*Hi John,* I have said that your train of logic is just what we would be needing today. Go for your *manifesto,* I am all for it ! We have been talking about long term solutions for too long, let's act on the immediate term solution from *John * -- this might even buy us time to come up

Hi Peter‹Problem with your analysis is that biosphere also gives off something like 60 GtC as well. Preindustrial with steady CO2, as much was being taken up and given off. The net uptake, driven by the gradient created by emissions is now something like 1 GtC/yr and would equilibrate well before

Re: [geo] Re: Rejected - a simple argument for SRM geoengineering AND did you get that right?From Lenton and Vaughn (2009): First we consider the calculation of effects on atmospheric CO2 (deltaCatm) over time. Adding CO2 to the atmosphere or removing CO2 from the atmosphere triggers responses

Re: [geo] A simple argument for SRM geoengineering, again.I used sulphate as an example because my understanding is that this is the only SRM technology that we are confident would work. I think your interesting recent paper confirms that view, although it mentions a number of other
