Many communities are vulnerable to climate shocks – from the urban poor in Brazil to smallholder farmers in Africa’s Sahel region. But few are more vulnerable than those living in Small Island Developing States (SIDS) around the world, from the Caribbean to the South Pacific.
Storms and rising sea levels present an existential risk. They can wipe out annual incomes several times over. We don’t yet know the full extent of the damage wrought on Jamaica by Hurricane Melissa – the strongest hurricane to hit the island since records began – but they are expected to run into tens of billions of dollars, and recovery will take at least a decade.
These nations are the “canaries in the coal mine”, signalling the dangers that lie ahead. In 2022, the world set out a plan to tackle the threat. Economists, nonprofits and nation states got behind the Bridgetown Initiative, spearheaded by Barbadian Prime Minister Mia Mottley.
It has historically been difficult and expensive to finance the projects many nations need to cope with our changing climate. Yet much progress has been made on the Bridgetown Initiative’s five-step plan to reform the global financial system.
We have seen wider adoption of pause clauses in debt arrangements aimed at taking the pressure off countries when they face disasters. These clauses were used for the first time by Grenada and St. Vincent and the Grenadines in the aftermath of Hurricane Beryl in 2024. In 2023, countries agreed to unlock $100 billion in Special Drawing Rights, an international reserve of assets held by the International Monetary Fund (IMF), scaling up states’ efforts to build resilience to climate change.
More recently, progress has been made to reduce the cost of capital and currency volatility, two other major brakes on resilience investments. Brazil, the COP30 host nation, has just launched the Eco Invest programme with the Inter-American Development Bank (IDB), which will mobilise significant new private and public finance to restore degraded rural areas, produce clean energy and create green jobs.
Closing the yawning climate finance gap
These measures have helped to close a yawning climate finance gap, but more action is needed.
Global average temperatures continue to rise, and we are close to biophysical tipping points with disastrous consequences. For many climate-vulnerable countries, investing in resilience is the best response. Climate adaptation technologies have improved substantially and countries can now build heat-ready homes and schools, while coastal defences can withstand Category 5 hurricanes like Melissa. Every dollar spent on adaptation saves up to $10 on avoided losses.
The investments that have the greatest savings tend to be public goods, such as sea walls and flood defences, with few capturable revenues for private investors. The private sector has an important role to play in developing resilience technologies and implementing resilience investments, but 90% of the time, the public sector ends up paying.
Many call on rich nations to provide more grant support for the climate vulnerable. But grants are shrinking, so we must consider other ways to unlock more investment.
Climate adaptation can’t be just for the rich, COP30 president says
First, the major players who influence debt sustainability – ratings agencies such as Fitch and Moody’s, private investors, the IMF, the World Bank and other multilateral development banks (MDBs) – could change their approach. Too often, the risks of climate shocks are priced into debt repayments without considering the opportunity to gain by making countries more resilient to them. This makes it harder for countries to do the right thing.
Second, the most climate-vulnerable nations will need new borrowing instruments that are low-cost, long-term and flexible, for example ensuring that debt interest repayment timings can be adjusted if a disaster such as a devastating hurricane strikes.
Because of their AAA credit ratings, MDBs like the World Bank are best positioned to help. Small island nations require an estimated $36 billion for adaptation efforts but received a fraction of that last year, and the World Bank and Inter-American Development Bank (IDB) have committed to raising their adaptation finance portfolio overall to 50% of climate finance, up from 30%.
Third, climate-vulnerable countries are still paying a huge portion of their tax revenues in servicing debt. More can be done to break this vicious cycle, and one solution is something called a debt-for-resilience swap. That’s when a AAA-rated guarantor guarantees the debt of a climate-vulnerable country, allowing it to borrow at significantly lower interest rates. The proceeds are then used to buy back expensive debt – keeping the level of debt unchanged, but re-routing interest savings for resilience investments. Barbados, the Bahamas and Ecuador have done debt-for-climate swaps, but guarantors are in limited supply.
Comment: Can COP30 mark a turning point for climate adaptation?
To tackle this challenge, the IDB and other MDBs are developing the first-of-its-kind Multi-Guarantor Debt for Resilience Facility, where multiple guarantors work together to unlock more debt swaps on a larger scale.
