Last week, hundreds of scientists, policymakers and journalists flocked to the University of Exeter to attend an international conference on “tipping points”.

The conference saw experts discussing the dangers of a range of Earth system tipping points, including the dieback of the Amazon, the melting of the Greenland ice sheet and the shutdown of the Atlantic Meridional Overturning Circulation (AMOC).

Attendees also explored “positive tipping points” – large-scale, self-propelling social changes that would reduce the impact of humans on the climate.

(For more on the key talking points, new research and ideas that emerged from the four-day event, see Carbon Brief’s full write-up of the event.)

On the sidelines of the conference, Carbon Brief asked a wide range of delegates which tipping point concerns them the most.

These are their responses, first as sample quotes, then, below, in full:

  • Prof Gabi Hegerl: “I am particularly worried about tipping points that involve the biosphere and humans due to breaching thresholds for heat or drought that then ripple into food availability, livelihood and ecosystems.”
  • Prof Carlos Nobre: “The Amazon is a very serious tipping point, because [dieback] could release around 250bn tonnes of CO2 by 2100 – which will make it impossible to [limit global warming] at 1.5C.”
  • Gaia Vince: “I would say that we have already passed the tipping point for coral reef ecosystems…As a scuba diver, I find it a tragedy because I love coral reef ecosystems, but it’s also a tragedy for human systems.”
  • Dr Andrew Hartley: “The tipping point I’m most concerned about is Amazon forest dieback…because of the significance of the carbon cycle and the feedback to the global climate. Also [due to] the effects that Amazon tipping has on food security, both locally and globally.”
  • Prof Tim Lenton: “The Atlantic Meridional Overturning Circulation, or AMOC, for sure. The consequences of crashing that would be devastating globally – and also for where I live in the UK.”
  • Prof Peter Cox: “The one that I’ve worked on most and worries me most at the moment is Amazon dieback. And that’s because we’ve got two things, two stressors, going on at once that push it in the wrong direction. Climate change is one, deforestation is another.”
  • Prof Johan Rockström: “The tipping element that worries me most is coral reef systems, for the simple reason that the scientific uncertainty range is very limited.”
  • Dr Patricia Pinho: “For me, it is the Amazon…I think it’s going to be a really profound, irreversible change that will affect the global population in the most dramatic way.”
  • Prof Ricarda Winkelmann: “I’m mostly concerned about the Greenland and West Antarctic ice sheets. This is because we know that, even at lower warming levels, they are already at risk of transgressing tipping points in certain regions.”
  • Dr Nico Wunderling: “The tipping element that worries me most is the Amazon rainforest. This is because the Amazon rainforest is not only threatened by climate change, but also by deforestation at the same time.”
  • Dr Rebecca Shaw: “The coral reef tipping point…It signals the end of the most colourful and biodiverse ecosystem which supports the nutrition and livelihoods of over one billion people.”
  • Dr David Obura: “The ice [tipping elements] – because they are the first ones to go that have cascading impacts on other tipping elements.”
  • Dr David Armstrong McKay: “The Amazon is actually probably closer to a deforestation-induced tipping point than to a climate change-induced tipping point. So, I actually think that could be potentially in the offing sooner than we would like.”
  • Kate Raworth: “The tipping point that I fear we will fail to cross is [the social tipping point] around transforming our mindsets.”

I am worried about all of them, but for the immediate future, I am particularly worried about tipping points that involve the biosphere and humans due to breaching thresholds for heat or drought that then ripple into food availability, livelihood and ecosystems. The Earth system tipping points will do that too, but maybe a little bit later. Examples [of this] are the coral diebacks triggered by marine heatwaves, forest change and fires, and droughts threatening livelihoods and putting people on the move.

I did a research project on the US Dust Bowl and the trigger [for that event] was drought causing vegetation and crop dieback, [which led to] extreme heat and dust storms in response – and migration, as memorialised in [the 1939 John Steinbeck novel] The Grapes of Wrath. And, now with warming, all droughts get supercharged.

