Warm-water coral reefs have crossed a tipping point due to global heating and are dying at an accelerated rate due to repeated mass bleaching events, impacting hundreds of millions of people who rely on them for fishing, tourism and protection from rising seas and storm surges, according to new research.

Global average temperatures are about 1.3-1.4C above pre-industrial times, which is higher than coral reefs can withstand. Their thermal tipping point is estimated to be 1.2C of warming.

If the trend is not reversed, coral reefs around the world will be lost, warned the second Global Tipping Points report, released on Monday and produced by more than 160 scientists in 23 countries, led by the Global Systems Institute at the UK’s University of Exeter.

Of the seven tipping points monitored by the researchers, this is the first to be shown as already passed. “We’ve actually already lost about half our warm-water coral reef cover, and we can expect accelerated change in the next few decades as well,” said Mike Barrett, chief scientific advisor at WWF-UK.

The report also said parts of the West Antarctic and Greenland ice sheets are losing ice at an accelerating speed, coming close to collapse. Greenland’s ice sheet is losing 266 billion tonnes of ice mass per year. If that meltwater flows into the North Atlantic and destabilises its subpolar gyre (large rotating current), it could produce a “Little Ice Age” in Europe, with worsening heatwaves in the summer but freezing months in the winter.

The report also said the Amazon rainforest is at greater risk than previously thought. Steven Smith from the Global Systems Institute told a webinar on the report that “the combined effects of climate change and deforestation put this [the rainforest] under threat between 1.5 to 2 degrees of warming.”

    Overshooting the 1.5C warming limit governments promised to try to keep to under the Paris Agreement now looks “pretty inevitable”, and could happen around 2030, according to the report.

    The researchers said they are working with Brazil to ensure that tipping points are discussed at the COP30 climate summit it will host in November, highlighting actions that need to be taken fast.

    Those include phasing out fossil fuels, increasing support for clean technologies and infrastructure, and switching to more sustainable food systems.

    “Governance systems, national policies, rules, multinational agreements – including the Paris Agreement – were not designed with tipping points in mind,” said Manjana Milkoreit from the University of Oslo. “They’re made for linear or gradual changes, not the abrupt, irreversible and interconnected shifts in the Earth systems that we’re now facing.”

    The consequences of a warming ocean

    Corals not only provide livelihoods, food security and protection from tropical storms for over half a billion people – they also deliver $2.7 trillion annually in global economic benefits, the scientists said.

    Melanie McField, founder and director of the Healthy Reefs for Healthy People Initiative (HRI), explained that the tipping point is not necessarily irreversible, as not all corals are affected at the same time – and ocean protection efforts in general could save them from becoming victims of overfishing and pollution.

    In recent weeks, new reports have confirmed the effects of heat on the oceans and marine life. The EU Copernicus Ocean State Report showed that almost a quarter of the global ocean surface experienced at least one severe to extreme marine heatwave event in 2023 – a trend that has accelerated since 2005.

      And last month, the annual planetary boundaries report from the Potsdam Institute for Climate Impact Research (PIK) said the planetary limit for ocean acidification had been surpassed for the first time, weakening the oceans’ ability to act as Earth’s stabiliser.

      Oceans turn more acidic by absorbing CO2 from the atmosphere, a process that threatens marine life, with 1,677 species at risk of extinction, PIK said. The Copernicus report indicates a 16.5% increase in ocean acidity since 1985.

      Meanwhile, ocean heatwaves not only have become more frequent but have also caused the planet’s seas to reach new record temperatures. The warmest the ocean has been since satellite data started to be collected was in spring 2024, when the global average hit 21C. More than 90% of the excess heat trapped in the Earth’s system due to human-caused global warming has been absorbed by the oceans, according to the US National Oceanic and Atmospheric Administration. 

      Marta Marcos, an associate professor at the University of the Balearic Islands and one of the Copernicus’ study authors, told Climate Home News another key issue is the acceleration in sea level rise, which began speeding up in the 1960s-70s and is now above 4 millimetres per year. “Sea level not only continues to rise, but is rising at an ever faster rate,” she said.

      Rate of global sea level rise: 1999-2006 (31.4 mm/decade), 2007-2015 (39.3 mm/decade), and 2016-2024 (40.8 mm/decade). Source: EU Copernicus Ocean State Report (OSR)

      While sea level rise is a global trend, the major risk is in densely populated cities near the sea. For example, in Europe around 200 million people live near coastlines and higher baseline sea levels increase the threat to their homes and infrastructure from extreme weather. “When a storm comes, with its surge and waves, it has a much greater destructive potential,” explained Marcos.

