United Nations Secretary-General António Guterres issued a “global SOS” from Tonga urging governments to step up climate action to “Save Our Seas” as two new reports revealed how rising sea levels are threatening the vulnerable region and beyond. 


He was speaking at the Pacific Islands Forum, which consists of 18 Member States, from Australia to Vanuatu. The PIF is guided by a long-term vision and a 2050 strategy for ensuring the health and wellbeing of all by working together “to leverage our collective strengths and build a better future.”

Mr. Guterres told the annual gathering that the global 2030 Agenda for Sustainable Development – built around the 17 Goals or SDGs – “is faltering”.

“This is a crazy situation: rising seas are a crisis entirely of humanity’s making. A crisis that will soon swell to an almost unimaginable scale, with no lifeboat to take us back to safety,” he warned.

“But if we save the Pacific, we also save ourselves. The world must act and answer the SOS before it is too late.”

Unprecedented sea level rise

The UN chief said global average sea levels are rising at rates unprecedented in the past 3,000 years.

“The reason is clear: greenhouse gases – overwhelmingly generated by burning fossil fuels – are cooking our planet. And the sea is taking the heat – literally,” he continued.

Seas have absorbed more than 90 per cent of global heating in the past five decades.  Water expands when it gets hotter, and melting glaciers and ice sheets have added to the sea’s volume, causing the ocean to overflow.

Ocean changes accelerating

Two UN papers published that day “throw the situation into sharp relief”, he said.

The study by the World Meteorological Organization (WMO) on the State of the Climate in the South West Pacific, alongside a report by the UN Climate Action Team on Surging seas in a warming world, “show that changes to the ocean are accelerating, with devastating impacts.” 

Together, they outline how monthly sea temperatures continue to shatter records. At the same time, marine heatwaves have become more intense and longer lasting, doubling in frequency since 1980, while rising seas are amplifying the frequency and severity of storm surges and coastal flooding.

Pacific islands ‘uniquely exposed’

“Today’s reports confirm that relative sea levels in the Southwestern Pacific have risen even more than the global average – in some locations, by more than double the global increase in the past 30 years,” the Secretary-General said.

He explained that “Pacific islands are uniquely exposed” as average elevation is just one to two meters above sea level, around 90 per cent of people live within five kilometres of the coast, and half of all infrastructure is within 500 metres of the shoreline.

Without drastic cuts to emissionsthe Pacific Islands can expect at least 15 centimetres of additional sea level rise by mid-century, and more than 30 days per year of coastal flooding in some places,” he said.

The reports revealed that the average rate of sea level rise has more than doubled since the 1990s, indicating that “the phenomenon is accelerating in an unusual and uncontrolled way.” 

While global-mean sea level has risen over 10 centimetres since 1993, the situation is even worse in the Pacific, where some locations exceed 15 centimetres.

He pointed to emerging science, which suggests that a rise in global temperature by two degrees Celsius over pre-industrial levels could potentially lead to the collapse of both the Greenland and West Antarctica ice sheets, essentially “condemning future generations to unstoppable sea level rise of up to 20 metres - over a period of millennia.”

‘Surging seas are coming for us all’

The world is currently on a trajectory towards a three-degree temperature rise above pre-industrial levels, meaning that sea level rise would happen much more quickly, spelling disaster for Tonga and beyond.

“Surging seas are coming for us all – together with the devastation of fishing, tourism, and the Blue Economy,” the Secretary-General said.

He recalled that roughly a billion people worldwide live in coastal areas, which includes “coastal megacities” such as the Bangladeshi capital, Dhaka; Los Angeles in the United States; Mumbai, India; Lagos, Nigeria, and Shanghai, China. 

Rising seas will increase the frequency of coastal floods and other extreme events, he said, and a 2.5-degree temperature rise could increase the rate from once in 100 years to once in five years by the end of the century.

Without new adaptation and protection measures, the economic damage could amount to trillions of dollars, he added, urging world leaders to step up now.

Reduce global emissions

Mr. Guterres stressed the need to limit global temperature rise to 1.5°C, which means “cutting global emissions 43 percent compared to 2019 levels by 2030, and 60 percent by 2035.”

He called for governments to deliver new national climate action plans, known as Nationally Determined Contributions (NDCs), by 2025, as promised at the UN COP28 climate conference in Dubai last year.

Leaders must also put the world on track to phase out fossil fuels fast and fairly, including ending new coal projects as well as new oil and gas expansion, he continued.  This is in addition to their commitment to triple renewables capacity, double energy efficiency and end deforestation by 2030. 

Support vulnerable countries

The Secretary-General again repeated his long-standing appeal for G20 nations, “the biggest emitters”, to take a leading role in these efforts.

“And the world must massively increase finance and support for vulnerable countries. We need a surge in funds to deal with surging seas,” he said.

