Governments have again failed to agree on a schedule for producing key climate science reports as deep divergences blocked progress at a meeting of the U.N.’s Intergovernmental Panel on Climate Change (IPCC) last week.
At the talks in Sofia, Bulgaria, most countries supported a faster process that would see three flagship reports assessing the state of climate science delivered by mid-2028, in time for the next global stocktake – the UN’s scorecard of collective climate action.
But a group of high-emitting developing countries made up of China, India, Saudi Arabia, Russia and South Africa – backed by Kenya – opposed an accelerated timeline, citing concerns that it would be harder to include scientists from the Global South, three sources present at the talks told Climate Home.
Governments were unable to reach a decision for the second time this year after “fraught talks” in January ended with the same outcome. The issue will be debated again at the next gathering in February 2025, while a separate expert meeting is tasked with drafting the outline of those reports by the end of 2024.
Fight over climate science
Adão Soares Barbosa, IPCC representative for Timor-Leste within the Least Developed Countries (LDCs) group, expressed his disappointment over the lack of agreement in Sofia resulting from “strong polarisation in the room”.
“If the assessment reports are not able to feed information into the global stocktake process, what are they good for?” he said, speaking to Climate Home.
Joyce Kimutai, who represented Kenya at the Sofia talks, said her country’s opposition to the proposed shortened timeline was “absolutely not intended to frustrate the process” but to highlight the challenges countries with more limited resources would be facing.
“With such a tight timeline, it is likely that we will produce a report that is not comprehensive, not robust. We found that very problematic,” she told Climate Home on Monday.

The primary purpose of the IPCC is to provide credible scientific assessments to the UN’s climate body (UNFCCC) and national decision-makers. The findings of its reports – which are usually compiled over several years by scientists working on a voluntary basis around the world – have been highly influential. They synthesise the latest research on climate change, as well as efforts to curb planet-heating emissions and adapt to the impacts of global warming.
The sixth series, whose final report was issued in March 2023, played a prominent role in informing the first UNFCCC global stocktake which resulted in governments agreeing for the first time to begin “transitioning away from fossil fuels” at COP28 in Dubai last December.
But some fossil fuel-rich countries like Saudi Arabia – which have pushed back against clear language on the need to cut production – have previously opposed strong recognition of IPCC reports in UNFCCC negotiations.
The UN climate body has officially requested that its scientific counterpart align its activities with the timeline of the next global stocktake. The IPCC’s input will be “invaluable” for the international review of climate action, Simon Stiell, chief of the UN climate body, told the IPCC meeting in January.
Reputation ‘at risk’
As he opened the session in Sofia, the IPCC chair Jim Skea warned of a “complex and testing” agenda.
The discussion over the report production schedule would have “far-reaching implications in terms of the timeliness of our products, and the inclusivity of both our own processes and the science that is being assessed”, he added.
Scientists and government officials were presented with a proposal drafted by the IPCC secretariat – its administrative arm – which would see the assessment reports completed between May and August 2028. That would be a few months before the global stocktake process is scheduled to end in November 2028.
The IPCC must produce its flagship report in time for the next UN global stocktake
A majority of countries, including EU member states, the UK, the US and most vulnerable developing nations, supported the proposal, stressing the importance of the scientific reports feeding into the global stocktake, according to sources and a summary of discussions by the IISD’s Earth Negotiations Bulletin. Many supporters added that the IPCC’s reputation would otherwise be at risk.
Small island states and least-developed countries argued that IPCC input is crucial for those that lack capacity to produce their own research and are most vulnerable to the immediate impacts of climate change, according to the IISD summary.
But a dozen developing countries – with India, Saudi Arabia and China being the most vocal – opposed speeding up the process, arguing that more time is needed to ensure greater inclusion of experts and research from the Global South, which would result in “robust and rigorous” scientific output.
South Africa, Russia, Kenya, Algeria, Burundi, Congo, Jordan, Libya and Venezuela expressed similar views, according to IISD.
More time for more voices
India said that “producing the best science needs time, haste leads to shoddy work”, while Saudi Arabia claimed that the shortened timeline would “lead to incomplete science and would be a disservice to the world”, according to the IISD summary of the discussions.
Kenya’s Kimutai told Climate Home that producing scientific literature and reviewing submissions takes a lot of time and, unlike their counterparts in richer countries, scientists in the Global South can rarely count on the help of junior researchers at well-funded institutions.
“We love this process – we find it important,” she added, “but we’re trying to say that, while it may be an easy process in other regions, it is not for us”.