The Amazon is a very serious tipping point, because [dieback] could release around 250bn tonnes of CO2 by 2100 – which will make it impossible to [limit global warming] at 1.5C. We could also lose the largest [host to] biodiversity on the planet, which would induce a tremendous, large number of epidemics and several pandemics. Also, of course, the Amazon forest controls aspects of the global climate. In South America, the climate is entirely controlled by the Amazon forest.

I’m most worried about Amazon [dieback] because I have worked on it for 40 years. But the other tipping points deeply concern me. The melting of the permafrost will release more than 200bn tonnes [of greenhouse gases], mostly methane. Ice sheet melt in Greenland is a very serious tipping point because it could raise sea level rise by three metres in 200 years. The melting of Greenland has already started. Species extinction is also very serious.

One thing that was not much talked about [at this conference] is that when the ocean heats up, particularly the Arctic Ocean, then a tremendous amount of methane is released. And if that happens – if the Arctic Ocean warms up by 3-4C – the amount of methane that would be released could see [air] temperatures reach 8-10C [above pre-industrial levels]. At 8-10C, the only inhabitable places for us humans will be the top of the Alps, the Andes and the north and south poles. The rest of the planet would be uninhabitable.

I would say that we have already passed the tipping point for coral reef ecosystems, for example. That really is a tragedy. As a scuba diver, I find it a tragedy because I love coral reef ecosystems, but it’s also a tragedy for human systems. They are the nursery for our fisheries. And, of course, they’re not just fisheries – they are a valid ecosystem and a biodiversity hotspot. This will have untold consequences and cascading impacts for other parts of the ecosystem, for example, the cycling of nutrients and coral reefs are really important to stop coastal erosion. And they actually provide sand, the lovely white sand that people go on holiday for Bucha.

Dr Andrew HartleyDr Andrew Hartley

The tipping point I’m most concerned about is Amazon forest dieback and reduction in the function of the Amazon forest, because of the significance of the carbon cycle and the feedback to the global climate. Also [due to] the effects that Amazon tipping has on food security, both locally and globally, because of [the Amazon’s] contribution to major commodity markets, such as soybean and maize.

This might interact with climate change in the future to lead to more severe events, particularly in populated areas of Brazil. If an Amazon tipping point were to occur, it might lead to more severe events on the coast of Brazil which would affect a much larger population. There are negative impacts across the forest from the drying of the forest, for example for the Indigenous communities, but also globally.

Prof Tim LentonProf Tim Lenton

Founding director of the Global Systems Institute and chair in climate change and Earth system science at the University of Exeter


The Atlantic Meridional Overtoning Circulation, or AMOC, for sure. The consequences of crashing that would be devastating globally – and also for where I live in the UK. By our own calculation, we could have less than half the viable area for growing a couple of major staple crops, wheat and maize worldwide. We would have a widespread water crisis. We could have collapses of the monsoons in West Africa and India that would displace hundreds of millions of people. It is hard to see that as anything other than a catastrophe.

Prof Peter CoxProf Peter Cox

Professor of climate system dynamics in mathematics and director of the Global Systems Institute at the University of Exeter

The one that I have worked on most and worries me most at the moment is Amazon dieback. And that’s because we’ve got two things, two stressors going on at once that push it in the wrong direction. Climate change is one, deforestation is another. You can imagine crossing the boundary in various ways – but, if you push diagonally, you get there quicker.

If I had spoken to you 25 years ago, I would have said I’m really worried about [Amazon dieback]. Then I went through a phase of thinking that the models have overdone it. And now I’m thinking the models that don’t include land-use change are underdoing it. So, I’m more concerned about that one.

There are others as well, but that is the one that is also quite fast. The other [tipping points] we worry about, we’re worried about a long-term commitment. It takes a while for the AMOC to shut down, it really does. It takes a while for the Greenland ice sheet to melt. We’ve done work that suggests you can overshoot even a little bit for these slow systems. The Amazon forest is a decadal dieback, especially if it is fire driven.