Looking ahead to this year’s UN climate conference, he urged countries to “boost innovative financing”.  Richer nations must also deliver on their commitments, which include doubling adaptation finance to at least $40 billion annually by 2025.

Addressing climate justice, he also highlighted the need for “significant contributions” to be made to the new Loss and Damage Fund so as to support the Pacific islands and other vulnerable countries.

The same also applies to initiatives announced during the latest Pacific Islands Forum, which opened in Tonga on Monday August 26 2024.

“Finally, we need to protect every person on Earth with an early warning system by 2027,” he said.  “That means building up countries’ data capacities to improve decision-making on adaptation and coastal planning.” 

Mr. Guterres first announced the Early Warnings for All initiative in March 2022, which calls for ensuring that these lifesaving systems are in place across the planet by the end of 2027.

Ocean ‘treated like a sewer’

“The world has much to learn from you. It must also step up to support you”, he said, adding that their region of “fearless seafarers, expert fishers, and deep ancestral knowledge of the ocean”, and the ocean worldwide is being treated “like a sewer” by humanity at large. 

“Plastic pollution is choking sealife. Greenhouse gases are causing ocean heating, acidification and rising seas. But Pacific islands are showing the way to protect our climate, our planet and our ocean”, he declared.

He pointed to the region’s Declarations on Sea Level Rise, and determination to have a just transition towards a fossil-fuel-free Pacific.

“The young people of the Pacific have taken the climate crisis all the way to the International Court of Justice (ICJ)”, he said.

Big emitters ‘must step up’

While the Pacific region is doing what it can, the G20 most industrialised nations – the biggest emitters of carbon – “must step up and lead, by phasing out the production and consumption of fossil fuels and stopping their expansion immediately”, said the UN Secretary-General.

He stressed that the region urgently needs more financial support, capacities and technology to speed up the transition to clean energy and so countries can invest in adaptation and resilience.

“That is why we have been calling for reform of the international financial architecture, a massive increase in the lending capacity of Multilateral Development Banks, debt relief programmes that work, and an enhanced redistribution of Special Drawing Rights, to benefit developing countries”, the UN chief added.

Save the Pacific, we save the world

He said the decisions on the climate crisis and sustainable development world leaders take in the years ahead, will determine the fate of us all.

“In other words: If we save the Pacific, we save the world. Pacific Island States have a moral and practical imperative to take your leadership to the global stage.

Mr. Guterres stressed that the Summit of the Future in New York next month will be an opportunity to reform and update global institutions, so they can again be fit for purpose.

“I urge Pacific Island States to make your voices heard and heard loudly because the world needs your leadership”, the UN chief concluded.

The Australian Greens have urged Labor to immediately stop backing new coal and gas, following a similar call from the UN Secretary-General overnight.

During the opening day of the Pacific Islands Forum in Tonga, Antonio Guterres called on Australia and other developed nations to immediately ban the expansion of fossil fuel industries to save the world from an “escalating climate crisis”.

Yet despite the science making clear that strong climate action means no new coal and gas, Labor has approved 23 coal and gas projects, with more in the pipeline. 

Leader of the Australian Greens, Adam Bandt MP has stated, post-Mr. Guterres remarks:

“The Prime Minister is a classic type two climate denier.

“Type one is when you deny the science, and type two is when you deny what the science tells you to do.

“Peter Dutton denies what the science says, while Anthony Albanese denies what the science says to do.

“Scientists agree there can be no new coal or gas projects if we’re to avoid climate collapse, yet since coming into power Labor has approved 23 new coal and gas projects to run as late as 2080.

“You can’t put the fire out if you’re pouring petrol on it.”

The following are UN Secretary-General António Guterres’ remarks to the Pacific Islands Forum Opening Ceremony, in Tonga:

It is a great pleasure to address the Pacific Islands Forum. And allow me to express my deep gratitude to the Government and the people of Tonga for their incredible hospitality.

We meet at a turbulent time for our world.  Raging conflicts, an escalating climate crisis, inequalities and injustices everywhere, and the 2030 Agenda is faltering.  But, this region is a beacon of solidarity and strength, environmental stewardship and peace.

The world has much to learn from the Pacific and the world must also step up to support your initiatives.  This is a region of fearless seafarers, expert fishers and deep ancestral knowledge of the ocean.

But, humanity is treating the sea like a sewer.  Plastic pollution is choking sea life.  Greenhouse gases are causing ocean heating, acidification and a dramatic and accelerating rise in sea levels.

Pacific islands are showing the way to protect our climate, our planet and our ocean:  By declaring a climate emergency and pushing for action, and with your Declarations on Sea Level Rise, and aspirations for a just transition to a fossil-fuel-free Pacific.

