Engineering the environment

I was listening to Michael Crichton's State of Fear last month (yes, listening and not reading - I finally subscribed to Audible). The book's excellent and well researched like most of Crichton's books. This book and some real life incidents have set me thinking.

In the book, an organization working for environmental protection and against global warming resorts to engineering natural disasters like a tsunami, hurricane and so on in order to prove its point that global warming is leading to disastrous changes in climate.

Over the past month two natural disasters occured that I am aware of - one was the torrential rains that hit Mumbai in the North of India and the other was the Hurricane Katarina that hit the Gulf Coast of USA. Both incidents resulted in unprecedented losses of life and property.

I'm not saying that these incidents are due to global warming. But I am thinking what would happen if real life mirrored fiction and terrorist organizations started engineering natural disasters by manipulating the environment? Would this lead to "eco"-terrorism?