Prof Johan RockströmProf Johan Rockström

Director of the Potsdam Institute for Climate Impact Research (PIK) and professor in Earth system science at the University of Potsdam

There is not a simple answer to this – there is a two-part answer.

The tipping element that worries me most is coral reef systems, for the simple reason that the scientific uncertainty range is very limited. We have, unfortunately, ample evidence that at 1.5C we’re very likely to knock over, potentially, the entire tropical coral reef system on Earth. [This threatens] the livelihoods of 400 million people and a fundamental nursing ground for the whole ocean food web. So that is one deep concern. It is the canary in the coal mine – the first kid on the block to fall over. We’re so close.

The second one is AMOC – the whole overturning of heat in the Atlantic, which connects the entire ocean system. Not only is the latest science showing that we are going from low likelihood to uncomfortably high likelihood, but we also know – with very little uncertainty – that this would cause a catastrophic impact across the entire world, and it would go fast. So the AMOC, I would argue, is today the most important scientific message to the world. If you want a really hard-hitting reason to act at a level of planetary emergency, it is the AMOC. That is the second one.

From a planetary boundary perspective, it is important to recognise that – on climate science grounds – the Amazon basin is not at risk of tipping until 3-5C of warming. But as soon as you factor in loss of biodiversity, deforestation and changes in hydrology – then the temperature risk goes down to between 1.5-2C. So suddenly – when taking a more integrated [assessment] approach – the conclusion is that it is also very close to a tipping point.

Dr Patricia PinhoDr Patricia Pinho

Deputy science director at the Amazon Environmental Research Institute (IPAM)

For me, it is the Amazon. When we think of the planetary crisis, we think about the Amazon and all the regulating climate services it provides. This is not only regionally, but we know it’s a global “climate good”, if you will. But it is highly sensitive to land-use change and increasing temperature. So, if we transition to a point of no return – Amazon dieback – and transforming or transitioning to another ecosystem, the function of the forest will not be doing what it has been doing for the past millennium and so on. And then we cannot revert this loss. I think it is going to be a really profound, irreversible change that will affect the global population in the most dramatic way.

Of course, we have the people on the front line that I’m working with – Indigenous people, traditional population – that are safeguarding this resource, but they are also at the front line of climate risks and the impacts that we already observe. If we miss this opportunity of really reverting from increasing greenhouse emissions and increasing temperature, we’re going to miss the window of opportunity to really protect the region, protect the ecosystem and the forest for the global society.

Prof Ricarda WinkelmannProf Ricarda Winkelmann

Founding director of the Max Planck Institute of Geoanthropology and professor of climate system analysis at PIK and the University of Potsdam

So I am thinking about this from a risk perspective – so both the likelihood as well as the impacts – and I think the answer depends on that. Because when it comes to the likelihood and the particular threshold – and we know about those – I’m mostly concerned about the Greenland and the West Antarctic ice sheets. This is because we know that, even at lower warming levels, they’re already at risk of transgressing tipping points in certain regions.

But when it comes to the impacts and also the timescales over which those play out, there are other tipping elements that worry me most. In particular, regional tipping elements. So if we think of the mountain glaciers, for instance, these impacts are already experienced right now and several mountain glaciers are undergoing these accelerated changes. And so thinking about the timescales when it comes to the impacts is also incredibly important.

Dr Nico WunderlingDr Nico Wunderling

Junior professor at the Center for Critical Computational Studies at Goethe University Frankfurt and researcher at the Potsdam Institute for Climate Impact Research.

The tipping element that worries me most is the Amazon rainforest. This is because the Amazon rainforest is not only threatened by climate change, but also by deforestation at the same time. So that means that the critical threshold from climate change alone, at around 3-4C of global warming, can come down to 1.5-2C. Climate change and deforestation basically go hand-in-hand to lower the [Amazon’s tipping] threshold because of this double threat. 