      Blue NDCs bring oceans into climate plans

      Marcos believes there is growing government interest in protecting the oceans. In September, the High Seas Treaty, which lays the ground for the creation of marine protected areas (MPAs) in international waters, reached the 60 government ratifications needed for it to take effect.

      And during New York Climate Week in September, Chile and the UK committed to include ocean-based solutions in their national climate plans (known as NDCs). Eleven countries have now joined the “Blue NDC” project which encourages governments – depending on their circumstances – to manage marine ecosystems, phase out offshore oil and gas production, expand clean ocean energy, cut emissions and support sustainable fisheries.

      Others with Blue NDCs are Brazil, France, Australia, Fiji, Kenya, Mexico, Palau, Madagascar and the Republic of Seychelles.

      Such ocean-based solutions can provide 35% of the emissions reductions the world needs by 2035, a study by the High Level Panel for a Sustainable Ocean Economy shows. 

      Mary Creagh, the UK’s minister for nature, said oceans are central to her country’s NDC – but work is still being finalised on how to count emissions reductions from seagrass and seaweed management and coastal restoration. “We’re working on the science, which we’re happy to share globally once it is complete,” she added.

      One key challenge is getting the world’s largest fish-producing countries to sign up to tackle ocean issues in their climate plans, particularly Asian heavyweights such as China, Indonesia, India and Vietnam.

      Blue NDC member and COP30 host Brazil, meanwhile, recently announced its largest oil and gas discovery in 25 years in the Santos Basin, 400 kilometres off its coast.

      Nonetheless, Marcos said such initiatives are important, adding that any effective action “has to be global, coordinated, and based on data and science”.

      Marinez Scherer, a marine biologist and coastal management expert who is the COP30 Special Envoy for Oceans, said the upcoming operationalisation of the High Seas Treaty is a step forward on the path to the climate summit, which she said would discuss a plan to speed up implementation of ocean solutions.

      Scherer said COP30 will present measures that are currently working in Brazil and show the world what’s needed to “plan and manage the ocean in a very healthy and sustainable way”.

      What is the Pacific Islands Forum (PIF)?

      The Pacific Islands Forum, or ‘PIF’, is our region’s most important political organisation. It is where countries of the Pacific — including Australia and New Zealand — come together to collaborate on shared challenges and to set collective goals.

      The PIF Leaders Meeting is an annual weeklong event that includes a dedicated meeting of the Pacific’s small island developing states (PSIDS), many special side events organised by Pacific civil society, the leaders’ meeting itself, and more. At the end of the week, leaders issue a Forum Communiqué, capturing what they have agreed on, their shared priorities and the actions they will take together.

      This year’s meeting is being held in the beautiful northern Pacific nation of Palau, the same place our Pacific team gathered back in January to plan for the year.

      What’s at stake this year?

      Climate change has dominated the PIF for decades. Pacific leaders have been crystal clear it is their number one priority, and the annual gathering is the moment they can exert maximum pressure on Australia over its fossil fuel record.

      The voyage to COP31

      This year’s meeting comes less than three months before COP31, where Australia will take on the role of President of Negotiations — a role it has committed to undertaking in partnership with the Pacific — and less than a month before the ‘Pacific Pre-COP’, to be held in Fiji and Tuvalu.

      Following a fraught round of mid-year negotiations in Bonn, PIF leaders will need to set out a clear vision and priorities for COP31. These include accelerating a just global transition away from fossil fuels, defending science as the foundation of international climate cooperation, and increasing the availability and accessibility of finance for renewable energy and climate adaptation.

      Accountability for Australian fossil fuel exports

      Since the last PIF Leaders Meeting, Australia has signed the Belém Declaration on the Transition Away from Fossil Fuels. The declaration reaffirmed the legally binding commitment to help limit global warming to 1.5°C and recognised that this is incompatible with new fossil fuel production. Yet, Australia has continued to approve new coal and gas projects, including at least five since the last PIF Leaders Meeting.

      From firefighting to future-proofing: Preventing wildfires must be the priority

      Published

      on

      Gill Einhorn is head of the Forest Future Alliance and Natalie Çilem is community lead of the Global Wildfire Leadership Network.

