UK’s ‘slowing’ climate ambition

MIXED SIGNALS: The Climate Change Committee (CCC) has warned the perception of the UK’s climate ambition has “suffered from mixed messages” following “new fossil-fuel developments and the prime minister’s speech to soften some net-zero policies”, reported the Press Association. In a report on progress made at the COP28 climate summit in Dubai last year, the advisory body said “decisions to approve a new coal mine and licence new oil and gas production” have contributed to “a perception of slowing UK climate ambition by members of the international community”, the outlet noted.

‘GROSSLY IRRESPONSIBLE’: It comes as the UK this week allocated another 24 licences to major oil companies for the right to drill for fossil fuels in the North Sea, the Guardian reported. According to the North Sea Transition Authority, oil and gas could be produced within the decade under the licences, the outlet noted. The move “angered MPs and environmental campaigners”, who called the move “grossly irresponsible”, it added.

IMF WARNING: Meanwhile, Pierre-Olivier Gourinchas, chief economist of the International Monetary Fund, has “warned UK chancellor Jeremy Hunt against cutting taxes, arguing the country needs to curb public borrowing and prioritise spending in areas such as health, education and tackling climate change”, reported the Financial Times

Around the world

  • ENVOY IN EMPLOY: US president Joe Biden has appointed his clean energy adviser John Podesta to succeed John Kerry as the nation’s top climate diplomat, reported the Financial Times. Podesta will take on the role in addition to his current White House job overseeing $370bn in spending on clean energy under the Inflation Reduction Act, noted the New York Times.
  • SOLAR SUCCESS: China’s installed wind and solar capacity is set to overtake coal for the first time this year, according to Reuters. Bloomberg reported that China installed more solar panels in 2023 than any other nation has built in total.
  • ITALY-AFRICA SUMMIT: At a summit of African leaders in Rome, Italy unveiled a plan to use its climate fund to transform into “an energy hub” that creates “a bridge between Europe and Africa”, reported Climate Home News. Observers warned that the plan presents “enormous ambiguities” that leave the door open to fossil-fuel investment.
  • TRACTOR TUMULT: Farmers protesting across Europe have “won their first concession”, reported the Guardian, with the EU announcing a delay in rules for setting aside land for nature. Carbon Brief’s Cropped newsletter has more on how far-right political groups are aiming to capitalise on the outrage.
  • PAKISTAN ELECTION: Ahead of Pakistan’s general election on 8 February, two major political parties have “prominently highlighted the importance of dealing with climate change-related issues in their manifestos”, reported the Press Trust of India.
  • FIGHTING FIRES: More than a hundred firefighters battled a forest fire in the Los Alerces national park in northern Patagonia, reported BBC News. La Nación noted that an “unusual heatwave” has brought temperatures of up to 40C to the region.

2.47 million square kilometres

The “missing” area of Antarctic sea ice in July 2023, relative to the long-term average, according to a Carbon Brief guest post. This is larger than the area of Algeria, the 10th largest country in the world.


Latest climate research

  • Melting of a glacier in Switzerland over just two years has left it “irrevocably lost” as a record of past air pollution from ice cores, a Nature Geoscience study reported. 
  • Economic recovery spending in the wake of the Covid-19 pandemic “missed many opportunities to advance climate adaptation and resilience” (A&R), according to a Nature Sustainability study. Analysis of around 8,000 government policies across 88 countries found that just 10-11% had “direct A&R benefits”.
  • A study in Earth’s Future warns that extreme heat and thawing permafrost will pose “severe threats” to global rail and road infrastructure as the climate warms.

Captured

The US has far more LNG capacity in the pipeline than any other country

The US is already the world’s largest exporter of liquified natural gas (LNG) and has more additional capacity “proposed” (dark blue on the chart) than any other nation, according to a new Q&A by Carbon Brief. The article unpacked the implications of the surprise move, made late last week by US president Joe Biden, for a “temporary pause” on the expansion of LNG export terminals.

Spotlight

Surging methane from the world’s wetlands

This week, to mark UN World Wetlands Day, Carbon Brief speaks to a scientist helping uncover how methane emissions from wetlands are rising in a changing climate.  

In 2020 and 2021, the rate at which methane levels in the atmosphere increased hit record highs.

The rise between 2019 and 2020 was “roughly a doubling” of the annual growth rate, Dr Benjamin Poulter, a research scientist at the NASA Goddard Space Flight Center, explained to Carbon Brief. This was “unexpected and caught the scientific community by surprise”.

