Fish are evolving ever smaller in order to survive temperature increases, new research warns. It’s a biological shift that will rob billions of meals from those who rely on fish for protein.
In the world’s waters, fish are making a quiet, biological retreat. The once simple rules of the ocean—grow larger than potential predators—are being rewritten as temperatures reach record highs. Desperate to survive, fish are hitting the fast-forward button on life in a biological shift that will soon impact what ends up on dinner tables globally.

The Invisible Infrastructure of Climate Resilience
Katharine K. Wilkinson’s new book explores the movement through climate grief and describes how to look inward with care and outward with curiosity and courage.
After years working in the climate movement, Katharine K. Wilkinson noticed that advocates consistently lacked the emotional stamina and support needed to stay active, inspired and connected to others engaged in climate work.

UN chief says fossil fuel industry must cut methane for warming “relief”
UN chief António Guterres called on Tuesday for stronger action to cut emissions of planet-heating methane, taking aim at the fossil fuel industry’s practices and profits, and pointing to coal, oil and gas as the root of today’s climate and energy crises.
In a major speech at London Climate Action Week, with the British capital under a heatwave warning, the UN Secretary-General said countries had not done enough to reduce greenhouse gas emissions in line with what is needed to keep warming below the globally agreed goal of 1.5C.
“The task before us is to strictly limit the overshoot, shorten its duration, and bring temperatures down below 1.5 degrees Celsius as fast as possible,” Guterres said. One way of doing that, he added, is by cutting methane emissions first.
He noted that methane – a potent greenhouse gas that traps around 80 times more heat than carbon dioxide – is responsible for around one-third of global warming but breaks down in the atmosphere within a decade or two.
“That means that aggressive cuts could produce visible temperature relief within a generation,” the UN chief emphasised, launching a global call to action on methane covering fossil fuel production, agriculture and organic waste disposal.
Of the three main sources of methane, he singled out the fossil fuel industry, where he said “the most immediate gains can be made”.
He cited the International Energy Agency (IEA) finding that around 70% of oil and gas methane emissions can be eliminated using existing technology, mostly at low or no net cost. This is because the gas leaking from coal mines and oil and gas production facilities can be captured and then used or sold.
Despite this, in 2025 alone, Guterres said some 167 billion cubic metres of gas were flared – as much as Africa consumes in a year.
“I am urging the fossil fuel industry to step up and do what is long overdue,” added the UN chief, whose term ends this year.
Guterres said voluntary action “is no longer enough” and there were similar global precedents for getting rid of harmful substances, including leaded petrol and ozone-depleting chemicals. “Methane pollution must be next,” he emphasised.
Methane emissions stuck at highs
The latest Global Methane Tracker report from the IEA shows that methane emissions from fossil fuels remained at very high levels in 2025, with no sign of a decline globally despite progress in some countries. In 2025, energy generated 41% of global methane emissions, followed by agriculture (40%) and waste (17%).
On Tuesday, a World Bank tracker showed that global gas flaring rose for the third year in a row in 2025, wasting an estimated $54 billion worth of gas by burning it off.
Demetrios Papathanasiou, the World Bank Group’s global director for energy, said that at a time when many countries are struggling to expand their access to affordable and reliable energy, “the economic development costs of continued flaring are simply too high”. “The gas currently flared could be captured to power industries and businesses, create jobs and strengthen energy security,” he said in a statement.
As well as easing climate change, the IEA says capturing waste methane could help improve gas market security after Iran’s near-closure of the Strait of Hormuz removed close to 20% of global liquefied natural gas supply from the market.
The prime minister of Barbados, Mia Mottley, last year called on leaders at the UN General Assembly to draw up a “legally binding global agreement” to reduce methane emissions, an idea that is also supported by France.
Mottley’s “legally binding” methane pact faces barriers, but smaller steps possible
However, Guterres stopped short of supporting such a solution on Tuesday, throwing his weight instead behind a proposal for governments to set a new global standard for net near-zero methane emissions across the value chain in the oil and gas sector.
This initiative, outlined in a report on the new call to action, would establish a common, internationally recognised methane intensity benchmark, for use by both producers and consumers. Compliance with the standard would then become a condition for financing, procurement and long‑term market access.
Voluntary action ‘not enough’
In recent years, countries and companies willing to act on the methane problem have teamed up on the Global Methane Pledge, which aims to cut methane emissions by 30% by 2030 from 2020 levels, and the UAE-led Oil and Gas Decarbonisation Charter, signed by over 50 oil and gas companies. But their success has been limited in real terms.
Speaking at a separate event on Monday, Jonathan Banks, vice president of methane pollution prevention at the Clean Air Task Force (CATF), said the global pledge had been successful in creating “high-level political buy-in”, raising more money to detect methane emissions and helping countries plug their sources.
But it “is not there to be this all-encompassing binding treaty that drives emissions down”, he added.
At last year’s COP30, 11 countries representing around 10% of global oil production and 18% of gas exports signed a pledge to “drastically reduce” methane emissions in the fossil fuel sector, including by eliminating routine gas flaring and venting.

