German government climate adviser claims 2-degree target is science-based

Das ist nicht richtig

Oliver Geden writes in the Guardian:

Compared to its influence on other public policies and national-level policymaking, the influence of science on international climate policy has always been relatively strong, both in terms of defining basic causal chains as well as in setting the short- to medium-term agenda. The 2°C target and the emissions budgets derived from it are only the most visible expressions of this.

The 2-degree target is entirely arbitrary, “plucked out of thin air” as Phil Jones described it.
