Laser Controlling Rain?

All I have to say is Leave Mother Nature Alone! Man is trying to play God once again, this time trying to manipulate the weather. Scientists are now saying that lasers can control rain. This isn't actually the first time I've heard of this. I recall a while back, China was messing with dispersing clouds with rockets.

According to foxnews, "A number of techniques have long existed to control rain by seeding the atmosphere with small particles of compounds such as dry ice and silver iodide that raindrops can grow around. However, "weather modification techniques have raised quite a lot of skepticism," said physicist Jérôme Kasparian, at the University of Geneva. [Image Gallery: Curious Clouds]

This controversy is due to questions of the effectiveness of such cloud seeding. The techniques spread chemicals quite widely, so given the variability of the atmosphere, it can be very difficult to judge how they may have actually affected the atmosphere, Kasparian explained.

Instead, Kasparian and his colleagues now reveal control over moisture using lasers. In experiments with infrared lasers over the Rhone River in Geneva employing a variety of temperatures, humidity levels and other atmospheric conditions, the scientists discovered that beams could trigger the growth of micron-sized water droplets even at a relatively low humidity of 70 percent, though not yet droplets large enough for rain."
