[1] We review the sea-level and energy budgets together from 1961, using recent updated estimates of all terms. From 1972 to 2008, observed rise (1.8 ± 0.2 mm yr−1 tide gauges alone 2.1 a combination altimeter observations) agrees well with sum contributions 0.4 yr−1) in magnitude both having similar increases rate during period. The largest come ocean thermal expansion (0.8 melting glaciers ice caps (0.7 yr−1), Greenland Antarctica contributing about yr−1. cryospheric increase through...
Abstract. Global mean sea level is an integral of changes occurring in the climate system response to unforced variability as well natural and anthropogenic forcing factors. Its temporal evolution allows (e.g., acceleration) be detected one or more components. Study sea-level budget provides constraints on missing poorly known contributions, such unsurveyed deep ocean still uncertain land water component.

Abstract. Human-induced atmospheric composition changes cause a radiative imbalance at the top of atmosphere which is driving global warming. This Earth energy (EEI) most critical number defining prospects for continued warming and climate change. Understanding heat gain system – particularly how much where distributed fundamental to understanding this affects ocean, land; rising surface temperature; sea level; loss grounded floating ice, are concerns society. study Global Climate Observing...
The energy radiated by the Earth towards space does not compensate incoming radiation from Sun leading to a small positive imbalance at top of atmosphere (0.4-1.Wm-2). This is coined Earth's Energy Imbalance (EEI). It mostly caused anthropogenic greenhouse gases emissions and driving current warming planet. Precise monitoring EEI critical assess status climate change future evolution climate. But challenging as two order magnitude smaller than fluxes in out Earth. Over 93% excess that gained...
Abstract. We introduce ACCESS-OM2, a new version of the ocean–sea ice model Australian Community Climate and Earth System Simulator. ACCESS-OM2 is driven by prescribed atmosphere (JRA55-do) but has been designed to form component fully coupled (atmosphere–land–ocean–sea ice) ACCESS-CM2 model. Importantly, available at three different horizontal resolutions: coarse resolution (nominally 1∘ grid spacing), an eddy-permitting 0.25∘), eddy-rich (0.1∘ with 75 vertical levels); be incorporated into...
Abstract. The Earth climate system is out of energy balance, and heat has accumulated continuously over the past decades, warming ocean, land, cryosphere, atmosphere. According to Sixth Assessment Report by Working Group I Intergovernmental Panel on Climate Change, this planetary multiple decades human-driven results in unprecedented committed changes system, with adverse impacts for ecosystems human systems. inventory provides a measure imbalance (EEI) allows quantifying how much as well...
Abstract A time-varying warm bias in the global XBT data archive is demonstrated to be largely due changes fall rate of probes likely associated with small manufacturing at factory. Deep-reaching XBTs have a different history than shallow XBTs. Fall rates were fastest early 1970s, reached minimum between 1975 and 1985, another maximum late 1980s 1990s, been declining since. Field XBT/CTD intercomparisons pseudoprofile technique based on satellite altimetry confirm this time history....

Ocean reanalyses combine ocean models, atmospheric forcing fluxes, and observations using data assimilation to give a four-dimensional description of the ocean. Metrics assessing their reliability have improved over time, allowing become an important tool in climate services that provide more complete picture changing end users. Besides monitoring research, are used initialize sub-seasonal multi-annual predictions, support observational network monitoring, evaluate model simulations. These...
Abstract Ocean warming accounts for the majority of earth’s recent energy imbalance. Historic ocean heat content (OHC) changes are important understanding changing climate. Calculations OHC anomalies (OHCA) from in situ measurements provide estimates these changes. Uncertainties OHCA arise calculating global fields temporally and spatially irregular data (mapping method), instrument bias corrections, definitions a baseline climatology which calculated. To investigate sensitivity upper 700 m...
A major challenge for managing impacts and implementing effective mitigation adaptation strategies coastal zones affected by future sea level (SL) rise is our very limited capacity to predict SL change on scales, over various timescales. Predicting requires the ability monitor simulate a multitude of physical processes affecting SL, from local effects wind waves river runoff remote influences large-scale ocean circulation coast. Here we assess current understanding causes variability...
Abstract A striking feature of the South Indian Ocean circulation is presence eastward Countercurrent (SICC) that flows in a direction opposite to predicted by classical theories wind‐driven circulation. Several authors suggest SICC resembles subtropical countercurrents (STCCs) observed other oceans, which are defined as narrow jets on equatorward side gyres, where depth‐integrated flow westward. These associated with subsurface thermal fronts at thermocline depths wind relation. However,...
The first eXpendable BathyThermographs (XBTs) were deployed in the 1960s North Atlantic Ocean. In 1967 XBTs operational mode to provide a continuous record of temperature profile data along repeated transects, now known as Global XBT Network. current network is designed monitor ocean circulation and boundary variability, basin-wide trans-basin heat transport, global regional content. ability Network systematically map upper thermal field multiple basins with sections at eddy-resolving scales...
Abstract We present an ensemble approach to quantify historical global mean sea-level (GMSL) rise based on tide gauge reconstructions. This combines the maximum internal uncertainty across with estimate of structural provide a conservative total uncertainty. Comparisons GMSL over 20th century deltas and linear trends (and their respective uncertainties) are consistent past Intergovernmental Panel Climate Change assessments show good agreement satellite altimeter timeseries.
