The economic models that are used to inform climate policy currently contain an unhealthy dose of wishful thinking. Technologies that remove carbon dioxide from the air are assumed in the models that avoid dangerous climate change – but such technologies do not yet exist and it is unclear whether they could be deployed at a meaningful scale. – Tim Kruger

The 200% increase in fossil fuel emissions Murry Salby claims is about 20% in reality, and the constant CO2 growth rate he found actually increased by roughly 20% as well over the same time period.

It is therefore suggested to use either the more robust tropospheric temperature or ocean surface temperature in studies of climate sensitivity. – Cederlof, Bengtsson, Hodges

We survey the rationale and diversity of approaches for tuning, a fundamental aspect of climate modeling which should be more systematically documented and taken into account in multi-model analysis. – Hourdin et al.