The young people of the Pacific have taken the climate crisis all the way to the International Court of Justice.  You have also rightly recognised that this is a security crisis — and taken steps to manage those risks together.

I want to express my full support to the 2050 Strategy for the Blue Pacific Continent, and I will do my best to help mobilise international resources for the Pacific Resilience Facility and to engage with all the relevant initiatives the Pacific Island Forum.

The survival plan for our planet is simple:  Establishing a just transition for the phaseout of the fossil fuels that are responsible for 85 per cent of the emissions of greenhouse gases.  All countries must produce national climate plans — nationally determined contributions — by next year, aligning with the 1.5°C upper limit of global heating.

The Group of 20 (G20) — the biggest emitters responsible for 80 per cent of those emissions — must step up and lead, by phasing out the production and consumption of fossil fuels and stopping their expansion immediately.

When Governments sign new oil and gas licenses, they are signing away our future.  The Pacific Island States’ ambition for a fossil-fuel-free Pacific is a blueprint for the G20 and for the world.

But, the region urgently needs substantial finance, capacities and technology to speed up the transition and to invest in adaptation and resilience.

That is why we have been calling for the reform of the international financial architecture, for a massive increase in the lending capacity of multilateral development banks, for debt-relief programmes that work, including for middle-income countries that are in distress, and an enhanced redistribution of special drawing rights, to benefit developing countries and in particular small island developing States.

The decisions world leaders take in the coming years will determine the fate, first of Pacific Islanders — but also of everyone else. In other words: If we save the Pacific, we save the world.

Pacific Island States have a moral and practical imperative to take your leadership and your voice to the global stage.  You demonstrated this leadership once again with the General Assembly’s endorsement of the Multidimensional Vulnerability Index.  We must now make sure that international financial institutions include them in their criteria for operations.

The Summit of the Future in New York next month will be an opportunity to reform and update global institutions, so they are fit for the world of today and tomorrow.

Across the board, the Summit aims to provide developing countries with a greater voice on the global stage, including at the UN Security Council and in international financial institutions.

I urge Pacific Island States to make your voices heard and heard loudly because the world needs your leadership.

Talk isn’t enough: Pacific nations say Australia must end new fossil fuel projects

This week, one of the world’s largest fossil fuel exporters went to a meeting of island states strongly affected by human-induced climate change.

Or, in more conventional language, Australian leaders attended the annual Pacific Islands Forum in Tonga.

Since 1971, this forum has been the top diplomatic meeting for Pacific nations, including Australia and New Zealand. Security was on the agenda this year, against a backdrop of geopolitical manoeuvring and unrest in New Caledonia. But one issue made its presence felt above all else: climate change.

At the forum’s opening, United Nations Secretary-General António Guterres made that clear:

There is an enormous injustice in relation to the Pacific and it’s the reason I am here […] The small islands don’t contribute to climate change but everything that happens because of climate change is multiplied here.

Australia is walking a difficult line at the summit. Pointing to our domestic green energy progress isn’t enough. Our neighbours are focused on Australia’s emergence as the world’s second largest exporter of fossil fuel emissions and steady opening of more gas and coal fields. Even as Australia’s climate and migration pact with Tuvalu came into effect, Tuvalu’s climate change minister, Maina Talia, called for an end to the “immoral and unacceptable” acts of opening new mines, continuing fossil fuel subsidies and exporting fossil fuels.

Australian leaders hope to co-host the world’s top climate talks in 2026 in partnership with Pacific Island nations. While some Pacific leaders are opposed to co-hosting without an Australian pledge to end new goal and gas projects, others see it as a way Australia can show it is truly part of the “Pacific family”.

What happened at the forum?

A big-ticket item at this year’s forum was the Falepili Union, a pact between Australia and Tuvalu signed last year and coming into effect at the forum. Minister for International Development and the Pacific, Pat Conroy, claimed it was the

most significant agreement between Australia and one of its Pacific partners since the agreements for Papua New Guinea’s independence in 1975.

The pact allows 280 Tuvaluans a year to move to Australia, whilst committing Australia to funding climate adaptation work and disaster response efforts on the islands. Significantly, the treaty also states Australia will recognise the statehood of Tuvalu — even if it were to be submerged due to climate change.

In return, Tuvalu and Australia will agree “together” on any arrangements involving Tuvalu’s security or defence. Effectively, this gives Australia the extraordinary ability to block any actions of Tuvalu it feels do not serve its regional interests. This is significant, as China seeks to expand its influence in the Pacific.

At the leaders forum on Thursday, the joint bid to host the 31st United Nations climate conference is expected to be discussed. It’s not guaranteed, as Türkiye has also put in a bid. Pacific leaders have made it clear they will push hard for Australia to go beyond efforts to cut local emissions.

What else might we see?

