In addition, some studies also use the estimated ocean heat uptake since 1955 based on Levitus et al. (2000, 2005)(Chapter 5), and temperature changes in the free atmosphere (Chapter 3; see also Table 9.3).

If you look at the Fig. 3a in our review (red lines at the top) you see that many previous estimates based on the observed warming / ocean heat uptake had a tendency to peak at values below 3 °C (that review is from 2008).

Additional carbon dioxide uptake causes direct changes in seawater acid - base and inorganic carbon chemistry in a process termed ocean acidification.

«Model - Based Evidence of Deep - Ocean Heat Uptake During Surface - Temperature Hiatus Periods.»

The US CLIVAR / OCB Southern Ocean Working Group was formed to identify critical observational targets and develop data / model metrics based on the currently available observational data, both physical and tracer, and the assimilative modeling (re) analyses, and evaluate and develop our understanding of the importance of mesoscale eddies in the heat and carbon uptake and of the response of the Southern Ocean to a changing climate, using high - resolution numerical studies and theory.

Based on the rather vast uncertainties in aerosol forcing, and the substantial discrepancies between model projections of ocean heat uptake and measured heat uptake (ARGO), it strikes me as bizarre that the IPCC insists on excluding the possibility of quite low sensitivity, when there is a wealth of evidence for fairly low sensitivity.

No, the model result is only used to estimate ocean heat uptake in the base period, which is before observational data was available.

The analysis uses a global energy budget model that links ECS and TCR to changes in global mean surface temperature (GMST), radiative forcing and the rate of ocean heat uptake between a base and a final period.

Based on most of the reconstructions of the tropical oceans I have seen, the current rate of ocean heat uptake is perfectly consistent with long term recovery.
