The quiz was inspired by Professor Hans Rosling’s  Factfulness Quiz on global health . He used to educate his students and the rest of society, especially decision-makers, on fundamental facts and predictions on global health, but also on their pre-conceptions and biases using a quiz format. Thereby, he also demonstrated the need for continued education to make the right decisions in a fast-changing world.
The following Fakten-Quiz zur Klimakrise: is a subjective selection of questions, which, however, follows a “narrative” supporting the conclusion of UN secretary-general António Guterres, that we experience a “direct existential threat” . The “narrative” here is a connected set of facts, predictions, or expert opinions based on empirical science, which are relevant in the context of human biology and culture. The information was selected with due caution to make sure it is reliable, valid and representative, and can be traced back to its source publication.

- 2019-07-11: In Question 6, the “range” of the increase of the global mean surface temperature was previously interpreted as interquartile range, ie as the 50% uncertainty interval with the 25% quantile as lower and the 75% quantile as upper limit. After personal communication with scientists of the Climate Action Tracker organization, the interpretation was updated to an approximate 67% confidence interval with the 16% quantile as the lower limit and the 82.5% quantile as the upper limit corresponding to the likely range of the IPCC Fifth Assessment Report.

After personal communication, Prof. Steffen replied that he had used Prof. Schellnhuber’s estimate. This means, the two estimates are not independent predictions, but – in my opinion – can be interpreted in the way, that Prof. Steffen supports the estimate by Prof. Schellnhuber as plausible.