Analysts have been closely watching how New Zealand leaders approach the forum. While New Zealand has very strong connections to the Pacific and has been actively supporting climate adaptation work in many Pacific nations, the new right wing government is showing signs of backing away from domestic climate efforts.

At the forum, New Zealand’s Deputy Prime Minister and Foreign Minister, Winston Peters, drew attention for downplaying the human role in changing the climate and claiming some Pacific islands are actually growing.

Are island nations united? Not on everything. But on climate, they have learned the power of speaking with a united voice. In recent years, Pacific nations have become the new face of climate diplomacy. At the 2022 Sharm el-Sheikh climate talks in Egypt, Pacific nations were visible and effective in their push to secure better promises of funding to cover loss and damage done by climate change.

Pacific expert George Carter this week described the effective Pacific approach: inviting Australia to be more active as a member of the Pacific family while at the same time pressing us to cut reliance on fossil fuels.

Pacific leaders have consistently said they are willing to take their allegiances elsewhere if high-level rhetoric does not turn into action. In 2019, former Fijian Prime Minister Frank Bainimarama claimed climate reluctance by Australia’s Morrison government would push Pacific nations closer to China.

This is because adapting to sea level rise is expensive, and Pacific nations are small.

Vanuatu, for instance, was the first nation to figure out how much climate adaption would cost them. The answer: A$260 million by 2030 just to respond to loss and damage. To phase out fossil fuels and decarbonise the nation in addition to adaptation projects would cost $1.75 billion — a staggering amount for a small country.

Vanuatu is already the world’s most disaster-prone nation. Rising to the challenge of protecting shorelines and relocating villages comes on top of that.

Fiji has completed six climate-related community relocations to date. According to the government, 42 more need immediate help and another 800 will need assistance soon. Without external funding, the need will soon dwarf what the government can offer.

What’s next?

For the Pacific, climate change is everything. When Guterres talked about moving away from fossil fuels, many observers took that to be a comment aimed at Australia.

It’s unlikely Australia can keep the Pacific onside with bilateral pacts, regional policing initiatives or by pointing to domestic efforts to go green and achieve net-zero later. For the Pacific, the future is now. Climate change is lapping at their shores, and future promises are worth very little.The Conversation

The overshoot myth: you can’t keep burning fossil fuels and expect scientists of the future to get us back to 1.5°C

Record breaking fossil fuel production, all time high greenhouse gas emissions and extreme temperatures. Like the proverbial frog in the heating pan of water, we refuse to respond to the climate and ecological crisis with any sense of urgency. Under such circumstances, claims from some that global warming can still be limited to no more than 1.5°C take on a surreal quality.

For example, at the start of 2023’s international climate negotiations in Dubai, conference president, Sultan Al Jaber, boldly stated that 1.5°C was his goal and that his presidency would be guided by a “deep sense of urgency” to limit global temperatures to 1.5°C. He made such lofty promises while planning a massive increase in oil and gas production as CEO of the Abu Dhabi National Oil Company.

We should not be surprised to see such behaviour from the head of a fossil fuel company. But Al Jaber is not an outlier. Scratch at the surface of almost any net zero pledge or policy that claims to be aligned with the 1.5°C goal of the landmark 2015 Paris agreement and you will reveal the same sort of reasoning: we can avoid dangerous climate change without actually doing what this demands – which is to rapidly reduce greenhouse gas emissions from industry, transport, energy (70% of total) and food systems (30% of total), while ramping up energy efficiency.

A particularly instructive example is Amazon. In 2019 the company established a 2040 net zero target which was then verified by the UN Science Based Targets initiative (SBTi) which has been leading the charge in getting companies to establish climate targets compatible with the Paris agreement. But over the next four years Amazon’s emissions went up by 40%. Given this dismal performance, the SBTi was forced to act and removed Amazon and over 200 companies from its Corporate Net Zero Standard.

This is also not surprising given that net zero and even the Paris agreement have been built around the perceived need to keep burning fossil fuels, at least in the short term. Not do so would threaten economic growth, given that fossil fuels still supply over 80% of total global energy. The trillions of dollars of fossil fuel assets at risk with rapid decarbonisation have also served as powerful brakes on climate action.

Overshoot

The way to understand this doublethink: that we can avoid dangerous climate change while continuing to burn fossil fuels – is that it relies on the concept of overshoot. The promise is that we can overshoot past any amount of warming, with the deployment of planetary-scale carbon dioxide removal dragging temperatures back down by the end of the century.

This not only cripples any attempt to limit warming to 1.5°C, but risks catastrophic levels of climate change as it locks us in to energy and material-intensive solutions which for the most part exist only on paper.

To argue that we can safely overshoot 1.5°C, or any amount of warming, is saying the quiet bit out loud: we simply don’t care about the increasing amount of suffering and deaths that will be caused while the recovery is worked on.