The United Nations Environment Programme (UNEP) also runs a system that detects methane leaks around the world. It has issued more than 5,000 alerts across 33 countries, but received responses in only 12% of cases.
Meghan Demeter, a programme manager at the UNEP service, said on Monday that countries face several barriers to responding to the alerts, including limited capacity to interpret the data and act on it, as well as funding shortages, particularly among national oil companies.
A senior UN official told journalists that existing initiatives on methane had raised awareness of the issue but had failed to deliver the emissions cuts needed. “’It’s absolutely critical that governments step in and strongly regulate the oil and gas sector,” he added.
Norway leads the way
As an example of how this could work, the call to action report singled out Norway, which banned routine flaring in 1971, imposed a tax on emissions from petroleum production and transport in 1991, and increased its tax on flaring and methane emissions in 2017. It now has one of the lowest methane emissions intensities of upstream oil and gas production in the world.
The report said that if all countries matched Norway’s standards, global methane emissions from oil and gas operations could fall by roughly 90%.

It added that China, Canada, the United Arab Emirates and Qatar reduced or maintained their methane emissions from oil and gas production between 2023 and 2024, even as output increased, indicating a decline in the emissions intensity of their operations.
On Monday, the Fossil Fuel Regulatory Programme (FFRP), a UNEP-backed initiative that works with governments to strengthen regulatory frameworks for cutting methane emissions from their energy sectors, added Egypt, Brazil, and Bosnia and Herzegovina to its existing partners, Ghana, Kazakhstan and Iraq.
Windfall tax on fossil fuel profits
Guterres also made a strong push for states to hit the very deep pockets of fossil fuel companies with windfall taxes, as countries like the UK, Italy or Spain have done in recent years.
He said fossil energy giants had reaped ”extraordinary profits”, with the eight biggest making an extra $6.5 billion in the first quarter of this year alone, which included only one month of the Middle East crisis which has pushed up oil prices.
“These are windfall gains born of pain – of instability, hardship and dependence. I urge governments to tax them,” said the UN chief.
He added that the proceeds should be used “where they belong: helping vulnerable families and communities, and accelerating the shift to clean, affordable energy”.

