I should put this in "
Water where will it come from in 2050?" thread but as we we discussing this I thought you may be interested in this new, long-term research on cloud seeding.

The cloud seeding operation has resulted in more rainfall, according to new research.
A team of researchers at Monash University has released a new analysis of precipitation records from the long-term cloud seeding operation in Tasmania that shows a promising increase in rainfall during periods of seeding.
The team worked with Hydro Tasmania analysing the cloud seeding activity over the hydroelectric catchment area in central Tasmania for more than four decades - from 1960 to 2005.
Associate Professor Steven Siems, Faculty of Science said the analysis used monthly rainfall figures in the catchment area where the seeding took place and compared it with data from nearby control areas.
"A number of independent statistical tests showed a consistent increase of at least 5 per cent in monthly rainfall over the catchment area. This is the first time that an independent analysis of cloud seeding data over several decades has shown a statistically significant increase in rainfall," Associate Professor Siems said.