Dr Rebecca ShawDr Rebecca Shaw

Chief scientist and senior vice-president at WWF

The coral reef tipping point – it comes first because of warming surface waters, and then the outcome is sealed by ocean acidification. It signals the end of the most colourful and biodiverse ecosystem which supports the nutrition and livelihoods of over one billion people and has captured the imagination of more people than any other through the characters like Nemo the clownfish, SpongeBob SquarePants, and, of course, Frank the coral [a character from an educational YouTube video]. 

If humanity is not motivated to act in the face of the loss of coral reefs, is there hope that we will act in time to prevent the Amazon and glacier tipping points?

Dr David OburaDr David Obura

Chair of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services and founding director of CORDIO East Africa

The ice [tipping elements] – because they are the first ones to go that have cascading impacts on other tipping elements. When [ice masses] reduce, we lose their albedo, waters heat up more [and] the AMOC can collapse. That has the biggest impact across the planetary system, including the Amazon.

My own [research], of course, is coral reefs. So, in a way, the coral reef tipping point does concern me the most. [But] it doesn’t have cascading impacts on other tipping elements. It does on people, in socioeconomic terms – but not on other system elements. So, in a sense, it is the least worrying one.

Dr David Armstrong McKayDr David Armstrong McKay

Lecturer in geography, climate change and society in the school of global studies at the University of Sussex and lead author on an influential ​​tipping points assessment, published in Science in 2022

One of the tipping systems that concerns me the most is Amazon rainforest dieback. Because even though we assessed it a few years ago as having a warming threshold that’s a bit higher than what we might be seeing – we’ve thought it is maybe at a best estimate of 3.5C – there’s also deforestation as well. The Amazon is actually probably closer to a deforestation-induced tipping point than to a climate change-induced tipping point. So I actually think that could be potentially in the offing sooner than we would like. That would have huge impacts for biodiversity, for South America as a whole, by shifting rainfall patterns, which would really affect a lot of people for agriculture or ecosystems. Also, the Amazon as an ecosystem is so incredibly biodiverse and amazing in itself, it would be a tragedy to lose it.

The tipping point that I fear we will fail to cross is [the social tipping point] around transforming our mindsets. We need to move from the extractive, degenerative economy towards a regenerative one. This all starts within our head and it underlies everything.

[A failure to do this] is what is driving us towards all these [Earth system tipping points].

Fossil fuel expansion threatens COP31 hosts’ credibility, experts warn

Published

on

Türkiye and Australia risk losing their credibility as hosts of this year’s COP31 UN climate summit if they keep betting on fossil fuels at home, climate policy experts have warned. 

As governments are expected to continue fraught talks over how to advance the global transition away from oil, coal and gas in Antalya this November, both of the co-host countries are pursuing fossil fuel expansion at home, without a national timeline to phase out their use.

Türkiye has accelerated its rollout of wind and solar energy in recent years. But that progress has yet to make a dent in the country’s dependence on fossil fuels for power, as demand growth has outpaced the renewables build-out, new analysis by Climate Action Tracker (CAT) has found.

The share of electricity generated by burning coal and fossil gas – 56% in 2025 – has barely changed since 2019, and total fossil fuel use in the power sector, and the emissions it produces, are still rising, according to the report released on Friday.

The Turkish government has also signalled that fossil fuels will remain a central component of its energy mix and has outlined plans to expand the country’s burgeoning domestic gas production in the Black Sea.

‘Need to demonstrate seriousness’

Australia, which will chair the Antalya negotiations, relies on fossil fuels for over 60% of its electricity, with coal alone still supplying 45%. According to experts, it lacks an ambitious plan to shift away from fossil fuels at home, relying heavily on carbon offsetting to reach its climate targets.

Australia is also the world’s third-largest fossil fuel exporter and has plans to expand its coal and gas production, which is backed by significant government subsidies. It recently upset climate groups by approving an extension of the Saraji open-cut coal mine in Queensland.  

