Despite scientific and economic evidence to the contrary, they claim this global warming limit cannot be met. Ignoring the well-established scientific methodologies for calculating emission reductions, they assert it is too difficult to calculate the emission reductions needed to meet the 2°C limit.
The authors propose different metrics of measuring climate targets implying that this could lead to a relaxation of the required level of emissions reductions. However, the scientific literature shows clearly that including other metrics (objectives, such as reducing sea level rise, reducing ocean acidification) will likely increase the level of emission reductions needed.