In December 2022, a Nature study by Poulter and colleagues found that “wetlands appear to have played a key role, explaining around 50% of the jump from 2019 to 2020”, he said. Further work – currently undergoing peer-review – has suggested that the world’s wetlands were the main driver behind the growth between 2020 and 2021 as well.

Wetlands are areas of land that are either permanently or seasonally inundated with water. They are found across the world, but predominantly in lush landscapes in the tropics and frozen “permafrost” expanses in the higher latitudes of the northern hemisphere.

The near-constant saturation means that decomposing organic matter in the soil releases methane instead of CO2. This methane can diffuse from the water into the atmosphere, be emitted through grass-like plants or abruptly as bubbles. Research has also shown that trees can transport methane from the soil to the atmosphere – or potentially even produce it within their stems.

La Niña’s influence

There appears to be two main reasons why wetlands produced more methane over 2020-22, Poulter explained – a combination of a La Niña event “causing wetlands to expand in the tropics” and climate change “causing warming in all parts of the world, and especially in the high latitudes”.

La Niña is the cold-water counterpart to the natural El Niño climate phenomenon. They are known collectively as the El Niño-Southern Oscillation (ENSO). In general, an El Niño event “causes wetland methane emissions to decrease in tropical regions due to drying”, said Poulter, while La Niña causes emissions “to increase as wetlands expand”. There are regional variations that complicate things a little, he added.

In the high latitudes, “ENSO has less of an impact”, explained Poulter, but rapid warming in this region “is likely driving increasing trends in wetland methane emissions” – as well as “changing the seasonal onset of wetland methane production as the permafrost thaws earlier, deeper and freezes later in the year”.

Methane feedback

The overall increase in wetland methane emissions in recent years is “expected from wetland model projections”, noted Poulter. He published a study last year that indicated the rise may be part of an extended climate-wetland methane “feedback” where global warming drives greater wetland methane emissions, which – in turn – drives further warming.

For 2023 and 2024, the methane growth rate is likely to be influenced by “the El Niño phase of ENSO and the record-breaking global air temperatures”, Poulter said. Last year, for example, “droughts in Central America and Amazonia disrupted shipping and livelihoods, and likely led to decreased tropical wetland methane emissions”.

The US Global Monitoring Laboratory is due to release its final atmospheric concentration data for 2023 in April. This will help confirm understanding of wetland methane emissions, Poulter said, and “whether the El Niño-induced drought impacts on tropical wetlands caused the atmospheric growth rate of methane to decrease” last year.

Watch, read, listen

OVERSTATE: In this interactive, a group of Bloomberg journalists investigated how “dozens” of UK wind farms have routinely overestimated how much power they can produce.

BIG OIL: DeSmog uncovered evidence that fossil-fuel companies funded climate research as far back as 1954, further suggesting their long-standing knowledge of global warming.

‘IMPORTANT QUESTIONS’: In a Nature news feature, journalist Gayathri Vaidyanathan looked at the “agonising choices” over how the UN loss-and-damage fund will be allocated.

Drought Turns Southeastern US Into ‘Tinderbox’ as Wildfires Rage

Published

on

Weather extremes fuel wildfires that have burned through tens of thousands of acres across Georgia, Florida and other states.

Drought and fire are a dangerous duo. The Southeastern United States is witnessing this firsthand as several major blazes burn tens of thousands of acres across the parched region, destroying homes and prompting evacuations in some areas. Florida and Georgia have been particularly hard hit, and strong winds and unusually low humidity have made it difficult to combat the flames.

Night Skies and Shifting Stars: How Indigenous Celestial Knowledge Tracks a Changing Climate

Published

on

When the land no longer answers the stars the way it once did, Indigenous peoples are among the first to notice — and the first to ask why.

A Sky Full of Knowledge

Look up on a clear night on Turtle Island and you’re seeing a sky that has guided human life for thousands of years. Across Indigenous nations in Canada, detailed systems of celestial knowledge developed not as abstract science but as living, practical guides —telling people when to plant, when to harvest, when herds would move, and when ice would come. This astronomical knowledge was woven into language, ceremony, and everyday life, passed down through generations with remarkable precision.

The Mi’kmaq and the Celestial Bear

Among the Mi’kmaq of Atlantic Canada, star stories are ecological calendars, precise and functional. The story of Muin and the Seven Bird Hunters connects the annual movement of what Western astronomy calls Ursa Major to the seasonal cycle of hunting and harvest: the bear rises in spring, is hunted through summer, and falls to earth in autumn. This knowledge was brought to broader public attention in 2009 during the International Year of Astronomy, when Mi’kmaq Elders Lillian Marshall of Potlotek First Nation and Murdena Marshall of Eskasoni First Nation shared the story through an animated film produced at Cape Breton University narrated in English, French, and Mi’kmaq.¹ The story encodes specific observations about when and where to hunt, and which species to expect at which time of year. It is science in narrative form.

