A global plan to put man-made particles into the atmosphere to deflect the Sun's heat would rapidly lower global temperatures until cuts in carbon dioxide emissions took effect, they argued.

They acknowledged concerns about geoengineering but said multi-national experiments should begin soon before it is too late to reverse climate change or in case a rogue state carried out separate measures.

Does anyone suppose someone will come up with the idea of triggering a volcano? If so, maybe it might not be containable, perhaps it's already started and started to go wrong?
