… [W]hat’s now known as geoengineering remains a strange, somewhat ad hoc field even today. A recent report by the Government Accountability Office, or GAO, found that the federal government still does not have sufficient oversight over weather modification activities and is also “not fully meeting its responsibilities to maintain and share weather modification reports.” … As drought intensifies and water demand increases across the West, states have been ramping up cloud-seeding efforts, as one way to work around the lack of water. …  Cloud seeding alone can’t fix that. Another report from the GAO last year found that the process still needs more research to determine how well it works and why.
