In a significant step towards understanding the evolving climate crisis, approximately 600 experts convened Monday to begin work on the next major United Nations climate report. Their efforts come at a challenging time when the international consensus on global warming faces opposition from significant political figures, including US President Donald Trump, who has repeatedly dismissed climate science as a “hoax.”
Speaking at the opening of the five-day meeting in Saint-Denis, a Paris suburb, French Ecological Transition Minister Monique Barbut emphasized the critical importance of the scientists’ work, particularly as multilateral cooperation on climate issues has weakened in recent years.
“There is also something that should concern us all: the rise of climate-related disinformation on our social media, in our newspapers and even at the heart of our political institutions,” Barbut told the assembled experts. “Too many people deny the results of your work.”
The gathering brings together specialists from more than 100 countries under the banner of the Intergovernmental Panel on Climate Change (IPCC), the UN body responsible for assessing the science related to climate change. Their task is particularly challenging given the political headwinds, most notably from the United States.
During a speech at the United Nations in September, President Trump called climate change the “greatest con job ever” and a “hoax,” rhetoric that directly contradicts the scientific consensus that has been established through decades of rigorous research and analysis.
The political interference extends beyond rhetoric to affect key personnel. One of the co-chairs of an IPCC working group is US climate expert Katherine Calvin, who was dismissed from her position as chief scientist at NASA following budget cuts ordered by the Trump administration.
“The statements, for example, from the American administration on the origin of climate change, the fact that it’s a hoax, if you will, we still find that quite surprising,” remarked an official from the French Ecological Transition Ministry who spoke on condition of anonymity.
This level of opposition from a major global power creates significant complications for climate scientists. The United States, as a key member nation, possesses what effectively amounts to veto power in international climate discussions, potentially influencing the direction and conclusions of the upcoming report.
The previous IPCC assessment, published in 2023, delivered a stark warning that the world was on track to exceed the critical 1.5°C warming threshold by 2030. This benchmark, established in the Paris Climate Agreement, represents the level beyond which many climate impacts become significantly more severe and potentially irreversible.
Since that report’s publication, the situation has grown more urgent. The United Nations now indicates that this crucial threshold will be breached earlier than previously predicted. Crossing this threshold substantially increases the risk of extreme weather events including violent storms, catastrophic floods, prolonged droughts, and irreversible damage to natural ecosystems worldwide.
The meeting in France marks the beginning of a lengthy and meticulous process that will culminate in the IPCC’s Seventh Assessment Report (AR7), scheduled for publication in 2028 or 2029. This comprehensive document will provide policymakers with the most up-to-date scientific understanding of climate change, its impacts, and potential mitigation strategies.
Despite the political challenges, the work of these scientists remains essential for informing global climate policy. Their findings help shape international agreements, national policies, and provide the evidence base needed for effective climate action across governments, businesses, and communities worldwide.
As this latest assessment cycle begins, the scientists face the dual challenge of conducting rigorous research while navigating an increasingly polarized political environment that sometimes questions the very foundations of their work.

It’s alarming to see climate disinformation spreading, even at the highest levels of government. The IPCC experts are our best resource for understanding the realities of global warming. Their work should be the foundation for our response, not political rhetoric.
It’s deeply concerning to see political leaders like Trump dismissing the scientific consensus on climate change. The IPCC experts are doing vital work to address this global crisis, and we need to empower them, not undermine their efforts.
I agree. Ignoring the evidence and peddling disinformation is irresponsible and puts us all at risk. We need to take this issue seriously and act on the scientific findings.
This is a concerning trend of climate change denial and disinformation. The IPCC experts are our best resource for understanding the realities of global warming, and their work should be the foundation for our response, not political rhetoric.
Absolutely. Ignoring the scientific consensus and promoting misinformation is irresponsible and puts us all at risk. We need to take this issue seriously and empower our policymakers to implement evidence-based solutions.
This is a concerning trend of climate change denial and disinformation. It’s crucial that we rely on the scientific consensus from IPCC experts rather than political rhetoric that dismisses the evidence.
Agreed. We need to counter misinformation with facts and empower people to make informed decisions about the very real climate challenges we face.
The IPCC is doing crucial work to understand the climate crisis. It’s deeply concerning that their efforts are being undermined by disinformation and political posturing. We need to take this issue seriously and act on the scientific evidence.
Absolutely. Dismissing climate change as a ‘hoax’ is irresponsible and dangerous. We must listen to the experts and implement evidence-based policies to address this global challenge.
Trump’s refusal to acknowledge climate change is deeply troubling. The IPCC scientists are doing vital work to understand and address this global crisis. We need strong leadership that listens to the experts.
Absolutely. Ignoring climate science in favor of political posturing is irresponsible and puts us all at risk. We must elevate evidence-based policymaking on this urgent issue.
This is a troubling trend of climate denial and misinformation. The IPCC scientists are our best resource for understanding the realities of global warming. Their work should be the foundation for our response, not political rhetoric.
The rise of climate denial is very concerning. We need to heed the warnings from the IPCC scientists and take decisive action to address this crisis, rather than dismissing it as a ‘hoax’.
Agreed. Ignoring the experts and peddling disinformation is a dangerous path. We must be guided by the scientific evidence, not political agendas.
It’s disheartening to see political figures like Trump undermining the vital work of the IPCC. We should be empowering our scientists and policymakers to tackle climate change, not sowing doubt and confusion.
The IPCC scientists are doing crucial work to understand and address the climate crisis. It’s deeply troubling to see their efforts undermined by political figures who dismiss the scientific evidence. We need to elevate the voices of the experts, not the deniers.
