    Sulphur sunshade is a stupid pollution solution

    Geoengineering means intervening in the Earth's climate to offset global warming. It's hacking the planet on a monumental scale. The most widely studied proposal is spraying sulphate particles into the upper atmosphere to reflect sunlight, cooling the planet. The idea comes from huge volcanic eruptions, which can blast millions of tonnes of sulphur into the stratosphere, creating a kind of chemical sunshade. After decades of being taboo, this outlandish scheme is now being taken seriously.