A key element of overshoot is carbon dioxide removal. This is essentially a time machine – we are told we can turn back the clock of decades of delay by sucking carbon dioxide directly out of the atmosphere. We don’t need rapid decarbonisation now, because in the future we will be able to take back those carbon emissions. If or when that doesn’t work, we are led to believe that even more outlandish geoengineering approaches such as spraying sulphurous compounds into the high atmosphere in an attempt to block out sunlight – which amounts to planetary refrigeration – will save us.

The 2015 Paris agreement was an astonishing accomplishment. The establishment of 1.5°C as being the internationally agreed ceiling for warming was a success for those people and nations most exposed to climate change hazards. We know that every fraction of a degree matters. But at the time, believing warming could really be limited to well below 2°C required a leap of faith when it came to nations and companies putting their shoulder to the wheel of decarbonisation. What has happened instead is that the net zero approach of Paris is becoming detached from reality as it is increasingly relying on science fiction levels of speculative technology.

There is arguably an even bigger problem with the Paris agreement. By framing climate change in terms of temperature, it focuses on the symptoms, not the cause. 1.5°C or any amount of warming is the result of humans changing the energy balance of the climate by increasing the amount of carbon dioxide in the atmosphere. This traps more heat. Changes in the global average temperature is the established way of measuring this increase in heat, but no one experiences this average.

Climate change is dangerous because of weather that affects particular places at particular times. Simply put, this extra heat is making weather more unstable. Unfortunately, having temperature targets makes solar geoengineering seem like a sensible approach because it may lower temperatures. But it does this by not reducing, but increasing our interference in the climate system. Trying to block out the sun in response to increasing carbon emissions is like turning on the air conditioning in response to a house fire.

In 2021 we argued that net zero was a dangerous trap. Three years on and we can see the jaws of this trap beginning to close, with climate policy being increasingly framed in terms of overshoot. The resulting impacts on food and water security, poverty, human health, the destruction of biodiversity and ecosystems will produce intolerable suffering.

The situation demands honesty, and a change of course. If this does not materialise then things are likely to deteriorate, potentially rapidly and in ways that may be impossible to control.

Au revoir Paris

The time has come to accept that climate policy has failed, and that the 2015 landmark Paris agreement is dead. We let it die by pretending that we could both continue to burn fossil fuels and avoid dangerous climate change at the same time. Rather than demand the immediate phase out of fossil fuels, the Paris agreement proposed 22nd-century temperature targets which could be met by balancing the sources and sinks of carbon. Within that ambiguity net zero flourished. And yet apart from the COVID economic shock in 2020, emissions have increased every year since 2015, reaching an all time high in 2023.

Despite there being abundant evidence that climate action makes good economic sense (the cost of inaction vastly exceeds the cost of action), no country strengthened their pledges at the last three COPs (the annual UN international meetings) even though it was clear that the world was on course to sail past 2°C, let alone 1.5°C. The Paris agreement should be producing a 50% reduction in greenhouse gas emissions by 2030, but current policies mean that they are on track to be higher than they are today.

Greenhouse gas emissions continue to rise. Catazul/PixabayCC BY

We do not deny that significant progress has been made with renewable technologies. Rates of deployment of wind and solar have increased each year for the past 22 years and carbon emissions are going down in some of the richest nations, including the UK and the US. But this is not happening fast enough. A central element of the Paris agreement is that richer nations need to lead decarbonisation efforts to give lower income nations more time to transition away from fossil fuels. Despite some claims to the contrary, the global energy transition is not in full swing. In fact, it hasn’t actually begun because the transition demands a reduction in fossil fuel use. Instead it continues to increase year-on-year.

And so policymakers are turning to overshoot in an attempt to claim that they have a plan to avoid dangerous climate change. A central plank of this approach is that the climate system in the future will continue to function as it does today. This is a reckless assumption.

2023’s warning signs

At the start of 2023, Berkeley Earth, NASA, the UK Met Office, and Carbon Brief predicted that 2023 would be slightly warmer than the previous year but unlikely to set any records. Twelve months later and all four organisations concluded that 2023 was by some distance the warmest year ever recorded. In fact, between February 2023 and February 2024 the global average temperature warming exceeded the Paris target of 1.5°C.

The extreme weather events of 2023 give us a glimpse of the suffering that further global warming will produce. A 2024 report from the World Economic Forum concluded that by 2050 climate change may have caused over 14 million deaths and US$12.5 trillion in loss and damages.

Currently we cannot fully explain why global temperatures have been so high for the past 18 months. Changes in dust, soot and other aerosols are important, and there are natural processes such as El Niño that will be having an effect.

But it appears that there is still something missing in our current understanding of how the climate is responding to human impacts. This includes changes in the Earth’s vital natural carbon cycle.