The Anishinaabe and the Seasonal Star Map

Among the Anishinaabe peoples of the Great Lakes and northern Ontario, celestial knowledge forms part of a comprehensive seasonal understanding. Knowledge keepers like Michael Wassegijig Price of Wikwemikong First Nation have described how Anishinaabe constellations  quite different from those of Western astronomy connect the movement of the heavens to naming ceremonies, seasonal gatherings, and land practices.² The Royal Astronomical Society of Canada now offers planispheres featuring Indigenous constellations from Cree, Ojibwe, and Dakota sky traditions, recognizing their value as both cultural heritage and ecological knowledge systems.³

When the Stars and the Land Fall Out of Rhythm

Here’s the challenge that climate change has introduced: the stars still move on their ancient, reliable schedule. But the land no longer always responds as expected. Migratory birds that once arrived when certain constellations appeared are now showing up earlier or later. Ice that once formed in predictable windows is forming weeks late, or not at all. Berry harvests, fish runs, animal migrations, all once timed by celestial cues accumulated over millennia are shifting. Indigenous knowledge holders across Canada describe this as a kind of dissonance: the sky remains faithful, but the land has changed.⁴

Long-Baseline Ecological Records

Far from being historical curiosity, Indigenous celestial knowledge systems are now being recognized by researchers as long-baseline ecological calendars —records of how nature behaved over centuries, encoded in story and ceremony. When an Elder observes that a particular star rising no longer predicts the arrival of certain geese, that observation represents a departure from a pattern that may have held true for hundreds of years. The Climate Atlas of Canada integrates Indigenous knowledge observations alongside western climate data, recognizing that both contribute meaningfully to understanding ecological change.⁵

Keeping the Knowledge Alive

Language revitalization and land-based education programs are helping ensure this knowledge reaches the future. From youth astronomy nights on-reserve to the integration of Indigenous sky stories in school curricula, there is growing recognition that these knowledge systems belong to what comes next, not only what came before. As Canada grapples with accelerating ecological change, the quiet precision of thousands of years of skyward observation offers something no satellite can fully replicate: a continuous record of the relationship between the cosmos and a living land.

World ‘will not see significant return to coal’ in 2026 – despite Iran crisis

Published

on

A much-discussed “return to coal” by some countries in the wake of the Iran war is likely to be far more limited than thought, amounting to a global rise of no more than 1.8% in coal power output this year.

The new analysis by thinktank Ember, shared exclusively with Carbon Brief, is a “worst-case” scenario and the reality could be even lower.

Separate data shows that, to date, there has been no “return to coal” in 2026.

While some countries, such as Japan, Pakistan and the Philippines, have responded to disrupted gas supplies with plans to increase their coal use, the new analysis shows that these actions will likely result in a “small rise” at most.

In fact, the decline of coal power in some countries and the potential for global electricity demand growth to slow down could mean coal generation continues falling this year.

Experts tell Carbon Brief that “the big story isn’t about a coal comeback” and any increase in coal use is “merely masking a longer-term structural decline”.

Instead, they say clean-energy projects are emerging as more appealing investments during the fossil-fuel driven energy crisis.

‘Return to coal’

The conflict following the US-Israeli attacks on Iran has disrupted global gas supplies, particularly after Iran blocked the strait of Hormuz, a key chokepoint in the Persian Gulf.

A fifth of the world’s liquified natural gas (LNG) is normally shipped through this region, mainly supplying Asian countries. The blockage in this supply route means there is now less gas available and the remaining supplies are more expensive.

(Note that while the strait usually carries a fifth of LNG trade, this amounts to a much smaller share of global gas supplies overall, with most gas being moved via pipelines.)

With gas supplies constrained and prices remaining well above pre-conflict levels, at least eight countries in Asia and Europe have announced plans to increase their coal-fired electricity generation, or to review or delay plans to phase out coal power.

These nations include Japan, South Korea, Bangladesh, the Philippines, Thailand, Pakistan, Germany and Italy. Many of these nations are major users of coal power.

Such announcements have triggered a wave of reporting by global media outlets and analysts about a “return to coal”. Some have lamented a trend that is “incompatible with climate imperatives”, while others have even framed this as a positive development that illustrates coal’s return “from the dead”.

This mirrors a trend seen after Russia’s invasion of Ukraine in 2022, which many commentators said would lead to a surge in European coal use, due to disrupted gas supplies from Russia. 

