New research shows that hotter temperatures and erratic rainfall are pressuring cocoa production in West African countries that supply around 70% of the main ingredient for chocolate, quadrupling the price of cocoa over the past two years and making Valentine’s Day a costlier enterprise worldwide.

Studies released this week by charity Christian Aid and nonprofit news organisation Climate Central found that extreme temperatures have become more frequent in the region, affecting cacao trees which do not thrive well in temperatures above an optimal range of 18–32 degrees Celsius.

Kristina Dahl, vice president for science at Climate Central, urged sweethearts swapping chocolate on Valentine’s Day to consider the broader impact of climate change. “These heat extremes, driven by burning fossil fuels, are not just affecting the environment – they’re directly impacting the farmers and communities who rely on cacao production for their livelihoods,” she said.

High heat drives record prices

An analysis of daily maximum temperatures over the past decade revealed that climate change added on average at least three weeks above 32C each year, adding six extra weeks of high temperatures in 2024 alone, according to Climate Central. This occurred during the main cacao crop season from October to March in the West African cocoa-producing nations of Côte d’Ivoire, Ghana, Cameroon and Nigeria.

In late December 2024, a new record for cocoa prices was set at $12,605 per tonne and they have remained stubbornly high since, Christian Aid said.

DRC’s huge Green Corridor project lacks buy-in from forest communities

Excessive heat significantly hinders photosynthesis and increases water stress, the Climate Central report emphasised, resulting in shrivelled flowers and smaller, rotted cacao pods, further reducing the quality and quantity of the harvest.

While high heat is not conducive for cacao cultivation, more erratic and heavier rainfall also degrades growing conditions, encouraging the spread of disease and reducing trees’ pod production, Christian Aid said in a separate report.

A strong carbon tax on shipping can give hope to climate-vulnerable communities

Consistent warm and humid conditions are ideal for the crop’s growth, requiring annual rainfall of between 1,500 and 2,000 mm, with a dry spell lasting no longer than three months.

Changing weather patterns have tightened global cocoa supplies and fuelled rising prices for chocolate – a by-product of cocoa – yet that has not put off sweet-toothed consumers. The chocolate market grew by 3.8% between 2018 and 2023, the researchers found. Last year, it was worth $109 billion – and it is estimated to grow to $145 billion by the end of this decade.

Adaption limits

Farmers in West Africa are finding it hard to adapt to the shifting climate – and through their associations, have called for direct access to more financial support. Only 0.3% of climate finance was targeted at family farmers globally in 2021, according to the group Family Farmers for Climate Action.

Industry officials have also called for farmers to be paid a fair price for their cocoa as they rarely benefit from commodity price increases, receiving just 6% of the price paid for a chocolate bar on average.

Ibrahima Coulibaly, president of ROPPA, a West African family farmers’ organisation, said decades of under-investment and unfair trade mean cocoa farmers are highly vulnerable to climate impacts. To safeguard chocolate supplies, “governments need to work with – and invest in – farmers and their organisations” and ensure “farmers are paid a fair price for their cocoa”, he added.

For example, they could use the extra money to scale up nature-friendly practices – such as planting shade trees to protect cocoa pods from heat and sunlight – which are key to adaptation, Coulibaly noted.

Changing incentives

Sustainable agriculture is essential to addressing climate impacts on cocoa production in the West Africa region, Climate Home reported last year. Current incentives, such as subsidies for fossil-fuel based fertilisers and tax breaks, have enabled deforestation and water depletion as farmers cleared more land to grow trees, as well as boosting planet-heating emissions.

To shift the cocoa industry in a greener direction, the Rainforest Alliance recommends taxing chemical fertilisers and pesticides, and ending mono-cropping practices which can harm soil health and biodiversity.

It says subsidies should instead be provided for practices that improve soil conditions and local ecosystems, including growing cover crops that maintain soil nutrition over the winter months, and shade trees to protect seedlings from harsh weather.

In the longer term, the main way to protect cocoa production – “a vital livelihood for many of the poorest people around the world” – and keep chocolate affordable is for countries to curb rising global emissions of the greenhouse gases heating up the planet, said Osai Ojigho, director of policy and public campaigns at Christian Aid.

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.”
