A disaster fantasy raises questions about tinkering with Earth's climate. With real-life scientists exploring geoengineering, what conversations should we be having now around these technologies?
The prospect of attempting to engineer the world's climate has become a lot more real since the Paris Agreement.
We have the technology to temporarily shift wet weather elsewhere.
It's a daunting technical challenge. But the key question is whether such engineering is socially acceptable.
Though climate engineering has lots of problems we need to do more than simply cut emissions.
