It's tragic. I went to Bolivia for the Cochabamba People's Conference on Climate Change, but failed to get heard by the organisers, whereas the ETC group did manage. After the conference, I spent 6 months or more trying to contact the Bolivian Ambassador to UN, Pablo Solon, without success. The

John, I have no doubt that, from the perspective of many extant species and less-fortunate humans, we are indeed in dire straits. If I were convinced that stratospheric aerosols would work as advertised and that there would be no unforeseen or unanticipated repercussions, and that some sort of

Values and norms do and must guide what questions we ask, but they cannot be allowed to influence our scientific answers. Scientific papers should contain empirical statements and not value-based judgments. On Sat, Jul 23, 2011 at 4:44 PM, Jerome Whitington jwhiting...@dartmouth.edu wrote:

Deploy has an ominous and fateful ring. What about some careful, well thought through, limited experiments in order to decide about the value and risk of deployment? I think that is entirely possible with stratospheric aerosols. I think this group is entirely capable if defining and proposing

[geo] Prescriptive statements in scientific papers

2011-07-23 Thread Hawkins, Dave
Hi Ken, Your prescription that science papers should not include prescriptive statements raises interesting issues. While I agree that it is important to avoid confusion between science-based findings and statements based on values, it seems to me that it is possible to avoid this confusion in

David, In practice, that is what I do in public talks. I usually spend most of the talk on science and then i announce that i am moving from science to my own personal value-laden opinions and proceed to make a raft of prescriptive statements. If this is done in a written paper, I could live

Thanks, Dave, for the careful read and perspectives. I too am somewhat confused by the demarcation that Ken refers to. Isn't the entire field of geoengineering prescriptive and hence not science by Ken's definition? How can the science body IPCC publish numerous prescriptive tomes on CO2

Hi All - Forgive me for joining in - I am a newcomer on this list. Georges Canguilhem, who analyzed the French medical sciences, argued that the objectivity of medicine in fact requires its normative component. Research is not only motivated by goals like curing disease, but is organized toward
