The paper linked below has detailed costings for various methods of injection. It's been out for a while, but I'm not sure it's received full attention. These estimates conflict with those in the Aurora report, which has perhaps received more attention.

Dear Nathan, I would sleep better at night if one government in the world was preparing to lead the battle to save the sea ice and prevent Arctic meltdown. While governments are being told that there is no immediate requirement for geoengineering and they should focus entirely on emissions

The appropriate rejoinder is often Compared to what? For example, What if the application is not spatially uniform? Uneven application results in uneven cooling, therefore pressure differences, therefore new winds are generated. Assuming spatially homogenous effects glosses over all that

Hi, John - Sorry if what I wrote came off as aggressive, but suggesting deployment of SRM in 9 months is itself aggressive provocative. Yes, there's plenty of evidence a big volcanic eruption provides quick, powerful negative forcing to the climate. So, on a local scale, does turning on

Hi, John - For me, there's a complex mix of facts and fictions in all this. In terms of Jennifer Francis her work, she wrote to your group specifically, after I suggested it, and stated that she emphatically did not think that arctic geoengineering (and this was on the assumption that the

Poster's note : it's a shame that the so-called 'Berlin declaration' has already been reported worldwide. I haven't spoken to anyone in Berlin who is openly supportive of the text, or most particularly the process. It's not come from the conference process, it's not been voted on, it's not been
