How then, and why, have climate scientists come to a consensus about a very complex scientific problem that the scientists themselves acknowledge has substantial and fundamental uncertainties?

Society faces very substantial scientific uncertainty, which is the root cause of the scientific disagreements.

The very high significance levels of model - observation discrepancies in LT and MT trends that were obtained in some studies (e.g., Douglass et al., 2008; McKitrick et al., 2010) thus arose to a substantial degree from using the standard error of the model ensemble mean as a measure of uncertainty, instead of the standard deviation or some other appropriate measure of ensemble spread.

The very high significance levels of model — observation discrepancies in LT and MT trends that were obtained in some studies (e.g., Douglass et al., 2008; McKitrick et al., 2010) thus arose to a substantial degree from using the standard error of the model ensemble mean as a measure of uncertainty, instead of the ensemble standard deviation or some other appropriate measure for uncertainty arising from internal climate variability... Nevertheless, almost all model ensemble members show a warming trend in both LT and MT larger than observational estimates (McKitrick et al., 2010; Po - Chedley and Fu, 2012; Santer et al., 2013).

Dr. Judith Curry: The uncertainties in ocean heat content below 700 m are very substantial, see http://judithcurry.com/2014/01/21/ocean-heat-content-uncertainties/... The role of internal ocean behavior in climate change was almost completely neglected up the AR4; the AR5 takes it a bit more seriously.

While such «tipping points» (Kemp, 2005) are impossible to identify without substantial uncertainties, they may lead to irreversible effects such as biodiversity loss or, at the very least, impacts that have a slow recovery (e.g., on soils and corals).

The issue of tropospheric temperature trends is very difficult and has received a great deal of attention by researchers and also assessment reports; the problems are much worse for humidity and few people have even attempted to do anything with tropospheric humidity trends owing to inaccuracies in the radiosonde humidity measurements and substantial uncertainties in the satellite retrievals.

Although the most advanced theoretical climate models still leave uncertainty, particularly about the sign and magnitudes of the effects, on GHG feedbacks, of some low - and high - clouds, a consensus began to develop that threats of resulting increases in global temperature — and the very large risks associated with their possible consequences — deserved substantial increase in attention.

Most organizations are very familiar with uncertainty of many different kinds and even qualitative guidance can have substantial value in the design of robust adaptation strategies which minimize vulnerability to both climate variability and change.
