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”.

      To phase out fossil fuels, developing countries need exit route from “debt trap”

      Published

      on

      High levels of national debt in parts of the Global South could hinder efforts to move away from fossil fuels, a new report warns, as more than 50 countries gather this week in Colombia for the First Conference on Transitioning Away from Fossil Fuels.

      The report, published by the Fossil Fuel Treaty Initiative in the lead-up to the flagship conference, argues that the current debt architecture is trapping developing countries in a “feedback loop” in which fossil fuel revenues are needed to service debt, while fossil fuel expansion locks countries into borrowing even more.

      The cycle, according to the report, leaves very little fiscal space for highly indebted countries to end their reliance on coal, oil and gas revenues, even when their leaders want to phase out fossil fuels. This is the case for some first-mover countries such as Colombia, which is hosting the conference in Santa Marta.

      Amiera Sawas, one of the report’s authors and head of research and policy at the Fossil Fuel Treaty Initiative, said the conflict in the Middle East is making this “debt injustice and fossil fuel entrapment” even more evident.

      “What we have to start understanding is that both fossil fuels and debt are actually extractions from the Global South,” Sawas told the report’s launch during the World Bank and International Monetary Fund (IMF) Spring Meetings in Washington DC this month. “Many countries are paying more in debt servicing than they are getting in climate finance.”

        Since 2010, low and middle-income countries (LIMCs) have more than doubled their external debt, reaching an all-time high of $8.9 trillion two years ago. They paid about $415 billion in interest on that debt in 2024 – 2.4 times higher than a decade earlier.

        At the same time, in some cases like Colombia, Egypt and Jordan, austerity measures agreed as part of IMF and World Bank loan programmes restrict governments from investing in cleaner sources of revenue like renewable energy, the report says.

        Leading countries constrained by debt

        Colombia – one of the countries leading the global call for a transition away from fossil fuels – is facing precisely such financial barriers to achieving its transition, said Camilo Rodríguez, another of the report’s authors and a research analyst with Oil Change International.

        The country has halted all new oil and gas licences and published an energy transition plan estimating transition costs at about 7-10% of its GDP. Yet the government depends on fossil fuel revenues to service its $265-billion public debt, meaning it must find an alternative source of income to cover debt payments.

        Rodríguez said debt “is the main barrier nowadays to promote the energy transition and the industrialisation of the economy”.

        The South American country has only grown more dependent on fossil fuels over time, as they represented 36% of exports in 2001 and now account for about 52%. Austerity policies still in place after IMF loans have left very little room for investing in Colombia’s energy transition plan, the report says.

        Other countries have shown similar patterns. Jordan – despite its staggering public debt equivalent to 90% of GDP – became one of the fastest-growing markets for wind, solar and electric vehicles in the Middle East region. From 2014 to 2021, Jordan went from less than 1% of its electricity generation coming from renewables to 26%, benefiting from the significantly cheaper costs of installing wind and solar power compared with adding fossil fuel capacity.

        But Jordan’s high reliance on fossil fuel revenues created an incentive for policymakers to opt for expanding gas projects over renewables, and the country ended up suspending new licences for many solar and wind projects. In 2024, about 40% of government revenues were used to service debt.

        “This is not marginal – it is central to the fiscal system. It creates what I would describe as structural fiscal addiction,” said Ali Nasrallah, a policy and research manager at the Fossil Fuel Treaty Initiative. “The state depends on revenues from consumption that is economically, environmentally and socially harmful.”

        Gas flaring soars in Niger Delta post-Shell, afflicting communities  

        Another report by the Fossil Fuel Treaty Initiative, published in March, argues that debt entrapment in Africa also exacerbates gender injustice. Social consequences from fossil fuel extraction and use – such as displacement of communities or health harm from pollution – can have a substantial effect on local women while, at the same time, states face constraints to increasing social spending to support them.

        “African women are facing disproportionate impacts of the fossil fuel industry’s long-running legacy of violence and dispossession,” the report says. “But they are also leading the resistance to it,” it adds, with women-led coalitions in places like Uganda or the Niger Delta challenging major oil and gas projects.

        Policy recommendations

        As governments head to Santa Marta – where “gaps in the financial and investment system” are on the agenda – the Fossil Fuel Treaty Initiative recommends building international coalitions to address debt, reforming multilateral financial institutions and increasing funding commitments from donor nations.

        The proposed policies include debt cancellation as a way of creating fiscal space in the Global South, ending all international finance for fossil fuel expansion, establishing a binding mechanism on debt resolution at the UN, and advancing green industrialisation to replace fossil fuel revenues.