Around half of all the carbon dioxide humans have put into the atmosphere over the whole of human history has gone into “carbon sinks” on land and the oceans. We get this carbon removal “for free”, and without it, warming would be much higher. Carbon dioxide from the air dissolves in the oceans (making them more acidic which threatens marine ecosystems). At the same time, increasing carbon dioxide promotes the growth of plants and trees which locks up carbon in their leaves, roots, trunks.

All climate policies and scenarios assume that these natural carbon sinks will continue to remove tens of billions of tons of carbon from the atmosphere each year. There is evidence that land-based carbon sinks, such as forests, removed significantly less carbon in 2023. If natural sinks begin to fail – something they may well do in a warmer world – then the task of lowering global temperatures becomes even harder. The only credible way of limiting warming to any amount, is to stop putting greenhouse gasses into the atmosphere in the first place.

Science fiction solutions

It’s clear that the commitments countries have made to date as part of the Paris agreement will not keep humanity safe while carbon emissions and temperatures continue to break records. Indeed, proposing to spend trillions of dollars over this century to suck carbon dioxide out of the air, or the myriad other ways to hack the climate is an acknowledgement that the world’s largest polluters are not going to curb the burning of fossil fuels.

Over the following years we are going to see climate impacts increase. Lethal heatwaves are going to become more common. Storms and floods are going to become increasingly destructive. More people are going to be displaced from their homes. National and regional harvests will fail. Vast sums of money will need to be spent on efforts to adapt to climate change, and perhaps even more compensating those who are most affected. We are expected to believe that while all this and more unfolds, new technologies that will directly modify the Earth’s atmosphere and energy balance will be successfully deployed.

What’s more, some of these technologies may need to operate for three hundred years in order for the consequences of overshoot to be avoided. Rather than quickly slow down carbon polluting activities and increasing the chances that the Earth system will recover, we are instead going all in on net zero and overshoot in an increasingly desperate hope that untested science fiction solutions will save us from climate breakdown.

We can see the cliff edge rapidly approaching. Rather than slam on the brakes, some people are instead pushing their foot down harder on the accelerator. Their justification for this insanity is that we need to go faster in order to be able to make the jump and land safely on the other side.

We believe that many who advocate for carbon dioxide removal and geoengineering do so in good faith. But they include proposals to refreeze the Arctic by pumping up sea water onto ice sheets to form new layers of ice and snow. These are interesting ideas to research, but there is very little evidence this will have any effect on the Arctic let alone global climate. These are the sorts of knots that people tie themselves up in when they acknowledge the failure of climate policy, but refuse to challenge the fundamental forces behind such failure. They are unwittingly slowing down the only effective action of rapidly phasing out fossil fuels.

That’s because proposals to remove carbon dioxide from the air or geoengineer the climate promise a recovery from overshoot, a recovery that will be delivered by innovation, driven by growth. That this growth is powered by the same fossil fuels that are causing the problem in the first place doesn’t feature in their analysis.

The bottom line here is that the climate system is utterly indifferent to our pledges and promises. It doesn’t care about economic growth. And if we carry on burning fossil fuels then it will not stop changing until the energy balance is restored. By which time millions of people could be dead, with many more facing intolerable suffering.

Major climate tipping points

Even if we assume that carbon removal and even geoengineering technologies can be deployed in time, there is a very large problem with the plan to overshoot 1.5°C and then lower temperatures later: tipping points.

The science of tipping points is rapidly advancing. Late last year one of us (James Dyke) along with over 200 academics from around the world was involved in the production of the Global Tipping Points Report. This was a review of the latest science about where tipping points in the climate system may be, as well as exploring how social systems can undertake rapid change (in the direction that we want) thereby producing positive tipping points. Within the report’s 350 pages is abundant evidence that the overshoot approach is an extraordinarily dangerous gamble with the future of humanity. Some tipping points have the potential to cause global havoc.

The melt of permafrost could release billions of tons of greenhouse gasses into the atmosphere and supercharge human-caused climate change. Fortunately, this seems unlikely under the current warming. Unfortunately, the chance that ocean currents in the North Atlantic could collapse may be much higher than previously thought. If that were to materialise, weather systems across the world, but in particular in Europe and North America, would be thrown into chaos. Beyond 1.5°C, warm water coral reefs are heading towards annihilation. The latest science concludes that by 2°C global reefs would be reduced by 99%. The devastating bleaching event unfolding across the Great Barrier Reef follows multiple mass mortality events. To say we are witnessing one of the world’s greatest biological wonders die is insufficient. We are knowingly killing it.

We may have even already passed some major climate tipping points. The Earth has two great ice sheets, Antarctica, and Greenland. Both are disappearing as a consequence of climate change. Between 2016 and 2020, the Greenland ice sheet lost on average 372 billion tons of ice a year. The current best assessment of when a tipping point could be reached for the Greenland ice sheet is around 1.5°C.

