Machines to magic carbon out of the air, artificial intelligence, indoor vertical farms to grow food for our escape to Mars, and even solar-powered “responsible” yachts: the Cop28 climate summit in Dubai has been festooned with the promise of technological fixes for worsening global heating and ecological breakdown.
