Debra Potvin from Gardnerville wrote in asking why don't they seed the clouds to make rain over Yosemite and other areas where fires are burning ?

Debra I checked with Justin Broglio up at the Desert Research Institute.
We have done a number of stories in the past about cloud seeding operations and how D-R-I uses the technology to beef up snowfall during winter storms.
  Unfortunately, that technology doesn't work during fire season.  Broglio says one reason is temperature.  The silver iodide crystals that they shoot in to the clouds to make snow flakes only work in freezing conditions.
   Another factor is moisture.   Silver iodide works by joining with existing cloud vapors. But when it comes to smoke clouds the relative humidity is very low in those clouds which prevents the kind of chemical reaction needed for cloud seeding.
So cloud seeding is effective at certain times of the year and it can be used to add to our winter snowpack.   But not when it comes to fighting fires.

Its called geo-engineering...aka,,weather modification. I was so proud of you guys for airing the protest that took place last week regarding chemtrails. Yet you seemed skeptical whether it was real. well, this is the same thing. Do more research you guys.

Idea? What about getting a big company like GE to make huge machines just off the coast to turn the ocean water into steam so then the water will settle on land in the USA?