      Wildfires have devastated communities across the world this summer, claiming lives, displacing thousands of people and leaving billions in economic damage in their wake. In Europe alone, wildfires have already caused an estimated €19 billion in losses this year.

      They are an economic, financial and public health challenge that is growing faster than many governments and markets are prepared for – and exposing the real costs of poor land management.

      A system built for recovery, not resilience

      Far more money is currently spent responding to the disastrous effects of wildfires than preventing them in the first place. The United Nations Environment Programme estimates that more than half of wildfire-related spending goes towards response, while planning receives only around 0.2 percent. This problem is not limited to wildfires; over 95 percent of disaster aid between 2005 and 2017 was allocated to response, and less than 4 percent was directed towards prevention or preparedness.

      Forests are critical, but without investment in how land is managed and protected, their value is neither stable nor guaranteed. Protecting forests requires investing not only in conservation, but in the conditions that keep forests standing.

        Each dollar invested in wildfire-resistant construction could save around $210 in avoided future economic losses, according to a report by the World Economic Forum and Forest Future Alliance. Despite this evidence that prevention can significantly reduce future costs, wildfire resilience remains chronically underfunded.

        This spending discrepancy is creating significant challenges for insurers, asset owners and financial institutions. Global insured losses from natural catastrophes reached $107 billion in 2025, with wildfires, floods and storms accounting for 92 percent of claims.

        In this context, insurers are reassessing where and how they are willing to underwrite risk. Around 56 percent of global wildfire losses between 2000 and 2023 were uninsured. In some high-risk areas, insurers are scaling back coverage altogether, leaving homeowners, businesses and governments to shoulder a growing share of the costs – making it increasingly difficult to break even.

        Proven solutions are already paying off

        In many regions, wildfires are driven not by natural causes but by the deliberate clearing of land for agriculture. Degraded landscapes are becoming drier, more flammable and increasingly vulnerable to catastrophic loss, creating a vicious cycle of deforestation, economic damage and rising emissions.

        The answer is not simply stronger firefighting capacity. Governments, investors and businesses must work together to shift capital upstream into prevention, resilience and long-term landscape stewardship of healthy forests. That means planting appropriately, investing in heat-resistant species, exploring approaches that minimise fire footprints through active management, and exploring the AI and technology solutions that are burgeoning.

        Solutions to this already exist and are proven to have an impact. Following devastating wildfires year-on-year, Portugal shifted its approach to wildfire management, increasing prevention spending within its national rural fire management system from around 20 percent in 2017 to approximately 60 percent in 2022. While many countries remain locked in a reactive cycle of disaster response, public policy can shift investment upstream and make resilience a priority before fires occur.

        Indigenous communities have long used proactive land stewardship to reduce wildfire risk while supporting healthy and productive landscapes. For example, the Cheslatta Carrier Nation in British Columbia traditionally managed fuels through cultural fire practices but now implements mechanised fuel removal methods under commercial agreements. By combining Indigenous stewardship with sustainable forest management, Cheslatta is generating community benefits while also boosting wildfire prevention.

        Resilience can also be strengthened through finance and technology. FireSat, a partnership led by Earth Fire Alliance with Google.org, the Gordon and Betty Moore Foundation and Muon, is a satellite constellation designed for rapid wildfire detection. Scanning every 20 minutes, it can detect fires 400 times smaller than current systems and track them through smoke and darkness in almost real time. In California alone, FireSat could prevent up to 350,000 acres from burning each year. It has recently received significant new investments allowing it to expand towards a constellation of more than 50 satellites that will monitor every point on Earth every 20 minutes or less.

        In Brazil’s Pantanal, the Embrace the Forest initiative uses AI-powered detection towers across 2.5 million hectares to support earlier intervention and faster response. During the severe 2024 fire season, the initiative contributed to a 40 percent reduction in burned area compared to 2020.

        These examples illustrate what is possible when resilience is treated as an investment priority rather than a recovery cost. But we must ensure funding for these measures is scaled before disaster strikes. Initiatives like the Global Wildfire Leadership Network (GWLN) are key, bringing together corporate decision-makers, investors, insurers, governments and Indigenous leaders to direct investment towards prevention and align finance, technology and stewardship to protect nature, safeguard communities and strengthen future economic stability. With a goal of doing more together than the sum of our parts, the network focuses on Forest Future Alliance GWLN Solutions Labs – where partners sign up with the intent to collaborate.

