Dozens of countries have called out growing ‘coordinated attacks’ by fossil fuel interests aimed at undermining the role of climate science in the UN negotiations at the mid-year talks in Bonn. Under the banner of ‘Friends of Science’, in an overflowing press conference room lined with negotiators and civil society supporters, diplomats from Fiji, Nepal, the European Union, Switzerland, Sierra Leone and Panama vowed to ensure that decision-making in the UN climate process remains based on the ‘best available science’. That includes reports from the Intergovernmental Panel on Climate Change (IPCC), the UN’s climate science body, they said. While steering clear of singling out any specific country, they said efforts to cast doubt on established scientific concepts, such as the 1.5 global warming limit, are led by ‘the usual suspects’ and those who think ‘science threatens their economic prospects’. Saudi Arabia and India have opposed calls in draft texts to encourage scientific work on scenarios that would minimise the magnitude and duration of any overshoot of 1.5C, according to one negotiator in the room and summaries of closed-door discussions published by a reporting service. UN chief António Guterres conceded last year that a temporary breach of the key warming limit is inevitable, while urging countries to redouble efforts to bring temperatures back down. ‘Polluted narrative’ Scientists have long established that burning fossil fuels is the primary cause of man-made climate change and a rapid shift away from oil, coal and gas is essential to curb global warming. Saudi Arabia is dependent on oil and gas exports, while India largely relies on coal to power its economic development. One negotiator said that research on how climate action can be equitable for developing countries, produced by Indian universities, had been published too late to be incorporated into the last IPCC assessment report in 2023. This incident led the Indian government to try and discredit the IPCC, they said. Some Indian scientists have argued that the IPCC’s scenarios are unfair on developing countries.

(Photo: Teo Ormond-Skeaping) The ‘Friends of Science’ coalition stressed that the 1.5C goal of the Paris Agreement cannot be negotiated, as the survival of the most climate vulnerable communities is at stake if it is permanently breached. ‘Science tells us that 1.5C is a hard limit for many countries, including the small island developing states and least developed countries,’ said Manjeet Dhakal, a negotiator for Nepal. ‘We still have a chance to keep 1.5 degrees in reach and minimise the overshoot if we act fast and drastically.’ Long-running IPCC standoff While diplomats claimed attacks on science are broadening, one long-standing issue of contention is whether the latest assessment reports of the IPCC will be ready in time for the next UN global stocktake due to start this November and end in 2028. This matters because, as some experts have pointed out, previous IPCC findings played a key role in the first such exercise, which culminated at COP28 in Dubai in the landmark agreement on transitioning away from fossil fuels in energy systems. The UN climate process needs ambition – the law demands it Since the start of the latest IPCC assessment cycle, known as AR7, a battle over the timing has dragged on for over two years at successive IPCC meetings, with governments repeatedly failing to find a breakthrough. A large majority of nations have been pushing for an accelerated timeline that would ensure the AR7 reports can be fed into the UN’s global stocktake. But a group of countries, including Saudi Arabia, India, China, Russia and Kenya, have said at previous IPCC meetings they want a longer process, arguing a fast-tracked assessment would put a burden on developing countries with limited resources. Science and the stocktake That fight has now bled into the Bonn talks where governments began discussing the arrangements for the next stocktake. At a session earlier this week, most developed countries, Latin American and small island states, and the world’s poorest nations emphasised the assessment of collective climate action must be guided by the ‘best available science’ – code for the findings of the IPCC reports. The Maldives, speaking for small island states, said IPCC science remains ‘essential to the integrity, credibility and usefulness’ of the stocktake. AILAC said that starting the process ‘on the right footing’ requires a political decision on the timeline to deliver the AR7 reports in time. Switzerland said IPCC reports ‘ask more than is politically comfortable, but that is precisely why they must guide every decision we make’. Saudi Arabia, however, said no particular scientific input – and in particular what comes out of the IPCC – should be prioritised. Similarly, India warned against creating ‘some kind of preferred hierarchy’ in the role that any specific source of information should play in the process. Ghana’s Antwi-Boasiako Amoah, who chairs the African Group, told a press conference on Tuesday that some countries think rushing to get IPCC inputs into the global stocktake could ‘undermine or compromise the IPCC process’. ‘Africa is for science,’ he said, without saying where the continent stands on the IPCC timeline. Crunch talks in October At the ‘Friends of Science’ press conference, Dhakal pushed back on the idea that science would have to be rushed to be incorporated. He said the IPCC leadership has ‘perfectly made it clear’ that they can deliver the report before the global stocktake. ‘It is the scientists who are saying they can deliver it on time,’ he said.

Andreas Sieber, head of political strategy at campaigning group 350.org, told Climate Home News that the debate may sound procedural, ‘but it is anything but’. ‘Science is the backbone of the Paris Agreement ambition cycle, and the evidence assessed through AR7 will help determine not only the emissions pathways countries pursue, but also how the world responds to mounting climate losses and who receives support,’ he said in Bonn.
