The Spread of Ocean Heat Uptake Efficiency Traced to Ocean Salinity

Geophysical Research Letters, 2023
Ocean heat uptake (OHU) plays an important role in determining the rate of surface warming under CO2 forcing. We examined the transient response to CO2 forcing in a set of 30 climate models from Coupled Model Intercomparison Project Phase 6 (CMIP6) and ...

Background Pycnocline Depth Constrains Future Ocean Heat Uptake Efficiency

Geophysical Research Letters, 2023
The Ocean Heat Uptake Efficiency (OHUE) quantifies the ocean's ability to mitigate surface warming through deep heat sequestration. Despite its importance, the main controls on OHUE, and on its two‐fold spread across contemporary climate models, remain ...

Decomposing oceanic temperature and salinity change using ocean carbon change [PDF]

Ocean Science, 2022
As the planet warms due to the accumulation of anthropogenic CO2 in the atmosphere, the interaction of surface ocean carbonate chemistry and the radiative forcing of atmospheric CO2 leads to the global ocean sequestering heat and carbon in a ratio that ...

Anthropogenic Aerosols Offsetting Ocean Warming Less Efficiently Since the 1980s

Geophysical Research Letters, 2023
Greenhouse gases and aerosols play a major role in controlling global climate change. Greenhouse gases drive a radiative imbalance which warms the ocean, while aerosols cool the ocean.

Earth's Energy Imbalance From the Ocean Perspective (2005–2019)

Geophysical Research Letters, 2021
Earth's energy imbalance (EEI) represents the rate of global energy accumulation in response to radiative forcings and feedbacks. Ocean heat uptake (OHU) poses a vital constraint on EEI and its uncertainty.

Stratification and overturning circulation are intertwined controls on ocean heat uptake efficiency in climate models [PDF]

Ocean Science
The global ocean takes up over 90 % of the excess heat added to the climate system due to anthropogenic emissions, thereby buffering climate change at Earth's surface. A key metric for quantifying the role of the oceanic processes removing this heat from

Mean ocean temperature change and decomposition of the benthic δ¹⁸O record over the past 4.5 million years [PDF]

Climate of the Past
We use a recent reconstruction of global mean sea surface temperature change relative to preindustrial (ΔGMSST) over the last 4.5 Myr together with independent proxy-based reconstructions of bottom water (ΔBWT) or deep-ocean (ΔDOT) temperatures to infer ...

The realized warming fraction: a multi-model sensitivity study

Environmental Research Letters, 2018
The degree of physical-biogeochemical equilibration of the climate system determines for how long global warming will continue after anthropogenic CO _2 emissions have ceased.

The influence of varying atmospheric CO2 on global warming potentials and carbon emission impulse response functions

Environmental Research Letters
Impulse response functions (IRF), the response in a climate parameter to an emission pulse of CO _2 , are used to characterize Earth system response timescales and to calculate Global Warming Potentials (GWPs).
