An industrial solution for an industrial problem?
Tech tells us that our planet is heating up. The hottest years ever recorded, in order, are: 2015, 2016, 2017, to be followed, probably by 2018. We’re pumping out carbon dioxide, which traps heat in our atmosphere. Hence the name ‘greenhouse gases’. Earth-orbiting satellites have recorded it all, and scientists now say it’s 95% likely to be the result of human activity since the mid-20th century. Polar ice caps are melting, sea levels are rising, the oceans are getting warmer and more acidic. Tropical cyclones are on the increase.
What if the answer was to spray chemicals into the atmosphere and the oceans to counteract the effects of greenhouse gases? This is geoengineering, a range of complex and controversial techniques that are set to one day be used to tinker with global weather systems.
