List 1. The subject of ethics and morality have been key to this list discussions, especially over the last week. .As I was further researching this list's discussion on this topic, I came on a short message string introduced by Andrew Lockley on April 11. Andrew, as is his welcome style, aler

Our latest offering on abiotic CDR can be found here: http://www.pnas.org/content/early/2013/05/30/1222358110.full.pdf Some highlights: air CO2 captured and safely stored - check carbon-negative H2 produced - check ocean alkalinity beneficially increased, OA and impacts reduced - check <$100/tonne

I think it's important to distinguish between the effects of advocacy and the inertia of the energy system. I believe the inertia is huge relative to the effects of advocacy because of the tremendous switching costt of infrastructure, distribution, power systems. Advocacy affects choices at the m

Dear Stephen, My list of 26 problems is in slide 157 of http://climate.envsci.rutgers.edu/RobockGeoEngineering72ForDistribution.ppt I have been mainly focused on stratospheric aerosols. My latest publication on this is a response to Seitz's bubbles proposal at http://climate.envsci.rutgers.e

Dear Alan Can you tell me which of your 26 objections apply to marine cloud brightening? I am sure that many of the people who want research on but not deployment of geoengineering systems are greatly reassured that you are there to spot the nasty problems. Keep up your valuable work. I t

Dear All, I also was at the NASA Ames meeting. It was my first geoengineering meeting, and it was there that I was struck with the very enthusiastic endorsement of geoengineering as a solution to global warming by people who did not seem to be aware of the potential negative impacts. But Lane

Clive's problem is that he seems to think Haroon and Lee are foxes. And that anyone associated in any way with organizations like AEI and Exxon must be a fox. And that anyone who doesn't realize this must be naive. He's wrong. Tom. ++ On 6/1/2013 6:05 AM, euggor...@comcas

Much less about misunderstanding at all about the issue of saturation, a criticism of Arrhenius that has been addressed many, many times and kicked out of science as an issue by Manabe and others in the 1960s. Mike On 5/31/13 1:33 PM, "David Lewis" wrote: > According to the University of Water