The IPCC has long struggled with ensuring adequate representation of expert voices from the Global South. Only 35% of the authors working on its sixth and latest assessment report hailed from developing countries, according to a study published in the journal Climate, up from 31% in the previous cycle.
In Sofia, several delegates pointed out that the IPCC is working to improve inclusivity and that a slight extension of the schedule would not be the solution. Similar views were aired by forty IPCC authors from developing countries in a letter circulated ahead of last week’s talks, urging countries to ensure that the reports are ready in time for the global stocktake.
While recognising concerns over the inclusion of under-represented communities, they argued that it would not be achieved by allowing more time but through “deliberate efforts to counterbalance long-standing inequalities” in the research world.
Writing for Climate Home, Malian scientist Youba Sokona, one of the letter’s authors, warned that the IPCC risks losing its relevance and influence over global climate policy-making if its output cannot be used in the global stocktake.

Despite lengthy exchanges, scientists in Sofia could not find a solution and decided to postpone a decision on the timeline until the next IPCC session in February 2025, when countries will also need to agree on the outline of the reports’ content.
Kenya’s Kimutai has proposed a compromise that would see reports on adaptation and mitigation completed in time for the global stocktake, with a third on the physical science of climate change coming in later.
Richard Klein, a senior researcher at the Stockholm Environment Institute (SEI) and a lead author of previous IPCC reports, told Climate Home the ongoing row was “problematic”. “With these delays, a shorter [report] cycle in time for the global stocktake may not be feasible anymore, which in turn makes it less likely we will see ambitious nationally-determined contributions (NDCs) after that process,” he warned.
Expert scientists from the IPCC will meet again this December at a “scoping” session to sketch out a framework for what the assessment reports should include.
Barbosa of Timor-Leste is worried that those discussions will also become “heavily politicised”.
“We are concerned that high-emitting developing countries will try water down the work on emission-cutting measures and keep out strong messages on things like the need to phase out fossil fuels,” he told Climate Home.

DeBriefed 15 August 2025: Raging wildfires; Xi’s priorities; Factchecking the Trump climate report
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Blazing heat hits Europe
FANNING THE FLAMES: Wildfires “fanned by a heatwave and strong winds” caused havoc across southern Europe, Reuters reported. It added: “Fire has affected nearly 440,000 hectares (1,700 square miles) in the eurozone so far in 2025, double the average for the same period of the year since 2006.” Extreme heat is “breaking temperature records across Europe”, the Guardian said, with several countries reporting readings of around 40C.
HUMAN TOLL: At least three people have died in the wildfires erupting across Spain, Turkey and Albania, France24 said, adding that the fires have “displaced thousands in Greece and Albania”. Le Monde reported that a child in Italy “died of heatstroke”, while thousands were evacuated from Spain and firefighters “battled three large wildfires” in Portugal.
UK WILDFIRE RISK: The UK saw temperatures as high as 33.4C this week as England “entered its fourth heatwave”, BBC News said. The high heat is causing “nationally significant” water shortfalls, it added, “hitting farms, damaging wildlife and increasing wildfires”. The Daily Mirror noted that these conditions “could last until mid-autumn”. Scientists warn the UK faces possible “firewaves” due to climate change, BBC News also reported.
Around the world
- GRID PRESSURES: Iraq suffered a “near nationwide blackout” as elevated power demand – due to extreme temperatures of around 50C – triggered a transmission line failure, Bloomberg reported.
- ‘DIRE’ DOWN UNDER: The Australian government is keeping a climate risk assessment that contains “dire” implications for the continent “under wraps”, the Australian Financial Review said.
- EXTREME RAINFALL: Mexico City is “seeing one of its heaviest rainy seasons in years”, the Washington Post said. Downpours in the Japanese island of Kyushu “caused flooding and mudslides”, according to Politico. In Kashmir, flash floods killed 56 and left “scores missing”, the Associated Press said.
- SOUTH-SOUTH COOPERATION: China and Brazil agreed to “ensure the success” of COP30 in a recent phone call, Chinese state news agency Xinhua reported.
- PLASTIC ‘DEADLOCK’: Talks on a plastic pollution treaty have failed again at a summit in Geneva, according to the Guardian, with countries “deadlocked” on whether it should include “curbs on production and toxic chemicals”.

