Dear Andrew and Bala, All your discussion you had during this post is very difficult to understand. Bala and the other authors of the article cited in the subject found with their model that a 2 X CO2 by the end of century will enhance gross primary production (GPP) and net primary production

Hi Andy, Don't you forgot giving the link to that article and the title and references of it? Bw Renaud Le mer. 29 avr. 2020 à 15:09, Andy Parker a écrit : > Hi all, > > > As some of you will know, the SRM Governance Initiative (SRMGI) funds a > number of pioneering SRM research projects in the

Re: [geo] What scares you most about SRM?

I can't consider as equivalent, or as comparable a full portfolio of very very different technologies, and talk about them indistinctly. Some are all over the entire world and show limited reversibility (SAI, 2 years to come back to initial if something unexpected and wrong happens), and others

Re: [geo] What scares you most about SRM?

Hi Andy, Reading you, I do not recognize SRM by MCB (marine cloud brightening), SRM by cool roofs, SRM by micron-size bubbles in water, SRM by ... many other techniques. I think you only speak about SRM by stratospheric aerosol injection. This should be clarified in the title and in the text.
