Additionally, the observed surface temperature changes over the past decade are within the range of model predictions (Figure 6) and decadal periods of flat temperatures during an overall long - term warming trend are predicted by climate models (Easterling & Wehner 2009).

A significant and serious concern among mainstream climate scientists in this regard is the inability of the models to predict climate surprises, that is, rapid non-linear changes in the climate system that have happened in the historical climate record and that may be triggered by current human activities.

Moreover, if we agree the climate models can not skillfully predict natural variations, why would you conclude that they can skillfully predict changes in climate statistics needed by the impacts and policy communities?

The loud divergence between sea - level reality and climate change theory — the climate models predict an accelerated sea - level rise driven by the anthropogenic CO2 emission — has been also evidenced in other works such as Boretti (2012a, b), Boretti and Watson (2012), Douglas (1992), Douglas and Peltier (2002), Fasullo et al. (2016), Jevrejeva et al. (2006), Holgate (2007), Houston and Dean (2011), Mörner 2010a, b, 2016), Mörner and Parker (2013), Scafetta (2014), Wenzel and Schröter (2010) and Wunsch et al.

Changes in ocean chemistry, which can be described through the Revelle buffer factor [1], limit oceanic removal of CO2 [2], while the potential for terrestrial vegetation to take up CO2 is also predicted by some models to fall as the climate warms [3], although the size of this feedback is uncertain [4].

In addition, Earth system models predict carbon loss by placing vegetation at a given point, and then changing various climate properties above it.

Thus, while the model predicts that the perceived level of scientific agreement acts as a key psychological motivator, its effect on support for action is assumed to be fully mediated by key beliefs about climate change (H3).

Yet, when scientists examine the empirical temperature measurement datasets, it becomes readily apparent that changes in CO2 levels are not generating the expected changes in global temperatures, as predicted by the immensely powerful and sophisticated (and incredibly costly) climate models.

One approach to this problem is «downscaling,» a procedure in which climate changes in large - scale atmosphere and ocean conditions predicted by a global model are used as input to a fine - scale regional model that does resolve tropical cyclones.

And then you have to accept that the climate models do a very poor job of predicting CO2 - AGW because the equation introduced by Lacis and Hansen in 1974 to predict cloud albedo change from pollution is useless even though Sagan derived it.
