[…] In 2007 Andrew Heymsfield … was a on a research flight west of Denver International Airport when he and his team flew right below a big [cloud that had been flown through by an airplane]. When they went back and looked at footage from a ground-looking camera on the plane, they found the area directly beneath the hole had been coated in two inches of fresh snow. […]

“Cloud seeding experiments began in Australia just a year after the world’s first laboratory trials in the USA.

From 1947 to 1952, CSIRO scientists used Royal Australian Air Force aircraft to drop dry ice into the tops of cumulus clouds. The method worked reliably with clouds that were very cold, producing rain that would not have otherwise fallen.

CSIRO carried out similar trials from 1953 to 1956 in South Australia, Queensland and other States. Experiments used both ground-based and airborne silver iodide generators.

During the late 1950s and early 1960s, CSIRO performed cloud seeding in the Snowy Mountains, on the York Peninsular in South Australia, in the New England district of New South Wales, and in the Warragamba catchment area west of Sydney. ”

I reposted this in honor of the Republican Party and its constituents and others like them. You see, even amid topics now drenched with Teh Crazy, in this case Chemtrail Theory, there is sometimes real, interesting science. The rest of us will be enjoying that while you are making up reasons that Romney did not win and talking about how Sandy was not a Hurricane and how Global Warming isn’t Real and men are sexually violated as often and as severely as are women. Etc.
