Claim by: Right-Leaning Media and Donald Trump
Posts circulating through right-leaning media outlets and social media users, amplified by commentary from President Donald Trump and climate skeptics, claim the Intergovernmental Panel on Climate Change (IPCC) admitted its catastrophic climate projections were false, exaggerated, or intentionally misleading. Articles such as the Daily Sceptic article argued that climate “doomsday scenarios” were “never going to happen” and that the climate movement was always about “control.”
Explanation
This claim is false and highly misleading.
The IPCC did not admit to lying or fabricating climate risks. What changed was the scientific assessment of a particular worst-case emissions scenario known as RCP8.5/SSP5-8.5. That scenario assumed extremely high long-term fossil fuel consumption, especially massive global coal expansion, that now appears increasingly unlikely due to real-world developments.
Scientists revised the plausibility of the most extreme pathway because:
- Renewable energy expanded faster than expected,
- Coal growth slowed in many regions,
- Electric vehicles accelerated globally, and
- Governments implemented climate policies that altered projected emissions trends.
This is normal scientific refinement, not evidence of fraud.
Even the right-leaning American Enterprise Institute article “RCP8.5 Is Officially Dead” does not claim climate science was fabricated. Instead, it argues that the highest-end emissions pathway became less plausible as global energy patterns evolved.
The IPCC continues to warn that climate change remains a severe and escalating threat. Its ongoing Seventh Assessment Report (AR7) process emphasizes increasing risks from heatwaves, droughts, biodiversity loss, sea-level rise, and cascading climate impacts.
Crucially, the IPCC never presented RCP8.5 as a guaranteed prediction. IPCC reports use multiple scenarios to model possible futures depending on human choices and policy outcomes. Worst-case scenarios are intended to examine risks if emissions continue to rise aggressively, not to claim that the outcome is inevitable.
The reduced likelihood of the most extreme warming pathway reflects changes in emissions behavior, technology, and policy, not an admission that prior climate science was a hoax.
Even revised estimates of approximately 2.4°C to 3.5°C warming by 2100 remain highly dangerous for ecosystems, agriculture, infrastructure, weather systems, and economies worldwide.
Claims that the IPCC “lied” or admitted climate projections were fake originated largely from ideological pseudoscience and political framing, including pieces from the Daily Sceptic and coverage by Fox News, not from any statement by the IPCC itself.
Conclusion
Fact or Fiction? Fiction. The IPCC did not admit it lied about climate change. Scientists updated emissions scenarios because real-world energy trends changed. The most extreme warming pathway became less plausible due to technological and policy developments, not because climate science was fabricated or intentionally deceptive.
