Observational records of ocean heat content show that ocean warming is accelerating Climate change from human activities mainly results from the energy imbalance in Earth's climate system caused by rising concentrations of heat-trapping gases. About 93% of the energy imbalance accumulates in the ocean as increased ocean heat content (OHC). The ocean record of this imbalance is much less affected by internal variability and is thus better suited for detecting and attributing human influences (1…

Ocean surface energy balance allows a constraint on the sensitivity of precipitation to global warming
- Environmental ScienceNature communications
- 2021
Using observations of the ocean surface energy balance as a hydrological constraint, it is found that historical warming intensified precipitation at a rate of 0.68 ± 0.51% K−1, which is slightly higher than the multi-model mean calculation for the historical climate.
Enhanced hydrological cycle increases ocean heat uptake and moderates transient climate change

It is demonstrated that surface salinification driven by the amplified dry conditions, primarily in the subtropical ocean, accelerates ocean heat uptake and suggests that model spread in near-term climate sensitivity may be due in part to hydrological cycle and salinity differences.

Improved estimates of upper-ocean warming and multi-decadal sea-level rise
- Environmental ScienceNature
- 2008
Improved estimates of near-global ocean heat content and thermal expansion for the upper 300 m and 700’m of the ocean for 1950–2003 are reported, using statistical techniques that allow for sparse data coverage and applying recent corrections to reduce systematic biases in the most common ocean temperature observations.
Quantification of ocean heat uptake from changes in atmospheric O2 and CO2 composition

An independent estimate based on atmospheric O2 and CO2 measurements suggests that ocean warming is at the high end of previous estimates, with implications for policy-relevant measurements of the Earth response to climate change, such as climate sensitivity to greenhouse gases and the thermal component of sea-level rise.
