In recent decades, scientists have developed sufficient monitoring capacity to understand how much of sea level rise is due to thermal expansion (from ocean heating) and melting land ice.

The Swedish professor also tells the BAZ that the rates of water rushing into the ocean due to glacier melt are exaggerated and that thermal expansion of the ocean is minimal.

Due to the increasing temperatures in the ocean found below 700m, it makes me wonder if due to the added pressure under the ocean, maybe the extra heat is due to the lack of thermal expansion, due to increased pressuDue to the increasing temperatures in the ocean found below 700m, it makes me wonder if due to the added pressure under the ocean, maybe the extra heat is due to the lack of thermal expansion, due to increased pressudue to the added pressure under the ocean, maybe the extra heat is due to the lack of thermal expansion, due to increased pressudue to the lack of thermal expansion, due to increased pressudue to increased pressure?

In draft versions at least, the new IPCC report does tackle the question of ice sheet loss, finding it «very likely» that melting ice and the expansion of the ocean due to its heating will lead to sea - level rise exceeding that of the last century.

The coastal lowlands are exposed to increasing rising tides due to thermal ocean expansion, which in turn increases the risk of flooding.

The second is what is termed as «steric change» — a scientific phrase that both identifies ocean thermal expansion due to warming combined with changes in ocean salinity, which also impacts sea surface height.

Ever since the early 1990s, scientific reports have highlighted the vulnerability of West Africa to inundation, flooding and loss of key industries, food growing and infrastructure due to glacial melt, thermal expansion of ocean waters set off by warming, and an increase in storm strength in the North Atlantic.

He was referring to the story where the scientist is saying the oceans are rising due to thermal expansion, and that is evidence of this whacked out, last gasp, theory they have about all the missing heat being trapped in the ocean depths.

Source: Lyman 2010 The reaction of the oceans to climate change are some of the most profound across the entire environment, including disruption of the ocean food chain through chemical changes caused by CO2, the ability of the sea to absorb CO2 being limited by temperature increases, (and the potential to expel sequestered CO2 back into the atmosphere as the water gets hotter), sea - level rise due to thermal expansion, and the amount of water vapour in the atmosphere.

With the recent GRACE adjustment, I wonder how the possible larger contribution of SLR due to thermal expansion fits in with measured sea ocean heat content?

Sea - level rise of nearly 1 metre by the end of the century (the upper estimate of the IPCC), due mainly to thermal expansion of the oceans, would see Bangladesh lose 14 per cent of its entire land area, causing a flood of environmental refugees.

My point is that reduction in Arctic / Antarctic ice uses almost no «global» heat, while raising sea - levels orders of magnitude (~ 120 times) more than thermal expansion due to heat transported into the deep ocean.

The sea level rise commitment due to thermal expansion has much longer time scales than the surface warming commitment, owing to the slow processes that mix heat into the deep ocean (Church et al., 2001).

There is a wide spread among the models for the thermal expansion commitment at constant composition due partly to climate sensitivity, and partly to differences in the parametrization of vertical mixing affecting ocean heat uptake (e.g., Weaver and Wiebe, 1999).

In addition, multidecadal measurements of steric sea level rise (a rise due to thermal expansion of sea water), and of ocean heat content have also been consistent with the temperature trends.

This expansion of OMZs is due to nutrient runoff makes the ocean more vulnerable to decreasing solubility of O2 in a warmer ocean.

As explained in the press release, the scientists began with the measure of sea level rise between 2005 and 2013, then deducted the amount of rise due to meltwater (e.g., melting ice sheets and loss of glacier mass worldwide) and then the amount of rise due to the expansion of water from the warming in the upper portion of the world's oceans (which scientists have good data on).

The answer is in thermal expansion of the ocean waters, which was greater in the early Eocene than in the late Cretaceous, due to greater temperature stratification of ocean water is the early Eocene versus the late Cretaceous.