In these difficult times, when climate change is driving ever more dangerous and unpredictable impacts in vulnerable places, we must press forward with further reforms. Bridgetown has already channelled hundreds of billions into building stable countries with a secure future – something that benefits all of us. Now we all need to raise our adaptation ambitions.

Climate Change
Women must be a starting point, not an afterthought, for adaptation
Alexandria Gordon is manager of policy and development at the Women’s Environment & Development Organization) and Demet Intepe, PhD, is a climate adaptation and resilience expert with Practical Action.
If the world genuinely intends to help people adapt to climate change, including women cannot be treated as optional. It must be the starting point for every plan and policy.
Across the Global South, climate impacts are already reshaping daily life. Floods, droughts and heatwaves are destroying homes, crops and livelihoods.
Evidence consistently shows that when women and girls participate fully in adaptation efforts, entire societies benefit. Putting gender at the centre makes adaptation stronger, more equitable, and more sustainable.
COP30 was expected to cement this understanding. Touted as “the COP of Adaptation,” it fell far short. Once again, decisions were made without meaningful consideration for the people already facing the harshest climate impacts. Communities trying to protect their homes, harvests and livelihoods are still denied the resources and action they urgently need.
“Coordinated backlash”: Activists say COP30 gender spat reflects wider threat
The UN Environment Programme’s annual Adaptation Gap Report outlines the scale of investment required to address escalating climate risks. What remains missing is political will – the willingness to respond to communities already facing loss, and to acknowledge that adaptation fails without women because it ignores half the knowledge and leadership societies depend on.
Women are central to decisions about land, food, water, care and community organising on farms, in markets, in local government, cooperatives or social movements. When their rights, voices and priorities are excluded, policies address only part of the risk, funding bypasses those best placed to use it, and solutions fail to reflect how communities actually adapt.
Women leading adaptation on the ground
Purnima Rani Biswas in Bangladesh rebuilt her livelihood after Cyclone Amphan devastated her village in 2020. When floodwaters finally receded, she and her community received training to restore their fields and strengthen resilience. Purnima began growing crops on elevated dykes above future flood levels.
Her success inspired neighbours, proving that farming on shifting, flood‑prone land is possible. Recovery has been slow, but the community now believes adaptation is achievable.
Saraswati Sonar, chair of her local Community Disaster Management Committee in Nepal, plays a crucial role in keeping her community safe. She regularly contacts government hotlines for weather updates and alerts elderly people, pregnant women, and families with young children when evacuation is necessary. Her leadership ensures timely, life‑saving action.
These examples show that women are not passive victims of climate change - they are active agents of resilience.
What gender‑responsive adaptation really means
Language shapes action. Terms like “gender‑sensitive” often become symbolic rather than transformative. “Gender‑responsive,” however, demands concrete action. It means:
- Integrating gender as a priority across planning, budgeting, implementation, and monitoring
- Recognising unequal access to land, income, technology, mobility and decision‑making, and how these shape people’s ability to adapt
- Acknowledging who grows food, collects water, rebuilds homes, and who is left behind during crises.
Gender-responsive adaptation is not about elevating women above others. It is about making climate policy effective. Without women, climate action fails – and risks deepening existing inequalities rather than reducing vulnerability.
Yet at COP30, some governments resisted the term “gender-responsive,” preferring weaker language that allows them to avoid meaningful commitments to equity and justice.
What COP30 achieved and where it fell short
Despite major shortcomings, COP30 delivered a few important steps for gender and adaptation. A new Gender Action Plan was adopted, intended to help mainstream gender across national plans and global policies. Its impact will depend on whether governments implement it meaningfully.
Under the Global Goal on Adaptation, countries adopted 59 indicators to track progress, including a gender-specific indicator. This is a significant step forward: for the first time, global reporting will show whether national adaptation policies are genuinely gender-responsive.
Tripling adaptation finance is just the start – delivery is what matters
However, progress was uneven. National Adaptation Plans moved in the wrong direction, with gender commitments weakened and made conditional “only when applicable”, rather than central. This risks sidelining gender entirely unless civil society holds governments to account.
Adaptation finance was COP30’s biggest failure. The decision to “triple adaptation finance by 2035” remains vague and falls short of meeting adaptation needs. The Adaptation Fund, a leader in integrating gender into climate finance, received pledges of only around $135 million – less than half its $300 million target. Without predictable, grant-based finance, even the strongest plans cannot reach the communities that need them most.
