I agree with Ken’s comments to the authors, but wonder whether this concentration on geoengineering’s ‘termination problem’ couldn’t be used to rethink possible limits on large-scale aerosol SRM to make it more palatable and acceptable? Someone once posted, either in a ‘moral hazard’ thread or

The termination problem that poses the biggest threat is the termination problem related to fossil-fuel CO2 emissions. Were we to terminate such emissions today suddenly, there would global economic havoc (threatening the food supply of billions of people). Not only that, but the climate effects

The recent bright water discussions are interesting to me partly as a psychological phenomenon. Just as Seitz begins his paper noting the similarity between hydrosols in water and aerosols in air, with hydrosols having their attendant analogues to the “Twomey effect” – similarly complex issues of

Hi, Ken – I guess I’d add to the many posts on this thread – don’t forget to think both defensively and offensively, and since the amount of money is small, ways in which some of it might be able to act like seed money should be of interest. In the worst case, what could happen in a few years?

Hi, Ken - Of course you're right, but cessation of the industrial activity itself is certainly not what I meant by the termination problem of co-emitted aerosols with CO2. I meant the loss of the aerosol loading we are now facing from replacing coal, in particular, with new greener energy over

[geo] Emission cuts con trick

2011-04-25 Thread Andrew Lockley
In case anyone has fallen into the trap of believing politicians' claims on emissions its, the following article should dispel your optimism Of course, there are no cuts - merely accounting fiddles In my opinion, there won't be any in the near future, either. So its geoengineer or die.

[geo] Lackner/Bedini hybrid system for accelerated CCS

2011-04-25 Thread Michael Hayes
Hi All, I am proposing to significantly increase atmospheric CCS rates through the use of the Lackner type polymer-based ion exchange resin CCS system with the energy efficient ambient air flow induction potential of a Bedini Motor. The Bedini Motor US Patent is here