Factchecking Trump’s climate report
A report commissioned by the US government to justify rolling back climate regulations contains “at least 100 false or misleading statements”, according to a Carbon Brief factcheck involving dozens of leading climate scientists. The report, compiled in two months by five hand-picked researchers, inaccurately claims that “CO2-induced warming might be less damaging economically than commonly believed” and misleadingly states that “excessively aggressive [emissions] mitigation policies could prove more detrimental than beneficial”80
Spotlight
Does Xi Jinping care about climate change?
This week, Carbon Brief unpacks new research on Chinese president Xi Jinping’s policy priorities.
On this day in 2005, Xi Jinping, a local official in eastern China, made an unplanned speech when touring a small village – a rare occurrence in China’s highly-choreographed political culture.
In it, he observed that “lucid waters and lush mountains are mountains of silver and gold” – that is, the environment cannot be sacrificed for the sake of growth.
(The full text of the speech is not available, although Xi discussed the concept in a brief newspaper column – see below – a few days later.)
In a time where most government officials were laser-focused on delivering economic growth, this message was highly unusual.
Forward-thinking on environment
As a local official in the early 2000s, Xi endorsed the concept of “green GDP”, which integrates the value of natural resources and the environment into GDP calculations.
He also penned a regular newspaper column, 22 of which discussed environmental protection – although “climate change” was never mentioned.
This focus carried over to China’s national agenda when Xi became president.
New research from the Asia Society Policy Institute tracked policies in which Xi is reported by state media to have “personally” taken action.
It found that environmental protection is one of six topics in which he is often said to have directly steered policymaking.
Such policies include guidelines to build a “Beautiful China”, the creation of an environmental protection inspection team and the “three-north shelterbelt” afforestation programme.
“It’s important to know what Xi’s priorities are because the top leader wields outsized influence in the Chinese political system,” Neil Thomas, Asia Society Policy Institute fellow and report co-author, told Carbon Brief.
Local policymakers are “more likely” to invest resources in addressing policies they know have Xi’s attention, to increase their chances for promotion, he added.
What about climate and energy?
However, the research noted, climate and energy policies have not been publicised as bearing Xi’s personal touch.
“I think Xi prioritises environmental protection more than climate change because reducing pollution is an issue of social stability,” Thomas said, noting that “smoggy skies and polluted rivers” were more visible and more likely to trigger civil society pushback than gradual temperature increases.
The paper also said topics might not be linked to Xi personally when they are “too technical” or “politically sensitive”.
For example, Xi’s landmark decision for China to achieve carbon neutrality by 2060 is widely reported as having only been made after climate modelling – facilitated by former climate envoy Xie Zhenhua – showed that this goal was achievable.
Prior to this, Xi had never spoken publicly about carbon neutrality.
Prof Alex Wang, a University of California, Los Angeles professor of law not involved in the research, noted that emphasising Xi’s personal attention may signal “top” political priorities, but not necessarily Xi’s “personal interests”.
By not emphasising climate, he said, Xi may be trying to avoid “pushing the system to overprioritise climate to the exclusion of the other priorities”.
There are other ways to know where climate ranks on the policy agenda, Thomas noted:
“Climate watchers should look at what Xi says, what Xi does and what policies Xi authorises in the name of the ‘central committee’. Is Xi talking more about climate? Is Xi establishing institutions and convening meetings that focus on climate? Is climate becoming a more prominent theme in top-level documents?”

New York Already Denied Permits to These Gas Pipelines. Under Trump, They Could Get Greenlit
The specter of a “gas-for-wind” compromise between the governor and the White House is drawing the ire of residents as a deadline looms.
Hundreds of New Yorkers rallied against new natural gas pipelines in their state as a deadline loomed for the public to comment on a revived proposal to expand the gas pipeline that supplies downstate New York.
New York Already Denied Permits to These Gas Pipelines. Under Trump, They Could Get Greenlit
A “critical assessment” report commissioned by the Trump administration to justify a rollback of US climate regulations contains at least 100 false or misleading statements, according to a Carbon Brief factcheck involving dozens of leading climate scientists.
The report – “A critical review of impacts of greenhouse gas emissions on the US climate” – was published by the US Department of Energy (DoE) on 23 July, just days before the government laid out plans to revoke a scientific finding used as the legal basis for emissions regulation.
The executive summary of the controversial report inaccurately claims that “CO2-induced warming might be less damaging economically than commonly believed”.
It also states misleadingly that “excessively aggressive [emissions] mitigation policies could prove more detrimental than beneficial”.
Compiled in just two months by five “independent” researchers hand-selected by the climate-sceptic US secretary of energy Chris Wright, the document has sparked fierce criticism from climate scientists, who have pointed to factual errors, misrepresentation of research, messy citations and the cherry-picking of data.
Experts have also noted the authors’ track record of promoting views at odds with the mainstream understanding of climate science.
Wright’s department claims the report – which is currently open to public comment as part of a 30-day review – underwent an “internal peer-review period amongst [the] DoE’s scientific research community”.
The report is designed to provide a scientific underpinning to one flank of the Trump administration’s plans to rescind a finding that serves as the legal prerequisite for federal emissions regulation. (The second flank is about legal authority to regulate emissions.)
The “endangerment finding” – enacted by the Obama administration in 2009 – states that six greenhouse gases are contributing to the net-negative impacts of climate change and, thus, put the public in danger.
In a press release on 29 July, the US Environmental Protection Agency said “updated studies and information” set out in the new report would “challenge the assumptions” of the 2009 finding.
Carbon Brief asked a wide range of climate scientists, including those cited in the “critical review” itself, to factcheck the report’s various claims and statements.
