The «pause» and the many observation - based studies showing a much lower 2xCO2 ECS than previously predicted by the models cited by IPCC in AR4, gave IPCC the possibility for a paradigm shift to refocus away from its CAGW premise to one of reduced warming projections based on the lower observed CO2 sensitivity.

«[1] Projections of 21st century warming may be derived by using regression - based methods to scale a model's projected warming up or down according to whether it under - or over-predicts the response to anthropogenic forcings over the historical period.

And the longer this «pause» in warming continues while GHG emissions continue unabated, the more «uncertain» become the model - based attribution estimates of IPCC and, hence, the projections for the future.

However, dry - spell duration and warming trend effects on vegetation productivity may be at least partly offset by rising atmospheric CO2 effects on plants (Bachelet et al., 2001; Thuiller et al., 2006b), leading to sometimes contrasting projections for deserts that are based on different modelling techniques that either incorporate or ignore CO2 - fertilisation effects.

The projected future warming projections (for the end of this century) have been reduced a bit, starting from essentially the same base (AR5: 1986 - 2005 = +0.26 °C versus AR4: 1980 - 1999 = +0.23 °C):