        Rewarding prevention

        Financial incentives must be created that reward prevention. This can be done by scaling public-private partnerships, supporting long-term landscape stewardship, investing in community capacity including Indigenous wisdom and technology. Ultimately, our terrestrial natural reserves are critical infrastructure that support resilient economies and thriving communities.

        One in three people are dependent on forest services, goods and economic opportunities for survival, so it’s in all our interests to protect what we have. Forests support cooling, water and food security – and are a very cost-effective way of removing carbon dioxide from the atmosphere, where done appropriately.

        UN chief warns climate crisis “in overdrive” as El Niño threatens to fuel the fire

        No sector can solve this challenge alone. The benefits of wildfire resilience are shared across communities, governments, insurers, investors, utilities and businesses. A single intervention can protect homes and livelihoods, reduce insurance claims, secure water supplies and lower future public costs. Because the benefits are shared, the solutions must be too. Coalitions of actors can take proven approaches further than any one individual or organisation could alone.

        As wildfires continue to burn at an unprecedented scale, the opportunity now is to roll out solutions, shift investment upstream and build a future where resilience, rather than recovery, becomes the foundation of thriving economies.

        Guest post: Why tough methane cuts are crucial for keeping warming ‘well-below’ 2C

        Published

        on

        Methane is a powerful greenhouse gas and the second-largest contributor to global warming after carbon dioxide (CO2).

        Methane traps heat in the atmosphere more efficiently than CO2, but has a significantly shorter lifespan, fading after just a few decades.

        Therefore, reducing emissions of methane – a gas primarily produced by agriculture, fossil fuels and waste management – is a powerful option for limiting global warming in the near-term.

        Yet climate strategies and models often only focus on CO2, or combine all greenhouse gases into one metric known as “CO2 equivalent”.

        The latter approach makes reducing methane emissions dependent on modelling choices and assumptions about the “equivalence” of methane and CO2.

        It hides the opportunities and challenges linked to methane’s high warming and short lifetime.

        In a new study, published in Communications Earth & Environment, we offer a different perspective that “decouples” CO2 and methane reduction and takes global warming limits as a starting point for determining the required level of methane cuts.

        We show that, even under the most ambitious existing national net-zero targets, an absence of methane reduction leads to peak warming that exceeds 1.85C above pre-industrial levels.

        The study highlights that, to limit peak warming to well-below 2C, net-zero CO2 targets must be complemented by stringent methane emissions cuts.

        CO2 equivalent

        How much methane corresponds to one tonne of CO2?

        The question is as difficult to answer as: ‘how much spaghetti equals a chicken?’ You could compare the two meals according to their calories, protein content or cost. Each metric can be convenient, but is only valid for that specific comparison – no amount of spaghetti is the same as a chicken.

        The same is true for the conversion of emissions of methane and other gases to CO2-equivalent emissions. It can be convenient, as it allows different gases to be compared or combined into a single number. This is why the metric is used in climate targets or evaluating the effectiveness of different mitigation options.

        But, because methane and CO2 have different atmospheric lifetimes and warming properties, any conversion is only valid for a chosen time horizon and a chosen baseline.

        Depending on the assumptions baked into calculations, methane mitigation can either appear as an immediate priority or framed as almost unnecessary.

        There are a number of metrics that scientists use to convert greenhouse gases – whether methane, hydrofluorocarbons or nitrous oxide – into CO2-equivalent emissions:

        • “GWP20” measures how much heat a greenhouse gas traps in the atmosphere over a 20-year period, relative to CO2. It emphasises urgent methane mitigation but has been criticised for its implicit discounting of future damages.
        • “GWP100” looks at a 100-year timeline. It gives more weight to long-term warming and is used in “integrated assessment models” (IAMs) used by scientists, national emission reporting to the UN and by the GHG Protocol used by companies.
        • GWP*” considers the rate of emissions, rather than warming over a fixed time horizon. Under GWP*, very limited methane reductions bring CO2-equivalent emissions to zero, meaning remaining methane emissions can be designated as causing “no additional warming”. (This interpretation remains controversial as it assumes the continuation of historical levels of warming.)

        IAMs are the tools used to generate future emissions scenarios. Because they combine CO2 and methane emissions, the impact of methane emission cuts alone is difficult to isolate in existing emission scenarios.

        IAM-generated scenarios also assume mitigation decisions driven by costs. Combinations of CO2 and methane emission pathways that are not purely cost-effective are, therefore, not represented, even though climate policy is messy and emission pathways are rarely cost-effective in the real world.

