i believe the "'expert'" (i put your facetious quotes in quotes ) you refer to is Tim Flannery .. he might have some idea of what he is talking about. a lot of big name scientists think we might really be in the poo.
whether this is a good (or necessary) plan i dont know - but survival of the species > amateur astronomy viewing conditions
I am no climatologist, or atmospheric scientist (but then neither is Tim Flannery). However, I am a plant scientist and I did spend eight years doing research on climate change effects on plants. Flannery is a great publicist, and in that respect is doing a great job, but I'm not sure I've every heard many sensible ideas from him.
Look at that article, sulphur into the air will result in sulphuric acid rain, that would do the vegetation the world of good. CO2 into charcoal, how? The reason we get so much energy from fossil fuels is that it takes a lot of energy to get those carbon atoms to stick together. In other words we would need all the energy which we wasted in getting the CO2 into the air with our highly inefficient engines to get it back again. Where is that going to come from exactly?
I have called the Global Warming contingent the Sky is Falling Corporation in the past but never did I think I had come so close....
As everyone knows I am a crackpot so I am probably out of line to suggest the following radical moves....but perhaps before we sign the contact with the Sulphur Cloud Company we could explore some tactics to reduce our energy consumption...
Office light curfew would this save energy???, could we ban energy zapping car racing..formula one thru to whatever numbers...drag racing..boat racing..plane racing... in fact can we not ask the rich to refrain from their gross consumption of energy and decrying those in China and India who simply want to keep warm and have a fraction of the comfort of those greedily consuming way past their reasonable human entitlement take...
The global warming thing is a crook..not because it may or may not happen but because it is used simply as a tool to herd the sheep...
Al Gore is a business.... if you think otherwise you are a sheep...so dont feel guilty and change your light globe from 100 watts to 25 watts whilst the offices still glow all night and the race cars etc have simply no regard for the presented crisis...
If you think anyone can stop Global warming you have been sold a pup.. whilst you change your globes there are 600?700?800? new coal power stations are planned for China and India...
So in that context consider a world where we can still enjoy formula one racing, global warming has been stopped but every thing has been damaged by sulphuric acid....
Tim Tim... you are a player thats all you are.. any publicity is good publicity you seem to still subscribe to... but my friend a point comes where you rise to where you find yourself and accept the responsibility to at least try and say sensible stuff or you just stay a player to the other players in the room...
For my money your credibility is zip.. you were a political appointment timed to suit the GW band wagon...and the past PM's sudden realisation that GW was on us and that we needed nuclear power forthwith....who are you performing your tricks for now... where do your bones come from to suggest such stuff?
If I were you I would be adjusting my loyalties a little ..they dont need you anymore and they will need you less if you persist in stupid talk...
