Data Center Description
For year after year across vast areas of North America rainfall was low. Summers were parched and the heat excessive. Plants withered and sand dunes moved freely across a formerly green landscape. Human settlements had to be abandoned and populations migrated, forcing social change. By some measures the drought lasted more than a decade.