        “To dismantle carbon lock-in and debt at source, we need to recognise collectively that the escalating debt in the Global South is actually an injustice,” said Sawas of the Fossil Fuel Treaty Initiative. “We have to name the problem and be honest with ourselves – and that’s where the recommendation of debt cancellation is so critical.”

        Comment: Broken debt system must be fixed to confront future climate shocks

        As part of the new climate finance goal adopted at the COP29 climate summit in Baku, governments have already agreed to “remove barriers and address dis-enablers” faced by developing countries, including “limited fiscal space” and “unsustainable debt levels”.

        Building on this, any plan for a global roadmap for transitioning away from fossil fuels, such as the initiative proposed at COP30 by more than 80 governments, should address the debt crisis in the Global South, Sawas said. One alternative could be financing the rollout of renewables with more public grants rather than loans, she added.

        “We need to start properly funding renewable energy and diversification,” she said. “Currently it’s almost impossible for a lot of countries in the Global South to actually make the energy transition, because there’s no support structure.”

        China’s solar exports reach “gigantic” record in March as energy crisis bites 

        Published

        on

        China exported a record amount of solar components and photovoltaic panels last month, signalling that manufacturers are benefiting from stronger demand for clean energy technologies as the Iran war has caused oil and gas prices to soar and threatens supply shortages.

        The world’s second largest economy exported solar panels, cells and wafers capable of generating 68 gigawatts (GW) in March – the equivalent of Spain’s entire solar capacity, according to analysis of data from Chinese customs authority by global energy think-tank Ember. 

        March’s volume was more than double exports in February and 49% more than the previous record set in August 2025. Three-quarters of the increase came from exports to Asia and Africa. 

        As well as the Middle East conflict, a rush by Chinese manufacturers to export solar modules and cells before an export tax rebate ended on April 1 – adding 9% to solar panel costs – was a major driver of the export spike. 

          “The volumes exported are absolutely gigantic,” Euan Graham, senior analyst at Ember, told Climate Home News.

          “We will see over the coming months how much of that was linked to the tax rebate and how much of that is additional demand – that might vary by region. But certainly a big part of this is the response to the energy crisis,” he said. 

          China ends tax rebate on solar exports

          For Qi Qin, China analyst at the Centre for Research on Energy and Clean Air, March’s export surge was most likely driven by the end of the tax rebate, which brought forward demand, with high energy prices bolstering the trend.

          “Policy deadlines can create a sharp one-month jump in export, while by comparison, higher oil and gas prices caused by the war are… more likely to support demand over the medium term rather than explain such a strong spike in one single month,” she told Climate Home News.

          Earlier this year, the Chinese government announced that the solar export tax discount was coming to an end in an effort to prevent trade disputes and cut-throat competition for low-price exports among Chinese manufacturers.

          In a note at the time, Trivium China, an analysis firm that specialises in monitoring Chinese government policy, said Beijing had become frustrated with state tax resources being used to subsidise overseas consumers. “The rebate end date is all but certain to trigger one of the largest module production booms in history” to beat the April export price hike, it said.

          Solar manufacturing booms outside China

          Across the world, 50 countries set records for Chinese solar imports in March, while a further 60 saw the highest import levels in six months. Chinese solar exports to Africa reached 10GW last month, a 176% increase compared with the previous month while exports to Asia doubled to 39GW. 

          The increase is partly driven by growing solar manufacturing and assembly capacity outside China, as countries seek to produce more of their own solar capacity as well as export panels to other markets. In October last year, Chinese exports of solar cells and wafers overtook already assembled solar panels. In March alone, Chinese solar panel exports reached 32 GW while cells and wafers exports amounted to 36 GW. 

          India, which is rapidly building out a solar manufacturing industry, is increasingly importing wafers from China, which can be manufactured domestically into solar cells and assembled into panels. Chinese solar exports to India were up 141% in March compared to February.

          In Africa, Nigeria, Kenya and Ethiopia all imported over 1GW of solar for the first time in a single month, predominantly in the form of solar cells that are then assembled into panels. Exports to Nigeria, which is seeking to significantly ramp up its solar assembly capacity, rocketed 519% – the largest percentage increase. 

          “We’ve eagerly awaited the first signs of how countries around the world are responding to the energy crisis and this is just the first piece of evidence we have. The full effects of it will be revealing themselves for months to come, both in terms of the immediate consumer response and also more structural government policy changes,” said Graham of Ember.
