And to be clear (as a coauthor), the particular choice of how the aerosols were distributed in this model *did* cool the oceans, just not as much as it cooled the global mean (atmospheric) temperature. So that (assuming one deployed this way, and that the model is correct) if one held global mean temperature constant, there would still be some parts of the ocean with some continued warming – though a lot less than if SAI were not deployed.
Not a panacea… As always, one needs to be careful in whether one is comparing to a world with the same CO2 emissions without geoengineering, or comparing to a world with the same global mean temperature due to lower CO2 concentrations. d From: geoengineering@googlegroups.com [mailto:geoengineering@googlegroups.com] On Behalf Of Renaud de RICHTER Sent: Monday, October 29, 2018 3:30 PM To: geoengineering <geoengineering@googlegroups.com> Cc: Stephen Salter <s.sal...@ed.ac.uk>; daisy.du...@carbonbrief.org Subject: [geo] Fwd: SRM ocean study Thanks Leon!

At least in carbon brief <https://www.carbonbrief.org/solar-geoengineering-may-not-cool-the-oceans-study-says> the author precises which type of geoengineering it is: Spraying aerosols high in the stratosphere could dampen global warming over land, but may not prevent the oceans from heating up, new research says. : The findings suggest that this type of “solar geoengineering<https://www.carbonbrief.org/explainer-six-ideas-to-limit-global-warming-with-solar-geoengineering>” – a set of techniques that aim to tackle global warming by reflecting sunlight back into space – may not necessarily stem sea level rise or prevent damage to the world’s marine ecosystems. ---------- Forwarded message --------- From: LDM <len2...@gmail.com<mailto:len2...@gmail.com>> Date: lun. 29 oct. 2018 à 19:43 Subject: SRM ocean study To: Renaud de RICHTER <renaud.derich...@gmail.com<mailto:renaud.derich...@gmail.com>> following what d macmartin was saying about specific injection of aerosols and showing the complexity of the problem direct link to the paper at the bottom of this article https://www.carbonbrief.org/solar-geoengineering-may-not-cool-the-oceans-study-says GEOENGINEERING<https://www.carbonbrief.org/category/science/temperature/geoengineering> 29 October 2018 16:00 Solar geoengineering may not cool the oceans, study says Spraying aerosols high in the stratosphere could dampen global warming over land, but may not prevent the oceans from heating up, new research says. -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
