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. |
Our concern is that human industrialization could be a trigger for extreme climate changes on a global scale in the future. |
So, if an extreme climate change does occur in the future it could create widespread devastation. |
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. |