China’s coal-chemicals boom risks repeating the mistakes of the past
Aiqun Yu, Christine Shearer and Joe Hittinger work at Global Energy Monitor, a US-based organisation that seeks to provide the worldwide energy transition with transparent data and analysis.
With global oil and gas prices soaring at the start of the Iran war, China quietly broke ground on three major coal-to-gas and coal-to-chemical projects worth roughly $10 billion in two regions with abundant coal resources.
But as a Chinese saying goes, “three feet of ice does not form in a single day”. China’s push to use coal as a substitute for imported oil and gas has been gathering momentum since the Russia-Ukraine war began in 2022, prompting a recalibration of energy security priorities in Beijing and beyond.
The policy raises new concerns, threatening China’s climate goals and growing reputation as a global clean energy leader by creating renewed demand for coal.
A new expansion wave
Over the past three years, China has entered a new cycle of investment in so-called “modern coal chemicals”, differentiated from conventional coal chemicals. Four pathways – coal-to-gas, coal-to-liquids, coal-to-olefins, and coal-to-ethylene glycol – account for the bulk of new modern coal-chemical capacity under development.
According to Global Energy Monitor data, proposed and under-construction coal-to-gas capacity is approaching three times current operating capacity. Together, 34 projects under active consideration represent more than 1 trillion yuan ($150 billion) in planned investment and could add roughly 300 million tonnes of annual coal demand if completed, equivalent to South Africa’s entire coal mining capacity.
Most projects are in Xinjiang, Inner Mongolia, Shaanxi and Ningxia, regions with plentiful coal resources and relatively low mining costs. Xinjiang has emerged as the epicentre of the new boom, accounting for more than half of all proposed modern coal chemical projects.
Why the world abandoned coal chemicals
Coal chemicals are often presented as an emerging industry, but the technologies themselves are more than a century old.
Earlier “conventional” coal chemistry was a byproduct of coking, a process run primarily for iron and steel making. “Modern” coal chemistry instead uses gasification to convert coal into synthesis gas, a versatile building block for fuels, plastics, fertilisers and other chemicals that would traditionally be made from oil or gas.
These modern processes were developed in the early 20th century and expanded during periods of wartime fuel shortages. For example, Germany relied heavily on synthetic fuels during the Second World War while South Africa developed similar technologies in the apartheid era to reduce vulnerability to international sanctions.


Once cheap oil and gas became widely available, however, most countries moved away from coal chemicals, which required large amounts of energy, water and capital investment, and generally produced more pollution and carbon emissions than the conventional alternatives.
Today, only a handful of commercial coal gasification facilities operate outside China.
China has already tested this theory once
The current expansion is not China’s first attempt to build a major coal chemical industry.
A previous boom emerged during the 2010s, driven by many of the same arguments: high oil prices, concerns over energy security and expectations that technological improvements would unlock a new era of coal-based industrial growth.

The outcome was far from successful. Dozens of projects were proposed, but many were delayed, suspended or scrapped before completion, and there were difficulties among those that did get off the ground.
Three of China’s four operating coal-to-gas projects reportedly spent much of the past decade operating at a loss, and several large coal chemical facilities generated only marginal returns despite government support.
Policy support is driving the revival
Backers say technological improvements have made the industry more competitive than it was a decade ago.
Yet coal chemical projects remain highly dependent on oil and gas prices. When international prices rise, coal-derived products can appear competitive. When prices fall, the economics often deteriorate rapidly.
More than changes in technology, government policy has played a pivotal role in the sector’s revival.
Following power shortages in 2021 and the energy market disruptions that followed Russia’s invasion of Ukraine, energy security became a national priority. Coal production expanded, particularly in western China, boosted by government support.
China’s solar exports reach “gigantic” record in March as energy crisis bites
A key policy change in 2022 exempted coal used as industrial feedstock from certain energy consumption controls, easing regulatory pressure on coal chemical projects.
The impact of such measures highlights the degree to which coal chemicals depend on expansive and favourable policy treatment to remain viable.
At the same time, the current expansion is creating new demand for an industry confronting structural decline as China races to renewables in electricity generation.
The cost to China’s climate leadership
Converting coal into fuels and petrochemical products also releases substantially more carbon dioxide than conventional oil- and gas-based alternatives, which themselves are a major source of emissions.
Proponents argue that coupling production with green hydrogen and carbon capture could resolve the emissions problem, but the arithmetic doesn’t support this.
Sinopec’s flagship Dalu coal-to-olefins plant, paired with a 10,000 tonne-per-year green hydrogen demonstration, displaces less than 2% of the plant’s annual coal use. Replicating this across the proposed buildout would consume enormous quantities of clean energy just to partially decarbonise an inherently dirty process.
China could instead leverage that same industrial capacity and policy support to lead the development of cleaner chemical pathways, such as green ammonia for fertiliser, bio-based and CO2-derived feedstocks for plastics, and e-fuels or biofuels where liquid fuels are still needed.
Rather than locking in another generation of coal-dependent infrastructure, China should learn from the lessons of the past and seek a cleaner and more viable industrial future.
