I know most people here are aware that geo-engineering is not a new thing. Here's some evidence of how far it goes back.

BACKGROUND
The first cloud seeding project, intended to reduce hail east of the Mississippi River, was conducted in the Hudson River Valley of New York, just south of Albany, in 1956 and 1957. This was only a decade after the discovery of dry ice and silver iodide as nucleating agents by Drs. Vincent Schaefer and Bernard Vonnegut, working at the General Electric Research Laboratory in Schenectady, NY.
The first operational programs, designed to increase precipitation principally in the Catskill Mountains as an aid to the water supplies of New
York City, had been conducted in 1950-51. In May of 1956 a group, composed principally of apple growers, formed the Hudson Valley Crop Services Co-op. Mr. Walter Schreiber and Mr. Elmore Fraleigh, both of Red Hook, were elected President and Secretary-Treasurer. The Weather Modification Company, a commercial cloud seeding group in San Jose, CA, was hired by the Co-op to conduct operations to reduce hail. The designated project area was roughly 21 x 70 miles in Dutchess, Ulster, Columbia and Orange counties (Figure i).
