Research published this week in Earth System Dynamics reports that the most sensitive climate models overestimate global warming during the last 50 years.
Three scientists from the University of Exeter studied the output of complex climate models and compared them to temperature observations since the 1970s.
Recent developments in cloud modelling have produced models that portray very large sensitivity to rising greenhouse gas concentrations.
A subset of models even showed that a doubling of CO2 could lead to over 5°C of warming, questioning whether the goals of the Paris agreement are achievable even if nations do everything they can.
