs.
Parties to the treaty, formally called the Agreement on Marine Biological Diversity of Areas Beyond National Jurisdiction (BBNJ), will choose the headquarters at their first summit (COP1), in New York from January 11 to January 22, 2027. They will seek consensus, falling back on a two-thirds majority in successive secret ballots.
Chile has offered to provide a restored waterside warehouse “at its own expense” as office space, pitching itself to developing countries as a Global South alternative to Europe-centred Brussels. Among richer countries, it is promoting its democratic credentials and greater transparency as an alternative to China.
Rolling back environmental safeguards at home?
While the South American country remains the top pick among environmental campaigners and other civil society groups, critics of Kast’s government say recent policy moves may make it harder for the country to garner the support it needs.
On March 12, the day after Kast took office, the Environment Ministry withdrew 43 decrees awaiting legal approval, including a push to expand the Mar de Juan Fernández and Nazca-Desventuradas marine parks – vast protected areas in Chile’s Pacific Ocean waters. Both remain under review, the ministry told Climate Home News.
The decrees also included an emission standard for coal power plants and regulations for Chile’s new biodiversity and protected areas service.
A month after holding up the decrees, Kast questioned aspects of Chile’s urban wetlands protection law, suggesting it was sometimes an unjustified obstacle to much-needed housing development, and his administration has also sought to ease the rules on salmon farming in the world’s second-largest producer.
In August, the Constitutional Court struck down the salmon farming reform after a challenge by opposition lawmakers and warnings from green groups including Greenpeace, which said it could help farms relocate into protected areas such as the Kawésqar National Reserve.
Valparaíso mayor Camila Nieto, from former leftist President Gabriel Boric’s party, backs the bid to host the High Seas Treaty, but said she hoped “the government’s support also translates into public policies consistent with the goals of protecting and conserving the oceans”.
“The decisions a country makes on environmental matters can influence international perceptions of its commitment to protecting the oceans. That is something we cannot ignore,” Nieto told Climate Home News.

China’s bid stirs concerns over data access, fishing
Chile’s past record on marine protection – it has protected 43% of its jurisdictional waters – could yet give it an edge.
“Chile deserves it for its conservation record as a state. For more than 15 years Chile has been following this path,” Liesbeth van der Meer, executive director at conservation group Oceana in Chile, told Climate Home News.
Concerns in some quarters about the rival bid by China – for example, over a potential conflict of interest due to the vast Chinese fishing industry – may also weigh in Chile’s favour, experts say.
Chinese-flagged vessels did about 30% of detected high seas fishing between 2022 and 2024, according to an Oceana analysis of Global Fishing Watch data. China also sponsors five of the International Seabed Authority’s 31 deep-sea mining exploration contracts, more than any other country.
The secretariat would host sensitive marine data, making transparency paramount, experts say.
China says hosting the secretariat in Xiamen would help make the treaty more globally representative, fostering cooperation between rich and developing countries and aiding equitable access to marine science and technology.
Wang Yi, China’s minister of foreign affairs, said in a statement that the country has “all along championed true multilateralism” and “firmly defended” UN institutions. Given Xiamen’s $38-billion ocean industry, the city lives up to the treaty’s “significance and promising future”, he added.
Meanwhile, Chile is proposing the treaty’s first high seas marine protected area for the Salas y Gómez and Nazca ridges, a chain of more than 110 seamounts stretching about 4,000 km from off Peru to Rapa Nui (Easter Island) that is rich in endemic fish and other marine species.
The ridges are “a true oasis of productivity”, said Carlos Gaymer, director of the Centre for Ecology and Sustainable Management of Oceanic Islands at Universidad Católica del Norte and co-author of a 2021 scientific review of the area.

The water is so clear that phytoplankton thrive around 200 metres down, feeding zooplankton, small fish and, up the chain, sharks and seabirds. Whales, turtles and sharks use the ridges as “a real highway” across the Pacific, Gaymer said. Parts of the Nazca ridge are likely nursery grounds for jack mackerel and swordfish.
Chile has already asked the body that regulates the industry in the area – the South Pacific Regional Fisheries Management Organisation (SPRFMO) – to close the ridges to all fishing vessels. According to Chilean data, more than 80% of fishing in the area involves Chinese vessels.
Meeting on the Chilean request in early September, SPRFMO’s scientific committee agreed only to recommend closing the area to bottom fishing. SPRFMO’s commission will take the final decision at its next meeting, in early 2027.
For Gaymer, Chile’s push to close the area to fishing should be seen as a “starting point” for the treaty proposal.
“Every time there’s a new expedition, species new to science appear,” Gaymer said. “If you don’t protect areas like these … those species simply disappear from the planet.”

