And in 50-odd years the headlines will read "Turn everything on! Heat the planet before we all freeze to death!"
This idea is, of course, is nothing more than a salve to the American conscience. Something to make the Yanks think it is still A-OK to drive their 5-litre behemoth the 250 metres to the gym every other day. Because, yea, there is a ship at sea "off-setting" all that "heat".
Why not just blast a giant filter into space, place it between us and the sun. You could even make the opacity controllable. Heck, I am sure a clever person could even use it to write messages "Today brought to you by XYX Ltd. Yes, we commoditised the sun".
Either way, it amounts to the same thing. The Yanks can keep chugging that oil down (until the local supply runs low, then it's just a few wars to secure more) and do the square root of feck all to actually help the situation. Same holds true for China, S.Korea etc and will hold true for India et al.
Unless a politician can see a way of getting a tax from it, they don't care. In Europe we have the taxes, but they don't go to investment in viable renewables or anything. Nope, it's there to subsidise the champagne. You can tell that because the idiots still can't make up their mind where to have the EU parliament. If they really did see global warming (or whatever they call it this week) as a threat they would stay put in ONE building. And not a new one at that. Something recycled.
I suggest Sealand.
Then we can torpedo it and be done with the entire horde of parasites.
[Note to the CPS: The last line is not to be taken as a serious threat to torpedo Sealand or any other [ex-]military structure. Nor is is to be taken as a serious threat to attack MEPs or any of their unelected and secret committees. It is meant in as a satirical (well, OK, sarcastic) statement and a point of discussion, nothing more.]