What needs to happen next
Real adaptation happens in homes, fields, forests and coastal villages, not in negotiation rooms. Communities living through climate impacts already know what works. Community‑led, gender‑just approaches consistently reduce climate risk and build resilience.
To turn the Gender Action Plan’s commitments into action, governments must:
- Make gender-responsive adaptation non‑negotiable
- Invest in locally led solutions that prioritise community leadership and women’s intergenerational knowledge
- Ensure finance reaches frontline communities without creating new debt
- Use the GGA indicators to strengthen transparency and accountability
Organisations such as the Women’s Environment and Development Organization and Practical Action already work with communities using rights-based, gender-just approaches that reflect local needs and priorities. It is crucial for organisations that work directly with most impacted communities to be part of conversations on adaptation, including countries’ policy development.
From commitments to action
For COP decisions to matter, they must translate into action on the ground. Adaptation can no longer remain the slow lane of climate action, and gender can no longer be sidelined. Every global decision and national action must now be intentionally gender-responsive.
Why adaptation fails without women is no mystery. The question is who will act on what we already know?

Bridging Knowledge Systems: Indigenous Nations and Academia Collaborate on Climate Research in Canada
On the tundra in Inuit Nunangat, an Elder kneels by thinning sea ice, pointing to the cracks forming earlier each spring. Nearby, community youth work with researchers to set up monitoring equipment that tracks ice thickness, temperature shifts, and permafrost thaw. Together, they are documenting climate change not from separate vantage points, but in conversation, where Inuit knowledge of the land and Western science meet.
Across Canada, such collaborations are on the rise. Indigenous Nations and academic institutions are joining forces to confront climate change, weaving together Indigenous ways of knowing with scientific methods. These partnerships hold immense promise: they deepen understanding, inform adaptation strategies, and strengthen resilience for both Indigenous and non-Indigenous communities. But they also raise urgent questions about ethics, ownership, and how to move beyond colonial legacies that have historically extracted and exploited Indigenous knowledge.
The Promise and Pitfalls of Collaboration
When done respectfully, Indigenous–academic partnerships generate knowledge that neither system could produce alone. Indigenous expertise, rooted in millennia of relationship with land, water, and sky, offers insights into biodiversity, ecosystem health, and patterns of climate change that Western science is only beginning to measure. Meanwhile, academic research provides tools like data modelling, satellite mapping, and policy advocacy that can elevate Indigenous voices in national and global decision-making spaces.
Yet the pitfalls are significant. Indigenous intellectual property (IP), the stories, practices, symbols, and innovations that belong to Indigenous Peoples, has too often been taken without consent, acknowledgment, or benefit. In Canadian history, knowledge of plants, medicines, and land-use practices has been extracted and patented, leaving communities with nothing but loss and mistrust. These harms are not distant memories; they shape the caution and hesitation many Indigenous Nations feel when approached by universities today.
For Indigenous communities, protecting IP is not only about legal safeguards. It is about sovereignty: the right to control how knowledge is shared, by whom, and for whose benefit. Without this, collaboration risks reproducing the very colonial patterns it claims to resist.
Academia’s Growing Commitment to Ethical Partnerships
Thankfully, many Canadian academic institutions are beginning to come to terms with this history and adopt new approaches to research. Universities are developing frameworks and policies that embed principles of respect and accountability, such as:
- Free, Prior, and Informed Consent (FPIC): Research can only proceed with the voluntary and fully informed agreement of Indigenous Nations.
- Respect for Indigenous data sovereignty: Communities must control how data is stored, accessed, and used.
- Co-creation of research questions and methods: Projects must be shaped together, not imposed by academics.
- Equitable sharing of benefits and authorship: Indigenous collaborators must be credited and compensated fairly.
- Long-term accountability: Partnerships should outlast funding cycles and continue to serve community priorities.
This shift is not perfect, nor is it complete. But the trajectory is encouraging: Indigenous governance and ethics are increasingly central to climate research in Canada.
Consequences of Collaboration: Good and Bad
The outcomes of these partnerships are not abstract. They have real consequences for climate action on the ground. Where research has gone wrong, communities recall sacred sites being surveyed without consent, knowledge of medicinal plants being patented for corporate use, and environmental studies that used Indigenous stories but excluded Indigenous voices from authorship. These failures reinforce mistrust and make communities wary of outsiders.