Türkiye says it has “final decision” at COP31 despite Australia running negotiations

Jennifer Morgan, a senior fellow with the Fletcher School of Law and Diplomacy at Tufts University and former climate envoy for Germany, said Türkiye and Australia need to demonstrate their seriousness about their COP presidency roles by leading by example on the energy transition.

“They have made progress in renewable energy,” she told reporters this week. “But I think their credibility – and their ability to therefore bring momentum and good outcomes to the COP – will depend on their taking further action at home.” 

Türkiye’s electrification homework

The co-hosts’ fossil fuel policies are being scrutinised in the run-up to the annual UN climate summit, with much riding on the signal climate diplomacy sends on the energy transition.

Türkiye has so far stopped short of putting any overt political capital behind the fossil fuel transition itself. It has instead been rallying support for a new global electrification target of 35% by 2035, seen as the centrepiece of this year’s non-negotiated Action Agenda put forward by Ankara.

Electrification emerges as COP31 priority

COP31 president Murat Kurum said last week the push to electrify economies – through measures like electric vehicles and heat pumps – will “automatically” lead to a reduction in the use of fossil fuels.

Türkiye’s own energy plan projects the country’s electrification rate would fall short on the global target and only hit 25% by 2035, according to the CAT report, which called for a “substantial step-change” in electrification policies and the deployment of more renewable power and grid infrastructure. 

Coal still dominant

CAT’s analysts also warned that, without a parallel phase-out of fossil fuels, rising electricity demand risks being met in part by coal and gas, failing to deliver the emissions reductions the electrification target is meant to achieve. 

Türkiye has had some success in its clean energy build-out: the share of electricity generation from wind and solar rose to 22% in 2025, up from 12% in 2020, according to the CAT report.

But coal’s role in Türkiye’s electricity mix has also grown, in both its share and absolute terms, over the past decade. And while reliance on fossil gas has declined overall, it still plays an important role in Ankara’s energy policy, which is pushing to boost domestic gas production in the Black Sea.

Dr Niklas Höhne from the NewClimate Institute said the government could demonstrate leadership as COP31 president by building on its recent successes in increasing its renewable energy capacity and announcing targets and plans to phase out coal and gas ahead of the summit.

According to CAT, Türkiye should phase out coal by 2040 and fossil gas by 2045 at the latest to align its power sector with global efforts to limit the rise in global temperatures to 1.5C above preindustrial times. 

Türkiye quiet on fossil fuel roadmap

Ümit Şahin, coordinator of climate change studies at the Istanbul Policy Center (IPM), said Türkiye’s strategy is to approach the fossil fuel debate exclusively from the “end-use point of view”.

“I don’t expect any push from the Turkish presidency to the producer countries in terms of fossil fuel production,” he told reporters.

Neither does Şahin believe the Turkish presidency will throw its political weight behind another big-ticket item for COP31: a new global roadmap to transition away from fossil fuels. 

Brazil took on the responsibility to voluntarily draft this document outside of the formal negotiations as a way to break the deadlock at last year’s UN summit in Belém when governments clashed over whether to develop one. 

The outgoing COP30 presidency will deliver the roadmap in early November – but it will be up to Türkiye and Australia to guide countries towards a decision on how the blueprint will be taken forward, either inside or outside the negotiations.

Leadership needed

Australia’s Chris Bowen, COP31’s president of negotiations, promised to lobby producing countries to deliver a “meaningful step forward” on the fossil fuel transition in an interview with The Guardian earlier this year. But he has been quiet on the role Australia sees for the fossil fuel transition roadmap. 

Natalie Jones, senior policy advisor at the International Institute for Sustainable Development (IISD), said the COP31 co-presidents “must provide clear leadership” on this process.

“This roadmap cannot be left in a dusty drawer,” she told journalists. “Rather, it must be translated into action, with all countries identifying what elements they can adopt or develop in their own national roadmap.”

