The NYT is also very clear that it’s not cloud seeding:
Although some have speculated that recent cloud seeding efforts by the U.A.E. — using chemicals to increase the chances of clouds producing rain — could have contributed to the extreme weather, scientists said this was very unlikely.
“Rainfall enhancement could not cause that kind of increase in rainfall,” said Steven Siems, an expert in cloud seeding at Monash University in Australia, adding that any effects from cloud seeding would have been “marginal” at most.
