Climate Myths Debunked: What the IPCC Really Says

Cal Thomas has once again launched a criticism of scientists, media and politicians. He claims that the Intergovernmental Panel on Climate Change has abandoned its most dramatic forecast, calling it “implausible. ” Thomas interprets this as evidence that the climate crisis is overblown. The IPCC does not issue predictions; it presents scenarios that illustrate how different levels of greenhouse‑gas emissions could affect the planet by 2100. In its 2011 report, four such pathways were outlined. The most extreme scenario would raise global temperatures by between 3. 3 and 5. 7 degrees Celsius, while the least extreme would see an increase of about 1. 5 degrees.

Recent findings from the panel indicate that the highest scenario is now considered unlikely, thanks to global efforts such as stricter emissions rules and a shift away from coal power. However, Thomas ignores that the panel also points out that the lowest scenario is similarly improbable because many countries have not yet cut emissions enough to keep warming below 1. 5 degrees. In short, the IPCC’s update is a reflection of progress and remaining challenges, not proof that climate science is exaggerated. The panel’s language about “implausibility” simply signals where current policies fall short, not that the danger has vanished. Critics like Thomas miss this nuance and instead spread misinformation about what climate science actually means for the future.