By contrast, when done well, collaboration strengthens both knowledge and resilience. For example:
- The Kainai Nation and the University of Calgary collaborate on drought adaptation, combining climate modelling with traditional food system knowledge to develop locally grounded strategies.
- The Tłı̨chǫ Government and Carleton University are monitoring permafrost thaw in the Northwest Territories, where Indigenous knowledge guides interpretation while scientific tools quantify the scale of change.
- The Anishinabek Nation and Lakehead University collaborate to restore wild rice beds, combining ecological monitoring with stewardship practices that sustain both ecosystems and culture.
These projects illustrate what is possible when Indigenous leadership is respected and academic expertise is aligned with community priorities.
Youth, Future Generations, and the Global Context
Collaboration is not only about research results, but also about building capacity for future generations. Training Indigenous youth in both traditional and scientific methods ensures continuity of stewardship and opens pathways into climate sciences, data analysis, engineering, and policy. This intergenerational transfer is critical, as it is young people who will live most directly with the consequences of climate change.
Canada is not alone in this work. Around the world, Indigenous communities are leading partnerships with academia. Māori researchers in Aotearoa, New Zealand, develop coastal restoration strategies grounded in whakapapa (genealogy), and Sámi leaders in Scandinavia combine herding knowledge with climate models to track changes in snow and migration patterns.
Canada has an opportunity and a responsibility to lead globally by embedding Indigenous governance within research institutions and climate policy.
What Indigenous Communities Should Consider
When invited into research collaborations, Indigenous Nations should feel empowered to set terms, ask questions, and safeguard their knowledge. Key considerations include:
- Consent: Has Free, Prior, and Informed Consent been obtained, clearly and respectfully?
- Intellectual Property: Who owns the data and knowledge? How will it be used, stored, and protected?
- Community Benefit: Does this project address our priorities and bring tangible benefits to our people?
- Co-creation: Were we part of shaping the questions and methods, or are we being slotted into a pre-existing framework?
- Cultural Protocol: Are researchers prepared to follow our laws, ceremonies, and privacy requirements?
- Data Sovereignty: Will data remain under our governance?
- Capacity Building: Will this train our youth, employ our people, or build local expertise?
- Publication Rights: Do we have control over how findings are published, and will our members be acknowledged as co-authors?
- Exit Plan: What happens when the project ends? Will knowledge, data, and benefits remain with us?
These questions are not barriers; they are safeguards to ensure collaboration is ethical, reciprocal, and grounded in Indigenous sovereignty.
Strengthening Indigenous–Academic Partnerships
To move forward, Canada must think beyond project-by-project partnerships and build systemic change built in true collaboration with Indigenous-led initiatives such as:
- Embedding Indigenous governance in research ethics boards.
- Supporting Indigenous-led research universities and centres of excellence.
- Creating funding streams that prioritize Indigenous research sovereignty.
- Establishing national policy frameworks to protect Indigenous knowledge.
- Formalizing spaces for reciprocal knowledge exchange that place Indigenous and Western knowledge systems on equal footing.
These steps shift collaboration from a transactional to a transformational approach.
A Call to Action
The convergence of Indigenous knowledge and academic research offers immense promise in confronting climate change. Together, these systems can generate insights grounded in centuries of relational stewardship and sharpened by scientific rigour. But true collaboration demands more than goodwill. It requires dismantling colonial patterns, affirming Indigenous intellectual sovereignty, and ensuring that research benefits the lands and peoples from which it arises.
To academia: move beyond consultation and share governance of research with Indigenous Nations.
To governments: fund Indigenous-led research and respect Indigenous sovereignty in climate policy.
To Indigenous Nations: know your power, set the terms, protect your knowledge, and demand reciprocity.
The path forward shines brightest when Indigenous and academic knowledge systems walk side by side. If Canada adopts this model, the future will not only be more just, but also more resilient for the land, the waters, and future generations.

“New era of climate extremes” as global warming fuels devastating impacts in 2025
In 2025, greenhouse gas emissions produced by human activities turned what should have been a cooler year into one of the hottest ever, fuelling more dangerous and frequent heatwaves, droughts, storms and wildfires, climate scientists said in an annual report.
