Dr Hugh Hunt: Can we refreeze the Arctic?

How can we cool the planet if (when) we fail to meet our CO₂ emissions targets? There are “geoengineering” technologies almost ready to go and some sound quite scary. Many pundits question whether it is safe to meddle with the climate when we only have one Earth, but others argue that we haven’t much time left before climate change runs away from us. This talk will present technologies which may be urgently required to slow down the progress of Arctic melting. The scale of the problem is huge, and we’re not well prepared.
