This quickly degrades into another chemical, dimethyl sulphide, which generations of those subjected to unimaginative school lunches will instantly recognise.
In 1975 a lorry driver, Thomas Carroll, died after inhaling lethal hydrogen sulphide fumes given off by two toxic loads dumped in Pitsea, which made the press across the UK.
This would involve using sulphur or hydrogen sulphide aerosols so that sulphur dioxide would form clouds, which would, in turn, lead to a global dimming.
