Ocean carbon uptake widely underestimated, say researchers
Shockingly – for some – nature’s ocean carbon cycle is functioning quite well, despite constant attempts by feckless humans to undermine it [/sarc]. Time to revisit those troublesome computer models yet again.

The world’s oceans soak up more carbon than most scientific models suggest, according to new research, reports Phys.org.
Previous estimates of the movement of carbon (known as “flux”) between the atmosphere and oceans have not accounted for temperature differences at the water’s surface and a few metres below.
The new study, led by the University of Exeter, includes this—and finds significantly higher net flux of carbon into the oceans.
It calculates CO2 fluxes from 1992 to 2018, finding up to twice as much net flux in certain times and locations, compared to uncorrected models.
“Half of the carbon dioxide we emit doesn’t stay in the atmosphere but is taken up by the oceans and land vegetation ‘sinks’,” said Professor Andrew Watson, of Exeter’s Global Systems Institute.
“Researchers have assembled a large database of near-surface carbon dioxide measurements — the “Surface Ocean Carbon Atlas” (http://www.socat.info) — that can be used to calculate the flux of CO2 from the atmosphere into the ocean.
“Previous studies that have done this have, however, ignored small temperature differences between the surface of the ocean and the depth of a few metres where the measurements are made.
“Those differences are important because carbon dioxide solubility depends very strongly on temperature.
“We used satellite data to correct for these temperature differences, and when we do that it makes a big difference—we get a substantially larger flux going into the ocean.
“The difference in ocean uptake we calculate amounts to about 10 per cent of global fossil fuel emissions.”
