CHEYENNE, Wyo. (AP) - The Wyoming Legislature has provided an additional $2.4 million to complete a cloud seeding research project and ensure that it will have scientifically sound results.
The state has invested about $11 million since 2005 in the project, which seeks to determine whether cloud seeding increases the amount of snowpack in several of the state's mountain ranges.
Most of Wyoming's water supply comes from winter snowfall. Supporters of the project say increasing the state's winter snowpack would provide more water for communities and irrigation and would be cheaper than building new dams and reservoirs.
Barry Lawrence, of the Wyoming Water Development Office, says the project will go on for two more winters and a report is planned in late 2014.
Cloud seeding is a form of weather modification. It is not considered geoengineering because it does not affect climate

The trouble is, people seem to think it has something to do with "chemtrails" which are left by high altitude aircraft (contrails).

My mom said my grandpa came out to Laramie in the 60's to work on their cloud seeding project. I've known about this since I was a little kid, early 80's. I understand the argument over whether it happens on large scale, but I remember a time on ATS when it seemed there were a large number of deniers (a couple years ago, during the height of the "contrail" interest). Honestly all I could do is sit back and watch in amusement....
Cloud seeding didn't begin until the late 1940's....

Cloud seeding is a form of weather modification. It is not considered geoengineering because it does not affect climate.
The chosen seeding strategy (one of many possible scenarios) can restore global averages of temperature, precipitation and sea ice to present day values, but not simultaneously. The response varies nonlinearly with the extent of seeding, and geoengineering generates local changes to important climatic features. The global tradeoffs of restoring ice cover, and cooling the planet, must be assessed alongside the local changes to climate features.

Cirrus cloud seeding using airliners to reduce reflectivity.
Latham [3, 4] suggested that the planetary albedo might be increased by changing the albedo of maritime boundary layer clouds by seeding them with aerosol produced from seawater.