    Like Türkiye, Australia has yet to produce a national blueprint for winding down coal, gas and oil. Rather than moving toward a phase-out, state and federal governments have kept expanding fossil fuel licensing over the past year, according to a new analysis published this month by Climate Analytics.

    Under existing policy, both coal and gas are on track to remain in Australia’s power system as late as 2050 – a trajectory the report defines as incompatible with the 1.5C limit the country says it’s committed to. 

    No binding end dates for the Netherlands

    Analysts are watching out for national transition roadmaps as a bellwether for governments that claim to be leaders in the global shift away from fossil fuels.

    The Netherlands, which co-hosted the first fossil fuel transition conference in Santa Marta this year, published its own domestic roadmap earlier this week. The document followed through on a pledge that “leadership on transitioning away from fossil fuels must be backed by concrete action, not just ambitious words”, said a spokesperson for Stientje van Veldhoven, the Dutch minister for climate policy.

    But experts criticised the plan for failing to set a binding end date for the country’s fossil fuel production and use. While targeting a rapid increase in renewables capacity, the Dutch government only commits to phasing out oil, gas and coal “in the energy and feedstock system to eventually zero, and to minimise fossil use” by 2050. 

    Yvo de Boer, a former Dutch diplomat and executive secretary of the UN climate body, said the Dutch roadmap falls short of what’s needed to give industry the confidence to deploy capital in support of the energy transition with greater predictability. 

    “Ultimately, a roadmap without deadlines is nothing more than a footpath paved with good intentions,” he added, writing on LinkedIn.

    How clean energy can boost business for Africa’s food producers

    Published

    on

    Despite millions of dollars in grants and technical help for African businesses to power farming and other food production activities with renewable energy, most efforts remain stuck at the early stages because they struggle to find the investors, markets and expertise they need to grow.

    This was the message from a coalition of global institutions working on energy, water and agriculture at this month’s Africa Food Systems Forum in Kigali, Rwanda.

    “Energy, agriculture, water and nutrition actors rarely design solutions together,” the Agri-Energy Coalition said in a Call to Action on powering food systems with clean energy.

    Using more renewables – especially solar power – to drive food systems would reduce food losses, ensure year-round availability and affordability of healthy foods, and improve productivity, income and resilience among farmers, food processors and other small enterprises, the coalition added.

    In an interview with Climate Home News at the forum, Olamide Niyi-Afuye, CEO of the Africa Minigrid Developers Association (AMDA) – a body representing private-sector developers of small-scale, off-grid electricity systems across the continent – said its members are starting to recognise this interdependence and are increasingly considering businesses that combine energy with agricultural activities.

      This, Niyi-Afuye added, could lead to greater supply and use of clean power for key processes like irrigation, food processing and storage, creating new sources of revenue for both sectors.

      CHN: Conversations at the Africa Food Systems Forum highlighted how organisations working in energy and agriculture often operate in silos. What has hampered their collaboration, and how has that affected Africa’s economic development?

      A: Most mini-grid companies in Africa were primarily incentivised to achieve connections. If you look at some ongoing projects, you see a cost-per-connection model [of revenue]. When a subsidy is tied to achieving a connection, regardless of whether it is a productive connection, you might not notice the problem until five years down the line, when you realise the cash flows are not what you projected.

      Despite African walkout, fractious land COP ends without drought deal

      So now we’re in a “come-to-Jesus moment” as an industry, where we’re righting the wrongs and adjusting our business models to make sure companies do not go bust and there is some level of sustainability over the long term.

      The saying is not wrong that we’ve been working in our own silos because we’ve focused on the smaller things instead of the helicopter view. There needs to be cross-pollination [between the energy and agriculture sectors] because, if we are thinking about industrialisation, energy is a key driver of industrialisation. We will not achieve that if we’re not in the room and part of those conversations.

