Victor and Kennel argue that the target of limiting global warming below 2°C relative to pre-industrial levels (the “2°C goal,” or rather, “limit”), adopted by the international community, should be dropped.

They put forward two main reasons: that it is no longer feasible to meet the 2°C limit, in large part because there has been insufficient action to date, and that the 2°C limit is not measurable and cannot be translated into emission limits for countries and regions.

Both major reasons put forward to drop the 2°C limit are flawed or incorrect.
