The Climate Question28 Aug 2022

Can we engineer rain to help solve climate change?

From the Aztecs to the Zoroastrians, humans have always prayed for rain. We’ve tried dances, ritual sacrifices and even blowing up the sky to boost rainfall. This might sound crazy but desperate times call for desperate measures.

Climate change is making people desperate again, in some regions droughts are becoming more frequent and pervasive whereas in others floods threaten livelihoods and cities. We have already affected our weather cycle but can we control it? Many governments have turned to cloud seeding programmes to try to manipulate rain to fall where they desire it to. But does it actually work, and what are the potential ramifications? We speak to experts about how people are trying to create rain, whether we’re on the brink of a geopolitical nightmare.
