Episode: Should we ‘dim the sun’ to save the planet?
Description: Scientists agree that cutting carbon emissions as soon as possible is key to tackling global warming. But as emissions continue to rise, some are now calling for more research into measures that could be used alongside decarbonisation, including – controversially – what’s known as ‘solar geoengineering’ technologies.
One idea being considered is spraying light-reflecting particles into the atmosphere to temporarily cool down the earth. It may sound far-fetched, but the idea is based on naturally observed effects following volcanic eruptions. Scientists are now asking whether we could mimic those effects to avoid the worst climate impacts.
But research into this technology...