Africa should not have to adapt to an unjust climate system
Mohamed Adow is the founder and director of Power Shift Africa.
What does it mean to ask a continent to adapt to a crisis it did little to create? For Africa, that question has stopped being philosophical as it is answered every day in flooded communities, failed harvests, disappearing livelihoods and public budgets stretched by disasters they cannot afford.
Africa produces a negligible share of global emissions, but between 1970 and 2021 it accounted for around 35% of climate-related deaths worldwide. The continent is therefore confronting a brutal contradiction that is exemplified by the fact that those who have contributed least to the climate crisis are carrying some of its heaviest costs.
And that explains why, for us, it is worrying that much of the climate debate treats adaptation as a technical exercise. Build better infrastructure, they say. Improve early-warning systems, they urge. Develop drought-resistant crops, they preach. Strengthen disaster preparedness, they yell. All of these things matter, but they do not answer the harder question of why some people and countries are so much more vulnerable in the first place.
At pre-COP, UN climate chief warns of heat threat to mothers and babies
That is the question we have spent the last couple of years trying to answer, and it culminates in our recently launched thought-provoking report that shows how Africa’s vulnerability is not an accident of geography, but has instead been shaped by history, economics and power.
Colonial extraction, unequal development, debt dependency, global economic asymmetries and exclusion from international decision-making have all constrained the resources and choices available to African countries, and climate change is intensifying those existing inequalities, shows the report, titled “A Just Transition for Adaptation: A Framework and Vision for Africa”.
Widening adaptation finance gap
I say it is ‘thought-provoking’ because it asks us to rethink adaptation itself – not as a collection of projects designed to help people cope with climate impacts, but as a question of justice, power and structural change.
That distinction might not sit well with some people, but for Africa it matters, because there is a danger in asking vulnerable countries simply to become more “resilient”. Resilient against what? How can you ask people to toughen up while letting them be strangled by a system that continues to reproduce the very inequalities that have made resilience so difficult?
If you want to know where the problem is, see where the money is coming from and where it is going. That becomes quite stark when you consider the fact that Africa’s annual adaptation needs are close to $70 billion but its adaptation finance flows are only around $14 billion.

At the same time, a growing proportion of climate finance is being delivered through commercial loans rather than grants. That means countries already under severe fiscal pressure are being asked to borrow to protect themselves from climate impacts they did little to cause.
There is something deeply wrong with a system in which climate-vulnerable countries are spending more of their own public money on adaptation than they receive in international support, because that system turns climate injustice into a financial transaction, with those least responsible carrying more of the cost.
From extractivism to African ownership
And, as the new report shows, the problem goes beyond finance. Africa’s land, minerals, forests and other resources have become central to the global transition towards lower-carbon economies. Markets and green industrial projects may offer genuine opportunities, but without African ownership, participation and accountability, there is a risk that old patterns of extraction will simply be repackaged in the language of the green economy, and that is why we argue that a transition can be low-carbon and still be unjust.
It is precisely because of this risk that the report’s idea of a just transition for adaptation becomes important as it expands the idea beyond the familiar focus on emissions and energy systems. It asks what justice looks like when the goal is not simply to reduce carbon, but to enable societies to withstand a changing climate without reproducing the inequalities that made them vulnerable.
The report places four dimensions of justice at the centre: recognition, participation, distribution and restoration.

Recognition means taking African realities and knowledge seriously. Indigenous and local knowledge has too often been treated as peripheral to “real” climate expertise, even though communities possess generations of detailed understanding of ecosystems, rainfall, soils, water and livelihoods. That knowledge should inform adaptation policy from the beginning, rather than being added after decisions have already been made.
Participation means giving affected communities a genuine voice in decisions about their land, resources and futures. Adaptation governance should be inclusive, democratic, rights-based and rooted in free, prior and informed consent.
Climate justice must confront unequal development
Meanwhile, distribution asks who actually receives adaptation finance, technology and protection? Money that is announced internationally but fails to reach vulnerable communities does little to change their reality.
And, finally, restoration recognises that present-day vulnerability has a history. Climate justice cannot begin and end with today’s emissions, but must also confront the structural conditions that have shaped unequal development and continue to limit African countries’ room to respond.
This report, therefore, is an invitation to change the terms of the conversation on just transition. Africa definitely needs adaptation, but that should not mean endlessly adjusting to an unjust system. The real goal should be something more ambitious; a transition in which resilience, development and justice reinforce one another, shaped by African priorities and grounded in African realities.

At pre-COP, UN climate chief warns of heat threat to mothers and babies
Extreme heat poses a growing threat to pregnant women and their babies, both before and after birth, the UN climate chief said on Monday, calling it “a new faultline in the global climate crisis, and one which is potentially fatal”.
Speaking on the first day of the pre-COP31 meeting in Fiji, where new research was launched on the issue, Simon Stiell warned: “This faultline must not become another deep chasm of climate-driven suffering, inequality and injustice.”
Rather than being a time of hope, he added, pregnancy is becoming “a time of anxiety, as climate impacts fill everyday life with risk”, straining health systems and threatening essentials like food, water and power – especially in poorer countries where many women work outdoors and live in informal housing far from under-equipped clinics.