This does not mean that the Greenland ice sheet will suddenly collapse if warming exceeds that level. There is so much ice (some 2,800 trillion tons) that it would take centuries for all of it to melt over which time sea levels would rise seven metres. If global temperatures could be brought back down after a tipping point, then maybe the ice sheet could be stabilised. We just cannot say with any certainty that such a recovery would be possible. While we struggle with the science, 30 million tons of ice is melting across Greenland every hour on average.

The take home message from research on these and other tipping points is that further warming accelerates us towards catastrophe. Important science, but is anyone listening?

It’s five minutes to midnight…again

We know we must urgently act on climate change because we are repeatedly told that time is running out. In 2015, Professor Jeffrey Sachs, the UN special adviser and director of The Earth Institute, declared:

The time has finally arrived – we’ve been talking about these six months for many years but we’re now here. This is certainly our generation’s best chance to get on track.

In 2019 (then) Prince Charles gave a speech in which he said: “I am firmly of the view that the next 18 months will decide our ability to keep climate change to survivable levels and to restore nature to the equilibrium we need for our survival.”

“We have six months to save the planet,” exhorted International Energy Agency head Fatih Birol – one year later in 2020. In April 2024, Simon Stiell, executive secretary of the United Nations Framework Convention on Climate Change said the next two years are “essential in saving our planet”.

Either the climate crisis has a very fortunate feature that allows the countdown to catastrophe to be continually reset, or we are deluding ourselves with endless declarations that time has not quite run out. If you can repeatedly hit snooze on your alarm clock and roll over back to sleep, then your alarm clock is not working.

Or there is another possibility. Stressing that we have very little time to act is intended to focus attention on climate negotiations. It’s part of a wider attempt to not just wake people up to the impending crisis, but generate effective action. This is sometimes used to explain how the 1.5°C threshold of warming came to be agreed. Rather than a specific target, it should be understood as a stretch goal. We may very well fail, but in reaching for it we move much faster than we would have done with a higher target, such as 2°C. For example, consider this statement made in 2018:

Stretching the goal to 1.5 degrees celsius isn’t simply about speeding up. Rather, something else must happen and society needs to find another lever to pull on a global scale.

What could this lever be? New thinking about economics that goes beyond GDP? Serious consideration of how rich industrialised nations could financially and materially help poorer nations to leapfrog fossil fuel infrastructure? Participatory democracy approaches that could help birth the radical new politics needed for the restructuring of our fossil fuel powered societies? None of these.

The lever in question is Carbon Capture and Storage (CCS) because the above quote comes from an article written by Shell in 2018. In this advertorial Shell argues that we will need fossil fuels for many decades to come. CCS allows the promise that we can continue to burn fossil fuels and avoid carbon dioxide pollution by trapping the gas before it leaves the chimney. Back in 2018, Shell was promoting its carbon removal and offsets heavy Sky Scenario, an approach described as “a dangerous fantasy” by leading climate change academics as it assumed massive carbon emissions could be offset by tree planting.

Since then Shell has further funded carbon removal research within UK universities presumably in efforts to burnish its arguments that it must be able to continue to extract vast amounts of oil and gas.

Shell is far from alone in waving carbon capture magic wands. Exxon is making great claims for CCS as a way to produce net zero hydrogen from fossil gas – claims that have been subject to pointed criticism from academics with recent reporting exposing industry wide greenwashing around CCS.

But the rot goes much deeper. All climate policy scenarios that propose to limit warming to near 1.5°C rely on the largely unproven technologies of CCS and BECCS. BECCS sounds like a good idea in theory. Rather than burn coal in a power station, burn biomass such as wood chips. This would initially be a carbon neutral way of generating electricity if you grew as many trees as you cut down and burnt. If you then add scrubbers to the power station chimneys to capture the carbon dioxide, and then bury that carbon deep underground, then you would be able to generate power at the same time as reducing concentrations of carbon dioxide in the atmosphere.

Unfortunately, there is now clear evidence that in practice, large-scale BECCS would have very adverse effects on biodiversity, and food and water security given the large amounts of land that would be given over to fast growing monoculture tree plantations. The burning of biomass may even be increasing carbon dioxide emissions. Drax, the UK’s largest biomass power station now produces four times as much carbon dioxide as the UK’s largest coal-fired power station.

Five minutes to midnight messages may be motivated to try to galvanise action, to stress the urgency of the situation and that we still (just) have time. But time for what? Climate policy only ever offers gradual change, certainly nothing that would threaten economic growth, or the redistribution of wealth and resources.

Despite the mounting evidence that globalised, industrialised capitalism is propelling humanity towards disaster, five minutes to midnight does not allow time and space to seriously consider alternatives. Instead, the solutions on offer are techno fixes that prop up the status quo and insists that fossil fuel companies such as Shell must be part of the solution.

