"What will happen to cities when the glaciers that provide all of their water resources evaporate over the years? There will be great human migrations in the future because people have fled their homelands. Greater than any world war or human conflict will this human migration will this be."

These nations will break down into war and conflict. More financial storms. More uncertainty. More fear. More flight. It is only the beginning."
