According to a program I slightly remember on TV, too much tampering could screw up seasons and what not. So? The closer this brings us to WEATHER CONTROL! And Mother Nature is a woman, sweet but a wrath of anger at times. I like her. Well say for example you stimulate lots of rain during the winter, by the spring, when you may need them again, they may not come. It takes time for moisture to build in the air and the right currents have to be in place to transfer clouds over to a certain area. We can just force that, too. Not if those clouds aren't even formed yet We can force the clouds to form. We're stronger than they are. Oh you're joking again
