Dear all
In response to the query below, I have provided Renaud de Richter with pdfs of papers describing the 'cloud treatment' technology, including the following: Amirova S & Tulaikova T (2015) The atmospheric CO2 purification method. Global Journal of Science Frontier Research H: Environment & Earth Science, 15 (1) [no page numbering] Amirova S & Tulaikova T (2015) One possibility for atmospheric CO2 purification to get climate recovery. Science Discovery 3 (2-1), 1-6 Google Scholar searches for Tamara Tulaikova will give others. It is questionable whether such ideas should be taken seriously. I suspect there would be i) high costs involved for scale-up to have significant climatic effect; and ii) major problems regarding governance and acceptability. References to this technique were not given in the Nature article, not only because of the above considerations but also because there were tight constraints on the number of citations that could be included in a Comment article (normally limited to 10). I am happy to share pdf's with others if they are sufficiently interested and have problems in tracking them down (the journals are not listed in Web of Science).

Cloud treatment to increase alkalinity (alkaline rain resulting from cloud treatments removes atmospheric CO2) ? Are there scientific publications on this CDR proposal? Is it described somewhere on the Internet? Has anybody an answer? Thanks!

Can somebody explain what exactly is the 8th CDR technology cited: "Cloud treatment to increase alkalinity"? Alkaline rain resulting from cloud treatments reacts with, and removes, atmospheric CO2. Are there scientific publications on this CDR proposal? Thanks R. de_Richter -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
