Nonetheless DEMOS, despite my mix-up between sulphate particles and SO2 this does have the appearance of a cheap and quick fix. Do you think the politicians will be able to resist?

I'm not asking whether you think this is a good idea. I doubt it is.

But I'm inclined to think that if the initial research holds up it's going to happen.

How much would it cost?

WE don't need to do anything.
The IPCC report assumed an unending supply of fossil fuels.
Read this and see what was overlooked;

Read his biography.

I tried the mirror thing ,every day after combing my hair I prop the mirror up on a stump in the yard, it had no effect apart from blinding a couple of birds and making them crash into trees, oh and getting bombed by a stray yank lost on his way to Iraq, he thougt it was a WMD.

Is there anything wrong with using a solution that is quick and cheap?

Firstly, thanks for the article it was an interesting read.

Not to sound too critical but you say you're not asking whether we think it's a good idea but you asked for any comments. I think it being a bad idea and reasons for that help answer the other question:
"Can anything stop politicians taking what may appear to be a quick and easy way out of a dilemma?"

My comments are:
It's a bad idea because there is more than one reason why we should not be dependent on fossil fuels. Oil can be used to produce plastics and other useful things; yet we're determined to burn every last drop for the purposes of personal transport. Global warming is an effective stimulus for change toward a more sustainable existence. Ideally we would consume only renewable resources as to leave future scientists as much resources as possible to experiment with.

My response to the second question is:
Governments should take a responsible approach taking into account the future of the human race. We'll make life a lot harder for ourselves if we have less resources in the future. Just like biodiversity is important i think a wide variety of resources is important. Obviously the most cost effective path will be taken and so if this proves possible i think there will be little to stop governments from pursuing it. It's possible (maybe likely) we will take the quick fix and keep blindly polluting and squandering our finite resources but i hope not.
