Climate Home News, 5 August 2025: IPCC’s input into key UN climate review at risk as countries clash over timeline. 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. Read more here
