Seems to me that humans like to make sense of patterns from various random shapes - we just can't help it. Probably a defence system from when we had to spot tigers hidden in bushes. The most powerful demonstration of this is in 'A beautiful Mind'. Not saying this weather forecaster has mental health problems, but that once you start seeing patterns you can begin to link all sorts of things. My biggest problem with the conspiracy theory stuff is that if people have found a way to harness energy without any use of additional energy then
a/ what happened to entropy?
b/ why didn't anyone harness this energy for use - USSR could have done with it (next conspiracy theory - Exxon etc kept technology secret)
c/ the Japanese mafia???????????????

Much more interesting to try to understand the science of how these things really happen and enjoy the amazing effects they make, eg cloud formations. The weather is a much larger thing than humans can control, or even completely understand.

PS What was the weather like after Hiroshima and Nagasaki? Can't find any information. I would imagine that it would have had an effect.