In fact, despite a spike in 2022, EU coal use has returned to its “terminal decline” and reached a historic low in 2025.

Gas to coal

So far, the evidence suggests that there has been no return to coal in 2026.

Analysis by the Centre for Research on Energy and Clean Air found that, in March, coal power generation remained flat globally and a fall in gas-fired generation was “offset by large increases in solar and wind power, rather than coal”.

However, as some governments only announced their coal plans towards the end of March, these figures may not capture their impact.

To get a sense of what that impact could be, Ember assessed the impact of coal policy changes and market responses across 16 countries, plus the 27 member states of the EU, which together accounted for 95% of total coal power generation in 2025.

For each country, the analysis considers a maximum “worst-case” scenario for switching from gas to coal power in the face of high gas prices.

It also considers the potential for any out-of-service coal power plants to return and for there to be delays in previously expected closures as a result of the response to the energy crisis.

Ember concludes that these factors could increase coal use by 175 terawatt hours (TWh), or 1.8%, in 2026 compared to 2025.

(This increase is measured relative to what would have happened without the energy crisis and does not account for wider trends in electricity generation from coal, which could see demand decline overall. Last year, coal power dropped by 63TWh, or 0.6%.)

Roughly three-quarters of the global effect in the Ember analysis is from potential gas-to-coal switching in China and the EU.

Other notable increases could come from switching in India and Indonesia and – to a lesser extent – from coal-policy shifts in South Korea, Bangladesh and Pakistan.

However, widely reported policy changes by Japan, Thailand and the Philippines are estimated to have very little, if any, impact on coal-power generation in 2026. The table below briefly summarises the potential for and reasoning behind the estimated increases in coal generation in each country in 2026.

Dave Jones, chief analyst at Ember, stresses that the 1.8% figure is an upper estimate, telling Carbon Brief:

“This would only happen if gas prices remained very high for the rest of the year and if there were sufficient coal stocks at power plants. The real risk of higher coal burn in 2026 comes not from coal units returning…but rather from pockets of gas-to-coal switching by existing power plants, primarily in China and the EU.”

Moreover, Jones says there is a real chance that global coal power could continue falling over the course of this year, partly driven by the energy crisis. He explains:

“If the energy crisis starts to dent electricity demand growth, coal generation – as well as gas generation – might actually be lower than before the crisis.”

‘Structural decline’

Energy experts tell Carbon Brief that Ember’s analysis aligns with their own assessments of the state of coal power.

Coal already had lower operation costs than gas before the energy crisis. This means that coal power plants were already being run at high levels in coal-dependent Asian economies that also use imported LNG to generate electricity. As such, they have limited potential to cut their need for LNG by further increasing coal generation.

Christine Shearer, who manages the global coal plant tracker at Global Energy Monitor, tells Carbon Brief that, in the EU, there is a shrinking pool of countries where gas-to-coal switching is possible:

“In Europe, coal fleets are smaller, older and increasingly uneconomic, while wind, solar and storage are becoming more competitive and widespread.”

In the context of the energy crisis, Italy has announced plans to delay its coal phaseout from 2025 to 2038. This plan, dismissed by the ECCO thinktank as “ineffective and costly”, would have minimal impact given coal only provides around 1% of the country’s power. 

Notably, experts say that there is no evidence of the kind of structural “return to coal” that would spark concerns about countries’ climate goals. There have been no new coal plants announced in recent weeks.

Suzie Marshall, a policy advisor working on the “coal-to-clean transition” at E3G, tells Carbon Brief:

“We’re seeing possible delayed retirements and higher utilisation [of existing coal plants], as understandable emergency measures to keep the lights on, but not investment in new coal projects…Any short-term increase in coal consumption that we may see in response to this ongoing energy crisis is merely masking a longer-term structural decline.”

With cost-competitive solar, wind and batteries given a boost over fossil fuels by the energy crisis, there have been numerous announcements about new renewable energy projects since the start of war, including from India, Japan and Indonesia

Shearer says that, rather than a “sustained coal comeback” in 2026, the Iran war “strengthens the case for renewables”. She says:

“If anything, a second gas shock in less than five years strengthens the case for renewables as the more secure long-term path.”

Jones says that Ember expects “little change in overall fossil generation, but with a small rise in coal and a fall in gas” in 2026. He adds:

“This would maximise gas-to-coal switching globally outside of the US, leaving no possibility for further switching in future years. Therefore, the big story isn’t about a coal comeback. It’s about how the relative economics of renewables, compared to fossil fuels, have been given a superboost by the crisis.”
