    Can either of you confirm whether there is any connection / correlation between the heavy rains (and hail) we have just experienced and the tons of combustion particles that went up in smoke as pyrocumulus clouds during the three month long bush fire crisis Australia has just suffered?  Or is this simply a co-incidence?

    Thank you George – always good to have input from someone that has had your depth of experience.

    Thank you too for the Pewtrusts link, the information from which I have found most interesting. The severe droughts farmers have been experiencing in Australia over the last decade, said to be “the longest in living memory”, have broken at last what with much of the drought affected areas now under metres of water, roads cut off and floods downstream. It is simply the timing of such events that doesn’t always meet human needs?

    Hello Hans – the man to ask is no one else than the founder of the CAS himself, Gavin Pretor-Pinney! In his book he describes the top secret programme adopted by the Americans to spray chemicals into the clouds over Laos, Vietnam and Cambodia in order to create rain, extend the monsoon season and thereby disrupt enemy movements along the Ho Chi Minh trail (a major infiltration route). Given the code name Project Popeye the idea was to “make mud not war’. Tests were conducted in 1966 over the Annam Mountain Range in Laos.

    Another source of information is Mark Miodownik (author of book ‘’Liquids’’, 2018). He maintains cloud seeding, regarded as “one of the most extraordinary experiments of the 20th century”, was invented in 1946 by an American scientist called Vincent Schaefer. He and his team maintained that by dispersing silver iodide crystals into the atmosphere they would act as nucleating droplets (like dust or smoke particles do) which would produce snow and rain.
