So, if an extreme climate change does occur in the future it could create widespread devastation.

Our concern is that human industrialization could be a trigger for extreme climate changes on a global scale in the future.

We have shown that there have been large fluctuations in water availability on a decadal to centennial time scale and that these changes occurred due to natural oscillations in climate.

From a human point of view, the more we know, the better off we'll be. In a region that is susceptible to droughts, wise water use and land management are a necessity.

Long droughts have been implicated in the collapse of many ancient civilizations on virtually every continent, including our example in eastern Africa, the Mayan in Central America and many others.

I like working on things that are very different and that involve different disguises.
