Commentary: Climate Research Scores an Own Goal – And Doesn't Want to Admit It

The climate science community has, in essence, scored an own goal by clinging to an implausibly high CO2 emissions scenario for years, only to now retire it. This move has predictably emboldened critics of climate action, who are seizing upon it to argue that the threat of climate change has been exaggerated. While the research community is partly to blame for this self-inflicted wound due to communication missteps, the core issue lies in the prolonged use of an extreme scenario that required the hypothetical extraction of all global coal reserves, even from Antarctica, to be realized.

For years, this scenario was often mislabeled as 'business-as-usual,' a communication breakdown that obscured its extreme nature. Critics rightly pointed out the unrealistic assumptions and the problematic way the scenario was used in many climate studies. The reluctance of many climate researchers to acknowledge these valid criticisms for an extended period, resorting to flimsy justifications, has only exacerbated the situation.

At the Neue Zürcher Zeitung, we believe it is crucial for scientific integrity that such unrealistic scenarios are retired. However, the manner in which this has unfolded, and the subsequent reaction from climate change skeptics, highlights a broader challenge in communicating complex scientific findings. The scientific community must learn from this episode to ensure greater transparency and accuracy in its projections, thereby safeguarding its credibility and fostering more constructive public discourse on climate change.