      CHN: Productive use of energy is intended to ensure electricity access goes beyond lighting homes to improving livelihoods, creating jobs and powering equipment. But what happens when farmers cannot afford the equipment they need to do that? How can energy, agriculture and equipment players work together to make the transition more accessible?

      A: That’s why we’re having conversations with companies set up to de-risk the agriculture sector. By leveraging that connection, we’re able to aggregate potential energy needs and develop instruments that make equipment more affordable through bulk procurement.

      We can have arrangements that make it easier for farmers and food producers to lease equipment and eventually own it over a period. There’s no real pressure to recover the capital very quickly because you’re looking at scale.

      There is a whole lot across the agricultural value chain that needs energy, from farming and harvesting to food processing and value-addition. We need to understand the energy needs across the value chain and bring our members in to provide solutions.

      Developers do not necessarily need to provide every productive-use solution themselves. They can partner with equipment suppliers, financiers, agribusinesses and other service providers to enable customers to use electricity productively. The objective is simple: do not just electrify communities; enable economic activity that uses that electricity.

      CHN: When Africa’s industrialisation is discussed, you hear things like renewables cannot provide enough baseload, while some food processors are sceptical about switching to renewable energy because of these concerns about reliability. What is your response?

      A: It’s not a controversial statement to say that a typical baseload is usually from the grid, and it’s usually from multiple sources including renewable energy. For large-scale operations, we can look at blending multiple sources of energy. But how do we solve the problem of a mid-sized farmer? We can solve it with a mini-grid using renewable energy.

      Comment: Every country needs a model to help optimise its energy transition

      If you go to a small farmer in a rural area, they don’t care about what source of energy they’re getting. They just want something that can help them get from A to B. If you look at the direct energy needs of farmers and food processors, I’m sure 90 percent of their consumption can be solved by renewable energy. Let’s start with that problem first. Then, as they scale, they might need to ramp up, and we can start talking about a bigger baseload.

      CHN: How much agricultural value is lost because farmers and food businesses lack reliable, affordable electricity?

      A: If you look at, for example, the fact that we need to maybe plant tomatoes or strawberries in Jos before it gets to Lagos [Nigeria], which most likely is by road, I can assure you that a good chunk, if not stored properly, would be bad by then. So the fact that we do not have energy is in itself a lost opportunity to maximise the potential of the agriculture sector. So until we’ve solved the energy problem, we will not salvage waste – and for me that is a lost opportunity.

      CHN: AGRA, an institution focused on scaling agricultural innovations to help smallholder farmers, estimates a massive shortfall between current investments in the continent’s food systems and what is actually needed to build a resilient, profitable agricultural economy – to the tune of $180 billion per year. Can integrating energy into food systems help bridge that gap?

      A: Yes – if energy can help unlock the potential to earn more money, investors will follow the money. Investments go where there is certainty, and until there is certainty around cash flow and revenue, investment will be limited.

      My vision is to see more Power Purchase Agreements (PPAs) being signed between energy players and the agriculture sector. We can start by getting people into the room, understanding their pain points, crafting a framework and documentation that works for both parties, and then seeing deals happen.

      Human security relies on adapting to the world’s new climate reality

      Published

      Cristina Rumbaitis del Rio is a senior advisor on adaptation and resilience with the United Nations Foundation and Mattias Söderberg is global climate lead at Danish NGO DanChurchAid.

      Recent extreme events – from wildfires and heatwaves in Europe to flash flooding following a glacier collapse in Nepal – have shocked and devastated communities, bringing years of warnings about such climate impacts to the doorstep of communities around the world.

      One thing is certain: the new climate reality is here – and the adaptation strategies designed for yesterday’s world are no longer sufficient.

      Attribution science has since shown that the hotter and more frequent heatwaves we’re experiencing around the world would have been virtually impossible without today’s high concentrations of greenhouse gases in the atmosphere. Climate shocks are now so severe that they reverberate through supply chains, food and water systems, financial markets and the movement of people.