        Only a few countries – including Japan, Mexico and South Korea – specify methane mitigation targets.

        A different approach

        In our study, we separate CO2 and methane emissions and treat them as independent.

        Instead of choosing a conversion method, we suggest that states and organisations set a limit on peak global warming first, then, based on their existing net-zero targets, determine the minimum compatible methane reduction target.

        Companies and countries around the world have set net-zero targets focused on CO2, as well as those that include all greenhouse gases. As a result, our research looks at the necessary methane reductions for both types of goal. We consider scenarios where companies or countries deliver linear – in other words, steady – emissions reductions to reach net-zero.

        Using a simple climate model, we systematically combined methane and CO2 (or greenhouse gas) mitigation pathways starting in 2025 and calculated peak warming.

        The figure below shows how peak warming depends on both the year of reaching net-zero CO2 and the level of methane cuts.

        Peak global warming relative to 1850-1900 reached until 2100 (50% likelihood), for combinations of the year of global net-zero CO2 emissions (x-axis) and the change in global methane (CH4) emissions between 2020 and that year (y-axis), assuming linear trajectories. Black lines are contours of equal peak warming. The three bars on the right show independent estimates of where CH4 emissions could or would land on the same vertical scale: CH4 mitigation available at no net cost (IEA, red), the 2030 mitigation potential (Global methane status report, orange), and the current legislation scenario for 2050 (Global methane status report, purple). Adapted from Weber et al. (2026).

        The blue arrows in the figure show that to limit warming to 1.7C under a 2050 net-zero CO2 scenario, methane emissions would need to fall by at least 69% by 2050, relative to 2020.

        Our research also finds that, if an organisation or country’s 2050 net zero-target covers all greenhouse gases, its methane emissions would need to fall by 63% instead.

        However, under current policies, methane emissions are expected to increase by around 20% by 2050, relative to 2020. We find that this pathway would result in peak warming above 2C by 2050 – even if global CO2 emissions were to reach net-zero by that date (see purple bar on the right-hand side of the figure above).

        The figure also shows how, if methane emissions remained at 2020 levels and net-zero CO2 was delivered by 2040 or later, warming would exceed 1.85C. This level of warming is above what has been argued as consistent with the Paris Agreement’s “well-below” 2C limit.

        Conversely, cutting methane emissions by around one-third – in line with the Global Methane Pledge target for 2030 – could reduce peak warming by 0.15C, of which 0.05C could be delivered by interventions that come at no net cost. These are shown by the orange and red bars, respectively, on the figure above.

        The table below highlights the minimum compatible methane cuts for three different peak warming levels and net-zero CO2 or greenhouse-gas emission targets.

        Peak warming Year of net-zero CO2 emissions Year of net-zero greenhouse-gas emissions
        2050 2060 2100 2050 2060 2100
        1.7C -69% -63%
        1.8C -32% -56% -11% -47%
        2C +8% -8% -83% >50% +33% -78%

        Minimum methane emission reductions between 2020 and the year of net-zero emissions, consistent with peak warming of 1.7C, 1.8C, and 2.0C at 50% likelihood, assuming linear emission trajectories. For some net-zero targets and peak warming levels, there are no compatible methane mitigation targets (indicated by “–”).

        Remaining carbon budget

        The global carbon budget refers to the amount of cumulative CO2 emissions allowable while still meeting a particular global warming threshold.

        The 2021 climate science report from the Intergovernmental Panel on Climate Change (IPCC) and a 2023 Nature study estimated that, by 2025, the remaining carbon budget for holding warming to 2C would be around 1,000-1,150bn tonnes of CO2 (GtCO2).

        We find that these estimates are founded on the assumption of methane reductions of 27-35% by 2050, relative to a 2020 baseline. (A 2024 Communications Earth & Environment study reached similar conclusions.)

        Under the GWP* metric, where methane emissions are only cut to maintain “no additional warming”, the remaining carbon budget would be constrained. The best estimate of a 2C budget shrinks by around 30% to approximately 750GtCO2.

        Finally, if methane emissions are not cut at all in the future, our findings suggest that the remaining carbon budget for 1.7C of global warming has, in effect, already been exhausted.

        Our analysis shows how peak warming depends on both CO2 and methane reduction – and how methane-specific targets can help refine existing net-zero targets.

        Crucially, we show that complementing net-zero CO2 targets with stringent methane cuts is necessary to limit peak warming to well-below 2C.