Planet-heating emissions primarily caused by burning fossil fuels pushed temperatures this year to “extremely high” levels, worsening extreme weather with devastating consequences – especially for the world’s most vulnerable, concluded scientists working with the World Weather Attribution (WWA) group.
Despite the return of La Niña – a climate pattern linked to large-scale cooling of the Pacific Ocean, which can temporarily bring milder global temperatures – the EU monitoring service Copernicus has said 2025 is “virtually certain” to end as the second- or third-warmest year on record.
In its report released on Tuesday, the WWA research group found that climate change made 17 of the 22 extreme weather events it assessed this year more severe or more likely, while its remaining studies were inconclusive, mostly due to a lack of weather data from remote areas.
Ranging from heatwaves in South Sudan and Western Europe to extreme rainfall in Southeast Asia and wildfires in Los Angeles, those disasters killed thousands of people and displaced millions from their homes.
11 extra hot days since Paris Agreement
Theodore Keeping, a researcher at Imperial College London, said the catastrophic wildfires, record-breaking rainfall, unprecedented temperatures and devastating hurricanes seen in the last 12 months provide “undeniable evidence” of a rapidly changing global environment.
“We are living in the climate that scientists warned about a decade ago, when the Paris Agreement was signed,” he added.
Since the landmark accord was adopted in 2015, global average temperatures have risen by about 0.3C, and the world now experiences an average of 11 additional hot days each year, according to WWA’s research.
For the first time, global average temperatures over the last three years are on track to exceed 1.5C, the most ambitious goal governments agreed in Paris, according to the EU’s Copernicus service. The UK’s Met Office expects 2026 to be between 1.34C and 1.58C hotter than preindustrial levels.
“The continuous rise in greenhouse gas emissions has pushed our climate into a new, more extreme state, where even small increases in global temperatures now trigger disproportionately severe impacts,” said Sjoukje Philip, a researcher at the Royal Netherlands Meteorological Institute (KNMI). “We are entering a new era of climate extremes, where what was once an anomaly is quickly becoming the norm,” she added.
Silent-killer heatwaves
While heatwaves don’t leave a visible trail of destruction and often go underreported, the research group found they were the deadliest extreme weather event of 2025. One study estimated that climate change more than tripled the number of deaths caused by searing temperatures recorded across Europe this summer.
In South Sudan, extreme heat forced schools to close for two weeks in February 2025 after dozens of children collapsed with heatstroke. Human-made climate change made that heatwave 4C hotter and transformed an exceptionally rare event into a common one, now expected to happen every other year in South Sudan, a WWA assessment found.
Keeping of Imperial said the impacts are disproportionately shouldered by women and girls who predominantly work in sectors with high heat exposure such as agriculture and street-vending.
Flood risks rise as adaptation limits near
Floods were the disasters most studied by the WWA team in 2025, with devastating downpours made worse by climate change hitting Pakistan, Sri Lanka and Indonesia, the Mississippi River Valley in the US and Botswana.
In the Southern African nation, spells of extreme rainfall are becoming more frequent within a single year, while the rapid expansion of urban centres without adequate infrastructure upgrades makes them more susceptible to severe flooding, according to WWA.
The research group said this underscores the urgency of investing in measures to adapt to a warming world which can prevent many deaths and widespread destruction but remain critically underfunded.
However, the scientists also warned that even strong efforts to prepare for disasters cannot prevent all impacts, as climate change is already pushing millions close to the “limits of adaptation”.
“Jamaica was in a state of preparedness for Hurricane Melissa five days before landfall,” noted Keeping, “but when such an intense storm hits a small island nation in the Caribbean, even high levels of preparedness cannot prevent extreme losses and damages”.
Fossil fuel dependency is “costing lives”
Hurricane Melissa caused an estimated $8.8 billion in physical damage in Jamaica, equal to 41% of the country’s 2024 GDP, with only a small share of the losses expected to be covered by innovative insurance schemes.
In their report, WWA researchers said that drastically reducing fossil fuel emissions remains the key policy to prevent the worst climate impacts.
“Decision-makers must face the reality that their continued reliance on fossil fuels is costing lives, billions in economic losses, and causing irreversible damage to communities worldwide,” said Friederike Otto, WWA’s co-founder.
