Web3 Dec 2004 · All that the lag shows is that CO 2 did not cause the first 800 years of warming, out of the 5000 year trend. The other 4200 years of warming could in fact have been caused by CO 2, as far as we can tell from this ice core data. The 4200 years of warming make up about 5/6 of the total warming. So CO 2 could have caused the last 5/6 of the ...

Web8 Jun 2024 · Within days, Severinghaus had begun the design of a water bath containing the PCO2 and PO2 electrodes, with a stirred cuvette for the Clark electrode. “Clark’s electrode was the key discovery,” said Severinghaus. “Fifty years later, every blood gas analyzer contains a Clark type electrode.”
Web11 Nov 2013 · In 1960, Severinghaus described the measurement of P co2 via human skin using a specially designed, temperature-stabilized tissue P co2 electrode ( 15 ). This technique was further developed by local heating, which allowed the continuous measurement of blood gases by arterialization of the cutaneous tissue ( 16 ). Web14 Mar 2003 · The sequence of events during Termination III suggests that the CO2 increase lagged Antarctic deglacial warming by 800 ± 200 years and preceded the Northern Hemisphere deglaciation. The analysis of air bubbles from ice cores has yielded a precise record of atmospheric greenhouse gas concentrations, but the timing of changes in these …
WebA Ag/AgCl reference electrode was placed under the membrane as well. J. W. Severinghaus improved this design by adding a source of bicarbonate ions to the electrolyte solution. By doing this, the pH of the inner solution became linked to the partial pressure of p CO 2 outside the membrane by a simple mathematical equation, now commonly known as the …