That is not to say there are no good faith arguments for 1.5°C. But being well motivated does not alter reality. And the reality is that warming will soon pass 1.5°C, and that the Paris agreement has failed. In the light of that, repeatedly asking people to not give up hope, that we can avoid a now unavoidable outcome risks becoming counterproductive. Because if you insist on the impossible (burning fossil fuels and avoiding dangerous climate change), then you must invoke miracles. And there is an entire fossil fuel industry quite desperate to sell such miracles in the form of CCS.

Four suggestions

Humanity has enough problems right now, what we need are solutions. This is the response we sometimes get when we argue that there are fundamental problems with the net zero concept and the Paris agreement. It can be summed up with the simple question: so what’s your suggestion? Below we offer four.

1. Leave fossil fuels in the ground

The unavoidable reality is that we need to rapidly stop burning fossil fuels. The only way we can be sure of that is by leaving them in the ground. We have to stop exploring for new fossil fuel reserves and the exploitation of existing ones. That could be done by stopping fossil fuel financing.

At the same time we must transform the food system, especially the livestock sector, given that it is responsible for nearly two thirds of agricultural emissions. Start there and then work out how best the goods and services of economies can be distributed. Let’s have arguments about that based on reality not wishful thinking.

2. Ditch net zero crystal ball gazing targets

The entire framing of mid and end-century net zero targets should be binned. We are already in the danger zone. The situation demands immediate action, not promises of balancing carbon budgets decades into the future. The SBTi should focus on near-term emissions reductions. By 2030, global emissions need to be half of what they are today for any chance of limiting warming to no more than 2°C.

It is the responsibility of those who hold most power – politicians and business leaders – to act now. To that end we must demand twin targets – all net zero plans should include a separate target for actual reductions in greenhouse gas emissions. We must stop hiding inaction behind promises of future removals. It’s our children and future generations that will need to pay back the overshoot debt.

3. Base policy on credible science and engineering

All climate policies must be based on what can be done in the real world now, or in the very near future. If it is established that a credible amount of carbon can be removed by a proposed approach – which includes capture and its safe permanent storage – then and only then can this be included in net zero plans. The same applies to solar geoengineering.

Speculative technologies must be removed from all policies, pledges and scenarios until we are sure of how they will work, how they will be monitored, reported and validated, and what they will do to not just the climate but the Earth system as a whole. This would probably require a very large increase in research. As academics we like doing research. But academics need to be wary that concluding “needs more research” is not interpreted as “with a bit more funding this could work”.

4. Get real

Finally, around the world there are thousands of groups, projects, initiatives, and collectives that are working towards climate justice. But while there is a Climate Majority Project, and a Climate Reality Project, there is no Climate Honesty Project (although People Get Real does come close). In 2018 Extinction Rebellion was formed and demanded that governments tell the truth about the climate crisis and act accordingly. We can now see that when politicians were making their net zero promises they were also crossing their fingers behind their backs.

We need to acknowledge that net zero and now overshoot are becoming used to argue that nothing fundamental needs to change in our energy intensive societies. We must be honest about our current situation, and where we are heading. Difficult truths need to be told. This includes highlighting the vast inequalities of wealth, carbon emissions, and vulnerability to climate change.

The time for action is now

We rightly blame politicians for failing to act. But in some respects we get the politicians we deserve. Most people, even those that care about climate change, continue to demand cheap energy and food, and a constant supply of consumer products. Reducing demand by just making things more expensive risks plunging people into food and energy poverty and so policies to reduce emissions from consumption need to go beyond market-based approaches. The cost of living crisis is not separate from the climate and ecological crisis. They demand that we radically rethink how our economies and societies function, and whose interests they serve.

To return to the boiling frog predicament at the start, it’s high time for us to jump out of the pot. You have to wonder why we did not start decades ago. It’s here that the analogy offers valuable insights into net zero and the Paris agreement. Because the boiling frog story as typically told misses out a crucial fact. Regular frogs are not stupid. While they will happily sit in slowly warming water, they will attempt to escape once it becomes uncomfortable. The parable as told today is based on experiments at the end of the 19th century that involved frogs that had been “pithed” – a metal rod had been inserted into their skulls that destroyed their higher brain functioning. These radically lobotomised frogs would indeed float inert in water that was cooking them alive.

Promises of net zero and recovery from overshoot are keeping us from struggling to safety. They assure us nothing too drastic needs to happen just yet. Be patient, relax. Meanwhile the planet burns and we see any sort of sustainable future go up in smoke.

Owning up to the failures of climate change policy doesn’t mean giving up. It means accepting the consequences of getting things wrong, and not making the same mistakes. We must plan routes to safe and just futures from where we are, rather where we would wish to be. The time has come to leap.
