Can we make our own rain?
As droughts increasingly threaten regions worldwide,
scientists have proposed a solution straight from science fiction: engineering our own rain and clouds.
Cloud-seeding mimics the cloud forming process by releasing particles of silver iodide into the air.
Since silver iodide is assumed to be structured similarly to ice,
it could theoretically attract water droplets and vapor to ice nuclei, speeding up the cloud-forming process.
Over 52 countries have current weather modification programs–
but there’s still a lot of unknowns about cloud-seeding and its potential effects on the water cycle.