        They must be a catalyst for a new way of thinking about adaptation and resilience, and how we finance solutions that work. A failure to invest in adaptation in one region can create costs far beyond it, which is why the concept of shared resilience is critical for leaders to grasp.

        Investment not charity

        At the UN General Assembly (UNGA 81) this month, leaders have an opportunity to translate today’s urgency into concrete commitments on adaptation and loss and damage finance ahead of COP31.

        Those commitments are needed to underpin global stability, shared prosperity and human security. Governments should use this moment to show what a new response looks like: finance that reaches communities faster, supports locally grounded solutions, strengthens national systems, and helps countries prepare before the next shock arrives.

        If we want sustained economic growth, food and water security, and resilient and prosperous societies across every region, adaptation must be at the heart of today’s development and security agenda. It cannot be just a future planning consideration or a narrow issue for climate ministries. Adaptation is now everyone’s business – and it must be financed fast and fair.

        UN Secretary-General António Guterres has repeatedly framed climate finance as an investment rather than charity, warning that “a world in climate chaos cannot be a world at peace” and describing human security as freedom from the chronic and sudden disruptions that climate change multiplies.

        What’s more, adaptation delivers a real return-on-investment, with researchers estimating that every dollar invested produces $10 in benefits, saving lives, protecting livelihoods, and reducing the costs of future disasters.

        Hitting adaptation limits

        The urgency to scale adaptation systematically is growing. The newly released “Limiting Overshoot” report from the UN Environment Programme (UNEP) confirms what scientists have long warned: exceeding global warming of 1.5C is now unavoidable under current policies. Yet, how high temperatures rise – and how long the world remains above the 1.5C threshold – will determine whether communities, economies and entire ecosystems can keep pace.

        There are limits to adaptation. When we breach those limits, lives and livelihoods are lost, and people and ecosystems suffer greatly. We cannot simply build yesterday’s infrastructure a little stronger and assume it will be enough.

        We need to fundamentally change the systems that determine how societies anticipate, absorb and recover from both immediate and evolving non-linear climate shocks. This includes transforming physical systems, such as infrastructure, and the governance systems that affect where and how we live to how we maintain our health and wellbeing.

        Finance today is nowhere near the scale of the challenge.

        The UNEP “Adaptation Gap Report 2025” estimates the shortfall in adaptation finance in developing countries at $284 billion–$339 billion a year – roughly 12 to 14 times current international public flows of around $26 billion. That gap is a development, economic and human security problem, especially for the most vulnerable populations who have contributed the least to causing the climate crisis.

        Building resilience into financial systems

        There are already signs of what a more systemic adaptation response could look like. Communities around the world are delivering practical solutions at local level, even as adaptation finance remains notoriously, and appallingly, difficult to access. Cyclone-resistant homes, local forecasting capacities, drought-resistant crops, heat insurance for pregnant informal workers and mangrove restoration are rooted in local knowledge and lived experience, while delivering benefits far beyond the communities where they originate from.

        But local innovation alone is not enough; the systems around it need to be resilient too.

        Jamaica offers one example. The country has built a multi-layered disaster-risk financing framework, including a catastrophe bond and contingency funds, through sustained fiscal discipline and proactive investment. Its debt-to-GDP ratio fell from around 147% in 2012 to around 62% in 202-25. That groundwork matters when disaster strikes.

        Hurricane Melissa’s destruction shows need for climate resilience push

        Following Hurricane Melissa, Jamaica was able to secure billions of dollars in reconstruction financing from multilateral banks – finance that might otherwise have been much harder to access. The lesson is clear: resilience can be built into the financial architecture of a country before a crisis arrives. That is the shift we now need to make at scale.

        The foundations already exist – in Kingston’s fiscal reforms, in early-warning systems from the Sahel to the Pacific, and in every community that adapted before disaster struck. What is still missing is the political will, and the finance, to take what works and put it to work everywhere, at the speed our world’s new climate reality demands.
