All weather is caused by heat. If you're looking for reasons why there seems to be more severe weather nowadays, it's more likely due to there being more heat energy trapped in our atmosphere now.
If it looks like a duck, walks like a duck and quacks like a duck it's probably ............. a duck!
Before someone says that the earth's rotation has something to do with it, this is a modifier, not a causation.
The energy involved in a hurricane is mind-blowing; something like a thousand hiroshimas spread across the system is one figure I've seen bandied about for a Cat 1 storm. I've no idea how true that figure is or whether that energy density is even remarkable - "statistics, more statistics and damned lies". What I am pretty sure about though is that it would be damned difficult to inject sufficient energy into a system to affect it in any way that could be called "control".
Y60 is right about the tsunami not being weather related. However, in both the tsunami and the hurricane disasters the environmental lobby would suggest that the net effect has been amplified by human inputs. In the case of the tsunami some have argued that global warming has caused the mean sea level to rise putting more people at risk. Again, no idea of the evidence behind that statement. In the case of the hurricanes that hit the southeast US every year, it's suggested as more people live there so for a given storm strength more people are at risk.
I'm no tree-hugger but it seems to me much more likely that Dubya is screwing with the weather by refusing to accept even the possibility of global warming. Having said that, if he had a bloody big ray gun I'm pretty sure the clown would be just itching to play with it.
But you're right, the supersecret hurricane generator works.
